MODES FOR CARRYING OUT THE INVENTION

[0073] The embodiments presented herein refer to a formula car and all particular values of forces will be presented with reference to this motor sport. In case of other motor sports, such as airplanes or speed boats, other forces may apply and appropriate adjustments may be made.

[0074] FIG. 1 depicts a section of a formula car comprising the head and neck support and protection device according to the present invention. The head and neck support and protection device comprises an arm 1, having a slidably-mounted element 2 for releasably (preferably) connecting it to a helmet clip 3.

[0075] The slidably-mounted element 2 may slide on or within the arm 1 depending on the selected embodiment. In a preferred embodiment of the device, the slidably-mounted element 2 slides within the arm 1, in a hollow portion adapted for this purpose.

[0076] The helmet clip 3 is configured to engage a helmet pin 22 (shown in the remaining drawings), preferably being releasably fixed to a helmet 5. The helmet clip 3, depending on its embodiment, allows for left/right rotational head movement or full movement as naturally allowed by the wearer's neck.

[0077] Preferably, the helmet clip 3 has a quick release system, activated when pulled up, which at the same time may not accidentally release while driving.

[0078] Under the arm 1, there is positioned a resistance block 4, fixed to the chassis, forming a support for the arm 1 during vertical movements (towards the bottom of the vehicle) of a helmet 5 clipped to the helmet clip 3. In its closed position, when the slidably-mounted element 2 engages the helmet clip 3, the arm 1 preferably rests on the block 4 (or is relatively close to it).

[0079] In other embodiment, the arm 1 is preferably spaced by less than 1 cm from the block 4. In case of an impact from the top, the arm 1 will be blocked by the resistance block 4.

[0080] The resistance block 4 therefore, disallows excessive movement of the helmet 5, attached to the device according to the present invention, downwards beyond natural movement range of a driver's head. Thus, injuries arising from pushing one's head downwards, while being sited are hereby addressed.

[0081] The natural movement range obviously depends on the particular driver and may be adjusted.

[0082] A further embodiment of the spacing between the arm 1 and the resistance block 4 will be shown with reference to FIG. 29.

[0083] The arm 1 may comprise a mounting element (e.g. opening) 6 for receiving a carrying shaft 7 (shown in FIG. 2) in order to form a pivotable connection. Thus, the arm 1 is rotatably/pivotably mounted to a support (be it the resistance block 4 or the formula car chassis). Advantageously, the arm 1 is positioned in the middle of the carrying shaft 7 (shown in FIG. 2).

[0084] The rotatable/pivotable mount allows for the arm 1 to move away from the helmet, when the helmet clip 3 is disengaged, in order to facilitate easier positioning for the driver.

[0085] As shown in FIG. 2, the arm 1 has the helmet clip 3 at its end opposite to the pivotable mount.

[0086] In preferred embodiments the slidably-mounted element 2 and the resistance block 4 are made from titanium, graphene, carbon fiber or similar.

[0087] In FIG. 1A the head and neck support and protection device, according to the present invention, is shown in its opened form, ready to mount a helmet 5 worn by a driver.

[0088] FIG. 2 shows an exploded view of the head and neck support and protection device according to the present invention. The arm 1 (preferably L-shaped or J-shaped or S-shaped or Z-shaped or Y-shaped or the like) is preferably positioned such that its longer section extends towards the helmet 5 while its shorter section extends towards the bottom of the vehicle. The shape of the arm 1 mainly depends on the shape of the chassis and available space.

[0089] In another embodiment of the present invention, the head and neck support and protection device may have its shape adapted to the size and shape of the helmet 5 as well as the shape of the chassis in dependence with the constructional requirements.

[0090] In case of an L-shaped arm 1, as shown in FIG. 2, its longer section is arranged substantially horizontally (while pointing towards a direction of movement of a respective vehicle) while its short section is arranged substantially vertically (pointing downwards of the respective vehicle).

[0091] The arm 1 may comprise a mounting element 6, 8 for receiving the carrying shaft 7. In a particular embodiment, the mounting element may be an opening 6, positioned in an axis perpendicular to the length of the arm 1, the opening 6 being positioned at the far end of the shorter section of the arm 1. Further, there may be present a hollow section 8A in the mounting element, such that two arms 8 with respective openings 6 are present, as shown in FIG. 2 (the carrying shaft 7 is to be inserted perpendicularly to the axis of the longer section of the arm 1).

[0092] The carrying shaft 7 may comprise a lengthwise groove 9, while there may be present a spring element 10 between the two arms 8. The spring element 10 has a bent section 10A that fits the lengthwise groove 9.

[0093] The spring element 10 partly surrounds the carrying shaft 7 (preferably to the extent allowed by the hollow section in the mounting element) while the other end 10B of the spring element 10 adheres, with its flat surface, to the arm 1 between the two arms 8 as shown in FIG. 2. The flat surface acts like a spring and neutralizes the weight of the helmet and the device itself. Owing to that, the helmet 5 may be heavier and thereby safer since the driver will not feel the extra weight.

[0094] The carrying shaft 7 may be connected to the chassis so that it is positioned parallel to the left-right axis of the vehicle. For this purpose the carrying shaft 7 may comprise, preferably at its ends, threaded openings 7B, in which there may be positioned threaded mandrels 11, preferably comprising nests for an allen key 12.

[0095] The other ends of the threaded mandrels 11 are mounted to threaded elements 13, being preferably inner-threaded bushes, fixedly mounted to a chassis of a vehicle.

[0096] With a use of an allen key, one may adjust the positioning of the carrying shaft 7 in the vehicle's chassis, depending on the driver's height and positioning of the respective helmet 5.

[0097] On the carrying shaft 7, between the arm 1 and each of the threaded mandrels 11, there are preferably positioned helical springs 14 of the carrying shaft 7. The helical springs 14 prevent excessive movement of the helmet 5 while taking corners (due to high centrifugal force) as well as during impacts into the helmet 5 from the left/right side. At the same time, the helical springs 14 allow some movements, which feels more comfortable.

[0098] The slidably-mounted element 2 comprises a lengthwise groove 15 (preferably at a side facing downwards) while the arm 1 comprises, in its longer section, at least one opening for receiving a limiter 16 for limiting movement of the slidably-mounted element 2 within the arm 1. The limiter 16 may be a screw, preferably made from steel, which moves in the lengthwise groove 15.

[0099] When a driver's head moves forward together with the helmet 5, the limiter 16 limits the length, by which the slidably-mounted element 2 may pull out from the arm 1.

[0100] In the arm 1, there may be present a protective pin 17, for example a screw made from a soft metal or plastic (depending on the requirements, the protective pin 17 must be cut in case of a force equal or above 7 g). In case of an abrupt movement of the slidably-mounted element 2 out of the arm 1, typically caused by hitting an obstacle, the protective pin 17 is cut (by a force acting on the slidably-mounted element 2 wherein the force is a result of a crash).

[0101] Between the arm 1 and the slidably-mounted element 2, there are bars comprising bearing elements 18 (as shown in FIG. 25) facilitating movement of the slidably-mounted element 2.

[0102] Alternatively, between engaging planes of the arm 1 and the slidably-mounted element 2, there is a friction reducing agent, preferably a suitable lubricant or a Teflon layer.

[0103] The end of the slidably-mounted element 2, protruding from the arm 1, is in this embodiment releasably connectible to the helmet clip 3. Preferably, the connection is a bolt 19 connecting suitable elements 20, 21 of the slidably-mounted element 2 and the helmet clip 3. The bolt is preferably inserted perpendicularly to the axis of the longer section of the arm 1.

[0104] In a preferred embodiment, to this end the slidably-mounted element 2 comprises an opening 21 (preferably in a suitable ear mount with an opening positioned perpendicularly to the axis of the longer section of the arm 1) for receiving the bolt 19 while also the helmet clip 3 comprises a similar opening 20 (preferably in a suitable ear mount with an opening positioned perpendicularly to the axis of the longer section of the arm 1) for receiving the bolt 19, as shown in FIG. 2.

[0105] Thus, the bolt 19 positioned in the openings 20, 21 will connect the helmet clip 3 and the slidably-mounted element 2 once a nut 19A is fixed on the bolt 19. Naturally, other connecting means than a nut 19A may be applied as will be evident to one skilled in the art.

[0106] The connection between the slidably-mounted element 2 and the helmet clip 3 may be fixed, as shown in FIG. 2, or pivotable as shown later with reference to FIG. 20 and FIG. 21.

[0107] In this embodiment, the helmet clip 3 allows for connecting a helmet pin 22 and has a hollow portion extending throughout its height 3A (shown in more details in its cross-section shown in FIG. 8).

[0108] The helmet clip 3 comprises a head 23 having a rotation limiter of the helmet pin 22, a helical spring 25, blocking balls 26, the helmet pin 22, preferably comprising a circumferential groove 27 for receiving the blocking balls 26, and a clamp ring 28 comprising a grip 29 of the clamp ring 28.

[0109] The helical spring 25 is mounted on the head 23 (adhering to its external side walls). Next, the blocking balls 26 are input into the cavities (present at its circumference as shown in FIG. 2) in the head 23. The head 23 is positioned, from the top via the respective opening, in the helmet clip 3. The helical spring 25 holds the blocking balls 26, while the clamp ring 28 keeps all these elements in the helmet clip 3, until release.

[0110] The helmet pin 22, comprises a delimiting protrusion 30 at its top section, engaging a rotation limiter (elements 30 and 24 as shown in more details in FIG. 7) of the helmet pin 22, which results in limiting left-right, rotational, head movement of the driver.

[0111] The hollow portion 3A, extending throughout the height of the helmet clip 3, may be preferably covered with a corresponding protective cap 31. In another embodiment of the present invention, the hollow portion 3A of the helmet clip 3 may only be a cavity for receiving elements 23-29.

[0112] FIG. 3 presents an exploded view, from the bottom, of the head and neck support device. The arm 1 has, at its longer section, at least one threaded opening 16A allowing for adjusting a length of movement of the slidably-mounted element 2 depending, in which threaded opening a limiter 16 is screwed in.

[0113] The protective pin 17, positioned in a blocking opening in the arm 1 (herein the blocking opening is positioned at the bottom of the longer portion of the arm 1), is also positioned at the same time in the respective opening 17B in the slidably-mounted element 2.

[0114] Thus, the slidably-mounted element 2 is configured to slide out of the arm 1, in a controlled manner, when conditions indicating a crash have been met.

[0115] A variant of the carrying shaft 7, shown in FIG. 3, has its ends positioned in bushes fixed to the threaded mandrels 11, which are fixed with their far ends to the threaded elements 13, being preferably inner-threaded bushes, fixedly mounted to a chassis of a vehicle.

[0116] FIG. 4 depicts a lengthwise cross-section of the arm with a helical spring 33 inside it. The helical spring 33 extends lengthwise, inside the slidably-mounted element 2 and the longer section of the arm 1.

[0117] One of the ends of the helical spring 33 may be fixedly mounted to the arm 1 while the other end may be fixedly mounted to the slidably-mounted element 2 in proximity to the opening 21. The function of the helical spring 33 is to restrain movement of the slidably-mounted element 2.

[0118] FIG. 5 depicts a lengthwise cross-section of the arm with a damper. The function of the damper 34 is to restrain movement of the slidably-mounted element 2. One of the ends of the damper 34 may be fixedly mounted to the arm 1 (further end from the helmet clip 3) while the other end may be fixedly mounted to the slidably-mounted element 2 in proximity to the opening 21.

[0119] A suitable damper may be an oil damper, air dumper or a gas spring or an alternative element serving the same function.

[0120] FIG. 6 depicts a lengthwise cross-section of the arm with an elastic cord 35. The function of the elastic cord 35 is to restrain movement of the slidably-mounted element 2. One of the ends of the elastic cord 35 may be fixedly mounted to the arm 1 (further end from the helmet clip 3) while the other end may be fixedly mounted to the slidably-mounted element 2 in proximity to the opening 21.

[0121] The helical spring 33, the damper 34 and the elastic cord 35 are all internal braking elements configured to brake sliding of the slidably-mounted element 2 out of the arm 1.

[0122] As shown in FIGS. 4-6, the slidably-mounted element 2 may, during normal driving, either (A) be substantially fixed (not movable) or (B) movable.

[0123] In the variant (A), the helical spring 33 and/or damper 34 keep the driver's head substantially fixed and preferably significantly limit the linear forces (in the axis of the length of the longer section of the arm 1) in a range of up to 6-7 g. When a force in a range of 6-7 g is reached (i.e. when conditions indicating a crash have been met), the protective pin 17 is cut and the slidably-mounted element 2 moves forward (to its maximum extent allowed in order to protect from neck injury.

[0124] The maximum extension allowed, of the slidably-mounted element 2, depends first on the driver and second on the physical structure of the formula car, but typical values will range from 5 to 10 centimeters.

[0125] In the variant (B) the helical spring 33 or damper 34 or the elastic cord 35 allow for some head movement, depending on driver's preferences, in a range of up to 6-7 g.

[0126] FIG. 7 presents a section of the helmet clip 3 with a focus on the rotation limiter. The helmet clip 3, herein shown in an assembled version, comprises herein a hollow portion 3A (as shown in FIG. 2), in which there is positioned the head 23 comprising a rotation limiter 24 of the helmet pin 22 having he delimiting protrusion 30 located at its top. A suitable form of the rotation limiter 24 is a tooth or a protrusion or more than one thereof engaging the delimiting protrusion 30.

[0127] For example, the rotation limiter 24 may limit the rotation at the amount of 80 to 90 degrees to either side. In a test embodiment, the angle was further limited to 45-55 degrees to either side. This value must be adjusted to a given kind of motor sport, depending on safe values for a driver as well as requirements of a given sport.

[0128] The head 23 is positioned inside the hollow portion 3A (as previously shown in FIG. 2) of the helmet clip 3, wherein the head 23 has a T-shape cross-section (vertically via its center). Around the vertical portion of the T-Shape, there is positioned the helical spring 25. Further, the head 23 comprises grooves for receiving the blocking balls 26. Additionally, the helmet pin 22 preferably comprises the circumferential groove 27 for receiving a clamp ring 28 comprising a suitable grip 29 of the clamp ring 28. Therefore, the clamp ring 28 locks the helmet pin 22 in the helmet clip 3.

[0129] In order to attach the helmet 5 to the helmet clip 3, the grip 29 of the clamp ring 28 must be held and the helmet pin must be pulled up, while positioning the helmet pin 22 in the head 23. The blocking balls 26 and the clamp ring 28 block self disconnection of the helmet 5 from the helmet clip 3.

[0130] In order to disconnect the helmet 5 from the helmet clip 3 the helmet clip must be pulled up.

[0131] The head 23 positioned in the helmet clip 3 may not rotate due to its protrusion (not shown on the drawing) engaging a cavity connected with the hollow portion 3A of the helmet clip 3.

[0132] FIG. 8 shows a variant of the helmet clip having a protective cap comprising an opening. The embodiment of the helmet clip 3 comprises a head 23 having a rotation limiter (elements 30 and 24 as shown in more details in FIG. 7) of the helmet pin 22.

[0133] The head 23 is positioned inside the hollow portion 3A (as previously shown in FIG. 2) of the helmet clip 3, wherein the head 23 has a T-shape cross-section (vertically via its center). Around the vertical portion of the T-Shape, there is positioned the helical spring 25. Further, the head 23 comprises grooves for receiving the blocking balls 26.

[0134] The helmet pin 22, preferably comprises a circumferential groove 27 for receiving blocking balls 26, and a clamp ring 28.

[0135] An opening 3B present in the top section of the helmet clip 3 is configured to receive a covering shield 31 having an opening 36.

[0136] In order to connect the helmet 5 to the helmet clip 3, one must pull the helmet clip 3 up while appropriately holding the head 23 with a finger placed in the respective opening 36.

[0137] In order to disconnect the helmet 5 from the helmet clip 3, one must pull up the helmet clip 3 and, with a rotational movement, move the arm 1 above driver's head. The arm 1 will rotate (pivot) on the carrying shaft 7.

[0138] A difference between the embodiments shown in FIG. 7 and FIG. 8 thus lies in different actions required to attach the helmet 5 comprising a respective helmet pin 22 to the helmet clip 3. Specifically, in the embodiment of FIG. 7 one needs to hold the grip 29 of the clamp ring 28 and pull up the helmet clip 3 thereby positioning the helmet pin 22 in the head 23. In turn, in FIG. 8 embodiment one needs to hold the head 23, with a finger inserted via the opening 36, and pull up the helmet clip 3.

[0139] FIG. 9 depicts a variant of the helmet clip comprising a spherical member 37 having two protrusions 41 and a full recess 42 in the helmet clip 3. The spherical member 37 is located at the top of the helmet pin 22 and is configured to engage a hollow portion 42 of the helmet clip 3.

[0140] The helmet pin 22 has, under the spherical member 37, a circumferential recess 38 configured to receive a spring clip 39. The helmet clip 3 has a cut out portion 40 for receiving the spring clip 39 so that the helmet pin 22 inserted inside the hollow portion 42 may be locked within. Once locked, the helmet pin may be disengaged by pulling out the spring clip 39 using its grip portion.

[0141] The spherical member 37 may further comprise two protrusions 41, preferably opposite each other, configured to engage the hollow portion 42 of the helmet clip 3 and to be inserted via guiding sections 43 present in the helmet clip 3.

[0142] In order to disconnect the helmet 5 from the respective helmet clip 3, one must pull out the spring clip 39 from the cut out portion 40 and with a rotational movement pull the arm 1 over driver's head. The arm 1 will rotate (pivot) on the carrying shaft 7.

[0143] The embodiment of the helmet clip 3, shown in FIG. 9, allows for freedom of movement of driver's head within a safe range.

[0144] FIG. 10 presents a variant of the helmet clip comprising a spherical member 37 having two protrusions and a partial recess in the helmet clip 3. The spherical member 37 has a top member 47 in a form of a disc having two opposite protrusions 48.

[0145] The helmet clip 3 has a partial cavity 44, in which the top member 47 is positioned, allowing a horizontal movement of the driver's head. The two opposite protrusions 48, restrict a rotational movement of the helmet pin 22 having the top member 47.

[0146] A difference between the full recess 42 in the helmet clip 3 (FIG. 9) and the partial recess in the helmet clip 3 (FIG. 10) is that the partial recess is configured to allow for a natural, horizontal movement (looking left/right) of a helmet 5 only while the full recess allows helmet 5 movements in all axes but restricted to natural head movement range of angles (for example by a use of appropriate protrusions). Thus, the embodiment of FIG. 10, in particular a connection between the helmet clip 3 and the helmet pin 22, is configured to facilitate a nodding movement.

[0147] The helmet pin 22 has, under the spherical member 37, the circumferential recess 38 (as shown in FIG. 9) configured to receive a spring clip 39. The helmet clip 3 has a cut out portion 40 for receiving the spring clip 39 so that the helmet pin 22 inserted inside the hollow portion 42 may be locked within. Once locked, the helmet pin may be disengaged by pulling out the spring clip 39 using its grip portion.

[0148] In order to disconnect the helmet 5 from the respective helmet clip 3, one must pull out the spring clip 39, from the cut out portion 40, and with a rotational movement pull the arm 1 over driver's head. The arm 1 will rotate (pivot) on the carrying shaft 7.

[0149] The embodiment of the helmet clip 3, shown in FIG. 10, allows for freedom of movement of driver's head within a safe range.

[0150] FIG. 11 shows an exploded view of the helmet clip with the helmet pin 22 having a cylindrically-shaped portion 45. The cylindrically-shaped portion 45 is located at the top of the helmet pin 22 and comprises two, preferably opposite, protrusions 46 for engaging two respective cavities present in the helmet clip 3 (not shown on the drawing). The protrusions 46 and the cavities limit the rotational movement of the helmet pin 22 having the cylindrically-shaped portion 45.

[0151] FIG. 12 presents an exploded view of the helmet clip 3 with the helmet pin 22 having a cylindrically-shaped portion 45, a disc top member 47 and two opposite protrusions 48 extending on the disc (as explained above, the number of such protrusions may vary). The disc top member 47 has preferably a lower diameter than the cylindrically-shaped portion 45.

[0152] The helmet clip 3 comprises, at its top, an opening with recesses 49 for receiving the disc top member 47 and the two opposite protrusions 48 extending on the disc top member 47. The protrusions 48 and the recesses, once engaged, limit the rotational movements of the helmet pin 22 having the cylindrically-shaped portion 45 with the disc top member 47.

[0153] The helmet pin 22 has, under the cylindrically-shaped portion 45, the circumferential recess 38 configured to receive a spring clip 39. The helmet clip 3 has a cut out portion 40 for receiving the spring clip 39 so that the helmet pin 22, inserted inside the hollow portion 42, may be locked within.

[0154] Once locked, the helmet pin 22 may be disengaged, from the helmet clip 3, by pulling out the spring clip 39, using its grip portion, from the cut out portion 40 and with a rotational movement pull the arm 1 over driver's head. The arm 1 will rotate (pivot) on the carrying shaft 7.

[0155] FIG. 13 depicts an exploded view of the helmet clip 3 with the helmet pin 22 having a cylindrically-shaped portion 45 and a bearing 50. The bearing 50 is positioned within the hollow portion 42 of the helmet clip 3, which is configured to receive a disc top member 47 of the helmet pin 22.

[0156] The disc top member 47 has preferably a lower diameter than the cylindrically-shaped portion 45.

[0157] The cylindrically-shaped portion 45, present underneath the disc top member 47, has two, preferably opposite, protrusions 46 for engaging two respective cavities present within in the helmet clip 3 (not shown on the drawing).

[0158] The protrusions 46 and the respective cavities, limit the rotational movement of the helmet pin 22 having the cylindrically-shaped portion 45 and the disc top member 47.

[0159] FIG. 14 shows an exploded view of the helmet clip 3 with the respective helmet pin 22 having a disc top member 47, the bearing and an opening for receiving a cap. In this embodiment, instead of the spring clip 39 there is employed a rod-like stopper 51.

[0160] In order for the rod-like stopper 51 to block the helmet pin 22 in the corresponding helmet clip 3, the disc top member 47 comprises a cavity 54 for receiving a portion of the rod-like stopper 51, wherein further the bearing 50 has, in its bottom portion, a horizontal through hole 53 (in a wall of its bottom section), matching the cavity 54. Therefore, the rod-like stopper 51, inserted via the cut out portion 40, passes via the horizontal through hole 53 and enters the cavity 54 thereby blocking the helmet pin 22 in the helmet clip 3.

[0161] The cut out portion 40, in which the rod-like stopper 51 is inserted, limits a rotational movement of the helmet pin 22 and allows for freedom of movement of driver's head within a safe range.

[0162] To this end, the rod-like stopper 51 may have a wider ending or a bent portion 51A, configured to operate as a grip portion, as shown in FIG. 13.

[0163] FIG. 15 shows an exploded view of the helmet clip 3 with the helmet pin 22 having a spherically-shaped portion 37 and an opening 55, in the top section of the spherical portion 37, for receiving a locking member 57. The opening 55, preferably has a horizontal diameter and receives the locking member 57 in a vertical direction (axis).

[0164] The spherically-shaped portion 37 further comprises at least one protrusion (preferably two, opposite each other) 41 for engaging respective at least one cavity present in the helmet clip 3 (not shown on the drawing).

[0165] The helmet clip 3, has in its top portion a substantially center opening 56 for receiving the locking member 57, which also engages the opening 55, in the top of the spherical portion 37.

[0166] The helmet pin 22 has, under the spherically-shaped portion 37, the circumferential recess 38 configured to receive a spring clip 39. The helmet clip 3 has a cut out portion 40 for receiving the spring clip 39 so that the helmet pin 22, inserted inside the helmet clip 3, may be locked within.

[0167] Once locked, the helmet pin 22 may be disengaged, from the helmet clip 3, by pulling out the spring clip 39, using its grip portion, from the cut out portion 40 and with a rotational movement pull the arm 1 over driver's head. The arm 1 will rotate (pivot) on the carrying shaft 7.

[0168] FIG. 16 presents a cross-section of the helmet clip 3 having an inserted helmet pin 22 comprising the spherically-shaped portion 37 with the disc top member comprising two opposite protrusions 48.

[0169] Two opposite protrusions 48 are preferred due to stability and equal distribution of forces, but there may be embodiments where the protrusions 48 are not opposite each other and where there is only one or more than two protrusions serving the same purpose.

[0170] The helmet clip 3 comprises an opening 49 (preferably having a horizontal diameter) with cavities for receiving the corresponding two opposite protrusions 48, which also act as rotation limiters of the helmet pin 22.

[0171] The helmet pin 22 has, under the spherical member 47, the circumferential recess 38 (as previously shown in FIG. 15) configured to receive a spring clip 39. The helmet clip 3 has a cut out portion 40 for receiving the spring clip 39 so that the helmet pin 22, inserted inside the hollow portion of the helmet pin 3, may be locked within.

[0172] Once locked, the helmet pin 3 may be disengaged by pulling out the spring clip 39, using its grip portion, from the cut out portion 40 and with a rotational movement pull the arm 1 over driver's head. The arm 1 will rotate (pivot) on the carrying shaft 7.

[0173] FIG. 17 depicts the helmet pin 22 mounted on the helmet 5. As previously shown in FIG. 2, the helmet pin 22 comprises the circumferential groove 27, for receiving a clamp ring 28, and has the delimiting protrusion 30 located at its top. The element pin 22 may be mounted on the helmet 5 using any techniques known in the art. In this embodiment the connection is not releasable.

[0174] FIG. 18 shows an embodiment of the present invention in which the helmet pin 22 is connected to a clamp 58 pivotably mounted on the helmet 5. This embodiment provides improved stability of the helmet 5 and may be releasable depending on the kind of the connection 59 of the clamp 58 to the helmet 5. In a preferred embodiment the connection 59 is made with rivets on left and right side of the helmet 5.

[0175] FIG. 19 presents an embodiment of the present invention in which the helmet pin 22 is releasably fixed 61 to a guide 60 connected to the helmet. A slider element 61 is fixed to the guide 60. This embodiment provides improved stability of the helmet 5 and is releasable.

[0176] FIG. 20 depicts the helmet clip 3 and the slidably-mounted element 2 in an embodiment comprising a four-teeth bolt 19. Additionally, the opening(s) 21 in the slidably-mounted element 2 also are corresponding four-teeth openings for receiving the four-teeth bolt 19. Preferably, the width of the teeth of the opening(s) 21 is greater than the width of the teeth of the bolt 19.

[0177] Further, the ear mount of the helmet clip 3 has its opening 20 with a plurality of teeth, e.g. 16. This arrangement allows for more flexibility when a nodding movement is concerned.

[0178] FIG. 21 shows the helmet clip 3 and the slidably-mounted element 2 in an embodiment comprising a protrusion 63 in a seat, of the helmet clip 3, located between the two ears comprising respective openings 21 being configured to receive the bolt 19.

[0179] The ear of the helmet clip 3 comprising the opening 20 also has a recess 62 corresponding to the protrusion 63 so that it may be engaged in an assembled state. As previously explained the bolt is received perpendicularly to the length of the longer section of the arm 1.

[0180] In this embodiment neither the openings 20, 21 nor the corresponding bolt 19 have any teeth.

[0181] FIG. 22 presents the arm 1 assembled on the carrying shaft 7 as previously shown in FIG. 2 as disassembled elements view. The carrying shaft 7 comprises a groove 9, in which one end of the spring element 10 is positioned.

[0182] The spring element 10 partly surrounds the carrying shaft 7 (preferably to the extent allowed by the hollow section in the mounting element) while the other end 10B of the spring element 10 adheres, with its flat surface, to the arm 1 between the two arms 8 as shown in FIG. 2. The flat surface acts like a spring thereby achieving the helmet's weight neutralizing function as explained with reference to FIG. 2.

[0183] FIG. 23 depicts a back view of the arm 1 assembled on the carrying shaft 7 wherein the helical springs 14 are fixed (for example anchored) to the arm 1 with their respective ends directed towards the arm 1. The other ends of the helical springs (the far ends) may be releasably fixed to the carrying shaft 7. Alternatively, other ends of the helical springs (the far ends) may be releasably fixed to respective left and right bushes 32 configured to receive the ends of the carrying shaft 7. In such an embodiment, the carrying shaft 7 does not comprise, at its ends, the threaded openings 7B, in which there may be positioned the threaded mandrels 11, as shown in FIG. 2. Instead, the threaded mandrels 11 are rather fixed to the left and right bushes 32 respectively.

[0184] FIG. 24 shows a bottom view of the arm 1 assembled on the carrying shaft 7 wherein the carrying shaft has energy absorbing elements 64 mounted thereon instead of the helical springs 14. The energy absorbing elements 64 may be made from a CONFOR foam.

[0185] FIG. 25 presents a lengthwise cross section of the arm 1 comprising bearings elements 18. The bearings elements 18 are preferably located on all four sides of the hollow portion of the longer section of the arm 1.

[0186] As already explained with reference to FIG. 2, there are bars comprising bearing elements 18 facilitating movement of the slidably-mounted element 2 within the hollow portion of the longer section of the arm 1.

[0187] Alternatively, between engaging planes of the arm 1 and the slidably-mounted element 2, there is a friction reducing agent, preferably a suitable lubricant or a Teflon layer.

[0188] FIG. 26 depicts a view of the arm 1 with a carrying shaft 7 being mounted in a bearing 65. The bearing 65 is mounted in the opening 6, positioned in an axis perpendicular to the length of the arm 1. The bearing 65 facilitates a more smooth pivot around the carrying shaft 7.

[0189] FIG. 27 presents a section of a formula car having the arm 1 connected to its chassis by means of an additional spring 66. The function of the spring is to allow easier release of the helmet clip 3 and keeping the opened arm 1 above the helmet 5 to avoid hitting the helmet pin 22 with an opened helmet clip 3. Further, the spring 66 compensates the weight of the device and the attached helmet 5, which as previously described allows for more comfort and makes it possible to use heavier and safer helmets 5.

[0190] FIG. 28 shows a section of a formula car having the arm 1 connected to its chassis wherein the arm 1 has an additional counterweight 67 with respect to vertical movements of the helmet 5. The purpose of the counterweight 67 is the same as in case of the spring 66.

[0191] Further, element 281 may act also as a blocking block for the device according to the present invention, in case the helmet is pushed downwards.

[0192] FIG. 29 depicts the arm 1 having an additional damping element 68 engaging the resistance block 4. Said damping element 68 decreases the pressure of the arm on the driver's head and eliminates rapid impacts of the arm 1 on the resistance block 4 in case of a collision of the helmet 5 with a flying object or hitting a safety fence by the formula car.

[0193] FIG. 30 presents an embodiment of the arm 1 having an I-shape. Atypical length of the arm 1 is first determined by the slidably-mounted element 2 and secondly by the construction of the formula car. Typically, the length will be greater than 10 cm but may extend beyond 20 cm. In a preferred embodiment the arm 1 has a length between 10 cm and 15 cm.

[0194] In this case the end of the arm, further away from the helmet clip 3, ends directly with an opening 6 for receiving the carrying shaft 7. Additionally, in this embodiment the bolt 19 connecting suitable elements (20, 21) of the slidably-mounted element 2 and the helmet clip 3 is not present and the slidably-mounted element 2 ends directly with the helmet clip. Such an embodiment further reduces the weight of the device.

[0195] FIG. 31 shows the device according to the present invention mounted on a shell 69 surrounding a driver's helmet 5 (when a driver takes a driving position) whereas the shell 69 is fixed to the chassis of the vehicle. Further, the arm 1 comprises a protective element configured to protect the helmet clip 3 from damage. FIG. 32 depicts the surrounding shell 69 comprising a resistance block 71. The resistance block 71 is the same as the resistance block 4 with a difference lying in the location of its mounting. The resistance block 4 is mounted on the chassis of the formula car while the resistance block 71 is mounted on the surrounding shell 69. In both cases the resistance block 4, 71 is configured to transfer energy into the chassis when the arm 1 hits the resistance block 4, 71 from above.

[0196] Preferably, in all embodiments, between engaging surfaces (of any two components such as the arm 1 and the carrying shaft 7) there is a friction reducing agent such as a suitable lubricant or a Teflon layer.

[0197] As evident from the embodiments shown above, the improved and cost effective Head and Neck Support And Protection device, also protects the head from impacts from the top as well as provides the support function.

[0198] During an impact of the attached helmet 5, for example with a debris from a crash, the present invention provides an improved protection by appropriately transferring forces from the elements impacting the helmet into the described device and further to the chassis of the vehicle.

[0199] In this way the forces acting on the helmet, and thus the head and neck of the driver, become neutral. By prohibiting or restricting head movement in x and y planes (i.e. parallel and perpendicular to the length of the vehicle's chassis) being implemented with springs, dampers as well as the protective pin 17, there may be used heavier helmets (having improved protection) the mass of which will be neutralized.

[0200] FIG. 33 presents a process of an impact of a wheel into the system according to the present invention. In such case the driver's helmet may only slightly move left-right as allowed by rotation limiters (within a safe range) or may move slightly downwards (for example in case of an embodiment shown in FIG. 29 (within a safe range).

[0201] In case of an impact into a safety fence, the slidably-mounted element 2, at the foremost end of which there is mounted the helmet clip 3 attached to a helmet 5, moves forward (in a linear fashion), together with the body of a driver in order to prevent injuries to the neck.

[0202] In the above case, then the head would be fixed in a given position, the neck could suffer an injury because the remaining parts of the driver's body would inevitably move while the head remains in a fixed position.

[0203] In turn, during side impact, the helical spring 14 will decrease forces acting on the head and will protect from injuries in such cases.

[0204] FIGS. 34A-B show a process of reaction of the system according to the present invention, to an impact into a safety fence. In FIG. 34B the slidably-mounted element 2 has extended, to its maximum allowed range, thus preventing injuries to the neck.

[0205] FIGS. 35A-C depict a process of installing and attaching a helmet to the system according to the present invention. This series of steps show an embodiment of the present invention presented with relation to FIG. 7.

[0206] In FIG. 35A, after a driver has taken a seat in the formula car, the device remains open (as shown in FIG. 1A) and a person (be it the driver or a support team member) holds the grip 29 of the clamp ring 28 with the index finger 351. Next, as shown in FIG. 35B, with the index finger 352 of the other hand and the thumb 353 one pulls the helmet clip 3 up, which results in loosening the blocking balls 26, present in respective openings in the head 23, that fall into the recess (see helmet clip 3 in FIG. 8) in the helmet clip 3.

[0207] In this manner the helmet pin 22 may be inserted into the helmet clip 3. The connection operates as a so called quick release system.

[0208] Lastly, as shown in FIG. 35C, the arm 1 is pulled downwards connecting the helmet clip 3 to the helmet pin 22 still holding the helmet clip 3 and the grip 29 as previously shown. Once the helmet clip 3 engages the helmet pin 22 the fingers, holding the respective elements, may be released. Then the blocking balls 26 are locked.

[0209] The system according to the present invention serves as protection from impacts into the helmet, limits head movements (e.g. in case of taking sharp turns with relatively high g values) as well as protects in case of impacts of the vehicle into for example a safety fence. Therefore, the invention provides a useful, concrete and tangible result.
