(15) FIG. 14 is a perspective view of the sliding mechanism of the display for the helmet according to the invention;

(16) FIG. 15 is a partially sectional plan view from below of the mechanism shown in FIG. 14.

(17) With reference to the figures, the helmet according to the invention, generally designated by the reference numeral 1, comprising a helmet shell 2 that constitutes the body of the helmet, to which a video acquisition device 3 is applied which can be constituted by a front video camera, or by a rear video camera, or by a pair of video cameras or more.

(18) The video acquisition device is powered by a battery pack 4 that is arranged at the rear part of the helmet and is coupled to the shell 2 of the helmet itself.

(19) The helmet has, moreover, a visor portion 5 to which a display 6 is coupled. The visor portion is extended preferably beyond the position of the video acquisition device 3.

(20) The connection between the video acquisition device 3 and the display 6 is entrusted to a connection 7 (wired, as in the figure, or wireless).

(21) One of the particularities of the invention resides in that the display can be moved from an active position, such as the one shown in FIGS. 1, 2 and 3, to a partially active position, as shown in FIGS. 4, 5 and 6, to a position that is still a partially active position but different from the previous position, shown in FIGS. 7, 8 and 9.

(22) The display 6 is provided with means that allow its adjustment from an active position, as shown in FIGS. 1, 2 and 3, to a frontally raised position (totally unhindered direct viewing field) to a position in which the display is moved laterally with respect to the position of FIGS. 1, 2 and 3 (with fixed focus for the right eye), as shown in FIGS. 4, 5 and 6, finally to a position, as shown in FIGS. 7, 8 and 9, in which the display is moved laterally and angled so as to leave the viewing field completely unhindered (with variable focusing distances for the right eye).

(23) As shown in FIGS. 10, 11 and 12, the display, in addition to being moved laterally and angled, can also be rotated upwardly, both in the position in which the display is arranged in front of the eyes and in the position in which the display is moved laterally, and finally in the position in which the display is moved laterally and angled.

(24) The means for adjusting the position of the display 6 comprise a first guide and a second guide. In particular, the display 6 is provided with a guide 10, which is substantially C-shaped and is connected in an upward region to the display 6.

(25) The display 6 can rotate with respect to the guide 10 by pivoting about pivots 11 that protrude toward the inside of the short portions of the C-shape.

(26) The guide 10 is adapted to mate with a guide 12 provided at the lower edge of the visor portion or front piece 5 of the helmet.

(27) The guide 12 is provided with blocking means 13 adapted to engage a tooth 14 arranged at one end of the guide 12, so as to move the guide 12 to overlap the guide 10 perfectly when the display has to be in the active condition in which it is completely arranged in front of the eyes of the operator. Moreover, rubber washers are present so as to create a block against unintentional rightward sliding of the display.

(28) The sliding of the display 6 connected to the guide 10 is entrusted to a coupling between a slot 15 defined on the lower surface of the guide 12, i.e., the surface designed to face the guide 10, and a protruding pin 16 defined on the upper surface of the guide 10, surface which is intended to face the slot 15 of the guide 12.

(29) FIG. 15 shows the rotated condition of the guide 10 with respect to the guide 12 coupled to the helmet. FIGS. 14 and 15 show only the system of guides for the sake of simplicity. In this position, the slot 15 descends for a few millimeters in a seat of the guide 13 provided expressly so that, merely by way of the weight of the display, it is in practice locked in the 45 position, in practice blocking the counter clockwise rotation. By way of a slight manual lifting of the display and of the guide 10 anchored thereto, the slot 15 exits from the seat that blocks its rotation and therefore allows the display to rotate counterclockwise in order to bring the guide 10 back in axial alignment with the guide 12.

(30) In all the positions of the display, said display can be rotated upwardly.

(31) The helmet described above allows therefore to have a display that can be arranged according to the requirements of the user, completely in front of the viewing field, or moved laterally thereto, or moved and angled so as to have the viewing field completely unhindered.

(32) The possibility to have the display moved laterally and angled allows the brain not to have a single focusing distance, since the display is angled, and the points of interest can be at a different distance from the eye, and therefore an automatic process is not established by which the brain changes focus automatically, switching between close up and distant, with consequent eye fatigue.

(33) In practice it has been found that the helmet according to the present invention achieves fully the intended aim and objects.

(34) The helmet thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

(35) Thus, for example, the movement of the display can be motorized.

(36) All the details may further be replaced with other technically equivalent elements.

(37) In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements and to the state of the art.
