DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0030] FIG. 1 shows a motorcyclist helmet 1 according to the prior art. The helmet shown is typical in its structure and is made substantially of three layers: an exterior rigid plastic layer 10, an intermediate energy absorbing soft layer (not shown), typically made of a foamed polystyrene (EFS), and a textile layer 11 which is made soft for the user convenience, such as for absorbing sweat, adaptation to the shape of the user head, etc. The shapes of the layers are specific to each helmet, resulting from safety, aerodynamics, and aesthetic considerations. In order to accept a Bluetooth headphones device 20, some helmets are provided with a helmet cavity 15. In said preferable cases, The helmet cavity is made of plastic, and it extends through or from the rigid exterior layer 10, and through the intermediate layer. In such preferable cases, the helmet cavity further includes an electronic connector 18 for enabling connection between a headphones device and earphones that are located internally within the intermediate layer and the internal layer 11. In some other less preferable cases, the earphones are not pre-installed within the helmet, and they are connected and attached by the user externally.

[0031] As shown, the helmet cavity 15 has a shape to accept a specific Bluetooth device 20 of one specific model. The Bluetooth device 20 must conform to the helmet cavity 15, also in terms of the location of the connector 18, and it typically has locking means (not shown) for holding the device safely in place within the helmet cavity. Any device having a shape and/or connector which differs from the structure as provided within the helmet cavity, cannot be accommodated at the cavity, nor can it appropriately operate.

[0032] FIG. 2 shows an adaptor 30 for enabling insertion of devices of various shapes into a helmet cavity of a given shape. FIG. 3 shows a rear view of said adaptor according to an embodiment of the invention. The adaptor 30 is typically made of plastic, and it is a two-level component. The lower level 17 of the component has a shape which substantially conforms to the shape of helmet cavity 15, and therefore it can be inserted into this cavity. Locking means (that are not shown in the figure) safely locks the lower level 17 of the adaptor 30 within the helmet cavity 15, while a higher level 16 of the adaptor protrudes from the level of the exterior layer 10, such that it can substantially have a larger or smaller periphery compared to the periphery of helmet cavity 15. The higher level 16 of adapter has an adapter cavity 19, which is adapted to accept the specific Bluetooth device 20, and therefore the shape of said adapter cavity 19 conforms to the shape of the specific device 20. In one embodiment, the adaptor 30 comprises a first connector (not shown) at the lower level 17 which is adapted for mating with connector 18 at the helmet cavity 15, and a second connector 26 at the higher level 16 for mating with a corresponding connector at the device 20. Optionally, wires may be provided to bridge between the contacts of said two connectors of adaptor 30. In another embodiment, the adaptor 30 has an opening (not shown) through which a single connector mates in one of its sides to the cavity connector, and in its opposite side to the headset.

[0033] The adaptor also comprises locking means at the higher level 16 for locking the device 20 within adaptor cavity 19.

[0034] The adaptor may optionally be provided with an antenna (not shown), which is connected to the device 20 via a connector at the higher level 17.

[0035] As shown, the adaptor 30 of the present invention enables connection of a device 20 having any shape to a helmet cavity 15 within the helmet 10 which is designed to accept a headphones device having a corresponding specific shape. As shown, only the lower level of adaptor 30 has to conform to the shape, and dimensions of helmet cavity 15, and to the connector 18 within the helmet. The upper level of the adaptor and the adaptor cavity 19 are designed to conform with the shape, dimensions, and connector of the specific headphones device 20. The adaptor is preferably designed to conform to the shape of the helmet, taking into account, among other considerations, also aerodynamics considerations.

[0036] FIG. 4 shows still another embodiment of the invention. The adaptor 130 is similar in its structure to the adaptor 30 of FIGS. 2 and 3. Elements in FIG. 4 having similar numeral indication to those of FIGS. 2 and 3 also perform similar functions respectively; therefore, the description with respect to those elements will not be repeated. The adaptor 130 comprises an opening 141, through which the connector 118 enters to mate with a respective connector of the headset 120. The adaptor 142 also comprises clamping means 142 for attaching it with a corresponding arrangement at the cavity 115. The helmet 10 comprises one or more additional cavities 149, for containing other components that are irrelevant to the present invention (such as speakers).

[0037] Therefore, the adaptor which is typically of low cost, simple, and replaceable, provides to the manufacturer of the helmet the freedom with respect to adaptation of the helmet to headphones devices of various shapes, while it also provides the manufacturer of the Bluetooth device the freedom with respect to adaptation of the device to helmets having a helmet cavity of any shape and dimensions. Moreover, devices of various shapes can be easily attached to a given helmet, as long as a suitable adaptor 30 is used.

[0038] Therefore, for a given helmet, another adaptor 10 may be necessary for each different headset model. Furthermore, for each device model, another adaptor 10 may be necessary for each specific helmet model. Therefore, when a user wishes to replace a headphone device, he does not need to buy a new helmet with a suitable helmet cavity. Moreover, when the user wishes to replace the helmet, he does not have to have to worry whether this helmet will adapt to his existing headphones device. In both of said cases, only a suitable cheap and simple adaptor has to be replaced.

[0039] In one embodiment of the invention, when a need is arisen to remove the headphones device from the helmet, the device 20 is detached from the cavity 19 of adaptor 30, while the adaptor 30 remains attached to the helmet 10 within the helmet cavity 15. In another embodiment, the adaptor 30 may be detached from helmet cavity 15 together with the headphones device 20 which remains within the adaptor cavity 19. The gripping means within the helmet to attach to the adaptor 30 to the helmet, and within the adaptor to attach the adaptor both to the helmet and to the device 20 are standard, and may be of various types.

[0040] While some embodiments of the invention have been described by way of illustration, it will be apparent that the invention can be carried out with many modifications variations and adaptations, and with the use of numerous equivalents or alternative solutions that are within the scope of persons skilled in the art, without departing from the spirit of the invention or exceeding the scope of the claims.
