If desired, the helmet 10 may be provided with left and right ear covers for protecting the ears of the wearer.
The front and rear portions 12, 14 (front and rear shells 16, 18 more particularly) can move one with relation to the other so as to adjust the size of the head receiving cavity of the helmet 10. Left and right locking mechanisms 50, 52 retain the front and rear portions 12, 14 in the position selected by the wearer. Any suitable type of locking mechanisms can be used without departing from the spirit of the invention.
In operation, a wearer who puts on the helmet 10 and realizes that it is too large or too small, does not need to remove the helmet 10 to adjust it. The wearer must simply release the locking mechanism 50, 52 expand or contract the size of the helmet 10 by displacing the front and the rear portion 12, 14 in relation to each other in the appropriate direction.
Alternatively, helmet 10 may comprise a non-adjustable one-piece shell covering a one-piece inner pad and a one-piece comfort liner. In another possible variant, the helmet 10 may comprise separate front and rear portions 12, 14 that are connected to one another in any suitable way but not adjustable one relative to the other.
The rear shell 18 comprises left and right elongated slots 40, 42, positioned symmetrically about a longitudinal axis of the helmet 10. In the example provided, left and right elongated slots 40, 42 extend perpendicularly to the longitudinal axis of the helmet 10 along the base of the rear shell 18. As shown on
The occipital inner pad 54 faces the occipital region OC of the head, the occipital inner pad 54 being movable between the first position shown in
The occipital inner pad 54 may be made of expanded polypropylene (EPP) or expanded polyethylene (EPE) or polyethylene foam or polyethylene foam having two different densities. Other materials can also be used without departing from the spirit of the invention. The occipital inner pad 54 may comprise a rear portion 58 facing the inner surface 96 of the rear shell 18 and a front portion 59 for facing the occipital region of the head. The front portion 59 has an inner surface 56 and may be less rigid than the rear portion 58. The inner surface 56 may have a ribbed pattern and may be made of a soft absorbent material while the rear portion 58 may be made of a rigid plastic-like material or equivalent. Optionally, one or more comfort liners may be affixed to the inner surface 56, by any suitable means.
As shown, the central member 62 is an elongated piece extending along the longitudinal axis of the helmet from an upper part 64, that is hingely mounted with respect to the rear shell 18 (e.g. to the rear central inner pad 24 as best shown in
As shown on
Left and right wedging members 44, 46 may comprise a locking mechanism which can be any suitable mechanism for preventing unintentional movement of the left and right wedging member 44, 46. In the example provided, the locking mechanism comprises a series of protrusions 118 provided on the support 108 adapted to engage the matching series of notches 48 provided on the inner surface 96 of the rear shell 18.
The helmet 10 also comprises respective actuators 102 that are connected to the respective wedging members 44, 46 and are accessible to the wearer for moving the left and right wedging members 44, 46. Each actuator 102 comprises a post 112 extending from a button 106 through the elongated slot 40; 42 to the support 108 of the wedging member 44; 46. A biasing element 114 is provided that pushes the button 106 away from the outer surface 98 of rear shell 18. As a result, the post 112 pulls the support 108 towards the inner surface 96 of rear shell 18 and holds the support 108 in the lock position. When the button 106 is pushed towards the rear shell 18, the biasing element 114 is compressed and the support 108 is pushed away from the inner surface 96 of the rear shell 18, thus disengaging the protrusions 118 from the notches 46 and allowing the wedging member 44; 46 to be moved along the elongated slots 40; 42. In the example provided, the biasing element 114 is a spring mounted on the post 112, however any other suitable biasing means could be used.
In the example provided, the actuator 102 has a receptacle 104 for encircling the button 106. The post 112 passes through a hole in the base of the receptacle 104 and two guide bars 116 protrude from the support 108 through the elongated slot 40; 42 and through one or more holes in the base of receptacle 104. The guide bars 116 serve to prevent the rotation of the receptacle 104 about the axis of post 112. The guide bars do not extend so far as to impede the depression of actuator 102. Advantageously, the button 106 is always at least partially contained within the receptacle 104 and thus is also kept from rotating about the axis of the post 112 by the receptacle 104 that is anchored by the guide bars 116. Furthermore, the biasing element 112 is between the button 106 and the base of the receptacle 104 and thus does not touch the outer surface 98 of the rear shell 18. Instead the receptacle 104 acts as a skid plate of the actuator 102 and biasing element 112. It should be noted that although two guide bars 116 are shown here, more than two or only one guide bar 116 could also be used. Furthermore, neither guide bars 116 nor receptacle 104 are necessary, but merely useful in preventing rotation of the button 106 about the axis of post 112.

As seen in
As mentioned above, the occipital inner pad 54 may comprise a base portion 58 and a pad portion 59. The base portion 58 is rigid so that movement of the left and right wedging members 44, 46 outwards does not easily deform occipital inner pad 54 but rather pushes it forwards towards the occipital region OC. The base portion 58 may have a channel 160 dimensioned to accommodate the wedging members 44, 46. The pad portion 59 is made of padding material for comfort and protection of the occipital region.
The present invention provides the user of helmet 10 with an easy and convenient way to adjust the occipital inner pad 54. The left and right wedging members 44, 46 are moveable via actuators 102 to adjust the position of occipital inner pad 54 while the helmet 10 is being worn. A locking mechanism which may be provided on respective supports 108 of the left and right wedging members 44, 46 prevent the unintentional displacement of the left and right wedging members 44, 46.
The above description of the embodiments should not be interpreted in a limiting manner since other variations, modifications and refinements are possible within the spirit and scope of the present invention. The scope of the invention is defined in the appended claims and their equivalents.
