A full-face crash helmet with an improved chin-covering member

Abstract

 A crash helmet (1) of the full-face type is provided with a chin-covering closure body (4) having an inner padded chinrest body (6) the position of which is adjustable with respect to the chin-covering closure body (4) but which can be fixed in the selected position once adapted to a given user.

Description

[0001] The present invention relates to a crash helmet of the so-called "full-face" type, incorporating a chin-covering member having means able to guarantee a comfortable and close fit to the chin of the user.

[0002] Crash helmets for motorcyclists, including those of the type entirely enclosing the user's head, known as "full-face" helmets, are normally fixed to the head of a user by means of a chin strap which is provided with an adjustable buckle which allows the mutual connection of its ends at the desired length to hold the helmet in place securely and without wobbling. By adjustment of this strap such helmets can in practice be easily adapted to any shape of head and in particular, to the length and shape of the chin.

[0003] Recently, an improvement to the known full-face crash helmet for motorcyclists has been introduced; these crash helmets are still of the full-face type, but instead of a chinstrap they have a lower shaped element or "body" which is hinged to the helmet and can be turned downwardly to vary the size of the lower opening of the helmet through which the wearer's; head is introduced. When this body is in the closed position the lower opening is of smaller dimensions than those of the head of the user so that, manifestly, the helmet cannot come off; on the other hand, when the body itself is in the open position it is possible easily to remove the helmet from the head or to put it on. Consequently such helmets do not need the conventional chinstrap because the securing action is effectively exerted by the said body.

[0004] However, this body has to be padded internally with soft material for comfort of the wearer, this padding being in a form conveniently to surround the chin of the wearer, and because of the presence of the padding it is not always possible for the helmet to be securely fixed to the head of the wearer, bearing in mind the wide range of head shapes which have to be accommodated.

[0005] In fact, although the body is structured in such a way as to prevent the helmet form coming off the head of the wearer it cannot be shaped in a "universal" way to fit any form of chin or to fit the overall dimensions of all head shapes on which it may be worn. In other words, this construction is able solely to prevent the helmet coming off accidentally, but not to avoid the troublesome possibility of it moving loosely with respect to the head during use, even if correctly fitted and with the body closed.

[0006] The object of the present invention is that of eliminating the disadvantages discussed by providing a crash helmet of the full-face type which is formed in such a way as to be able to be fixed to the head of the wearer in a secure manner without wobbling loosely, when properly adjusted.

[0007] According to the present invention there is provided a crash helmet of the full-face type having a rigid hinged closure body for covering the chin of a wearer characterised by the fact that this closure body carries a padded inner chinrest body the position of which is adjustable with respect to the closure body on which it is carried, whereby to be adaptable to the shape of the chin of a wearer.

[0008] A particular advantage of the present invention is that it provides a crash helmet of the full-face type, which can be adapted, within wide limits, to any shape of chin or head and can be fitted securely thereon, once properly adjusted, simply by closure of the hinged body.

[0009] Another advantage of the present invention is that it provides a crash helmet of the full-face type, which will not be subjected to any vibrations during use, whatever the activity of the wearer and however rigorous his movements may be.

[0010] One embodiment of the invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which:

Figure 1 is a schematic side view of the helmet of the invention, with the hinged body in the closed position;

Figure 2 is a side view of the same helmet with the hinged body in the open position;

Figure 3 is a schematic side view of the hinged body; and

Figure 4 is a section of the hinged body taken on the line IV-IV of Figure 3.

[0011] With reference now to the drawings the full-face crash helmet shown is generally indicated with the reference numeral 1, and comprises a cap portion 2 of substantially conventional type with a transparent visor 11, a lower opening 5 defined in part by a chin protector 3, to which is pivoted a hinged chin-covering closure body 4.

[0012] This chin-covering closure body 4 has the shape of an enclosing shell which can be disposed beneath the chin of the user in such a way as conveniently to reduce the dimension of the lower opening 5 of the helmet itself, and is preferably made of a plastics material or a reinforced plastics material. Connected to the chin-covering closure body 4 is an inner chinrest body 6 which is provided with shaped padding which can adapt itself to the shape of the chin of the user. To form this attachment the inner face of the lateral part of the chin-covering closure body 4 is provided with respective projections 7 with a guide function having a slot 12 capable of housing a fixing screw 8. The inner chinrest body, in turn, has a corresponding channel 9 formed in proximity to the said guide projection 7 and provided with at least one threaded hole which can engage the fixing screw 8. Consequently, the closure body 4 and the chinrest body 6 can be adjusted relative to one another by sliding movement of the chinrest body 6 along the guide projections 7 within the range determined by the length of the slot 12 along which the fixing screw can slide.

[0013] A resilient fixing member generally indicated with the reference numeral 10 is provided on the helmet and can be fixed on both sides to the base of the chin-covering closure body 4 to hold this in the closed position. With the closure body 4 in the open position the user can introduce his head into the helmet: the closure body can then be closed and by adjusting the position of the inner chinrest body by trial and error a firm connection of the helmet to the head itself can be obtained by bringing the inner chinrest body to a suitable position against the chin. It will be appreciated that the chinrest body, like the remainder of the interior of the helmet, is suitably padded so that firm pressure can be exerted without discomfort.

[0014] The available diretion of relative movement of the chinrest body 6, and the padding thereof, are designed in such a way as to allow the adaptation of the helmet to the greatest possible range of head shapes. Moreover, once the said fixing screw 8 has been tightened (when a suitable adjustment has been found) relative sliding between the closure body 4 and the inner chinrest body 6 will not occur even in the case of impact.

Claims
