DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet-type helmet provided with detachable cheek pads on both left and right sides of a jet-type cap.

[0002]

2. Description of the Related Art A jet-type helmet of this kind is provided with a cushion made of a urethane material or the like disposed inside a shock absorbing liner formed of a cap body or styrofoam fitted inside the cap body. It is maintained by the repulsive elastic force of the member. In particular, the cushion member of the cheek pad that presses the jaw from the cheeks arranged on the left and right sides of the cap body greatly contributes to the fitting of the helmet, and when the helmet is worn, it comes into contact with the cheeks and the jaw. A restoring force due to the repulsive elastic force acts on the collapsed cushion member, and the restoring force causes the cushion member to come into close contact with both cheeks.

Conventionally, jet-type helmets include a type in which a cheek pad is detachable and a type in which the cheek pad is detachable.
It is conventionally known in Japanese Utility Model Publication No. 6-19530 by the present applicant. In the mounting structure described in this publication, a mounting plate for mounting a cheek pad is fixed inside the right and left sides of the cap body, and an engaging hole of the mounting plate is provided with an engaging projection of a base plate of the cheek pad so as to be detachable. It is made detachable by combining. Further, a gap is provided between the mounting plate and the inside of the cap body, and the gap is a projection space of the engagement projection projecting from the engagement hole, or a surplus space of the plate for correcting the shape of the cheek pad. It has become.

[0004]

Recently, a cheek pad 100 having a built-in cushioning material has been developed in order to improve safety for a wearer. (See FIG. 4) The cheek pad 100 is formed in a predetermined shape using the same material (polystyrene foam) as the cushioning material (shock absorbing liner) disposed inside corresponding to the head of the cap body 101. 102 and a cushion member 103 formed in a predetermined shape using a urethane material or the like are formed by laminating and adhering to a predetermined thickness. The function is used to improve the safety of the jet helmet.

However, such a cheek pad 100
In this case, since the cushion member 102 and the cushion member 103 have a two-layer structure, the thickness of the cushion member becomes thinner when considered as a helmet of the same size as compared with a cheek pad including only a cushion member as described in the above-mentioned publication. Therefore, it is inferior to the cheek pad described in the gazette in terms of wearing comfort. Conversely, if the cushion member 103 is made thicker by giving priority to the wearing comfort, the cushioning material 102 must be made thinner. Therefore, there is a possibility that the cushioning function may be deteriorated or may be erroneously bent and damaged at the time of attachment / detachment.

Therefore, it is conceivable to solve the above-mentioned problem by increasing the thicknesses of the cushioning material and the cushion member. However, simply increasing the thicknesses of both the cushioning material and the cushioning member makes it possible to reduce the thickness as compared with a helmet using a normal cheek pad. And the space inside the helmet becomes smaller. In other words, if the thickness of the cushioning material and cushion member is to be increased without reducing the space inside the helmet, it is necessary to make the size of the cap body larger than that using a normal cheek pad, It is undeniable that the weight increases and the appearance is not good. Also, when taking off and wearing the helmet, the wearer must spread the area around the cheek pad to the left and right and pass through the head, but the cushioning material 102 does not collapse,
There is a problem in that a margin for spreading can be secured only by the thickness of the cushion member 103, so that the cushion member 103 is hard to come off.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a jet-type helmet having improved safety without deteriorating good helmet wearing comfort and ease of taking off. Is to provide.

[0008]

The present invention employs the following technical means to achieve the above object. The technical means according to claim 1, wherein in a jet-type helmet in which cheek pads are detachably mounted on left and right sides of a jet-type cap, a cushioning material is disposed inside the cap, and an inner surface of the cushioning material is provided. A mounting plate having an engaging means for detachably mounting the cheek pad over the cheek pad is provided to secure a buffering function, and the mounting plate is formed of a low-rigid portion that can be deformed by compression. By directly fixing the cap to the cap via the contact piece, it is possible to prevent the mounting plate or the cushioning material from falling off during normal use or when attaching and detaching the cheek pad, and when receiving an impact The connecting piece is easily deformed so that the buffer function of the buffer material can be fully utilized. The engagement means includes everything that makes the cheek pad detachable from the mounting plate,
For example, there is a configuration in which the engagement means is configured such that the cheek pad can be attached to and detached from the attachment plate by fitting an engagement protrusion of the base plate in the cheek pad with an engagement hole of the attachment plate. By forming a concave portion facing the engaging hole on the surface of the material, the concave portion is secured as a projecting space of the engaging projection. The deformable connecting piece can be achieved by providing a low-rigidity portion, for example, by providing an inclined portion where force can easily escape, by reducing the thickness of the material, or by providing a large number of apertures.

According to the first aspect of the present invention, since the cushioning material for improving the safety of the helmet is disposed so as to be sandwiched between the inside of the cap and the mounting plate, the cushion is relatively positioned on the cap body side. The buffer function is secured. Further, since the mounting plate is directly fixed to the cap via a connecting piece formed of a low-rigidity portion that can be deformed by compression, the connecting piece is easily compressed and deformed when subjected to an impact, so that the cushioning is cushioned. Since the cushioning function of the material is fully utilized and the mounting plate is fixed with the cushioning material interposed therebetween, the mounting plate or the cushioning material is prevented from falling off during normal use or when attaching and detaching the cheek pad, In addition, the required adhesion is minimal and contributes to the simplification of the assembly process. And since the cushioning material is arranged using the gap between the inside of the cap body and the mounting plate which has existed conventionally, an increase in the distance from the inside of the cap body to the mounting plate is necessary compared to the conventional one. Minimized.
