DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a full face type or jet type helmet worn on the head when riding a motorcycle or a motor vehicle, and more particularly, to an internal body which stably supports the helmet against the head. About helmets.

[0002]

2. Description of the Related Art Generally, a full-face type or jet type helmet worn on the head when riding a motorcycle or an automobile is, as shown in FIGS. And a shock-absorbing liner 20 made of styrene foam or the like fitted and mounted inside the cap body 19, and a cushion body 2 attached inside the shock-absorbing liner
1, or an interior such as a cheek pad 22 or an ear cup 23 which is detachably provided inside the cap body.
And in the case of the above-mentioned helmet premised on use at high speed running, important functions required for the interior such as teak pads and ear cups installed inside the cap body,
Even when various forces due to the flow of air are applied, the head is firmly pressed to maintain a constant position relative to the wearer's head, thereby preventing the helmet from sticking.
Furthermore, even if the helmet is pushed from the front by high wind pressure during high-speed running, the inner face of the chin guard can be supported in the full face type, and the inner face of the shield in the jet type with shield can be supported so as not to be too close to the nose and mouth. Important for the interior.

[0003]

The basic structure of the structure in which the interior supports the helmet is based on the inner surface of the cap or the inner surface of the shock-absorbing liner on the inner side of the cap, via the soft cushion material disposed therethrough, and the wearer's head. By holding down the part. Therefore, considering the direction of the force that adds the ability that the interior can cope with, the force applied in the direction perpendicular to the surface of the head can be firmly dealt with, but the direction of the force is far from vertical. It is natural that the ability to cope with this will decrease. However, the interior of a full face type or jet type helmet supports the force applied from the front by responding by holding down the forehead and cheeks,
Considering the inner shape of the shock absorbing liner, the forehead is the only part that can receive the force from the front at an angle close to vertical. Also, as shown in the full face type helmet of FIG. 9 and the jet type helmet of FIG.
Cheek pad 22 for full face helmet
And earcups 23 for jet-type helmets
Although it also holds down the cheeks, the efficiency of the force applied from the front is low because the direction of the force is significantly different from the direction in which the inside of the cap or the shock absorbing liner presses the head.

[0004] Therefore, as a means for compensating for the low efficiency, the cheeks should be pressed tightly with a hard cushion material.
In the case of the full face type, the cushion material is stretched forward and pressed down near the mouth. However, such coping techniques impair wearability and comfort. When the wearer's head is divided into parts, the effective part for supporting the force applied through the cushioning material is a part having a bone directly under the skin. From that point of view, the portion other than the forehead that is effective for supporting the force from the front is narrowed down to the cheek. The area around the lower jaw may be effective, but holding it down is limited by the shape of the helmet and is problematic.

[0005] The part of the cheekbone is located near the center of the force applied to the helmet from the front by the wind pressure, and is a part where the user does not feel any pain even if pressed strongly.
It is an effective place to support force from the front. Therefore, a projection is provided on the inner surface of the helmet that goes inward along the cheekbone, and the periphery of the cheekbone is pressed at an almost vertical angle by the inner surface of the projection via a cushioning material arranged between the face and It can support power efficiently.
However, providing a hard projection on the inner surface of the cap may damage the head, face, and the like when subjected to a strong impact, and is also prohibited by major helmet standards.

[0006] The present invention has been made in view of the above-mentioned problems of the prior art.
An object of the present invention is to provide a helmet having an interior that can stably support the helmet even when the helmet is pushed from the front by high wind pressure during high-speed running.

[0007]

The technical means taken by the present invention to achieve the above object has a hardness sufficient to support a common sense force applied from the front by wind pressure during traveling. In addition, when a stronger force is applied, the support part, which has flexibility and appearance shape that will not easily damage the head and face by bending easily, etc., goes around the front of the cheekbone and the front of the face along the cheekbone Thus, there is provided a helmet having an interior provided with a structure provided inside a cap body or inside a shock absorbing liner, and configured to hold down a cheekbone portion via a cushion material disposed inside a support portion thereof.

[0008] Helmets to which the present invention is directed are:

As the inner body, a cheek pad corresponds to a full face type helmet, and an ear cup corresponds to a jet type helmet.

Therefore, the above-mentioned supporting portion may be formed integrally with the cheek pad of the inner body in the case of a full face type helmet, or may be formed integrally with the ear cup of the inner body in the case of a jet type helmet. Of course, it goes without saying that the inner body other than the teak pad and the ear cup may be formed.

[0010] The above-mentioned supporting portion has a protruding amount which goes around the front of the face along the cheekbone, and may be of a fixed type in which the protruding amount of the supporting portion is fixed to a predetermined amount, or a contour of the face of the wearer. Any of the variable types that can adjust and change the amount of protrusion to an optimum state according to the conditions. When the support portion is of a variable type, the support portion is in a state of maximum protrusion before the helmet is put on the head, the helmet is put on in this state, and after the helmet is put on the head, the support portion is attached to the cheekbone. Move to the contact position.

According to the above-mentioned means, since the shock absorbing liner or the inner body on the inner side of the cap body is provided with the support portion of the cushion body which is formed so as to go around the cheekbone to the front of the face along the cheekbone. If the cheekbone portion is pressed at a nearly vertical angle via the cushioning material arranged on the inner surface of the support, the force from the front can be efficiently supported, and the wobble of the helmet can be prevented.

On the other hand, the slider 9b has a sawtooth-shaped engaging portion 17 arranged on the surface of the band portion 16 along the longitudinal direction, and a support portion 18 is integrally bent at a side end of the band portion. Therefore, when the support portion 18 is variably adjusted, first, the slider 9b is pulled out as shown in FIG. 7 before putting on the helmet, and after putting on the helmet, the slider 9b is pushed in so that the support portion 18 is brought into front of the cheekbone. The adjustment is completed by contacting the side.

In each of the above-described embodiments, the support portion that wraps around the front of the face along the cheekbone from a position almost directly beside the cheekbone has a hardness sufficient to support the force of common sense applied in normal use. The head is bent when a further force is applied, and a member having flexibility without fear of damaging the face, such as a base plate formed of a resin flat plate, has been described. When a force is applied, the cushioning member may be formed of a shock absorbing member equivalent to a shock absorbing liner that does not damage the head and face by being crushed. Of course, the same function and effect can be exhibited. Needless to say.

[0021]

According to the safety helmet for riding of the present invention, the support portion protrudes forward of the cheekbone and the portion of the cheekbone is provided through the cushion body disposed on the inner surface of the support portion. Since it can be held down, the force applied to the helmet from the front by the wind pressure can be efficiently supported without impairing the wearability and comfort. Therefore, it is possible to provide a stable helmet free from glaring while keeping the relative position with respect to the wearer's head constant. In the case where the support portion is provided on a detachable cheek pad or an ear cup provided on the inner side of the cap body according to the configuration of claims 2 to 5, each of the support portions is replaced by replacing the cheek pad and the ear cup. It is possible to establish a support structure that suits the needs. Further, according to the configuration of the sixth aspect, since the support portions provided on the cheek pad and the ear cup can be variably adjusted, the wearer can adjust and use the optimal state.
