Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mounting structure for an ear cushion mounted on a jet helmet.

(Prior Art) In a jet helmet having an ear cushion,
The ear cushion is generally fixed to the inside of the helmet cap with screws or rivets.

Therefore, in the size adjustment performed when purchasing a helmet, it is almost indifferent to the fact that the ears fit or not fit, and it is the actual situation that a helmet with tight ears or a helmet with a loose ear is used with patience. is there. Also, since the ear cushion comes into direct contact with the skin, the degree of dirtiness is very large, but it cannot be washed or replaced because it is fixed as described above.If the dirt is severe, wipe it with a cloth. ing.

Therefore, recently, an ear cushion that can be attached to and detached from a cap body has been proposed as Japanese Utility Model Laid-Open No. 62-70130.

(Problems to be solved by the invention) In the above-mentioned Japanese Utility Model Laid-Open No. 62-70130, the ear cushion is attached to and detached from the inner surface of the cap by using a velvet fastener, and therefore, is attached to the cap body. Even in the state, there is a problem that the ear cushion is likely to have a grit, and it is difficult to obtain a stable fit like the conventional fixed type.
In addition, the velvet fastener for attaching and detaching the ear cushion has a problem that thread debris is entangled by washing and the curl portion at the tip is deformed, so that the degree of engagement is weakened.

The present invention has been made in view of the problems of the above-described conventional technology. The purpose of the present invention is to obtain a fitting feeling equivalent to that of a fixed ear cushion, and to attach and detach the washing means. It is to provide a mounting structure that can withstand long-term use without being damaged by.

(Means for Solving the Problem) In order to achieve the above object, the ear cushion mounting structure according to the present invention has a mounting base plate formed of synthetic resin fixed to an ear cushion mounting portion on the inner side of a cap body of a helmet. , The mounting base plate is provided with a claw receiving groove into which a positioning claw projecting on the back surface of the ear cushion body is fitted, and a through hole into which a hooking projection is fitted and engaged, so that the ear cushion body is detachable. And

It is effective to provide at least two engaging projections projecting from the through holes of the mounting base plate and the base plate of the ear cushion body, and to provide them on both sides of the ear cushion body having a substantially U-shaped front surface.

(Function) According to the above means, the ear cushion body is stabilized by the engagement of the positioning claw and the claw receiving groove, and the engaging projection and the through hole with the mounting base plate fixedly fixed to the inside of the cap body with the screw or the rivet. It is well engaged and held, and the base of the ear cushion body is rolled up to release the engagement with the mounting base plate and can be removed.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. In the figure, A is a jet type helmet, and an impact absorbing liner is provided inside a cap body 1 formed of a material such as FRP. It is fitted and fixed, and the wearing body 2 such as a head cushion and a head band is attached to the inner surface of the shock absorbing liner, and the ear cushion body 3 and the jaw band 4 are attached.

The ear cushion body 3 is attached to the cap body 1 by using a rivet 6 to which a chin band 4 is fixed to an ear cushion mounting portion 1a inside the cap body 1 by a mounting plate 5 having a substantially triangular front face formed of synthetic resin. In addition to being fixed, the projecting piece 5'protrudingly provided on the peripheral edge of the mounting base plate 5 is inserted and fixed between the cap body 1 and the shock absorbing liner.

A claw receiving groove 7 is formed at a top position of the mounting base plate 5, through holes 8 and 8'are opened at left and right corner portions, and a central portion excluding the left and right corner portions is outside. The ear fitting portion 9 is formed so as to be bulged in one direction. Also, the ear fitting portion 9
The jaw band 4 described above is fixed to the portion with a rivet 6.

The ear cushion body 3 which is engaged with and disengaged from the mounting base plate 5 is a substrate 10 formed of a synthetic resin flat plate in a substantially U-shaped front face, and the substrate thereof.
Cushioning material 11 such as polyurethane foam with coarse mesh and good air permeability placed on 10 and lining cloth covering them
The lining cloth 12 is made of a material which is fixed to the substrate 10 by means such as thermocompression bonding. Further, on the back surface of the substrate 10, positioning claws 13 which are fitted in the claw receiving grooves 7 and engaging projections 14 and 14 'which are fitted and engaged in the through holes 8 and 8'are integrally formed. The positioning claw 13 has a substantially L-shaped cross section, and an undercut-shaped engaging portion 15 is formed on the outer surface of the upper end of the rising piece so that the hole edge of the claw receiving groove 7 is hooked.

On the peripheral edge of the tips of the engaging projections 14 and 14 ', a protruding edge 16 is provided for the outer half circumference.
Is formed, and the projecting edge 16 is engaged with the hole edge of the through holes 8 and 8 ', so that the engagement state is maintained. Therefore, when the ear cushion body 3 set on the cap body 1 is detached from the mounting base plate 5, the inner peripheral edge of the ear cushion body 3 is rolled up to project the edges of the engaging projections 14 and 14 '.
This can be performed by removing 16 from the edge of the through holes 8 and 8'and removing the positioning claw 13 from the claw receiving groove 7. When the outer peripheral edge of the ear cushion body 3 is rolled up, the hooking protrusion 1
Since the projecting edge 16 of 4 and 14 'is caught on the hole edge of the through holes 8 and 8', the engagement between the two cannot be released.

(Effects of the Invention) With the structure of the ear cushion mounting structure of the present invention configured as described above, when the ear cushion mounting structure is mounted on the side of the cap body, the mounting base plate and the base plate of the ear cushion engage with each other to fix the conventional fixing. A stable mounting condition equivalent to that of the formula is established, so it fits well even when wearing a helmet, and a stable wearing feeling with no glaring feeling can be obtained.

Further, since the mounting base plate and the base plate of the ear cushion body are engaged and disengaged by the resin-molded positioning claw and claw receiving groove, and the engaging projection and the through hole, each part is deformed and damaged even if frequently removed. It is possible to provide a product that can withstand long-term use without causing any trouble.
