DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the lining structure of a helmet in which a lining material is attached to the inner surface of the helmet body.

(Prior Art) Helmets for automobiles, motorcycles, etc. have a shock absorbing liner made of a foamed material attached to the inner surface of the helmet body, and a lining material attached to the inner surface. The lining is fixedly attached and dimensioned by the inner surface of the lining. On the other hand, the size and shape of the head on which the helmet is worn differs from person to person, and for this reason, it is not easy for many people to obtain a helmet that perfectly fits their head.

(Object of the Invention) The present invention has been made to eliminate such conventional drawbacks, and in addition to making the lining material removably attachable, the size adjustment member is used to adjust the shape and size of the head. It can be adjusted according to the size.

(Structure of the Invention) The present invention provides a helmet in which a shock absorbing liner is attached to the inner surface of a helmet body, and a lining material is attached to the inner surface of the helmet, and the lining material is detachably attached. A dimension adjustment member is interposed between the ms absorption liner and the ms absorption liner.

In the above configuration, the size adjustment member can be placed at any position by removing the inner lining material, and thereby the size adjustment member can be configured to perfectly fit the shape and size of the human head. .

<Example> In Figs. 1 to 4, a helmet body 1 made of FRP is shown.
A shock-absorbing liner 2 made of a plastic foam material is attached to the inner surface of the shock absorbing liner 2, and a center section 3 and side sections 4 on both sides constituting the inner lining are arranged inside the shock absorbing liner 2. The shock-absorbing liner 2 is fixedly attached to the helmet body 1 with an adhesive or the like, and a center section 3 and side sections 4 are detachably attached to the inner surface of the shock-absorbing liner 2, respectively, as will be described later. Further, a chin pad 5 is removably attached to a portion facing the jaw, and a neck pad 6 is detachably attached to a portion facing the rear neck.

Edge members 8 made of rubber or the like are attached to the edges of the helmet body 1, that is, the edges of the lower opening and the front frontage.

The center section 3 is made up of a core material made of highly elastic cushioning material, such as soft polyurethane foam, covered with cloth, and forms part of a spherical surface along the center of the inner surface of the helmet as a whole. A locking piece 30 is provided at the front end of the locking piece 30, and as shown in FIG. 6, a large number of elastic bulges 31 are formed on the locking piece 30.

Instead of this bulging portion 31, a plate material may be formed into a corrugated shape.

In addition, a gap 21 is formed at the end of the helmet body 1 and the shock absorbing liner 2, and the bulge 31 is formed in this gap 21.
By inserting the locking piece 30 formed with , the bulging part 31 is compressed and clamped, thereby making it removably fixed.

Further, a locking part 32 made of Velcro or the like is provided at the base of the locking piece 30, and a locking part 22 made of Velcro or the like is also formed on the inner surface of the end of the fJs absorbent liner 2. 30 is inserted into the gap 21, the locking part 3
2 and 22 are pressed against each other and coupled.

A locking portion 34 similar to the above is also formed at the rear end of the center section 3, as shown in FIG.

The main part of the side section 4 is formed by covering a core material made of a cushioning material with high elasticity with cloth, and the main part of the side section 4 is formed as a part of a spherical surface along the inner surface of the helmet. Same as section 3. A locking piece 40 having a large number of bulges 41 in the same manner as described above is formed at the lower part of this main part, and a shock absorbing liner 45 is provided between this locking piece 40 and the main part as shown in FIG. is mediated. Further, a thin locking piece 42 is formed at the lower front peripheral edge, and a hole 44 through which the chin strap 7 is passed is formed at the center. The chin strap 7 is attached to the helmet body 1 by an attachment 17.

As shown in FIG. 8, the chin pad 5 is made up of a highly elastic core material covered with cloth, and has thin locking pieces 5 on the upper and lower edges.
0 is formed, and by inserting this locking piece 50 between the helmet body 1 and the edge member 8, the chin pad 5 is removably fixed to the helmet. As shown in FIG. 5, the night section 4 is continuous on both sides of the chin pad 5, and the thin end portion of the side section 4 is inserted between the chin pad 5 and the helmet body 1.

As shown in FIGS. 1, 2, and 7, the neck pad 6 has a crescent-shaped main part made of a cushioning core material covered with cloth, and one edge of the crescent-shaped main part has a similar structure as described above. Swelling part 6
A locking piece 60 having a number 1 formed thereon is provided. A gap 23 is formed between the rear part of the helmet body 1 and the end of the shock absorbing liner 2, and the locking piece 60 is inserted into the gap 23 to be removably fixed. Further, the neck pad 6 is provided with a locking portion 62 made of Velcro or the like, while a locking portion 24 made of Velcro or the like is also formed on the inner surface of the end of the shock absorbing liner 2, and the locking piece 6o is attached to the gap 22. When inserted into the locking part 62
and 24 are pressed together and coupled. In this state, the locking portion 34 at the rear end of the center section 3 is pressed against and coupled to the inner surface of the locking portion 62.

It should be noted that various structures other than those described above can be adopted as the structure for attaching and detaching the center section 3 and the side sections 4.

A cushioning material of an appropriate thickness is provided between the center section 3 and side sections 4 and the shock absorbing liner 2, as shown in FIGS. (Dimension adjustment member) 9 is interposed.

This cushioning material 9 is made up of three members corresponding to the center section 3 and side sections 4, respectively, and each member is formed in a shape corresponding to the shape of the center section 3 and the side section 4 except for the upper part. Note that the shape and thickness are not limited to those illustrated above, and may be set arbitrarily.

In the above configuration, as shown in FIGS. 2 and 6, the center section 3 connects the locking piece 30 at the end to the gap 2.
The shock absorbing liner 2 is fixed to the helmet by being inserted into the shock absorbing liner 2 and by aligning the main part, which is a part of the spherical surface, along the inner surface of the shock absorbing liner 2. At this time, the locking part 32 is brought into pressure contact with the locking part 22, and as shown in FIG.
4 through the locking part 62,
It can be fixed more firmly. To remove the center section 3, it is only necessary to pull out these locking pieces and locking portions, and the attachment and detachment can be performed extremely easily.

The side section 4, as shown in FIGS. 2 to 4,
The locking piece 42 is inserted between the end of the helmet body 1 and the edge member 8, and the locking piece 40 is inserted into the shock absorbing liner 2.
It is fixed by being inserted between the end of the helmet (the position indicated by the broken line in FIG. 2) and the helmet body 1. It can be removed by pulling the locking piece. Similarly, the chin pad 5 is attached and detached by inserting and pulling out the locking piece 50 between the helmet body 1 and the edge member 8, as shown in FIG. 8, and the neck pad 6 is attached and detached as shown in FIG. Then, the locking piece 60 is inserted into the gap 23 and handled, thereby attaching and detaching it.

After the cushioning material 9 is placed in a predetermined position with the center section 3 and side sections 4 removed, the center section 3 and side sections 4 are restored to press and fix the cushioning material 9. By arranging this cushion material 9, the lining material protrudes inward by an amount corresponding to its thickness and shape, reducing the volume into which the head is inserted, so the thickness and shape of this cushion material 9 are set appropriately. This allows for a perfect fit depending on the shape and size of the wearer's head.

In the above embodiments, only a so-called full-face type was described, but the present invention is similarly applicable to a jet type.

(Effects of the Invention) As explained above, the present invention is such that the lining material of a helmet is detachably attached, and a dimension adjustment member is interposed between the lining material and the shock absorbing liner. By removing the lining material, the size adjustment member can be placed in any desired position, and thus can be configured to perfectly fit the shape and size of a person's head.
