Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a helmet, such as a riding helmet or a protective helmet, that is worn on the head to protect the head from impact.

(Prior Art) Riding helmets, protective helmets, etc. generally consist of a hard shell and a cushioning material placed inside the shell.

Conventionally, in this type of helmet, the cushioning materials are foamed plastic or the like for the first layer closest to the hard shell, and brushed tricot fabric or the like for the inner second layer that contacts the head. The most common structure was a pad made of laminate.

Japanese Unexamined Patent Publication No. 60-28505, 60-28506
The publication describes a helmet ventilation system in which a running air intake is provided on the front of the helmet, and a plurality of ventilation grooves are cut into the cushion pad to communicate with it, or a through hole is provided on the inner surface of the cushion pad and communicated with the ventilation grooves. It is shown that it is provided on the cushion pad. It is also stated that the cushioning liner of this helmet is made of styrofoam, and the cushion pad is made of urethane foam.

(Problems to be Solved by the Invention) Both foamed plastic and foamed polyurethane have no air permeability. Even if brushed tricot fabric or the like is pasted together, breathability cannot be ensured. Therefore, the sweat generated by the head is not released to the outside of the helmet, and the inside of the helmet becomes stuffy over time when the helmet is worn.

The present invention aims to solve such problems.

(Means for Solving the Problems) The present invention provides a helmet made of hard plastic that is composed of a multilayer fabric made by bonding a plurality of fiber sheets with a connecting material as a cushioning material alone or by layering multilayer fabrics. In a helmet characterized by: and a helmet made of hard plastic, a foamed plastic layer is used as a cushioning material as the first layer closest to the shell, and the second layer is the innermost layer that comes into contact with the head when worn. This helmet is characterized in that it is constructed by laminating a multilayer fabric, which is made by bonding a plurality of fiber sheets with a connecting material, either singly or by laminating a plurality of fabrics as a cushioning material.

Next, the present invention will be explained with reference to the drawings. Figure 1 shows a full-face helmet among riding helmets,
A window hole 2 is opened in front of the cap body 1, and a transparent shield 3 is detachably attached so as to cover the entire window hole 2.
The shield 3 is freely pivoted around the pivot 6. The cap body 1 consists of a hard shell 4 made of hard plastic with high impact resistance, and a cushioning material 5 disposed inside the hard shell. The present invention is an improvement on this cushioning material 5.

The fiber sheet referred to in the present invention includes, for example, knitted fabrics, woven fabrics,
There are nonwoven fabrics, etc. Examples of the connecting material include threads, tape-like materials, sheet-like materials, and the like.

For the fiber sheet and the connecting material constituting the cushioning material 5 of the present invention, materials such as natural fibers, synthetic fibers, inorganic fibers, and metal fibers can be used, for example. - As an example, a multilayer fabric made by bonding two fibrous sheets made of hydrophobic fibers with a linking material of hydrophilic fibers is more preferable as a means to solve the problem.

FIG. 2K shows an example of a multilayer fabric used as a cushioning material in the present invention. In the figure, 5 a / and 5 i' are fiber sheets placed in opposing positions, and 7 is a connecting material.

5a' and 5a# are connected to each other by 7.

FIG. 3 shows a pair of opposing loop-shaped stitch rows 5a'5a''
This is a multi-layered fabric composed of a connecting thread 7 that interconnects the stitch rows.

FIG. 4 shows an insertion yarn 11 inserted between the connecting yarns diagonally to the connecting yarn 7 and parallel to the surface of the loop-shaped stitch row 5a'5a'' in the multilayer fabric base. An example of a multilayer fabric including:

FIG. S shows that the cushioning material according to the present invention is inserted between a pair of opposing loop-shaped stitch rows 5a'5a'', a connecting yarn 7 that interconnects the stitch rows as a connecting material, and the connecting yarns. A strip member 13 consisting of three inserted threads 11, 11', and 11'' constitutes a honeycomb core by having a zone X partially joined to the adjacent strip member 13' by the inserted threads. The figure shows a multilayer fabric made of

FIG. 6 is an example of a multilayer fabric obtained by a two-stage loom. Warp 5a-15a-2 and weft 12, L'
This figure shows a multi-layered fabric in which two pieces of fabric woven together are connected by warp threads 5a-35a-4 supplied from a beam different from the warp threads of the ground weave.

FIG. 7 shows a sheet-like material made of two fibrous materials formed on a band-like member 13 formed by forming a sheet-like material made of a fibrous material into a corrugated sheet with irregularities using a corrugated roll and bonding these sheets in parallel. 5a'5a'' is shown as a honeycomb structure as a sandwich panel with bonded outer panels.

FIG. 8 shows a helmet made of hard plastic in which a foamed plastic layer 5s is used as a cushioning material as the first layer closest to the shell 4, and the second layer is the innermost layer that comes into contact with the head when worn. 5 is a cross-sectional view of a helmet constructed by laminating a layer of multilayer fabric 5b shown in FIG. 4 as a cushioning material. FIG.

FIG. 9 is a sectional view of a helmet according to an embodiment of the present invention. Multilayer fabrics 5a, 5b, 5c are provided inside the shell 4.

5d is a sectional view of a helmet provided with a cushioning material 5 which is a laminated structure consisting of four layers.

FIG. 10 shows only the laminated structure consisting of the four layers. A pair of opposing loop-shaped stitch rows 5a'
5a'' and connecting threads 7 that interconnect the stitch rows, and multilayer fabrics 5b, 5c, and 5d having similar structures prevent displacement in the vertical, horizontal, and directional directions. For Ic, 5a" and 5b'5b" and 5c'
A structure in which 5c" and 5d" are laminated with each other bonded is shown.

(Effects of the invention) As mentioned above, the voids created by the connecting materials of these multilayered fabrics are similar to a structure in which countless thin pillars support the space between the ceiling and the floor, and have good ventilation, allowing the wind to blow between the connecting materials. but,
It effectively releases water vapor from the ceiling or floor to the outside of the helmet.

Using thread as the connecting material further improves breathability.

Further, if the connecting material is formed into a honeycomb shape, the effect as a buffer material is further improved. When seven 3s layers of multilayer fabric are laminated, the cushioning effect is further improved.

Moreover, as shown in FIG. 8, immediately inside the hard shell 4,
By arranging a layer of foamed plastic 5s and further arranging the multilayer fabric layer 5b inside it, it is possible to easily reduce the impact acceleration without increasing the thickness, compared to the case where only the multilayer fabric is used. At the same time, it is possible to prevent heat from entering from the outside, and at the same time, it is possible to quickly release humidity caused by heat generation and perspiration from the inside to the outside.
