[Embodiment of the invention]

 Hereinafter, a preferred embodiment of a helmet ear cover according to the present invention will be described with reference to FIGS. FIG. 1 is a partial cutaway view showing an embodiment of a helmet ear cover according to the present invention, showing a state of attachment to a helmet. 2 is a perspective view showing the helmet earpiece of FIG. 1, FIG. 3 is an enlarged sectional view taken along the arrow AA of FIG. 2, and FIG. 4 is an exploded perspective view of the helmet earpiece of FIG.

The helmet earpiece 1 of this embodiment comprises a cloth-made earpiece body 2, a flexible insertion plate 3 sewn on the upper part of the earpiece body 2, and a faceplate of the earpiece body 2. And a chin string passing portion 4 provided. The whole is flat and almost fan-shaped, and the left and right are almost line-symmetric.

The earpiece body 2 is made of a fabric having a certain degree of air permeability, stretchability and cushioning properties, such as flannel or a fabric whose surface is brushed, and has a fan shape as a whole with a mountain-shaped upper side. The two cloth elements 20 and 21 cut as described above are overlapped and sewn.

On one surface of the ear pad body 2, when sewing the above-mentioned cloth elements 20, 21, a band-shaped chin strap presser 41 made of the same material as the ear pad main body 2 and having upper and lower edges prevented from fraying by sewn-up sewing. Are simultaneously sewn to form the chin string passing portion 4.

The insertion plate 3 is made of an elastic polypropylene sheet having a thickness (in this embodiment, thickness = 0.5 mm) that can be cut with scissors, a knife, or the like. It is cut so as to substantially correspond to the upper side shape of the backing body 2 and to have a divergent shape upward. The lower edge of the insertion plate 3 cut in this manner is sewn to the upper edge of the earpiece body 2.

The helmet earpiece 1 of this embodiment is sewn, for example, as follows in order to finish it efficiently and durably. As shown exploded in FIG. 4, the lower edge of the insert plate 3 is first superimposed on the upper edges of the fabric elements 20, 21 in such a manner as to be sandwiched between them. Are sewn up and down in two rows. In order to facilitate this stitching, all or a part of the overlapped portion between the cloth elements 20 and 21 and the insertion plate 3 may be previously bonded (temporarily fixed). Next, a chin strap retainer 41 whose upper and lower edges have been sewn in advance is superimposed on one surface of the cloth elements 20 and 21 so that both sides thereof coincide with each other, and a cloth including an overlapping portion with the chin strap retainer 41 is provided. The overlapping peripheral edges of the elements 20 and 21 and the lower peripheral edge are continuously covered with an edge cover (cloth) 22, and the portion covered with the edge cover 22 is stitched and finished. As shown in FIGS. 1 and 2, on both side edges near the lower side of the insertion plate 3, the overlap between the cloth elements 20 and 21 and the insertion plate 3 is also covered by the edge cover 22, and these overlaps are provided. It is also preferable to sew the parts together.

The helmet earpiece 1 of the above embodiment is used by being attached to a helmet 5 having no earpiece as shown in FIG. 1. The attachment procedure will be described below. The helmet 5 has a shock-absorbing liner and other cushioning materials 51 inside a bowl-shaped helmet main body 50, and an upper part formed in a bifurcated shape inside the both ears of the helmet main body 50. The upper end of the chin strap 52 is attached by rivets 53a and 53b. The chin strap 52 of the helmet 5 as described above is passed through the chin strap passing portion 4 of the ear pad 1 in an upward and downward direction, and the insertion plate 3 is attached to the helmet body 50 and the cushioning material 51 between the rivets 53a and 53b. The earpiece 1 is attached to the helmet 5 by inserting it into the gap 5a between the earpiece 1 and the helmet 5.

Since the insertion plate 3 has flexibility, when the insertion plate 3 is inserted into the gap 5a, the insertion plate 3 is inserted while being deformed corresponding to the curved shape of the side portion of the helmet main body 50, and the interval between the rivets 53a and 53b is changed. Even if it is smaller to some extent than the width in the left-right direction of No. 3, it enters between the rivets 53a and 53b while bending and deforming. When the interval between the rivets 53a and 53b is somewhat smaller than the width of the insertion plate 3 in the left-right direction, when inserting the insertion plate 3 into the gap 5a, firstly, one upper portion of the insertion plate 3 is connected to the upper portion. It is also possible to insert it while making contact with the corresponding rivet, and to insert another part of the insertion plate 3 sequentially into the gap 5a. When the interval between the rivets 53a and 53b is smaller than the width of the insertion plate 3 by a certain amount or more, the insertion plate 3 may be cut into an appropriate size and shape using scissors or the like.

Since the insertion plate 3 has flexibility as described above, the insertion plate 3 bends along the curved shape of the helmet main body 50 in the gap 5a at the time of insertion, and the inner wall of the helmet main body 50 after insertion. The mounting state is almost stabilized by the force for restoring the original shape to the cushioning material 51.

In a state where the insertion plate 3 is inserted into the gap 5a, it is preferable that both side edges of the insertion plate 3 are locked to the shaft portions of the rivets 53a and 53b for stabilizing the mounting state.

The earpiece 1 for a helmet of this embodiment is symmetrical in the left-right line, and the fabric elements 20 and 21 constituting both surfaces of the earpiece body 2 and the chin strap holder 41 are made of the same material. For this reason, the helmet 5 may be mounted upside down so that the surface provided with the chin strap holder 41 abuts against the ear.

According to the helmet earpiece 1 of this embodiment, since the insertion plate 3 is attached to the helmet 5 by being inserted into the gap 5a of the helmet 5, the attachment and removal thereof are easy, and the earpiece is easy. It can be used universally for helmets without parts. In addition, since no special attachment / detachment means is required, it can be manufactured at lower cost.

Secondly, since the chin string passing portion 4 for vertically passing the chin string 52 of the helmet 5 is provided on one surface of the ear pad body 2, the ear pad body 2 is integrated with the chin string 52. When the helmet 5 is worn and the chin strap 52 is tightened, the earpiece body 2 comes into close contact with the ear.

Third, since the insertion plate 3 has a shape whose upper side is substantially mountain-shaped and diverges upward, the shape of the upper side of the mountain is easy to insert by bearing the action of the insertion guide. The mounting state is stabilized by locking both side edges to the shaft portions of the rivets 53a and 53b.

Fourth, since the insertion plate 3 can be cut with scissors, a knife, or the like, by cutting the helmet 5 according to the structure and shape of the helmet 5, it can be used more widely for various helmets. be able to.

Fifth, since the lower edges of the insertion plates 3 are overlapped in such a manner as to be sandwiched between the upper edges of the cloth elements 20 and 21, and the overlapped portions are sewn up and down in two rows. Even if the insertion plate 3 and the earpiece main body 2 are made of different materials, the ears are not damaged by the lower edge of the insertion plate 3.

Sixth, since the entire body is formed to be symmetrical with respect to the left and right lines, it can be mounted without distinction between the left ear part and the right ear part. 2 and the chin strap holder 41 are made of the same material, so that they can be mounted without distinction between front and back.

Other Embodiments The insert plate 3 according to the present invention is not necessarily required to be made of the polypropylene as long as it has a certain degree of flexibility. For example, a plastic sheet such as polyethylene, polycarbonate, or PVC, It can be carried out on leather, synthetic leather or other materials.

In the present invention, the earpiece main body 2 does not need to be the same fabric of the same shape as in the above-described embodiment, and the chin strap holder 41 is also the same fabric. No need. That is, for example, the surface that comes into contact with the ear may be made of brushed fabric or fur, etc., which is excellent in cold protection, and the other surface may be made of leather, synthetic leather, rubber, or the like, having excellent strength. Either surface may be slightly larger. Further, the earpiece main body 2 may be made of a single piece of cloth, leather, synthetic leather, rubber, or other common material as long as the material has a certain degree of elasticity and strength.

When the gap between the helmet body and the cushioning material is extremely wide, such as a security helmet, for example, a simple attachment / detachment means such as a cloth fastener is provided on the insertion plate 3 and the inner surface of the helmet body. The mounting state can be made more stable by providing. In the above-described embodiment, the earpiece main body 2 and the insertion plate 3 are made of different materials. However, both may be integrally formed of the same material such as leather, synthetic leather, and rubber. In this case, a cloth, a brushed cloth, fur, or the like may be fixed to a portion to be touched by the ear during use.
