DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an ear cup detachably mounted inside a helmet worn on a head when riding a motorcycle or a car.

[0002]

2. Description of the Related Art An ear cup mounted on a jet-type helmet is removably attached to left and right inner positions of a cap body in consideration of washing and size adjustment. The ear cup is composed of a pad body made of a cushion material and an exterior member such as a cloth or a mesh material covering the pad body, and is provided on the bottom side (surface facing the inner surface of the cap) covered by the exterior member. Is formed by bonding and fixing a resin plate provided with means for attaching to a cap body by hot melt. That is, the internal pad body cannot be taken out.

[0003]

Therefore, when washing an ear cup that is contaminated with sweat, dust, or the like, the entire ear cup is washed, which takes time to dry, and the pad body and the exterior member are integrated. Therefore, there is a problem that it is difficult to clean both of them cleanly. Also, this ear cup fills the gap between the cap body and the cheek to prevent the helmet from wobbling, but the size (thickness) of the ear cup for that purpose is selected from several types with different thicknesses Only
There is a problem that delicate size adjustment is difficult to perform.

Further, the conventional ear cup is of an integral wrap type in which the pad body is completely wrapped by the outer member. During the manufacture, the outer member is stretched and wrapped, so that the pad body is provided under the cushion material. When a cushioning material such as styrene foam is placed on the pad body to cover the cushioning material, the cushioning material is broken or chipped, so only the cushioning material is used for the pad body. However, when the protection function and the safety are pursued, it is better to include a cushioning material such as styrene foam. In the case of using only the cushioning material, the cushioning material is crushed by the tension of the exterior member, the shape of the ear cup is easily broken, and there is a problem in shape retention.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to separate a pad body and an exterior member so that they can be washed separately. Another object of the present invention is to provide an ear cup structure in which a size adjustment for adjusting a thickness can be easily performed, and a cushioning material for improving protection safety and shape retention can be inserted.

[0006]

The technical means taken by the present invention to achieve the above object is to provide a pad body having a substantially C-shaped planar shape, and a bag-shaped outer body for covering the pad body. the outer edge of the opening of the outer member or
Along one side edge of the inner edge, of the pad body

After the corresponding arrangement on the base plate , the ear frame is turned over and the opening of the exterior member is closed by the base plate and the ear frame .

[0007] The pad body covered by the exterior member may be made of a material obtained by laminating a cushion material such as urethane foam and styrofoam having shock absorption performance, or a cushion material such as urethane foam alone. Further, the base plate connected to either the outer edge or the inner edge of the opening of the exterior member is formed in substantially the same shape as the plane shape of the pad body, and the back surface thereof is provided with a means for attaching to the cap body. Are integrally formed.

According to the above means, the opening is formed in a bag shape.

[0017]

According to the first and second aspects of the present invention, the ear cup of the jet helmet according to the present invention can be separated into a pad body and an outer member constituting the ear cup. Cleaning (washing) can be performed separately, so that selection can be made even more cleanly, and since drying can be performed separately, drying can be performed in a short time. Also, because the pad body can be taken out, if the ear cup does not fit well on the cheek etc., replace it with a cushion material with a different thickness or cut a plate-shaped cushion material into a predetermined size Can be adjusted to fit tightly.
Of course, when the exterior member is very dirty or torn, only the exterior member can be replaced with a new exterior member. Further, since the wrapping by the exterior member is engaged by folding back the opening edge of the bag body, the force acting on the pad body during the wrapping operation is not strong. Therefore, even if a cushioning material such as styrene foam is used as the pad body. It is possible to provide an ear cup with a built-in cushioning material, which is excellent in protection and safety without fear of the cushioning material being broken. In addition, since the cushioning material can be used for the pad body as described above, the shape of the ear cup can be finely finished, and an ear cup excellent in shape retention can be provided. According to the configuration of the third aspect, the ear cup can be detachably attached to the helmet.
