Description

[Detailed explanation of the invention] A. Purpose of the invention (1) Industrial application field The present invention is a method of attaching multiple skin pieces to each other to cover the seat skin of motorcycles, scooters, and other two-wheeled vehicles, especially the seat cushion. Concerning things made by joining.

(2) Prior Art As shown in FIG. 5, the conventional seat skin is made by directly sewing adjacent skin pieces 5 and 6 to each other with threads 20, and then attaching a common patch to the back surfaces of these skin pieces 5 and 6. The cloth 19 is polymerized, and this cloth 19 and each skin piece 5, 6 are
and are sewn together with threads 21, 21.

(3) Problems that the invention aims to solve In the above conventional structure, there is no elasticity between the skin pieces, so when a tensile force is applied to the seat skin due to the weight of the occupant, concentrated stress is generated at the seams of each skin piece. This also has the disadvantage that the cushioning properties of the seat cushion are impaired to some extent.

This invention was made in view of these points,
It is an object of the present invention to provide a seat skin which prevents or alleviates the occurrence of concentrated stress at the joints between the skin pieces and allows the seat cushion to fully exhibit its cushioning properties.

B. Structure of the invention (1) Means for solving the problem In order to achieve the above object, the seat skin of the present invention is characterized in that adjacent skin pieces are joined via elastic strips. do.

(2) Effect According to the above configuration, the elastic bands provide elasticity between the skin pieces, and even if a tensile force is applied to the seat skin, stress concentration at the joints of the skin pieces is prevented or eased.

In addition, the seat skin can be expanded and contracted as a whole, and the cushioning properties of the seat cushion can be fully exhibited.

(3) Examples Examples of the present invention will be described below with reference to the drawings.

First, in FIG. 1 showing the first embodiment,
A tandem seat 1 for a motorcycle includes a bottom plate 2 made of a steel plate or synthetic resin, a seat cushion 3 made of urethane foam placed on the bottom plate 2, and a seat cushion 3 made of urethane foam.
Seat skin 4 that covers this and is bonded to the bottom plate 2
It consists of The seat skin 4 mainly includes a plurality of upper skin pieces 5a, 5b that cover the upper surface of the seat cushion 3, and a plurality of side skin pieces 6a, 6b that cover the side surfaces of the seat cushion 3. All of these skin pieces are made of vinyl leather.

Since the joint structures of the skin pieces 5a, 5b, 6a, and 6b are the same, a typical joint structure between the top skin piece 5a and the side skin piece 6a will be described with reference to FIG. do.

A common elastic strip 9 is superimposed on the inwardly folded portions 7 and 8 of the opposite ends of both skin pieces 5a and 5b, and this elastic strip 9 and each folded portion 7 and 8 are connected by threads 10 and 11. Further, the elastic band piece 9 and each skin piece 5a, 6a are sewn together with threads 12, 13, with the folded parts 7, 8 in between. In this way, the skin pieces 5a, 6a are joined via the elastic band 9.

The elastic strip 9 is cut from a fiber-filled rubber plate that is highly elastic and has high tensile strength.

Next, the operation of this embodiment will be explained. Since the elastic band 9 has elasticity, when the seat skin 4 receives a tensile force due to the weight of the occupant, the elastic band 9 stretches appropriately, and each skin piece 5a, It is possible to prevent or alleviate concentrated stress from occurring at the joints between 5b, 6a, and 6b.

In addition, due to the elasticity of the elastic strip 9, the seat skin 4
The seat cushion 3 can be expanded and contracted as a whole, and the cushioning properties of the seat cushion 3 can be fully exhibited.

FIG. 3 shows a second embodiment of the present invention. In this embodiment, a rubber decorative strip 14 is interposed between each skin piece 5a, 6a and a common elastic strip 9, and a protrusion is formed by bending the center part of this decorative strip 14. The structure is substantially the same as that of the previous embodiment except that 15 is interposed between the opposing ends of the skin pieces 5a and 6a, and in FIG. .

According to this embodiment, the protrusion 1 of the decorative strip 14
5 expands and contracts in accordance with the expansion and contraction of the elastic strip 9 and always fills the gap between the skin pieces 5a and 6a, so that the appearance of the seat skin 4 can be improved.

FIG. 4 shows a third embodiment of the present invention. In this embodiment, the elastic band 9 is made of rubber with a base cloth, and a bead 1 is integrally provided on the upper surface of the central part.
6 is the same as the first embodiment except that the skin pieces 6 are interposed between the opposing ends of the skin pieces 5a, 6a, and in FIG.
Parts corresponding to those in the first embodiment are given the same reference numerals.

According to this embodiment, the elastic strip 9 can be given a decorative function.

In each of the above embodiments, the elastic strip 9 can be made of polyvinyl chloride, and in such a case, the elastic strip 9 and the skin pieces 5a, 6a can be welded together.

C Effect of the invention As described above, according to the invention, the seat skin is
Adjacent skin pieces are joined via elastic strips, so the elastic bands give elasticity between the skin pieces, preventing stress concentration at the joints of each skin piece even when tensile force is applied. can be prevented or alleviated, and the durability of the seat skin can be improved.

In addition, the seat skin can be expanded and contracted as a whole, and the cushioning properties of the seat cushion can be fully demonstrated, contributing to improving the ride comfort of the vehicle.
