Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle seat, and particularly to a vacuum-formed sheet whose skin is processed by a vacuum-forming method.

Generally, a vehicle seat, for example, a seat for a motorcycle, has a bottom plate 1, as shown in a longitudinal cross-sectional view in FIG.
Then, the back surface 2b is in close contact with the surface 1a of the bottom plate 1,
It also consists of a base material 2 whose surface 2a forms a sheet shape, and a skin 3 that is in close contact with the surface 2a of the base material 2, and the peripheral edge of the skin 3 is close to the back surface 1b of the bottom plate 1.
The end portion 3a is folded back to the side, and the end portion 3a is fixed to the periphery of the back surface 1b of the bottom plate 1 by a fastening pin 5 via a tape-shaped fastening member 4. If the skin 3 has no seams, it is processed by a so-called vacuum forming method in which the skin 3 is softened by heating and molded in close contact with a mold using a vacuum. A base fabric 7 made of knitted fabric or nylon fabric is adhered to the entire back surface of the fabric 6.

However, although knitted base fabrics are inexpensive, they have the disadvantage of poor conformability during vacuum forming and are difficult to use for sheets with complex shapes, while nylon base fabrics have good elasticity and conformability. Although they have excellent properties, they have the drawback of being made of expensive materials and increasing costs.Furthermore, in both cases, the base fabric makes the skin a little hard, which hinders good sitting comfort. On the other hand, not using any base fabric is not suitable for implementation because the strength of the attachment of the seat skin to the bottom plate will be insufficient.

The present invention has been made in view of the above-mentioned drawbacks.The present invention is a vehicle seat consisting of a bottom plate, a base material, and a skin, in which the skin is made by vacuum forming, and the base material is formed only on the back surface near the part where the skin is attached to the bottom plate. It is a vacuum-formed sheet characterized by the fact that it is pasted with It is an object of the present invention to provide a vacuum-formed sheet that can be easily seated and has good seating properties.

The present invention will be described in detail below based on embodiments shown in the drawings.

FIGS. 2 and 3 show an embodiment in which the present invention is applied to a motorcycle seat, and the seat is composed of a bottom plate 1, a base material 2, and a skin 3, as in the conventional case.
The outer skin 3 is made of polyvinyl chloride material 6, unlike the conventional one.
The base fabric 7 is adhered not to the entire back surface of the sheet, but only to its periphery, that is, from slightly closer to the sheet surface than the folded portion 6a to the end portion 3a.

In order to produce the skin 3 having the base fabric 7 only on the periphery as described above, the base fabric 7 is placed at a predetermined position on the mold side during the conventional vacuum forming without using a separate process. Outer fabric made of polyvinyl chloride material 6
If vacuum forming is carried out by placing a chisel over it, the base fabric 7 will be adhered to a predetermined position of the outer fabric 6 by the heat generated at that time, forming the outer skin 3 as described above.

Further, FIG. 4 shows another embodiment, which differs from the above embodiment in the means for fixing the outer skin 3 to the bottom plate 1, in which the fixing member 4 is not used and the end portion 3a of the outer skin 3 is used.
is directly fixed to the bottom plate 1 using the fixing pin 5, which further reduces costs and simplifies the work of fixing the skin to the bottom plate.

It goes without saying that the material of the base fabric does not matter in the present invention.

Since the present invention has the above-mentioned configuration, it is possible to reduce the cost by using a small amount of base fabric for the skin, and furthermore, the strength of the attachment part of the skin to the bottom plate is not impaired, and the seating area skin is Since it does not have a base fabric, the softness of the sheet is improved, the sheet can be made to have good sitting comfort, and the production process is also simple, among other effects.
