Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to an assembly structure of a vehicle seat such as an automobile seat, and more particularly, the present invention has a protruding side cushion portion on the left and right sides of a main cushion portion (bucket-shaped side cushion portion). This invention relates to an assembly structure for a skin member that forms the surface of a vehicle seat.

(Prior Art) Conventional vehicle seats, especially bucket-shaped seat bags for automobiles, have a main cushion made of foam;
It has a structure in which a cushion member consisting of raised side cushions integrally molded on the left and right sides is placed against a seat frame stretched with spring material, and these are covered with a skin member sewn into a bag shape. The skin member is fixed to the surface of the bucket-shaped cushion member with clips along the boundary between the main cushion and the side cushion, or the skin member is attached along the boundary line between the main cushion and the side cushion. A string-like hanging member was sewn to the back side, and this hanging member was hung in the longitudinal direction (vertical direction).

Therefore, in the former case, it is difficult to fix the skin member in a straight line along the boundary line between the main cushion and the side cushion, and the skin member may meander, and in the latter case, the skin member is attached to the bucket-shaped cushion member. Since the hanging member must be manually pulled in its longitudinal direction (vertical direction) so as to come into close contact with the surface, there is a drawback that the workability of assembling the skin member is extremely poor.

Therefore, there is a method disclosed in Japanese Unexamined Utility Model Publication No. 166800/1983 as a method for eliminating the above-mentioned defects. In this method, the skin member is separated in the longitudinal direction, and an engaging tool is provided at the end of the separated part to connect the separated part.
The structure is such that after the cushion member is covered with this engagement tool, the separation part is joined together. Therefore, according to this structure, it is easy to assemble the skin member, but since the skin member is not fixed to the cushion member, the skin member cannot be in close contact with the surface of the bucket-shaped cushion member, and the skin member cannot be attached to the specified surface. A problem arises in that it cannot be assembled to the external shape.

(Object of the Invention) An object of the present invention is to enable a skin member to adhere to the surface of a bucket-shaped cushion member simply, easily, and beautifully.

(Structure) The present invention has a cushion member formed separately into a main cushion part and a side cushion part, and an insertion piece extending along the side cushion side at the lower part of the main cushion part. This insertion piece was inserted into the insertion groove provided on the side of the main cushion part of the side cushion part, or between the side cushion and the support member on which this side cushion was placed, to fix the main cushion part. The main cushion part and the side cushion part are composed of a cushion member made of foam and a skin covering the surface of the cushion member, and the insertion piece of the main cushion part is inserted into the end of the skin. It is a band-shaped synthetic resin plate that is fixed by sewing or the like and has a predetermined rigidity.

In this way, the insertion piece of the main cushion part formed separately from the side cushion part is inserted into the side cushion part, or by being held between the side cushion part and the support member. Because it is fixed, assembly work efficiency is improved compared to conventional products.
Further, since the skin member can be attached to the main cushion portion and the side cushion portion respectively before the main cushion portion is assembled, there is no need to form the skin member into a bag shape as in conventional products. Therefore, the skin member can be accurately and easily assembled to each cushion member.
