Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a seat back for a vehicle seat such as an automobile, and more specifically, a seat back in which the back is covered with a skin member and which has bulges on the left and right sides of the front side. The present invention relates to a seat bag (of a so-called bucket type) having a shaped side cushion portion.

(Prior art) A conventional bucket-shaped seat back consists of a main cushion made of foam and raised side cushions integrally molded on the left and right sides of the cushion member, which is applied to a seat frame stretched with spring material. ,
These are covered with a skin member sewn into a bag shape, and the skin member is attached to the surface of the bucket-shaped cushion member with clips or the like along the boundary between the main part and side parts, or is attached to the main part. A string-like hanging member was sewn to the back side of the skin member along the boundary line between the skin member and the side pad, 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 a bucket-shaped cushion member. Since the hanging member must be manually pulled in the longitudinal direction (vertical direction) so that it comes into close contact with the surface of the skin member, there is a problem that the workability of assembling the skin member is extremely poor.

Therefore, there is a technique disclosed in Japanese Utility Model Application Laid-Open No. 59-166800 to eliminate the above-mentioned problems. In this method, the skin member is separated in the longitudinal direction, and an engaging part is provided at the end of the separated part to connect the separated part,
After covering the cushion body with this engagement tool,
This structure connects the separated parts 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. There is a defect that makes it impossible to assemble the external shape.

(Object of the Invention) An object of the present invention is to enable a skin member to be brought into close contact with a bucket-shaped cushion member simply, easily, and beautifully.

(Structure) In the present invention, the cushion part is formed separately into a main cushion part and a side cushion part, and on both opposing sides of the side cushion parts,
