Description

  The present invention relates to a vehicle seat including a seat cover in which a plurality of sewing lines are arranged in a cross shape such as a cross or a T-shape.

  This type of seat cover is typically formed by stitching a plurality of skin pieces, and a sewing line is formed between adjacent skin pieces and appears on the surface. In the field of vehicle seats, a plurality of sewing lines may be formed in a cross shape from the viewpoint of improving the design of the seat cover. For example, a sewing line extending in one direction is formed between these skin pieces while forming a first portion that forms a part of the seat cover by sewing a pair of skin pieces together at the seam margins formed at these ends. Form. Similarly, a pair of other skin pieces are stitched together at the seam allowances formed at these end portions to form a second portion that forms the other part of the seat cover, and one other skin piece is placed between these other skin pieces. A sewing line extending in the direction is formed. And a 1st site | part and a 2nd site | part are stitched together, and another sewing line is formed in cross | intersection with respect to the sewing line extended in one direction between these each part. At this time, for example, the seam allowance portion of the first part is tilted to expose the sewing line, and other sewing lines are formed perpendicular to the respective sewing lines using the sewing line as a mark. Thus, each sewing line and the other sewing lines appear on the surface of the seat cover while crossing in a cross shape.

  Then, the seat cover is placed on a seat pad that elastically supports the occupant. At this time, with each seam allowance as a base point, the adjacent skin pieces are developed in a planar shape to cover the seat pad, so that the seam allowance of each skin piece protrudes toward the seat pad. In this type of configuration, it is desirable to make the protruding dimension of the seam allowance as small as possible in consideration of the seatability of the seat. For example, using the sewing machine described in Patent Document 1, the seam allowance is cut and shortened simultaneously with the stitching of each skin piece. By shortening the seam allowance protruding to the seat pad side in this way, it is possible to suppress the deterioration of seat seating as much as possible.
