DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern structure of a skin material in a seat cushion or a seat back of a vehicle seat or the like. More specifically, a sewing portion is provided at a pattern position of the skin material. The present invention relates to a pattern structure of a sheet skin material in which a front end side is inserted into a pattern groove formed in a pad material and a pattern portion of the skin material is locked in the pattern groove of the pad material.

[0002]

2. Description of the Related Art For example, in a vehicle seat mounted on an automobile or the like, a seat cushion and a seat back erected on the back side thereof are generally constituted by a seat frame, a pad material, and a skin material covering the periphery thereof. Have been.

In the above-described seat cushion and seat back, as is apparent from FIGS. 5 and 6, an appropriate position of the seating surface of the vehicle seat is provided with an accent from the design point of view. The pattern 3 is formed at an appropriate position on the surface of the skin material 1 for reasons such as improving the appearance of the vehicle seat.

In such a pattern 3 of the skin material 1, a joint stitch portion 5 as a sewing portion is formed at a terminal 1 a of the skin material 1, and a hook-and-loop fastener 7 is provided at a tip end side of the joint stitch portion 5.
And a groove 2a for pattern formed in the pad material 2.
A hook-and-loop fastener 8 is attached to the
Is inserted into the concave groove for pattern 2a, and the hook-and-loop fastener 7 on the distal end side of the joint sewing portion 5 is engaged with the hook-and-loop fastener 8 of the concave groove 2a for pattern.

[0005]

However, in the conventional pattern structure of the skin material described above, the seam 5 of the terminal 1a of the skin material 1 is inserted into the pattern groove of the pad material 2 at 2a. Since the hook-and-loop fastener 7 is only engaged with the hook-and-loop fastener 8, it is difficult to express the pattern 3 in the form of a deep groove formed of large recesses. In addition, the shape of the deep groove may be formed by using a pulling member or the like, but the number of parts such as the pulling member increases, the cost increases, and there is a fear that wrinkles are generated in the skin material and the appearance is deteriorated. This has the disadvantage that the sitting comfort and fit are poor.

The present invention has been made in view of such circumstances, and a pattern of a skin material of a seat cushion or a seat back is formed by a very simple structure and a high quality deep groove-shaped strip by a simple operation. It is possible to express, a pattern state can be obtained easily and quickly, there is no possibility that wrinkles will occur in the skin material, it is possible to improve sitting comfort and fit, and there is no risk of deteriorating the appearance. It is intended to obtain a pattern structure of a skin material for a sheet which is excellent in workability and economy.
