Description

  The present invention relates to fixing a sewn portion in a seat cover structure.

The seat cover that covers the seat back and the seat cushion is provided with a step at the sewn portion of the seat side portion to improve the appearance of the seat. For example, Patent Document 1 discloses a seat cover 50 that covers a pad 61 of a seat back 60 as shown in FIG. The seat cover 50 is mainly composed of a skin layer 53, a cover pad 54, and skin materials 51 and 52 including a back base cloth 55. The skin materials 51 and 52 are stitched by polymerizing the skin layer 53 sides at the terminal, and by folding back the stitched portion of the skin material 52 to the base point, the seam allowance 56 which is the terminal portion of the skin material between the skin materials 51 and 52, A seat cover 50 is formed by forming a stepped portion A composed of 57.
JP-A-8-266756

  The step of forming the stepped portion by folding back one of the skin materials from the stitching line is performed in the process of covering the pad with the seat cover at the time of seat assembly. For details, sew each skin material, reverse the seat cover with the back side upside down to make the skin layer face up, and then press the skin material against the pad when covering the pad with the seat cover. Is in contact with the back surface of the corresponding skin material to form a stepped portion. However, since the seam allowance is not fixed to one of the skin materials, the contact with the back surface of the skin material is not constant depending on how the seat cover is covered, and the state of the appearance appears on the surface of the skin material. There was a problem that damaged. In order to cope with such a problem, Patent Document 1 takes a countermeasure by scooping one of the skin material and one of the skin material after turning one of the skin materials around the sewing line as a base point. It was necessary to keep the eye out. Special jigs or skills were required and the workability was poor.

  The present invention is for achieving the above object, and the invention according to claim 1 is that the terminals are aligned and brought into a polymerized state so that the surface sides of the two skin materials face each other, and then the terminal portions are stitched, In the three-dimensional seat cover structure in which a step portion is formed by folding one of the skin materials, the skin is attached by attaching a locking member to the back surface of one end portion of the skin material or a position corresponding to the back surface of the terminal portion. It is characterized by being locked to a corresponding position on one back surface of the material or the back surface of the terminal portion.

  As a result, when the end portion of the skin material is folded back, the contact state can be made constant with respect to the corresponding position on the back surface of the skin material corresponding to the seam allowance that is the end portion of the skin material, so that it does not meander at the stepped portion. Since the seam allowance appears in a stable state on the surface of the skin material, the appearance quality is not impaired.

  According to a second aspect of the present invention, in the seat cover structure according to the first aspect, the locking member is attached to a cloth material, and the cloth material is simultaneously sewn together when the skin materials are stitched together, It is set so that the said locking member may be located in the terminal part back surface.

  As a result, the locking member can be attached simultaneously when the skin materials are stitched together, and the workability is good.

  FIG. 1 is an overall perspective view of a sheet main body according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG.

  The seat body 10 includes a seat cushion 12 and a seat back 11 and is connected by a reclining device 20. The seat cushion 12 includes a frame, a pad material 14 and a cover 13 (not shown).

  The seat cushion cover 13 is formed in a three-dimensional shape that matches the outer shape of the seat cushion 12 by stitching together a plurality of skin materials made of a top plate skin material 13a, a top plate side skin material 13b, and a stile skin material 13c formed in a predetermined shape. ing. A locking member (not shown) is attached to the lower end of the scab skin 13c for fixing to the frame.

  Next, the sewing of the top plate side skin material 13b and the hook skin material 13c, which is a feature of the present invention, will be described in detail. Each of the skin materials 13b and 13c is a fabric layer on the surface side of the seat or a skin layer 13b1 or 13c1 made of genuine leather, a cushion layer 13b2 or 13c2 made of a thin urethane material, a backing base fabric 13b3 or 13c3 made of a knitted fabric or a nonwoven fabric. Is formed by laminating a material formed by laminating or the like into three layers by a cutting machine. Each of the skin materials 13b and 13c is made to polymerize with the skin layers 13b1 and 13c1 facing each other and the end portions thereof aligned. At that time, the back base fabrics 13b3 and 13c3, which are the back surfaces of the skin materials 13b and 13c, respectively appear on the front side.

  And from the cotton cloth, the nonwoven fabric, etc. so as to wrap the end surfaces of the seam allowances 13bA, 13cA, which are the end portions of the skin materials 13b, 13c, on the side of the back base fabric 13b3, 13c3, which is the front side of the superposed both skin materials 13b, 13c A cloth material 15 is attached. The cloth member 15 is provided with a locking member 16 made of a male member of a hook and loop fastener at a position corresponding to the back base cloth 13b3 of the skin member 13b to be folded back later. Then, both sides of the top plate side skin material 13b, the hook skin material 13c, and the cloth material 15 are stitched with a predetermined thread by a sewing machine (not shown). Then, a suture line 17 is formed.

  Next, with this stitching line 17 as a base point, the peripheral edge portion of the top plate side skin material 13b is folded back so that the back base fabric 13b3 side is inward to be in a superposed state. Then, the locking member 16 attached to the cloth material 15 that wraps the seam allowances 13bA and 13cA, which are the tip portions from the suture line 17 of the top plate side skin material 13b and the hook skin material 13c, is the back of the top plate side skin material 13b. Locked to the base fabric 13b3.

  Then, the cover 13 is completed by inverting the top plate side skin material 13b so that the skin layer 13b1 and the skin layer 13c1 of the hook skin material 13c are located on the outer surface. At this time, the top plate side skin material 13b is folded back from the stitch line 17 of the top plate side skin material 13b and the hook skin material 13c, and the thickness of the folded top plate side skin material 13b is equal to the step 18 of the cover 13. Formed.

  After the top plate side skin material 13b and the hook skin material 13c are stitched in this way, the locking member 16 is locked to the back surface of the top plate side skin material 13b by folding the top plate side skin material 13b with the suture line 17 as a base point. As a result, the seam allowances 13bA and 13cA can be stably maintained with respect to the stepped portion 18. That is, the seam allowances 13bA and 13cA of the top plate side skin material 13c and the hook skin material 13b are held in contact in one direction, and the seat appearance design There is no degradation of the texture.

The present invention is not limited to the above-described embodiment, and may be the following form.
(1) In the above embodiment, the locking member is attached to the cloth material. However, the locking member may be directly attached to the sewing surface of the top plate side skin material.
(2) Moreover, you may attach a latching member to the part by which the seam allowance is located in the back surface of the side by which the top-plate side skin material was turned back.
