2. Description of the Related Art As a seat back of a seat for a vehicle or the like, a structure as shown in FIGS. 5 and 6 has been widely known. In this seat back 1, an elastic member 3 made of a spring, a wire and the like is stretched between a pair of left and right side frames (not shown) of a seat back frame 2 formed in an inverted U shape. A pad member 6 is attached to the front surfaces of the seat back frame 2 and the elastic member 3 via a plate-shaped support member member 5 made of non-woven fabric or the like.
Is covered with a skin material 7. A bag-shaped pulling member 8 is fixed to the back surface of the skin material 7 that covers the front side of the pad material 6, and the pulling member 8 is pulled backward from the hole 6a formed in the pad material 6 to cause the elastic member 3 to move. Was attached to a part of the clip 9 by a clip 9 or the like.

[0003]

In the above-mentioned conventional structure, since the elastic member 3 such as a wire and the pulling member 8 are directly fixed to the clip 9, the clip 9 moves back and forth and the like. It has a drawback that it produces an unpleasant interference sound with the elastic member 3. Therefore, although a sound deadening material made of a non-woven fabric or the like is previously attached to the elastic member 3 at the position where the clip 9 is fastened, it has a drawback that the work of mounting the sound deadening material is complicated and the cost is increased. It was

The support material 5 is a pad material 6
Protects the pad member 6 by preventing it from coming into contact with the elastic member 3 and the seat back frame 2, but conventionally, in order to clip the pulling member 8 to the elastic member 3, the support member member 5 is vertically moved. Since the clip 9 is formed separately and the hole 5a for fixing the clip 9 is formed,
There is a risk that the pad material 6 will contact the elastic member 3 near the stop, and the pad material 6 cannot be sufficiently protected.

The object of the present invention is to prevent the interference sound from being generated with the clip without attaching a sound deadening member to the elastic member, and also to use the supporter material in a desired size in the vicinity of the clip stop. The above provides a mounting structure for a skin material capable of sufficiently protecting the pad material.

[0006]

The present invention has been made in view of the above-mentioned problems, and a plate is provided on the front side of a seat back frame and an elastic member stretched between a pair of left and right side frames of the seat back frame. The pad material is attached via a support material having a rectangular shape, the surface of the pad material is covered with a skin material, and a pulling member is attached to the back surface of the skin material covering the front side of the pad material. It is characterized in that it is pulled backward from a hole formed in the portion and clipped to the elastic member side through the supporter material.

[0007]

According to the present invention, since the pulling member and the elastic member are clipped to each other via the supporter material, it is not necessary to cut out the supporter material by forming a hole in the vicinity of the clip, and the pad material can be sufficiently attached. Can be protected.
Moreover, since the supporter material is interposed between the elastic member and the pulling member, the movement of the clip can be restricted, and the occurrence of interference sound between the clip and the elastic member can be prevented without separately attaching a sound deadening material or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A skin material mounting structure according to the present invention will be described below in detail with reference to the drawings. 1 and 2 respectively show an outline of one embodiment of the present invention. A seat back 11 is a seat back frame 12 formed by bending a pipe frame or the like into a substantially inverted U shape, and the seat back 11. A support member 15, a pad member 16 and a skin member 17 mounted so as to cover an elastic member 13 made of a wire or the like stretched between the left and right side frames 12a of the frame 12 are provided.

The supporter material 15 is formed of a plate-shaped nonwoven fabric or the like, and the pad material 16 is used as the seat back frame 12.
Also, the pad member 16 is attached so as to cover the entire inside of the pad member 16 for protection from the elastic member 13. The supporter material 15 can be attached by integrally foaming with the pad material 16. A bag-shaped pulling member 21 made of cloth, a resin sheet, or the like is fixed to the back surface of the skin material 17 which constitutes the front side of the seat back 11, and the seating feeling is improved by pulling the skin material 17 substantially in the center rearward. Etc. In the pad material 16 near where the pulling member 21 is fixed, hole portions 16a are cut out in an arc shape in the vertical direction.
Is formed so that a clip 25 fastening operation described later can be easily performed. Reference numeral 27 in the drawing is a core material for maintaining the strength and shape of the pulling member 21. Further, the shape of the pulling member 21 and the hole 16a can be changed as appropriate.

The pulling member 21 is clipped to the elastic member 13 via the supporter material 15 while being pulled backward. A small hole 23 for positioning a clip 25 is formed in the supporter material 15, and the clip 25 attaches the pulling member 21 and the elastic member 13 through the small hole 23. The small hole 23 may be omitted, and may be a slit or the like. With such a configuration, it is possible to effectively prevent the clip 25 from moving back and forth, and there is no fear that the clip 25 and the elastic member 13 interfere with each other to cause a rattling noise. Further, since the supporter material 15 can be used in a desired size without being divided and formed, the supporter material 15 is also interposed between the elastic member 13 and the pulling member 21, and near the clip 25 stop. Also, the pad material 16 can be sufficiently protected by the support material 15.

FIGS. 3 and 4 show modified examples of the present invention, and the portions corresponding to the above-described embodiments are designated by the same reference numerals and detailed description thereof will be omitted. First, the modification shown in FIG. 3 is configured such that an inverted U-shaped notch 35 is formed above the clip 25 fastening position of the supporter material 15 and a part of the supporter material 15 can be wound around the elastic member 37. It has a feature in the point. Also, a small hole 33 is formed below the clip 25 stop position, which is the same as in the above embodiment. With this configuration, if a part of the supporter material 15 is wound around the elastic member 13 and then the clip 25 is stopped,
Since the wound supporter material 15 functions as a sound deadening material, it is possible to suppress the interference sound between the elastic member 13 and the clip 25 without attaching a sound deadening material to the elastic member 13.
In addition, it is preferable to cut out the support material 15 so as to cover more than half of the outer periphery of the elastic member 13.

The modification shown in FIG. 4 is characterized in that inverted U-shaped and U-shaped notches 45a and 45b are formed above and below the clip 25 fastening position of the supporter material 15, respectively. With such a configuration as well, similarly to the above-described modification, it is possible to prevent the interference sound from being generated by a part of the supporter material 15 without separately attaching a sound deadening material to the elastic member 13. Also, it is similar to the above modification that it is preferable to cover more than half of the outer periphery of the elastic member 13 with a part of the notched supporter material 15.

[0013]

The above is the construction of one embodiment of the attachment structure of the skin material according to the present invention. According to this construction, the pulling member and the elastic member are clipped by the supporter material. It is not necessary to cut out the supporter material by providing a hole in the vicinity of the clip, and the pad material can be sufficiently protected. Further, since the supporter material is interposed between the elastic member and the pulling member, the movement of the clip can be suppressed, and the interference sound between the clip and the elastic member can be prevented without separately attaching a sound deadening material or the like. It is possible to improve the work efficiency and obtain an economical skin material mounting structure.
