Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a seat back of an automobile seat (seat), specifically, the center of the seating surface side. A seat back body that has a recessed part, and a seatback that fits into the recessed part of the seatback main body. In a seat back consisting of a seating body that is fixed by Related to a structure for attaching to the body.

0002

[Conventional technology]

Some conventional automobile seats have a structure as shown in FIG. This is applied to the seating surface of the seat back (SB) against the seat back body (1). A separately molded seating body (2) is provided, and this seating body (2) is the seat back body. A foam cushion body with excellent cushioning properties is used for the cushion body in (1). This improves the cushioning properties of the seating surface of the seat back (SB). In the figure, (HR) indicates a headrest, and (H) indicates a through hole.

0003 Figure 7 shows the state before the above seating body (2) is fixed to the seat back body (1). The seat back body (1) is made of a frame (1) made by bending a metal pipe into a frame shape. 1), a spring material (not shown) stretched between the left and right side parts of this frame (11), and a spring material A foam cushion body (12) supported by a spring material, and this cushion body (11) The front side of the cushion body (11) is composed of a skin material (13) that covers the The center part except the left and right sides is formed in a concave shape. In the figure, (1a) and (1a) are The raised parts (1b) on the left and right sides of the back body (1) are the raised parts (1a) ( 1a) Shows the recessed portion between. And, between the left and right side parts of the frame (11), on the upper left and right sides of the recessed part (1b), The L-shaped hooks (14) (14) are attached to a mounting rod (not shown) with both ends welded to the exposed. In the figure, (15) indicates a tongue hanging from the lower end of the epidermis.

0004 On the other hand, the seating body (2) has an outer surface that fits into the recess (1b) of the seat back body (1). A foam (slab material) cushion body (22) having a shape and this cushion A skin material (23) that covers the body (22) and a frame embedded in the cushion body (22). insert wire (21), and this insert wire (21) with longitudinal direction. Both ends are fixed, a part of which protrudes from the outside, and is hooked to the hooks (14) (14). It consists of latching wires (24) (24). and the skin material A tongue-shaped binding portion (25) extends from the lower end of (23).

[0005] Therefore, the seating body (2) is fitted into the recess (1b) of the seat back body (1). Then, connect the latching wires (24) (24) of the seating body (2) to the flap of the seat back body (1). hook (14) (14) and connect the binding part (25) of the seating body (2) and the seat back. By binding the tongue piece (15) of the hook body (1) together with a hog ring, etc., The seating body (2) is fixed to the seat back body (1), and the seat back (2) shown in FIG. SB) is formed.

[0006]

[Problem that the idea aims to solve]

The hook (14) provided on the seat back body (1) above is directed toward the seated body (2). It is formed in an L-shape with the tip protruding horizontally and bent upward at a right angle. The latching wire (24) that is latched to the hook (14) is bent into a U-shape and is seated. It protrudes horizontally from the back surface of the body (2). Therefore, when a rearward load is applied to the upper part of the seated body (2) as the seated person sits down, The latching wire (24) moves in the front-back direction with respect to the hook (14). Therefore , since the upper part of the seating body (2) moves back and forth, the seat back body of the seating body (2) There was a defect in (1) that seriously affected the ease of installation. Therefore, the purpose of this invention is to eliminate such defects of conventional products. . That is, the object is to improve the ease of attaching the seating body to the seat back body.

[0007]

[Means to solve the problem]

In order to achieve the above objectives, the present invention is designed to protrude approximately horizontally, and the seat back The hooks on the left and right sides of the main unit are bent into a U-shape, and the hooks on the left and right sides are It is provided integrally between the retaining parts, and is bent perpendicularly to the retaining part to form a concave part in the seat back body. A wire consisting of a support part that comes into contact with the inner surface of the seat is made to protrude from the back surface of the seating body. It is something.

[0008]

[Effect]

Attach the hook part of the wire that protrudes from the back of the seat to the hook on the seat back body side. If a rear load is applied to the hook while the hook is hooked, the support will be Since a reaction force acts in the direction, the wire does not move back and forth.

[0009]

【Example】

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 5. Figure 1 shows the state before the seating body (2) is attached to the seat back body (1) side. A clip (3) is attached to the frame-shaped insert wire (21) embedded in the seating body (2). 6) The annular wire (3) is tied together by (36), and the wire (3) is tied together. It is securely fixed to the insert wire (21). The wire (3) is exposed to the outside from the back surface of the seating body (2) as shown in Figures 3 and 4. The support provided between the hanging parts (31) (31) and the left and right hanging parts (31) (31) It is embedded in the holding part (32) and the foam cushion body (22) of the seating body (2). It is composed of buried parts (33), (34), (35), and (36).

0010 The left and right hooking parts (31) (31) of the above wire (3) are located on the back side of the seating body (2). It protrudes more horizontally and hangs on the hooks (14) (14) of the seat back body (1). It is bent into a U-shape so that it can be stopped. Moreover, the support part (32) of the wire (3) is located between the left and right hook parts (31) (31). It is bent approximately at right angles to the latching portions (31) (31), as shown in Figure 5. In the state where the hooks (31) (31) are hooked to the hooks (14) (14), The seat back body (1) is configured so as to come into contact with the inner surface of the concave portion (1b) of the seat back body (1). Ru. Furthermore, the buried portion (33) is located within the cushion body (22) as an insert warp. are integrally tied to the ear (21) with the clips (36) (36) as described above, and It is bent in the same direction as the support part (32).

[0011] The hooks (14) (14) of the seat back body (1) are recessed as shown in Figure 2. The recessed part (1b) is exposed to the outside in an L-shape through the notches (16) provided on the left and right sides of the upper part. , locking claws (14a) on the left and right sides of the upright part of this hook (14) (14) (14a) is provided to prevent the hook (31) hooked to the hook (14) from coming off. ing. In addition, a bead (14b) is provided at the center of the hook (14) in the width direction, The hook (14) itself is reinforced.

0012 In this way, as shown in Fig. 5, the seatback body (1) is seated on the hook (14). When the wire hooking part (31) on the body (2) side is hooked, it is integrated with this hooking part (31). The support portion (32) contacts the inner surface of the recessed portion (1b) on the seat back body (1) side. . Therefore, when a load is applied to the seat body (2) in the direction of the seat back body (1), , a rearward load acts on the hook part (31), but a force in the opposite direction to this load acts on the support part (31). 2), the seating body (2) is moved in the direction of the seat back body (1) by the load. never moves.

[0013]

【effect】

According to the present invention, the seat back body is connected between the latching wires provided on the conventional seating body side. By simply providing a support portion that comes into contact with the inner surface of the concave portion of the The upper part of the seating body does not move back and forth.
