Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to an automobile seat (seat).
The present invention relates to a bonding device for a trim cover to a foam pad in a vehicle seat.

[0002]

2. Description of the Related Art Conventionally, a device for applying pressure to a trim cover on a pad and bonding the trim cover to a predetermined position of the pad includes a positioning device for the trim cover in order to prevent a displacement of the trim cover corresponding to the pad. Some needles are provided on a mold on which a trim cover is placed (for example, see Japanese Patent Application Laid-Open No. 1-33).
No. 0507). In this method, a trim cover is fixed to a mold by piercing the trim cover with a needle, and then the trim cover is pressed and adhered to a pad.

[0003]

Accordingly, the conventional product is fixed by piercing the trim cover with a needle, so that a needle hole is opened on the trim cover side, and the fibers of the fabric constituting the trim cover are There is a risk that the thread will be cut with a needle. Then, since the trim cover is pressed and adhered to the pad, tension is generated in the trim cover when the trim cover is pressed, and the tension may cause the needle hole to expand or the trim cover to be damaged from the needle hole. there were. Then, this invention aims at eliminating the defect of the said conventional product.

[0004]

According to the present invention, there is provided a sheet trim cover bonding apparatus according to the present invention, in which a lower mold on which a trim cover is mounted is vertically mounted on a base board via a cushion material. In addition to movably provided, a slit penetrating in the vertical direction is provided at a position corresponding to the joining position of the trim cover on the pressing surface of the lower mold, and a positioning guide to be fixed upright on the base plate in this slit is provided. It is made through.

[0005]

When the upper mold is lowered and the pad abuts on the trim cover on the lower mold, the guide is first located in the joint portion of the trim cover to position the trim cover with respect to the pad. , The trim cover is bonded to the pad with an adhesive previously applied to the pad or the pressing surface of the trim cover.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a use state of the present apparatus, in which a pad (P) and trim covers (6) and (7) are set on upper presses and lower dies (1) and (2). The seat (seat cushion or seat back) is a foam molded by molding into a substantially external shape, and its seating surface (7
On the (0), (70) and (70) sides, concave grooves (71) and (71) are formed. The seating surface (70) (7) of the pad (P)
At 0), the trim covers (6) and (7) are integrally bonded with an adhesive. The pad (P) is fixed to the upper mold (1) descending by a hydraulic cylinder with a clamp or the like.

The trim covers (6) and (7) are used for the body (6).
The frames (7) and (7) are joined together, and the trim covers (6) and (7) are turned upside down and set on the lower mold (2). (60) in the figure is body (6) and frame (7)
The joints with (7) are shown. As shown in FIG. 2, the body (6) and the picture frames (7) and (7) shown in FIG. 2 are all skins (63) and (73) and waddings (62) and (72) made of foam (urethane foam slab material). , Wadding covers (61) and (71) are laminated, and (64) in the figure denotes a joining thread.

The lower mold (2) is formed such that the pressing surface (22) conforms to the shape of the seating surface (70) of the pad (P), and the concave portion of the pad (P) on the pressing surface (22). The grooves (71) and (7) are located at positions corresponding to the grooves (71) and (71).
The projection (23) that bites into 1) is provided integrally. The lower mold (2) is placed on the base (4) via cushioning materials (3) (3) (3) made of foam, spring, or the like.

A slit (21) penetrating vertically below the center of the projection (23) of the lower mold (2) is provided, and a lower end of the slit (21) stands on the base (4). The positioning guide (5) fixed in the shape is inserted. The guide (5) has a total length such that its tip slightly projects from the pressing surface of the lower mold (2) before the lower mold (2) is pressed downward.

The lower mold (2) has a trim cover (6).
When (7) is turned upside down and set, the tip of the guide (5) enters the joint (60) of the trim covers (6) and (7) as shown in FIG. Guide (5)
Is a rigid member such as metal or hard synthetic resin, the tip of which is formed sharp.

FIGS. 3 and 4 show a state in which the upper die (1) is lowered to press the pad (P) against the trim covers (6) and (7) and adhere with an adhesive. ) Is preliminarily coated with an adhesive on the back surface side or the seating surface (70) side of the pad (P).

When the pad (P) is lowered, first, the joint (60) of the trim cover (6) (7) is moved by the guide (5) so that the groove (71) (7) of the pad (P) is formed.
1) bite into. Thereby, the trim covers (6) and (7) are positioned with respect to the pad (P).
Further, when the pad (P) is lowered by the upper mold (1),
The seating surface (70) of the pad (P) is a trim cover (6)
(7) is pressed. Thereby, the trim cover (6)
Along with (7), the lower mold (7) is pressed down against the elasticity of the cushion material (3) and descends, and the trim covers (6) (7)
The pad (P) is adhered to the substrate. After bonding, the pad (P) is removed from the upper mold (1), the upper mold (1) is raised, and the pad (P) integrated with the trim cover on the lower mold (2) is attached to the lower mold (2). When the terminals of the trim covers (7) and (7), which are not detached and adhered, are folded back to the pad (P) side, the pad (P) integrated with the trim cover (6) (7) of the vehicle seat is formed. You.

[0013]

[Effects of the Invention] According to the present invention, the joining position of the trim cover is adjusted by the positioning guide provided on the lower mold.
After positioning on the pad fixed to the upper mold, the pad can be integrally bonded to the trim cover. Therefore, the trim cover can be accurately adhered to a predetermined position of the pad without damaging the trim cover as in the conventional product.
