【発明の属する技術分野】
本発明は自動車用シート（座席）などの車両用シートにおけるトリムカバーを発泡体製パッドに接着する型に関する。
【０００２】
【従来の技術】
従来、パッドにトリムカバーを加圧して、パッドの所定位置にトリムカバーを接着するには、パッドに対応するトリムカバーの位置ズレを防止するために、トリムカバーの位置決め用針を設けた型に、トリムカバーを突き刺して型に固定し、次に、このトリムカバーをパッドに加圧して接着するものがある（例えば、特願平１ー３０５０７号公報）。
【０００３】
【発明が解決しようとする課題】
この方法によると、トリムカバーを針で突き刺すことにより固定するため、トリムカバー側に針孔が開孔され、また、トリムカバーを構成する生地の繊維、糸を針で切断する虞れがある。そして、トリムカバーは加圧してパッドに接着するため、トリムカバーの加圧時にトリムカバーに張力が生じ、この張力によって前記針孔が拡大したり、針孔からトリムカバーが破損する虞れがあった。
一方、トリムカバーには身頃に対して額縁を接ぎ合わせて縫製したものがあり、このトリムカバーを裏返して加圧型に載置すると、接ぎ合わせ個所が加圧面より山形状に突出する。
そこで、本発明は加圧面に対して接ぎ合わせ個所が山形状に突出するトリムカバーを損傷することなく的確にパッドに接着し得る型を提供することを目的とする。
【０００４】
【課題を解決するための手段】
以上の目的を達成するための本発明に係るシートのトリムカバー接着型構造は、シートを構成する発泡体製パッドに、接ぎ合わせて縫製してなるトリムカバーを加圧して接着する接着型において、前記トリムカバーを載置する型の加圧面におけるトリムカバーの接ぎ合わせ個所に対応する位置に、トリムカバーの接ぎ合わせ個所に挿込むループ状の折曲してなる剛性線材製の係止部材を設けたことを特徴とするものである。
トリムカバーの接ぎ合わせ個所に、トリムカバーを裏返して載置する型に設けた係止部材が挿入されるため、トリムカバーは型の押圧面の所定位置に位置決めされる。

It is characterized by having.
Since the locking member provided on the mold on which the trim cover is turned upside down is inserted into the joint portion of the trim cover, the trim cover is positioned at a predetermined position on the pressing surface of the mold.
[0005]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a state in which the trim cover (C) is set on the lower die (L) of the press. The trim cover (C) has a frame (11) joined to the body (10). (10) and (11) are set upside down on the lower mold (L).
[0006]
As shown in FIG. 4, the lower mold (L) has a ridge (2) formed at a position corresponding to the concave groove (21) of the pad (2).
Both the body (10) and the frame (11) shown in the figure have the skin (10A) (11A), the wadding (10B) (11B) made of foam (urethane foam slab material), and the wading cover (10C) (11C). They are laminated and joined together by sewing threads (12).
[0007]
The ridge (2) is a metal plate corresponding to the length and depth of the concave groove (21) of the pad (P), and a plurality of locking members (1) ( 1) is protruded integrally.
[0008]
Each locking member (1) is bent in a loop shape from a steel wire having a circular cross section with a wire diameter of about 1 mm, and the base end is integrally welded to the ridge (2).

As shown in FIG. 3, the locking member (1) protrudes from the ridge (2) in parallel with the longitudinal direction of the ridge (2), and the trim cover (C) is mounted on the lower mold (L). When it is placed on the pad and is pressed by the upper mold (U) and bonded to the pad (P), a force in a direction perpendicular to the ridge (2) acts on the trim cover (C). The locking member (1) is formed so as not to be deformed by a force.
[0011]
Further, the locking member (1) has elasticity in the inner diameter direction, the head is formed in an enlarged shape with respect to the base fixed to the ridge (2), and the locking member (1) is trimmed (C). The trim cover (C) is easy to be inserted between the sewing threads (12) and (12) at the seaming point, and the trim cover (C) does not come off from the inserted locking member (1).
[0012]
FIG. 4 shows that the trim cover (C) is turned upside down on the lower die (L) with the pressing surface facing upward and positioned by the locking member (1) and the ridge (2), while the upper die (U) This shows a state in which the pad (P) made of a foam constituting the sheet is fixed downward and the trim cover (C) is adhered to the pad (P).
[0013]
In the trim cover (C), the joining point between the body (10) and the picture frame (11) is temporarily fixed to the lower mold (L) by fitting of the ridge (2), and is positioned, and protrudes from the ridge (2). As shown in FIG. 5, the locking member (1) is inserted into the joint of the trim cover (C), whereby the trim cover (C) is positioned and fixed to the lower mold (L).
