Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trim cover assembly used for each part of a seat such as a seat back, a seat cushion, a headrest, or an armrest, and particularly, the mounting work is easy and an occupant sitting on the seat is injured. It's about a safe trim cover assembly.

[0002]

2. Description of the Related Art A trim cover assembly covers a surface of each part of a seat such as a seat back, a seat cushion, a headrest or an armrest.
Both ends of the trim cover assembly are stopped by hog rings or the like, and the trim cover assembly is attached to each part of the seat.

For example, as shown in FIG. 5, the trim cover assembly 71 of the seat back 70 includes a seat back 7
It is stopped at 0. The upper drawing of FIG. 5 is a cross-sectional view of the circular portion of the seat back 70 shown below.

A trim cross lower front 73 and a trim cross lower rear 74 are double-folded and sewn to the tip of the outer skin 72, and the trim cross lower front 73 and the trim cross lower rear 74 are respectively sewn.
Two trimming wires 75 and 76 are inserted in each of them. This trimming wire 75,
76 are secured to each other by a plurality of hog rings 77,
A trim cover assembly 71 is attached to the surface of the seat back 70 so as to cover the seat pad 78.

The hog ring 77 is a wire, which has been cut into a C shape in advance, is formed into a ring shape by a mounting tool. Therefore, both ends of the hog ring 77 are sharp. Therefore, it is dangerous for both ends of the hog ring 77 to project to the outside of the seat back 70. Therefore, as shown in FIG. 5, both ends are stopped so as not to project.

[0006]

However, when the hog ring 77 is mounted using a worn mounting tool, or when the hog ring 77 is mounted in a diagonal direction at a position where the mounting interval is large, as shown in FIG. Both ends 77 of the attached hog ring 77 as shown in a).
Sometimes a was protruding. The hog ring 77 having both ends 77a projected may be gradually rotated when the seat is used, and the both ends 77a may project outside the seat back 70 as shown in FIG. 6B. Both ends (tips) 77 of the hog ring 77 protruding to the outside
If a passenger sitting in the seat accidentally touches a, the tip 7
There is a risk of catching 7a and getting injured. Therefore,
If the trim cover assembly 71 is stopped while the tip 77a of the hog ring 77 is protruding, the hog ring 77 must be temporarily removed, and the trim cover assembly 71 must be stopped again with another hog ring 77. was there.

By the way, a J trap may be used instead of the hog ring 77 to attach the trim cover assembly to the surface of each portion of the seat such as the seat back. This is shown in FIG. 7 (a) and 7 (b),
FIG. 3 is a diagram showing a trim cover assembly used for a seat back. For ease of understanding, these show the engagement state of the trim cover assembly from above, excluding other members used for a seat back such as a seat pad. 7A shows a state before engagement (before attachment) of the trim cover assembly, and FIG.
(B) shows the state after the engagement (after the attachment).

The trim cover assembly 91 is attached to the surface of the seat back or the like by engaging the J-traps 93 and 94 sewn on the skin 92 with each other. Since the J-traps 93 and 94 overlap each other and engage with each other, unless the engagement is released, the hog ring 7
As in the case of No. 7, the J-traps 93 and 94 do not project to the outside of the seat back.

However, the J-trap 93, 94
There is a problem in that it is very difficult for an operator to perform this engagement work many times a day on the sheet production line because a large force is required to engage the. That is, as shown in FIG.
To engage four, either or both skins 92
8 to pull out the J-trap 9 as shown in Fig. 8 (a).
It was necessary to overlap 3, 94 more than the engagement position by the width C or more. The J-traps 93, 94 are continuous plate-shaped members formed by extrusion molding, and are sewn to almost one end of the trim cover assembly 91. Therefore, in order to pull the J-traps 93 and 94, one end of the trim cover assembly 91 must be pulled. Therefore, overlapping the J-traps 93 and 94 by more than the width C than the engaging position requires a very large force. I needed it. Therefore, for workers who repeat the same work many times a day, this J-trap 9
The work of engaging the 3,94 has been a difficult work.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a safe trim cover assembly that is easy to install and does not injure an occupant sitting on a seat. Has an aim.
