DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal treatment structure of a trim cover as a skin material in a seat back of a vehicle seat and the like. More specifically, the present invention relates to a bag-like structure for covering a pad material constituting a seat back. Wires were respectively attached to the front side and the rear side terminal of the trim cover, and the wires were locked by a locking member, and the locking member was covered by a hanging portion formed on the rear side terminal of the trim cover. The present invention relates to a terminal processing structure of a seatback trim cover.

[0002]

2. Description of the Related Art For example, a vehicle seat mounted on an automobile or the like is constituted by a seat cushion and a seat back standing upright from the back side thereof. The above-described seat cushion or seat back is generally constituted by a seat cushion frame or a seat back frame, a pad material, and a bag-like trim cover that is covered as a skin material around the pad material.

FIG. 5 shows a side cross-sectional shape of a lower portion of the seat back 3.
Is a pad material, and 6 is a trim cover. And in such a seat back 3, the trim cover 6 has been conventionally used.
Has caused a problem with the terminal processing structure.

[0004] That is, as shown in FIGS. 4 and 5, the seat back trim cover 6 has a front terminal 6a and a rear terminal 6b below the back of the seat back 3 to increase the rigidity of the respective portions. For this purpose, terminal members 7 having a double structure folded in a bag shape are sewn, and wires 8 formed of a steel wire or the like are inserted into the bag-shaped portions of the terminal members 7. Further, a fixing wire 10 is fixed to the seat back frame 4, wires 8 made of the steel wire or the like are integrally joined to the fixing wire 10 by a locking member 9 such as a hook ring, and a trim cover 6 is attached to a pad. It is assembled so as to cover the material 5.
