しくない。 A possible way to prevent it from floating up is to glue and fix the back pad to the back frame.
This is not preferable because it increases assembly man-hours and costs.

に保持することができるようになる。Function: In this seat bag assembly structure, the end of the lining material attached to the back of the back pad is wrapped around the lower part of the back frame and fixed, and the back pad is held on the back frame by the lining material, so the structure is extremely simple. Moreover, the seat bag can be held securely in a predetermined position.

実施例以下、第１，２図を参照して説明すれば、次の
通りである。Embodiment The following will be described with reference to FIGS. 1 and 2.

る。 The back pad 10 is covered with a backing material 11 made of nonwoven fabric or the like on the back side to prevent cracks or abnormalities from occurring due to contact with the back frame. A concave portion 12 is formed by concave together with the backing material 11. The back frame is provided with a plurality of protrusions 21 that stand upward from the lower part 20 and are mounted on the axis at desired intervals, and these protrusions 21 can latch and support the end of the backing material 11. There is.

The recess 12 is fitted into the lower part 20 and the backing material 11 is inserted into the lower part 2 from below the recess 12.
It is assembled by winding the terminal into the 0 and hooking the terminal to the protruding piece 21 that stands upward. In this state, the back pad 10 is fitted and locked into the lower part 20 in the recess 12, and is also pulled downward by the backing material 11, so that the seat back B is supported at a predetermined position on the back frame. become.
