PROBLEM TO BE SOLVED: To solve a problem that the number of part items of a constitution which locks a holding stand at an erecting position is large, and the constitution is inevitably complicated.SOLUTION: A foldable holding stand 30 is erected at a normal time, and holds a seat cushion 14 substantially horizontally. The holding stand is formed into a substantially-inverted U-shape having a connecting part 30b for connecting a pair of legs 30a and upper ends of the legs. Lower ends of a pair of the legs are connected to lower ends of a pair of support links 30c by pins 30c-p so as to be turnable. A connecting rod 30d is fused to upper ends of a pair of the support links, bridged between the support links, and fused to a tip of a side frames 11S of a riser. Legs of a pair of the connecting links 30e are connected to a side frame 12S of a seat back by pins 30e-p1 so as to be turnable, and maintain the holding stand at the erecting position at a normal time, and the holding stand is folded in conjunction with a front fall of the seat back.SELECTED DRAWING: Figure 2 |
