PROBLEM TO BE SOLVED: To suppress butting of a pressure-receiving section to a webbing-fitting section, not to reduce effect that an occupant's upper body sinks rearward.SOLUTION: A back rest 4 comprises; side frames 40b; a pressure-receiving section 41 mounted as movable back and forth between the side frames 40b; an air-bag module 50 mounted at the side frame 40b; a cushion pad 48 covering the front surface of the side frame 40b and the front surface of the pressure-receiving section 41; a skin 49 covering the cushion pad 48: a webbing-fitting section 52 mounted at the side frame 40b; and webbing 51 arranged to bridge from the rear side of the skin 49 to the webbing-fitting section 52. The pressure-receiving section 41 includes a body section 41a and an extension section 41b extending from a side section of the body section 41a. The webbing-fitting section 52 is placed at such a position as to avoid a trajectory of the extension section 41b due to back-and-forth fluctuation of the pressure-receiving section 41. |
