Links(20R,20F) are provided, each between one of the side frames(14-1) of the seat cushion(14) and the support member(22), and can be swung. A band(18) extends at a substantially center part of the seat cushion(14) and between the side frames(14-1), and is provided beneath the seat pad(14-2). One end(18a) of the band(18) is secured to the top of one side frame(14-1), and the other end (free end; 18b) hangs over the top of the other side frame(14-1). The free end(18b) of the band(18) further extends via the direction changing member(14-1a) provided on the side frame(14-1), first passing by a first relay point, i.e., the axle(20R-1) of the link(20R) provided on the side frame(14-1), and then passing by a second relay point, i.e., the axle(20R-2) of the link(20R) provided on the support member(22). At an emergency, the traction device(30) pulls and stretches the band(18). |
