VEHICLE SEAT

摘要

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