ABSTRACT:
The object of the present invention is to suppress rebound of a human body when receiving a large impact load accompanying a collision or the like. A back frame member20and a seat frame member10are individually formed by welding or caulking, and a link member30for connecting both is attached to the back frame member20and the seat frame member10by welding or caulking. Each of the frame members is provided with a cushioning member as a tension structure. Upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the tension of the cushioning member provided as the tension structure lowers to be able to exhibit high damping characteristics.
