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 member 20 and a seat frame member 10 are individually formed by welding or caulking, and a link member 30 for connecting both is attached to the back frame member 20 and the seat frame member 10 by 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.
