Abstract
A flat spring member () mainly serving as a vibration absorptive function at a normal use is engaged with a supporting frame member () which displaces backward along with deformation of a seat back () by backward moment applied to the seat back (), and the other end is engaged with a front edge frame () disposed in the vicinity of the front edge of a cushion frame. Therefore, when an impact force from front or back equal to or more than that prescribed is applied, the flat spring member () increases in tension by backward moment applied to the seat back (), and serves as a function to increase again the intensity of the backward moment of the seat back (), which was once lowered by deformation of the side frame () of the cushion frame.
