Abstract
A seat back structure of vehicle seat which is reduced in thickness and yet deformable to provide a deep cushiony touch to a back of passenger. According thereto, an elastic back support element and a back board element are respectively provided in one and another sides of seat back, and a movable connection element is provided so as to allow displacement of the back board element from a home position, while allowing the elastic back support element to be resiliently warped. The back board element is normally biased by a biasing element of the home position. A stopper element is defined in the seat back for preventing movement of the back board element from the home position to the elastic back support element. The back board element per se may be formed by a plurality of plate elements connected movably with one another.
