Abstract
A seat back framework of one-piece construction together with a head rest support is made from a single blank of fiber-reinforced plastics. The seat back framework comprises a generally rectangular body having opposite upper and lower walls, a pair of opposite side walls and a connecting wall extending between the side walls in spaced relation to the upper wall with a support space defined therebetween. A pair of guide members for axially adjustably supporting corresponding legs forming a part of the head rest assembly together with a head rest are formed on the rectangular body within the support space.
