Abstract
Head restraint supporting structure of the present invention is such that a head restraint bracket supporting a head restraint is secured to a seat back frame, a stay of the head restraint being inserted into the head restraint bracket. Wherein the head restraint bracket is formed into a tubular shape by joining two end portions of a plate material having been bent, and is secured to the front face of the seat back frame so that junction between the two end portions abuts against the seat back frame. A reinforcement structure is formed at the upper end of the junction. This reinforcement structure prevents the upper end of the junction from being opened by a load being applied to the head restraint, thereby allowing the head restraint 9 to restrain reliably the rearward movement of occupant's head and hence to reliably protect the occupant's neck.
