Beschreibung
Zusammenfassung:	A seat back supporting mechanism (5) for movably supporting a seat back (3) on support members (15) is provided such that a load exerted on the seat back (3) by a passenger's waist part upon a rear crash of a vehicle causes a rotation of the entire seat back (3) from its usual position about its instantaneous center (5a to 5g) located above the load exerting position, thereby moving a head rest (4) forward and upward. This seat back supporting mechanism (5) is constructed to move the instantaneous center (5a to 5g) of the seat back (3) upward and forward as the seat back (3) rotates. The passenger's head can be effectively received upon the rear crash of the vehicle by moving the head rest (4) forward and upward.
