ABSTRACT:
A motor vehicle seat is disclosed which can pivot with respect to its underframe in a predetermined direction about a rear axis a transverse direction extending perpendicularly to the travel direction of the vehicle. The seat is supported on the underframe by means of a front deformation element arranged at a distance from the rear axis. The deformation element serves to lessen the severity of injury to person colliding with the seat backrest from behind. The deformation element is designed as a foamed material block surrounded by a shell. The upper and lower shell surfaces of the shell are respectively provided with fastening devices for fixing to the underside of the seat and to the underframe. The shell has predetermined bending sections which form the folding lines during pivoting of the motor vehicle seat caused by an accident.
