Motor vehicle seat e.g. front seat, adjustment device, has one motor device generating simultaneous translation movement of pins and another motor device generating relative rotation movement of head rest with respect to back rest base

摘要

The device has a seat head rest with a rigid structure and a seat back rest with a base (14). A motor device (16) is adapted to generate a simultaneous translation movement of two parallel pins (4, 5) mounted on the base. A motor device (19) being distinct from the motor device (16) is adapted to generate a relative rotation movement of the structure with respect to the base.
