ACTUATOR FOR CRASH ACTIVATED HEAD RESTRAINT
First Claim
1. Vehicle-seat comprising a seat base, a seatback and a head restraint located at the upper end of the seatback, said head restraint being a crash activated head restraint, which reduces the gap between the head of a seat occupant and the front side of the head restraint in case of a rear crash, the vehicle seat further comprising an actuator, which is located in the seat back, which comprises a deformable body, which deforms reversible under the force resulting from the rearward movement of body of the seat occupant during and/or after the rear crash, and which comprises a first and a second end, whereas at least one end, preferably both ends, is/are slideably supported in a basis, whereas the head restraint and the actuator are connected by a force transmitter, which transmits a force, resulting from the deformation of the deformable body from the actuator to the head restraint.
