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 elastically and reversibly under the force resulting from the rearward movement of a body of the seat occupant during and/or after the rear crash, and which comprises a first and a second end, wherein at least one end, is slideably supported in a basis, wherein 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, wherein the deformable body is a plate, wherein plate has an initial shape that is generally convex from the first end to the second end, and wherein the plate is an elastically bended plate which is flattened during deformation and returns to the initial shape during or after the rear crash.
