Abstract:
1. A vehicle seat with an active head restraint system comprising: a seatback frame for supporting a back of an occupant, the seatback frame having at least one cross member, and a pair of laterally spaced apart side members extending from the at least one cross member; an armature extending transversely between the pair of side members, the armature having a pair of lateral ends, each pivotally connected to the seatback frame, the armature having at least one head restraint rod extending upright therefrom and out of the seatback frame; a head restraint mounted to the at least one head restraint rod for supporting a head of an occupant; an actuator operably connected to the seatback frame and operably connected to the armature for pivoting the armature from a design position to an actuated position in response to an impact condition, thereby actuating the head restraint from the design position to the actuated position, wherein at least one of the actuator connection with the seatback frame and the actuator connection with the armature is a pivotal connection; at least one bushing mounted to a first one of the seatback frame, the armature and the actuator at one of the pivotal connections; and at least one rivet mounted to a second one of the seatback frame, the armature and the actuator at the pivotal connection with the bushing, the rivet extending through the bushing for collectively defining the pivotal connection; wherein the rivet preloads the bushing thereby minimizing inadvertent movement at the pivotal connection when the actuator is in the design position; wherein the bushing further comprises: wherein the rivet extends through the sleeve of the bushing.
