A vehicle seat with an active head restraint system is provided with a
seatback frame having a pair of side members. An armature extends
transversely between the side members with a pair of lateral ends each
pivotally connected to one of the side members. A head restraint rod
extends from the armature for supporting a head restraint. An actuator is
mounted to the seatback frame for actuating the armature. A bushing is
mounted to the frame, the armature or the actuator. A rivet is mounted to
the bushing and another of the frame, armature and actuator. The rivet
preloads the bushing to minimize inadvertent movement at the connection.
A method for assembling a vehicle seat is provided wherein the bushing is
preassembled to the rivet. Another method for assembling a vehicle seat
is provided wherein the rivet preloads the bushing to minimize
inadvertent movement at the connection.
