Abstract
In a control system for a head restraint adjustably mounted on an automotive seat with the provision of a load-sensitive switch in the seat and a reversible motor responsive to the action of the switch, a switching circuit comprises a device having a pair of conductors fixed to a rotatable member coupled with the reversible motor and a set of stationary contacts arranged to individually make sliding contact with at least one of the conductors. The position of the stationary contacts is adjustable, and the head restraint is automatically lifted upon occupation of the seat by a passenger to a position determined by the position of this contact. The control system includes a selector switch to enable manual control of the action of the motor so as to move the head restraint from the automatically lifted position.
