- a force is applied either to a main seat body 24 or at a location within the main seat body 24 and is transmitted to a head rest 20.
- the transmitted force preferably actuates the head rest 20 causing it to move to a position that is beneficial to a user or occupant of the seat.
- the head rest 20 is connected to a housing 22.
- the housing may be directly or indirectly connected to the main seat body 24.
- a head rest Bowden cable 50 is connected to one side of a cable terminal 26 together with a first bolster Bowden cable 28 and a second bolster Bowden cable 30.
- a folding seat Bowden cable 32 is connected to the cable terminal 26 on the other side.
- a termination block (not shown) is preferably situated within the cable terminal 26.
- Each of the four Bowden cables 28, 30, 32, 50 connected to the cable terminal 26 comprise a termination bullet (not shown) that is disposed in a hole in the termination block.
- the termination block may be provided with a track that compliments a track within cable terminal for traveling longitudinally within cable terminal 26.
- the termination block is preferably provided with thirty-five (35) millimeters of longitudinal travel within cable terminal.
- the folding seat Bowden cable 32 is terminated at another end at a stationary point 34.
- the stationary point 34 may be located at numerous points outside of a back portion of the main seat body 24.
- the stationary point 34 is selected such that when, the back portion of the main seat body 24 is pivoted from a vertical position to a folded, horizontal position, distance between the stationary point 34 and the folding seat Bowden cable conduit 36 is increased. In this manner tension is applied to the folding seat Bowden cable wire 38 when the seat is folded down.
- the termination block within cable terminal 26 is pulled towards the folding seat Bowden cable 32, and is pulled away from head rest Bowden cable 50, first bolster Bowden cable 28, and second bolster Bowden cable 30.
- the cable terminal 26 end of the head rest Bowden cable 50 is pulled, the other end of the head rest release Bowden cable 50 actuates the head rest 20.
- the first and second bolster Bowden cables 28, 30 provide an actuating force to first and second lateral bolsters 40, 42. It is within the scope of the invention that multiple other Bowden cables could be attached to the cable terminal 26 and used to actuate other devices, such as a lumbar support in a similar manner.
- the head rest 20 end of the head rest Bowden cable 50 is attached to a latch mechanism in head rest (not shown).
- the latch mechanism may release the head rest 20 to assume a folding forwards position or a folding backwards position.
- There may also be combined a telescoping release function wherein the head rest is released from its extended telescoped position in conjunction with either folding forwards or folding backwards.
- the head rest latch mechanism may operate in numerous ways.
- the latch mechanism may release a wound coil spring. Releasing the wound coil spring will allow the spring to unwind and to torque the head rest into either a folding forwards position or a folding backwards position. The spring may be re-wound by the raising of the seat back frame to the upright position.
- the head rest end of the head rest Bowden cable 50 may pull the head rest 20 towards a folding forwards position or a folding backwards position.
- a spring opposes the folding motion of the headrest such that when the back portion of the main seat body is returned from a folded, horizontal position to a vertical position and the tension on the head rest Bowden cable 50 is reduced, the spring returns the head rest 20 to an unfolded, upright position.

- the Bowden cable also preferably has a first conduit portion 234 between the actuator 224 and a first side of the basket
- the ends of the first and second conduit portions 234, 236 connected at their respective sides of the basket 220 are preferably connected directly to the respective guide wires 222 or in such a manner that force applied to the ends of the conduits 234, 236 is transmitted to the respective guide wires 222 with little or no transmission of force through the basket 220.
- the Bowden cable 230 is arranged as shown in Figure 9, such that when the actuator 224 pulls the Bowden cable wire 232, the basket 220 is pulled towards the lumbar region of an occupant of the seat. However, pressure applied to the basket 220 results in increased tension in the Bowden cable wire 232. As tension in the Bowden cable wire 232 increases, a greater force is applied to the actuating mechanism in the head rest 20. The actuating
