A vehicle seat headrest assembly () includes a headrest () having a rear headrest portion () with a housing () mounted on vertical posts () for vertical movement and also includes a front headrest portion () having a housing () movable longitudinally in forward and rearward directions by a support linkage () under the control of a rack and pinion mechanism (). A first helical spring locking clamp () permits upward adjusting movement of the headrest but normally prevents downward movement, and a second helical spring locking clamp () permits forward movement of the front headrest portion housing () while normally preventing rearward movement. An actuator () releases the first and second helical spring locking clamps (and) to permit downward movement of the headrest () and rearward adjustment of the front headrest portion () housing ().

Vehicle seat headrest assembly having vertical and longitudinal adjustment

A vehicle seat headrest () is mounted on a vehicle seat back () for infinite position vertical adjustment by helical spring clamping and unclamping of a support shaft of the headrest.

Adjustable positioner for vehicle seat back headrest

A vehicle armrest positioning assembly () for adjustably positioning a vehicle armrest () on a vehicle seat frame () includes an elongated adjuster () that provides armrest positioning and is released by a release actuator () a release mechanism () to permit angular adjustment of the armrest positioning. The adjuster () includes a housing () that positions an adjusting rod () by a helical lock spring () to control the armrest positioning and adjustment.

Vehicle armrest positioning assembly

A vehicle armrest assembly () includes an armrest (), a ratchet mechanism () having a linear ratchet plate () that cooperates with a pawl locking assembly () to permit vertical adjustment of the armrest. An upper armrest portion () is mounted on an armrest housing () by a track () for adjustable movement. An adjuster () of the armrest permits pivotal adjustment of the armrest as well as pivoting to a nonuse position.

Vehicle seat armrest assembly

A vehicle foldable seat back recliner () is operable to permit movement of a foldable vehicle seat () so that its seat bottom () and seat back () store in either a folded vertical position or a folded horizontal position.

Recliner for vehicle foldable seat

A vehicle seat support frame assembly () has a seat cushion base member () with opposite ends () and () pivotally connected to first and second legs (). The first legs () are also pivotally connected to the associated vehicle and the second legs () have first and second latches () and (). Each first latch () provides securement of the associated second leg to the associated vehicle in the seating position, and each second latch () prevents pivoting between the second leg and the seat cushion base member end () to provide rigidity in the seating position.

Vehicle seat support frame assembly

A vehicle seat attachment latch assembly () includes a latch () mounted for movement between latched and unlatched positions with respect to a striker () to secure and selectively release a vehicle seat with respect to a vehicle body. A latching wedge () is mounted on the latch () for movement therewith and for movement with respect thereto in cooperation with a bias () provided by a first spring () that moves a wedging surfaceof the latching wedge () into wedging contact with the striker () with the latch () in its latched position in order to provide a rattle free attachment. A locking pawl () and a spring () cooperate to hold the latch () in its latched position or permit release thereof for movement to the unlatched position where the striker () is released.

Vehicle seat attachment latch assembly

A vehicle seat back recliner assembly () includes a pair of recliners () each of which has a locking mechanism () including an operator () having a control lever () that pivots in opposite directions to provide recliner locking and unlocking. The control lever is pivoted in one direction to move a pair of toothed pawls () through a pair of cams () to provide locking, and the control lever is pivoted in the other direction to move the cams so as to permit movement of the pawls for the unlocking and to also move the pawls from the locking positions to the unlocked positions to permit recliner adjustment. A release mechanism () of the recliner assembly includes a release actuator () and a cable assembly () that insure unlocking of both recliners () upon an unlocking actuation.

Vehicle seat back recliner and assembly

A vehicle seat back recliner () includes a locking mechanism () having a pair of toothed pawls () and a pair of cams () operated by a control () to provide locking and release between a stationary seat cushion mounted member () and a pivotal seat back member (). A spring () of the control () biases the locking mechanism to a locked condition and upon release springs () move the toothed pawls () out of engagement with the toothed locking ring () to permit pivotal adjustment of the seat back member (). In one embodiment, the cams () move in rectilinear directions and have flat actuating surfaces engaged with flat actuating surfaces of the pawls, while another embodiment has the cams (') moved in curved paths and having curved actuating surfaces slidably engaged with curved actuating surfaces of the pawls.

Vehicle seat back recliner

A vehicle seat back recliner () includes a lock mechanism () having a locking pawl () for locking a seat back pivotal bracket () against pivoting with respect to a seat cushion stationary bracket () under the operation of an associated control cam () and a locking pawl catch (). The catch () holds the locking pawl () in an unlocked position until the seat back is pivoted upwardly from a horizontal cargo position to an upright use position whereupon the catch releases the locking pawl and the control cam () maintains the locking pawl in its locked position. Pivoting of the control cam () against a spring bias provides release of the locking pawl () to permit seat back pivoting from a upright use position to the horizontal cargo position.
