Patent number: 8864234Abstract: A discontinuous recliner for a vehicle seat back that may be locked in a desired angular orientation. A memory function is provided by a memory pawl that is actuated by a memory handle. The memory pawl carries a memory pad in the memory disengaged position. The memory pawl carries the memory pad in a deactivated position and lodges the memory pad in internal gear teeth of a gear plate when the memory feature is activated. The memory pad rotates with the gear plate as the seat back is folded forward. When the seat back is returned to the memory position, the memory pad engages a stop on the memory pawl that is pivoted to move the memory pad out of engagement with the internal gear teeth of the gear plate.Type: GrantFiled: May 30, 2012Date of Patent: October 21, 2014Assignee: Lear CorporationInventors: Peter Robert McCulloch, James S. Wawrzyniak

Publication number: 20140008956Abstract: A continuous manual seat recliner mechanism with an integrated lock includes an upper gear plate and lower gear plate in geared connection with the upper gear plate. The upper gear plate is able to rotate eccentrically in relation to the lower gear plate. A coiled locking spring is located within a central bore of a lock cylinder which is fixed to the lower gear plate so that an outside surface of the locking spring may frictionally engage the lock cylinder to prevent the lock cylinder and, thereby, the lower gear, from rotating. The ends of the lock spring engage with a knob hub and a driver hub such that rotation of the knob hub unlocks the recliner to allow adjustment by the operator, while rotation of the driver hub locks the recliner mechanism.Type: ApplicationFiled: June 17, 2013Publication date: January 9, 2014Inventors: B. Paul Golarz, Kenneth McQueen, Robert Wahls, James S. Wawrzyniak

Patent number: 7703852Abstract: A manual vehicle seat reclining mechanism and seat assembly incorporating the reclining mechanism is disclosed. A guide plate and a pivotal plate are assembled together and disposed between the seat base and seat back. A cam is biased by a spring to hold locking elements in engagement with the pivotal plate. A control plate is manually rotated with the cam to release the locking elements by drawing pins on one side of the locking plates radially inwardly with slots provided in the control plate. Ribs are provided on the pivotal plate that prevent the locking elements from returning to the locked position in certain radial alignments of the pivotal plate relative to the guide plate.Type: GrantFiled: December 3, 2007Date of Patent: April 27, 2010Assignee: Lear CorporationInventors: Robert Wahls, James S.

Patent number: 7517021Abstract: A reclining mechanism for a vehicle seat is disclosed with a guide plate pivotally connected to a pivotal plate, which has two internal gear segments. A cam pivotally connects to the pivotal plate, and has a pair of pawls. Two lock elements cooperate with the guide plate, and have an external gear segment to cooperate with the internal gear segments. When the cam rotates, the cam engages the cam pawls with one of the engagement elements unlocking the external gear segments from the internal gear segments. Springs cooperate with the guide plate and the cam for locking the mechanism. A bushing cooperates with the cam and receives a shaft for connecting the reclining mechanism to another reclining mechanism. The cam engages each lock element at two contact points to drive the external gear segments into the internal gear segments when the reclining mechanism is in a locked position.Type: GrantFiled: November 30, 2006Date of Patent: April 14, 2009Assignee: Lear CorporationInventors: Robert Wahls, James S. Wawrzyniak, Kenneth McQueen, Luke Gajda

Patent number: 7513573Abstract: A tilt adjustment mechanism for a vehicle seat that is used to adjust the angular orientation of a seat back relative to a seat base. The tilt adjustment mechanism has a driver that has two protrusions that are rotated with the driver by a drive shaft. Initially the driver rotates independently of a cam assembly until a driving protrusion of the cam assembly is engaged. The movement of the driver continues to release a locking wedge that releases the seat back for adjustment.Type: GrantFiled: September 12, 2006Date of Patent: April 7, 2009Assignee: Lear CorporationInventors: Robert Wahls, James S.

Publication number: 20080073961Abstract: A reclining mechanism for a vehicle seat is disclosed with a guide plate pivotally connected to a pivotal plate, which has two internal gear segments. A cam is pivotally connected to the pivotal plate, and has a pair of pawls. Two lock elements are translatable relative to the guide plate, and have a gear segment to cooperate with the pivotal plate gear segments. Rotation of the cam engages each of the cam pawls with one of the engagement elements to unlock the gear segments from each of the pivotal plate gear segments. Springs cooperate with the guide plate and the cam for locking the mechanism. A bushing cooperates with the cam and receives a shaft for connecting the reclining mechanism to another reclining mechanism. A clip supports the bushing, but does not extend beyond an outer profile of one of the pivotal plate or guide plate.Type: ApplicationFiled: September 12, 2006Publication date: March 27, 2008Applicant: Lear CorporationInventors: Robert Wahls, James S.
