Patent number: 10598475Abstract: A production line a first conveyor for advancing assembled vehicle seats to a checking station and a second conveyor for advancing each of the checked seats to a subsequent station, the nature of the subsequent station depending on as-built coordinates relating to each of the vehicle seats and determined by the checking station. The checking station includes a displacement mechanism and a detector. The displacement mechanism displaces a hip point fixture between a first standby position and a second test position in which the hip point fixture is depressed into each of the vehicle seats to simulate a load. The detector determines the as-built coordinates, at least one such as-built coordinate being determined from a location on the hip point fixture.Type: GrantFiled: December 14, 2017Date of Patent: March 24, 2020Assignee: Lear CorporationInventors: Sai Prasad Jammalamadaka, Nick Roelli, Larry Bruck

Patent number: 9457699Abstract: A seat assembly having an automatically adjustable head restraint is provided. A seat back is mounted within a vehicle and a head restraint assembly is adjustably mounted to the vehicle and disposed adjacent the seat back. The seat back includes a sensor mounted adjacent an upper portion of the seat back for detecting the presence and position of a passenger relative to the head restraint. A controller is in communication with the sensor and receives the output signal of the sensor. The controller then generates a control signal in order to position the head restraint based on the output signals of the sensor. An actuator is connected to the head restraint for positioning the head restraint based on a control signal received from the control module.Type: GrantFiled: March 16, 2011Date of Patent: October 4, 2016Assignee: LEAR CORPORATIONInventors: Arjun Yetukuri, David A.

Patent number: 8231177Abstract: A foldable head restraint assembly includes a mounting subassembly, a structural shell, and a locking plate. The mounting subassembly supports the structural shell and includes a first support post, a second support post, a cross member, and a latch rigidly. The cross member is attached to the first and second support posts and to the latch. The folding motion of the head restraint is initiated by movement of the locking plate which is positionable at a first plate position for engaging the latch and at a second plate position for releasing the latch. The structural shell is pivotable about the mounting subassembly when the latch plate is in the second plate position.Type: GrantFiled: May 7, 2010Date of Patent: July 31, 2012Assignee: Lear CorporationInventors: Sai Prasad Jammalamadaka, Arjun V.
