Patent number: 12617320Abstract: A vehicle seat may have a seat part which can be moved from a usage position into a non-usage position, a seat back, a base, and a seat kinematics connecting the seat part pivotably to the base. The seat kinematics may have a rocker which by a first rotary joint is deflected pivotably on an adapter connected to the base and by a second rotary joint is deflected pivotably on the seat part. A spacing between the base and the seat part can be changed by selection of a first articulation point for articulation of the first pivot joint on the adapter fixedly connected to the base, and/or by selection of a second articulation point for articulation of the second pivot joint on the seat part. A method for assembling such a vehicle seat is also provided.Type: GrantFiled: March 10, 2022Date of Patent: May 5, 2026Assignee: Adient US LLCInventors: Joachim Kaemmerer, Gregor Lubczyk, Markus Weber, Ralph Recktenwald, Holger Kunz

Patent number: 12600268Abstract: A vehicle seat having a seat part, a backrest, a kinematics system for transferring the vehicle seat from a use position into an entry position and back, a drive apparatus for driving the kinematics system, and a coupling apparatus for coupling the drive apparatus to the kinematics system. The coupling apparatus has a pawl and a counter-element. The pawl and the counter-element are locked to one another in order to couple the drive apparatus to the kinematics system, wherein the pawl is released from the counter-element by an actuation of the coupling apparatus, resulting in the drive apparatus being decoupled from the kinematics system. The pawl is configured as a bracing pawl, and the pawl and the counter-element are locked to one another beyond a self-locking action.Type: GrantFiled: October 28, 2021Date of Patent: April 14, 2026Assignee: Adient US LLCInventors: Joachim Kaemmerer, Ralph Recktenwald, Holger Kunz

Patent number: 9592749Abstract: A vehicle seat has a basic structure, a backrest support which is articulated on the basic structure in a lockable manner by at least one fitting, a backrest structure a backrest that has the backrest support and the backrest structure, the backrest being movable in relation to the basic structure by a kinematic system in order to transfer the vehicle seat from at least one use position, in which it can be sat on, into an out-of-use position or into a further use position and back again. A four-bar linkage temporarily exists the four-bar linkage controlling the kinematic system.Type: GrantFiled: July 19, 2012Date of Patent: March 14, 2017Assignee: KEIPER GMBH & CO.

Patent number: 9290116Abstract: The invention relates to an actuator (71) for a vehicle seat, comprising a handle (41) for jointly actuating two locks (23), a force transfer between the handle and each lock, a first indicator (51) associated with the first force transfer, and a second indicator associated with the second force transfer, wherein the two indicators each indicate the respective locking status of the associated lock, and the two indicators actuate an overall indicator (61) by means of a logical OR function in order to visibly indicate the unlocked state. The force transfer is preferably formed from Bowden cables (43).Type: GrantFiled: February 3, 2012Date of Patent: March 22, 2016Assignee: KEIPER GMBH & CO. KGInventors: Ingo Teufel, Joachim Kämmerer, Ralph Recktenwald

Patent number: 9145071Abstract: A vehicle seat, in particular to a motor vehicle seat, having a base structure (3) that is to be connected to the vehicle structure (S) and a backrest (10) that can be moved relative to the base structure (3) by kinematics, such as to transfer the vehicle seat (1) from at least one usage position allowing a person to sit down to a non-usage position or to another usage position. A multi-bar linkage, in particular a four-bar linkage (V), exists at least temporarily, which linkage controls the kinematics. A leaf spring (30) is provided in the vehicle seat. The leaf spring forms a gear element of the multi-bar linkage in the relaxed extended state thereof.Type: GrantFiled: April 18, 2012Date of Patent: September 29, 2015Assignee: KEIPER GmbH & Co. KGInventors: Andre Böhm, Ralph Recktenwald
