Patent number: 9440559Abstract: A vehicle seat (1), in particular a commercial vehicle seat, includes a scissor-type (scissors) framework (3) for adjusting the height. The scissors framework has intersecting rockers (8a, 8b) and at least one frame (5, 7), and at least one bearing device (21) for movably guiding the rockers (8a, 8b) in the frame (5, 7). A rotatable bearing roller (14) interacts with a first guide and a rotatable compensation roller (36) interacts with a second guide attached to a base region (52) of an insert (60). A lateral region (54) of the insert (60) extends perpendicularly to the base region (52) and is fixed to the frame (5, 7) and/or a head region (50) of the insert (60), extending parallel to the base region (52), is fixed to the frame (5, 7). The base region (52) is resiliently designed and presses against the compensation roller (36).Type: GrantFiled: August 14, 2013Date of Patent: September 13, 2016Assignee: Johnson Controls Components GmbH & Co.

Patent number: 8641141Abstract: A vehicle seat (1), in particular commercial vehicle seat, is provided with a framework, in particular scissors-type framework (3), a seat frame (10) which is articulated thereon via a pivot axis (B), and a backrest (20) which is attached to the seat frame (10) and by means of which a torque acts about the pivot axis (B) on the seat frame (10) in the event of a crash or misuse. The framework (3) has a first catch element (31) and the seat frame (10) has a second catch element (32) which normally do not interact. In the event of a crash or misuse, the catch elements approach each other and then interact creating a further path for the force flux.Type: GrantFiled: January 23, 2008Date of Patent: February 4, 2014Assignee: KEIPER GmbH & Co.

Publication number: 20050173948Abstract: A vehicle seat includes a lower leg support fastened pivotably to a seat cushion. The lower leg support may be moved in an infinitely variable manner between a stowaway position and a position of use and may be fixed in a freely selectable position. To provide reliability against incorrect operation, the lower leg support includes an overload safeguard which releases the fixation of the lower leg support in the event of overload, thereby allowing it to give way.Type: ApplicationFiled: February 8, 2003Publication date: August 11, 2005Inventors: Michael Boehmer, Gerhard Flory, Hermann Gaus, Thomas Geisel, Thomas Gundall, Klaus Hassler, Christoph Jung, Rainer Leucht, Andreas Pieper, Thomas Weber, Boris Willems

Publication number: 20050173963Abstract: The invention relates to a vehicle seat (1) having an automatically displaceable lower leg support (3). The lower leg support can be displaced in an automatically driven fashion between a stowaway position and a position of use. In order to obtain a compact design of the vehicle seat and a high degree of protection against impact operation, the lower leg support (3) has a sensor (6, 61, 62) which is connected to a control device (52) of the drive (5). The sensor (6) is designed to detect an obstacle.Type: ApplicationFiled: February 8, 2003Publication date: August 11, 2005Inventors: Hans Edrich, Gerhard Flory, Thomas Gundall, Klaus Hassler
