  • Patent number: 9440559
    Abstract: 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).

  • Patent number: 8641141
    Abstract: 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.

  • Patent number: 8544813
    Abstract: A vehicle seat, particularly a commercial-vehicle seat is provided with a scissor-type stand (3) which is able to vibrate and which is provided with a top frame (7), two first rocker arms (8a) and two second rocker arms (8b), which intersect in pairs at a scissor axis (10) extending in a transverse seat direction (y). The first two rocker arms (8a) are connected with one another at one end via a transverse tube (18) which extends in the transverse seat direction (y) and are pivotably mounted on the top frame (7) and able to vibrate in the longitudinal seat direction (x) via a bearing mechanism (20). The transverse tube (18) can be locked with the top frame (7) via at least one locking device (31).

  • Patent number: 7497517
    Abstract: Vehicle seat, in particular a motor vehicle seat, with a seat part (3) that is linked to a support via a cushion-four-joint (42), a backrest that can be tilted and locked by at least one fitting and which is linked to the cushion-four-joint (42) through a link-four-joint (48), in which a linking member (41) is a common component of both four-joints (42, 48), wherein the vehicle seat at a minimum can be converted from at least one in-use position that is suited for passenger transport, to a folded together, not-in-use position, and between the seat part (3) and the support an additional securing device with leeway (53) is provided in the in-use position, wherein the leeway (53) defines the mobility of the cushion-four-joint (42) in the case of a crash and during a forward tilt adjustment of the backrest.

  • Publication number: 20050173963
    Abstract: 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.

  • Publication number: 20050173948
    Abstract: 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.
