  • Publication number: 20240140279
    Abstract: 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.

  • Publication number: 20230406165
    Abstract: A vehicle seat having a seat part, a backrest, a kinematics mechanism for transferring the vehicle seat from a use position to a not-in-use position, and back again, and a locking device to lock the kinematics mechanism in the use position. When the locking device is unlocked, the vehicle seat is transferred out of the use position into an access position and the kinematics mechanism is coupled to a drive device by a coupling device. The coupling device has an unlocking swing arm for at least indirectly unlocking the locking device. When in the use position of the vehicle seat, activation of the drive device first unlocks the swing arm to pivot, so that the locking device is unlocked, and it is only following the pivoting movement of the unlocking swing arm that the kinematics mechanism is driven by the drive device to transfer the vehicle seat into the not-in-use position.

  • Publication number: 20230382273
    Abstract: 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.

  • Publication number: 20170080831
    Abstract: A vehicle seat (1) is transferable from at least one use position either into an entry position or into a floor position. A seat cushion (3) and a backrest (5) are coupled by a carrier (20) to a base (10), providing kinematics (30, 40, 41, 42, 50, 53, 54) to move the carrier (20) between the use position and the entry position of the vehicle seat (1). A link (80) is coupled rotatably at one end to the seat cushion (3) and at the other end to the base (10). The seat cushion (3) is mounted on the carrier (20) by a turning and sliding joint (16, 26). At least one degree of freedom of the turning and sliding joint (16, 26) is lockable by a locking device (90). A drive, a spring, assists the transfer of the seat cushion (3) from the use position into the floor position.

  • Publication number: 20130069405
    Abstract: A vehicle seat has a base, a seat structure supporting a seat surface, and coupling elements allowing height adjusting and tilt adjusting of the seat surface relative to the base. Height is adjusted by a six-member seven-way linkage having six pivots, wherein angular orientation of two adjacent coupling elements relative to each other in a first linkage can be changed by a first fitting, and angular orientation of two adjacent coupling elements relative to each other is fixed at a second linkage by a second fitting. Angle adjustment is by the six-member seven-way linkage having six pivots, formed by the seven coupling elements. Angular orientation of two adjacent coupling elements relative to each other at the first linkage can be set via the first fitting, and angular orientation of two adjacent coupling elements relative to each other at the second linkage can be changed by the second fitting.
