  • Patent number: 8186758
    Abstract: An automobile seat is provided that includes, but is not limited to a backrest, a seat portion, a backrest pivoting mechanism, and a two-link seat-portion pivoting mechanism. The seat portion is fastened to the backrest or the backrest pivoting mechanism so that it is pivotable about a first transverse axis and the backrest is fastened to the backrest pivoting mechanism so that it is pivotable about a second transverse axis, so that the backrest may be pivoted from a usage position in which the seat portion adopts a first position, forward about the second transverse axis into a non-usage position, in which the seat portion occupies a second position, in which the seat portion is displaced rearward with respect to the first position. The backrest pivoting mechanism is a four-link backrest pivoting mechanism, which is configured in such a manner that the second transverse axis may be displaced rearward into the non-usage position by pivoting the backrest.

  • Patent number: 7992914
    Abstract: A seat arrangement is provided for an automobile comprising a vehicle seat, a longitudinal guide for displacement of the vehicle seat in the longitudinal direction, and a transverse guide for displacement of the vehicle seat in the transverse direction. A forced guidance is furthermore provided, this being configured in such a manner that during displacement in the longitudinal or transverse direction, the vehicle seat is automatically also displaced in the transverse or longitudinal direction.

  • Patent number: 7988229
    Abstract: A vehicle seat arrangement (1) is provided including a seat structure divided, in a transversal direction, into an outer first seat (11), a middle second seat (12), and an outer third seat (13), which can all be moved in a longitudinal direction in relation to the vehicle structure and can be locked therewith. The arrangement is provided with a coupling device (20) which couples the second seat (12) to one of the two outer seats (11, 13), forming a pair, when the other of the two outer seats (11, 13) is moved in relation to the pair in the longitudinal direction.

  • Publication number: 20110139954
    Abstract: A longitudinal adjuster for a vehicle seat (1) with a spindle (13), which is arranged in a hollow space formed by a pair of rails (5, 7), and with spindle holders (15). The area of connection of at least one of the spindle holders (15a) to one of the rails (5) lies outside of the hollow space formed by the rails (5, 7). The spindle holder (15a) extends with a partial area, with which it is connected to an end (13a) of the spindle (13), into the hollow space.

  • Publication number: 20090236885
    Abstract: A seat arrangement is provided that includes, but is not limited to a first and a second vehicle seat, which are disposed adjacent to one another in a seat row and of which the first vehicle seat has a backrest, which can be pivoted from a substantially upright usage position in the seat direction forward into a substantially horizontal non-usage position. The backrest, includes, but is not limited to at least one height-adjustable cushion portion which, in the non-usage position of the backrest, can be moved by means of a four-bar mechanism having four articulation axes from a lower armrest non-usage position into an upper first armrest position to form an armrest for the second vehicle seat. The articulation axes extend transversely to the seat direction and are inclined with respect to a horizontal transverse to the seat direction. In an alternative embodiment, the articulation axes extend in the seat direction in the non-usage position of the backrest.
