  • Patent number: 10493869
    Abstract: A backrest adjuster (4) is provided for a seat. The seat includes a backrest (1) that can be adjusted relative to a seat part (2) by a fitting (5) and which is arranged in a longitudinally displaceable manner. When the backrest (1) is displaced from a seating position (P1) to an entry position (P2), a gear unit (9) actuates a tension element (7) that unlatches a rail adjuster (10.1) and latches same when the backrest (1) is displaced in the opposite position. A vehicle seat is provided that includes such a backrest adjuster (4).

  • Patent number: 10421374
    Abstract: The invention relates to a forward pivot mechanism for positioning a seat back of a vehicle seat into at least one forward position and for positioning the seat back beyond the forward position into at least one further forward position, comprising a comfort lock for positioning and locking the seat back into a least one seated position, and comprising an easy entry latch for positioning the seat back into the at least one forward position, wherein a pivot range of the seat back into one of the forward positions can be limited by means of the easy entry latch, wherein the easy-entry latch is designed in such a way that it forms a forward limit stop during the shifting of the seat back from one of the seated positions into one of the forward positions.

  • Patent number: 10150393
    Abstract: A fitting (2) with a pivoting-forwards mechanism, positioning a backrest (1.1) of a vehicle seat (1) into a forward position, a comfort lock, positioning the backrest into a comfort region seat position (A to C), and an expanded comfort function, positioning the backrest beyond the front position into a loading platform position (E). The fitting includes a fitting part (2.1, 2.2) and a driver (4). A pivoting range of the backrest is limited in the forward position by an easy-entry latch (5) engaging in the fitting part (2.1). The easy-entry latch, when the backrest is adjusted between the seat positions in the comfort region, bears against a stop (7) mounted on the backrest and, in the forward position, is prevented by the stop from pivoting further forwards, and, when the backrest is set upright from the forward position into one of the seat positions, pivots controlled by the stop.

  • Patent number: 9758061
    Abstract: A longitudinally adjustable vehicle seat (1) includes a lower rail (5) and a longitudinally displaceably guided upper rail. A lower rail mounted end stop (40, 40b) delimits a comfort adjustment region interacting with an upper rail mounted stop element (36). The upper stop element (36) can be displaced beyond the comfort adjustment region into an easy entry region and is part of a stop module (30) that is pivotable about a pivot axis (S). The stop module (30) includes a deflector element (34) that moves upwards, when the stop element (36) has not been shifted away, in the vertical direction upon contact with a screw head (22) that is located in the cavity between the upper rail (3) and the lower rail (5). The upper stop element (36) form-fittingly engages with the end stop (40, 40b) when the end stop (40, 40b) is reached.
