  • Publication number: 20170240068
    Abstract: A vehicle seat (1), in particular a motor vehicle seat, includes a seat part (3), a backrest (5) and a four-bar-linkage arrangement (10), having a coupler (20), for the at least indirect coupling of the seat part (3) to a vehicle floor (S). The vehicle seat (1) is transferrable from a use position suitable for transporting an individual either into a first non-use position or into a second non-use position. The seat part (3) has a seat-part frame (30), which is pivotable relative to the coupler (20), and a locking device (52), which blocks a pivoting of the seat-part frame (30) relative to the coupler (20) in a first actuating state of the locking means (52). The locking device (52) permits a pivoting of the seat-part frame (30) relative to the coupler (20) in a second actuating state of the locking device (52).

  • Patent number: 8109573
    Abstract: A vehicle seat, in particular motor vehicle seat, comprises a backrest part and a seat part. The seat part has a fitting for adjusting the inclination of the backrest part in relation to the seat part. The fitting has a first fitting part which is firmly connected to the backrest part, and a second fitting part which is firmly connected to the seat part. The fitting parts are connected to one another and configured to be adjusted smoothly angularly by an adjusting mechanism. The first fitting part is able to be locked in relation to the adjusting mechanism by a latching apparatus, and is able to be pivoted about a rotational axis in relation to the adjusting mechanism after the latching apparatus is released. The adjusting mechanism comprises a toothed member, such as an internally toothed mechanism latching plate and/or an internally toothed mechanism plate. The first fitting part is mounted in a plane extending generally perpendicular to the rotational axis of the toothed member.
