Abstract

A vehicle seat, such as for a motor vehicle seat, adapted to be transferable from at least one use position, which is suitable for transporting a passenger, into an easy entry position as a non-use position, and back, may have a seat cushion, a backrest, and a seat frame. The seat cushion and the backrest may be coupled to the seat frame, a base and a kinematics for the articulated connection of the seat frame to the base. The kinematics may have at least one link articulated connecting the seat frame to the base. The at least one link may be lockable by a disc shaped fitting or the at least one link may be lockable with the seat frame by a locking device.

First claim

1 - 15 . (canceled)

16 . A vehicle seat adapted to be transferable from at least one use position, which is suitable for transporting a passenger, into an easy entry position as a non-use position, and back, comprising:
a seat cushion, a backrest, a seat frame, the seat cushion and the backrest being coupled to the seat frame, a base and a kinematics for the articulated connection of the seat frame to the base, wherein the kinematics comprises at least one link articulated connecting the seat frame to the base, wherein the at least one link is lockable by a disc shaped fitting.

17 . The vehicle seat according to claim 16 , wherein the kinematics is a four bar linkage.

18 . The vehicle seat according to claim 17 , wherein the four bar linkage comprises a front link and a rear link;
the front link being connected to the base by a first swivel joint and the front link being connected to the seat frame by a second swivel joint; the rear link being connected to the base by a third swivel joint and the rear link being connected to the seat frame by a fourth swivel joint.

19 . The vehicle seat according to claim 16 , wherein the disc shaped fitting comprises a first fitting part, a second fitting part rotatable about an axis in relation to the first fitting part, and at least a locking device for locking the rotation between the first fitting part and the second fitting part.

20 . The vehicle seat according to claim 16 , wherein the fitting comprises a first fitting part and a second fitting part, which are rotatable relative to each other and which are in geared connection with each other via a toothed ring and a gear wheel meshing with the toothed ring, and an eccentric intended for driving a relative rolling movement of the gear wheel and the toothed ring.

21 . The vehicle seat according to claim 18 , wherein the third swivel joint is formed by the disc shaped fitting.

22 . The vehicle seat according to claim 16 , wherein a cover is covering the disc shaped fitting and at least partly the base, the at least one link being pivotable relative to the cover.

23 . A vehicle seat adapted to be transferable from at least one use position, which is suitable for transporting a passenger, into an easy entry position as a non-use position, and back, comprising:
a seat cushion, a backrest, a seat frame, the seat cushion and the backrest being coupled to the seat frame, a base, and a kinematics for the articulated connection of the seat frame to the base, wherein the kinematics comprises at least one link articulated connecting the seat frame to the base, wherein the at least one link is lockable with the seat frame by a locking device.

24 . The vehicle seat according to claim 23 , wherein the kinematics is a four bar linkage.

25 . The vehicle seat according to claim 24 , wherein the four bar linkage comprises a front link and a rear link;
the front link being connected to the base by a first swivel joint and the front link being connected to the seat frame by a second swivel joint; the rear link being connected to the base by a third swivel joint and the rear link being connected to the seat frame by a fourth swivel joint.

26 . The vehicle seat according to claim 24 , wherein the locking device is designed as a rotary latch lock for receiving and locking a counter element.

27 . The vehicle seat according to claim 26 , wherein the locking device is fixedly connected to the seat frame and the counter element is fixedly connected to the at least one link.

28 . The vehicle seat according to claim 27 , wherein the counter element is designed as a bolt.

29 . The vehicle seat according to claim 28 , wherein the counter element is arranged in a U-shaped region of the at least one link.

30 . The vehicle seat according to 23 , wherein a cover is covering the locking device and at least partly the rear link, the rear link being pivotable relative to the cover.
