Abstract

A fitting for a vehicle seat, the fitting having a first fitting part, a second fitting part and an eccentric pivoting the first fitting part and the second fitting part eccentrically with respect to each other about an eccentricity. In the event of an overload acting on the fitting, in particular in the event of an overload torque acting about the axis of rotation, the first fitting part and the second fitting part can be supported radially against each other by at least one supporting ring segment arranged radially outside the eccentric. A motor vehicle seat may have the at least one fitting.

Claims (20)

1 . A fitting for a vehicle seat, the fitting having a first fitting part, a second fitting part and an eccentric pivoting the first fitting part and the second fitting part eccentrically with respect to each other about an eccentricity, the first fitting part having a toothed ring and the second fitting part having a gearwheel, the toothed ring and the gearwheel being in meshing engagement with each other, where, in order to drive a relative rolling contact motion of gearwheel and toothed ring, the eccentric is rotatable about an axis of rotation, wherein at least one supporting ring segment which rotates together with the eccentric is arranged radially outside the eccentric, and in the event of an overload acting on the fitting, in particular in the event of an overload torque acting about the axis of rotation, the first fitting part and the second fitting part can be supported radially against each other by the at least one supporting ring segment,

wherein the at least one supporting ring segment is connected to a driver segment of the eccentric by a connecting element,

wherein the at least one supporting ring segment is fastened to the connecting element by being clipped to the connecting element.

2 . The fitting as claimed in claim 1 , wherein the eccentric has two wedge segments and the driver segment.

3 . The fitting as claimed in claim 2 , wherein the at least one supporting ring segment is connected to the driver segment by the connecting element.

4 . The fitting as claimed in claim 2 , wherein the at least one supporting ring segment is arranged radially opposite the two wedge segments.

5 . The fitting as claimed in claim 2 , wherein the at least one supporting ring segment has at least one first supporting surface for radially supporting at least one step of the first fitting part.

6 . The fitting as claimed in claim 5 , wherein the at least one step of the first fitting part is formed circumferentially.

7 . The fitting as claimed in claim 5 , wherein the at least one supporting ring segment has at least one second supporting surface for radially supporting at least one step of the second fitting part.

8 . The fitting as claimed in claim 7 , wherein the at least one step of the second fitting part is formed circumferentially.

9 . The fitting as claimed in claim 8 , wherein at least one spring preloads the at least one supporting ring segment against the step of the second fitting part or against the step of the first fitting part.

10 . The fitting as claimed in claim 7 , wherein the second supporting surface is in direct abutting contact with the at least one step of the second fitting part.

11 . The fitting as claimed in claim 5 , wherein the first supporting surface is in direct abutting contact with the at least one step of the first fitting part.

12 . The fitting as claimed in claim 2 , wherein the at least one supporting ring segment is formed separately from the driver segment.

13 . The fitting as claimed in claim 1 , wherein two supporting ring segments are provided which are preloaded onto each other in the circumferential direction by a force storage device comprised of a compression spring and/or a tension spring, wherein the force storage device is preloaded against a stop of the driver segment.

14 . The fitting as claimed in claim 1 , wherein the connecting element has a force storage arrangement comprising at least one spring for radially preloading the connecting element.

15 . A vehicle seat for a motor vehicle having at least one fitting as claimed in claim 1 .

16 . The fitting as claimed in claim 1 , wherein the supporting ring segment extends over an angle of less than 360 degrees.

17 . The fitting as claimed in claim 1 , wherein the supporting ring segment extends over an angle of less than 180 degrees.

18 . The fitting as claimed in claim 1 , wherein the supporting ring segment extends over a same angle as the driver segment.
