FITTING FOR A VEHICLE SEAT, AND VEHICLE SEAT
A fitting for a vehicle seat may have a first fitting part having a toothed ring and a second fitting part having a gearwheel. The gearwheel may be in meshing engagement with the toothed ring, and the first fitting part and the second fitting part may be wobblingly rotatable relative to each other about an axis. An eccentric makes it possible to drive a relative rolling contact motion between the gearwheel and the toothed ring. The eccentric may have two wedge segments and at least one driver segment arranged between the wedge segments. The at least one driver segment may have at least one lubricant reservoir filled with a lubricant. A vehicle seat having the fitting is also provided.
1 . A fitting for a vehicle seat, comprising a first fitting part having a toothed ring and a second fitting part having a gearwheel, the gearwheel being in meshing engagement with the toothed ring, and the first fitting part and the second fitting part being wobblingly rotatable relative to each other about an axis, in that an eccentric makes it possible to drive a relative rolling contact motion between the gearwheel and the toothed ring, the eccentric having two wedge segments and at least one driver segment arranged between the wedge segments, characterized in that the at least one driver segment has at least one lubricant reservoir filled with a lubricant.
2 . The fitting according to claim 1 , characterized in that the at least one lubricant reservoir at the start of a service life of the fitting is completely filled with a lubricant and during the service life of the fitting lubricant can leave the lubricant reservoir.
3 . The fitting according to claim 1 , characterized in that the at least one driver segment has a first contact surface and a second contact surface, the at least one driver segment being radially inwardly supportable and slidingly mounted on one of the two fitting parts by the first contact surface, and radially outwardly supportable and slidingly mounted on the other one of the two fitting parts by the second contact surface.
4 . The fitting according to claim 3 , characterized in that the at least one driver segment is radially inwardly supportable and slidingly mounted on a collar of the second fitting part by the first contact surface.
5 . The fitting according to claim 4 , characterized in that the first contact surface and/or the second contact surface has an opening, through which lubricant can leave the at least one lubricant reservoir.
6 . The fitting according to claim 5 , characterized in that the at least one lubricant reservoir is formed by a depression in the first contact surface and/or a depression in the second contact surface.
7 . The fitting according to claim 6 , characterized in that the depression extends in the axial direction over the entire width of the at least one driver segment.
8 . The fitting according to claim 1 , characterized in that the eccentric has exactly one driver segment, the driver segment having the at least one lubricant reservoir.
9 . The fitting according to claim 1 , characterized in that the eccentric has two circumferentially spaced-apart driver segments, each of the two driver segments having exactly one lubricant reservoir.
10 . A vehicle seat comprising a seat part, a backrest and at least one fitting according to claim 1 , the backrest being inclination-adjustably connected to the seat part by the at least one fitting.
