Adjusting device for a vehicle seat having a self-adjusting brake
View Patent ↗An adjusting device for a vehicle component, in particular for the seat back of a vehicle seat, has a first and a second fitting part which are disposed along an axis of rotation. The relative position of the two fitting parts with respect to one another can be changed. A torque is transmitted by a drive to a gear which rolls on the second fitting part and thereby adjusts the second fitting part.
1. An adjusting device for a vehicle component, comprising:
a first fitting part and a second fitting part which are arranged along a rotational axis;
an eccentric that alters the relative position of the first and second fitting parts to one another,
wherein the eccentric is configured to transmit a torque to a gearwheel,
wherein the torque is from a drive unit,
wherein the gearwheel is rollable on the second fitting part,
wherein the eccentric has two eccentric members; and
a braking member which at least substantially prevents a self-adjustment thereof,
wherein the braking member cooperates with a locking contour which is provided on the gearwheel,
wherein the braking member has only one arm,
wherein the arm has a blocking element at an end of the arm,
wherein the blocking element is configured to lock to the locking contour.
2. The adjusting device as claimed in claim 1 , wherein the locking contour is provided in a region of an internal diameter of the gearwheel.
3. The adjusting device as claimed in claim 1 , wherein the locking contour is connected to the gearwheel by a non-positive and/or material connection.
4. The adjusting device as claimed in claim 1 , wherein the locking contour is provided integrally with the gearwheel.
5. The adjusting device as claimed in claim 1 , wherein the arm comprises a ramp which cooperates with the drive unit member.
6. The adjusting device as claimed in claim 1 , wherein an axial extent of a bearing of the gearwheel is greater than an axial extent of teeth of the gearwheel.
7. The adjusting device as claimed in claim 6 , wherein the gearwheel has a sealing surface.
8. The adjusting device as claimed in claim 7 , wherein the sealing surface is provided in a radial direction.
9. The adjusting device as claimed in claim 7 , wherein the sealing surface sealingly cooperates with a cover and/or the drive unit.
