Abstract

Disclosed is an adjustment fitting for a motor vehicle component, especially a vehicle seat. Said adjustment fitting comprises a first part and a second part which is rotatable relative to the first part about a rotational shaft by means of a gear unit. The gear unit encompasses a first gear on the first part of the fitting and a second gear on the second part of the fitting, the second gear being disposed eccentric to the first gear. Two wedge segments are provided for securing the eccentric arrangement of the first gear relative to the second gear. The inventive adjustment fitting is characterized in that the wedge segments have an inner radius and an outer radius while the adjustment fitting further comprises a decelerating element which is fitted with an extension that starts at the rotational shaft, runs in an axial direction, and corresponds approximately to the outer radius of the wedge segments.

Dependent claims

An adjustment fitting for a vehicle seat, comprising:

a rotational shaft;
a first fitting part;
a second fitting part;
a gear unit configured to make the second fitting part rotationally adjustable about the rotational shaft relative the to first fitting part, the gear unit comprising:
a first gear on the first fitting part,
a second gear on the second fitting part arranged eccentrically to the first gear, and two wedge segments being provided for ensuring the eccentric arrangement of the first gear relative to the second gear, wherein the wedge segments have an internal radius and an external radius;
and
a braking element configured to be adjusted into a locked position and into a position of release, wherein the braking element in the radial direction starting from the rotational shaft comprises an extension approximately corresponding to the external radius of the wedge segments;
wherein the braking element further comprises a first locking element, the first locking element being provided in the locked position to engage radially to the rotational shaft in a second locking element of the first fitting part, the second locking element in the radial direction starting from the rotational shaft having a smaller extension than the second gear and than the first gear.
