Abstract
In a fitting (5) for a vehicle seat, in particular for a motor vehicle seat, having two by themselves fully functional, adjacent single fittings (11, 20) defining two parallel axes (A, B), the single fittings (11, 20) are substantially axially aligned with respect to each other along the common first axis (A).
Claims20
A compound fitting for a vehicle seat, wherein the compound fitting is adjustable about a first axis, and the compound fitting comprises:
- a fully functional geared fitting for adjusting the compound fitting about the first axis, wherein the geared fitting has a second axis that is parallel to the first axis, and the geared fitting is an eccentric planetary gear system that includes
- first and second fitting parts mounted so that there can be relative rotation between the first and second fitting parts, wherein one of the first and second fitting parts comprises a gear wheel and the other of the first and second fitting parts comprises a gear rim, and
- an eccentric including a rotatably mounted driver and wedge segments configured so that the relative rotation between the first and second fitting parts of the geared fitting occurs in response to rotation of the driver;
- a fully functional detent fitting for adjusting the compound fitting about the first axis, wherein
- the detent fitting includes locking elements, a first fitting part and a second fitting part,
- the first and second fitting parts of the detent fitting are mounted so that there can be relative rotation between the first and second fitting parts of the detent fitting,
- one of the first and second fitting parts of the detent fitting comprises guides for guiding the locking elements into radially outer positions in which the locking elements cooperate with the other of the first and second fitting parts of the detent fitting to lock the detent fitting and thereby restrict relative rotation between the first and second fitting parts of the detent fitting;
- and
- a connection between the second fitting part of the geared fitting and the second fitting part of the detent fitting for restricting relative rotation between the second fitting part of the geared fitting and the second fitting part of the detent fitting, wherein the geared fitting and the detent fitting are arranged so that
- the geared fitting and the detent fitting are substantially axially aligned with respect to one another along the first axis,
- the second fitting part of the geared fitting is positioned between the first fitting part of the geared fitting and the second fitting part of the detent fitting, and
- the second fitting part of the detent fitting is positioned between the first fitting part of the detent fitting and the second fitting part of the geared fitting.

A compound fitting for a vehicle seat, wherein the compound fitting is adjustable about a first axis, and the compound fitting comprises:
- a geared fitting for adjusting the compound fitting about the first axis, wherein the geared fitting has a second axis that is parallel to the first axis, and the geared fitting includes a first fitting part and a second fitting part that are mounted so that there can be relative rotation between the first fitting part and the second fitting part;
- and
- a detent fitting for adjusting the compound fitting about the first axis, wherein
- the geared fitting and the detent fitting are mounted so that the geared fitting and the detent fitting are substantially axially aligned with respect to one another along the first axis,
- the detent fitting comprises a first fitting part and a second fitting part that are mounted so that there can be relative rotation between the first fitting part of the detent fitting and the second fitting part of the detent fitting,
- a control device controls locking of the detent fitting as a function of angular positions of elements with respect to one another, the elements are selected from the group consisting of the first fitting part of the geared fitting, the second fitting part of the geared fitting, the first fitting part of the detent fitting and the second fitting part of the detent fitting,
- the control device comprises rings, the rings are for cooperating by way of control cams with locking elements of the detent fitting, each of the locking elements of the detent fitting comprises a lug, and the control cams are for cooperating with the lugs of the locking elements of the detent fitting,
- the control device comprises compensating means for compensating for wobble motion of the geared fitting, the compensating means holds a first ring of the rings at a constant angular position relative to the first fitting part of the geared fitting, and
- a second ring of the rings remains at a constant angular position relative to the second fitting part of the geared fitting.
