Abstract

A gearing arrangement for a spindle drive arrangement may have a gearing housing and a gearing holder. The gearing holder may have at least two receiving openings, one for each fastening screw or one for each fastening bolt for fastening to another component, in particular to a vehicle seat. The at least two receiving openings may be oriented at right-angles and/or obliquely with respect to one another. A spindle drive arrangement having such a gearing arrangement, and also to a vehicle seat having such a spindle drive arrangement is also provided.

First claim

What is claimed is:

1. A gear arrangement for a spindle drive arrangement, comprising a gear housing and a gear holder, the gear holder having at least two receiving openings receiving one fastening screw or one fastening pin for fastening to a vehicle seat, and these at least two receiving openings being oriented at a right angle and/or obliquely with respect to one another,
wherein the gear housing and the gear holder have corresponding connecting elements for connecting the gear housing to the gear holder,
wherein the connecting elements of the gear housing are configured as a pin, and the connecting elements of the gear holder are configured as a receiving pocket for receiving one of the pins,
wherein the receiving pockets having an insertion opening and a mounting opening, and the pins are configured so that, in a mounting orientation of the gear housing with respect to the gear holder, they are inserted through the respective insertion opening and into the respective mounting opening and are rotated in the mounting opening, an insertion of the respective pin through the respective insertion opening being blocked in the case of an orientation, differing from the mounting orientation, of the gear housing with respect to the gear holder, in at least one operating orientation of the gear housing.

2. The gear arrangement as claimed in claim 1 , wherein the connecting elements of the gear holder are configured as a pin, and the connecting elements of the gear housing are configured as a receiving pocket for receiving one of the pins.

3. The gear arrangement as claimed in claim 1 , wherein the respective insertion opening are a slot-shaped configuration, the respective mounting opening are a round configuration, and the respective pin are a web-shaped configuration.

4. The gear arrangement as claimed in claim 3 , wherein the respective pin is configured so that a length of its cross section is greater than a width of its cross section, a width of the cross section of the respective pin being smaller than a width of the respective insertion opening.

5. The gear arrangement as claimed in claim 4 , wherein the length of the cross section of the respective pin is greater than the width of the respective insertion opening, and the length of the cross section of the respective pin corresponds to a diameter of the respective mounting opening.

6. The gear arrangement as claimed in claim 1 , wherein the gear housing comprising a gear cover with an opening for leading through a threaded spindle.

7. The gear arrangement as claimed in claim 1 , wherein an outer side of the gear cover bears against the gear holder and slides along on the gear holder during rotational movements of the gear housing relative to the gear holder in that state of the gear housing and the gear holder, in which they are connected to one another, and in an orientation, differing from the mounting orientation, of the gear housing with respect to the gear holder.

8. The gear arrangement as claimed in claim 7 , wherein the gear holder, in at least one operating orientation of the gear housing with respect to the gear holder, is arranged laterally next to the gear housing exclusively in the axial direction of the threaded spindle.

9. The gear arrangement as claimed in claim 1 , wherein the connecting elements of the gear housing and the connecting elements of the gear holder are arranged laterally next to the threaded spindle in at least one operating orientation of the gear housing with respect to the gear holder.

10. The gear arrangement as claimed in claim 9 , wherein the connecting elements of the gear housing and the connecting elements of the gear holder are arranged laterally next to the threaded spindle in the radial direction of the threaded spindle.

11. A spindle drive arrangement, comprising a gear arrangement as claimed in claim 1 .

12. A vehicle seat, comprising a spindle drive arrangement as claimed in claim 11 .

13. The gear arrangement as claimed in claim 2 , wherein the receiving pockets have an insertion opening and a mounting opening, and the pins are configured so that, in a mounting orientation of the gear housing with respect to the gear holder, they are inserted through the respective insertion opening and into the respective mounting opening and are rotated in the mounting opening, an insertion of the respective pin through the respective insertion opening being blocked in the case of an orientation, differing from the mounting orientation, of the gear housing with respect to the gear holder, of at least one operating orientation of the gear housing.

14. A gear arrangement for a spindle drive arrangement, comprising a gear housing and a gear holder, the gear holder having at least two receiving openings for one fastening screw or one fastening pin for fastening to a vehicle seat, and these at least two receiving openings being oriented at a right angle and/or obliquely with respect to one another,
wherein the gear housing and the gear holder have corresponding connecting elements for connecting the gear housing to the gear holder,
wherein the connecting elements of the gear holder are configured as a pin, and the connecting elements of the gear housing are configured as a receiving pocket for receiving one of the pins,
wherein the receiving pockets have an insertion opening and a mounting opening, and the pins are configured so that, in a mounting orientation of the gear housing with respect to the gear holder, they are inserted through the respective insertion opening and into the respective mounting opening and are rotated in the mounting opening, an insertion of the respective pin through the respective insertion opening being blocked in the case of an orientation, differing from the mounting orientation, of the gear housing with respect to the gear holder, in at least one operating orientation of the gear housing.
