Abstract

A vehicle seat, particularly a motor vehicle seat, has a seat cushion and a backrest, and a seat mechanism connecting the seat cushion and/or the backrest to at least one seat rail pair. The seat rail pair has two seat rails that can be displaced relatively to one another and which can be locked together by a rail locking mechanism. The vehicle seat can be shifted by the seat mechanism from a use position to a non-use position. A coupler couples the seat mechanism and the seat locking mechanism together in such a way that a least one seat rail pair is locked in the use position and the non-use position of the vehicle seat and is unlocked in an intermediate position of the vehicle seat located between the use position and the non-use position.

First claim

The invention claimed is:

1. A vehicle seat, comprising:
a seat cushion
a backrest;
a seat kinematic system connecting the seat cushion and/or the backrest to at least one seat rail pair,
wherein the at least one seat rail pair has two seat rails which are displaceable relative to one another and which are able to be locked together by a rail locking mechanism, and
wherein the vehicle seat is able to be transferred by the seat kinematic system from a use position into a non-use position,
wherein a coupler couples together the seat kinematic system and the rail locking mechanism such that the at least one seat rail pair is locked in the use position and in the non-use position of the vehicle seat and is unlocked in an intermediate position of the vehicle seat between the use position and the non-use position,
wherein the seat kinematic system comprises a front foot fastened to the second seat rail of the at least one seat rail pair, a front rocker connecting the front foot and the seat cushion, as well as a rear foot which is able to be releasably fastened to the second seat rail and two package rockers which pivotably articulate the rear foot to the front foot.

2. The vehicle seat as claimed in claim 1 , wherein the vehicle seat comprises two seat rail pairs arranged parallel to one another and a rail unlocking bar which is operatively connected to the rail locking mechanisms of the two seat rail pairs such that a rotation of the rail unlocking bar actuates the rail locking mechanisms of the two seat rail pairs.

3. The vehicle seat as claimed in claim 2 , wherein the rail unlocking bar extends perpendicular to the two seat rail pairs.

4. The vehicle seat as claimed in claim 2 , wherein at least one lever is fastened to the rail unlocking bar, said lever protruding in the radial direction from the rail unlocking bar and having a lever end for cooperating with the coupler.

5. The vehicle seat as claimed in claim 1 , wherein the backrest is fastened to the rear foot by a fitting.

6. The vehicle seat as claimed in claim 1 , wherein a locking pin is provided on the second seat rail for the rear foot, a lock fastened to the rear foot being able to be locked to said locking pin.

7. The vehicle seat as claimed in claim 1 , wherein the coupler has a control contour.

8. The vehicle seat as claimed in claim 7 , wherein the coupler is rotatably attached to a lever end of the rail unlocking bar and the control contour is operatively connected to a component of the seat kinematic system.

9. The vehicle seat as claimed in claim 7 , wherein the control contour is operatively connected by a control element which is movably guided inside the control contour to one of two package rockers, wherein the control element is a pin.

10. The vehicle seat as claimed in claim 1 , wherein the coupler includes a first coupler and a second coupler, wherein the first coupler is provided for the transfer of the vehicle seat from the use position into the non-use position and the second coupler is provided for the transfer from the non-use position into the use position.

11. The vehicle seat as claimed in claim 10 , wherein each of the first coupler and the second coupler is only effective in each case in one of two transfer directions.

12. A vehicle seat, comprising:
a seat cushion
a backrest;
a seat kinematic system connecting the seat cushion and/or the backrest to at least one seat rail pair,
wherein the at least one seat rail pair has two seat rails which are displaceable relative to one another and which are able to be locked together by a rail locking mechanism, and
wherein the vehicle seat is able to be transferred by the seat kinematic system from a use position into a non-use position,
wherein a coupler couples together the seat kinematic system and the rail locking mechanism such that the at least one seat rail pair is locked in the use position and in the non-use position of the vehicle seat and is unlocked in an intermediate position of the vehicle seat between the use position and the non-use position,
wherein the coupler has a control contour,
wherein the coupler is rotatably attached to a lever end of the rail unlocking bar and the control contour is operatively connected to a component of the seat kinematic system,
wherein the control contour is operatively connected by a control element which is movably guided inside the control contour to one of two package rockers, wherein the control element is a pin.

13. The vehicle seat as claimed in claim 12 , wherein the control contour comprises a slot-shaped first control portion, a slot-shaped second control portion and a catch contour positioned between the first control portion and the second control portion.

14. The vehicle seat as claimed in claim 13 , wherein when the vehicle seat is transferred from the use position into the non-use position or when transferred from the non-use position into the use position in a first phase of a movement sequence the control element is moved in the first control portion until it comes to bear against the catch contour and in a second phase of the movement sequence the control element entrains the catch contour and thus the coupler.

15. The vehicle seat as claimed in claim 14 , wherein at an end of the second phase of the movement sequence the coupler pivots against a stop and, as a result, in a further movement sequence the control element leaves the catch contour and enters the second control portion, wherein the coupler pivots back about the control element in the direction of its initial position.
