Motor vehicle seat
First Claim
1. A motor vehicle seat comprising:
- a seat frame;
a swivel mounted backrest of the seat frame, which on one side is adjustable by swiveling in an area of use between different useful positions and on another side in a released state is foldable forwards by swiveling the backrest in a direction of the seat face of the seat frame;
a seat longitudinal guide that sets the seat longitudinal position;
a fixing device that locks a previously set seat longitudinal position;
a coupling mechanism through which the backrest is coupled to the fixing device so that the fixing device is released when folding the backrest forwards, wherein the coupling mechanism comprises a traction device which on swiveling the backrest transfers forces to an output side of the coupling mechanism so that the coupling mechanism acts on the fixing device, and which traction device is fixed on a holder which holder is mounted to pivot about an axis of the backrest;
a tumbler fitment of the backrest which during swiveling of the backrest tumbles about a tumbler axis and to which is coupled an input side of the coupling mechanism; and
a compensating device provided so that when the backrest is swiveled at least over a portion of the area of use, prevents release of the fixing device, and wherein the holder is not entrained by the tumbler fitment when the backrest is pivoted within the portion of the area of use.

Abstract
A motor vehicle seat having a seat frame; a pivotally mounted seat back of the seat frame that, on the one hand, can be displaced within an area of use between two different positions of use and, on the other hand, can be tilted forward toward the seat surface of the seat frame by being pivoted; a seat longitudinal guide for adjusting the longitudinal position of the seat; a fixing device for locking a previously adjusted longitudinal position of the seat, and; a coupling mechanism via which the back seat back is coupled to the fixing device whereby enabling the fixing device to be released when tilting the seat back forward toward the seat surface. Compensating features are provided for preventing the fixing device from releasing when the seat back pivots at least over a portion of the area of use.

11. A motor vehicle seat with a seat frame comprising:
-
a swivel mounted backrest of the seat frame, which on one side is adjustable by swiveling in an area of use between different useful positions and on another side is foldable forwards in a released state by swiveling the backrest towards a seat face of the seat frame; a seat longitudinal guide that sets the seat longitudinal position; a fixing device that locks a previously set seat longitudinal position; a coupling mechanism through which the backrest is coupled to the fixing device so that the fixing device is released when folding the backrest forwards; a tumbler fitment of the backrest which when swiveling the backrest tumbles about a tumbler axis and to which an input side of the coupling mechanism is coupled; and a compensating device provided which when folding the backrest forwards beyond the position in which the release of the fixing device is terminated, prevents interaction of a lever and a release lever of the coupling mechanism so that an additional action on the fixing device is prevented. - View Dependent Claims (12, 13, 14, 15)
