Abstract

A rear vehicle seat having a seat part and a backrest is provided. The vehicle seat has a control device in connection with an adjusting device which have the purpose of implementing that, during a folding of the rear seat backrest, the seat part is displaced forward in the driving direction and lowered, and the backrest is then part of a loading surface which is constructed at the same level as the remaining loading surface of the vehicle.

Claims

1. Vehicle seat for a motor vehicle including a seat part and a swivellable seat backrest, the seat backrest being adjustable from an upright seat position into a deposited depositing position on a top side of the seat part, wherein at least one control device is arranged between the backrest and the seat part, which control device comprises a first control lever which is connected with the backrest and is hinged to a second control lever which engages with the seat part by way of an adjusting device, the second control lever has two mutually fixed lever arms and is held in a stationary pivot bearing and, at one of the second control lever'"'"'s ends, is operatively connected with a sliding block of the adjusting device and, at the second control lever'"'"'s other end, is operatively connected by a hinge joint with the first control lever and, on one hand, the seat part is adjustably moveable on a vehicle driving direction by rollers or sliding blocks arranged in stationary guide rails of a vehicle body and, on the other hand, is lowerable and raisable with respect to the vehicle body by way of swiveling levers of a lowering device.

2. Vehicle seat according to claim 1, wherein the seat part has a guide link or slotted link as an adjusting device on an underside thereof, in which guide link or slotted link the sliding block of the second control lever of the adjusting device is arranged in a manner displaceable in a direction such that, in the depositing position, the seat part takes up a pushed-forward position.

3. Vehicle seat according to claim 2, wherein the first control lever is connected with the seat backrest at a distance below a swiveling axis such that the first control lever carries out a pulling movement in a direction against a vehicle longitudinal direction, and the sliding block on the second control lever carries out a pressing movement in a vehicle driving direction.

4. Vehicle seat according to claim 2, wherein, on one hand, the seat part is adjustably moveable in a vehicle driving direction by rollers or sliding blocks arranged in stationary guide rails of a vehicle body and, on the other hand, is lowerable and raisable with respect to the vehicle body by way of swiveling levers of a lowering device.

5. Vehicle seat according to claim 1, wherein the first control lever is connected with the seat backrest at a distance below a swiveling axis such that the first control lever carries out a pulling movement in a direction against a vehicle forward direction, and the sliding block on the second control lever carries out a pressing movement in the vehicle forward direction.

6. Vehicle seat according to claim 5, wherein, on one hand, the seat part is adjustably moveable in a vehicle driving direction by rollers or sliding blocks arranged in stationary guide rails of the vehicle body and, on the other hand, is lowerable and raisable with respect to the vehicle body by way of swiveling levers of a lowering device.

7. Vehicle seat for a motor vehicle including a seat part and a swivellable seat backrest, the seat backrest being adjustable from an upright seat position into a deposited depositing position on a top side of the seat part, wherein at least one control device is arranged between the backrest and the seat part, which control device comprises a first control lever which is connected with the backrest and is hinged to a second control lever which engages with the seat part by way of an adjusting device, wherein, on one hand, the seat part is adjustably moveable in a vehicle longitudinal direction by way of rollers or sliding blocks arranged in stationary guide rails of a vehicle body and, on the other hand, is lowerable and raisable with respect to the vehicle body by way of swiveling levers of a lowering device, and the swiveling levers are mutually connected in a spaced manner by way of a crossbar and, via one end thereof, are adjustably movable about a swiveling axis linked to a seat underframe, and opposite ends of the swiveling levers are held at the seat part.

8. A vehicle assembly, comprising a rear seat including a seat part and a seat backrest, said seat backrest being adjustably movable between an upright seating position and a stowage position on a top side of the seat part, a stowage compartment having a stowage floor surface extending to a rear side of the seat backrest when in its seating position, and a control device arranged between the seat part and seat backrest to control movements between the seating position and the stowage position, said control device comprising a first control lever connected with the backrest and hinged to a second control lever which engages with the seat part by way of an adjusting device, wherein the second control lever has two mutually fixed lever arms and is held in a stationary pivot bearing and, at one of the second control lever'"'"'s ends, has a sliding block of the adjusting device and, at the second control lever'"'"'s other end, has a hinge joint with the first control lever, the seat part has a guide link or slotted link as an adjusting device on the underside, in which guide link or slotted link the sliding block of the second control lever of the adjusting device is arranged in a manner displaceable in a direction such that, in the stowage position, the seat part takes up a pushed-forward position, the first control lever is connected with the seat backrest at a distance below a swiveling axis such that the first control lever carries out a pulling movement in a direction against a vehicle forward direction, and the sliding block on the connected second control lever carries out a pressing movement in a vehicle forward direction, and on the one hand, the seat part is adjustably moveable in a vehicle driving direction by means of rollers or sliding blocks arranged in stationary guide rails of the vehicle body and, on the other hand, is lowerable and raisable with respect to the vehicle body by way of swiveling levers of a lowering device.
