Abstract
To improve comfort, a motor vehicle seat has at least one cushion body, at least one cover concealing the cushion body at least in part, and at least one tensioner, which is operatively connected to the cover by a first end and is designed to adjust the cover tension. The tensioner is fixed by a second end to a clamping device. The clamping device is designed to modify and fix the distance of the tensioner from the first end thereof to the second end thereof and the clamping device is designed to be operated after completion of the motor vehicle seat.
Claims14
A motor vehicle seat, comprising:
- at least one cushion body;
- at least one cover at least partially concealing the cushion body;
- at least one tensioner, which is operatively connected by a first end to the cover and is designed to adjust a cover tension, wherein
- the tensioner is fastened by a second end to a clamping device,
- the clamping device is designed to change and to fix a distance of the tensioner from its first end to its second end,
- the clamping device is designed to be operated after completion of the motor vehicle seat;
- and
- the clamping device comprises:
- a clamping roller which is mounted rotatably about an axis of rotation and on which the tensioner is formed in a manner such that the tensioner can be partially wound up,
- a drive which is designed to drive the clamping roller, and
- a latch which is designed to block or release the clamping roller in a desired position by pivoting.
A motor vehicle seat comprising
- at least one cushion body,
- at least one cover at least partially concealing the cushion body;
- at least one tensioner, which is operatively connected by a first end to the cover and is designed to adjust a cover tension, wherein
- the tensioner is fastened by a second end to a clamping device,
- the clamping device is designed to change and to fix a distance of the tensioner from its first end to its second end, and
- the clamping device is designed to be operated after completion of the motor vehicle seat;
- and
- at least one latch which is designed such that the latch can be received in a corresponding rack in a force-fitting, form-fitting and/or frictionally blocking manner.
A method for adjusting a cover tension of a motor vehicle seat located in a motor vehicle, the motor vehicle seat comprising at least one cushion body, at least one cover at least partially concealing the cushion body, at least one tensioner, which is operatively connected by a first end to the cover and is designed to adjust a cover tension, wherein the tensioner is fastened by a second end to a clamping device, the clamping device is designed to change and to fix a distance of the tensioner from its first end to its second end, and the clamping device is designed to be operated after completion of the motor vehicle seat, wherein the method comprises:
- defining a desired value representing a desired cover tension of the cover;
- measuring a cover tension currently present at a point in time;
- comparing the currently present cover tension with the desired value;
- when the measured cover tension is smaller than the desired value, reducing the distance of the tensioner from its first end to its second end;
- and
- when the measured cover tension is greater than the desired value, increasing the distance of the tensioner from its first end to its second end.
