Adjustable thigh support for a vehicle seat
A vehicle seat comprises a seat surface and a thigh support. The thigh support is adjustable and/or movable by use of a first adjustment device in or opposed to a first adjustment direction, which preferably runs substantially parallel to the seat surface, from an extended position into a retracted position. Furthermore, the thigh support is deflectable substantially vertically to the seat surface and/or to the underlying surface by use of a force which can be exerted by a vehicle occupant and is downwardly directed in the direction of a vehicle floor, wherein the thigh support has at least one second adjustment device for setting and/or defining a movement resistance with which the thigh support opposes the downwardly directed force.
1. A vehicle seat for a motor vehicle, comprising:
a seat surface; and
a thigh support being adjustable and/or movable by use of a first adjustment device in or opposed to a first adjustment direction, substantially parallel to the seat surface, from an extended position into a retracted position and being deflectable substantially vertical to the seat surface and/or to a vehicle floor by use of a force which can be exerted by a vehicle occupant and is directed downward in the direction of the vehicle floor, wherein the thigh support has a second adjustment device for setting and/or determining a movement resistance with which the thigh support opposes the downwardly directed force, and wherein the first adjustment device and the second adjustment device are operable and/or activatable in an interacting manner such that the position of the support relative to the thigh support does not change during the adjusting and/or moving of the position of the thigh support.
2. The vehicle seat as claimed in claim 1 , wherein the second adjustment device has at least one support, the position of which relative to the seat surface and/or to the thigh support sets or determines the movement resistance which opposes the downwardly directed force.
3. The vehicle seat as claimed in claim 1 , wherein the support is designed for displacement in or opposed to a second adjustment direction which runs substantially parallel to the seat surface.
4. The vehicle seat as claimed in claim 3 further comprising a common guide device which defines and/or determines the first adjustment direction and the second adjustment direction along which the thigh support and/or the support for setting and/or determining the movement resistance is displaceable.
5. The vehicle seat as claimed in claim 1 , wherein the first adjustment device and the second adjustment device are operable and/or activatable independently of each other.
6. The vehicle seat as claimed in claim 1 , wherein the first adjustment device and/or the second adjustment device are formed with at least one gearwheel/rack apparatus.
7. The vehicle seat as claimed in claim 6 , wherein the second adjustment device has a thigh support rack, which is fixedly connected to the thigh support, and a support rack, which is fixedly connected to the support, and the thigh support rack and support rack are in meshing engagement with a spur gearwheel.
8. The vehicle seat as claimed in claim 1 further comprising at least one device for electrical operability and/or activatability of the first adjustment device and/or of the second adjustment device.
9. A vehicle seat, comprising:
a seat surface;
a thigh support;
a first adjustment device for moving the thigh support in a first adjustment direction, substantially parallel to the seat surface between extended and retracted positions and being deflectable substantially vertical to the seat surface by use of a downward force exerted by a vehicle occupant;
a second adjustment device for setting a movement resistance with which the thigh support opposes the downward force; and
at least one device for electrical operability and/or activatability of the first adjustment device and/or of the second adjustment device.
10. The vehicle seat as claimed in claim 9 , wherein the second adjustment device has at least one support, the position of which relative to the seat surface and/or to the thigh support sets or determines the movement resistance which opposes the downwardly directed force.
11. The vehicle seat as claimed in claim 9 , wherein the support is designed for displacement in or opposed to a second adjustment direction which runs substantially parallel to the seat surface.
12. The vehicle seat as claimed in claim 11 further comprising a common guide device which defines and/or determines the first adjustment direction and the second adjustment direction along which the thigh support and/or the support for setting and/or determining the movement resistance is displaceable.
13. The vehicle seat as claimed in claim 9 , wherein the first adjustment device and the second adjustment device are operable and/or activatable in an interacting manner such that the position of the support relatively to the thigh support does not change during the adjusting and/or moving of the position of the thigh support.
14. The vehicle seat as claimed in claim 9 , wherein the first adjustment device and the second adjustment device are operable and/or activatable independently of each other.
15. The vehicle seat as claimed in claim 9 , wherein the first adjustment device and/or the second adjustment device are formed with at least one gearwheel/rack apparatus.
16. The vehicle seat as claimed in claim 15 , wherein the second adjustment device has a thigh support rack, which is fixedly connected to the thigh support, and a support rack, which is fixedly connected to the support, and the thigh support rack and support rack are in meshing engagement with a spur gearwheel.
17. A vehicle seat for a motor vehicle, comprising:
a seat surface; and
a thigh support being adjustable and/or movable by use of a first adjustment device in or opposed to a first adjustment direction, substantially parallel to the seat surface, from an extended position into a retracted position and being deflectable substantially vertical to the seat surface and/or to a vehicle floor by use of a force which can be exerted by a vehicle occupant and is directed downward in the direction of the vehicle floor, wherein the thigh support has a second adjustment device for setting and/or determining a movement resistance with which the thigh support opposes the downwardly directed force, wherein the first adjustment device and/or the second adjustment device are formed with at least one gearwheel/rack apparatus, and wherein the second adjustment device has a thigh support rack, which is fixedly connected to the thigh support, and a support rack, which is fixedly connected to the support, and the thigh support rack and support rack are in meshing engagement with a spur gearwheel.
