Mechanical seat position detection

1. A seat position detection apparatus for a vehicle seat which is guided using a seat rail in a floor rail of the vehicle, the seat position detection apparatus comprising:

a locking unit to longitudinally set the seat rail and the floor rail relative to one another; and

a memory device including an uncoupling unit, a position detection unit having a position detection pin, a spring, and a position determination unit having a memory block with wheel gearing and a memory wheel to engage a toothed strip of the floor rail via the wheel gearing, the position determination unit to define a memory position of the vehicle seat via release of the engagement between the memory wheel and the toothed strip, the memory block including a control cam arranged on a side face of the memory wheel, the control cam having an indentation to be engaged by the position detection pin in a pretensioned manner by the spring over a first end region and thereby fix the memory position.

2. The seat position detection apparatus of claim 1 , wherein the position detection pin is connected to an actuating element of the uncoupling unit via a second end region.

3. The seat position detection apparatus of claim 2 , wherein the uncoupling unit comprises a catch rotatably mounted via a shaft.

4. The seat position detection apparatus of claim 3 , wherein the catch has an engagement cam configured to permit engagement of the catch and a recess in a shaft connected to the locking unit in a detachable manner.

5. The seat position detection apparatus of claim 2 , wherein the position detection pin is configured for detachable connection to the catch via the actuating element.

6. The seat position detection apparatus of claim 5 , wherein the catch is to be disengaged from the shaft when the position detection pin engages the indentation and is connected to the catch.

7. A seat position detection apparatus for a vehicle seat which is guided using a seat rail in a floor rail of the vehicle, the seat position detection apparatus comprising:

a memory device including:

a position detection unit including a position detection pin; and

a position determination unit including wheel gearing and a memory wheel to engage a toothed strip of the floor rail via the wheel gearing, the position determination unit to define a memory position of the vehicle seat via release of the engagement between the memory wheel and the toothed strip, the memory block including a control cam having an indentation to be engaged by the position detection pin in a pretensioned manner and thereby fix the memory position.

8. The seat position detection apparatus of claim 7 , wherein the uncoupling unit comprises a catch rotatably mounted via a shaft.

9. The seat position detection apparatus of claim 8 , wherein the catch has an engagement cam configured to permit engagement of the catch and a recess in a shaft connected to the locking unit in a detachable manner.

10. The seat position detection apparatus of claim 9 , wherein the position detection pin is configured for detachable connection to the catch via the actuating element.

11. The seat position detection apparatus of claim 10 , wherein the catch is to be disengaged from the shaft when the position detection pin engages the indentation and is connected to the catch.

12. A vehicle seat, comprising:

a floor rail;

a seat rail in the floor rail to guide the vehicle seat; and

a seat position detection apparatus configured to detect a position of the vehicle seat, the seat position detection apparatus including:

a memory device including a position detection unit including a detection pin and a position determination unit including wheel gearing and a memory wheel to engage a toothed strip of the floor rail via the wheel gearing, the position determination unit to define a memory position of the vehicle seat via release of the engagement between the memory wheel and the toothed strip, the memory block including a control cam having an indentation to be engaged by the detection pin in a pretensioned manner and thereby fix the memory position.

13. The vehicle seat of claim 12 , wherein the uncoupling unit comprises a catch rotatably mounted via a shaft.

14. The vehicle seat of claim 13 , wherein the catch has an engagement cam configured to permit engagement of the catch and a recess in a shaft connected to the locking unit in a detachable manner.

15. The vehicle seat of claim 14 , wherein the position detection pin is configured for detachable connection to the catch via the actuating element.

16. The vehicle seat of claim 15 , wherein the catch is to be disengaged from the shaft when the position detection pin engages the indentation and is connected to the catch.
