Abstract

A seat position detecting device includes a stationary rail fixedly attached to a stationary part, a movable rail movable relative to the stationary rail, a case mounted to one of the stationary rail and the movable rail and housing a position detecting member for detecting a position of the one relative to the other of the stationary rail and the movable rail, and a positioning member formed with the case and extending in a direction of a detected member so as to determine a relative position between the case and the detected member. The positioning member is removable from the case after positioning the case relative to the detected member.

Claims

1. A seat position detecting device comprising:

a stationary rail fixedly attached to a stationary part;

a movable rail movable relative to the stationary rail;

a case mounted to one of the stationary rail and the movable rail and housing a position detecting means for detecting a position of the one relative to the other of the stationary rail and the movable rail; and

a positioning member formed with the case and extending in a direction of a detected member so as to determine a relative position between the case and the detected member, wherein the positioning member is removable from the case after positioning the case relative to the detected member.

2. A seat position detecting device according to claim 1, wherein the positioning member is made of a resin material.

3. A seat position detecting device according to claim 1, wherein the case and the positioning member are integrally formed.

4. A seat position detecting device according to claim 3, wherein the positioning member and the case are integrally formed with a resin material.

5. A seat position detecting device according to claim 1, wherein the position of the case relative to the one of the stationary rail and the movable rail is adjustable by means of an elongated hole and a pin.

6. A seat position detecting device according to claim 1, wherein the position of the case relative to the one of the stationary rail or the movable rail is adjustable by means of an elongated hole and a screw.

7. A seat position detecting device according to claim 1, further comprising:

the position detecting means including;

a magnetic force-voltage converting element;

a magnet arranged in parallel with the magnetic force-voltage converting element;

a yoke arranged at an opposite side of the magnetic force-voltage converting element relative to the magnet;

a connector electrically connected to the magnetic force-voltage converting element, wherein the magnetic force-voltage converting element, the magnet, the yoke, and the connector are housed in the case as a unit.

8. A seat position detecting device according to claim 7, wherein the detected member and the other of the stationary rail and the movable rail are integrally made of a magnetic material.

9. A seat position detecting device according to claim 7, wherein the detected member is a position indicating means mounted on the other of the stationary rail and the movable rail.

10. A seat position detecting device according to claim 8, wherein a magnetic flux intensity detected by the magnetic force-voltage converting element is changed by the detected member and the other integrally made of the magnetic material when the position detecting means comes close to the detected member and the other.

11. A seat position detecting device according to claim 9, wherein a magnetic flux intensity detected by the magnetic force-voltage converting means is changed by the position indicating means when the position detecting means comes closed to the position indicating means.

12. A seat position detecting device for a vehicle seat comprising:

a stationary rail fixedly attached to a vehicle floor;

a movable rail mounting the vehicle seat thereon and being movable relative to the stationary rail;

a case mounted to the movable rail and housing a position detecting means for detecting a position of the movable rail relative to the stationary rail; and

a positioning member formed with the case and extending in a direction of a detected member so as to determine a relative position between the case and the detected member, wherein the positioning member is removable from the case after positioning the case relative to the detected member.

13. A seat position detecting device according to claim 12, wherein the positioning member is made of a resin material.

14. A seat position detecting device according to claim 12, wherein the case and the positioning member are integrally formed.

15. A seat position detecting device according to claim 12, wherein the positioning member and the case are integrally formed with a resin material.

16. A seat position detecting device according to claim 12, wherein the position of the case relative to the stationary rail is adjustable by means of an elongated hole and a pin.

17. A seat position detecting device according to claim 12, wherein the position of the case relative to the stationary rail is adjustable by means of an elongated hole and a screw.

18. A seat position detecting device according to claim 12, further comprising:

the position detecting means including;

a magnetic force-voltage converting element;

a magnet arranged in parallel with the magnetic force-voltage converting element;

a yoke arranged at an opposite side of the magnetic force-voltage converting element relative to the magnet;

a connector electrically connected to the magnetic force-voltage converting element, wherein the magnetic force-voltage converting element, the magnet, the yoke, and the connector are housed in the case as a unit.

19. A seat position detecting device according to claim 18, wherein the detected member and the stationary rail are integrally made of a magnetic material.

20. A seat position detecting device according to claim 18, wherein the detected member is a position indicating means mounted on the stationary rail.

21. A seat position detecting device according to claim 19, wherein a magnetic flux intensity detected by the magnetic force-voltage converting element is changed by the detected member and the stationary rail integrally made of the magnetic material when the position detecting means comes close to the detected member and the stationary rail.

22. A seat position detecting device according to claim 20, wherein a magnetic flux intensity detected by the magnetic force-voltage converting means is changed by the position indicating means when the position detecting means comes closed to the position indicating means.

23. A seat position detecting device according to claim 22, wherein the position indicating means extends from a predetermined position on the stationary rail in a vehicle forward direction.
