Abstract

A vehicle seat system includes a support surface having a first side and a second side that is opposite the first side. A first seat rail is coupled to the first side of the support surface. A second seat rail is coupled to the first side of the support surface spaced from the first seat rail. A seat member includes a first stanchion moveably supported at the first seat rail, a second stanchion moveably supported at the second seat rail, and a member arranged between the first stanchion and the second stanchion. A magnet is mounted at the second side of the support surface. A levitation controller is operatively connected to the magnet. The levitation controller is activated to drive the magnet to repel the member and raise the first stanchion and the second stanchion relative to corresponding ones of the first seat rail and the second seat rail.

First claim

What is claimed is:

1. A vehicle seat system comprising:
a support surface having a first side and a second side that is opposite the first side;
a first seat rail coupled to the first side of the support surface;
a second seat rail coupled to the first side of the support surface spaced from the first seat rail;
a seat member including a first stanchion moveably supported at the first seat rail, a second stanchion moveably supported at the second seat rail, and a member arranged between the first stanchion and the second stanchion, the member being formed from a magnetic material;
a magnet mounted at the second side of the support surface; and
a levitation controller operatively connected to the magnet, the levitation controller being selectively activated to drive the magnet to repel the member and raise the first stanchion and the second stanchion relative to corresponding ones of the first seat rail and the second seat rail.

2. The vehicle seat system according to claim 1 , wherein the magnet includes a plurality of magnets arrayed about the second side of the support surface.

3. The vehicle seat system according to claim 2 , wherein the levitation controller selectively controls one or more of the plurality of magnets to repel the member and raise the first stanchion and the second stanchion relative to the first seat rail and the second seat rail respectively.

4. The vehicle seat system according to claim 2 , wherein the levitation controller selectively controls one or more of the plurality of magnets to shift the seat member relative to the first seat rail and the second seat rail.

5. The vehicle seat system according to claim 4 , wherein the levitation controller selectively controls one or more of the plurality of magnets to establish one of a plurality of pre-determined seat positions for the seat member.

6. The vehicle seat system according to claim 5 , wherein the support surface includes a plurality of locking elements.

7. The vehicle seat system according to claim 6 , further comprising another member arranged between the first stanchion and the second stanchion, the another member supporting a locking member configured to engage one of the plurality of locking elements to secure the seat member in the one of the plurality of pre-determined seat positions.

8. The vehicle seat system according to claim 7 , wherein the locking member comprises a selectively extendable pin and the plurality of locking elements comprise a plurality of openings formed in the support surface, the selectively extendable pin passing into the one of the plurality of openings to secure the seat member in the one of the plurality of pre-determined seat positions.

9. The vehicle seat system according to claim 8 , wherein the selectively extendable pin includes a selectively deployable locking portion that selectively prevents withdrawal of the selectively extendable pin from the one of the plurality of openings.

10. The vehicle seat system according to claim 8 , further comprising a cam mechanism that selectively shifts the selectively extendable pin into the one of the plurality of openings.

11. A vehicle comprising:
a body defining a passenger compartment; and
a vehicle seat system arranged in the passenger compartment, the vehicle seat system comprising:
a support surface having a first side and a second side that is opposite the first side;
a first seat rail coupled to the first side of the support surface;
a second seat rail coupled to the first side of the support surface spaced from the first seat rail;
a seat member including a first stanchion moveably supported at the first seat rail, a second stanchion moveably supported at the second seat rail, and a member arranged between the first stanchion and the second stanchion, the member being formed from a magnetic material;
a magnet mounted at the second side of the support surface; and
a levitation controller operatively connected to the magnet, the levitation controller being selectively activated to drive the magnet to repel the member and raise the first stanchion and the second stanchion relative to corresponding ones of the first seat rail and the second seat rail.

12. The vehicle according to claim 11 , wherein the magnet includes a plurality of magnets arrayed about the second side of the support surface.

13. The vehicle according to claim 12 , wherein the levitation controller selectively controls one or more of the plurality of magnets to repel the member and raise the first stanchion and the second stanchion relative to the first seat rail and the second seat rail respectively.

14. The vehicle according to claim 12 , wherein the levitation controller selectively controls one or more of the plurality of magnets to shift the seat member relative to the first seat rail and the second seat rail.

15. The vehicle according to claim 14 , wherein the levitation controller selectively controls one or more of the plurality of magnets to establish one of a plurality of pre-determined seat positions for the seat member.

16. The vehicle according to claim 15 , wherein the support surface includes a plurality of locking elements.

17. The vehicle according to claim 16 , further comprising another member extending between the first stanchion and the second stanchion, the another member supporting a locking member configured to engage one of the plurality of locking elements to secure the seat member in the one of the plurality of pre-determined seat positions.

18. The vehicle according to claim 17 , wherein the locking member comprises a selectively extendable pin and the plurality of locking elements comprise a plurality of openings formed in the support surface, the selectively extendable pin passing into the one of the plurality of openings to secure the seat member in the one of the plurality of pre-determined seat positions.

19. The vehicle according to claim 18 , wherein the selectively extendable pin includes a selectively deployable locking portion that selectively prevents withdrawal of the selectively extendable pin from the one of the plurality of openings.

20. The vehicle according to claim 18 , further comprising a cam mechanism that selectively shifts the selectively extendable pin into the one of the plurality of openings.
