Abstract

A system includes a vehicle roof. A track is fixed to the vehicle roof. A seatbelt retractor is engaged with the track and is movable relative to the vehicle roof along the track. The seatbelt retractor may be selectively positioned relative to the vehicle roof.

First claim

What is claimed is:

1. A system comprising:
a vehicle roof;
a track fixed to the vehicle roof;
a seatbelt retractor engaged with the track and movable relative to the vehicle roof along the track;
a seat rotatable about an axis that extends through the seat and the vehicle roof;
the seat including a seat back having an upper end and a webbing guide at the upper end; and
a seatbelt webbing extending from the retractor through the webbing guide.

2. The system of claim 1 , wherein the seatbelt webbing includes an end anchored to the seat.

3. The system of claim 1 , further comprising a vehicle floor and a seat track fixed to the vehicle floor, the seat being rotatable relative to the seat track.

4. The system of claim 3 , further comprising a solenoid fixed to one of the seat and the seat track and releasably engageable with the other of the seat and the seat track.

5. The system of claim 4 , further comprising a processor and a memory storing instructions to actuate the solenoid in response to operation of a switch.

6. The system of claim 4 , further comprising a second solenoid fixed to the seatbelt retractor and releasably engageable with the track.

7. The system of claim 6 , further comprising a processor and a memory storing instructions to simultaneously actuate the solenoid and the second solenoid in response to operation of a switch.

8. The system of claim 1 , wherein the track is continuous.

9. The system of claim 1 , further comprising a bearing between the track and the seatbelt retractor.

10. The system of claim 1 , further comprising a solenoid fixed to the seatbelt retractor and releasably engageable with the track.

11. The system of claim 10 , further comprising a processor and a memory storing instructions to actuate the solenoid in response to operation of a switch.

12. The system of claim 10 , further comprising a processor and a memory storing instructions to actuate the solenoid in response to a vehicle impact.

13. The system of claim 10 , further comprising a processor and a memory storing instructions to actuate the solenoid in response to a vehicle impact.

14. A system, comprising:
a track; and
a seatbelt retractor slideably engaged with the track;
a solenoid fixed to one of the seatbelt retractor and the track and releasably engageable with the other of the seatbelt retractor and the track.

15. The system of claim 14 , further comprising a processor and a memory storing instructions to actuate the solenoid in response to operation of a switch.

16. The system of claim 14 , wherein the track is circular.

17. A system comprising:
a vehicle roof;
a track fixed to the vehicle roof;
a seatbelt retractor engaged with the track and movable relative to the vehicle roof along the track; and
a solenoid fixed to the seatbelt retractor and releasably engageable with the track.

18. The system of claim 17 , further comprising a processor and a memory storing instructions to actuate the solenoid in response to a vehicle impact.

19. The system of claim 17 , further comprising a seatbelt webbing extending from the seatbelt retractor to the seat.

20. The system of claim 17 , wherein the track is continuous.
