Abstract

An assembly includes a base and a seatbelt anchor. The seatbelt anchor has a first end defining a circular hole pivotally supported by the base and a second end fixed in position relative to the first end. The assembly includes a buckle fixed in position relative to the second end. The assembly includes a pyrotechnic actuator secured to the base. The assembly includes a connector extending from the pyrotechnic actuator to the seatbelt anchor.

First claim

What is claimed is:

1. An assembly comprising:
a seat back;
a seat bottom extending form the seat back in a seat-forward direction;
a base;
a seatbelt anchor having a first end defining a circular hole pivotally supported by the base and a second end fixed in position relative to the first end, the seatbelt anchor pivotable from a first position to a second position that is in the seat-forward direction relative to the first position;
a buckle fixed in position relative to the second end;
a pyrotechnic actuator secured to the base; and
a connector extending from the pyrotechnic actuator to the seatbelt anchor; and
wherein actuation of the pyrotechnic actuator moves the seatbelt anchor from the first position to the second position.

2. The assembly of claim 1 , wherein the connector is a cable securing the pyrotechnic actuator to the base.

3. The assembly of claim 1 , wherein the pyrotechnic actuator is designed to move the seatbelt anchor from the first position to the second position.

4. The assembly of claim 1 , wherein the pyrotechnic actuator is in the seat-forward direction relative to the seatbelt anchor.

5. The assembly of claim 1 , wherein the base is a vehicle floor.

6. The assembly of claim 1 , wherein the base is fixed to the seat bottom.

7. The assembly of claim 6 , wherein the seat bottom pivotally supports the seatbelt anchor at the circular hole.

8. The assembly of claim 6 , wherein the pyrotechnic actuator is secured to the seat bottom.

9. The assembly of claim 1 , wherein the seatbelt anchor is metal.

10. The assembly of claim 1 , further comprising a processor and a memory storing instructions executable by the processor to actuate the pyrotechnic actuator upon detecting a vehicle impact.

11. The assembly of claim 1 , further comprising a processor and a memory storing instructions executable by the processor to actuate the pyrotechnic actuator only upon detecting an oblique vehicle impact.

12. The assembly of claim 11 , wherein the oblique vehicle impact includes a vehicle impact offset at 15 degrees from a vehicle forward-direction.

13. The assembly of claim 1 , further comprising a processor and a memory storing instructions executable by the processor to actuate the pyrotechnic actuator upon detecting a vehicle impact offset at 15 degrees from a vehicle forward-direction.

14. The assembly of claim 1 , wherein the connector is fixed to the seatbelt anchor between the first end and the second end.

15. The assembly of claim 1 , wherein the seatbelt anchor is monolithic.
