Abstract

An assembly includes a seat and an armrest moveable relative to the seat. A first arm and a second arm each include a first hinge and a second hinge. The first hinges are spaced from each other and fixed relative to the seat. The second hinges are spaced from each other and fixed relative to the armrest.

First claim

What is claimed is:

1. An assembly comprising:
a seat having a seatback and a seat bottom extending from the seatback along a seat axis;
an armrest mounted to the seat, the armrest being moveable relative to the seat; and
a first arm and a second arm each including a first hinge and a second hinge, the first hinges being spaced from each other and fixed relative to the seat, the second hinges being spaced from each other and fixed relative to the armrest, the first hinge and the second hinge being rotatable about axes that are parallel to the seat axis.

2. The assembly of claim 1 , further comprising an inflatable device inflatable to an inflated position, the inflatable device being between the seat and the armrest in the inflated position.

3. The assembly of claim 2 , wherein the inflatable device is supported on the armrest.

4. The assembly of claim 1 , further comprising an inflatable device supported on one of the armrest and the seat and inflatable toward the other of the armrest and the seat.

5. The assembly of claim 4 , further comprising:
a locking device between the armrest and the seat, the locking device being movable between an engaged position locking the armrest relative to the seat and a disengaged position releasing the armrest relative to the seat;
the locking device including a releasable connection between the seat and the armrest; and
the inflatable device being operable to break the releasable connection when the inflatable device is inflated.

6. The assembly of claim 1 , wherein the first hinges are fixed to the seat bottom.

7. The assembly of claim 6 , wherein the second hinges are fixed to the armrest.

8. The assembly of claim 1 , wherein the second hinges are fixed to the armrest.

9. The assembly of claim 1 , further comprising a releasable connection between the seat and the armrest.

10. The assembly of claim 1 , further comprising a locking device between the armrest and the seat, the locking device being movable between an engaged position locking the armrest relative to the seat and a disengaged position releasing the armrest relative to the seat.

11. The assembly of claim 10 , further comprising a plate extending from the seat, the locking device engaging the plate and the armrest in the engaged position, and disengaging the plate from the armrest in the disengaged position.

12. The assembly of claim 11 , wherein plate includes a plurality of holes alternately engageable with the locking device.

13. The assembly of claim 12 , wherein the holes are spaced in an arcuate pattern.

14. The assembly of claim 10 , wherein the locking device includes a releasable connection between the seat and the armrest.

15. The assembly of claim 14 , wherein the releasable connection is frangible relative to the plate.

16. The assembly of claim 14 , wherein the releasable connection is a shear pin.

17. The assembly of claim 1 , wherein the armrest includes a support member fixed relative to the second hinges of the first and second arms and a top supported by and moveably engaged with the support member.

18. The assembly of claim 17 , wherein the top of the armrest is moveable vertically relative to the support member.

19. The assembly of claim 1 , further comprising a motor engageable with at least one of the first arm and the second arm and designed to move the first and second arms about the first and second hinges.

20. The assembly of claim 19 , further comprising a releasable connection between the motor and the at least one of the first arm and second arm, the releasable connection being frangible relative to at least one of the motor and the at least one of the first arm and the second arm.
