Abstract

A bumper for a vehicle armrest assembly includes a base that extends from a first end to a second end. The base includes a front surface. The bumper includes a stop that extends from the front surface of the base. The bumper also includes a cushion that extends from the front surface of the base. The cushion extends a greater distance from the base than the stop.

First claim

What is claimed is:

1. A bumper for a vehicle armrest assembly comprising:
a base including a front surface and a rear surface that is opposite to the front surface;
a stop that extends from the front surface of the base;
a cushion that extends from the front surface of the base a greater distance from the front surface of the base than the stop; and
a retainer that extends from a rear side of the base and is made of a material that is harder than the base.

2. The bumper for a vehicle armrest assembly of claim 1 , wherein the cushion is a first cushion, and further including a second cushion that extends from the front surface of the base, and wherein the stop is located between the first cushion and the second cushion.

3. The bumper for a vehicle armrest assembly of claim 1 , wherein the cushion includes a cushion arc that extends from the base, and wherein an internal space is defined between the cushion arc and the base.

4. The bumper for a vehicle armrest assembly of claim 3 , further including a surface texture on an external surface of the cushion arc.

5. The bumper for a vehicle armrest assembly of claim 4 , wherein the surface texture includes a raised ridge on the external surface of the cushion arc.

6. An armrest assembly comprising:
a frame;
an armrest mounted to the frame for relative rotational movement;
a latch adapted so that when the armrest is in a storage position relative to the frame, the latch retains the armrest against movement relative to the frame; and
a bumper that engages the armrest and the frame when the armrest is in the latched position relative to the frame, the bumper including a stop that limits rotation of the armrest in a first direction relative to the frame and a cushion that biases the armrest in a second direction relative to the frame.

7. The armrest assembly of claim 6 , wherein the bumper includes a cushion that is compressed when the armrest is in the latched position.

8. The armrest assembly of claim 6 , wherein the bumper includes a base that extends from a first end to a second end, the base including a front surface, the stop extends from the front surface and the cushion extends from the front surface, wherein the cushion extends a greater distance from the base than the stop.

9. The armrest assembly of claim 8 , wherein the cushion is a first cushion, and further including a second cushion that extends from the front surface of the base, and wherein the stop is located between the first cushion and the second cushion.

10. The armrest assembly of claim 6 , wherein the cushion includes a cushion arc that extends from the base, and wherein an internal space is defined between the cushion arc and the base.

11. The armrest assembly of claim 10 , further including a surface texture on an external surface of the cushion arc.

12. The armrest assembly of claim 11 , wherein the surface texture includes a raised ridge on the external surface of the cushion arc.

13. The armrest assembly of claim 12 , further including a retainer that extends from a rear surface of the base that is opposite the front surface.

14. The armrest assembly of claim 13 , wherein the retainer is made of a material that is harder than the base.

15. The armrest assembly of claim 10 , wherein the cushion arc includes an internal surface and the internal space is defined between the internal surface and the front surface of the base, the cushion arc is elastically deformed when the armrest is in the latched position, and the internal space remains apart from the front surface when the armrest is in the latched position.

16. The armrest assembly of claim 15 , wherein the armrest engages the stop when the armrest is in the latched position.

17. The armrest assembly of claim 16 , wherein the bumper includes a retainer that extends from a rear surface of the base that is opposite the front surface and engages one of the armrest and the frame.

18. An armrest assembly comprising:
a frame;
an armrest mounted to the frame for relative rotational movement;
a latch adapted so that when the armrest is in a latched position relative to the frame, the latch retains the armrest against movement relative to the frame; and
a bumper mounted on the frame that engages the armrest when the armrest is in the latched position relative to the frame, the bumper including a base that extends from a first end to a second end, the base including a front surface, a stop that extends from the front surface of the base and limits rotation of the armrest in a first direction relative to the frame, and a first cushion and a second cushion that extend from the front surface of the base, are compressed when the armrest is in the latched position, and bias the armrest in a second direction relative to the frame, wherein the first cushion and the second cushion extend a greater distance from the base than the stop.
