Size adjustable cup holder in a motor vehicle

1. A cup holder for a motor vehicle comprising:

a receptacle having an opening, a base and a sidewall having an exterior and an interior surface that extends from the base to the opening, an interior surface defining an aperture for receiving the container into the receptacle, the base defining a plane;

at least one protrusion pivotably mounted to the sidewall and extending through an opening in the sidewall, wherein the protrusion being rotatable about an axis, the axis being substantially perpendicular with respect to the plane defined by the base, the protrusion being movable between a fully extended position through the opening and a fully retracted position;

a biasing member coupled to the protrusion and biasing the protrusion toward the fully extended position;

wherein the protrusion further includes a first stop preventing the rotational movement of the protrusion beyond the fully retracted position;

wherein the first stop engages an exterior surface of the sidewall; and

wherein the protrusion further comprises of a second stop thereby preventing the rotational movement of the protrusion beyond the fully extended position; and

wherein the second stop engages an exterior surface of the sidewall.

2. The cup holder for a motor vehicle of claim 1 , wherein the biasing member is a continuous elastic member extending around the sidewall.

3. The cup holder for a motor vehicle of claim 1 , wherein the protrusion further comprises an inclined surface substantially facing the opening thereby facilitating entrance of the container to the receptacle.

4. The cup holder for a motor vehicle of claim 1 , wherein the protrusion further comprises an inclined surface substantially facing the base thereby facilitating exit of the container from the receptacle.

5. The cup holder for a motor vehicle of claim 1 , wherein the first stop is a flange extending from the protrusion and sized so as not to extend through the opening.

6. The cup holder for a motor vehicle of claim 1 , wherein the second stop is a flange extending from the protrusion and sized so as not to extend through the opening.

7. The cup holder for a motor vehicle of claim 1 , wherein the protrusion includes an axle located adjacent an exterior surface of the sidewall, the axle being oriented generally perpendicular with regard to the base.

8. The cup holder for a motor vehicle of claim 7 , wherein the axle is rotatably retained by C-shaped clips, the C-shaped clips extending from the exterior surface of the sidewall.

9. The cup holder for a motor vehicle of claim 7 , wherein the biasing member engages a lever arm extending from the axle.

10. The cup holder for a motor vehicle of claim 9 , wherein the biasing member is received within a channel defined by the lever arm.
