What is claimed is: 1. A retractable step for use with a vehicle, said retractable step comprising: a first arm connectable with respect to an underside of said vehicle so as to be rotatable about a first axis generally orthogonal to a direction of access to said vehicle via said retractable step;
What is claimed is: 1. A retractable step for use with a vehicle, said retractable step comprising: a first arm connectable with respect to an underside of said vehicle so as to be rotatable about a first axis generally orthogonal to a direction of access to said vehicle via said retractable step; a second arm connectable with respect to said underside of said vehicle so as to be rotatable about a second axis generally parallel to said first axis, wherein said first axis is located above said second axis; a step member comprising a stepping surface and a support bracket extending generally from said stepping surface toward said arms; said step member connected to said first arm and rotatable with respect to said first arm about a third axis, said step member connected to said second arm and rotatable with respect to said second arm about a fourth axis, an end portion of said first arm being received in an opening formed in said support bracket near said third axis, an end portion of said second arm being received in said opening near said fourth axis; said step member being moveable between a retracted position and a deployed position suitable for providing access to said vehicle; said stepping surface having a lateral dimension which is oriented generally orthogonal to said direction of access to said vehicle, when said step member is in said deployed position; said third axis and said fourth axis being generally parallel to said lateral dimension when said step member is in said deployed position, said fourth axis being located inward of and above said third axis when said step member is in said deployed position; wherein, when said step member is in said deployed position, placement of a load on said stepping surface tends to urge said step member further toward said deployed position. 2. The retractable step of claim 1, wherein said support bracket comprises a unitary member. 3. The retractable step of claim 1, wherein said deployed position of said step member is located downward and outward from said retracted position. 4. The retractable step of claim 1, wherein said first arm comprises a generally flat, platelike member having a relatively broad face extending along said first axis. 5. The retractable step of claim 1, wherein said stepping surface is substantially wider than said support bracket. 6. A retractable step for use with a vehicle, said retractable step comprising: a first arm connectable with respect to an underside of said vehicle so as to be rotatable about a first axis generally orthogonal to a direction of access to said vehicle via said retractable step; a second arm connectable with respect to said underside of said vehicle so as to be rotatable about a second axis generally parallel to said first axis; a step member comprising a stepping surface and a support bracket extending generally from said stepping surface toward said arms; said step member connected to said first arm and rotatable with respect to said first arm about a third axis, said step member connected to said second arm and rotatable with respect to said second arm about a fourth axis, an end portion of said first arm being received in an opening formed in said support bracket near said third axis, an end portion of said second arm being received in said opening near said fourth axis; said step member being moveable between a retracted position and a deployed position downward and outward from said retracted position; said fourth axis being located inward of and above said third axis, and above said stepping surface, when said step member is in said deployed position. 7. The retractable step of claim 6, wherein said support bracket comprises a unitary member. 8. The retractable step of claim 6, wherein said stepping surface is substantially wider than said support bracket. 9. The retractable step of claim 6, wherein said first axis is located above said second axis. 10. The retractable step of claim 6, wherein said support bracket extends above said stepping surface when said step member is in said deployed position. 11. The retractable step of claim 10, wherein said third and fourth axes are located above said stepping surface when said step member is in said deployed position. 12. A retractable step for use with a vehicle, said retractable step comprising: a first arm connectable with respect to an underside of said vehicle so as to be rotatable about a first axis generally orthogonal to a direction of access to said vehicle via said retractable step; a second arm connectable with respect to said underside of said vehicle so as to be rotatable about a second axis generally parallel to said first axis; a step member comprising a stepping surface and a support bracket extending generally from said stepping surface toward said arms; said step member connected to said first arm and rotatable with respect to said first arm about a third axis, said step member connected to said second arm and rotatable with respect to said second arm about a fourth axis, an end portion of said first arm being received in an opening formed in said support bracket permitting movement of said first arm about said third access, an end portion of said second arm being received in an opening of said support bracket permitting movement of said second arm about said fourth axis; said step member being moveable between a retracted position and a deployed position downward and outward from said retracted position; said fourth axis being located inward of and above said third axis, and above said stepping surface, when said step member is in said deployed position. 13. The retractable step of claim 12, wherein said support bracket comprises a unitaly member. 14. The retractable step of claim 12, wherein said stepping surface is substantially wider than said support bracket. 15. The retractable step of claim 12, wherein said first axis is located above said second axis. 16. The retractable step of claim 12, wherein said support bracket extends above said stepping surface when said step member is in said deployed position. 17. The retractable step of claim 16, wherein said third and fourth axes are located above said stepping surface when said step member is in said deployed position. 18. The retractable step of claim 12, wherein said first and second arms are received within the same opening. 19. The retractable step of claim 1, wherein said first, second, third and fourth axis are each defined by a pin. 20. The retractable step of claim 6, wherein said first, second, third and fourth axis are each defined by a pin. 21. The retractable step of claim 12, wherein said first, second, third and fourth axis are each defined by a pin.
