A step assembly is provided having a step frame mounted for movement relative to a mounting surface between a deployed position and a stored position (or between a stored position and a deployed position), and at least one boss, the boss having a notch for holding the step frame in the deployed position. The step frame preferably has at least two legs oriented parallel to each other, and horizontally spaced from one another, each of the legs defining an upper end and a lower end, an axle connected at the upper end of the at least two legs, and a step member connected between the at least two legs proximate to the lower ends thereof.

1. A step assembly comprising:a step frame mounted for movement relative to a mounting surface between a deployed position and a stored position comprising: at least two legs oriented parallel to each other, and horizontally spaced from one another, each of said legs defining an upper end and a lower end; an axle connected at said upper end of said at least two legs; and a step member connected between said at least two legs proximate to the lower ends thereof; and at least one boss, wherein said at least one boss comprises at least one of the following two notches: a first notch that is configured for releasably holding said step frame in said deployed position and a second notch that is configured for releasably holding said step frame in said stored position, wherein said at least one boss comprises no more than two notches configured for holding said step frame, and wherein said step frame is configured for releasing from at least one of said notches along an axis of said axle by an axial force. 2. The step assembly of claim 1, further comprising: a first spring operating on the step frame, wherein said first spring applies a force for moving said step frame from the deployed position to the stored position.3. The step assembly of claim 2, wherein the first spring automatically retracts the step frame from the deployed position to the stored position when the step frame is released from the first notch.4. The step assembly of claim 2, further comprising: a second spring operating on the step frame, wherein said second spring applies a force for holding said step frame in the first notch in a deployed position.5. The step assembly of claim 1, further comprising: a mounting bracket for mounting the step assembly to a surface, wherein the axle and the at least one boss engage said mounting bracket.6. The step assembly of claim 5, wherein the mounting bracket is mounted such that said step frame may be rotated from a first position to a second position.7. The step assembly of claim 1, wherein at least one of the step member and at least one of the at least two legs comprises: an operating tab for moving the step frame between the stored position and the deployed position.8. The step assembly of claim 1, wherein the step assembly is configured to mount to a vehicle bumper.9. The step assembly of claim 8, wherein the step assembly is configured to mount such that the step assembly is substantially hidden from view when the step frame is in a stored position.10. The step assembly of claim 1, wherein the step assembly is configured to mount on at least one of the passenger side of a vehicle and the driver side of the vehicle such that a bed space may be accessed from at least one of the passenger side of the vehicle and the driver side of the vehicle.11. The step assembly of claim 1, wherein the step assembly is configured to mount such that the step assembly lies substantially within a bumper when in the stored position.12. The step assembly of claim 1, wherein at least one of said at most two notches is configured to engage at least one of said legs.13. The step assembly of claim 1, wherein at least one of said at most two notches has a width and is configured to engage at least one of said legs having an approximately round cross section and having a diameter not greater than said width.14. The step assembly of claim 1, further comprising: a first spring operating on the step frame, wherein said first spring applies a force for moving said step frame from the stored position to the deployed position.15. The step assembly of claim 14, wherein said first spring applies said force for moving said step frame from the stored position to the deployed position by spring rotation, and wherein said first spring applies a force for holding said step frame in the first notch in the deployed position by spring compression.16. The step assembly of claim 1, further comprising a spring operating on the step frame, wherein said spring applies a force for holding said step frame in the first notch in the deployed position by spring compression, and wherein said spring applies a force for moving said step frame from the deployed position to the stored position by spring rotation.17. A step assembly comprising:a frame mounted for movement relative to a mounting surface between a deployed position and a stored position comprising: a leg having an upper end and a lower end; and an axle connected at said upper end of said leg; at least one of the following two notches: a first notch that is configured for releasably holding said frame in said deployed position and a second notch that is configured for releasably holding said frame in said stored position; and a spring for holding said frame in said at least one notch, wherein said step assembly comprises no more than two notches configured for holding said frame, and wherein said frame is configured for releasing from at least one of said notches along an axis of said axle by an axial force. 18. The step assembly of claim 17, wherein the frame has one of a substantially “L” shape, a substantially “U” shape, a substantially “Δ” shape, a substantially “∇” shape, and a substantially trapezoidal shape.19. The step assembly of claim 17, wherein the frame is configured to mount to a bumper of a vehicle.20. The step assembly of claim 19, wherein the frame is configured to mount to a bumper of a vehicle such that the step assembly is substantially hidden from view when the frame is in the stored position.
