A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, a second arm, a motor and a stop. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The motor is drivingly connected to the first arm such that a rotation of the motor causes rotation of the first arm about its first end and moves the stepping member from a retracted position to an extended position, or vice versa. The stop is located within the range of motion of the second arm such that the second arm bears against the stop when the stepping member is in the extended position. The first and second arms are situated such that the first arm is loaded in compression and the second arm is loaded in tension when the stepping member is in the extended position and a load is placed upon it. In another embodiment, a retractable vehicle step assist comprises a rigid frame, a forward planar linkage pivotably connected to the frame along a forward upper connection width, and a rearward planar linkage pivotably connected to the frame along a rearward upper connection width. The retractable vehicle step further comprises a rigid step member having a stepping deck. The step member is pivotably connected to the forward planar linkage along a forward lower connection width, and is pivotably connected to the rearward planar linkage along a rearward lower connection width and on a side of the forward planar linkage opposite the stepping deck. The stepping deck is substantially wider than any of the forward upper connection width, the rearward upper connection width, the forward lower connection width, and the rearward lower connection width.

1. A retractable vehicle step, comprising:a step member having a stepping deck and a support bracket portion extending inboard from said stepping deck;a first support arm; anda second support arm;said first support arm and said second support arm connectable with respect to an underside of a vehicle so as to be pivotable about a first pivot axis and a second pivot axis, respectively;said first support arm and said second support arm connected to said step member so that said first support arm and said second support arm are pivotable with respect to said step member about a third pivot axis and a fourth pivot axis, respectively, said fourth pivot axis located inboard from said third pivot axis;said first support arm and said second support arm allowing said step member to move between a retracted position and a deployed position downward and outboard from said retracted position;at least one of said first support arm and said second support arm extending downward and outboard from said first and second pivot axes, respectively, when said step member is in said deployed position;wherein said stepping deck is substantially wider than said support bracket portion;wherein said support bracket portion provides a recessed area into which said first support arm is inserted at said third pivot axis. 2. The retractable vehicle step of claim 1, wherein both of said first support arm and said second support arm extend downward and outboard from said first and second pivot axes, respectively, when said step member is in said deployed position. 3. The retractable vehicle step of claim 1, wherein said support bracket portion includes a lower surface, and said recessed area is bounded by said lower surface. 4. The retractable vehicle step of claim 1, wherein at least one of said first support arm and said second support arm further comprises a first end which forms at least two spaced-apart coaxial bearing members suitable for pivotable connection with respect to said underside of said vehicle. 5. The retractable vehicle step assist of claim 4, wherein said at least one of said first support arm and said second support arm further comprises a second end which forms at least two spaced-apart coaxial bearing members pivotably connected to said step member. 6. The retractable vehicle step of claim 1, wherein said support bracket portion provides an opening in an upper surface of said support bracket portion into which opening said first support arm is inserted at said third pivot axis. 7. The retractable vehicle step of claim 6, wherein:said first support arm comprises a unitary support arm defining an inboard surface and an outboard surface, a maximum distance between said inboard surface and said outboard surface defining a first thickness, said first support arm defining a substantially vertical first side and a substantially vertical second side, a maximum distance between said first side and said second side defining a first width, said first width being substantially greater than said first thickness. 8. The retractable vehicle step of claim 7, wherein:said second support arm comprises a unitary support arm defining an inboard surface and an outboard surface, a maximum distance between said inboard surface and said outboard surface defining a second thickness, said second support arm defining a substantially vertical first side and a substantially vertical second side, a maximum distance between said first side and said second side defining a second width, said second width being substantially greater than said second thickness. 9. The retractable vehicle step of claim 6, wherein said upper surface of said support bracket portion extends outboard of said third pivot axis. 10. The retractable vehicle step of claim 9, wherein said support bracket portion further comprises a lower surface opposite said upper surface. 11. The retractable vehicle step of claim 10, wherein said lower surface of said support bracket portion extends outboard of said third pivot axis. 12. The retractable vehicle step of claim 6, wherein said second support arm is inserted into said opening at said fourth pivot axis. 13. The retractable vehicle step of claim 6, wherein said support bracket portion comprises a first side segment and a second side segment located on opposite sides of said opening, wherein said first side segment and said second side segment comprise a unitary member.
