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.

A method of deploying a vehicle step assist comprising first and second support arms which are connected to a vehicle and rotatable with respect to said vehicle about respective first and second axes which are oriented generally parallel to the ground and which pass through fixed locations in said first and second support arms, respectively, wherein said support arms are connected to a step member and rotatable with respect to said step member about respective third and fourth axes which are generally parallel to said first and second axes, said support arms 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 support arms extending upward toward said vehicle from said step member when said step member is in said deployed position, said method comprising:
A vehicle step assist, comprising:
A method of fixing in a retracted position a vehicle step assist comprising first and second support arms which are connected to a vehicle and rotatable with respect to said vehicle about respective first and second axes which are oriented generally parallel to the ground and which pass through fixed locations in said first and second support arms, respectively, wherein said support arms are connected to a step member and rotatable with respect to said step member about respective third and fourth axes which are generally parallel to said first and second axes, said support arms allowing said step member to move between said retracted position and a deployed position in which the entirety of said step member is lower than said first and second axes and located downward and outboard from said retracted position, at least one of said support arms extending upward toward said vehicle from said step member when said step member is in said deployed position, said method consisting of:
