Retractable vehicle step
View Patent ↗A retractable step for use with a vehicle comprises a stepping member having an upper stepping surface, a first arm, and a second arm. 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 first and second arms can be generally planar linkages.
1. A retractable vehicle step assist comprising:
a rigid frame configured to attach to an underside of a vehicle;
a support assembly connectable with respect to the rigid frame so as to be pivotable about a first axis oriented generally parallel to the ground and a second axis oriented generally parallel to the ground, respectively; and
a step member having an upper stepping surface, said support assembly pivotable with respect to said step member about a third axis and a fourth axis, respectively, said second axis located inboard from said first axis;
said support assembly allowing said step member to move between a retracted position and a deployed position; and
wherein, as said step assist is viewed in a plane perpendicular to said first axis, said support assembly initially moves downward as said step member moves from the deployed position to the retracted position.
2. The retractable vehicle step assist of claim 1 , wherein deployed position of the retractable vehicle step assist is downward and outboard from said retracted position.
3. The retractable vehicle step assist of claim 1 , wherein the entirety of said upper stepping surface is located outboard of said first axis when said step member is in said deployed position and at least a portion of said upper stepping surface is located inboard of said second axis when said step member is in said retracted position.
4. The retractable vehicle step assist of claim 1 , wherein said first axis is spaced from said third axis by a first distance, and said second axis is spaced from said fourth axis by a second distance, as said step assist is viewed in a plane perpendicular to said first axis, and said first distance and said second distance are unequal.
5. The retractable vehicle step assist of claim 4 , wherein said first distance is greater than said second distance.
6. The retractable vehicle step assist of claim 1 , wherein said step member defines a plane for supporting at least a forefoot, said plane takes on a first orientation when said step member is in said deployed position and a second orientation when said step member is in said retracted position, said second orientation being inclined with respect to said first orientation.
7. The retractable vehicle step assist of claim 6 , wherein said upper stepping surface has an inboard end and an outboard end, and said outboard end is located upward from said inboard end when said plane is in said second orientation.
8. The retractable vehicle step assist of claim 1 , wherein said step member further comprises a support bracket connected to and extending upward and inboard from said upper stepping surface when said step member is in said deployed position, said third and fourth axis extending through said support bracket.
9. The retractable vehicle step assist of claim 1 , wherein said fourth axis is positioned above and inboard said third axis in said deployed position.
10. The retractable vehicle step assist of claim 1 , wherein the rigid frame is mounted to a substantially vertical surface of the underside of the vehicle.
11. A vehicle comprising the retractable vehicle step assist of claim 1 .
