Abstract

A tailgate step has a hinge assembly and a step assembly. One side of the hinge assembly attaches to the inside panel of the tailgate near its upper edge. The other side of the hinge assembly attaches to the step frame. In one form, Z pins connect the two sides of the hinge assembly. The step frame is U shaped where the bight of the U is the step portion. The tailgate step has a stored position against the inside panel of the tailgate and an in-use position across the tailgate edge and vertically downward when the tailgate is open.

Claims

1. A step assembly useful with a tailgate supported for hinged movement between a horizontally oriented down position and a vertically oriented up position, said step assembly including a step frame mounted for movement relative to said tailgate between a deployed position and a stored position, said step assembly comprising:

a bearing block configured for attachment to the inner surface of a tailgate proximate to the tailgate upper edge, said bearing block defining a tailgate hinge axis;

said step frame comprising first and second elongate legs oriented parallel to, and horizontally spaced from, one another, each of said legs defining an upper end and a lower end;

a step member connected between said first and second legs proximate to the lower ends thereof;

first and second step bearings respectively located on said first and second legs proximate to the upper ends thereof and defining a step hinge axis;

first and second pivot rods each comprising an integral member defining first and second hinge pins oriented substantially parallel to and offset from one another; and

wherein

said first and second pivot rod first hinge pins are coupled to said bearing block for rotation through approximately 270°

about said tailgate hinge axis; and

said first and second pivot rod second hinge pins are respectively coupled to said first and second step bearings for allowing rotation of said step frame relative to said step hinge axis;

whereby when said tailgate is in said down position, said step frame is movable between (1) a deployed vertically oriented position with said step hinge axis outboard of said tailgate upper edge and said step member vertically below said step hinge axis and (2) a stored horizontally oriented position with said step hinge axis inboard of said tailgate upper edge and said step member proximate to the inner surface and lower edge of said tailgate.

2. The step assembly of claim 1 wherein each of said pivot rods comprises an essentially Z-shaped member defining a central connecting portion having said first and second hinge pins extending in opposite directions therefrom.

3. The step assembly of claim 1 wherein said step frame is comprised of a tubular member bent to form a U-shape defining said first and second elongate legs and said step member.

4. The step assembly of claim 1 wherein each of said legs has a length greater than two times the offset between said hinge pins.
