Abstract

An accessibility system for providing access into or out of a vehicle includes a pan defining a securement area. The pan includes a first end, a second end, and a support surface. A ramp assembly includes a first segment and a second segment hingedly coupled to the first segment. The ramp assembly is pivotally coupled to and deployable from the pan near the second end. A tailgate assembly is detachably secured and pivotally coupled to the pan such that during deployment of the ramp assembly, the ramp assembly is pivotable about a first axis and the tailgate assembly is pivotable about a second axis parallel to and offset from the first axis.

First claim

What is claimed is:

1. An accessibility system for providing access into or out of a vehicle, the accessibility system comprising:
a pan defining a securement area, the pan including a first end, a second end, and a support surface;
a ramp assembly including a first segment coupled to a second segment, the ramp assembly pivotally coupled to the pan proximate the second end and pivotable relative to the pan between a stowed position in which the ramp assembly extends toward the first end of the pan and is adjacent to the support surface, a vertical position in which the ramp assembly is generally perpendicular to the support surface, and a deployed position in which the ramp assembly extends from the vehicle;
a tailgate assembly pivotally coupled to the pan proximate the second end and operably coupled to the ramp assembly such that when the ramp assembly is in the deployed position, the tailgate assembly is disposed below and apart from the first segment; and
a linkage having a first end pivotally coupled to the tailgate assembly and a second end slidably coupled to the ramp assembly,
wherein the second end of the linkage is received within a track fixed to the first segment of the ramp assembly and is slidable along the track when the ramp assembly is moved between the stowed position and the vertical position, and
wherein the second end of the linkage is locked in a predetermined position within the track when the ramp assembly is moved between the vertical position and the deployed position.

2. The accessibility system of claim 1 , wherein the ramp assembly is pivotable about a first axis and the tailgate assembly is pivotable about a second axis parallel to and offset from the first axis.

3. The accessibility system of claim 2 , further including a damping member coupled to the tailgate assembly, wherein the damping member dampens pivoting of the tailgate assembly about the second axis.

4. The accessibility system of claim 1 , further comprising a lock member engageable with the second end of the linkage to automatically lock the second end of the linkage upon reaching the predetermined position.

5. The accessibility system of claim 1 , further comprising a latch configured to secure the tailgate assembly to the pan.

6. The accessibility system of claim 5 , further comprising an actuator coupled to the latch, wherein the actuator is operable to disengage the latch to permit the tailgate assembly to pivot about a first axis parallel to and offset from a second axis about which the ramp assembly pivots.

7. The accessibility system of claim 1 , wherein the tailgate assembly is configured to support a portion of the vehicle bumper.

8. An accessibility system for providing access into or out of a vehicle, the accessibility system comprising:
a pan defining a securement area, the pan including a first end, a second end, and a support surface;
a ramp assembly including
a first segment, and
a second segment hingedly coupled to the first segment, wherein the ramp assembly is pivotally coupled to and deployable from the pan near the second end;

a tailgate assembly detachably secured and pivotally coupled to the pan such that during deployment of the ramp assembly, the ramp assembly is pivotable about a first axis and the tailgate assembly is pivotable about a second axis parallel to and offset from the first axis; and
a plate having a first portion pivotally coupled to the tailgate assembly and a second portion slidably coupled to the ramp assembly, wherein the plate spans a gap defined between the ramp assembly and the tailgate assembly when the ramp assembly is in a stowed position in which the ramp assembly extends toward the first end of the pan and is adjacent to the support surface.

9. The accessibility system of claim 8 , further comprising a linkage having a first end pivotally coupled to the tailgate assembly and a second end slidable within a track fixed to the ramp assembly.

10. The accessibility system of claim 8 , further comprising a latch configured to detach the tailgate assembly from the pan for rotation about the second axis.
