Abstract

A vehicle access system includes an access opening for the passenger compartment that is closed by a swinging door in combination with an access door. The access door moves through an arc without angling away from the vehicle body and is supported on a hinge assembly that attaches near the center of the door. An arm assembly guides the door throughout its range of positions and maintain the door in an orientation that is substantially parallel to the vehicle body. When the doors are open, an uninterrupted access opening is provided to the area of the second and third seat rows of the vehicle.

Claims

1. A hinge system comprising:

a hinge assembly with a support link having a first end pivotably connected to a first strap and having a second end pivotably connected to a second strap; and

an arm assembly spaced apart from the hinge assembly and having first and second brackets connected by first and second arms wherein the first and second arms each include equivalent offsets placed at different distances from the first bracket so that a segment of the first arm nests under the second bracket when in a closed position of the hinge system.

2. A hinge system according to claim 1 wherein the support link connects to the first strap at a first pivot axis and the support link connects to the second strap at a second pivot axis and further comprising a bumper on the support link between the first and second pivot axes.

3. A hinge system according to claim 1 further comprising a vehicle body having an access opening with a weatherstrip seal around the access opening, wherein the first strap attaches to the vehicle body inboard from the weatherstrip seal.

4. A hinge system according to claim 1 wherein the first strap includes a pair of flanges that pivotably connect to the support link and the second strap includes a pair of arms that pivotably connect to the support link.

5. A hinge system comprising:

a hinge assembly with a support link having a first end pivotably connected to a first strap and having a second end pivotably connected to a second strap, the first strap having a first substantially planar mounting segment and the second strap having a second substantially planar mounting segment the first and second mounting segments continuously remaining substantially parallel during operation of the hinge system; and

an arm assembly having first and second brackets connected by first and second arms wherein the first and second arms each include equivalent offsets placed at different distances from the first bracket so that a segment of the first arm nests under the second bracket when in a closed position.

6. A hinge system according to claim 5 wherein the first substantially planar mounting segment of the first strap is fixed in position and the second substantially planar mounting segment and the second bracket remain parallel to one another throughout operation of the hinge system.

7. A hinge system according to claim 5 wherein the support link connects to the first strap at a first pivot axis and the support link connects to the second strap at a second pivot axis and further comprising a bumper on the support link between the first and second pivot axes.

8. A hinge system according to claim 5 further comprising a vehicle body having an access opening with a weatherstrip seal around the access opening, wherein the first strap attaches to the vehicle body inboard from the weatherstrip seal.

9. A hinge system according to claim 5 wherein the first strap includes a pair of flanges that pivotably connect to the support link and the second strap includes a pair of arms that pivotably connect to the support link.
