Abstract

A hinge mechanism for a vehicle door comprising a first arm and a second arm extending between the door section and the vehicle body for supporting the door section during opening and closing thereof. The first arm includes a first shaft for pivotally mounting the door section to the vehicle body and a second shaft for pivotally mounting the door section on the end of the first arm opposite the first shaft. The first shaft is mounted along the vehicle body and is positioned beneath a rearward section of a fixed fender portion. An attaching element rotatably mounts a movable fender portion on the first shaft for rotation with the first arm. The movable fender is adjacent to and substantially beneath the fixed fender portion when the door section is closed. The movable fender also includes an extension projecting forward of the first shaft, the extension defining a path of movement about the first shaft during opening and closing of the door section.

Claims

1. A hinge mechanism for a vehicle door comprising:

a vehicle body including a wheel section, a fender section, and a door section, said fender section being positioned adjacent to said door section and also forward of said door section as defined relative to the length of said vehicle body, said fender section having a fixed fender portion and a movable fender portion, said vehicle body also including a mounting pillar positioned substantially adjacent a forward portion of said door section when said door section is closed, said mounting pillar having a mounting surface;

support means extending between said door section and said vehicle body for supporting said door section during opening and closing thereof, said support means including a first arm and a second arm, each of said arms being substantially straight, said first arm including first shaft means adjacent said mounting pillar for pivotally mounting said door section on said vehicle body and second shaft means for pivotally mounting said door section on an end of said first arm opposite said first shaft means;

said first shaft means being positioned beneath at least a rearward section of said fixed fender portion and being mounted along said vehicle body, said movable fender portion being attached to said first shaft means for rotation with said first arm, said movable fender portion being adjacent to and substantially beneath at least said rearward section of said fixed fender portion when said door section is closed;

said movable fender portion including an extension projecting forward of said first shaft means along the length of said vehicle body when said door section is closed, wherein said extension defines a path of movement about said first shaft means during the opening and closing of said door section; and

said second arm including pivot means for pivotally connecting said second arm to said mounting pillar, wherein said pivot means is mounted along said mounting surface substantially adjacent said second shaft means.

2. The hinge mechanism as defined in claim 1, wherein said door section includes an end panel extending between the exterior and interior of the vehicle along the forward portion of said door section and wherein said second shaft means is mounted along said end panel.

3. The hinge mechanism as defined in claim 1, wherein said first arm is connected to a lower portion of said door section and said second arm is connected to an upper portion of said door section.

4. The hinge mechanism as defined in claim 1, wherein the length of said first arm is less than said second arm, enabling the rearward portion of said door section to extend further away from said vehicle body, when said first arm is pivoted forward of said first shaft means.
