Abstract

An improved door assembly for a motor vehicle, especially a pick-up truck having a rear window, whereby the outer panel of the of the rear door is fabricated to form parts of both the side and rear surfaces of the body portion of the vehicle. An operating clearance needed for opening and closing the rear door assembly is positioned on the rear of the vehicle so as to improve the appearance of the vehicle when the vehicle is viewed from the side. The operating clearance on the rear of the vehicle can be positioned to coincide with the frame of a window set into the body of the vehicle to partially obscure the operating clearance when viewing the vehicle from the rear. With specific reference to a pick-up truck, further obscuring of the operating clearance can be obtained by positioning the operating clearance below the window frame behind the bed of the pick-up truck. A plurality of hinges are used to attach the rear door to the body of the vehicle. The pivot axis of the hinges is positioned outward of the operating clearance and away from the aperture in the cab of the pick-up truck so as to improve ingress to and egress from the cab of the pick-up truck.

Claims

1. A door assembly in combination with a motor vehicle having a body with a transversely extending side and a longitudinally extending side, the body further including a rear pillar positioned at the intersection between the laterally extending side and the longitudinally extending side, the door assembly comprising:

a door proper extending forward of the rear pillar and pivotally attached to the rear pillar for movement between a closed position and an open position about a fixed pivot axis, said door proper including an outer panel having a rear portion and a side portion, said rear portion laterally extending inward beyond said pivot axis when said door proper is in said closed position, said a side portion being flush with said transversely extending side when said door proper is in said closed position, and said rear portion being substantially co-planar with said longitudinally extending side when said door proper is in said closed position.

2. The door assembly of claim 1, further including a hinge assembly interconnecting said door proper and said rear pillar, said hinge assembly having first and second hinge elements, said first hinge element fixedly interconnected to said door proper, said second hinge element fixedly interconnected to the rear pillar and pivotally attached to said first hinge element.

3. The door assembly of claim 2, wherein said rear side of said outer panel is adapted to laterally extend in an inboard direction beyond said pivot axis.

4. The door assembly of claim 2, wherein said first hinge element is attached to an inner panel of said door proper.

5. The door assembly of claim 4, wherein said first hinge element is attached to a surface of said inner panel which is substantially parallel to a longitudinal axis of the motor vehicle.

6. The door assembly of claim 5, wherein said second hinge element is attached to a surface of said rear pillar which is substantially perpendicular to the longitudinal axis of the motor vehicle.

20. The door assembly of claim 2, wherein said second element of said hinge assembly is fixedly attached to a rearward facing surface of said rear pillar.

7. A pick-up truck comprising:

a cab having a rear side, a rear pillar, and a lateral side; and

a door positioned forward of the rear pillar and pivotally attached to the rear pillar for movement between a closed position and an open position, said door including an outer panel attached to said rear pillar for pivotal movement about a fixed pivot axis between a closed position and an open position, said door having an outer panel including a side portion which is flush with the lateral side of said cab when said door is in said closed position and a rear portion substantially perpendicular to said side portion, said rear portion substantially co-planar with the rear surface of said cab.

8. The pick-up truck of claim 7, wherein said outer panel has a side portion and a rear portion substantially perpendicular to said side portion, said side portion adapted to be positioned flush with the longitudinally extending side of the motor vehicle and said rear side adapted to be positioned substantially co-planar with the rear side of the cab when said door is in said closed position.

9. The pick-up truck of claim 8, wherein said rear portion of said outer panel inwardly extends beyond said pivot axis.

10. The pick-up truck of claim 9, further including a hinge assembly having first and second hinge elements, said first hinge element fixedly interconnected to said door, said second hinge element fixedly interconnected to the rear pillar and pivotally attached to said first hinge element.

11. The pick-up truck of claim 10, wherein said door includes an inner panel and further wherein said first hinge element is attached to a surface of said inner panel which is oriented substantially parallel to a longitudinal axis of the pick-up truck when the door is rotated to said closed position.

12. The pick-up truck of claim 11, wherein said second hinge element is attached to a service of said rear pillar which is substantially perpendicular to the longitudinal axis of the pick-up truck.

17. The pick-up truck of claim 10, wherein said rear door includes an inner panel, and further wherein said first hinge element is attached to said inner panel.

18. The pick-up truck of claim 17, wherein said first hinge element is attached to a service of said inner panel which is substantially parallel to said first and second laterally sides.

19. The pick-up truck of claim 18, wherein said second hinge element is attached to a service of said rear pillar which is substantially perpendicular to said first and second laterally sides.

21. The pick-up truck of claim 10, wherein said second element of said hinge assembly is fixedly attached to a rearward facing surface of said rear pillar.

13. A pick-up truck comprising:

a cab having a rear pillar, first and second lateral sides, and a rear side including a window and a window frame;

a front door;

a rear door pivotally attached to said rear pillar for pivotal movement about a fixed pivot axis between a closed position and an open position, said rear door having an outer panel including a side portion which is flush with the lateral side of said cab when said rear door is in said closed position and a rear portion substantially perpendicular to said side portion and substantially co-planar with the rear side of said cab; and

said rear side and said rear portion of said outer panel defining an operating space therebetween for facilitating the opening and closing of said rear door.

14. The pick-up truck of claim 13, wherein said operating space positioned to coincide with a substantially vertical side of said window frame so that said operating space is obscured when said cab is viewed from the rear.

15. The pick-up truck of claim 13, further comprised of a truck bed having a front surface positioned in close proximity to said rear side of said cab.

16. The pick-up truck of claim 13, further comprising a hinge assembly interconnecting said rear door and said rear pillar, said hinge assembly having first and second hinge elements, said first hinge element fixedly interconnected to said rear door, said second hinge element fixedly interconnected to said rear pillar and pivotally attached to said first hinge element.

22. The pick-up truck of claim 16, wherein said second element of said hinge assembly is fixedly attached to a rearward facing surface of said rear pillar.
