Abstract

A door assembly is provided having an ergonomic egress handle. The egress handle includes a door release lever that is pivotally connected to an automotive vehicle door about an axis that is generally perpendicular to the door for unlatching the door so that the door may be opened relative to the vehicle. A method is also provided for operation of the door assembly.

Claims

1. A door assembly for an automotive vehicle comprising:

a door operably connected to an automotive vehicle for permitting access into the vehicle in an open orientation of the door, and for limiting access into the vehicle in a closed orientation of the door;

a latching mechanism mounted to the door for latching the door to the vehicle in the closed orientation;

a door release lever operatively connected to the latching mechanism so that actuation of the door release lever unlatches the latching mechanism for opening the door, the door release lever being pivotally connected to the door for rotation about an axis that is generally perpendicular to the door; and

an armrest mounted to an interior side of the door, the armrest having a forward portion facing a forward direction of the vehicle, wherein the door release lever is mounted to the armrest forward portion.

4. The door assembly of claim 1 wherein the door release lever has a generally arcuate cross section with a hollow underside to be gripped manually.

5. The door assembly of claim 1 wherein the armrest has a recess formed therein and the door release lever is mounted within the armrest recess.

6. The door assembly of claim 5 further comprising a cable disposed within the door assembly, the cable being coupled to the door release lever second end and the latching mechanism so that manual actuation of the door release lever translates the cable and consequently unlatches the latching mechanism.

7. The door assembly of claim 1 wherein the door release lever is mounted upon the armrest.

8. The door assembly of claim 7 wherein the door release lever is oriented flush with the armrest in a retracted orientation thereof for providing a streamlined automotive interior.

9. The door assembly of claim 7 wherein the door release lever is manually actuated by extending a distal end of the door release lever away from the armrest.

10. The door assembly of claim 7 wherein the door release lever includes a first distal end displaced external from the armrest to be gripped and actuated manually, and a second end disposed within the armrest and operably connected to the latching mechanism for unlatching the door.

11. The door assembly of claim 1 further comprising:

a door panel mounted to an interior side of the door, wherein the door release lever is mounted upon the armrest.

12. The door assembly of claim 11 wherein the armrest further comprises:

an armrest cushion having an arm receiving surface that is displaced generally horizontal and adjacent to the door panel; and

an armrest console extending from the armrest cushion at an incline in a forward direction.

13. The door assembly of claim 12 wherein the armrest console further comprises at least one switch for operating at least one accessory associated with the door assembly.

14. The door assembly of claim 12 wherein the door release lever is mounted to a forward distal end of the armrest console.

15. The door assembly of claim 14 wherein the forward distal end of the armrest console has a semi-cylindrical cross-section.

16. The door assembly of claim 15 wherein the door release lever has a semi-cylindrical cross-section, and the armrest console forward portion includes a recess formed therein to receive the door release lever generally flush with the armrest console forward portion in a latched position of the door release lever.

17. The door assembly of claim 16 wherein the door release lever is pivotally connected to the armrest console forward portion and the door release lever includes a distal end whereby the door release lever is actuated by extending the distal end away from the armrest console forward portion, thereby rotating the door release lever and consequently unlatching the latching mechanism.

2. A door assembly for an automotive vehicle comprising:

a door operably connected to an automotive vehicle for permitting access into the vehicle in an open orientation of the door, and for limiting access into the vehicle in a closed orientation of the door;

a latching mechanism mounted to the door for latching the door to the vehicle in the closed orientation;

a door release lever operatively connected to the latching mechanism so that actuation of the door release lever unlatches the latching mechanism for opening the door, the door release lever being pivotally connected to the door for rotation about an axis that is generally perpendicular to the door; and

an armrest mounted to an interior side of the door, the armrest having a generally arcuate forward portion facing a forward direction of the vehicle, wherein the door release lever is generally arcuate and is mounted to the armrest forward portion.

3. A door assembly for an automotive vehicle comprising:

a door operably connected to an automotive vehicle for permitting access into the vehicle in an open orientation of the door, and for limiting access into the vehicle in a closed orientation of the door;

a latching mechanism mounted to the door for latching the door to the vehicle in the closed orientation; and

a door release lever operatively connected to the latching mechanism so that actuation of the door release lever unlatches the latching mechanism for opening the door, the door release lever being pivotally connected to the door for rotation about an axis that is generally perpendicular to the door;

wherein the door is pivotally connected to the vehicle, and a passenger opens the door assembly from inside the vehicle by applying a force to the door release lever in a direction that is generally parallel to the door, and by subsequently applying a force to the door that is not parallel to the pivotal connection of the door.
