Abstract

A door handle assembly for opening a door of a vehicle includes a handle portion and a lever or actuating member for actuating or releasing a latch mechanism of a vehicle door. The door handle assembly includes fewer components than known door handles and is reversible or suitable for use at either side of the vehicle. The door handle assembly may include a counterweight and lever mechanism at the base of the door handle assembly, such that the components do not extend substantially into the door cavity. The counterweight may be positioned rearwardly and outwardly of a pivot axis of the lever mechanism when the handle is at an initial or non-opening position, thereby providing enhanced retention of the door handle assembly during vehicle collisions.

Claims

1. An exterior door handle assembly mounted to a door of a vehicle, said exterior door handle assembly comprising:

a base portion mountable to the vehicle door so as to be at an exterior portion of the vehicle door and at an exterior side of the vehicle, at least a portion of said base portion extending laterally outwardly from the exterior side of the vehicle when said base portion is mounted to the door of the vehicle;

a handle portion configured to pivotally attach to the vehicle door and pivotable between an initial position, where said handle portion is positioned generally along the exterior portion of the vehicle door, and an actuating position, where said handle portion is pivoted away from the exterior portion of the vehicle door; and

a lever portion pivotally mounted to said base portion, said lever portion including a counterweight and a connector arm, said connector arm engaging said handle portion and connecting to a release mechanism of the vehicle door, a substantial portion of said counterweight being within said base portion and external of the exterior portion of the vehicle door when said handle portion is in said initial position, said lever portion pivoting in response to pivotal movement of said handle portion, whereby pivotal movement of said handle portion toward said actuating position pivots said lever portion and actuates the release mechanism to open the vehicle door.

2. The exterior door handle assembly of claim 1, wherein said substantial portion of said counterweight is positioned rearwardly and laterally outwardly from a pivot axis of said lever portion when said handle portion is mounted to the vehicle door and in said initial position so that said counterweight functions to pivot said lever portion toward a non-opening position to limit opening of the vehicle door during a collision or sudden stop of the vehicle.

3. The exterior door handle assembly of claim 1, wherein said connector arm of said door handle assembly extends a lateral distance into the vehicle door when said handle portion is in said initial position, said connector arm of said door handle assembly extending approximately the same lateral distance into the vehicle door when said handle portion is moved to said actuating position.

4. The exterior door handle assembly of claim 1, wherein said handle portion includes an engaging portion that engages an engaging arm of said lever portion.

5. The exterior door handle assembly of claim 4, wherein said engaging arm extends from a pivot axis of said lever portion, said connector arm extending from said pivot axis.

6. The exterior door handle assembly of claim 5, wherein said counterweight extends from said connector arm.

7. The exterior door handle assembly of claim 6, wherein said connector arm extends at least partially into the door and said substantial portion of said counterweight extends into said base portion when said handle portion is in said initial position.

8. An exterior door handle assembly mounted to a door of a vehicle, said exterior door handle assembly comprising:

a base portion mountable to the vehicle door so as to be at an exterior portion of the vehicle door and at an exterior side of the vehicle;

a handle portion configured to pivotally attach to the vehicle door and pivotable between an initial position, where said handle portion is positioned generally along the exterior portion of the vehicle door, and an actuating position, where said handle portion is pivoted away from the exterior portion of the vehicle door; and

a lever portion pivotally mounted to said base portion and pivotable about a pivot axis, said lever portion including an engaging arm, a connector arm and a counterweight, said connector arm connecting to a release mechanism of the vehicle door;

wherein a substantial portion of said counterweight is disposed laterally outboard of said pivot axis and at least partially within said base portion and at least partially external of the exterior portion of the vehicle door when said handle portion is in said initial position so that said counterweight functions to pivot said lever portion toward a non-opening position to limit opening of the vehicle door during a collision or sudden stop of the vehicle; and

wherein said engaging arm is engaged by said handle portion and pivotally moved by said handle portion as said handle portion is moved between said initial position and said actuating position, and wherein pivotal movement of said handle portion toward said actuating position imparts pivotal movement of said engaging arm which in turn imparts pivotal movement of said connector arm about said pivot axis to actuate the release mechanism of the vehicle door.

9. The exterior door handle assembly of claim 8, wherein said counterweight extends from said connector arm.
