Abstract

A door handle assembly for a vehicle includes a bracket mountable to the vehicle door, a handle portion configured to pivotally attach to the bracket and an actuating element pivotally mounted to the bracket. The actuating element connects to a release mechanism of the vehicle door so as to actuate the release mechanism when the actuating element is pivoted relative to the bracket. The door handle assembly may include a counterweight pivotally mounted to the bracket, with the counterweight extending along the bracket, such that the counterweight and the bracket comprise a low profile assembly. The door handle assembly may include an inertial catch pivotally mounted to the bracket, wherein pivotal movement of the handle portion imparts a pivotal movement of the inertial catch during normal operation of the door handle assembly to open the vehicle door.

Claims

1. A door handle assembly for a door of a vehicle, said door handle assembly comprising:

a bracket mountable to the vehicle door;

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

an actuating element pivotally mounted to said bracket, said actuating element connecting to a release mechanism of the vehicle door so as to actuate the release mechanism when said actuating element is pivoted relative to said bracket; and

a counterweight pivotally mounted to said bracket, said counterweight extending along said bracket, said counterweight and said bracket comprising a low profile assembly.

2. The door handle assembly of claim 1, wherein said bracket is mountable to an outer door sheet metal component of the vehicle door that is configured with an indentation for hand clearance, and wherein said counterweight extends along said bracket above and below said hand clearance.

3. The door handle assembly of claim 1, wherein said actuating element includes an arm with a cylindrical protrusion, said cylindrical protrusion engaging said handle portion.

4. The door handle assembly of claim 1, wherein said counterweight extends forwardly along said bracket when said door handle assembly is normally mounted at a vehicle door.

5. The door handle assembly of claim 4, wherein said counterweight includes a pivot axle that is pivotally mounted to said bracket, a connecting arm that is disposed rearwardly of said pivot axle when said door handle assembly is normally mounted at a vehicle door, and at least one weighted element disposed forwardly of said pivot axle when said door handle assembly is normally mounted at a vehicle door.

6. The door handle assembly of claim 5, wherein said at least one weighted element comprises a pair of weighted elements disposed at either side of said bracket.

7. The door handle assembly of claim 1, wherein said actuating element includes a retaining arm for engaging a retaining tab at said bracket to at least initially retain said actuating element in a staging orientation relative to said bracket during assembly of said door handle assembly at the vehicle door.

8. The door handle assembly of claim 7, wherein said counterweight includes a staging arm that is engagable with a staging arm of said actuating element when said actuating element is in said staging orientation so that said counterweight is at least initially retained in a counterweight staging orientation relative to said bracket during assembly of said door handle assembly at the vehicle door.

9. The door handle assembly of claim 8, wherein, when said handle portion is pivoted relative to said bracket, said actuating element is pivoted to disengage said retaining arm from said retaining tab of said bracket, and wherein, when said retaining arm is disengaged from said retaining tab of said bracket, said actuating element is moved along its pivot axis relative to said bracket to an operable position with said retaining arm spaced from said retaining tab and with said staging arm of said actuating element spaced from said staging arm of said counterweight.

10. The door handle assembly of claim 9, wherein, when said actuating element is in said operable position, said actuating element is pivotable about its pivot axis via movement of said handle portion and without engagement of said retaining arm with said retaining tab and without engagement of said staging arm of said actuating element with said staging arm of said counterweight.

11. The door handle assembly of claim 1, wherein said bracket and said counterweight are configured for mounting to a door at either side of a vehicle.

12. The door handle assembly of claim 1, wherein pivotal movement of said handle portion imparts a pivotal movement of said counterweight during normal operation of said door handle assembly to open the vehicle door.

13. A door handle assembly for a door of a vehicle, said door handle assembly comprising:

a bracket mountable to the vehicle door;

a handle portion configured to pivotally attach to said bracket and pivotable between an initial position, where said handle portion is positioned generally along the vehicle door, and an actuating position, where said handle portion is pivoted away from the vehicle door, and wherein pivotal movement of said handle portion actuates a release mechanism of the vehicle door to open the vehicle door; and

an inertial catch pivotally mounted to said bracket, wherein pivotal movement of said handle portion imparts a pivotal movement of said inertial catch during normal operation of said door handle assembly to open the vehicle door.

14. The door handle assembly of claim 13, wherein said inertial catch comprises a first engaging surface and a second engaging surface, wherein acceleration of said vehicle due to a collision or sudden stop, causes said handle portion to engage said first engaging surface to limit opening of the vehicle door, and wherein normal operation of said door handle assembly to open the vehicle door causes said handle portion to engage said second engaging surface and pivotally move said inertial catch.

15. The door handle assembly of claim 14, wherein said handle portion includes a guide pin extending therefrom, and wherein said second engaging surface of the inertial catch comprises a guide channel, wherein said guide pin engages said guide channel and wherein pivotal movement of said handle portion imparts movement of said guide pin along said guide channel to impart pivotal movement of said inertial catch during normal operation of said door handle assembly.

16. The door handle assembly of claim 15, wherein said first engaging surface comprises an outer surface of said inertial catch, and wherein acceleration of said vehicle due to a collision or sudden stop causes said guide pin to not engage said guide channel and to engage said first engaging surface to limit opening of the vehicle door.

17. The door handle assembly of claim 13, wherein said handle portion is pivotable about a generally horizontal pivot axis when said door handle assembly is normally mounted at a door of a vehicle.

18. The door handle assembly of claim 13, wherein said handle portion is pivotable about a generally vertical pivot axis when said door handle assembly is normally mounted at a door of a vehicle.

19. The door handle assembly of claim 13, wherein an actuating element of said door handle assembly is pivotable with said handle portion, said actuating element connecting to the release mechanism of the vehicle door so as to actuate the release mechanism when said actuating element is pivoted relative to said bracket.

20. The door handle assembly of claim 19, wherein one of said handle portion and said actuating element includes a guide pin extending therefrom, and wherein said guide pin engages a guide channel of said inertial catch, and wherein pivotal movement of said handle portion imparts movement of said guide pin which moves along said guide channel to impart pivotal movement of said inertial catch.

21. The door handle assembly of claim 20, wherein said inertial catch includes a guide channel along opposite sides of said inertial catch so that said inertial catch can be used in a door handle assembly of a vehicle door at either side of the vehicle.

22. The door handle assembly of claim 19, wherein said handle portion is unitarily formed with said actuating element.
