Abstract

A door handle assembly for use with a vehicle door comprising a door paddle including an actuation arm, supported to pivot about a first axis such that lateral acceleration of the paddle and actuation arm relative to the door produces a first moment about the first axis, and masses engaged with the actuation arm and supported to pivot about a second axis, the masses being arranged such that lateral acceleration of the masses relative to the door produces a second moment about the first axis that is substantially equal in magnitude and opposite in direction to the first moment.

Claims (20)

1. A door handle assembly coupled to a vehicle door comprising:

a door paddle supported to pivot about a first axis;

an actuation arm secured to the door paddle;

a first mass engaged with the actuation arm and supported to pivot about a second axis; and

a second mass engaged with the actuation arm and supported to pivot about a third axis spaced from the second axis, the masses being arranged such that outboard displacement of the door paddle causes the masses to pivot in a first direction producing a first moment about the first axis and to open the vehicle door, and an outboard acceleration of the masses causes the masses to pivot in a second direction producing a second moment about the first axis that is substantially equal in magnitude and opposite in direction to the first moment to prevent the opening of the vehicle door.

2. The assembly of claim 1 wherein the first direction is inboard and the second direction is outboard.

3. The assembly of claim 1 wherein the first axis is substantially perpendicular to the second and third axes.

4. A method of operating a door handle assembly on a vehicle door comprising the steps of:

(a) pivotally supporting a door paddle about a first axis;

(b) securing an actuation arm to the door paddle and to first and second masses;

(c) pivotally supporting the first mass to pivot about a second axis;

(d) pivotally supporting the second mass to pivot about a third axis spaced from the second axis; and

(e) arranging the masses such that outboard displacement of the door paddle causes the masses to pivot in a first direction producing a first moment about the first axis and to open the vehicle door, and an outboard acceleration of the masses causes the masses to pivot in a second direction producing a second moment about the first axis that is substantially equal in magnitude and opposite in direction to the first moment to prevent opening of the vehicle door.

5. The method of claim 4 , wherein in step (e) the first direction is inboard and the second direction is outboard.

6. A door handle assembly coupled to a vehicle door comprising:

a door paddle supported to pivot about a first axis;

first and second actuation arms secured to the door paddle;

a first mass engaged with the first actuation arm and supported to pivot about a second axis; and

a second mass engaged with the second actuation arm and supported to pivot about a third axis spaced from the first axis, the masses being arranged such that outboard displacement of the door paddle causes the masses to pivot in a first direction producing a first moment about the first axis and to open the vehicle door, and an outboard acceleration of the masses causes the masses to pivot in a second direction producing a second moment about the first axis that is substantially equal in magnitude and opposite in direction to the first moment to prevent the opening of the vehicle door.

7. The assembly of claim 1 wherein the first direction is inboard and the second direction is outboard.
