Abstract

A link rod flexibly connecting an exterior door handle of a motor vehicle and a door latching mechanism to prevent actuation of the door latching mechanism as the result of a lateral collision, the link rod comprising: a first section connected to the vehicle door handle; a second section operatively connected to the door latching mechanism; and a lateral connector operatively connecting the first section to the second section. The lateral connector may be a laterally flexible spring, laterally flexible synthetic material, or a hinge point.

Claims

1. A link rod flexibly connecting an exterior door handle of a motor vehicle and a door latching mechanism to prevent actuation of said door latching mechanism as a result of a lateral collision, said link rod comprising:

a first section connected to said vehicle door handle;

a second section operatively connected to said door latching mechanism; and

a lateral connector operatively connecting said first section to said second section;

where said lateral connector comprises a hinge point positioned to flex parallel to a lateral impact and said hinge point comprises;

a pair of stops oriented outward on said hinge point, one adjacent said first section, and one adjacent said second; and

a longitudinal biasing device oriented inward on said hinge point and opposite said pair of stops, said biasing device positioned to bridge between said first section and said second section and maintain said first stop in contact with said second stop.

2. The link rod of claim 1, where said longitudinal biasing device comprises a longitudinally flexible spring.

11. The link rod of claim 1, where said longitudinal biasing device comprises a longitudinally flexible synthetic material.

3. A link rod flexibly connecting an exterior door handle of a motor vehicle and a door latching mechanism to prevent actuation of said door latching mechanism as a result of a lateral collision, said link rod comprising:

a first section connected to said vehicle door handle;

a second section operatively connected to said door latching mechanism; and

a first retainer attached to said first section distal to said door handle;

a second retainer attached to said second section distal to said door latching mechanism; and

a lateral connector embedded in said first retainer and said second retainer operatively connecting said first section to said second section;

where said lateral connector comprises at least one resilient strip.

4. The link rod of claim 3, where said lateral connector comprises a laterally flexible spring.

5. The link rod of claim 3, where said lateral connector comprises a laterally flexible synthetic material.

6. The link rod of claim 5, where said laterally flexible synthetic material is a laterally flexible thermoplastic.

7. The link rod of claim 3, where said lateral connector comprises a hinge point positioned to flex parallel to a lateral impact.

8. The link rod of claim 7, where said hinge point comprises:

a pair of stops oriented outward on said hinge point, one adjacent said first section, and one adjacent said second; and

a longitudinal biasing device oriented inward on said hinge point and opposite said pair of stops, said biasing device positioned to bridge between said first section and said second section and maintain said first stop in contact with said second stop.

9. The link rod of claim 8, where said longitudinal biasing device comprises a longitudinally flexible tube.

10. The link rod of claim 8, where said longitudinal biasing device comprises a longitudinally flexible tube.
