Abstract
A method and system for deforming a drive rod in a door after an impact to the door. An automobile having a door with a door handle, a drive rod, a latching system, a striker, and a drive rod deformation member. The drive rod deformation member can be positioned adjacent to the drive rod. Upon impact to the door, the drive rod deformation member impacts and deforms the drive rod. The deformation of the drive rod can correspond to a compression of the door and the door can be opened by actuating the door handle. However, the deformation of the drive rod prevents the drive rod from controlling the latching system to disengage from the striker through compression of the door.
Claims18
A door latch system comprising:
- a door;
- a door handle located on the door;
- a latch release unit located in the door;
- a drive rod engaged with the door handle and the latch release unit;
- and
- a drive rod deformation member located in the door, wherein upon impact to the door causing deformation to the door, the drive rod deformation member contacts the drive rod at a location along the drive rod between the door handle and the latch release unit and deforms the drive rod at the location along the drive rod between the door handle and the latch release unit, and
- wherein the drive rod remains engaged with the door handle and the latch release unit after the drive rod deformation member deforms the drive rod.
An automobile comprising:
- a frame;
- a striker located in the frame;
- and
- a door connected to the frame and selectively engaged with the striker, the door including
- a latch unit selectively engaged with the striker,
- a latch release unit connected to the latch unit, wherein actuation of the latch release unit controls the engagement of the latch unit with the striker,
- a drive rod engaged to the latch release unit,
- a door handle engaged to the drive rod wherein the drive rod actuates the latch release unit based on a movement of the door handle, and
- a drive rod deformation member wherein upon impact to the door causing deformation to the door, the drive rod remains engaged with the door handle and the latch release unit, and the drive rod deformation member contacts the drive rod at a location along the drive rod between the door handle and the latch release unit and deforms the drive rod.
A method for deforming a drive rod in a door after an impact to the door comprising:
- impacting the drive rod with a drive rod deformation member at a location along the drive rod between a door handle and a latch release unit while the drive rod is connected to the door handle and the latch release unit;
- and
- deforming the drive rod at the location along the drive rod between the door handle and the latch release unit while the drive rod remains connected to the door handle and the latch release unit.
