Abstract

A vehicle includes a door with an interior door cavity, as well as a lock rod and another item of a locking system, an impact beam, an attack member and a push member, all housed in the interior door cavity. The impact beam crosses the other item from laterally between the other item and the door. The attack member faces the lock rod from laterally between the door and the lock rod. The push member, along the impact beam, faces the other item from laterally between the other item and the door and laterally beyond the impact beam. When the door collapses when compromised by a side impact event, the door carries the attack member for attacking action on the lock rod. The door additionally carries the push member for counterpart pushing action on the other item. A connection between the lock rod and the other item thus breaks.

First claim

What is claimed is:

1. A vehicle, comprising:
a door with an interior door cavity;
a lock rod and another item housed in the interior door cavity as part of a locking system for the door, the lock rod and the other item sharing a connection therebetween, with the other item supporting the lock rod for movement;
an impact beam housed in the interior door cavity and crossing the other item from laterally between the other item and the door; and
an attack member and a push member housed in the interior door cavity, the attack member facing the lock rod from laterally between the door and the lock rod, and the push member, along the impact beam, facing the other item from laterally between the other item and the door and laterally beyond the impact beam; whereby
when the door collapses when compromised by a side impact event, the door carries the attack member to apply attacking force to the lock rod, and carries the push member to apply counterpart pushing force to the other item, to thus break the connection between the lock rod and the other item.

2. The vehicle of claim 1 , wherein when the door collapses when compromised by a side impact event, the door carries the push member to apply counterpart pushing force to the other item in coordination with counterpart pushing force applied by the impact beam to the other item.

3. The vehicle of claim 1 , wherein the impact beam crosses both an outboard push site and an inboard push site at the other item, the push member faces the other item at the inboard push site from laterally beyond the impact beam, and when the door collapses when compromised by a side impact event, the door carries the push member to apply counterpart pushing force to the other item at the inboard push site in coordination with counterpart pushing force applied by the impact beam to the other item at the outboard push site.

4. The vehicle of claim 3 , wherein the outboard push site and the inboard push site laterally orthogonally flank the connection between the lock rod and the other item.

5. The vehicle of claim 1 , wherein the other item supports the lock rod for laterally orthogonal movement.

6. The vehicle of claim 1 , wherein when the door collapses when compromised by a side impact event, the door carries the attack member in a laterally inside-to-outside direction to apply attacking force to the lock rod, and carries the push member in a laterally outside-to-inside direction to apply counterpart pushing force to the other item.

7. The vehicle of claim 1 , wherein the connection between the lock rod and the other item is subject to snap-apart breaking, and with the attacking force applied by the attack member to the lock rod, and the counterpart pushing force applied by the push member to the other item, the connection between the lock rod and the other item thus snaps apart.

8. The vehicle of claim 7 , wherein the connection between the lock rod and the other item is a snap-together connection.

9. The vehicle of claim 1 , wherein the other item is a latch assembly.

10. The vehicle of claim 9 , wherein the vehicle further includes a handle assembly housed in the interior door cavity as part of the locking system for the door, the handle assembly and the lock rod sharing a connection therebetween, with the handle assembly and the latch assembly together supporting the lock rod by opposing ends thereof for laterally orthogonal movement.

11. The vehicle of claim 1 , wherein the attack member is a standalone structure fastened to the door as part of a disabling system for the lock rod.

12. The vehicle of claim 1 , wherein the push member is a standalone structure fastened to at least one of the door and the impact beam as part of a disabling system for the lock rod.

13. A door for a vehicle, comprising:
an inner door panel and an outer door panel defining an interior door cavity therebetween;
a handle assembly, a latch assembly with a latch and a linkage with a lock rod housed in the interior door cavity as part of a locking system for the door, the handle assembly and the lock rod sharing a connection therebetween, and the lock rod and the latch assembly sharing a connection therebetween, with the handle assembly and the latch assembly together supporting the lock rod by opposing ends thereof for laterally orthogonal movement by which the linkage operates to actuate the latch;
an impact beam housed in the interior door cavity and crossing both an outboard push site and an inboard push site at the latch assembly from laterally between the latch assembly and the outer door panel;
an attack member housed in the interior door cavity, the attack member projecting into the interior door cavity from the inner door panel, and facing the lock rod from laterally between the inner door panel and the lock rod; and
a push member housed in the interior door cavity along the impact beam, the push member projecting into the interior door cavity from the outer door panel around and laterally beyond the impact beam, and facing the latch assembly at the inboard push site from laterally between the latch assembly and the outer door panel; whereby
when the door collapses when compromised by a side impact event, the inner door panel carries the attack member to apply attacking force to the lock rod, and the outer door panel carries the push member to apply counterpart pushing force to the latch assembly at the inboard push site in coordination with counterpart pushing force applied by the impact beam to the latch assembly at the outboard push site, to thus break the connection between the lock rod and the latch assembly.

14. The door of claim 13 , wherein the outboard push site and the inboard push site laterally orthogonally flank the connection between the lock rod and the latch assembly.

15. The door of claim 13 , wherein a closing distance between the impact beam and the outboard push site is substantially the same as a closing distance between the push member and the inboard push site, and when the door collapses when compromised by a side impact event, the outer door panel carries the push member to apply counterpart pushing force to the latch assembly at the inboard push site that initiates at substantially the same time as counterpart pushing force applied by the impact beam to the latch assembly at the outboard push site.

16. The door of claim 13 , wherein the connection between the lock rod and the latch assembly is subject to snap-apart breaking, and with the attacking force applied by the attack member to the lock rod, and the counterpart pushing force applied to the latch assembly at the inboard push site by the push member in coordination with counterpart pushing force applied by the impact beam to the latch assembly at the outboard push site, the connection between the lock rod and the latch assembly thus snaps apart.

17. The door of claim 16 , wherein the connection between the lock rod and the latch assembly is a snap-together connection.

18. The door of claim 13 , wherein the attack member is a standalone structure fastened to at least one of the inner door panel and the impact beam as part of a disabling system for the lock rod.

19. The door of claim 13 , wherein the push member is a standalone structure fastened to the outer door panel as part of a disabling system for the lock rod.
