Emergency release system for automobile side door
An emergency release system is disclosed for use with a side door of an automobile. The emergency release system may include a latch, a cable, and a handle connected to the latch via the cable. The handle may be pivotal through a first range to a stop, translatable to surmount the stop, and pivotal through a second range after surmounting the stop to release the latch.
1. An emergency release system for a side door of an automobile, the emergency release system comprising:
a housing;
a latch;
a cable; and
a handle mounted to the housing, the handle connected to the latch via the cable, the handle having an operation for releasing the latch via the cable,
where the operation comprises the handle being pivotal about a pivot point in a first direction through a first range to abut a stop located on the housing, the handle being translatable in a second radial direction away from the pivot point in a manner to surmount the stop, and the handle being pivotal in the first direction through a second range after surmounting the stop to thereby release the latch.
2. The emergency release system of claim 1 , wherein the first range is about 25° to about 65°.
3. The emergency release system of claim 2 , wherein the first range is about 40° to about 50°.
4. The emergency release system of claim 3 , wherein the second range is about the same as the first range.
5. The emergency release system of claim 1 , further including a reset blocking mechanism configured to inhibit unintentional movement of the handle after the handle is pivoted through the second range.
6. The emergency release system of claim 1 , further including a spring configured to provide resistance against movement of the handle.
7. The emergency release system of claim 1 , wherein, when the handle is exposed to elevated forces, the handle is configured to break away from the side door with the cable remaining connected to the handle.
8. The emergency release system of claim 1 , further including a pivot pin capable of connecting the handle to the side door.
9. The emergency release system of claim 8 , wherein the pivot pin is configured to fail before failure of the handle when the handle is exposed to elevated forces.
10. The emergency release system of claim 1 , further including a fluorescent surface operatively connected to a side of the handle that is visible only when the handle is in an actuated position.
