BRAKE MECHANISM

摘要

A brake mechanism includes an input, a chassis, a lock and a release mechanism. The input is an axially extending input having first and second ends. The chassis interfaces with the input such that the input is movable relative to the chassis. The lock is coupled to the chassis for constraining movement of the input relative to the lock. The release mechanism is coupled to the lock and is responsive to a force applied relative to the input and the chassis such that when the force is greater than a release force level the release mechanism allows the lock to disengage the input and such that when the force is less than the release force level the release mechanism does not allow the lock to disengage the input.
