Abstract
An inertial lock for the electric actuated release mechanism of a door latch, said release mechanism comprising a solenoid and plunger and said inertial lock comprising a spring biased inertial ring disposed on an extended portion of the solenoid and operably associated with spring biased locking tabs operable to lock the plunger in place during conditions which would provide forces that might undesireably actuate the release mechanism, such as certain vehicle accident conditions. This inertial lock is set within the confines of a conventional electric latch release mechanism, not requiring additional space, and features have been incorporated into the design to ease assembly of the electric actuated release mechanism and aid in the collection of flux from the solenoid.
