ABSTRACT:
Tamper deactivating pivotal motion transmission assembly, e.g. between a motor vehicle deck lid exterior lock and interior latch, comprising a bearing, e.g. containing a bore concentric to an axis; an actuator mounted thereon for pivotal movement about the axis at an activating position, e.g. for releasing the latch, and for deviating movement out of operative relation with the bearing to a deactivating position, e.g. preventing latch release; an urging mechanism, e.g. a spring, urging the actuator to deactivating position; and a pivotal force transmitting shaft, preferably of curved cross section and flexible and extending through the bore, e.g. axially connected at its head end to the actuator for conjoint movement therewith relative to the bearing and having its tail end remote therefrom and arranged for attachment under tension at a remote reference point, e.g. to the lock, for maintaining the actuator at the activating position against the urging mechanism force and for receiving a pivotal force applied to the tail end, e.g. by the lock, for pivoting the shaft and actuator, e.g. to release the latch; whereby upon disturbing the tension attachment disposition of the tail end at or relative to the reference point, e.g. lock, the urging mechanism will urge the actuator to deactivating position;
