摘要

A mechanical interlock device, particularly for use in conjunction with a motor vehicle key ignition lock 10 and automatic gear selector lever 11 (Figure 1), includes a control cable assembly 31 interconnecting a bell crank pawl 25 on the key ignition lock and a pivotable cam plate 34 on the automatic gear selector lever. The bell crank pawl 25 is biassed away from a recess 30 in an axially reciprocable slide bar 22 of the lock and enters the recess only when rotated by a corresponding rotation of the cam plate 34 produced by a cam follower pin 36 on a selector lever 13 co-acting with an arcuate slot 35 in the cam plate 34 following movement of the selector lever 13 from a PARK position. With the bell crank pawl 25 projecting into the recess, axial retraction of the slide bar 22 is restrained and the lock may not be rotated to a KEY OUT position. Upon returning the selector lever 13 to the PARK position the bell crank pawl 25 is enabled to rotate out of the recess 40 and thus full retraction of the slide bar 22 to the KEY OUT position is then possible. In addition, with the lock device in the KEY OUT position the slide bar 22 is fully retracted and the bell crank pawl 25 is prevented from rotating into the recess 40, thereby preventing a corresponding rotation of the cam plate 34. The inter-action of a ramp portion of the arcuate slot 35 on the cam plate 34 with the cam follower pin 36 on the selector lever 13 is such that if the cam plate is not free to rotate, the selector lever 13 cannot be moved from the PARK position.
