ABSTRACT:
An interlock mechanism for mechanically locking a steering column mounted, automatic transmission selector lever in the "park" position by means of a detent locking device which has a first element mounted on the stationary portion of the steering column adjacent a second element on the collar which rotates as the transmission selector lever is moved. The movable detent of one element is spring biased to engage an opening in the other element only when the transmission is in the "park" position. The detent is removed manually or otherwise to allow movement of the transmission out of "park" and may include a signaling device to indicate that the transmission is not in "park" when turning off the ignition, leaving the vehicle, etc.
