ABSTRACT:
A cable operated interlock system between the gear selector lever (12) of an automatic transmission and the brake pedal (42) restrains the gear selector lever (12) in the Park position until the brake pedal (42) is first depressed. The interlock system includes a shifter cable (68) having one end (70) connected to an L-shaped pedal actuator (62) and another end (72) connected to an inhibitor pin (74) adjacent the gear selector lever (12). A compressible tip (82) is telescopically received over the end of the pedal actuator (62), with a spring (84) trapped therebetween for yielding when the brake pedal (42) returns to its rest position in the event the gear selector lever (12) resides in one of its drive positions. The interlock system may also include an ignition cable (90) extending between an ignition switch (52) of the automobile and the pedal actuator (62). The ignition cable (90) prevents displacement of the pedal actuator (62) and the attached shifter cable (68) unless the ignition switch (52) is in a Run position. Conversely, the ignition cable (90) will not permit the ignition switch (52) to return to its Off position until the gear selector lever (12) has been placed in its Park position.
