ABSTRACT:
A steering column shift mechanism having a wheel brake interlock includes a gear selector shaft moved by a gear selector action initiated by the vehicle operator manually by manipulating a gear selector lever between a park position and at least one drive position. A brake pedal actuates a switch within an electrical circuit containing an electrical solenoid and a power supply to actuate a locking bolt that blocks movement of the selector shaft unless the brake pedal is depressed. The selector lever includes an arm extending into a shift gate containing a system of interconnected recesses corresponding to selected drive positions among which the selector lever 15 moved. A locking bolt, actuated by an electrical solenoid for movement parallel to the axis of the selector shaft, includes a ramp contacted by a spring-loaded bolt mounted for movement laterally with respect to a second bolt, held by a compression spring in contact with the selector lever.
