A brake/shift interlock for an automatic transmission shift control mechanism

摘要

A brake/shift interlock assembly (10) is mounted on the steering column (11) in operational cooperation with a column mounted shift control mechanism for an automatic transmission. The brake/shift interlock assembly includes a pivotal latch (24) for selectively locking the detent bar (16) of the shift control mechanism in the park position, a solenoid assembly (28) with an actuator rod (42) for magnetically holding the latch in the locking position, a return spring (44) for normally biasing the actuator rod and latch in the locking position, a spring lever (26) for selectively moving the latch to an unlock position and an electrical control circuit for energizing the solenoid when the ignition system is on and the foot brake switch is open.
