Abstract
A motor vehicle interlock device (10) has an actuating assembly (11) connected by a push-pull control cable (13) to a dead bolt throw assembly (12). The dead bolt throw assembly (13) has a dead bolt (60) which is engageable with a lock engaging lug (20) of a transmission, operating range, drive selector. A plunger (30) is biased by a first compression spring (39) into abutting engagement with the lever arm (15) of a foot-operated brake such that when the foot-operated brake pedal is applied, the plunger (30) is urged toward the lever arm (15) The first end (46) of the core (48) in a push-pull control cable (13) is attached to the plunger (30), and the second end (73) of the core (48) is attached, by a lost motion connector (75), to a dead bolt (60). As such, when the plunger (30) follows the lever arm (15) the push-pull control cable (13) translates the dead bolt (60) out of engagement with the lock engaging lug (20), thereby freeing the transmission, operating range, drive selector. An embodiment of an actuating assembly utilized with the interlock (10) is also presented as being used in conjunction with a combined brake light and cruise control switch assembly (90).
