Abstract
Abstract A gear selector lock structure is provided and is operative to unlock the gear selector of a vehicle against movement from the non-drive position to the drive position thereof when the lock structure is in the locked position. The lock structure is spring biased toward the locked position and an electric solenoid is operatively associated with the gear lock structure for shifting the latter from the locked position to the unlocked position when the solenoid is electrically actuated. The solenoid is electrically connected to the brake light circuit of the associated vehicle and is, therefore, actuated when the brake pedal of the vehicle is moved from the brake release position to the brake applied position. The gear selector of the associated vehicle and the lock structure include coacting structure whereby the gear selector may cam the lock structure from the locked position thereof to the unlocked position and thereafter release the lock structure for movement to the locked position upon movement of the gear selector from the drive position to the non-drive position in which the gear selector is locked until such time as the brake pedal of the associated vehicle is depressed to activate the solenoid and thereby cause the lock structure to be shifted from the locked position to the unlocked position thereof.
