Abstract: A motor vehicle anti-theft device adapted to disable the brake pedal of the vehicle. In a first embodiment the device includes an outer housing and an inner shaft member mounted within the housing for relative rotary and telescopic movement. A first clamp structure is journaled on the shaft and a second clamp structure is threaded on the shaft so that as the shaft is rotated in the housing the clamp members are moved toward and away from each other into an out of locking engagement with the brake pedal. The inner shaft and outer housing are slid telescopically relative to each other to firmly engage the fire wall of the vehicle with the clamp members clamped about the brake pedal and a lock structure is provided to preclude relative rotary and relative longitudinal movement of the housing and the shaft.

Abstract: A motor vehicle anti-theft device adapted to disable the brake pedal of the vehicle. The device includes a tubular strut with an opening sized to receive the pedal arm of the brake pedal and a lock bar which may be slid forwardly following movement of the pedal arm into the opening to trap the pedal arm in the opening. The device further includes an actuator rod and a strut rod interconnected by a gear and rack structure so that rearward movement of the actuator rod generates forward movement of the strut rod to plant a foot carried on the forward end of the strut rod against the fire wall of the vehicle following entrapment of the pedal arm. A lock structure is provided to preclude retraction of the lock bar and to preclude retraction of the strut rod.
