IPC: B60R25/04
Filed: 1983-05-31
Abstract: PURPOSE:To place restrictions on a sphere of running in a stolen car and thereby make an escape hard or impossible, by limiting an accelerator pedal to its pedaling extent by means of an engaging device when the car reaches to either a setting traveling distance or a setting car speed or a setting time after its being stolen. CONSTITUTION:When an emergency switch 12 is operated, a detector 11 comes into a state of being operated. When the detector 11 reaches to either the specified traveling distance or the specified running speed or the elapse of the speci fied time, it excites a solenoid 10, attracting a plunger 10a toward this solenoid. As a result, an engaging pin 8 of an engaging device 3 hits an actuator 2 interlocking an accelerator pedal 1 by dint of energizing force of a spring 9. And, this pin 8 enters inside a groove 2a of the actuator 2 whereby even when an auto lifter tries to step on the accelerator pedal with good force, he fails to step on it more than that as the pin 8 engages with a wall of the groove 2a. Therefore, the stolen car is compelled to go slowly and slowly.
