Safety device for motor vehicles
First Claim
1. Motor vehicle safety apparatus comprising:
- a solenoid having a plunger-like rod, said rod being moveable in response to the energization of said solenoid,a safety plate, one end of said safety plate being coupled to a free end of said rod, the other end of said safety plate being engageable with an operating arm of the throttle or fuel injection system of the motor vehicle in response to the energization of said solenoid, andenergizing means for energizing said solenoid, said energizing means being coupled to the gear train of the motor vehicle such that when the gear train is disposed out of park or neutral positions, said rod is moved so that said safety plate is not engaged with the operating arm, and when the gear train is in the park or neutral positions said rod is moved so that the other end of said safety plate prevents the operation of the operating arm.

Abstract
Safety device for motor vehicles utilizes a cam-like plate and linkage to prevent accidental acceleration of a motor vehicle when disengaging the vehicle'"'"'s shift lever from the park or neutral position. The apparatus employs an electrical circuit to detect the position of the shift lever and the activation and deactivation of the brake foot pedal. Only after placing the vehicle into any drive position other than park or neutral, and releasing a pedally operated brake pedal, will the linkage permit the throttle of the motor vehicle to move from its idle position to any position selected by the operator upon later application of an operating force to the accelerator pedal. In this manner, the operator is assured that the motor vehicle will not accidentally be caused to lurch forward or backward at high speed.
