Electric control circuit for safety apparatus in automotive vehicles
First Claim
1. In an electric control circuit for a safety apparatus of an automotive vehicle, which control circuit comprises an electric power source, normally open switch means to be closed in the occurrence of a vehicle collision, electrically operated actuator means connected in series with said power source through said switch means to actuate said safety apparatus upon closure of said switch means, and a storage condenser connected in parallel with said switch means and said actuator means;
- the improvement comprising;
a first electric element interposed between the positive electrodes of said power source and condenser for permitting an electric current from said power source to said condenser and said actuator means and interrupting an electric current from being discharged from said condenser through said element; and
a second electric element interposed between the negative electrodes of said power source and condenser for permitting an electric current to flow through said actuator means to the negative electrode of said power source and interrupting the flow of a reverse electric current.

Abstract
An electric control circuit for a safety apparatus of an automotive vehicle comprises an electrically operated actuator connected in series with an electric power source through a normally open switch to actuate the safety apparatus upon closure of the switch and is provided with a storage condenser connected in parallel with the switch and actuator to supply electric energy to the actuator upon disconnection of a conductor between the power source and actuator. In the control circuit, a first diode is connected at its anode in series with the positive electrode of the power source and at its cathode in series with the positive electrode of the condenser to interrupt an electric current discharged from the condenser therethrough, and a second diode is connected at its cathode in series with the negative electrode of the power source and at its anode in series with the negative electrode of the condenser to interrupt a reverse electric current flowing therethrough.
