ABSTRACT:
A safety interlock system for automotive vehicles and like devices which have an electrically operable component forming part of the engine of said vehicle or like device. The safety interlock system comprises a plurality of latches in the form of integrated circuits which can only be operated in preestablished sequence with a preestablished code of indicia. When the latches are opened pursuant to the preestablished code with inputs in proper sequence from a plurality of manually operable input switches, the interlock system will be enabled, thereby permitting operation of the electrically operable component and hence said engine. Suitable forms of system time delays and system override devices are provided to enable operation of said engine by others for preestablished time delay periods and under controlled delay conditions. The interlock system of the present invention also includes a unique control system for operating locks such as hood locks and controlling the same, along with the control to the engine. In addition, a unique alarm circuit is also incorporated in the safety interlock system, such that an alarm can be generated when unauthorized opening of any portion of the vehicle occurs.
