ABSTRACT:
A vehicle cover alarm apparatus is provided for use on a vehicle equipped with an "electronic security system". The alarm apparatus comprises a bracket which carries an electrical switch. An electrical conductor electrically connects the switch to the electronic security system on the vehicle. A cable is connected to the switch and extends from the switch outwardly of the vehicle. The cable is adapted for connection to a vehicle cover and when so connected, creates a tension on the cable which causes the switch to move to a first switch position. A biasing means such as a spring biases the cable against the action created by the tension on the cable. Thus, when the vehicle cover is released from the cable, the spring will automatically bias the switch to its initial switch position. In this way, the alarm apparatus and the vehicle security system are set in an alarm condition, an unauthorized release of the cable from the vehicle cover will cause the movement of the switch and thereby energize an alarm forming part of the vehicle security system.
