ABSTRACT:
An injury-preventing system for automobiles comprises a radiation emitter for emitting electromagnetic radiation, detectors for detecting the electromagnetic radiation and an electronic control circuit which is designed to sense any disruption in the impingement of the electromagnetic radiation on the detectors. The system is located to monitor the space normally occupied by an automobile door. When impingement of the electromagnetic radiation on the detectors is disrupted, as by the placement of a person's hand in the space normally occupied by the automobile door, the electrical circuit activates a mechanical device, for example a solenoid, which places a small rubber rod in the path of the closing door, causing the door to bounce off the rod without closing, avoiding injury to the hand of the person.
