Abstract
Abstract The present invention provides a novel form of automotive safeguard for protecting occupants when a traffic accident happens. This safeguard comprises a transparent and stretchable shock absorbing plate disposed between a windshield and a front seat in such a way to leave a given interval with respect to the windshield. This safeguard also includes a heater provided to the space defined by the interval, which is used for heating and circulating air inside the space to prevent development of clouding on the windshield when heating the inside of a car during the winter months.
