ABSTRACT:
This invention relates to an automotive vehicle's windshield expressly designed and purposely made to move forward or open automatically and to get out of the way of the vehicle's passengers who may be thrown against it by virtue of Newton's First Law Of Motion and the inertial property of matter when their speeding vehicle suddenly stops, and not designed or made to move or open manually, robotically, nor with any mechanical device for the purpose of ventilation or external communication.
The principal parts of the embodiment of this invention consist of (a) an automatically opening and forward moving windshield and its supporting bars or arms, hinges, ratchet cylinder (a unique elongated form of ratchet wheel) that permits the windshield to open up speedily in accidents and to close down gradually afterward) and a matching pawl with flexible teeth instead of ones that do not yield; and (b) a protective air net made of strong cordage thickly coated or encased in substance containing air bubbles, such as the foam rubber, and its retaining spool, roller, and pulling cords. Since the pulling cords are securely fastened to the bottom frame of the automatically forward moving and upward opening windshield, when the latter moves forward or swings upward in response to Newton's First Law of motion, the said protective net is pulled down between the passengers and the erstwhile position of the windshield.
