<p>A car accident prevention apparatus is provided to plan a pedestrian's safety by quickly spreading a safety film in the front side of the vehicle according to the speed of the vehicle in an accident. A car accident prevention apparatus comprises a sensing unit(100) and a drive unit(200). The sensing unit senses the impact in an accident. The drive unit spreads a safety film with the sensing unit. The sensing unit comprises a receiver(110), a pneumatic tube, and a connection bar. The connection bar connects the receiver to the drive unit. The drive unit comprises a percussion part and a developing part(240). The percussion part operates with the connection bar. In the developing part, the safety film is spread with the percussion part. The developing part comprises a main body, a column(241), the safety film, and a wire. The safety film is built in the main body. The column is formed at both ends of the main body, so the safety film is spread. The wire is connected to the connection bar in order to construct the column. The receiver pushes the connection bar in the generation of impact. According to the movement of the connection bar, the column stands while the wire is pulled out. The safety film is rapidly spread with the standing of the column.</p> |
