A safety ventilation device for a vehicle or other application has a housing having one or more openings which are covered by hinged flaps, and the flaps are connected to one another by connecting elements. The spring is connected to the connecting element or otherwise to the flap such that in the first position the spring holds the flap open and air can pass through the opening. In the second position, when a force is applied to the flap, such as airflow caused by the moving vehicle, compresses the spring and closes the flap. The housing of the device includes a top projection and a bottom channel to facilitate an interference fit between a window and a window or door frame.
