Device for securely covering air vents in special-purpose vehicles

摘要

A device for reliably covering air vents in special vehicles. The device consists of parallel strips of L-shaped or S-shaped structural section. The object is to reliably prevent not only foreign bodies but also migrating splinters thereof from penetrating inside. The end of each strip that points inside the vehicle has additional structures and parts thereof, some of which extend essentially at an angle to the end of the strip.
