Abstract: A protective device for a door gap between a door and a door frame in the body of an armored, specially protected vehicle. The device prevents projectile splinters from penetrating the interior of the vehicle, and is intended to reduce the door aperture as little as possible when the door is opened. For this purpose, partitions extend from the frame of the door into the door gap. As a result, the gap-covering armor that extends into the door opening area beyond the door frame when the door is opened has a relatively limited extent in the free door aperture area. One of the projectile-deflecting projections on the frame of the door is an anti-splinter strip mounted on the inside of the door and projecting into the door gap, said strip preventing the parts of a broken-up projectile from penetrating the interior of the vehicle and/or deflecting those parts that do penetrate into areas that are noncritical for the vehicle occupants.
