Joint cover in aircraft

A joint cover in an aircraft has a clamp section and a cover section for covering a joint. The clamp section is used to mount the cover section over the joint. The joint cover conceals the joint and secures the joint from intrusion of foreign objects. One example presents information to passengers, incorporating visual displays or other devices within the cover section. For example, the joint cover may include a cover section and a clamp section of an elastic material that deforms under pressure, concealing the joint even during compression and decompression of the aircraft, which causes movement of the panels defining the joint.
