ABSTRACT:
A thermal blast shield (64) is located on an aircraft (10) between two adent seats (20 and 22) to be stored in a housing (62) during normal aircraft operation. The thermal blast shield includes cables (84 and 86) passing through fairleads attached to the aircraft and then connected to the seats to pull the shield out of the housing and fully deploy it as the seat is ejected. A break-away mechanism (100, 102) causes the cables to break/separate after the thermal blast shield is fully deployed and jamming/locking mechanisms (104, 106) further control deployment of the thermal blast shield and preclude its post-deployment retraction. The thermal blast shield can be stowed window-shade like or accordianfold-like, and can be formed of a variety of flexible thermal resistant, blast resistant materials.
