Claim:
A foldable ramp for evacuation of a vehicle, the ramp comprising: a first pair of spaced apart primary side members each having a first end hingedly connectable to a frame attached to the vehicle and a second end opposed the first end; a second pair of spaced apart secondary side members, each of the secondary side members having opposed first and second ends, the second end of each secondary side member being connected to the second end of a respective one of the primary side members; a primary flipping panel extending between the primary side members and having a first end pivotally connected to the primary side members and a second end displaceable relative to the side members; a secondary flipping panel extending between the secondary side members and having a first end pivotally connected to the secondary side members and a second end displaceable relative to the side members, the second end of the secondary flipping panel being hingedly connected to the second end of the primary flipping panel; and a fixed panel extending between the side members of one of the first and second pairs, the fixed panel being fixedly attached to the side members of the one of the first and second pairs adjacent the first ends thereof, the fixed panel being adjacent the first end of the flipping panel connected to the side members of the one of the first and second pairs; wherein the ramp is configurable between a folded and a deployed position, the panels in the deployed position forming a ramp surface for evacuation of the vehicle, and the panels in the folded position being stacked one against the other.
