Abstract: A stretcher supporting structure for use in an airplane, including an elongated stretcher supporting frame adapted to be positioned generally horizontally in the airplane, two leg assemblies connected to the frame adjacent the respective ends thereof, means for connecting the leg assemblies to the floor of the airplane, two straps connected to the frame on opposite sides thereof adjacent each leg assembly, and means for anchoring the other ends of the straps to the airplane with the straps oriented diagonally downwardly to brace the frame and its supporting leg assemblies. The stretcher supporting structure may be installed in the airplane in the space normally occupied by one or two of the seats with which the airplane is equipped, or it may be installed in a similar space with the corresponding seat back or backs folded downwardly and with the stretcher supporting frame located above such seat backs.
