ABSTRACT:
An Airborne Rescue Device utilizes an inverted trough-like elongated element secured to the underbelly of a helicopter and extending in a forward-like direction. The free end of the trough-like member is pivotably secured to one end of an elongated rod whose length is substantially the same as the trough-like member. A pulley, capable of swiveling 360.degree. is rotatably secured to the other end of the rod-like member. A line, passes through a hole in the underbelly of the helicopter adjacent the fixed end of the trough-like member and in turn passes through the pulley. A removable harness may be secured to the free end of the line passing through the opening in the underbelly of the helicopter and through the pulley. Tension is exerted on the cable at selected times so as to perform a rescue operation on individuals slung directly beneath the opening in the underbelly of the helicopter. At other times, when the rod is extended forward of the trough-like member the removable lifevest is utilized to capture persons to be rescued in a plane substantially defined by the underbelly of the helicopter and at a point substantially forward of the cockpit hereof. The rod may then be returned to its stored position. A slip-like clutch, when slipping slightly, allows the rescued person to fall, in a controlled descent downwardly and outwardly from buildings or other vertical structures from which they are to be rescued. The slip-like clutch is then engaged into a locked position so that the tension forces applied to the line permits the line to be drawn inwardly towards the cabin of the helicopter.
