ABSTRACT:
A net is mounted to hang freely from the end of a pair of pivotally secured arms extending from the underside of a helicopter. The arms and net hang down in a vertical position when the helicopter is in flight and a motorized lifting mechanism raises the arms and net into a forward horizontal position for particular rescue missions or on land. A movable weight is guided along a tube extending adjacent the rear of the helicopter to balance the weight of the arms and net. A resilient bumper is mounted on the front of the net and a locking mechanism secures the arms in the horizontal position. The lifting mechanism is mounted close to the center of gravity of the helicopter to avoid balance problems.
