Patent US-1913-1104429
Safety seat for airplane with springs and its own wheels to protect the operator in case of a rough landing.
The action of the shock absorber is as follows: In the case of an ordinary landing, when the apparatus comes in contact with the ground, only the wheels of the landing train act. In the case of a sudden landing the wheels 11 fixed on the ends of the rods 5 are intended when coming in turn in contact with the ground, to raise the seats 9, the occupants of which owing to the compensating springs 8 placed below the seats will not experience any shock. In the case of a more violent shock or a fall, the seats will ascend and take hold of the racks 10, maintaining the aviators in the air, thus preventing them from being crushed by the wreckage of the apparatus.
Inventor location: 136 Avenue Parmentier, Paris, France
