Mechanical absorption device for installation between primary or secondary structure and interior fitting of airplane, has free-wheel preventing moving-back of drawbar and pin opposite to plate at end of absorption process

摘要

The device has a suspension part formed as a drawbar (12) that exhibits a fastening element (13). The drawbar is arranged movably in a linear free-wheel (21) that stays in mechanical connection with an absorber plate (19). The free-wheel permits a relative movement between the drawbar and the absorber plate for energy absorption, and prevents a moving-back of the drawbar and a pin opposite to the plate at an end of an absorption process by a positive clamping connection between the draw bar and the plate that is made of carbon fiber reinforced or glass-fiber reinforced plastic materials.
