Abstract:
A load depositing platform for damping impact forces exerted on a load during a load drop, said platform comprising:an upper plate for receiving the load; a lower touch-down plate; at least one air damper element arranged between the upper plate and the touch-down plate, the at least one air damper element having a shell made of a flexible material which forms an interior space and which is fastened on the upper plate at one extremity and on the touch-down plate at an opposite extremity, and having lateral passage openings, whereby a volume of the interior space changes as a function of relative positioning of the upper plate with respect to the touch-down plate, so that air flows into the interior space when the distance of the plates from one another is increased, and is displaced from the interior space for achieving a damping effect when the plates are pressed together; and a scissor-type linkage which connects the upper and lower plates such that they can be moved relative to one another only along a direction toward or away from each other, the upper plate being connected with a parachute which opens during a load drop so that a braking force of the parachute acting upon the upper plate pulls the plates apart.
