Passive self-adaptive memory cushion and its preparation method

Abstract

The invention discloses a non-source adaptive memorial cushion and the preparing method, the cushion mentioned comprising an air permeable enveloping closed shield, which is equipped with nylon button and air impermeable inner closed shield, which is equipped with air valve and filled with material of sponge of different material quality or composite sponge of different design or sponge of low shearing force produced specially or sponge, nine-pore sponge or seven-pore sponge designed by individual chosen according to individual parameter and demand, by controlling aerating and gas-discharging of the air valve to make the cushion interface shape memory the feature of the individual user. The preparing method comprises: establishing the mathematical model of reflecting the relation between the interfacial pressure, cushion deformation and shearing depth by checking and taking the individual feature parameter, and changing into CAD / CAM software preparing model, the non-source adaptive memorial cushion can be used in household soft furniture such as sofa cushion and bed cushion, and the sitting device, waist cushion and bolster in wheel chair, coach, train and plane.
