DISPOSITIF DE POSITIONNEMENT D'UN OBJET PAR RAPPORT À UN SUPPORT PAR DES ÉLÉMENTS DE COUSSIN D'AIR GONFLABLE, PROCÉDÉ DE FONCTIONNEMENT DU DISPOSITIF ET PROCÉDÉ DE DÉPLACEMENT D'UN OBJET

摘要

The device comprises a plurality of inflatable air cushion members (6) of a flexible but non- stretchable air tight sheet material (1) in hose-connection (11) with an inflation tool (12). Each inflatable air cushion member (6) is formed as a bag unit comprising opposite layers of said sheet material (1, 1′) provided face to face and joined along an edge area (4) to form a double layer edge. Surface modification of the cushion members, for example by a sleeve or pouch into which the cushion members are inserted, is used to adjust the properties of the device for an optimised lifting process.
