- Figure 1 is a sectional view of an aircraft lifting cushion of the prior art.
- This cushion typically comprises two walls 1, 2 woven coated for sealing and vulcanized hot. These woven walls 1, 2 are connected on their periphery by a thickening 3 of rubber. These walls 1, 2 are also interconnected by polyamide threads 4 which when they are tensioned by inflation of the cushion are parallel and regularly spaced from each other.
- These son 4 are of identical length so as to maintain the walls 1, 2 parallel. This ensures the application of a uniform lifting pressure on the structure of the aircraft under which the cushion is placed.
- woven articles having a complex shape such as poufs filled with polystyrene beads, chair covers, etc., result from the assembly of initially separate textile pieces which are then joined, for example, by sewing to confer its definitive form to the article.
