ABSTRACT:
A gasproof inflatable cushion with a hole which perforates it and whose edge is provided with an inner valve part on the inside and with an outer valve part on the outside such that the hole is enclosed and the construction is gasproof. The inner valve part is provided with a through-opening which ends in the cover hole and has such inner dimensions that the cover material can be pulled through the inner valve part and the outer valve part is provided with a through-part which ends in the cover hole at an inner opening and which ends outside at an outer opening. Gas pumped into the outer opening or extracted from the outer opening is pumped into or extracted from the inside of the cover through the through-part of the outer valve part and the through-opening of the inner valve part. The sealed edges of the covers forming the cushion are located on the inside.
