Abstract

965,809. Laminates. P. VOLPI BASSINI. March 6, 1962 [March 8, 1961; July 1, 1961], No. 8510/62. Heading B5N. Two gas-impervious thermoplastic sheets are welded together to form an inflatable cushion of a plurality of intercommunicating cells, the intercommunications being gaps in the welding seams situated at all or some of the points where the welded edges of the individual cells would intersect if extended. Fig. 1 shows inflatable cushion 20 having individual cells 23 formed by welded seams 24 and intercommunicating by means of gaps 25. Figs. 10 and 11, which are side elevations of a cushion before and after in flation respectively, indicate the reduction in the main dimension of the cushion upon inflation i.e. from L1 to L2.
