Method of making inflatable cellular assemblies of plastic material |
摘要 |
Pneumatic structural and cushioning material of plastic sheets, bands, and/or tubes, which are compartmentized into a plurality of chambers. The material is capable of convenient and economical storage and shipment in a collapsed state and rapid inflation to an operative state at the point of use. The chambers embody one-way valving arrangements to maintain the chambers in an expanded state over long periods of time, rendering the product useful in cushioning loads during shipment by land, air or water; in safety devices for humans in vehicle bumpers, air cushions, and buoyant devices of all types; and in structural assemblies of either temporary or permanent types to attain heat and sound insulation effects.
