Materials, Fabrication, and Packs for Air Cushions 710018

Urethane or neoprene coated over a lightweight nylon fabric appears to be the prime candidate for air cushion material. Evaluations to date show that an air cushion fabricated with vulcanized seams from a neoprene coated ripstop nylon produces the most reliable unit. However, urethane coated nylon also offers potential for a sewn or heat sealed unit. A typical automotive crash pad construction, ABS/vinyl, over an integral urethane foam pad with suitable tear lines, produces satisfactory decorative covers and packs for automotive installation.
