Cushions using cellular materials – foam (convoluted, segmented), flexible matrix, viscoelastic foam or matrix, nondeforming foam or matrix; Cushions containing fluid – viscoelastic fluid, air cushion, water cushion
The key to the debris protection in the design and prototype units was successive layers of Nextel, [11] a material commonly used as insulation under the hoods of many cars, spaced between several-inches-thick layers of open cell foam, similar to foam used for chair cushions on Earth. The Nextel and foam layers cause a particle to shatter as it ...
