ABSTRACT:
A thin-profile multi-compartmented inflatable liner for use as an energy-absorbing device inside a protective headgear or other protective equipment. The multiple air compartments with integral intercommunicating air channels are formed of flexible plastic sheets which are dielectrically heat bonded together. The air compartments have within, resilient foam plastic co-acting bafflements with integral protrusions which interact with the intercommunicating air channels to thereby control the rate of air flow between the air compartments in response to an impact compression of the air compartments. The unique construction provides a thin-profile, light weight, high-energy absorbing liner with strength, durability and reliability to a high degree.
