Air pad

摘要

An air pad having a plurality of foam filled air chambers interconnected by at least one air passage connecting at least two of the air chambers to one another. The air passages are also filled with foam whereby the flow of air from one air chamber to another due to impact is restricted. The pad is manufactured by radio frequency welding of two layers of plastic film to one another about a foam body to join the plastic film in the area surrounding each of the air chambers.
