    摘要： A support is disclosed comprising a belt which encircles a wearer's waist. The belt which is inflatable has an on-board inflation pump and may be used for weight lifting. The inflatable weight lifting belt includes a bladder defined by a single chamber having inflation and deflation mechanisms which allow the wearer to selectively adjust the amount of air in the bladder. The bladder has an oblong portion which is positioned on the belt so that when the belt is worn, the oblong portion is positioned adjacent to the wearer's lower back for support. An elongated portion of the bladder extending through the aperture of the belt is integrally formed with inflation and deflation mechanisms on the other side of the belt. In the preferred embodiment, the inflation mechanism comprises a pump and a one-way valve and the deflation mechanism comprises an exhaust valve.

    摘要： A cushioning member for an article of footwear. The cushioning member is a flexible bladder having a fluidly interconnected heel chamber and forefoot chamber. The bladder is disposed above the sole and beneath the wearer's foot to provided added cushioning to the wearer. The bladder contains air at slightly above ambient pressure and can be formed by thermoforming or by welding two sheets of resilient, flexible material together. A connecting passage fluidly connects the heel chamber and the forefoot chamber. The connecting passage is narrow to control the flow of air between the two chambers.

    摘要： A cushioning member for an article of footwear is provided having a series of interconnected chambers filled with ambient or slightly pressurized air. An impedance is provided between selected chambers, in order to restrict the flow of air between the chambers. The shape and structure of the impedance determines the nature of the air flow between chambers, such that the cushioning member can be tailored for various types of activities and body weights, by offering varying degrees of cushioning.

    摘要： A support and cushioning system for an article of footwear. The system includes a resilient insert disposed between a midsole and an outsole of a shoe. The resilient insert includes several chambers disposed in a heel portion of the resilient insert These chambers are fluidly interconnected to each other via periphery passages. The resilient insert also includes several chambers disposed in a forefoot portion of the resilient insert. These chambers are also fluidly interconnected to each other. A connecting passage connects the chambers in the heel portion and the chambers in the forefoot portion of the resilient insert. A bladder having a fluidly interconnected heel chamber and forefoot chamber is also inserted above the midsole to provided added cushioning to the wearer. In one embodiment, the resilient insert contains air at ambient pressure and the bladder contains air at slightly above ambient pressure.

    摘要： An athletic shoe is described, provided with an inflatable tongue or bladder for a more secure fit to the user's foot. The bladder may include a plurality of chambers with a valve disposed therebetween to selectively inflate the chambers. The inflatable tongue or bladder has a lightweight pump disposed thereon. Inflatable footwear having an inflation bag under the foot is also disclosed. The inflation bag is formed by two sheets of material that are welded together. Interior welds are provided to moderate the thickness of the inflation bag. A foam layer having apertures is positioned adjacent to the inflation bag. The apertures overlie the interior welds and are sized larger than the interior welds. Also described is a slider valve that enables selective inflation of individual bladder chambers.
