Abstract
An air belt apparatus is provided in which a bag is stored while being folded short prior to deployment and inflation. An air belt apparatus includes a bag provided in a part of a seatbelt, a collision detection device, and a gas supply device that supplies deployment gas to the bag. The bag includes a cylindrical portion connected to the gas supply device, and an inflatable portion wider than the cylindrical portion. Prior to deployment and inflation, the inflatable portion is stored on a radial inner side of the cylindrical portion while being turned inside out and folded up to a width substantially equal to a width of the cylindrical portion.
