ABSTRACT:
An inflatable air bag for cushioning restraint of an occupant in a motor vehicle is fabricated from a single pattern piece cut from a thin, strong, lightweight, flat segment of flexible sheet material by sewing or seaming along cut edges of the pattern in a designated sequence to provide an air bag having a shape when fully inflated, providing a maximum effective cushioning surface for engaging the vehicle occupant. The single pattern piece is symmetrical with respect to bisecting longitudinal and transverse central axes and includes central portion forming a large, occupant engaging surface area, pairs of side edge portions at opposite ends of the central portion forming opposite side walls of the inflated air bag and pairs of throat portions at opposite ends of the longitudinal central axis for forming an inlet throat of the air bag for receiving inflation gas.
