Air belt and air belt apparatus

Abstract

To provide an air belt that maintains a flat belt like state, enables passage through an anchor and direct winding to a retractor, and has satisfactory comfort. An air belt includes a bag, a tubular mesh webbing made of a fabric or a textile, and a hollow cover accommodating the mesh webbing. The mesh webbing expands and contracts flexibly in the lateral direction but resists stretching in the longitudinal direction. The hardness of the cover in the lateral direction is greater than the hardness in the longitudinal direction, and the cover bends flexibly in the longitudinal direction but resists bending in the lateral direction. The cover, which is flat and tubular, is formed by longitudinally folding a flat, long sheet along a folding line and seaming the longitudinal sides with a thread, the thread is broken when the bag is inflated.
