AIR BELT AND AIR BELT APPARATUS

摘要

An air belt having mesh webbing sufficiently strong and sufficiently expandable in the circumferential direction of a bag-shaped belt and an air belt apparatus including the air belt are provided. An air belt includes a folded member being a bag-shaped belt folded in a band shape and mesh webbing covering the folded member of the bag-shaped belt. The mesh webbing hardly expands in the longitudinal direction of the air belt, and is flexibly expandable in the circumferential direction of the bag-shaped belt. The mesh webbing is made of a raschel-knitted material. The knitted material is arranged such that the extending direction of knot portions of yarn threads and corresponds to the longitudinal direction of the air belt.
