1. A warp knitted fabric for an air belt for enclosing a bag belt folded into a shape of a band and constituting an inflatable air belt comprising:
- a knitting yarn; and
an additional yarn inserted into the knitting yarn, wherein the additional yarn comprises;
a first additional yarn positioned to prevent the warp knitted fabric from stretching in the longitudinal direction; and
a second additional yarn positioned to prevent the warp knitted yarn from stretching in the transverse direction, wherein the second additional yarn has a thickness less than the first additional yarn;
wherein when a sufficient force is applied to the second additional yarn to cause the second additional yarn to break the warp knitted fabric is thereby permitted to stretch in the transverse direction.

13. An inflatable air belt including a cover, the cover comprising:
-
a knitting yarn configured into a warp knitted fabric;
a first additional yarn inserted into the fabric in a position to prevent the fabric from stretching a longitudinal direction;
a second additional yarn inserted into the fabric in a position to prevent the fabric from stretching in a transverse direction; and
wherein the cover is configured so that when the air belt inflates sufficient force is applied to the second additional yarn to cause the second additional yarn to break thereby allowing the warp knitted fabric to stretch in the transverse direction. - View Dependent Claims (14, 15, 16, 17, 18, 19)
