The inflator wrap is provided in the front panel and the rear panel and has both ends that are fixed to both of the front panel and the rear panel.

First claim

What is claimed is:

1. A driver airbag structure comprising:
a front panel;
a rear panel facing the front panel, the rear panel comprising an edge that is coupled to an edge of the front panel; and
an inflator wrap provided in the front panel and the rear panel and having both ends that are fixed to both of the front panel and the rear panel,
wherein:
in an unfolded state, the inflator wrap comprises:
a main body;
an upper end which defines an upper portion of the main body; and
a lower end which defines a lower portion of the main body; and

in a folded state, the upper end and the lower end of the inflator wrap are directly engaged with each other by sewing to form a folded portion.

2. The driver airbag structure of claim 1 , wherein the rear panel further comprises a mouth at a center portion thereof through which gas is supplied when the airbag is deployed.

3. The driver airbag structure of claim 1 , wherein when the inflator wrap is sewed, the inflator wrap is configured to be drawn out from the inside of the rear panel through a mouth provided in the rear panel, an upper end and a lower end of the inflator wrap having a flat shape are engaged with each other by sewing, and the inflator wrap is configured to be insertable back into the rear panel through the mouth.
