1. An airbag module comprising:
- an inflator for generating a gas;
an airbag cushion adapted to be inflated;
a tether coupled to the airbag cushion at both ends and comprising a section formed of a fabric material the section formed of fabric material additionally having an increased friction portion attached thereto; and
a tether holder adapted to contain the section prior to inflation and inhibit twisting of the tether during deployment of the tether when the airbag cushion is inflated; and
wherein the tether holder is coupled to an inner surface of the airbag cushion to allow the tether to be sequentially deployed, and wherein the tether holder is provided on a part of the airbag cushion such that the increased friction portion makes contact with the inner surface of the airbag cushion to increase friction between the tether, the tether holder and the inner surface of the airbag cushion during deployment.

Abstract
A passenger airbag module equipped with an airbag cushion and a tether holder used in a vehicle. The tether holder holds a tether prior to inflating the airbag cushion and inhibits twisting of the tether during deployment of the tether when the airbag cushion is inflated. When the tether is deployed without being twisted or folded, the deployment length of the tether is not reduced. Thus, the airbag is more consistently deployed and inflated.
