1. A vehicle airbag restraint system comprising:
- an inflator for providing inflation gas; and
an airbag having an excursion restrictor for controlling the shape of said airbag during deployment of said airbag by said inflation gas from said inflator, said inflation gas passing from said inflator to said airbag by way of a inflation aperture in said airbag which is coordinated with said inflator, said excursion restrictor being a localized adhesive deposited between and joining a front member and a rear member of said airbag, an adhesive bond being created between said adhesive and said front member and said rear member, said excursion restrictor retaining said front member and said rear member in proximity to one another until a predetermined threshold pressure of said inflation gas within said airbag is obtained and thereafter failing to join said front member and said rear member in a controlled manner.

Abstract
A vehicle restraint system having an inflator for providing inflation gas and an airbag. The airbag having excursion restrictors made of localized adhesive deposited between and joining a front and a rear member of the airbag. The excursion restrictors retain portions of the front and rear members in proximity to one another until a predetermined threshold pressure is obtained. Thereafter, the adhesive of the excursion restrictor fails in a controlled fashion and the airbag is allowed to fully inflate.

10. A vehicle airbag restraint system having an airbag and an inflator, the inflator providing inflation gas to the airbag when a signal is received from a sensor positioned on the vehicle which indicates a collision, said airbag comprising:
an airbag having an excursion restrictor for controlling the shape of said airbag during deployment of said airbag by said inflation gas from said inflator, said inflation gas passing from said inflator to said airbag by way of a inflation aperture in said airbag which is coordinated with said inflator, said excursion restrictor being a discreetly positioned localized adhesive deposited between and joining a front member and a rear member of said airbag, adhesive bonds being created between said adhesive and said front member and said rear member, said excursion restrictor retaining said front member and said rear member in proximity to one another until a predetermined threshold pressure of said inflation gas within said airbag is obtained and thereafter failing to join said front member and said rear member in a controlled manner. - View Dependent Claims (11, 12)
