Airbag with low-volume structure
First Claim
1. A frontal impact airbag with an outer fabric layer and an inner fabric layer, the airbag comprising:
- three inflatable sections consisting of a first section, a second section, and a third section, the second section being in fluid communication with both the first and the third section;
a gas generator in fluid communication with the first section;
an end portion on the third section remote from the second section, the end portion being attached to the first section in an area between the gas generator and the second section, the first, second and third sections forming an enveloping volume defined by the outer fabric layer upon inflation of the airbag and an empty space defined by the inner fabric layer; and
a first port on the first section and a second port on the third section, the first port and the second port being aligned with each other and providing a direct fluid communication between the first section and the third section.

Abstract
A frontal airbag has a first section, a second section, and a third section, the second section being in fluid communication with both the first and the third section. The first, second and third sections form a triangular structure upon inflation of the airbag. A gas generator is attached to the first section and in fluid communication with the first section. An end portion on the third section remote from the second sections attached to the first section in an area between the gas generator and the second section. Two side tethers attached to the first section and to one of the second and third sections or near transitional bend between the second and third section provide resistance against flattening of the airbag after inflation. The first section and the third section are directly attached to each other by a seam, by an adhesive, or by lamination.
