Patent Images
1. A curtain airbag device comprising:
- a curtain airbag having a gas inlet, wherein the curtain airbag is configured to be deployed downward along an inner side surface of a vehicle cabin;
a gas generator configured to supply gas from the gas inlet into the curtain airbag; and
an insertion block that communicates with the gas generator, wherein the insertion block and the gas inlet are clamped with a clamp from the outside of the gas inlet so as to be connected to each other, wherein the gas generator or the insertion block is inserted into the gas inlet, and wherein a seal is disposed on the inner surface of the gas inlet.

Abstract
A curtain airbag device maintains an elevated internal pressure of a curtain airbag for many hours. When an inflator is activated, a curtain airbag is deployed downward along an inner side surface of a vehicle cabin. During the deployment, a duct of the inflator is inserted into a gas inlet of the curtain airbag and is clamped with a clamp such as a band. Elastic adhesives are disposed on grooves in the inner surface of the gas inlet along the ends of a linear connected portion. As a result, the likelihood of gas leakage from the space between the inner surface of the gas inlet and the outer circumference of the duct is reduced.

5. A curtain airbag device comprising:
-
a curtain airbag comprising a gas inlet;
a gas generator configured to supply gas through the gas inlet and into the curtain airbag;
an insertion block that communicates with the gas generator and the curtain airbag; and
a clamp that clamps the insertion block in the gas inlet from the outside of the gas inlet so that the insertion block and an inner surface of the gas inlet are joined, wherein the curtain airbag is configured to be deployed downward along an inner side surface of a vehicle cabin, wherein a seal is disposed on the inner surface of the gas inlet, and wherein the seal is of sufficient strength to maintain an internal pressure of the curtain airbag at an elevated level for at least one hour after deployment of the curtain airbag. - View Dependent Claims (6, 7, 8, 9, 10, 11)
