Airbag and method for manufacturing same

Abstract

[Problem] In order to reduce the leakage of inflation gas from a sewn portion of an airbag, the application of a coating material to the sewn portion has been carried out. There are techniques for applying a coating material from one side or from both sides, but there are problems in that when applying the coating material to the opposite side of the initially applied side, the initially applied coating material adheres to a base or flows away. [Solution] Such problems can be prevented by making the viscosity of a binder applied initially to a sewn portion on one side of a base fabric higher than the viscosity of a binder applied subsequently to the sewn portion on the opposite side of the base fabric.
