A METHOD OF ASSEMBLING AN AIRBAG, AND AN AIRBAG

摘要

A method of assembling an air-bag comprises the steps of taking a gas-flow duct (20) which is to be located within a gas-flow passage (16) of an air-bag (1), and applying a hot-melt adhesive (21) to one or more locations on the exterior of the gas-flow duct. The hot-melt adhesive is permitted to cool to a state in which it is substantially solid and exhibits little or no tack. The gas flow duct (20) may then be inserted into the gas-flow passage without affecting the adhesive in any way. Subsequently heat is applied so the hot-melt adhesive at least partially melts. The adhesive then adheres the gas-flow duct (20) to that part of the air-bag (1) defining the gas-flow passage (16). The hot-melt adhesive may cure over a period of time to form a substantially cross-linked adhesive.
