Abstract
An apparatus (10) comprises an inflatable vehicle occupant protection device (14) having internal surfaces (48). The apparatus (10) also comprises an inflator (20) for directing gas (104) into the inflatable device (14) to inflate the inflatable device. The inflator (20) simultaneously directs a coating material (102) into the inflatable device to coat the internal surfaces (48) of the inflatable device (14) to decrease the permeability of the inflatable device to the gas.

An apparatus comprising:
- an inflatable vehicle occupant protection device having internal surfaces, said inflatable device when inflated helping to protect an occupant of a vehicle;
- and
- an inflator for directing gas into said inflatable device to inflate said inflatable device and for simultaneously directing a coating material into said inflatable device to coat said internal surfaces of said inflatable device to decrease the permeability of said inflatable device to said gas.
A method of inflating an inflatable vehicle occupant protection device, said method comprising the steps of:
- providing an inflatable vehicle occupant protection device having internal surfaces, the inflatable device when inflated helping to protect an occupant of a vehicle;
- providing an inflator for inflating the inflatable device;
- directing gas from the inflator into the inflatable device to inflate the inflatable device;
- and
- directing a coating material from the inflator into the inflatable device to coat the internal surfaces of the inflatable device to decrease the permeability of the inflatable device to the gas;
