Abstract
A vehicle seat with an inflatable air cushion in which an air cushion module comprising the inflatable air cushion and a gas generator for inflating the air cushion is mounted to a hollow member of the seat frame. The gas generator is substantially contained within the seat frame to minimize the packaging space required for the air cushion module. In addition, back pressure release gas from the gas generator is directed into the hollow interior of the frame to avoid the discharge of hot gas directly into the seat foam where the foam may be damaged by the heat.
