Abstract
A main chamber is formed of a front panel and a rear panel connected together, and the interior thereof is partitioned into small chambers by partition panels. A surface panel is sewn to the front side of the front panel to form an auxiliary chamber in between. When a gas generator is actuated to generate a gas, the gas flows to the auxiliary chamber through the small chambers, and the auxiliary chamber is inflated while the surface panel bulges out toward an occupant.
