In order to provide an occupant-leg protection device having a knee bag that is extremely quickly deployed in front of an occupant's leg even when the output of a gas generator is low, and that ensures a large thickness after inflation, a main chamber is formed by sewing a front panel (26) and a rear panel (28) together, and the interior thereof is partitioned into small chambers (1, 2, 3, 4) by partition panels. A surface panel (30) is sewn to the front side of the front panel (26), and an auxiliary chamber (5) is formed therebetween. When a gas generator (20) is actuated to generate gas, in a knee bag (18), the first chamber (1) is first inflated, and the second chamber (2), the third chamber (3), and the fourth chamber (4) are inflated sequentially. When the third chamber (3) and the fourth chamber (4) are inflated more than a certain extent, gas flows from the third chamber (3) and the fourth chamber (4) into the auxiliary chamber (5) through openings (56) and (58), and the auxiliary chamber (5) is inflated while the surface panel (30) bulges out from the front panel (26) toward an occupant. <IMAGE> |
