An occupant protection apparatus includes an airbag module AM installed in a seat portion (10) of a vehicle seat S. The airbag module AM includes an inflator (61) and an airbag (40). High pressure inflation gas G ejected from the inflator (61) inflates the airbag (40), so that a seat surface (10A) of the seat portion (10) is raised. This inhibits forward movement of the lumbar region Pp of an occupant P, who is seated on the seat portion (10) and restrained to the vehicle seat S by a seat belt apparatus (30). The outer shape of the airbag (40) is formed by an airbag body (41). The airbag body (41) includes a rear inflating portion (48), which is inflated below the upper thighs Pf of the occupant P, and a front inflating portion (47), which is inflated below the lower thighs Pn of the occupant P up to a position above the rear inflating portion (48).
