Abstract

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).

Description

technical field [0001] The invention relates to an occupant protection device applied to a vehicle seat. Specifically, the present invention relates to an occupant protection device that inflates an airbag installed in a seat portion of a seat by an inflation fluid (such as inflation gas) to raise the seat surface, thereby preventing the occupant restrained by the seat belt device from Move your waist forward. Background technique [0002] When an impact is applied to a vehicle due to a frontal collision, a "submarine phenomenon" may occur even if an occupant is restrained by a seat belt device. Specifically, the occupant is restrained by the vehicle seat, and when the submarine phenomenon occurs, the occupant's waist is disengaged from the lap belt of the seat belt device, and moves forward in a sinking manner. Various measures have been proposed against this submarine phenomenon. [0003] For example, Japanese Patent Laid-Open No. 2007-168599 discloses an occupant prote...
