1. A side airbag apparatus, wherein
the side airbag apparatus is employed in a vehicle seat that includes a seat back and a seat belt guide attached to the seat back,
the seat back includes an accommodation portion in a lateral portion on an outer side,
the seat belt guide is attached to the lateral portion at a location above the accommodation portion,
the side airbag apparatus, comprising:
a gas generator that extends along an axis, is installed in an upright state in the accommodation portion, and generates inflation gas in response to an impact force applied to a side wall of a vehicle from a side;
an airbag that is installed in a folded state in the accommodation portion and inflates with the inflation gas supplied from the gas generator so as to deploy and inflate between an occupant seated in the vehicle seat and the side wall with a part of the airbag remaining in the accommodation portion; and
a pressure receiving member arranged rearward of the airbag in the accommodation portion,
the pressure receiving member includes
a main body that includes a pressure receiving surface extending along the axis and receives pressure of the inflation gas in the airbag to produce a reaction force in a direction perpendicular to the pressure receiving surface, and
an upper restricting portion that is located above and adjacent to the main body and includes an upper restricting surface located forward of an imaginary upward extension of the pressure receiving surface, the upper restricting portion restricting upward deployment and inflation of the airbag using the upper restricting surface, and
the upper restricting surface is inclined relative to the axis by a constant angle such that its upper end is farther forward from the axis than its lower end, restricts upward deployment and inflation of the airbag before the airbag reaches the seat belt guide, and causes the airbag to deploy and inflate to a position above the seat belt guide.
