The cushion includes a protective cushion element and outer shell fabrics superposed on both outer surfaces of the protective cushion element. The cushion element includes a cabin-side base fabric and a window-side base fabric that are sewn together by sewing yarns after bonded to each other by adhesive. The outer shell fabrics are bonded to the protective cushion element by adhesive. The adhesive is applied to the outer surfaces of the protective cushion element the joint wherein the base fabrics are sewn together.

An airbag system includes an airbag, and the airbag includes an airbag body having a passenger-side wall portion that is arranged at a passenger side when having completed deploying and inflating, and a slip cloth that is disposed at an outer surface side of the passenger-side wall portion. The slip cloth formed in a loop shape an axial direction of which is in a left and right direction includes: a front panel portion arranged at a passenger side; an upper back panel portion extending downward from an upper end of the front panel portion; and a lower back panel portion extending upward from a lower end of the front panel portion, and a lower end of the upper back panel portion and an upper end of the lower back panel portion are mutually approximated, and joined to the passenger-side wall portion.

An airbag has a configuration in which the lower edge of the inflation shielding section is positioned lower than a belt line that is composed of the lower edge of the window at the time of the full inflation. The airbag is roll-folded such that the lower edge side thereof is wound toward the exterior side after the lower edge side thereof is folded to the exterior side, and is folded such that the lower edge-side end at the time of the full inflation is positioned on the outermost circumferential side of a roll-folding portion. The airbag is folded such that the lower edge-sided end is disposed in a region where, when the roll-folding is released during deployment and inflation, the lower edge-side end does not follow the inner circumferential portion of the roll-folding portion that is deployed on the inner circumferential side of the lower edge-side end, but is disposed at a position of the interior side of the inner circumferential portion.

A retainer and an inflator are disposed inside the airbag. The retainer includes a mounting base section, a holding section which extends from the mounting base section and receives and holds an inflator therein, and a second mounting means which protrudes from the mounting base perpendicularly. The inflator includes a cylindrical body provided with a gas release section and, a first mounting means protruding from a region of the body disposed outside the airbag. The retainer further includes a storing dent section which receives the first mounting means of the inflator so as to conform an orientation of the first means to that of the second mounting means and, a pressing section disposed proximate the storing dent section. The pressing section is brought into close contact with a circumferential area of the body of the inflator when the first mounting means of the inflator is secured to a vehicle body.

A front pillar trim mounting structure has a front pillar (10), a front pillar trim (30), an airbag (60), and an assist grip (70). The front pillar is provided in the front portion of a vehicle. The front pillar trim (30) covers the front pillar (10) from the inner side of the vehicle. The airbag (60) is located between the front pillar (10) and the front pillar trim (30).
