Abstract:
1. An air bag apparatus for shielding a vehicle occupant in the event of a side crash, said air bag apparatus comprising: an acceleration sensor which detects acceleration in a side direction larger than a predetermined value to generate a detection signal; an inflater which generates a gas in response to said detection signal; and an air bag which is folded initially, and expands with said gas, wherein said air bag comprises a main section having one end which receives gas from said inflater and a protrusion section which is provided attached to and extending outwardly away from a tip portion of said main section such that an inner space of said protrusion section is connected with an inner space of said main section, said tip portion being disposed at an opposite end of the main section from said one end, said protrusion section extending substantially tangentially to the tip portion of said main section in a direction orthogonal to an expansion direction of the air bag and having at least one opening formed therein from which said gas is spouted.
