<P>PROBLEM TO BE SOLVED: To provide an airbag capable of protecting an occupant by proper reaction force corresponding to a state of the occupant, and capable of easily reducing manufacturing cost without receiving influence of an external factor. <P>SOLUTION: This airbag 11 includes a belt 23 inside an airbag body 21. The belt 23 is guided by a guide 22. A vent hole 32 is covered with the belt 23. An intermediate part 41 of the belt 23 pulled from the front and rear, covers and blocks up the bent hole 32 in a state of maximally inflating the airbag body 21, and firmly restricts the occupant B in a state of securing internal pressure of the airbag body 21. When the occupant A abuts on the airbag 11 before maximally inflating the airbag body 21, gas is exhausted from the opened vent hole 32 in a state of loosening the belt 23, and the occupant A is softly restricted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
