<p><P>PROBLEM TO BE SOLVED: To uniformly distribute a gas to a cell on a side near an inflator and a cell on a far side in an occupant restraint device in which a gas feeding tube is arranged inside an upper communication passage of an airbag. <P>SOLUTION: On the gas feeding tube 29 arranged inside the upper communication passage 28 of the airbag 18 and connected to the inflator 33, a distal end opening 29a opened to the distal end and feeding the gas into the upper communication passage 28 is provided, and between a sewing part 24 for dividing the cell 27f positioned below the upper communication passage 28 and the distal end opening 29a, a gas distribution passage 36 for distributing the gas from the distal end opening 29a to the cell 27f is formed. Thereby, the gas jetted from the distal end opening 29a can be also certainly fed to the cell 27f to which the gas is hardly fed. Deployment performance and occupant restraint performance of the airbag 18 can be enhanced by uniformly distributing the gas to all cells 27a-27f. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
