<P>PROBLEM TO BE SOLVED: To securely develop cells between a head part of an occupant and a side door glass for a short time without additionally requiring surplus means. <P>SOLUTION: This curtain airbag device 10 is provided with an inflator 11 and the plurality of cells 12a to 12d to which high pressure gas blown out from the inflator 11 is supplied via gas inflow ports 13a of a duct part 13 and which are developed and expanded between the head part H of the occupant M and an inside face in a cabin, The gas inflow ports 13a are not installed in the upper position corresponding to the head part H, but are installed the upper positions forward and rearward the head part H. All of the plurality of cells 12a to 12d are not directly communicated with the gas inflow ports 13a. The cell 12b positioned in the side direction of the head part H is communicated with a vertically intermediate part of the cell 12a communicated with the gas inflow port 13a in the upper position forward the head part H, and is expanded and developed from this communication position 12e to a space between the head part H and the inside face of the cabin. Therefore, the cell passes through the side direction of the head part H in which the expansion space of the cell becomes narrow, and the head part H can be securely protected. <P>COPYRIGHT: (C)2007,JPO&INPIT |
