Patent ID: 7438314

Claim:
A gas generator device used in automobile safety to inflate an airbag ( 3 ), comprising at least one gas source for inflating the airbag ( 3 ) and at least one gas outlet orifice ( 6 , 106 , 206 ), called the first orifice, for gas to flow out into the airbag ( 3 ), comprising a first portion comprising the gas source, a second portion comprising a side wall ( 2 , 102 , 202 ) through which other gas outlet orifices ( 7 , 107 , 207 ), called second orifices are formed and a flow guide for making the gas pass exclusively through the second orifices ( 7 , 107 , 207 ) when the device is initiated, although not in service, the second orifices ( 7 , 107 , 207 ) being separate from the first orifice ( 6 , 106 , 206 ) and distributed over the side wall ( 2 , 102 , 202 ) of the device so as to render it with a neutral thrust configuration in which forces resulting from the gas outflow through these second orifices are canceled out, when it is initiated, although not in service, the device further comprising a closing mechanism that closes off the second orifices when the device is in service, so that when the device is initiated the gas passes via the first outlet orifice ( 6 , 106 , 206 ).
