  • Method and apparatus for folding an airbag
    Patent number: 6327838
    Abstract: A method for folding an airbag for an airbag module involves straightening the airbag out in the direction of a straightening axis, starting from a gas inlet opening of the airbag. The airbag in the straightened-out state, or during the straightening-out operation, is pushed into a guide sleeve in the direction of the straightening axis. The airbag is then pushed together, and in the method folded, within the guide sleeve in the longitudinal direction thereof, in the direction of the straightening axis. An apparatus for folding an airbag for an airbag module has a straightening ram which, for the purpose of straightening out the airbag, can be pushed into the latter in the direction of a straightening axis by way of a gas inlet opening which has a guide sleeve. The guide sleeve is arranged coaxially with respect to the straightening ram. The straightening ram can be pushed along the straightening axis.
