Abstract: An airbag for an airbag module is a section of a seamless continuous tube, at least partly gastight with the free ends of the tube closed and in its inflated state essentially maintains its original volume and its original length. An airbag module includes the airbag and an airbag inflator, which is or can be connected with the airbag. The tubular airbag may be installed in either a seat cushion or seat back of a vehicle seat to act as a barrier to a seat occupant sliding out of the seat when the airbag is deployed.

Abstract: A method and an apparatus for folding an airbag of a vehicle occupant restraining system, having a conveyor means, in which a first portion of the spread-out airbag is moved in order thus to push a second portion of the airbag against an abutment which has at least one abutment surface extending substantially parallel to the direction of movement, so that the second portion of the airbag is laid in folds. In order to obtain a regularly folded airbag in a particularly simple manner, the conveyor means is formed with at least one rotating conveyor element which can move the first portion of the airbag in the direction of the abutment.
