Abstract: A method of folding a side gas bag in a packet form having a gas bag consisting of a substantially rectangular fabric section having rounded corners, a connecting plate for connecting to a gas generator and having fastening bolts projecting through the fabric section includes the steps of folding the fabric section along a first fold edge to an approximately square shape with free edges; arranging the free edges one over the other; and connecting the free edges with each other to form the closed bag. During the folding, a free space i8s formed between two adjacent layers of the fabric sections for the insertion of a fold rule. Thereafter, the free space is widened by means of a fold rule and the remaining fabric material is then, by means of further fold rules externally engaging and inserted, folded in on both sides from a center of the free space several times in meandering from in layers parallel to the connecting plate.

Abstract: The invention relates to a gas bag module comprising a gas bag, an outer contour of the gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant with a centric opening as a transition to an indentation in the gas bag. The indentation is formed in that during inflation a center portion of the gas bag wall is prevented from freely moving and is restrained. A closure part is provided which encloses one of the indentation and the opening and engages the gas bag wall. A traction device is provided which is connected with the closure part. The traction device is attached such that due to a deployment of the gas bag a tensile force is exerted on the traction device and the tensile force is passed on to the closure part, and one of the indentation and the opening is at least partly closed.

The depression is formed in that during inflation of the gas bag a center portion of the gas bag wall is prevented from freely moving and is restrained. The gas bag has around the depression a ring-shaped chamber to be filled with gas. At least one limiting strap is provided which engages the gas bag wall at a transition from the front wall to the depression, substantially extends alongside the depression and determines a depth of the depression.

Abstract: The invention relates to a gas bag restraint device, comprising a gas bag module which has a gas bag with a gas bag wall. The gas bag wall has a front wall upon which an occupant to be restrained can impact in a case of restraint and has a depression defined by a ring-shaped gas bag wall portion. The depression is generated in that a center portion of the front wall is attached to the module and is prevented from movement when the gas bag is inflated. Holding means are provided at the ring-shaped gas bag wall portion that keep parts of the ring-shaped gas bag wall portion, which get in contact with each other when the gas bag is inflated, in contact with each other in a fully inflated condition of the gas bag, and at least partly close the depression.

Abstract: The invention relates to a gas bag module comprising a gas bag, an outer contour of the gas bag being defined by a gas bag wall which has a front wall for the impact of an occupant and an indentation starting from the front wall. The indentation is formed in that a center portion of the gas bag wall is prevented from freely moving during inflation and is restrained. The gas bag has a ring-shaped chamber to be filled with gas and extends around the indentation. Arranged in the indentation is at least one limiting strap which extends along the indentation and has an end pointing out of the indentation and, related to an inflated condition of the gas bag, is attached to the gas bag wall at least at the end pointing out of the indentation.

Abstract: The invention relates to a gas bag restraining device comprising a gas bag module which has a gas bag with a front wall upon which an occupant to be restrained can impact in a case of restraint. The front wall has a depression which is produced in that a center portion of the front wall is attached to the module and is prevented from moving when the gas bag is inflated.
