The invention concerns an airbag module for the passenger seat in a motor vehicle. The module is characterized by a cylindrical compressed-gas reservoir (1), a tube (2) that encloses the reservoir (1) and has gas-outlet openings (3) distributed along it, two lateral components (4) that are stamped out of sheetmetal and can be forced together along with the tube (2) by the compressed-gas reservoir (1), and an air sack (5) that is provided with a section enclosing the tube (2), that is secured to the tube (2) by means similar to tensioning straps, and that is folded over the tube (2).

Airbag module for passenger seat

A module for installing a passenger airbag, having a trough-like housing (1). The housing essentially comprises a U-shaped base (2) and two essentially flat ends (3). The module also includes a gas generator (4) and a gas sack (5). The gas sack is folded into the housing over the gas generator, One marginal section (6) of the gas sack (5) is wrapped outward around the edge (7) of the housing (1) all the way around. The marginal section (6) is looped along the base (2) around connecting rods (8). The connecting rods secure the ends (3) to the base (2) and extend within a groove-like inward-opening depression (9) in the base (2). A continuous tensioning band (10) attaches the marginal section (6) of the gas sack (5) to the outside of the housing (1) between the edge (7) of the housing and the connecting rods (8), constituting a force-application attachment.
