Abstract

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.
