An air bag module (10) includes a housing (12). An air bag (22) is folded and stored in the housing (12). A retaining ring (30) secures the air bag (22) to the housing (12). The retaining ring (30) includes two relatively movable U-shaped members (152, 154). Assembly tabs (210, 212, 252, 254) on the retaining ring members (152, 154) are gripped to move the retaining ring (30), in a collapsed condition, in one direction (32) through a deployment opening (150) into the housing (12). The retaining ring (30) is then expanded and moved in an opposite direction (34) to interlock with the housing (12).

Cette invention concerne un module de protection active gonflable (10) à coussin pneumatique (22) replié dans un logement (12). Une bague de retenue (30) sert à assujettir le coussin pneumatique (22) dans le logement (12). La bague de retenue (30) comprend deux éléments en U (152, 154) mobiles l'un par rapport à l'autre. Des pattes de montage (210, 212, 252, 254) sur les éléments en U (152, 154) de la bague de retenue sont comprimées l'une vers l'autre pour insérer la bague (30) ainsi repliée dans le logement (12) par l'ouverture de déploiement (150) en la poussant dans la direction (32). Une fois à l'intérieur du logement (12), la bague se détend et on la déplace dans la direction opposée (34) pour qu'elle se cale dans le logement.
