Abstract
An airbag housing incorporating a molded bin body adapted to store an airbag cushion. A plurality of molded-in surface ribs projects outwardly away from the exterior of the molded bin body. The molded bin body includes a layer of polymer substrate material disposed in over-molded relation to a layer of laminate material providing enhanced toughness and resistance to embrittlement at low temperatures.
Claims19
An airbag housing comprising:
- a molded bin body adapted to store an airbag cushion, the molded bin body having a bottom and a plurality of sidewalls extending upwardly from the bottom, wherein a plurality of molded-in surface ribs projects downwardly away from the bottom, wherein the molded bin body comprises a layer of polymer substrate material disposed in over-molded relation to a layer of laminate material selected from the group consisting of polymer films, polymer or nonpolymer meshes and polymer fabrics, and wherein the laminate material defines a layer of the molded bin body and wherein the surface ribs do not include the laminate material.
An airbag housing comprising:
- a molded bin body adapted to store an airbag cushion, the bin body having a bottom and a plurality of sidewalls extending upwardly from the bottom, wherein a plurality of molded-in surface ribs projects downwardly away from the bottom, wherein the molded bin body comprises a layer of polymer substrate material disposed in over-molded relation to a layer of laminate material selected from the group consisting of polymer films, polymer meshes and polymer fabrics, and wherein the laminate material defines an exterior surface of the molded bin body and wherein the surface ribs do not include the laminate material, wherein the polymer substrate material is selected from the group consisting of;
- polyamide with glass filler, polypropylene with glass filler, and modified polypropylene substantially devoid of glass filler.
