Problems solved by technology

Unfortunately, manually applied gaskets are not always properly positioned or are missing entirely, which results in leakage of liquid foam forming material into and / or around the airbag device
Additionally, the component cost of the gasket and the expense of applying the gasket can be relatively expensive

Abstract

Interior panels having integrated airbag doors for motor vehicles and methods for making such interior panels are provided herein. In one example, an interior panel comprises a substrate having outer and inner surfaces and an opening extending therethrough. An airbag chute-door assembly is mounted to the substrate and comprises a chute wall that at least partially surrounds an interior space. A door flap portion is pivotally connected to the chute wall and at least partially covers the opening. A perimeter flange extends from the chute wall and has a flange section that overlies the outer surface of the substrate. A molded-in lip feature extends from the flange section and contacts the outer surface to form a seal between the flange section and the substrate. A skin covering extends over the substrate and a foam is disposed between the skin covering and the substrate

Description

technical field [0001] TECHNICAL FIELD The field relates generally to structural interior panels for inflatable restraint devices for motor vehicles, and more particularly to foam-in-place interior panels for motor vehicles with integral airbag doors and methods of making such interior panels. Background technique [0002] Motor vehicles often include inflatable restraint devices with airbag arrangements, with inflatable airbags located in or behind interior vehicle panels, such as instrument panels, door panels, seats, and the like. Many interior panels include integral air bag doors formed into the interior panels that are designed to rupture freely after air bag deployment. Typically, the area of ​​the interior panel surrounding the integral airbag door is scored or pre-weakened to form seams that facilitate clean airbag deployment, eg, airbag deployment with little or no rupture. [0003] Foam in place (FIP) interior panels are commonly used to provide a caulk finish to...
