AI Technical Summary

Problems solved by technology

Unfortunately, manually applied gaskets are not always properly positioned or can fall off anyway, which can result in leakage of liquid foam forming material into and / or around the airbag device
Additionally, the piece cost of the gasket and the cost 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. A multi-shot injection molded 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] The technical field relates generally to interior panels configured as inflatable restraints for motor vehicles, and more particularly to foam-in-place interior panels for motor vehicles with integrated air bag doors and methods for making such interior panels method. Background technique [0002] Motor vehicles typically include an inflatable restraint device having an airbag arrangement with an inflatable airbag positioned within or behind an interior vehicle panel, such as an instrument panel, door panels, seats, and the like. Many interior panels include integrated air bag doors formed into the interior panels that are designed to burst open upon deployment of the air bag. Typically the area of ​​the interior panel surrounding the integrated air bag door is scored or pre-weakened to form seams that facilitate unobstructed air bag deployment, eg, with minimal or no debris. [0003] Foam-in-place (FIP) interior panels are commonly used to provide a...
