A system and method for reducing or eliminating noise generated in a vehicle by contact between components of similar or identical materials isolate the components using a dissimilar material disposed between the components of similar or identical materials. An isolator made of a second material, such as a thermoplastic polyolefin (TPO) is disposed between a glovebox hinge retainer and glovebox door hinge made of a first material that provides desired structural characteristics for an instrument panel assembly, such as acrylonitrile butadiene styrene (ABS) or polycarbonate/acrylonitrile butadiene styrene (PC/ABS. The glovebox hinge retainer may be integrally formed with the instrument panel with the isolator comprising an integrally formed projection in a glovebox surround that extends between at least one side of the hinge retainer and the glovebox door hinge after installation of the glovebox door.
A combination positionable in an interior of a motor vehicle is disclosed herein. The combination includes an instrument panel having a body extending along a lateral axis between an outboard side and an inboard side. The body has an outwardly-facing surface for display in a passenger compartment of a motor vehicle and an inwardly-facing surface opposite the outwardly-facing surface. The combination also includes a score pattern formed in the inwardly-facing surface and defining three regions. Each region is less than fully surrounded by score lines. The combination also includes an inflatable restraint disposed adjacent the inwardly-facing surface at the score pattern. The inflatable restraint is operable to burst through the body upon engagement and thereby convert the three regions into first and second and third doors in the body. The first door is operable to pivot open along a first axis substantially parallel to the lateral axis and the second and third doors are operable to pivot open along respective second and third axes each being substantially transverse to the lateral axis. The combination also includes a vehicle seat operable for adjustable movement relative to the instrument panel. The vehicle seat and the score pattern are positionable relative to one another such that none of the first and second and third doors contact a head of an out-of-position six-year-old anthropomorphic dummy during testing.
