System and method for reducing vehicle noise
First Claim
1. A system for reducing interior noise in a vehicle, the system comprising:
- an instrument panel having an opening for installation of a storage compartment with an access door, the instrument panel including at least one hinge retainers made of a first material;
the access door for the storage compartment having at least one hinge cooperating with the at least one hinge retainers and pivotally secured thereto via a corresponding hinge pin to allow opening and closing of the access door, the access door and at least one hinge being made of the first material; and
an isolator disposed between at least one side of the at least one hinge and a corresponding side of an associated hinge retainer, the isolator being made of a second material to reduce noise otherwise generated by contact between the hinge and the hinge retainer.

Abstract
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.

10. A method for reducing interior noise associated with an instrument panel having a glovebox door hinge and hinge retainer made of a first material, the hinge rotating relative to the retainer to allow the glovebox door to open and close, the method comprising:
positioning an isolator made of a second material between at least one side of each glovebox door hinge and a corresponding glovebox hinge retainer to reduce noise generated from contact between the hinge and corresponding retainer, wherein the isolator is fixed relative to the instrument panel. - View Dependent Claims (11, 12, 13)

14. A vehicle interior assembly comprising:
-
an instrument panel made of a first material and having an opening for a glovebox, the instrument panel including at least one integrally formed hinge retainer having a hole for receiving a hinge pin to secure a glovebox door; a glovebox surround made of a second material extending into the opening for the glove box and secured to the instrument panel, the surround having a cut-out corresponding to each integrally formed hinge retainer so that the hinge retainer projects through the cut-out when the surround is secured to the instrument panel, the surround including at least one integrally formed isolator extending at least partially along at least one side of each hinge retainer; and a glovebox door having at least one hinge cooperating with the at least one hinge retainer and isolator to pivotally secure the glovebox door with a hinge pin that extends through the hinge, isolator, and hinge retainer. - View Dependent Claims (15, 16, 17)
