Benefits of technology
The present invention provides a vehicle door trim panel fastening system that reduces rattling and noise during vehicle operation. The system uses a stake joint with spacers and a mating part with lock ribs that are interposed between the spacers and mushroom heads, which avoids relative movement between the parts. The method of fastening the door trim to the vehicle door involves connecting the mating part to the stake joint, allowing a mushroom head to form around the lock ribs, and avoiding relative movement of the parts. This system and method effectively solves the issue of rattling and noise in vehicle door trim panels during vehicle operation.
Problems solved by technology
However, mating trim panels in this manner allows for rattling of the door trim due to relative movement at the stake joints, which can be an inconvenience during vehicle operation.
Nevertheless, these modifications have only resulted in a partial reduction to the amount of rattling which remains above the desired threshold.

A vehicle door trim panel fastening system is presented herein. The system includes a stake joint and mating part. The stake joint extends from at least a portion of a base panel and has a plurality of spacers. The mating part is joined to at least a portion of a door trim panel and has a plurality of protruding lock ribs. Moreover, the mating part is configured to operatively connect to the stake joint such that the mating part is interposed between the proximal end of each of the plurality of spacers and a mushroom head. The mushroom head is also configured to form around the plurality of lock ribs so as to avoid relative movement of the operatively connected mating part.
Description
INTRODUCTION[0001]For vehicle door trim panel and other interior assemblies, component panels may be installed through the implementation of stake joints that protrude from an installed base panel. However, mating trim panels in this manner allows for rattling of the door trim due to relative movement at the stake joints, which can be an inconvenience during vehicle operation. It is therefore desirable to reduce this trim rattling. The stake joint fastening system presented herein accomplishes such an effort.[0002]In addition, a reduction to door trim rattling has been desired for a quite some time. Previous modifications to the door trim assembly process and panel structure have assisted in rattling reduction. Nevertheless, these modifications have only resulted in a partial reduction to the amount of rattling which remains above the desired threshold. Thus, the stake join system presented herein further assists in achieving a rattling level within the desired threshold.SUMMARY[000...
