Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
A headliner panel for use with a motor vehicle and for use with an assembly process including part locators for aligning headliner panels during various process steps comprising a contoured molded panel of predetermined thickness at selected locations and configured to the dimensions of the motor vehicle, said panel defining a locator notch extending from one surface of the panel inwardly, said locator panel notch being positioned at a location having sufficient thickness that the locator notch does not extend through the panel, said notch defining a cavity fill area of panel material extending into the locator notch, and said notch serving as an opening for mating with part locators for assuring positive alignment of the panel for subsequent manufacturing operations.
Claim 2
Dependent Claim
121 words
A headliner panel for use with a motor vehicle and for use with an assembly process including part locators for aligning headliner panels during various process steps comprising a contoured molded panel of predetermined thickness at selected locations and configured to the dimensions of the motor vehicle, said panel defining a locator notch extending from one surface of the panel inwardly, said locator panel notch being positioned at a location having sufficient thickness that the locator notch does not extend through the panel, said notch defining a cavity fill area of panel material extending into the locator notch, and said notch serving as an opening for mating with part locators for assuring positive alignment of the panel for subsequent manufacturing operations.
Claim 3
Dependent Claim
33 words
The headliner panel as set forth in claim 1 wherein the locator notch is generally annular in configuration and wherein the cavity fill area projects in the center of the annular locator notch.
Claim 4
Dependent Claim
53 words
The headliner panel as set forth in claim 2 wherein the density of the panel in the cavity fill area is larger than the panel generally and wherein the cavity fill area does not project the entire thickness of the panel such that the cavity fill area is recessed from the panel surface.
Claim 5
Dependent Claim
18 words
The headliner panel as set forth in claim 3 wherein the molded panel defines four spaced-apart locator openings.
Claim 6
Dependent Claim
46 words
The headliner panel as set forth in claim 2 wherein the annular notch defines an entry curve to the panel surface and a fill curve to the cavity fill area, both curves being rounded to facilitate the panel being located on an annular projecting locator device.
