Abstract
Abstract A fiberglass headliner with integrally reinforced roof bows and roof rail for improved structural rigidity. Selected areas of a resin bonded fiberglass headliner are infiltrated and saturated with a suitable liquid thermosetting resin to a predetermined depth and width. The spaces between glass fibers in a resin bonded fiberglass panel are filled with this additional resin to form hardened and rigid sections when cured in a subsequent compression molding process. These hardened areas of resin saturation provide structural rigidity to partially support a vehicle roof panel and to temporarily carry various roof mounted accessories attached in a subassembly process to form a headliner module.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
An automotive headliner panel of molded fiberglass and resin having integral reinforcing roof bows and roof rails comprising, a network of resin bonded glass fibers that defines the panel wherein there are spaces between fibers such that the panel is air permeable, a plurality of integral roof bows extending transversely of the panel between the edges thereof, a roof rail extending along the edges of the panel and connecting the roof bows, said reinforcing roof bows and roof rail being formed by saturating selected localized areas of the resin bonded fibrous network with additional resin to a predetermined depth and width and curing the additional resin.
Claim 2
Dependent Claim
106 words
An automotive headliner panel of molded fiberglass and resin having integral reinforcing roof bows and roof rails comprising, a network of resin bonded glass fibers that defines the panel wherein there are spaces between fibers such that the panel is air permeable, a plurality of integral roof bows extending transversely of the panel between the edges thereof, a roof rail extending along the edges of the panel and connecting the roof bows, said reinforcing roof bows and roof rail being formed by saturating selected localized areas of the resin bonded fibrous network with additional resin to a predetermined depth and width and curing the additional resin.
Claim 3
Dependent Claim
129 words
An automotive headliner module including a headliner panel of molded fiberglass and resin having integral reinforcing roof bows and roof rails of sufficient rigidity to temporarily support roof panel mounted accessories comprising, in combination, a panel formed by compression molding a mat of resin coated glass fibers, a plurality of integral roof bows extending transversely of the panel between the edges thereof, a roof rail extending along the edges of the panel and connecting the roof bows, said reinforcing roof bows and rails being formed by saturating localized areas of the fibrous mat with resin to a predetermined depth and width and curing the saturated localized areas when the resin coating on the fibers is cured, and accessories mounted to the roof panel at the reinforcing bows and rail.
Claim 4
Dependent Claim
129 words
An automotive headliner module including a headliner panel of molded fiberglass and resin having integral reinforcing roof bows and roof rails of sufficient rigidity to temporarily support roof panel mounted accessories comprising, in combination, a panel formed by compression molding a mat of resin coated glass fibers, a plurality of integral roof bows extending transversely of the panel between the edges thereof, a roof rail extending along the edges of the panel and connecting the roof bows, said reinforcing roof bows and rails being formed by saturating localized areas of the fibrous mat with resin to a predetermined depth and width and curing the saturated localized areas when the resin coating on the fibers is cured, and accessories mounted to the roof panel at the reinforcing bows and rail.
Claim 5
Dependent Claim
140 words
In combination with a vehicle having a roof panel and a headliner panel, a headliner located in adjacent reinforcing relationship to the roof panel comprising, an air permeable network of resin bonded glass fibers, said panel having a first surface facing the roof panel and a second surface facing the interior of the vehicle, a plurality of integral reinforcing roof bows extending transversely of the panel between the opposite edges thereof, a roof rail extending along each such edge of the panel and integrally connected to the roof bows, said reinforcing roof bows and roof rail being generally of a rectangular cross-sectional shape projeting inwardly from the first surface towarda but not to the second surface of the headliner panel, said reinforcing roof bows and roof rail being formed of hardened resin filling the spaces between resin bonded glass fibers.
Claim 6
Dependent Claim
140 words
