Referring to
Alternatively, portions 12, 14, and 16, may be formed as a single unitary body. In some embodiments, it may be desirable to provide a headliner having a substrate and a cover formed as a laminate or other composite. In other embodiments, the headliner, or one or more portions thereof, may comprise a single layer assembly. Portions 12, 14, and 16 are shown as configured to extend along a longitudinal axis of the vehicle in the direction of vehicle travel. Alternatively, the portions may be arranged laterally or non-orthogonally to the longitudinal axis of the vehicle.
Referring to
The material used to form the cover of the middle portion 12 and side portion 14 and/or 16 of the trim panel may be any one of a number of thermal setting or thermal forming materials. Such materials include polymers selected from the group consisting of polyethylene teraphthalate (“PET”), polypropylene, and derivatives and mixtures thereof. Alternatively, other suitable materials may be used as well. For example, any of a variety of biodegradable and/or recyclable materials may be used. The materials may be provided with a variety of surface finishes. For example, the material may have a brushed appearance. Alternatively, the material may have a flat or simulated finish or have some other textured finish.
For reference purposes, the longitudinal axis 42 of headliner 10 is illustrated in
Referring to
Portions A and B may be individually covered with a polymeric cover. Alternatively, portions A and B may be covered with another material such as a non-woven fabric, woven fabric, polyvinylchloride (“PVC”), leather, or other suitable material. When an uncovered substrate is used in the headliner, the surface of the uncovered substrate may be provided with a textured finish or a decorative pattern in the surface.
Referring to
In another embodiment, a single cover portion may be used (i.e., a co-extruded material having two color portions A and B). Such a co-extruded material may include a boundary region between portion A and portion B where the colors bleed and/or otherwise mix together. In order to provide a clean boundary between the two color regions for a headliner type trim panel, the boundary region may be disposed within the channel, ditch joint, or other structure in the substrate. This allows for concealment of the boundary region which may include an area where colors have bled together. The channel may be formed during the extrusion process, i.e., by selecting a die having a cross-section configured to provide the channel. Alternatively, the channel may be formed by bending or warping a flat panel such that the boundary region is disposed within a channel or ditch. Headliner 10 may also be manufactured by injection molding processes to form portions 12, 14, and 16. In other embodiments, the trim panel may be formed by compression molding.
Headliner 10 may be configured to accommodate a vehicle accessory, such as a power and/or communication system including lighting, compass systems, telematics systems, integrated transceivers, and other such devices and systems. Headliner 10 may also accommodate other devices including visors, air bags, grab handles, and other devices. Headliner 10 may be configured to receive such devices by use of any suitable attachment method, such as threaded fasteners and back brackets or clips, adhesive (e.g. hot-melt glue, etc.), Christmas tree type fasteners or any other suitable method. Appropriate sized and positioned openings 20 in the trim panel are provided to receive the various types of vehicle accessories. The openings 20 can be formed during the manufacturing process of the trim panel or cut out after the trim panel is formed.
For purposes of this disclosure, the term “coupled” means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components, or the two components and any additional member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature
The construction and arrangement of the elements of the trim panel system and apparatus as shown in the exemplary embodiments is illustrative only. Although only a few embodiments of trim panels have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited herein. For example, elements shown as integrally formed may be constructed of multiple parts or elements, the position of elements may be reversed or otherwise varied, and the nature or number of discrete elements or positions may be altered or varied. It should be noted that the elements and/or assemblies of the trim panel may be constructed from any of a wide variety of materials that provide sufficient strength or durability, including any of a wide variety of moldable plastic materials (such as high-impact plastic) in any of a wide variety of colors, textures and combinations. Further, the trim panel may be configured to interface with a wide variety of other vehicle accessories. Other substitutions, modifications, changes and omissions may be made in the design of the exemplary embodiments without departing from the scope of the claims.
This application claims priority to U.S. Provisional Application No. 60/796,793, filed May 02, 2006, which is incorporated herein by reference.
