Abstract

The trim panel is intended for use in decorating the interior of a motor vehicle and finds particular use as the trim panel for decorating the roof of the interior of a motor vehicle. The trim panel produced by the method of this invention is one which, when installed in a motor vehicle, provides for additional head room within the interior of the vehicle because that portion of the trim panel overlying the area of an occupant's head is depressed inwardly toward the ceiling panel from a position it might otherwise occupy. To make the trim panel, a sheet 10 comprising a formable substrate 12 and a cover sheet 14 is prepared and notches 44 cut from the corners of the formable substrate at the same time as a blank 40 is stamped out of the sheet. The centre portion 50 is subject to a hot or cold die forming operation to bring areas of it out of the plane defined by the blank. The formable substrate may be of cardboard, resin impregnated cardboard, paper board or foam cored board having paper or plastics outer layers. The cover sheet may be of fabric or foam backed vinyl. <IMAGE>

Description

SPECIFICATION Trim panel and method of making the same This invention relates to a trim panel and to a method of making the same, especially to trim panels which are intended for use in decorating the interior of a motor vehicle, such as a passenger car or a truck. The trim panels of the invention find particular use for decorating the roof of the interior of a motor vehicle.
According to the present invention, there is provided a method of making a trim panel which comprises forming a flat trim panel which includes a formable substrate and a cover stock; cutting said flat trim panel so as to form the outline of a trimmed part, said cutting operation also including the cutting out of "V" shape notches through only said formable substrate, and not said cover stock at areas of said trim panel which are to be folded when assembled, said trim panel being foldable between adjacent "V" shaped notches formed in said formable substrate, each of said foldable areas between said "V" shaped notches and the associated edges of said trim panel formed in said cutting step forming planar areas; and die forming said formable substrate in areas other than said planar areas thereof in a direction away from said planar areas whereby said die formed areas are generally shaped away from said planar areas thereby to define a finished trim panel.
The invention also includes a trim panel which comprises: a formable substrate and a cover stock on said formable substrate, said formable substrate and cover stock being cut to define a generally planar article having four corners and an exterior edge therearound, said formable substrate also having "V" shaped notches cut therein generally located at said four corners thereof, said "V" shaped notches having the apex thereof located inwardly of said exterior edge of the trim panel with an open portion of said "V" shaped notches intersecting said exterior edge, said apex of said "V" shaped notches being interconnected by a fold in said formable substrate between adjacent ones of said "V" shaped notches, the areas between said folds and said exterior edge forming planar areas, the area defined within said folds being die formed to form a surface extending out of the plain of said planar areas.
In accordance with the preferred embodiment of this invention, a trim panel includes a formable substrate and a cover stock on the formable substrate. The formable substrate and cover stock are cut to define a generally planar article having four corners and an exterior edge therearound. The formable substrate has "V" shaped notches cut therein generally located at the four corners of the substrate.
The "V" shaped notches have the apex thereof located inwardly of the exterior edge of the trim panel with the open portion of the "V" shaped notches intersecting the previously mentioned exterior edge. The apex of the "V" shaped notches are interconnected by fold line depressions formed in the formable substrate between adjacent ones of the "V" shaped notches. The areas between the fol line depressions and the exterior edge of the trim panel form planar areas. The area defined within the fold line depressions is die formed to form a surface extending out of the plain of the planar areas. When installed in a motor vehicle, the die formed area overlies the head of the occupants of the motor vehicle, but is deformed upwardly toward the outer metal roof panel so as to provide additional head space for the occupants of the motor vehicle.The type of die forming operation, either a cold die forming operation or a hot die forming operation, determines the amount of outward deformation produced in the trim panel. The hot die forming operation produces the greatest amount of deformation.
The trim panel is preferably formed in the following manner. A flat trim panel is formed which includes a formable substrate and a cover stock. The flat trim panel is cut so as to form the outline of a trimmed part. The cutting operation also includes the cutting out of "V" shaped notches through only the formable substrate, and not the cover stock at areas of the trim panel which are to be folded when assembled. The cutting operating also includes the placement of fold lirie indentations between adjacent "V" shaped notches formed in the formable substrate. Each of the areas between the fold lines and the associated edges of the trim panel formed in the cutting step form planar areas.The formable substrate is die formed in area other than the planar areas thereof in a direction away from the planar areas whereby the die formed areas the generally shaped away from the planar areas thereby to define a finished trim panel.
If desired, the plane areas may also be die formed to develop features therein. The type of die forming operation, either a cold die forming operation or a hot die forming operation, determines the amound of outward deformation produced in the trim panel. The hot die forming operation produces the greatest amount of deformation.
A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a view of a flat trim panel.
Figure 2 is a cross section of the flat trim panel of Fig. 1 taken along line 2-2 of Fig. 1 showing the formable substrate and cover stock used to make the trim panel.
Figure 3 is a diagramatical representation of a cutting operation in which the trim panel is cut to a trimmed part and in which "V" shaped notches are placed therein along with fold line indentations.
Figure 4 is an elevation view of the trim panel after the operation of Fig. 3 has been carried out thereon.
Figure 5 is a diagramatical representation of a die forming operation in which area of the trimmed part are die formed. The die forming operation may be a cold die forming operation or a hot die forming operation, or a combination thereof.
Figure 6 is a perspective view of the trim panel after the die forming operation of Fig. 5 has been carried out thereon.
In Fig. 1, there is seen a flat trim panel, generally identified by the numeral 10. As best seen in Fig. 2, the trim panel is formed of a formable substrate, generally identified by the numeral 12, and a cover stock, generally identified by the numeral 1 4. The substrate 1 2 can take the form of many different elements. For example, the substrate may be cardboard, resin impregnated carboard, paper board, foam core board, which is two layers of craft paper with an inner expanded layer of polystyrene, or a foam core board in which two layers of plastic are held together by an inner layer of expanded polystyrene. The cover stock may be a fabric material or it may be a vinyl material, and it can be a fabric or a vinyl material with foam located therebehind of any desired thickness.
In accordance with the teachings of the preferred embodiment, the formable substrate 1 2 is made up of two layers of cardboard 16-16 separated by expanded polystyrene 18. The portion of the cardboard 16-16 not in contact with the polystyrene foam can be treated with a barrier material, such as a thin coat of polyethelene, in order to prohibit the movement of moisture through the board.
In accordance with the preferred embodiment of this invention, the cover stock 14 includes a cloth outer fabric 20 which in turn has an inner surface thereof bonded to a polyethelene foam 22 in a flame bonding operation. The polyethelene foam 22 is attached to one face of the cardboard material 1 6 in a separate flame bonding operation.
Likewise, the bond may be formed from an adhesive material applied from either a hot melt application or cold application at room temperature.
In accordance with the teachings of this invention, the flat trim panel 10 is cut so as to form the outline of a trimmed part. The cutting takes place by placing the flat trim panel 10 on a suitable cutting table 24, as shown in Fig. 3. The cutting is accomplished by bringing a cutting member, generally identified by the numeral 26, into contact with the flat trim panel. The cutting device includes a steel die rule cutter 28 which cuts the outline of the desired trimmed part in a standard manner. The cutting device 26 also includes "V" shaped cutters, one identified by the numeral 30 in Fig. 3, which cut "V" shaped notches through only the formable substrate, and not the cover stock 14.The cutting device 26 also includes fold line indentation placement devices 32, one shown in Fig. 3, which place a fold line in the formable substrate 1 2 between the apex of each adjacent "V" shaped notch.
Reference is made to Fig. 4 which shows a trimmed trim panel, generally identified by the numeral 40. An exterior edge 42 is formed around the entire perimeter of the trimmed trim panel 40 in the cutting operation, shown in Fig. 3. The trimmed trim panel 40 also has four "V" shaped notches 44-44 cut therein in the cutting operation. These "V" shaped notches are cut as aforesaid only through the formable substrate 12, and not through the cover stock 14. As is easily seen in Fig. 4, the "V" shaped notches 44-44 are formed so that the apex of each such notch is located inwardly of the exterior edge 42 of the trimmed trim panel 40. An open portion of each of the "V" shaped notches intersects the exterior edge 42 of the trimmed trim panel.
A plurality of fold line indentations 46-46 interconnect the apex of the "V" shaped notches 44-44. These fold line indentations 46-46 are placed in the formable substrate by the fold line indentation placement device 32, only one shown in Fig. 3. The fold line indentations provide a means for folding the area defined between a pair of associated "V" shaped notches, a fold line indentation 46 and an exterior edge 42. Generally, a planar area 48-48 is formed by each area bounded by a pair of "V" shaped notches, a fold line indentation 46, and the exterior edge 42 of the trimmed trim panel 40. The planar areas 48 are folded upwardly, as viewed in Fig. 4, until the associated edges of the "V" shaped notches 44-44 come in contact with one another to define the final folded position of the planar area.A central area, identified by the numeral 50 in Fig. 4, is formed in the center of the trimmed trim panel 40 as the area within the fold line indentations 46-46.
The trimmed trim panel 40 also has a pair of locating projections 52-52 thereon which have locating openings 54-54 therein.
In accordance with the teachings of the method of this invention, the central area 50 of the trimmed trim panel 40 is die formed so as to form this area in a curved manner generally away from the planar areas 48-48 outwardly, as viewed in Fig. 4. This die forming operation is accomplished by equip ment schematically shown in Fig. 5. The die forming operation may be a cold die forming operation taking place at an ambient temperature or a hot die forming operation taking place at a temperature above an ambient temperature. It is also possible to subject one portion of the central area 50 of the trim panel 40 to a cold die forming operation, while another portion of the central area is subjected to a hot die forming operation. The difference between the two operations is that the material may be formed to a greater dpeth in the hot die forming operation.
The die forming equipment is generally identified by the numeral 56 and includes a lower forming member 58 and an upper forming member 60 closable on the lower forming member 58. The lower forming member 58 has locating pins 62 thereon (only one shown) which enter the locating openings 54 of the locating projection 52-52 in order to locate the trimmed trim panel 40 in proper association with the lower forming member. The lower forming member also has a pair of raised areas 64-64 over which the formable substrate 1 2 of the trimmed trim panel 40 may be molded by suitable recessed areas located on the upper forming member. The upper recessed areas are not shown in the drawings.
The recessed areas on the upper forming member 60 compliment the shape of the raised areas 64-64 so that when the lower forming member and the upper forming member are brought into engagement with one another, the formable substrate 1 2 is formed over the raised areas 64-64 in order to shape the same.
In a cold die forming operation, the trimmed trim panel 40 is placed in the die forming equipment 56 at an ambient temperature for the forming operation. In the cold die forming operation, generally the maximum amount of deformation by the die forming equipment is about one-half inch.
In hot die forming operation, the trimmed trim panel 40 is placed in the die forming equipment 56 at a temperature above ambient. The selected temperature depends on the material to be formed and may be in the range of 100"F to 300"F. In such a hot die forming operation, generally the maximum amount of deformation by the die forming equipment is about two inches.
In accordance with some detailed teachings of this invention, the trimmed trim panel 40 may be heated to the required temperature around the perimeter of the area to be deformed by a heating device located outside the die forming equipment 56. The trimmed trim panel is then placed in the die forming equipment for the die forming operation. As an alternative process, the device for heating the trimmed trim panel may be built into the die forming equipment. In such a case, the trimmed trim panel is first heated in the die forming equipment and then die formed.
As best seen in Fig. 6, a completed trim panel, generally identified by the numeral 70, is shown. In this situation, a pair of die formed depressions 72-72 exist in the finished trim panel. These die formed depressions extend in a curved fashion generally away from the planar areas 48-48. When this trim panel is assembled into a motor vehicle, the die formed portions provide greater head room for the occupants of the motor vehicle. The depth of the die formed portion is controlled, of course, by the type of die forming operation used to form the same.
While particular embodiments of the invention have been illustrated and described, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the invention.
