6 Claims. (Cl. 296-137) This invention relates to an improved head lining assembly for a vehicle body.

- It is particularly designed as a head lining for a motor vehicle which travels over the road and wherein the roof and head liningof the body are subjected to vibration during such travel.

United States Patent ice ' downward deflection of the roof and to damp out any An object is to provide a head lining assembly which is neat and attractive in appearance and is capable of being quickly and easily installed in position with a minimum of effort.

Another object is the provision of such a head lining wherein the lining'is supported at itsedges by supporting and the lining is bowed upwardly toward the roof and tensioned upwardly to resist any downward pressure of the roof and to damp out vibration thereof.

. It is customary in automobile body trim work to provide an insulation pad or-the like on the underside of the metal roof of the body which pad may serve the purposes of sound insulation and heat insulation. This improved panel assembly is so formed and tensionedupwar dly toward the roof as to directly engage this pad throughout means secured to the opposite side walls of the vehicle vibration thereof.

In shaping the panel assembly to conform with the underside of the roof and particularly through the cove portions thereof the side panels or cove panels are bent on compound curved lines. To facilitate this bending without resulting rupture or breakage of the panel these cove panels are provided with a plurality of beads or corrugations which extend transversely of the panel and which form hinge. lines to facilitate bending of the panel. These beads may be expanded or contracted. Along one longitudinal margin of the panel a bead may be extended or flattened, while along the other longitudinal margin of the panel it may be compacted. This is important in facilitating the accommodation of the cove panel to the curvature demanded.

A meritorious feature is that to augment the resiliency of the cove panels the fiber grain may be extended in the same direction or parallel to the direction of extension of the beads.

This application is a continuation-impart of an application this day filed, Serial No. 569,998, and now abandoned, which is a continuation-in-part of my abandoned application Serial No. 529,243 filed August 18, 1955, and a companion case to my abandoned application Serial No. 529,188 also filed August 18, 1955.

at least the intermediate area of the roof and exert an upward tension thereagainst toward the roof.

In automobile body design the roof normally exhibits a relatively fiat or slightly arcuate area throughout its central portion. Along opposite side walls of the body there are cove portions wherein the roof blends into the 1 I side walls. This is generally true along not only the opposite longitudinal side walls but the front and rear walls. These cove portions present areas which exhibit compound curves or arcs and wherein a panel to conform generally thereto must be bent to exhibit such .a

compound curve. .In the instant construction the head lining assembly comprises panels which extend fore and aft of the. vehicle. These panels are held in alignment by matching and supporting strips extending between and embracing adjacent margins of adjacent panels. strips and the panels'constitute the head lining assembly. These panels and strips are flexible, self-supporting, and preferably resilient.

'When the assembly is secured within the body opposite ends of the supporting and matching strips are secured to supporting means provided within the body at the front and at the rear and so secured that the strips are bowed upwardly and the panels held by the strips are bowed upwardly toward the roof. The assembly includes an intermediate panel which extends generally along the longitudinal center line of the body and two side panels or cove panels disposed on either side of this intermediate panel. This intermediate panel and the two cove panels are held in alignment by the matching and supporting strips. cove panels are .supported upon panel supporting means extending along opposite sides of the body below the roof. These cove panels are so supported that their opposite longitudinal margins exert a pressure against The .in a motor vehicle embodying the invention;

This invention is illustrated as embodied in an automobile body having a roof portion 20, a front windshield portion 22 and a rear window portion 24. The roof is commonly formed of metal. The body construction other than as described herein is conventional in motor vehicles. Opposite ends of the roof merge into'a front 23.8 79', lab.

wall. definedv by the windshield and a. rear wallv defined.

by the rear window. Opposite sides of the roof merge into side walls which are commonly provided with doors and windows. The metal roof at the frontmay be provided with a boxlikeframe portion 26 shown in Figs. 4, and 8. It; may be provided at the rear with a boxlike frame: portion 28 shown in. Figs; 4 and 11. At the side the roof. may be shaped and reinforced to' provide. a 'hoxlike side: frame: 30,. as. shown in: Figs; and 13. The side frame 30 may have a. series of higs; 32. struck there from as shown in Fig. 5 to serve as a head lining supportingmeans and a molding plate 34 may be provided associated with the boxlike frame 30. as shown in. Fig.1 5.

The head lining assembly itself comprises a plurality of flexible panel. sections which. extend fore and aft of the vehicle under the vehicle roof. These panel sections have associated therewith panel supporting and matching strips which. are also flexible and preferably resilient. In Figs. 1, 2 and 3 the assembly is. illustrated as comprising, a center line panel 36. and two side panels 38. The matching and retaining strips are indicated generally by the numeral as shown. in. Figs. 1, 2 and 3. The construction of this application is generally similar to the construction of my co-pending application referred to hereinabove in that each comprises an assembly of panels and supporting. and. retaining strips so associated to gether that the assembly is bowed upwardly toward the underside of the'roof and held bowed and tensioned upwardly toward the roof and against the: underside of the roof. The instant construction differs from the construction of the co-pending application, supra, in that the panel assembly is tensioned upwardly toward the roof and. against the. roof both fore and" aft and transversely. It also differs in the: provision of the particular side panel or cove: panel sections and the manner in which they are associated. with an intermediate panel disposed. therebetween, all as' herein described.

In the several figures of. the drawings the underside of metal roof 20 is shown as" having adhesively secured thereto an insulation pad 42 of suitable fibrous wadding such; as fibergla's or the: like. This serves as sound and heat insulating insulation.

The intermediate or central panel 36 may be formed of Masonite or the like provided in the form of a relatively dense normally resilient thin hard board which may be provided; with a multiplicity of perforations as shown to permit passage of sound waves therethrough to the. insulation pad 42. This perforated Masonite panel may have a suitable lacquer or other finish coat applied to its undersurface; As shown in Figs; 1, 2', 3 and 9 such panel is of substantially uniform width and extends fore and aft along'the center line. on the underside of the roof. As shown in Fig. 12 such panel maybe of a generally triangular shape having. a greater width at one end than at the other.

Along opposite linear margins of this panel 36 I provide matching and supporting strips identified generally in Figs. 1, 2 and 3-as 40. Each of these strips is. a two piece strip as shown in. Figs. 5 and 7. These strips are the same as those shown. in my said co-pending application. There is a base or male portion of the strip identified in Fig. 7 as 44 and a cap or female portion 46. The base portion is formed generally in cross section somewhat in the fashion of av railway rail. The cap portion has a pair of spring lips 48 which are adapted to be snapped over the head of the rail. The cap portion has a pair of side walls 50 which are adapted to engage panels received over the base portion when the lips 48 of. the cap are snapped over; thehead of the. base portion, all as shown in Fig. 7. This is all more particularly described in the co-pending application.

Opposite ends of the base portion 44 of the strips may be secured by screws 52 or the like to front boxlike frame portion 28 as shown in Fig. 4. These. strips are of such .al'ength that when theends are secured as shown the strips are bowed upwardly toward the underside. of the roof. The strips are preferably of resilient metal or the like so that they are tensioned upwardly against the underside of the roof throughout the longitudinal mid section of the roof. When these strips are secured in position as described and the center panel is placed thereon and the cap strips are secured in their overlying relationship, all as shown in Figs. 5: and. 7, the center panel is secured bowed upwardly against the underside of the. roof and held there by the strips. This center panel of perforated Masonite or the like is, also resilient.

On either side of the center panel 36' the sidev panels 38 form cove panels overlying the cove portions of the roof but spaced therebelow and inwardly therefrom by the dimension of the box frame elements 30, all as shown in Figs. 5 and 13. These side panels are formed of suitable flexible. sheet material. Composition fiberboard may be employed. These panels must be bentv to exhibit a compound curvature because of the shape of the cove portions particularly at their. ends as illustrated in Figs. 2 and 4. The curvatures which must be assumed by opposite margins of these. side panels vary not only from place to place but on. opposite sides.

To facilitate this bending into. more. than one arcuate design the side panels arev provided with a plurality of beads or corrugations 56 which are shown as extending generally transversely of the panels. These beads are deformed out of the plane of the panels. These beads constitute hinge lines along which the panel bends readily. The beads may be flattened permitting expansion.. The beads may be compacted permitting contraction. The beads may expand at one end. and. contract at the opposite endso that. the. curvature: lines can be varied. This is shown in Fig.v 10 where the beads are shown expanded at. one end and contracted at the other,. and are also. shown as variably expanded and contracted.

When the side panels are inserted. in place as shown in. Fig. 5 with one longitudinal margin seated upon the head lining retaining means in. the form of lugs 32 along the side walls of the body and the opposite longitudinal margin of the side panel engaged with the matching and retaining strip as shown in Fig. 7 these panels are bowed transversely as shown in Fig. 5 and exert a pressure through the web portion of the strip against the margin of the center panel 36. The construction is particularly secure and rigid in the sense of exerting a tension upwardly against downward deformation of the roof.

Normal variations in body width which may vary in different bodiesv of the same model up to half an inch or so are taken care of in the bend of these panels and in certain permittted compressibility of the web portion of the supporting and retaining strip as is heretofore more particularly set forth in my application. Serial No. 529,188 filed August 18, 1955.

In order to augment the resiliency of these side panels it has been found desirable in certain embodiments that the grain of the fiber of the board run transversely of the panel board and therefore parallel to the beads. This seems to increase the normalv resiliency of the panel board and serves to improve the. tensioning of the assembly in its upwardly bowing.

It will be noted, that the front and rear margins of the longitudinally extending panels are not directly seated upon head lining retaining means fore and aft, although such. might bev the case. Thev panels are. held. by their gripped engagement by the panel supporting and matching strips and these support the panels: in their fore and aft bowed position. Along the side margins, however, the side panels or cove panelshave their outer longitudinal margins seated as' shown on the side retaining elements. A molding piece 58' may lac-"secured by screws 60 to the boxlike frame 26 ,at. the front .end of .the vehicle and extending across the front over the windshield. A molding 62 may be secured by screws 64 t'o'the boxlike frame section 28 at the rearend of the vehicle which molding extends along over the rear window. Along the sides the molding 34 is shown as overlapping the margins 38 in Fig. 5. In Figxl3 a slightly different type of molding is provided. Such molding is indicated ,at 66 and it is a deformable molding strip which is adapted to be secured to the box frame 30 and to be folded upwardly over the margin of the panel.
