Description

Technical Field

[0001] The invention relates to a vehicle roof comprising a carrier frame which delimits a frame window which is provided with a plate element. Background Art

[0002] Such a roof is known, for example, from document DE 10 20 21 11 1 972 A1 and comprises a carrier frame which is circumferentially constructed and which is provided with a rear glass fixing element on the one hand and a front cover element on the other hand, which can be adjusted between a closed position in which the roof opening is closed and a release position in which the roof opening is at least partially released by means of a corresponding adjustment kinematic mechanism. The roof must be attached to the vehicle body-in-shell from below, i.e. according to the so-called bottom-load process, and comprises two longitudinal frame legs which are connected to one another via a front frame transverse leg and a rear frame transverse leg. The glass fixing element is rigidly fixed to the carrier frame via a polyurethane molded section. In addition, the roof has a roller blind assembly which forms a roller blind reel which is rotatably supported in the region of the central frame transverse leg. The roller blind assembly constitutes a shading assembly, the roller blind of which can be pulled out below the glass fixing element and the cover element, so that the light incidence through the vehicle roof can be controlled. Summary of the invention

[0003] The object of the invention is to provide a vehicle roof which is designed as a so-called top-load roof, i.e. which can be mounted from above on a vehicle body in shell which comprises fixed panel elements and adjustable cover elements and which is distinguished by a small number of assembly steps.

[0004] This object is achieved according to the invention by a vehicle roof having the features of claim 1 .

[0005] That is, according to the invention, a vehicle roof is proposed, which comprises a one-piece carrier frame, which has a fastening surface on the bottom side, via which the carrier frame can be placed on the roof substructure from above, and which comprises two longitudinal frame legs and three transverse frame legs, which respectively connect the two longitudinal frame legs to each other. The front transverse frame leg and the middle transverse frame leg delimit the first frame window. The middle frame transverse leg and the rear frame transverse leg delimit a second frame window, which is provided with a plate element which is attached to the middle frame transverse leg, the rear frame transverse leg and the two frame longitudinal legs completely around its edge via an injection-molded or foamed molded section, wherein the rear frame transverse leg in a direction facing away from the second frame window and the two frame longitudinal legs in a direction facing away from the second frame window each protrude from the molded section for forming a fastening surface, and the middle frame transverse leg is completely engaged / enclosed from below by the molded section on its underside. The middle frame transverse leg forms a carrier section for a cover seal, which extends in the frame transverse direction and which cooperates with an adjustable cover element by means of which the first frame window can be closed.

[0006] On the one hand, the molded section forms a connecting element between the plate element and the carrier frame. On the other hand, the molded section also forms the underside facing of at least the middle frame transverse leg of the carrier section in a one-piece manner, so that an additional interior panel in the region of the middle frame transverse leg can be omitted when assembling the roof. In other words, the molded section ensures an aesthetic appearance of the roof toward the interior without additional components. Furthermore, the material of the molded section can be selected in such a way that given requirements with regard to interior safety, for example with regard to head impacts, are met. Both functions can be achieved in one production step, namely by forming the molded section.

[0007] In an embodiment of the vehicle roof according to the invention which is preferred, in particular in terms of production technology, the carrier frame is a punched and bent part which is produced in one piece or from a single part and comprises two longitudinal frame legs and three transverse frame legs.

[0008] In an alternative embodiment of the vehicle roof according to the invention, the one-piece carrier frame consists of a plurality of leg elements which are rigidly connected to one another, for example welded to one another, and thus form the one-piece carrier frame.

[0009] The roof can be connected to the vehicle bodyshell according to the top loading process, i.e. from above via a fastening surface of the carrier frame, which in particular forms an adhesive surface, which is designed in a frame-like and circumferential manner and is arranged on the outside relative to the molded section, via which the panel element is attached to the carrier frame. Alternatively or additionally, the roof can also be connected to the roof substructure via a screw connection and / or a riveted connection.

[0010] In a preferred embodiment, the injection-molded or foamed molded section of the vehicle roof according to the invention is formed from a polyurethane material which is formed in a corresponding molding tool into which the support frame and the plate element are inserted.

[0011] In order to further reduce the production cutout, in a preferred embodiment, the vehicle roof according to the invention is designed such that the molded section forms a surrounding frame on the underside of the carrier frame, which surrounds or delimits the second frame window and preferably forms a surrounding visible surface which adjoins the underside of the panel element. The surrounding frame thus also includes that region of the molded section which embraces the underside of the central transverse frame leg.

[0012] The vehicle roof according to the invention in particular forms a structural module which can be placed as a structural unit on a roof substructure which can be a component of a vehicle body in white. The vehicle can be a passenger car, but can also be a commercial vehicle.

[0013] Furthermore, the invention also provides a motor vehicle, which comprises a roof substructure, which is preferably a component of the vehicle body-in-white, and a roof of the above-described type, onto which the roof is placed from above. Preferably, the fastening surface of the roof is an adhesive surface, which is circumferentially configured so that the roof is fastened or can be fastened to the roof substructure via a circumferential adhesive bead.

[0014] Further advantages and advantageous configurations of the subject matter of the invention can be found in the description, the drawings and the claims. All combinations of at least two features disclosed in the description, the claims and / or the drawings fall within the scope of the invention, that is, each feature mentioned in the description can be part of the subject matter claimed for protection independently of other features and / or specific solutions mentioned in the corresponding context.

[0019] Figure 4 Show according to Figure 1 Along the roof Figure 1 The section through line C–C in ; and

[0020] Figure 5 Shown is a bottom view of the roof. DETAILED DESCRIPTION

[0021] exist Figure 1 1 shows the roof region of a motor vehicle 10 which is designed as a passenger car and is provided with a roof 12 which is placed as a modular structural unit on a vehicle body 14 and which essentially comprises longitudinal roof beams 16 which extend in the longitudinal direction of the vehicle and laterally delimit the roof 12. The longitudinal roof beams 16 are part of the roof substructure.

[0022] according to Figures 2 to 5 The roof 12 shown in more detail comprises a carrier frame 18 which forms the interface of the roof 12 with the vehicle body 14 or the roof substructure and which is a punched and bent part manufactured in one piece and which comprises two longitudinal frame legs 20 extending in the longitudinal direction of the vehicle, a front transverse frame leg 22, a middle transverse frame leg 24 and a rear transverse frame leg 26. The three transverse frame legs 22, 24 and 26 each connect two longitudinal frame legs 20 to one another.

[0023] The front transverse frame leg 22, the middle transverse frame leg 24 and the rear transverse frame leg 26 delimit a first front frame window 28 which can be adjusted by means of an adjustable cover element 30 between a closed position, which closes the frame window 28, and an open position, which at least partially releases the frame window 28, by means of a suitable adjustment kinematic mechanism. In other words, the frame window 28 forms a releasable roof opening.

[0024] Furthermore, a second rear frame window 32 is formed by the carrier frame 18, which is bounded at the front by the central frame transverse leg 24, at the rear by the rear frame transverse leg 26 and on both sides by one of the frame longitudinal legs 20. The second or rear frame window 32 is provided with a plate element 34 which is designed as a glass fixing element, but can alternatively also be a fixing element made of a transparent plastic plate.

[0025] In the region of the second frame window 32, the carrier frame 18 is provided with a molded section 36 which is formed from a foamed polyurethane material and which completely surrounds the plate element 34 attached to the carrier frame 18, i.e. to the two longitudinal frame legs 20, the middle frame transverse leg 24 and the rear frame transverse leg 26. As can be seen from the figures, during production the carrier frame 18 in a broad sense constitutes an inserted part of the molded section 36, the attachment to which is configured in such a way that the two longitudinal frame legs 20 are attached according to the molded section 36. Figure 3 The type shown projects from the molded section 36 in the vehicle transverse direction in the direction away from the second frame window 32, and the rear frame transverse leg 26 is aligned with the Figure 3 In a manner similar to the type shown, the molded section 36 projects in the longitudinal direction of the vehicle in a direction away from the second frame window 32, and the central frame transverse leg 24 is configured in a strip-shaped area extending in the transverse direction of the vehicle as a carrier section 38, which has no molded section 36, i.e. no polyurethane material, on its upper side and which carries a cover seal 40 which cooperates with the cover element 30 in the closed position of the cover element.

[0026] The molded section 36 completely covers or engages from below the underside of the central frame transverse leg 24 and forms a surrounding frame on the underside of the carrier frame 18, which surrounding frame is formed from a polyurethane material and circumferentially delimits or surrounds the second frame window 32. The molded section 36 thus has a surrounding visible surface facing the vehicle interior in the region of the second frame window 32, which adjoins the underside of the panel element 34 and can adjoin further ceiling elements in the region of the two frame longitudinal legs 20 and in the region of the rear frame transverse leg 26.

[0027] Especially from the attached Figures 3 to 5 As can be seen in FIG. 1 , the support frame 18 has on its underside a circumferential fastening surface 42 , via which the roof 12 can be fastened to the vehicle body shell 14 by means of a circumferential glue bead 44 .
