Description

Technical Field

[0001] The invention relates to a vehicle roof having the features of the preamble of claim 1 . Background Art

[0002] Such a vehicle roof is known in practice, can be used in particular for passenger vehicles, and can be designed in a modular manner so that the vehicle manufacturer can connect it to the vehicle body or vehicle frame as a unit. The vehicle roof comprises a roof frame and a roof outer skin element, the former of which can be regarded as a supporting structure at least in the broadest sense, and the latter of which constitutes at least a part of the visible surface of the vehicle roof arranged on the outer side of the respective vehicle. In the interior, i.e. on the side facing the vehicle interior, the vehicle roof has a roof lining, which forms a visible surface visible from the vehicle interior. For example, the roof outer skin element is formed by an at least partially transparent fixed roof element, which is engaged from below by the roof lining only in its edge region. Alternatively, the roof outer skin element is formed by a cover element of a roof opening system, which can be displaced between a closed position closing the top opening and an open position at least partially opening the top opening. In this case, the roof frame can receive a displacement movement mechanism for the cover element or become part thereof. In addition, as a shielding device, the known vehicle roof is provided with a roller blind device, which is arranged below the transparent top outer skin element. An acoustic seal can be provided between the roller blind arrangement and the roof outer skin element, which is in contact with the roof outer skin element from below via a contact surface and has a positive effect on the low noise level in the vehicle interior and serves as a cover for the roof frame element in the open position of the shielding arrangement. If no shielding arrangement is provided, a circumferential gap exists between the roof lining and the roof outer skin element. Through this gap, visually unattractive areas of the vehicle roof can be seen from the vehicle interior. Summary of the invention

[0003] The object of the present invention is to provide a vehicle roof as mentioned above, which is characterized in that it has a visually attractive appearance on the side facing the vehicle interior.

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

[0005] According to the invention, a vehicle roof is proposed, which comprises a roof frame, a roof outer skin element and a roof inner lining, the roof inner lining forming a visible surface visible from the interior of the vehicle. The gap between the roof outer skin element and the roof inner lining is completely bridged by an acoustic seal, which is in particular made in one piece. The gap between the roof outer skin element and the roof inner lining is closed by the acoustic seal. The acoustic seal thus forms a visible surface that is touchable and / or visible from the interior of the roof or the interior of the vehicle. This results in an aesthetically pleasing appearance in the transition area between the roof inner lining and the roof outer skin element. Due to the acoustic seal designed according to the invention, the roof frame or other roof lower structural elements can be effectively laminated without the need for additional components.

[0006] The roof outer skin element of the vehicle roof according to the invention is in particular constituted by an at least partially transparent fixed roof element, which comprises, for example, a glass pane or a plastic pane, which is arranged rigidly or immovably relative to the vehicle body. Alternatively, the roof outer skin element can also be formed by a cover element of a roof opening system, which can be displaced between a closed position, in which the roof opening is closed by the cover element, and an open position, in which the top opening is at least partially opened. As a transparent surface element, the cover element can comprise a glass pane or a plastic pane.

[0007] In an advantageous embodiment of the vehicle roof according to the invention, the roof outer skin element comprises a molded part, in particular circumferentially foamed or injection-molded, with which the acoustic seal contacts from below. The roof outer skin element can be mounted on the roof frame by means of the molded part, into which the central support bracket or the retaining plate can be molded as an insert.

[0008] In a specific embodiment of the vehicle roof according to the invention, the acoustic seal comprises a first contact area against the roof outer skin element and a second contact area against the roof inner lining. The acoustic seal is thus molded to form two contact areas, each of which is in contact via a contact surface with a corresponding mating element, i.e. a mating element on the roof outer skin element or the roof inner lining. For the vehicle roof according to the invention, the acoustic seal has a contact area in direct contact with the roof inner lining, preferably with an edge surface of an edge fold of the roof inner lining or with a laminated fabric of the roof inner lining.

[0009] In particular, the two contact areas of the acoustic seal are made integrally from the same material, for example from foamed rubber or another elastically deformable material. As a result, there is no transition between the different materials of the acoustic seal on the visible surface accessible from the vehicle interior. This has a positive effect on the appearance of the vehicle roof. For example, the contact area with the roof outer skin element is formed by a tubular part of the acoustic seal, which contacts the roof outer skin element from below, the tubular part being made of foamed rubber. The second contact area of ​​the acoustic seal is located, in particular from above, on the roof lining, which can be solid or made of the material of the tubular part. Such a solid part of the acoustic seal can be considered as an integral extension of the tubular part. Preferably, the second contact area is made directly from a flexible part of the contour of the acoustic seal, the flexible part being made, in particular, from foamed rubber. This means that the acoustic seal can always be in seamless contact with the roof lining and the roof outer skin element, compensates for tolerances and provides a clean finish. It is conceivable that the acoustic seal is in a form-fitting contact state with the top outer skin element and / or the top lining.

[0010] In an advantageous embodiment of the vehicle roof according to the invention, the acoustic seal is attached to the roof frame, preferably via a sealing base engaging with a mating element of the roof frame. The sealing base has a groove in which a rib of the roof frame engages and constitutes the mating element. It is also conceivable that the sealing base forms a rib which engages with the groove of the roof frame.

[0011] In order to prevent noise from being generated due to relative movement of components when the relevant vehicle is running, the contact area of ​​the acoustic seal is preferably provided with a lubricating paint. Thus, squeaking sounds and the like can be effectively offset.

[0012] The vehicle roof according to the invention is preferably not equipped with a mechanical shading system, such as a roller blind system.The acoustic seal may therefore be formed circumferentially and be in contact circumferentially with the roof outer skin element from above and with the roof lining from below.

[0013] Further advantages and advantageous embodiments of the subject matter of the invention can be derived from the description, the drawings and the claims. The invention relates to all combinations of at least two features disclosed in the description, the claims and / or the drawings, i.e. each feature mentioned in the description may itself be part of the claimed subject matter, independently of other features and / or descriptions mentioned in the respective context. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] An exemplary embodiment of a vehicle roof according to the invention is schematically simplified in the drawings and is described in more detail below.

[0015] Figure 1shows a perspective top view of a motor vehicle having a vehicle roof according to the invention;

[0016] Figure 2 Shown along Figure 1 The vehicle top cutout at line II-II; and

[0017] Figure 3 Shown along Figure 1 The top of the vehicle is cut out along the III-III line. DETAILED DESCRIPTION

[0018] The figures show a motor vehicle 10 which is a passenger car and has a vehicle roof 12 which covers a vehicle interior 14. The vehicle roof 12 is provided with a roof opening system 16 which is provided with a cover element 18 which is displaceable between a closed position closing a roof opening 20 and an open position opening the roof opening 20. The cover element 18 is a roof outer skin element which forms a visible surface visible from the outside of the vehicle.

[0019] Furthermore, the vehicle roof 12 comprises a roof frame 22, whose side rails extending in the longitudinal direction of the vehicle form guide rails 24 for a displacement movement mechanism of the cover element 18. The underside of the vehicle roof is provided with a roof lining 26, which forms a visible surface of the vehicle roof 12 visible from the vehicle interior 14. The roof lining 26 has an edge fold 28, which circumferentially follows the roof opening 20 and has an upper edge surface 30 facing the cover element 18.

[0020] The cover element 18 has a window device 32, which is configured as a laminated window and is transparent, and a molded portion 34, which is formed or foamed circumferentially in the edge area of ​​the window device 32, by which the cover element 18 can be connected to the displacement movement mechanism or the top frame 22. The molded portion 34 covers the circumferential edge and the circumferential edge strip of the window device 32 on the lower side.

[0021] In order to bridge the gap between the edge surface 30 of the roof lining 26 and the molded part 34 of the cover element 18 in the closed position of the cover element 18, the vehicle roof 12 has a so-called acoustic seal 36 which circumferentially surrounds the roof opening 20 and abuts against the molded part 34 from below via a first contact area 38 and against the edge surface 30 of the roof lining 26 from above via a second contact area 40. The acoustic seal 36 is attached to the roof frame 22.

[0022] The acoustic seal 36 is formed as a two-component extruded part and has a sealing base 42, which is formed from a first material component made of solid rubber or EPDM. The sealing base 42 serves to attach the acoustic seal 36 to the top frame 22 and has a groove 44, which in particular has an undercut, in which a corresponding molded rib 46 of the top frame 22 engages, preferably in a form-fitting manner. The first contact area 38 of the acoustic seal 36 is formed in the manner of a tubular seal and is made of foamed rubber, which constitutes the second material component of the acoustic seal 36. The foamed rubber extends from the tubular area downwardly to the solid part forming the second contact area 40, so that the visible surface of the acoustic seal 36 accessible from the vehicle interior is completely made of foamed rubber.

[0023] To prevent squeaking or the like during the relative movement between the cover element 18 and the acoustic seal 36 and / or between the top lining 26 and the acoustic seal 36, the contact areas 38, 40 of the acoustic seal are coated with a lubricating lacquer. In particular, the outer surface of the acoustic seal 36 can be completely coated with a lubricating lacquer.
