Description

TECHNICAL FIELD

[0001] The invention relates to an openable vehicle roof. BACKGROUND

[0002] Such a vehicle roof is known in practice and is in particular a panoramic roof of a passenger car. The panoramic roof has a roof skin which forms a fixed roof portion and surrounds a roof cutout in a frame-like manner. A unit comprising a fixed roof element is accommodated in the roof cutout, the fixed roof element being formed by a flat, transparent glass panel and the roof opening being adjacent to it before and behind the fixed roof element. Furthermore, the unit comprises a roof opening system with a cover element which is movable by means of a displacement kinematics between a closed position in which the roof opening is closed and an open position in which the roof opening is at least partially open. When the cover element is moved from the closed position, it is moved over the fixed roof element. The displacement kinematics comprises inclined levers which are located on either side of a vertical longitudinal center plane and which are moved along a respective lateral edge in a respective guide rail during the opening process. On the inner edge of the roof skin, a circumferential, frame-like weather strip device is provided which forms a transition between the roof skin and the insert or cover element and the fixed roof element of the unit. The area above the guide rail which is arranged between the roof skin and the fixed roof element is sealed by the weather strip device. When the cover element is moved by the respective inclined lever, the weather strip device in this area is deformed and is wider in the vehicle transverse direction than the area of the weather strip device which interacts with the cover element. The longitudinal legs of the weather strip device also have profiled portions which differ in diameter in the roof transverse direction. In the vehicle roof known from the patent document DE 20 2017 105 940 U1, the wider profiled portion assigned to the fixed roof element extends to the rear transverse leg of the weather strip device. However, the width of the weather strip device is at the expense of the visual appearance of the finished vehicle roof. SUMMARY

[0003] It is an object of the invention to provide an openable vehicle roof of the type mentioned at the outset, in which the width of the weather strip device is ideally adapted to the technical requirements.

[0004] According to the invention, this object is achieved by an openable vehicle roof having the features of the application.

[0005] According to the application, an openable vehicle roof is proposed, which comprises a fixed roof element and a cover element, by means of which a roof opening, in particular arranged in front of the fixed roof element, can be closed. In order to seal the transition between the fixed roof element and the cover element on one side and the roof skin on the other side, a weatherstrip device is provided, which is formed in a frame-like manner and comprises longitudinal legs, which are divided into three profile sections on either side of a vertical longitudinal center roof plane. The first profile section arranged in front interacts with the cover element. The second profile section interacts with the fixed roof element and in particular seals an area through which a tilt lever of a displacement kinematics moves when the cover element is tilted. The third profile section arranged behind the second profile section also interacts with the fixed roof element, but is arranged outside the area through which the respective tilt lever of the displacement kinematics moves when the cover element is moved. The second, wider profile section can thus be kept short and corresponds to no more than the length required for the displacement kinematics when the cover element is moved. By virtue of the narrower design of the third profile section, it is also possible to continue the weatherstrip device in a uniform weatherstrip profile cross section in the rear transverse leg. The required curved shape of the weatherstrip profile cannot be easily achieved with a wide profile section.

[0006] The weatherstrip device of the openable vehicle roof according to the application is in particular attached to the roof frame or to the web or rib of a rail formed on the roof frame. The fixed roof element is preferably connected to the rail or the roof frame via a polyurethane edge foam. The weatherstrip device according to the application rests against the edge foam. The edge foam in the area of the third profile section of the weatherstrip device is preferably wider in the vehicle transverse direction than the foam in the area of the second profile section.

[0007] In a preferred embodiment of the openable vehicle roof according to the application, the weatherstrip device comprises four profile elements, wherein a first profile element forms the first profile section of the longitudinal leg and the front transverse leg, a second profile element forms the third profile section of the longitudinal leg and the rear transverse leg, and a third profile element and a fourth profile element form the two second profile sections of the longitudinal leg.

[0008] In a preferred embodiment of the openable vehicle roof according to the application, the third profile section of the longitudinal leg has a cross section corresponding to the cross section of the first profile section of the respective longitudinal leg in order to keep the tooling costs for manufacturing the profile sections low. In an embodiment comprising four profile elements, the first profile element and the second profile element can thus be manufactured using the same extrusion tool.

[0009] In order to achieve a harmonious transition between the profile sections of the longitudinal legs, the longitudinal legs of the weatherstrip arrangement comprise a front molded part arranged between the respective first profile section and the respective second profile section and a rear molded part arranged between the respective second profile section and the respective third profile section, the front and rear molded parts defining a continuous transition between the respective profile sections.

[0010] Preferably, the molded parts are each vulcanized or injection molded onto the profile sections. For example, they are made of EPDM material or TPV material. In order to also keep the tooling costs for manufacturing the molded parts low, it is advantageous if the front molded part of one longitudinal leg corresponds to the rear molded part of the other longitudinal leg. Thus, the two molded parts are identical components, the front molded parts being formed symmetrically to each other with respect to the vertical longitudinal center top plane.

[0011] Furthermore, in a particular embodiment of the vehicle roof according to the application, each profile section comprises a weatherstrip head forming the actual sealing area and which can be a cavity seal, and a weatherstrip base having a groove into which a holding rib of the roof frame engages. The weatherstrip base is made of EPDM material, for example in particular EPDM solid rubber, while the weatherstrip head can be made of porous rubber, for example EPDM porous rubber.

[0012] In order to form the first profile sections of the longitudinal legs interacting with the cover element as narrow as possible, they comprise an insert which, in a particular embodiment of the vehicle roof according to the application, is formed strip-like and extends in longitudinal and vertical direction with respect to the respective longitudinal leg, the insert preferably being made of metal. The insert provides the necessary stiffness and dimensional stability to the profile sections. The insert allows the first profile section to stand on the roof frame with the respective weatherstrip base which is ungrooved and unchanneled on the underside and is configured to be clamped between two holding ribs of the roof frame. The weatherstrip head is arranged on the weatherstrip base.

[0013] In order to also be able to guide the weatherstrip area of the weatherstrip arrangement in a dimensionally stable manner in the corner region of the cutout of the roof skin, the weatherstrip arrangement has a corner region between each longitudinal leg and transverse leg, each corner region being provided with a support element which is molded on the weatherstrip arrangement. The support element can be provided with a water outlet.

[0014] In particular, the support element can comprise a corner piece which is arc-shaped and follows the curvature of the weatherstrip head of the weatherstrip arrangement. Since the weatherstrip base cannot be formed cleanly and neatly in a bend due to its width, the support element can replace the weatherstrip base of the profile section in the curved region. However, it is the inserted corner piece which provides the curvature instead of the weatherstrip base.

[0015] The waterproofing strip base preferably forms an outlet channel which is delimited on one side by the waterproofing strip head and on the other side by a sealing lip which adjoins the top skin from below and / or the region of the vehicle body to which the top skin is fixed.

[0016] In order to prevent the longitudinal legs of the waterproofing strip arrangement from being displaced when the displacement movement mechanism of the top opening system is actuated, they preferably have a fixing device which fixes at least a portion of the respective longitudinal leg in the longitudinal direction to the top frame.

[0017] In one particular embodiment of the openable vehicle top according to the application, the fixing device comprises a protrusion which is formed on one of the moulded parts and engages in a recess in the top frame. The protrusion works in a stopper-like manner. In particular, the recess can be an interruption in the holding rib or holding web on which the waterproofing strip arrangement is mounted.

[0018] The application also relates to an openable vehicle top comprising a vehicle top skin which surrounds a top cutout, a fixed top element and a top opening are formed in the top cutout in a frame-like manner by means of an inner edge, the openable vehicle top comprises a top opening system with a cover element and a displacement movement mechanism, the cover element being movable by means of the displacement movement mechanism between a closed position in which the top opening is closed and an open position in which the top opening is at least partially open, a circumferential frame-like waterproofing strip arrangement is arranged on the inner edge of the top skin, the waterproofing strip arrangement interacts with the fixed top element and the cover element of the top opening system and comprises longitudinal legs on either side of a vertical longitudinal central top plane, and has front and rear transverse legs, the longitudinal legs of the waterproofing strip arrangement comprise a first profile portion which interacts with the edge of the cover element and a second profile portion which interacts with the edge of the fixed top element, the second profile portion being wider than the first profile portion in the top transverse direction, the first profile portion of the longitudinal legs comprises an insert which is formed as a strip and extends in the longitudinal and vertical direction relative to the respective longitudinal leg, and which is preferably made of metal.

[0019] It is clear that the vehicle top can also at least partially comprise any combination of the features described in connection with the vehicle top according to the application.

[0020] Further advantages and advantageous configurations of the subject matter of the application are clear from the description, the drawings and the claims. BRIEF DESCRIPTION OF DRAWINGS

[0033] Figures 1 to 10 The vehicle roof 10 is shown, which is formed as a panoramic roof and has a top cutout 12 in which a modular insert 14 is provided.

[0034] The top cutout 12 of the vehicle roof 10 is surrounded in a frame-like manner by a top skin 13, which is rigidly or immovably mounted relative to the vehicle body and fixed to the lower top structure 40. An insert 14 is connected to the lower top structure 40 from below.

[0035] The modular insert 14 comprises a fixed top element 16 which comprises a glass panel 18 provided with an edge foam 20 made of polyurethane material and rigidly or immovably connecting the glass panel 18 to a frame 22 of the insert 12.

[0036] A top opening 24 which can be closed by a movable cover element 26 is provided in the insert 14 and thus in the top cutout 12 and in front of the fixed top element 16. The cover element can be moved by a displacement kinematics 28 between a closed position (shown) in which the top opening 24 is closed and an open position (not shown) in which the top opening 24 is at least partially open. In the open position, the cover element 26 is arranged above the fixed top element 16. The cover element 26 further comprises a glass panel 30 provided with an edge foam 32 made of polyurethane material. Figure 1 and Figure 2 Figure 3

[0037] The frame 22 of the insert 14 comprises two longitudinal legs 34A and 34B which extend in the top longitudinal direction and are connected to each other by a front transverse frame portion 36 in the front and a rear transverse frame portion 38 in the rear.

[0038] For sealing the transition between the top skin 13 and the insert 14 or its fixed top element 16 and its cover element 26, a circumferential frame-like flashing device 42 is provided which is shown separately in Figure 4 The flashing device 42 is connected to the frame 22 of the insert 14. On either side of a vertical longitudinal center top plane, it comprises a longitudinal leg 44A or 44B and a front transverse leg 46 connecting the two longitudinal legs 44A and 44B to each other in the front and a rear transverse leg 48 connecting the two longitudinal legs 44A and 44B to each other in the rear.

[0039] From the front transverse leg 46 to the rear transverse leg 48, the longitudinal legs 44A and 44B comprise a first profile portion 50, a second profile portion 52 and a third profile portion 54.

[0040] ​​The first profiled portion 50 interacts on one side with a respective inner edge 56 of the top skin 13 defining the top cutout 12 and on the other side with a respective lateral edge 58 of the cover element 26. The second profiled portion 52 interacts on one side with a respective inner edge 56 of the top skin 13 and on the other side with a respective lateral edge 60 of the fixed top element 16 formed by the edge foam 60. The profiled portion 54 also interacts with a respective inner edge 56 of the top skin 13 and a respective lateral edge 60 of the fixed top element 16 formed by the edge foam 60. The rear transverse leg 48 of the waterproofing strip arrangement 42 interacts with the top skin 13 and the fixed top element 16, while the front transverse leg 46 interacts with the top skin 13 and the cover element 26.

[0041] From Figures 4 to 6 It can be seen that the second profiled portion 52 is formed wider in the top transverse direction than the first profiled portion 50. The third profiled portion 54 in turn has the width of the first profiled portion 50 and is thus narrower than the second profiled portion 52.

[0042] In order to achieve a continuous transition between the individual profiled portions, the longitudinal legs 44A and 44B have a front molded portion 62A or 62B and a rear molded portion 64A or 64B. The molded portions 62A and 62B are arranged between the first profiled portion 50 and the second profiled portion 52, and the molded portions 64A and 64B are arranged between the second profiled portion 52 and the third profiled portion 54 of the longitudinal legs 44A and 44B. The molded portions 62A, 62B, 64A and 64B are each injection-molded or vulcanized components and are made of a plastic material, in particular an EPDM material or a TPV material. They are connected to the respective molded portions 50, 52 and 54 by vulcanization. The molded portions 62A, 62B, 64A and 64B each widen against the edge foam 60 of the fixed top element 16, starting from the narrower profiled portion 50 or 54 to the wider profiled portion 52, the transition to the profiled portion occurring flush on both sides.

[0043] In the region of the slot 65, the holding ribs 82 of the frame 22 engage into the slot 65, each molded portion 62A, 62B, 64A and 64B having a protrusion 108 which forms a stop and engages into an interruption or recess 110 of the holding rib 82. The longitudinal legs 34A and 34B are thus relieved from displacement in the longitudinal direction.

[0044] In particular, Figure 4The waterproof liner assembly 42 is shown to include four profile elements interconnected via molding sections 62A, 62B, 64A, and 64B: a first profile element 66, which is U-shaped in top view and forms a front transverse leg 46 and two first profile portions 50; a second profile element 68, which is also U-shaped in top view and forms a rear transverse leg 48 and a third profile portion 54; a third profile element 70, which forms a second profile portion 52 of a longitudinal leg 44A; and a fourth profile element 72, which forms a second profile portion 52 of a longitudinal leg 44B. Profile elements 66 and 68 have the same cross-section.

[0045] Furthermore, the waterproof liner assembly 42 includes a support element 74, which is formed as a feature in each of its corner regions. The support element is formed as a foamed polyurethane molded part and is connected to the corresponding profile element 66 or 68 by vulcanization. Each support element 74 defines the arc of the corresponding profile element 66 or 68 in the corner region of the waterproof liner assembly 42 and is provided with a water outlet 75.

[0046] like Figure 5 As can be seen, the first profile portion 50 of the waterproof liner device 42 all includes a waterproof liner head 76, which is made of EPDM porous rubber and forms a tube seal and an actual waterproof liner element, interacting with the top skin 13 and the cover element 26. The waterproof liner head 76 is disposed on a profile-shaped waterproof liner base 78 made of solid EPDM rubber, and through the waterproof liner base 78, the profile portion 50 is attached to the corresponding longitudinal support leg 34 of the top frame 22, and also forms a guide rail 100 for the displacement movement structure 28 of the top opening system. The waterproof liner base includes a vertical longitudinal groove 80 into which the retaining rib 82 of the frame 22 engages. In addition, the waterproof liner base 78 includes a transverse support leg 84 that transitions to an outer sealing lip 86, which abuts against the top skin 13 and / or the lower top structure 40 from below, thereby forming a water channel 88.

[0047] The profile portion 52 also has a tubular waterproof liner head 90 made of foam rubber, which interacts with the top skin 13 and the fixed top element 16, and is located on a waterproof liner base 92 made of EPDM, which has a vertical groove 94 into which the retaining rib 82 of the frame 22 engages. The waterproof liner base 82 also has a lateral support leg 96, which is limited by an outer sealing lip 98, such that the profile portion 52 also forms a water channel 88. The water channel 88 allows any infiltrated water to be directed to the support element 74 in the corner area of ​​the waterproof liner assembly 42, from where the water can be discharged in a suitable manner through an outlet 75, for example via a pipe leading to the wheel arch of the corresponding vehicle.

[0048] The second profiled portions of the weatherstrip arrangement 42 are each arranged above a guide rail 100 in which the inclined bar 102 of the displacement kinematics 28 is guided in the vehicle longitudinal direction when the cover element 26 is moved. In this case, the inclined bar 102 runs through a slot which is formed between the inner edge 56 of the top skin 13 and the respective lateral edge 60 of the fixed top element 16 and is filled by the respective second profiled portion 52. When the cover element 26 is moved by the respective inclined bar 102, the weatherstrip head 90 of the second profiled portion 52 is deformed or moved to the side.

[0049] The profiled portion 52 extends in the rearward direction to a rear stop position of the inclined bar 102. There, the second profiled portion 52 transitions via molding portions 64A and 64B to the third profiled portion 54. The front molding portions 62A and 62B are arranged in the parting line region between the fixed top element 16 and the cover element 26 in its closed position. In the basic position, the molding portions 62A, 62B, 64A and 64B each abut the edge foam 20 of the glass panel 18 of the fixed top element 16 in a form-fitting manner, which means that the edge foam 20 follows the shape of the molding portions 62A, 62B, 64A and 64B.

[0050] Figure 11 A weatherstrip arrangement 42' is shown which shows an alternative embodiment and differs from the above-described weatherstrip arrangement in that it comprises a first profiled portion 50' which is a component part of a continuous front profile element 66' which interacts with the cover element 26. The profiled portion 50' comprises a weatherstrip head 76' which is formed in a tubular seal and which is located on a weatherstrip base 78' by which the respective profile portion 50' is fixed to the top frame 22. The weatherstrip base 78' is clamped between two longitudinal ribs 103 which are hook-shaped in cross section. The weatherstrip base 78' is trough- and groove-free on its underside and has a strip-shaped metal insert 106 in a support portion 104 which is a reinforcing element to which the weatherstrip head 76' is connected so that the respective profiled portion 50 cannot be moved or deformed in an unintended manner as a result of mechanical impacts when the cover element 26 is moved. As a result of the metal insert 106, the retaining webs which engage in the respective slot of the weatherstrip base 78' can be omitted. As a result, the weatherstrip head 50' can be formed more narrowly compared to the embodiment with retaining slots, which in turn has a positive effect on the appearance of the vehicle roof.

[0051] In addition thereto, the weatherstrip arrangement 42' corresponds to the embodiment according to Figures 1 to 10 which is why reference is made to the above description.
