Description

The present invention relates to a vehicle with a seal according to the preamble of claim 1.

In a generic vehicle with a sealing arrangement, the sealing arrangement has a seal with a sealing base, by means of which the seal is attached to a vehicle body or a vehicle component that is fixedly connected to the vehicle body or that is movable relative to it. The sealing foot is at least partially (or completely) removed from the seal with a cut or punched section.

A seal for a generic vehicle is from the WO 2015/185122 A1 known. In the case of the seal disclosed in this publication, a sealing foot is cut in sections in order to allow easy access to adjusting screws which are arranged in the area of the sealing foot.

Known seals for vehicles are glued to the vehicle by means of such a sealing base or fastened to the vehicle by inserting the sealing base into a fastening groove.

By trimming or punching a section of the sealing base, that is to say at least partially removing the sealing base, the seal can be optimized for positions that are critical in terms of installation space. The disadvantage here, however, is that the original fastening concept, which is intended to secure the exact position of the seal in the installation position, does not apply locally to this section of the seal. Such undefined sections have a negative impact on the appearance and functionality of the seal. The seal can be displaced locally here and also develop a different deformation behavior compared to areas that have not been trimmed, which can negatively affect the appearance and also the function of the seal.

It is the object of the present invention to provide a vehicle with a sealing arrangement which overcomes these disadvantages.

This object is achieved by a vehicle according to the characterizing part of claim 1.

In the vehicle according to the invention, the seal is fixed and / or attached to the vehicle body or to the vehicle component in the region of the trimmed or punched section by means of a separate fastening element.

Such a separate fastening element advantageously ensures the correct positioning of the seal in the punched or trimmed seal section and results in a uniform sealing and deformation behavior of the seal. A continuously constant position over the entire length of the seal is therefore achieved in that the seal is locked in the trimmed or punched section area by means of the separate fastening element.

Preferred configurations of the present invention emerge from the subclaims.

In a first preferred embodiment of a vehicle according to the invention, the fastening element has a clip or is designed as a clip, the clip partially encompassing the seal and preventing the seal from slipping or shifting in the cut or punched section. Such a clamp offers the advantage of a simple and secure fixation of the trimmed sealing section, which it can partially encompass.

The fastening element preferably has a section with a U-shaped cross section, which partially receives the seal, two legs of the U-shaped cross section preferably being oriented horizontally. The bracket explained above can be defined by this U-shaped cross section.

Particularly preferred is an embodiment in which the section with the U-shaped cross-section with the two legs of the U-shaped cross-section grips and fixes a trimmed or punched residual cross-section of the seal foot remaining on the seal in a force-fitting and / or form-fitting manner.

The seal can thus simply be inserted or plugged into the area between the two legs of the U-shaped cross section and clamped by means of the legs.

As an alternative or in addition, a section connecting the two legs of the U-shaped cross-section can, together with one leg, support and fix a trimmed or punched residual cross-section of the sealing foot remaining on the seal on two mutually perpendicular sides. The seal can thus be supported and fixed from three sides by the two legs and by the connecting section. The fixing of the seal in this area via a groove for inserting a sealing base or via an adhesive connection of the sealing base can therefore be dispensed with without significant disadvantages.

In a particularly preferred embodiment, at least one leg of the U-shaped cross section is directed inward and / or curved. This is to be understood as meaning that the two legs of the U-shaped cross section are no longer aligned in parallel, but rather at least one leg extends in a direction towards the adjacent leg. This offers the advantage that the clamping effect and thus the fixing of the fastening element around the remaining cross-section of the sealing base is improved.

In order to improve the frictional connection even further, the fastening element can have a protruding rib by means of which the seal is prevented from slipping or shifting in the cut or punched section.

Such a protruding rib can in particular be arranged within the U-shaped cross section explained above and is then preferably oriented essentially in the direction of the center of the U-shaped cross section. This offers the advantage that the clamping effect of the separate fastening element is further improved.

In a particularly preferred embodiment of this variant, the fastening element is designed as an extruded metal profile which forms the clamp with the U-shaped cross section, and the protruding rib is extruded onto the U-shaped cross section. A corresponding protruding rib is thus formed on during the production of the fastening element.

Conversely or in addition, a thickening or additional material can also be provided on the seal itself in the cut or punched section of the seal in order to increase the frictional connection. Such an additional material or a thickening can be extruded, injected or glued onto a remaining cross section of the trimmed or punched sealing foot, whereby the frictional connection of the U-shaped cross section with the remaining cross section of the sealing foot is also increased.

The additional material or this material thickening can be attached to a basic shape of the seal subsequently. This offers the advantage that the additional material can consist of a different base material than the seal itself, so that, for example, a material can be used which is optimized with regard to the fixing of the seal in the cut or punched section.

The sealing arrangement is preferably arranged on a vehicle roof or a vehicle roof module.

In a particularly preferred embodiment of the present invention, the vehicle has a cover flap for optionally covering an opening in a vehicle body in a closed position and at least partially exposing the opening in a release position, and the trimmed or punched section is arranged in the area of the cover flap. This offers the advantage that the seal takes up less space in the area of the openings. In particular, it can be avoided that the sealing foot protrudes into the opening and restricts access to the fastening point in the release position.

It can be provided here that the fastening element, for example the U-shaped cross section of the clip, which the fastening element can have, simultaneously forms an edge of the opening. At this edge, in a closed position of the cover flap, an underhand grip or a locking lug can enter into a force-fit connection with the U-shaped cross section and thus fix or lock the cover flap in the closed position. To release the cover flap, the locking connection of the locking lug can then be released manually.

In all of the illustrated embodiments of the present invention, the sealing foot of the seal can be both glued and inserted into a fastening groove outside the trimmed or punched section on the vehicle body or on the vehicle component. This offers a reliable fixation of the seal in areas outside the punched or trimmed sections.

Therefore, the seal need not be fixed and / or fastened to the vehicle body or to the vehicle component by means of a separate fastening element outside the region of the trimmed or punched section, and separate fastening elements can be dispensed with here.

In the following, the invention is explained in greater detail using the figures. It shows:

• 1 : a plan view of a corner area of a vehicle roof;
• 2 : a cross section along the line AA of the 1 ;
• 3 : a cross section along the line BB of 1 ;
• 4th : a further development of the embodiment according to 3 ; and the
• 5 and 6 : further embodiments of the invention.

1 shows a plan view of a vehicle body of a vehicle according to the invention. The longitudinal direction of the vehicle runs in the 1 left to right. Side windows and vehicle doors as well as the windshield and other vehicle parts are not shown or not yet mounted.

Along a longitudinal spar 24 of the vehicle is a fixed panel 36 arranged, which is also aligned in the vehicle longitudinal direction and on the longitudinal spar 24 connects. Inside the fixed screen 36 is a cover flap 12 provided in the 1 as is shown in the following figures in a closed position in which they have an opening below 14th (please refer 3 ) covers and thus closes. In the opening 14th under the cover flap 12 a fastening point is provided for a removable roof rail, which can be secured by removing or opening the cover flap 12 can be released for mounting the roof rails.

Along the fixed screen 36 is a seal 16 also arranged in the longitudinal direction of the vehicle and serves to create a gap between the fixed panel 36 and the longitudinal spar 24 to seal.

2 FIG. 11 shows a cross section through the vehicle of FIG 1 along the line AA. The one in the representation of the 2 cut longitudinal strut 24 of the 1 forms part of the vehicle outer skin here 38 out. Adjacent to the vehicle outer skin 38 and further inside in the vehicle roof in the horizontal direction is the fixed panel 36 arranged. On the underside of the fixed panel 36 this forms a rib 44 facing down. By means of a bond 42 is the seal in this area 16 from below to the fixed panel 36 glued, with the rib 44 the fixed aperture 36 as a stop and guide for positioning the seal 16 serves. In the assembled state of the seal 16 to the underside of the fixed bezel 36 supports the rib 44 the seal 16 thus preventing the seal from shifting 16 if this is with the longitudinal spar 24 the vehicle comes into sealing effect. The seal 16 points to improve the sealing effect with the longitudinal spar 24 a sealing lip 17th which do not interact with the longitudinal spar 24 would be aligned horizontally as shown, but is actually pivoted elastically and on the longitudinal spar 24 fits tightly. The seal 16 furthermore has a sealing base 20th at the point of the cross section AA (i.e. outside the area of the cover flap 12 ) about the bond 42 with the underside of the fixed bezel 36 connected to the seal 16 on the fixed panel 36 to fix.

3 shows a cross section along the line BB of FIG 1 through an area of the vehicle body in which the cover flap 12 is arranged. Below the cover flap 12 is the opening 14th in the closed position of the cover flap 12 covered and in a release position of the cover flap 12 is accessible from above. By releasing the opening 14th an area below becomes accessible, which can be used to mount a removable roof rail or, alternatively, a roof rack. To set the cover flap 12 in the closed position, this has a locking lug 26th and an underhand grip 22nd by means of which the cover flap 12 can be locked in the vehicle roof. To release the opening 14th can the cover flap 12 by releasing the locking lug 26th pivoted or completely removed from the vehicle roof.

In the area of the cover flap 12 and the opening 14th is the fixed aperture 36 designed accordingly narrower. The cut of the 3 runs just like that of the 2 also through poetry 16 of the 1 and 2 . However, the seal is 16 in the area of the opening 14th trimmed or punched so that opposite the uncut sealing base 20th of the 2 here only a remaining cross-section 18th on the seal 16 remains. This has the advantage that the clear horizontal width of the opening 14th not because of the comparatively long uncut sealing base 20th of the 2 is restricted. This has the advantage that the seal 16 not in the opening 14th protrudes and obstructs access to the attachment point of the removable roof rail.

Because the large-area bonding 42 of the uncircumcised sealing foot 20th of the 2 in the area of the cross section of the 3 is omitted or at least has to be smaller, is an additional fastening element 10 provided, by means of which the seal 16 is fixed and fastened directly or indirectly in the area of the trimmed or punched section on the vehicle body. The fastener 10 has a U-shaped bracket or is designed as such a bracket and surrounds a remaining cross-section 18th of the trimmed sealing foot on three sides. Only the third side of the remaining cross-section 18th the trimmed sealing foot is not from the fastener 10 surrounded so when assembling the seal 16 these are simply inserted, and also the sealing lip 17th the assembled seal 16 from the U-shaped bracket of the fastener 10 exit and with the longitudinal spar 28 can come into sealing effect.

In the embodiments of 3 can depending on the thickness of the remaining cross-section 18th of the trimmed sealing foot at least one leg 31 the U-shaped bracket and a "bottom" of the U-shaped bracket that acts as a connecting section 33 who have favourited legs thigh 31 connects, the seal 16 so support that they can even without the large-area gluing 42 of the uncircumcised sealing foot 20th of the 2 is reliably held in the desired position. In particular, the separate fastening element supports 10 the seal 16 against the force exerted by the seal 16 due to the elastic deformation of its sealing lip 17th learns when it is deformed to develop the sealing effect. In the embodiment of 3 the sealing lip is used in the formation of the sealing effect 17th bent upwards, causing on the seal 16 a horizontal force component towards the center of the vehicle roof and a vertical force component act. The U-shaped bracket of the fastener 10 supports the remaining cross-section 18th of the trimmed sealing foot against these two force components.

The two legs 31 and the connecting section 33 thus form a form fit or material fit with the remaining cross section 18th of the trimmed sealing base to secure the seal in place 16 on the vehicle roof, so that the large-scale bonding 42 in the uncut section of the seal 16 can be omitted here.

In the 3 is another seal 40 shown showing the fixed bezel 36 seals against a fixed glazed panoramic roof or a sliding roof, not shown.

By means of the embodiments of 4th , 5 and 6 additional measures and alternatives are proposed which offer the advantage that the seal 16 are fastened in the trimmed or punched sections even more stable against displacement.

In the 4th is a thigh 32 the U-shaped bracket of the fastening element 10 inwards to the remaining cross-section 18th of the trimmed sealing foot 18th bent towards The fastener 10 is preferably designed as an extruded metal rail, so that the leg 32 relatively slightly upwards to fix the seal 16 can be bent. This creates a better clamping effect between the remaining cross-section 18th the trimmed sealing foot and the fastening element 10 reached.

In the embodiment according to 5 has the fastener 10 two ribs 28 on, which is arranged on the two inner sides of the legs of the U-shaped bracket and inward to the remaining cross-section 18th of the trimmed sealing foot are aligned. These ribs 28 can be used simultaneously with the fastener 10 can be formed easily and inexpensively in a single extrusion process. Alternatively, appropriate ribs can be used 28 can also be retrofitted to the fastening element, for example glued or molded on. This has the advantage that the ribs 28 only locally in the area of the cut or punched section of the seal 16 can be arranged.

In the embodiment of 6 is additional material in the form of a thickening 34 at the remaining cross-section 18th of the trimmed sealing foot 8th arranged. This also offers the advantage of a better clamping effect between the fastening element 10 and the seal 16 .

The additional material of the thickening 34 (or several thickenings) can, for example, in a (second) extrusion process locally in the region of the cut or punched section of the seal 16 arranged or on the seal 16 be glued or injected. Alternatively, the thickening 34 also to the seal 16 be glued on. In both variants, the same material can be used from which the seal is made 16 itself exists, or an alternative material, which in terms of the clamping effect with the fastening element 10 is optimized. Another alternative can also be during the production of the seal 16 a variable cross-section of the seal 16 be formed, with a thick cross-section in the area of the separate fastening element 10 the clamping effect increases here.
