Description

[0001] The invention relates to a sealing arrangement for a mirror triangle of a motor vehicle side door.

[0002] On the front side doors of motor vehicles, especially passenger cars, the triangular area in front of a corresponding side window or above a corresponding sill edge is usually referred to as the mirror triangle, in which the respective exterior mirror for each side of the vehicle is usually mounted. Such a side door is already known, for example, from DE 20 2009 003 452 U1 and from DE 10 2008 038 845 A1.

[0003] A sealing arrangement is already known from the BMW X1 (E84 series) which includes a component of the mirror triangle that, via a support element, abuts a sealing edge of a window guide. This sealing edge is supported by the support element against a sealing edge of a cover of the mirror triangle. The support element is currently adhered along its entire length to the inside of the sealing edge of the window guide using adhesive tape. This ensures that the sealing edge of the window guide, which forms the transition between the mirror triangle and the door pillar, is sufficiently supported by the support element, preventing, for example, a gap from forming between the window guide and the outer cover of the mirror triangle.

[0004] The support element, which is currently made of rubber extrudate, not only requires a complex and expensive manual gluing process, but can also come loose during transport of the window guides.

[0005] Furthermore, from DE 199 37 000 A1 and DE 10 2013 215 933 A1, various components such as side doors or the like are known for use in motor vehicle construction, in which respective components such as window guide rails or the like are foamed into plastic foam parts.

[0006] The object of the present invention is therefore to provide a sealing arrangement and a method for manufacturing such a sealing arrangement which enable a simpler manufacturing and assembly process.

[0007] This problem is solved according to the invention by a sealing arrangement with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0008] In order to create a sealing arrangement that enables a simpler manufacturing and assembly process, it is provided according to the invention that the component of the mirror triangle is formed from a plastic foam component and serves as an outer seal of the mirror triangle, wherein the support element and the plastic component of the mirror triangle are materially bonded to form a single unit by encasing the support element with the plastic of the component.

[0009] According to the invention, it is provided that the component of the mirror triangle, which adjoins the sealing edge of the window guide by means of the respective support element, is combined into a component unit with the corresponding support element.

[0010] The advantage of a material-bonded connection between the mirror triangle component made of a first plastic and the support element made of a second plastic is particularly that a plastic composite can be created in a simple way, which is especially easy and cost-effective to manufacture.

[0011] The mirror triangle component is formed from a foam component, which surrounds the support element and thus connects them at least materially, but also form-fittingly. Such a component enables a particularly cost-effective and easy-to-manufacture assembly consisting of the support element and the mirror triangle component.

[0012] The mirror triangle component is designed as an external seal, which is positioned on the outside of a door strike plate or similar component already present in the door frame. Thus, the mirror triangle component has a dual function: on the one hand, it provides a seal, and on the other hand, it holds, for example, the corresponding exterior mirror in place.

[0013] In a further embodiment of the invention, it has proven advantageous if the support element is made of a harder plastic, like the component of the mirror triangle. Thus, due to the harder plastic, the support element can perform the supporting function of the corresponding sealing strip of the window guide in a particularly favorable manner.

[0014] Further details of the invention will become apparent from the description of a preferred embodiment.

[0015] This shows: Fig. 1a, Fig. 1b a partial side view of a mirror triangle of a motor vehicle side door with the cover of the mirror triangle omitted, whereby a component is visible which adjoins a sealing edge of a window guide by means of a strip-like support element, as well as a partial and opposite Fig. 1a Enlarged sectional view of the sealing arrangement in the area of ​​the mirror triangle along a line Ib - Ib in Fig. 1a indicated cutting plane; Fig. 2a, Fig. 2b, Fig. 2c respective perspective views of the support element and the building element of the mirror triangle in separate representations as well as in a holistic representation combined to form a building unit.

[0016] Fig. Figure 1a shows a partial side view of a passenger car side door 10, revealing the area of ​​a mirror triangle 12, which extends forward essentially along the front of a side window 14 of the car door 10. The mirror triangle 12 extends downwards at least essentially to the level of a shaft cover 16, below which a door skin 18 is visible. The mirror triangle 12 is essentially bounded upwards by a window guide 22 made of plastic, which is designed, for example, as a rubber seal. This guide 22 receives the upper edge 20 of the side window 14 when closed and also seals the car door 10 against corresponding pillar and roof frame elements of the body shell, such as the A-pillar and the roof frame.

[0017] Fig. 1b shows a sectional view through the motor vehicle side door 10 in the area of ​​a line Ib-Ib in Fig. 1a indicated section plane running in the transverse direction of the vehicle.

[0018] Together with Fig. 1a is made from Fig. 1b It can be seen that the window guide 22 is attached to a flange 24 of a door frame 26 and, in addition to an upper edge 28, includes a sealing lip 30 extending behind it in the transverse direction of the vehicle, with which the window guide 22 abuts the A-pillar or the roof frame in the aforementioned manner. On the side facing away from the edge 28, the window guide 22 includes a lower sealing edge 32, which, together with another sealing edge 34 of a cover 36 of the mirror triangle 12, forms a joint 38. It can be seen that the sealing edge 34 of the cover 36 overlaps the sealing edge 32 of the window guide 22 from the outside. The cover 36 is in Fig. 1a is not shown for the sake of clarity, but essentially serves to frame and cover a corresponding exterior mirror of the vehicle. It should be mentioned, however, that the present arrangement is also suitable for vehicle doors 10 that do not have an exterior mirror or where the exterior mirror is attached elsewhere, for example to the outer door panel 18.

[0019] Furthermore, it is from Fig. 1b It is evident that on the outside of a door strike plate 42 of the door frame 26, which extends in the area of ​​the mirror triangle 12, a component 44 of the mirror triangle 12 is provided, which serves as an outer seal of the mirror triangle 12. This component 44 is formed by the omission of the cover 36 in Fig. 1a visible on the underside of the window guide 22 or on the upper side of the sill edge 16 and subsequently in connection with the Fig. 2b and Fig. 2c is described in more detail.

[0020] As also in combination the Fig. 1a and Fig. As can be seen in Figure 1b, the component 44 is arranged adjacent to the sealing edge 32 of the window guide 22 by means of a support element 46. This support element 46 is in Fig. 2a shown separately. It serves in particular to support the sealing edge 32 of the window guide 22 in the transverse direction of the vehicle, so that the joint 38 between the sealing edge 32 of the window guide 22 and the sealing edge 34 of the cover 36 remains closed. A sealing lip 48 of the window guide 22 is thereby in Fig. 1b is shown deformed in the assembled state, in that it is supported accordingly on the outside of the support element 46.

[0021] In Fig. Finally, 1b also shows a window guide rail 50 for the side window 14, so that it is guided tightly at the front edge 21.

[0022] In order to achieve a particularly favorable sealing arrangement, it is planned that the in Fig. 2a shown support element 46 and the one in Fig. 2b separately shown component 44 of the mirror triangle 12 in the form of the seal, which is applied to the outside of the door strike plate 42, to form a component unit according to Fig. 2c are connected. It is therefore intended to combine the support element 46, which is essentially designed as a plastic strip, and the component 44 in the form of a single plastic part, in order to simplify the manufacturing process and assembly.

[0023] In the present case, the component 44 is formed from a foam component produced in a mold. The support element 46 is first inserted into the mold and bonded to the plastic of the component 44, at least materially, but in this case also form-fittingly, or rather, encased in foam. The particular advantage in this case is that the support element 46 is attached directly to the component 44, thus forming a single assembly 40 ( Fig. 2c) is formed, as this results in simple assembly and support of the corresponding sealing edge 32 of the window guide 22.

[0024] In the present case, the support element 46, in the form of a strip, is made of a second, harder plastic than the component 44, which consists of the foam component. This is intended to particularly take into account the support function of the support element 46 and the sealing function of the component 44. Reference symbol list 10.
