[0004] Seal with shielding element

[0005] The invention relates to a seal, in particular a door seal, with a mounting area having a mounting carrier for mounting the seal on a closing element, in particular a door, or a frame, in particular a door frame, and an elastically deformable sealing lip.

[0006] These types of seals are used in a wide variety of applications, for example, to seal one room against another. The two rooms are typically connected by an opening, which can be closed using a locking element such as a door. This locking element is usually movable relative to a fixed frame, so that the two rooms are connected when the locking element is open and separated when it is closed. Besides doors, the term "closing device" can also refer to windows, hatches, flaps, covers, or similar elements. September 19, 2025 Our reference: 25-13-103

[0008] The seals now feature a mounting area that allows them to be installed either on the locking element side or on the frame side. This mounting area is often equipped with a mounting bracket that ensures the seal is securely attached to the locking element or frame.

[0009] The actual sealing effect is created by a sealing lip, which is usually positioned so that, in the closed position, it lies between the locking element and the frame and is elastically deformed in the closed position. This elastic deformation allows the sealing lip to press against the locking element or the frame, thus creating a sufficient surface contact and achieving a seal. Depending on the design of the sealing lip and also on the contact pressure exerted by the locking element on the frame or the seal in the closed position, the seal can not only prevent dust or small particles from passing from one room to another, but can also, in some cases, create a watertight or even airtight seal between the rooms.

[0010] While such seals have proven their worth and are used in very large quantities in a wide variety of applications, in practice, in addition to sealing against water or air, for example, there is often a need to ensure electromagnetic shielding. Such electromagnetic shielding may be particularly necessary if sensitive electronic components are located in one of the two compartments, as can be the case, for example, with server racks.

[0012] The invention thus sets itself the task of providing a seal with which electromagnetic radiation can also be shielded.

[0013] This problem is solved in a seal of the type mentioned above by the fact that the seal has a shielding carrier carrying an electrically conductive shielding element, which is designed as a solid material shielding carrier.

[0014] The shielding element ensures that the seal not only protects against environmental influences and the ingress of dust, dirt, water, or even air, but also provides shielding against electromagnetic radiation. This allows, for example, electronic components located in one of the rooms to be reliably protected from electromagnetic radiation.

[0015] For radiation protection, both the locking element and the frame can be designed to contact the shielding element, so that these two elements are electrically connected via the shielding element. In this way, the shielding element can provide potential equalization between the locking element and the frame.

[0016] The solid material construction of the shielding carrier allows it to exhibit good stability, which is particularly advantageous for large or heavy locking elements to ensure sufficient durability. "Solid material" in this context means that the shielding carrier as a whole has no internal cavities or inclusions. However, this does not preclude the shielding carrier from consisting of an open-pore material at a microscopic level. Furthermore, the use of a solid material shielding carrier reduces stress on the sealing lip, as it does not have to absorb the entire force when the locking element is closed, but rather the majority of the force is distributed. 19.09.2025 Our reference: 25-13-103

[0017] 4

[0018] Forces can be absorbed by the shielding support. The service life of the sealing lip can also be improved by using a solid shielding support.

[0019] With regard to the shielding support, it has proven advantageous for it to be designed as a stopper. This design allows the locking element to move against the shielding support during a closing movement, enabling the shielding support to absorb a portion of the locking element's kinetic energy. This reduces the mechanical stresses acting on the elastically deformable sealing lip, which is less stable than the shielding support.

[0020] In this context, it has proven advantageous for the sealing lip to be designed as a hollow chamber sealing lip. This design allows the sealing lip to deform reliably and elastically, thus providing sufficient sealing effect. In contrast to the shielding support, which is made of solid material, the sealing lip can therefore have a hollow profile in cross-section and can contain an internal cavity that gives the sealing lip high elasticity.

[0021] Regarding the materials, it has proven advantageous for the sealing lip to be made of rubber, particularly foam rubber. Ideally, the rubber should have an open-pore structure or be foamed, which is why the use of foam rubber is particularly beneficial. Foam rubber is characterized by its very low weight and high flexibility. Furthermore, foam rubber is water-repellent, which is also an advantageous property for a seal, as the sealing lip cannot become saturated with water. The sealing lip material should ideally have a density of approximately [missing information]. [Missing information] 19.09.2025 Our reference: 25-13-103

[0022] 5

[0023] 0.65 g / cm² 3 on, with deviations in the range of 0.05 g / cm² 3 are possible.

[0024] Regarding the shielding carrier, it has proven advantageous for it to be made of rubber, particularly soft rubber. Soft rubber is also characterized by good flexibility but is more stable than foam rubber. Furthermore, unlike foam rubber, soft rubber has a closed structure and therefore no open pores. The different materials also result in a shielding carrier made of solid material offering better stability than the softer and more flexible sealing lip. This means that, in addition to supporting the shielding element, it also acts as a stop for the closing element, thus relieving stress on the sealing lip. Moreover, the closed structure ensures that the shielding element adheres reliably to the shielding carrier. An open-pored structure could lead to the shielding element unintentionally detaching from the shielding carrier during operation and, for example, after prolonged use.

[0025] According to a further advantageous embodiment of the invention, it is proposed that the sealing lip be arranged on the outside of the seal and the shielding carrier on the inside of the seal. The sealing lip can thus face one compartment during operation, and the shielding carrier can face the other. The seal is advantageously arranged such that environmental influences such as dust, dirt, or moisture are kept away from the sealing lip, so that ideally they do not come into contact with the shielding carrier in the first place. The sealing lip can therefore act as protection for the shielding carrier against environmental influences. This protective function also ensures a reliable hold of the shielding element on the shielding carrier, which will be described in more detail below with regard to the design and the connection between the shielding element and the shielding carrier. 19.09.2025 Our reference: 25-13-103

[0026] This is explained in section 6. The outer surface of the seal thus corresponds to the area facing the space against which the other space is to be sealed. In this respect, this space can also be referred to as the exterior space and the other space as the interior space. The inner surface therefore corresponds to the side facing the interior space that is to be sealed against the exterior space. For example, the interior space could be the inside of a cabinet, especially a server cabinet, the interior of a vehicle, or even a living space.

[0027] From a geometric perspective, it has proven advantageous for the shielding support to have a conical geometry. The shielding support can thus have an overall elongated shape and a rod-like cross-section. The space required for the shielding support is therefore comparatively small, and it can be significantly narrower than the sealing lip. This is also related to the fact that the shielding support is relatively stable due to its solid material construction. Furthermore, the shielding support can extend essentially parallel to the sealing lip. Advantageously, the shielding support maintains a certain distance from the sealing lip so that it does not impede its elastic deformation. The shielding support can thus be decoupled from and spaced apart from the sealing lip; however, it can, of course, be indirectly connected to the sealing lip via the mounting area.

[0028] The shielding carrier can be rounded in the area that comes into contact with the locking element, so that when the locking element is closed, there is essentially a linear contact area between the locking element and the shielding carrier. A linear contact is sufficient for the electrical connection of the locking element, especially since the shielding carrier itself does not need to provide a seal. 19.09.2025 Our reference: 25-13-103

[0029] 7 because the sealing effect is taken over by the sealing lip and the rather flat contact of the closing element.

[0030] Furthermore, it has proven advantageous to connect the shielding support to the mounting area via a bending section. This bending section can be located at the base of the shielding support, thus opposite the end that comes into contact with the locking element. The bending section allows for elastic movement of the shielding support relative to the mounting area upon contact with the locking element or the frame. This enables the shielding support to yield or deflect upon contact with the locking element or frame, not only due to its inherent elastic deformation but also because of the bending section. This is particularly important for the stop function of the shielding support and reduces material stress as well as the forces acting on the locking element or the frame, for example, when the locking element is slammed shut at high speed.Furthermore, it can be ensured that, when the locking element is closed, the shielding support is pressed against the locking element or the frame from the inside with a certain force or preload to guarantee reliable electrical contact. If the mounting area is located on the locking element side, the shielding support can come into contact with the frame, and if the mounting area is located on the frame side, the shielding support can come into contact with the locking element. From a design perspective, the bending section can have a smaller cross-section than the shielding support, thus promoting elastic deformation in this area.

[0031] With regard to the shielding element, it has proven advantageous for it to extend from the shielding support to the mounting area. This design ensures that the shielding- 19.09.2025 Our reference: 25-13-103

[0032] The 8 element is in contact with both the locking element and the frame, and can therefore provide an electrical connection between the two elements.

[0033] According to a particularly advantageous embodiment, the shielding element is designed as a shielding foil. This allows the shielding element to be very thin and require only a very limited installation space. To ensure an electrical connection, the shielding element or foil can be made of metal or at least contain electrically conductive components. Therefore, the shielding element or foil can also consist of a plastic filled with conductive materials. With regard to the material, it has proven advantageous if the shielding element can achieve an attenuation of electromagnetic radiation between 80 and 90 dB, particularly in a frequency range between 100 MHz and 18 GHz.

[0034] Regarding the shielding foil, it has proven advantageous to adhere it to the shielding carrier, particularly to the shielding carrier and the mounting area. Thanks to the adhesive bond, the shielding foil can be easily applied even after initial installation. Furthermore, the shielding foil can also be easily removed later, for example, to replace it with a different shielding foil. This allows the appropriate shielding foil to be selected for a specific application. Repairing the seal, for example, if the shielding foil has worn out, can also be easily achieved by applying a new shielding foil.

[0035] Furthermore, it has proven advantageous to adhere the shielding foil to the inside of the shielding carrier, particularly to the inside of the shielding carrier and the mounting area. (Date: 19.09.2025 Our reference: 25-13-103)

[0036] 9

[0037] The design protects the shielding film and especially the adhesive layer from environmental influences and particularly from moisture, so that the adhesive film cannot detach even over a longer period of use.

[0038] To further improve adhesion, it has proven advantageous for the shielding element, particularly the shielding foil, to partially surround the shielding carrier and / or the mounting area. This surround creates a comparatively large contact area, ensuring good adhesion of the shielding foil. It is also advantageous for the end of the shielding foil to be positioned in a less exposed area, ideally one that is not accidentally touched. This prevents the ends of the shielding foil from detaching over time. Once the ends are no longer firmly bonded to the substrate, larger sections of the shielding foil can easily detach. Therefore, it has proven advantageous to position one end of the shielding foil on the side of the shielding carrier facing the sealing lip.The other end can be positioned between two retaining projections. The function and position of these projections will be explained in more detail below.

[0039] Regarding the connection of the seal to the locking element or the frame, it has proven advantageous if the mounting area can be clipped onto the locking element frame or the locking element itself. This clipping mechanism ensures very simple installation. The seal can be designed to be detachably connected to the locking element or the frame; however, permanent connections are also possible, for example, through the additional use of an adhesive. September 19, 2025 Our reference: 25-13-103

[0040] 10

[0041] Regarding the mounting bracket, it has proven advantageous for it to be made of steel, particularly spring steel. The mounting bracket can provide sufficient strength to the mounting area, ensuring that the seal can be reliably connected to the locking element or frame. A spring-like design of the mounting bracket is advantageous, allowing the mounting area to be clamped onto the locking element or frame. The mounting bracket then deforms elastically, generating a certain holding force due to its inherent tension. To meet these requirements, the use of steel, especially spring steel, has proven particularly effective. Spring steel exhibits excellent elasticity, which allows for a suitable clamping connection.

[0042] Regarding the mounting area, it has proven advantageous for the mounting bracket to be encased in rubber, particularly soft rubber. This encasement prevents the mounting bracket from coming into direct contact with the locking element or the frame, thus protecting these surfaces. The rubber encasement also improves the feel of the mounting bracket, leading to easier installation. The encasement and the shielding bracket can be made of the same material, allowing them to be monolithically bonded together. The use of soft rubber has proven particularly effective. The shielding bracket can be injection-molded onto the encasement. Ideally, the encasement or the soft rubber should have a Shore A hardness of 60. Deviations of 5 are acceptable.

[0043] Regarding the design of the assembly area, it has also proven advantageous if it has two legs, in particular an inner and an outer leg, and a receiving space arranged between the legs for receiving the 19.09.2025 Our reference: 25-13-103

[0044] 11

[0045] The seal has a U-shaped cross-section with two legs. The two legs can extend parallel to each other and be spaced a certain distance apart, creating a receiving space between them. The seal can be fitted onto the locking element or frame via this receiving space, allowing parts of the locking element or frame to be positioned within it. Advantageously, the two legs are pre-tensioned towards this receiving space, so that they are pressed against the locking element or frame with a certain holding force. This pre-tension can be provided by the mounting bracket, which can also have a U-shaped cross-section with two legs. The outer leg is the one that comes into contact with the environment and is therefore located on the outside of the seal.The inner leg is accordingly arranged on the inside of the seal and, if possible, does not come into contact with environmental influences or only to a very limited extent due to the sealing lip.

[0046] The mounting area can have an overall U-shaped cross-section, and the sealing lip and the shielding support can be connected to it at the two corners of the U-shaped mounting area, extending in opposite directions to the two legs. The outer leg can thus be located on the side of the sealing lip, and the inner leg can be located on the side of the shielding support. Overall, the seal can therefore have an H-shaped cross-section.

[0047] According to an advantageous embodiment of the invention, one of the legs, in particular the outer leg, has a sealing projection. This sealing projection prevents dust, dirt, water, and possibly even air from entering between the mounting area and the frame, provided the mounting area is attached to the frame. 19.09.2025 Our reference: 25-13-103

[0048] 12, or between the mounting area and the locking element, provided the frame is located on the locking element. The sealing projection can extend into the receiving space and be elastically deformed when the seal is placed on the frame or the locking element. The sealing projection can then seal against the frame or the locking element. The elastic deformation of the sealing projection allows for a surface contact between the sealing projection and the locking element or the frame. The sealing projection can be designed as a sealing lip or a sealing lamella. Advantageously, only a single sealing projection is provided.

[0049] The other, particularly inner, leg can advantageously have several retaining projections. These projections can ensure a reliable hold of the mounting area on the frame or locking element and can be positioned opposite the sealing projection in the receiving space. Advantageously, three retaining projections are provided, allowing for a reliable connection. Similar to the sealing projection, the retaining projections can point into the receiving space, so that the seal can be attached to the frame or locking element with minimal effort, but requires more force to remove.

[0050] The sealing projection can be longer than the retaining projection(s), as the retaining projections do not need to provide a sealing function and therefore line contact with the locking element or the frame is sufficient. The sealing projection and the retaining projections can be part of the casing or monolithically injection-molded onto the casing. Regarding the material of the sealing projection and the retaining projections, please refer to the above. 19.09.2025 Our reference: 25-13-103

[0051] 13

[0052] Furthermore, the leg with the sealing projection can be arranged on the outside. In this way, the sealing projection can exert its sealing effect on the side where the ingress of dust, dirt, or water is likely. Accordingly, this leg can be arranged on the side of the sealing lip. The other leg with the retaining projections can be arranged on the inside, where the shielding support is also located.

[0053] Regarding the arrangement of the shielding element, it has also proven advantageous for it to engage a retaining projection. The shielding element can extend section by section into the receiving space, so that its end is not readily accessible. The shielding element can engage the shielding support, be guided along the inside of the seal, engage one leg of the mounting area, and finally engage the outermost retaining projection at its end. The end of the shielding element can thus be well protected between two retaining projections.

[0054] According to an advantageous embodiment of the invention, the sealing lip and the shielding support are arranged together on one of the two legs. This design expands the range of application of the seal and allows it to be used even when the frame and the locking element are arranged parallel to each other. Depending on the arrangement of the frame and locking element, the sealing lip and the shielding support can be arranged either on the inner leg or the outer leg. The inner leg is the leg facing the interior space to be sealed, and the outer leg is the leg facing away from the interior space. Therefore, the sealing lip and the shielding support can be located on either the leg that has the retaining projections. 19.09.2025 Our reference: 25-13-103

[0055] 14 as well as on the leg which has the sealing projection.

[0056] Furthermore, it has proven advantageous if the sealing lip and the shielding support extend, particularly substantially, transversely to the leg. The sealing lip and the shielding support can be aligned, particularly substantially, parallel to each other and thus extend together away from the respective leg. The sealing lip and the shielding support can also be arranged, particularly substantially, transversely to the frame onto which the seal can be attached. Overall, the sealing lip and the shielding support can be arranged laterally to the mounting area.

[0057] Further details and advantages of the invention will be explained in more detail below with reference to the accompanying illustrations. These illustrate:

[0058] Fig. 1 shows a seal in a cutaway side view;

[0059] Fig. 2 shows a cutaway side view of a frame and a door with a seal according to Fig. 1;

[0060] Fig. 3 shows a further embodiment of a seal in a cutaway side view, in which the sealing lip and the shielding carrier are arranged rotated relative to the mounting area compared to the embodiment of Fig. 1;

[0061] Fig. 4 shows a further embodiment of a seal in a sectional side view, in which the sealing lip and the shielding carrier are arranged rotated to the opposite side compared to the embodiment in Fig. 3. 19.09.2025 Our reference: 25-13-103

[0062] 15

[0063] Figure 1 shows a seal 10 in a sectional side view. Figure 2 shows an installation situation of the seal 10, in which the seal 10 is mounted on a fixed frame 30 and is contacted by a closing element 20, such as a door, in its closed position. The closing element 20 can be opened or closed by a pivoting movement, as can be seen from the direction of movement B illustrated in Figure 2.

[0064] The primary function of the seal 10 is to seal two interconnected spaces against each other. As illustrated in Fig. 2, this means that no dust, dirt, water, or even air can enter the area below the locking element 20 and to the right of the frame 30 from the area above the locking element 20 and to the left of the frame 30. The first area is therefore also referred to as the exterior space, and the other area as the interior space. The seal 10 thus provides an overall seal against environmental influences, as these cannot pass through the area between the frame 30 and the seal 10, nor between the locking element 20 and the seal 10.

[0065] The side of the seal 10 facing the interior is referred to as the inside 10.1 of the seal 10, and the other side accordingly as the outside 10.2. Environmental influences can therefore only come into contact with the outside 10.2 of the seal 10; contact with the inside 10.1 is reliably prevented by the seal 10 itself.

[0066] Besides its purely sealing function, the illustrated seal 10 also fulfills another purpose. It can shield or significantly attenuate electromagnetic radiation. This means that 19.09.2025 Our reference: 25-13-103

[0067] 16. Electromagnetic radiation cannot pass through the gap between the frame 30 and the locking element 20 due to the seal 10, or only to a very small extent, essentially analogous to the aforementioned environmental influences. For appropriate shielding, the seal 10 is equipped with a shield 3, which essentially consists of a shielding carrier 3.1 and a shielding element 3.2, as will be explained in more detail below.

[0068] Overall, the seal 10 essentially consists of three different sections or areas: the sealing lip 1, the shield 3, and the mounting area 2, via which the seal 10 is arranged on the frame 30 in the exemplary embodiment. Alternatively, the seal 10 can also be arranged on or attached to the locking element 20.

[0069] The mounting area 2 initially comprises a substantially U-shaped mounting bracket 2.4, which is arranged inside the mounting area 2 and is circumferentially encased by the sheathing 2.5, so that the mounting bracket 2.4 is not visible from the outside. The mounting bracket 2.4 is made of spring steel and the sheathing 2.5 of soft rubber, so that only the rubber, but not the steel, comes into contact with the frame 30.

[0070] Overall, the mounting area 2 also has a U-shaped cross-section. This is essentially formed by the two legs 2.1, 2.2, between which a receiving space 2.3 is arranged. The seal 10 can now be attached to the frame 30 via the mounting area 2, as can be seen in the illustration of Fig. 2. The two legs 2.1, 2.2 can be pre-tensioned in the direction of the receiving space 2.3, so that they are slightly elastically deformed outwards when attached to the frame 30. Due to the material residual stress of the mounting bracket 2.4, the two legs 2.1, 2.2 exert a force. 19.09.2025 Our reference: 25-13-103

[0071] 17 on both sides of the frame 30, which ensures a reliable connection between seal 10 and frame 30.

[0072] As can be seen in Fig. 1, the two legs 2.1, 2.2 are not symmetrical. The outer leg 2.1 has a sealing projection 2.11 on its side facing the receiving space 2.3, while the inner leg 2.2 has three retaining projections 2.21 opposite this. The sealing projection 2.11 is flexible and, when the seal 10 is placed on the frame 30, it bends upwards so that it rests against the outside of the frame 30. Thus, the area between the seal 10 and the frame 30 is reliably sealed by the sealing lip 1. The elastic deformation of the sealing projection 2.11 is not shown in Fig. 2. However, one can also imagine, based on the illustration in Fig. 1, how the sealing projection 2.11 is bent upwards by the frame 30 inserted into the receiving space 2.3 and seals against the frame 30.

[0073] Both the sealing projection 2.11 and the retaining projections 2.21 are part of the casing 2.5 or are integrally connected to the casing 2.5, so that the elements are made of the same material. The same applies to the mounting bracket 2.4. This, too, is integrally connected to the casing 2.5 via the bend section 3.11, which is explained below, and is therefore also made of the same material. With regard to the manufacture of the seal 10, all components can thus be injection-molded onto the mounting bracket 2.4 either in one or in several process steps.

[0074] The retaining projections 2.21 are located on the inside 10.1 and therefore do not serve as a seal, but rather to improve the connection between the seal 10 and the frame 30. Accordingly, the 19.09.2025 Our reference: 25-13-103

[0075] 18

[0076] The retaining projections 2.21 are also inclined in such a way that the seal 10 can be easily placed on the frame 30; however, when the seal 10 is pulled off the frame 30, the retaining projections 2.21 cause a tilting and thus a comparatively secure hold of the seal 10.

[0077] Opposite the two legs 2.1, 2.2, the sealing lip 1 and the shielding carrier 3.1 are arranged, so that the overall cross-section of the seal 10 is somewhat reminiscent of an H. The sealing lip 1 consists of an open-pore rubber and is not manufactured as a solid material, but as a hollow chamber sealing lip. This means that the sealing lip 1 has a cavity inside, which, in combination with the open-pore material, results in very good flexibility. Such hollow sealing lips 1 are sometimes also referred to as sealing lip balloons.

[0078] The shielding support 3.1 is arranged at a distance from the sealing lip 1. It is significantly more compact than the sealing lip 1 and has a cross-sectional geometry more like a cone or rod, meaning it is considerably longer than it is wide. Furthermore, the shielding support 3.1 is made of soft rubber, a material without open pores, and it has no internal cavity; it is made of solid material. Overall, the shielding support 3.1 therefore exhibits significantly higher stability than the sealing lip 1.

[0079] In addition to its primary function as a support for the shielding element 3.2 (which will be explained in more detail below), the shielding support 3.1 also acts as a stop for the closing element 20. This is also evident from the illustration in Fig. 2. When the closing element 20 is closed and moved towards the frame 30, it comes into contact with both the sealing lip 1 and the shielding support 3.1. The sealing lip 1 is elastically deformed in the process. [19.09.2025 Our reference: 25-13-103]

[0080] 19 then adheres to the inside of the closing element 20 in a flat manner in order to achieve a sealing effect.

[0081] The shielding support 3.1 prevents excessive deformation of the sealing lip 1, which is a particular concern when the locking element 20 is closed at high speed. While the shielding support 3.1 can also deform elastically to some extent when the locking element 20 closes, it is significantly more stable than the sealing lip 1. Furthermore, the shielding support 3.1 is connected to the mounting area 2 via a bending section 3.11, which allows for a certain degree of spring-like movement of the shielding support 3.1 when the locking element 20 closes. The bending section 3.11 has a smaller cross-section than the shielding support 3.1 but is also made of soft rubber, allowing the shielding support 3.1 to move around the bending section 3.11, or around the point where it connects to the mounting area 2.

[0082] Overall, the shielding support 3.1 also ensures that the forces acting on the locking element 20 are kept within manageable limits, unlike if the locking element 20 were to run against a fixed and inelastic stop, for example. Therefore, the sealing lip 1 and the shielding support 3.1 are also approximately the same height.

[0083] To achieve the aforementioned shielding effect, a shielding element 3.2, designed as a shielding foil, is provided, which is shown as a dashed line in Figures 1 and 2. To achieve the necessary shielding, it is important that the shielding foil or shielding element 3.2 makes contact with the locking element 20 and the frame 30 and electrically connects these two elements. The shielding element 3.2 is positioned in the closed 19.09.2025 Our reference: 25-13-103

[0084] 20

[0085] The position is contacted by both the locking element 20 and the frame 30, as can be seen in Fig. 2. Furthermore, the shielding element 3.2 is made of an electrically conductive material, thus enabling an electrical connection. This is because the sheathing 2.5, as well as the sealing lip 1 and the shielding support 3.1, are not electrically conductive.

[0086] The shielding element 3.2 is now guided around the shielding support 3.1 in its upper region, or the shielding support 3.1 encompasses the shielding support 3.1, as can also be seen in the illustration of Fig. 1. The shielding support 3.1 has a rounded section in its upper region, with which the closing element 20 makes contact in the closed position. The shielding element 3.2 is guided around this rounded section, so that the closing element 20 then rests against the shielding element 3.2 in the closed position.

[0087] Furthermore, the shielding element 3.2 extends downwards along the inner side 10.1 of the seal 10 to the area of ​​the mounting area 2. Here, the shielding element 3.2 is guided around the inner leg 2.2 so that it reaches the area that is in contact with the frame 30. The shielding element 3.2 also encompasses the lowest of the three retaining projections 2.21, which ensures reliable electrical contact with the frame 30.

[0088] The discharge element 3.2 is glued to the shielding carrier 3.1 and to the mounting area 2. To ensure that the shielding element 3.2 and the adhesive layer last as long as possible, the ends of the shielding element 3.2 are not easily accessible from the outside, and there is no risk of the ends of the shielding element 3.2 being accidentally pulled off. For this purpose, the shielding element 3.2 extends quite far towards the mounting area 2 on the side of the shielding carrier 3.1 facing the sealing lip 1. This ensures that the contact surface between the shielding element 3.2 and the mounting area 2 is sufficiently large. 19.09.2025 Our reference: 25-13-103

[0089] 21 and the shielding carrier 3.1 are quite large, and in addition, the end of the shielding element 3.2 is located in the protected interior between the shielding carrier 3.1 and the sealing lip 1.

[0090] On the opposite side, the end of the shielding element 3.2 lies between the two lower retaining projections 2.21, so that this end is also quite well protected, especially since the frame 30 reliably prevents unintentional contact with the end of the shielding element 3.2 anyway. Thus, it can be ensured that the adhesive bond of the shielding element 3.2 lasts as long as possible.

[0091] Furthermore, the shielding element 3.2 is also positioned behind the sealing lip 1 to protect it from environmental influences, as can be seen in Fig. 2. The sealing lip 1 thus prevents the ingress of dirt, dust, or moisture before it reaches the shielding element 3.2. This also improves the adhesion of the shielding element 3.2 and eliminates the risk of the adhesive layer of the shielding element 3.2 detaching after a relatively short time.

[0092] Figures 3 and 4 show further embodiments of the invention in which the sealing lip 1 and the shielding carrier 3.1 are arranged rotated, unlike the embodiments shown in Figures 1 and 2. Figure 3 shows an embodiment in which the sealing lip 1 and the shielding carrier 3.1 are arranged rotated 90 degrees counterclockwise, and Figure 4 shows an embodiment in which the sealing lip 1 and the shielding carrier 3.1 are arranged rotated 90 degrees clockwise. Overall, only the orientation of the sealing lip 1 and the shielding carrier 3.1 has changed compared to the embodiments shown in Figures 1 and 2, so reference is made to the preceding description regarding the remaining design of the seal 10. 19.09.2025 Our reference: 25-13-103

[0093] 22

[0094] In the illustration of Fig. 3, the seal 10 can also be seen in a position mounted on a frame 30. The seal 10 is attached to the frame 30 via the mounting area 2; however, contrary to the illustration in Fig. 2, the locking element 20 no longer extends transversely to the frame 30, but parallel to it. The seals 1 shown in the illustrations of Figs. 3 and 4 can therefore be used to seal a frame 30 against a locking element 20, provided they are arranged parallel to each other.

[0095] In the illustration of Fig. 3, the shielding element 3.2 applied to the shielding carrier 3.1 is shown only in abbreviated form; that is, it is only applied to the shielding carrier 3.1 and does not extend around the mounting area 2 to the retaining projection 2.21. However, this is possible, and a corresponding design can sometimes lead to better retention of the shielding element 3.2 due to the larger connection area.

[0096] In the embodiment shown in Fig. 4, the shielding support 3.1 is arranged opposite the retaining projections 2.21 with respect to the leg 2.2, and the shielding element 3.2 extends over the shielding support 3.1 to around the lowest retaining projection 2.21, essentially the same as in the embodiment shown in Figs. 1 and 2. 19.09.2025 Our reference: 25-13-103
