Description

[0001] The present invention relates to an anti-pinch device for a door of a vehicle, to a door system for a vehicle and to a method for producing an anti-pinch device for a door of a vehicle.

[0002] To prevent a person from being trapped and possibly even dragged through a vehicle door, detection options are mostly known in which a sensor, such as a safety edge, is installed after the extrusion of a finger protection profile.

[0003] DE 10 2010 046 632 A1 relates to a sealing strip arrangement for a door with a first, at least partially rubber-elastic profile strip and a second, at least partially rubber-elastic profile strip, wherein at least one of the profile strips has a hollow chamber for receiving an electrical switching strip, wherein the profile strips each have at least one projection, wherein the projections are each connected to the hollow chamber via an actuating web which is connected to the wall of the hollow chamber in the region of the central plane of the hollow chamber.EP 2 532 820 A2 shows a hollow profile for an electrical switching strip, wherein at least one first and one second electrical conductor are provided adjacent to a hollow space of the hollow profile which extends in the longitudinal direction of the elastic hollow profile, wherein for outputting direction-selective switching signals at least one region of the at least one first and / or second conductor which adjoins the hollow space is arranged offset relative to a center plane of the hollow profile in a sectional view perpendicular to the longitudinal direction.

[0004] Against this background, it is the object of the present invention to provide an improved anti-pinch device for a door of a vehicle, an improved door system for a vehicle and an improved method for producing an anti-pinch device for a door of a vehicle.

[0005] This object is achieved by a device for anti-pinch protection for a door for a vehicle, by a door system for a vehicle and by a method for producing a device for anti-pinch protection for a door for a vehicle according to the main claims.

[0006] According to the invention, a switching element is provided for integrated anti-pinch protection or integrated anti-pinch detection, which is extruded with or integrated into an extrusion profile. In contrast to detection options for anti-pinch protection, in which a sensor is installed after the extrusion of a finger protection profile, in the device a switching element can be integrated directly into the extrusion profile or extruded with the extrusion profile. In this case, the extrusion profile can, in particular, have regions of increased rigidity and regions of reduced rigidity as well as a specifically designed geometry in order to be able to reliably detect trapped objects. This can, for example, reduce the probability of a person being trapped or even dragged along by an oncoming vehicle. In particular, reliable detection of wipes can be achieved in this way.

[0007] Advantageously, an integral design can be implemented, which allows for a reduction in the number of components, as several functions, such as anti-pinch protection, anti-pinch detection, and the "pinch pain" are combined in a single component. This results in a simple operating principle thanks to an encapsulated, maintenance-free system that is insensitive to external influences. Evaluation with existing door control systems is possible. A functional failure can be detected, resulting in increased security against vandalism. Furthermore, the device can be easily mounted on a door thanks to a molded mounting bar. Particularly with double-leaf doors, two equivalent safety edges or sensors can be installed on each door leaf using one device.Molded parts can be realized, which both switch at different times and reliably in the event of the required defined events, such as the clamping of a cuboid or other three-dimensional object as well as a cloth, and can thus also reduce the probability of dragging through reliable and timely detection.

[0008] A device according to the invention for anti-pinch protection for a vehicle door has the features of independent claim 1. The vehicle can be, for example, a vehicle for transporting people. In particular, the vehicle can be designed as a rail vehicle. The system can be a door system of the vehicle. The device can also be referred to as a finger protection strip. The features of the extruded profile can be extruded continuously. The door leaf wall and the sealing wall can have mutually parallel or approximately parallel extension planes. The extruded profile can have an extrusion axis that can extend along the extension planes and normal to the transverse axis. The switching element can comprise an electrically conductive material and at least two electrical conductors.Alternatively, but not according to the invention, the switching element can have at least one optical fiber or other devices suitable for detecting the compression. According to the invention, the switching plunger is designed so that, upon contact with a clamped object, it can be set into a movement with at least one movement component along the transverse axis and additionally or alternatively with at least one movement component transverse to the transverse axis. The compression force can be transmitted to the switching element via the switching plunger. The switching plunger can extend over its entire length or in sections along the transverse axis. According to the invention, the at least one switching element is integrated into the extrusion profile and can thus be extruded with the extrusion profile and cut to length.

[0009] According to one embodiment, the device can have a mounting web. The mounting web can extend along the transverse axis of the extrusion profile. The door leaf wall and the sealing wall can be connected to one another via the mounting web. The mounting web can be offset relative to the switching tappet along a plane of extension of the sealing wall. The mounting web can be aligned normally with respect to the planes of extension. The mounting web can extend along its entire length or in sections along the transverse axis. Between the door leaf wall and the sealing wall, the extrusion profile can have a cavity which can be divided into at least two chambers, at least by the mounting web. Such an embodiment offers the advantage that the rigidity of the extrusion profile can be increased and, when the device is mounted on the door, a flow of force can be diverted past the switching element.

[0010] Alternatively, the extrusion profile can be formed as a solid profile. A volume of the extrusion profile between the door leaf wall and the sealing wall can be completely or at least partially made of the elastomer material. Such a design offers the advantage of increasing the rigidity of the extrusion profile and allowing force flow to be bypassed by the switching element when the device is mounted on the door.

[0011] According to the invention, the switching element has a first electrically conductive section and a second electrically conductive section, which are separated from one another by an intermediate space compressible by the compression force. Each electrically conductive section can comprise an electrically conductive material and at least one electrical conductor. Such an embodiment offers the advantage that the compression can be detected in a simple and reliable manner. The first section can be arranged on the sealing wall in the region of the switching tappet, facing the door leaf wall. The second section can be arranged between the first section and the door leaf wall with respect to the transverse axis. Alternatively, the intermediate space compressible by the compression force can extend along the transverse axis.Such a design offers the advantage that the electrically conductive sections can be shaped to suit the requirements. This can ensure, for example, that the switching element only switches when a force acts on the switching plunger in a predefined direction.

[0012] The second section of the switching element can also be arranged on a partition wall or as a partial section of a partition wall between the sealing wall and the door leaf wall. The partition wall can be connected to the mounting web and the sealing wall. Such a design offers the advantage that even compression triggered by low compression forces can be reliably detected.

[0013] Furthermore, a ratio of a dimension of the switching plunger along the transverse axis to a dimension of the first section of the switching element along the transverse axis can have a predefined value. Such an embodiment offers the advantage that the sensitivity of compression detection can be adjusted during manufacture depending on the intended application of the device.

[0014] According to one embodiment, the extruded profile can have a sealing surface and a sealing element. The sealing surface and the sealing element can be connected to the sealing wall and extend away from the door leaf wall. The switching plunger can be arranged between the sealing surface and the sealing element. In other words, the sealing surface and the sealing element can be formed as protrusions that extend away from the sealing wall in the direction of the door leaf wall. Such an embodiment offers the advantage that a complementary interaction of the device with another device can be achieved. Furthermore, an advantageous compression tolerance of two devices relative to one another along the transverse direction can be achieved.In a complementary interaction, the sealing surface of a first device and the sealing element of a second device can interact, and the sealing element of the first device and the sealing surface of the second device can interact.

[0015] The sealing surface can have an extension plane that can be parallel to the extension plane of the sealing wall. A dimension of the sealing surface transverse to the transverse axis can be larger than a predefined, permissible offset of the door transverse to the transverse axis relative to a reference object. A transverse alignment can also have an orthogonal alignment. Such an embodiment offers the advantage that reliable sealing of a door gap can be achieved even if a door, and thus a device attached to the door, is offset relative to a desired position.

[0016] In particular, the sealing element can be designed as a sealing lip, a sealing balloon, a double balloon, and additionally or alternatively as a double lip. Such a design offers the advantage of reliably sealing a door gap.

[0017] In this case, an end of the switching plunger facing away from the sealing wall can also have a first distance from the sealing wall. Furthermore, an end of the sealing element facing away from the sealing wall can have a second distance from the sealing wall. In addition, an end of the sealing surface facing away from the sealing wall can have a third distance from the sealing wall. The first distance can be smaller than the second distance and greater than the third distance. Alternatively, the first distance can be greater than the second distance and smaller than the third distance. Alternatively, the first distance, the second distance, and the third distance can be the same within a tolerance range. Such an embodiment offers the advantage that a compression tolerance can at least be maintained even with reliable sealing of a door gap. Furthermore, the distances can be selected as needed.

[0018] According to the invention, the device comprises at least one stiffening element, wherein the stiffening element is integrated into the extrusion profile, and wherein the stiffening element is integrated into the switching plunger and additionally or alternatively into a section of the extrusion profile adjacent to the sealing wall. The stiffening element is designed as a metal wire, metal strip, or the like and functions as a cut protection device, as an anti-vandalism device, or the like. Such an embodiment offers the advantage that reliable protection against damage, deliberate destruction, vandalism, and the like can be easily provided for the device. Thus, pinching detection can still be performed even after a confirmation attempt.The stiffening element can serve to increase the stiffness of at least a partial section of the extrusion profile and can therefore also provide vandalism protection against pressing an object transversely to the transverse axis against the extrusion profile or vandalism protection against actuation of the switching element by pressure with an object transversely to the transverse axis.

[0019] Furthermore, the extrusion profile can have an attachment section for attaching the device to the door. The attachment section can be connected to the door leaf wall and extend along the transverse axis in the direction away from the sealing wall. In particular, the attachment section can be connected to the door leaf wall in the region of the mounting web. In other words, the attachment section and the mounting web can be arranged collinearly. Such an embodiment offers the advantage that the device can be attached to a door in a simple and secure manner, while avoiding compression of the extrusion profile in the region of the at least one switching element.

[0020] A door system for a vehicle has the following features: a door with at least one door leaf, wherein an embodiment of the above-mentioned device is arranged on an abutting edge of at least one door leaf.

[0021] In conjunction with the door system, at least one device, which is an embodiment of the device mentioned above, can advantageously be employed or used to provide anti-pinch protection. A device can be attached directly to a door leaf, to a seal, or to a profile element. If the door is designed with two door leaves, a first device can be arranged on a first door leaf and a second device can be arranged on a second door leaf. The first device and, additionally or alternatively, the second device can be an embodiment of the device mentioned above. The first device can also be shaped differently than the second device.

[0022] According to one embodiment, the door system can also comprise at least one molded part. The molded part can function as a transition between a door seal of a door leaf of the door and the device. The molded part can be connectable or connected to the door leaf, to the door seal, and additionally or alternatively to the device. Such an embodiment offers the advantage that, by means of at least one such molded part, both pressure along the transverse axis of the device and offset transverse to the transverse axis with respect to movement of the door leaves can be reduced or restricted.

[0023] A method according to the invention for producing an anti-pinch device for a door of a vehicle comprises the steps specified in claim 12.

[0024] By carrying out the manufacturing method, an embodiment of the above-mentioned device can be advantageously produced.

[0025] According to one embodiment, the extrusion step and the integration step can be carried out together. The switching element can be extruded with the elastomer material. Such an embodiment offers the advantage of providing an encapsulated, maintenance-free or low-maintenance component that is resistant to harmful external influences. In the integration step, the switching element and, additionally or alternatively, another switching element can be vapor-deposited onto the elastomer material. Such an embodiment offers the advantage that switching elements can be formed quickly and easily as needed.

[0027] Fig. 1 shows a schematic representation of a vehicle 100 with a door system 110 according to an exemplary embodiment. According to the exemplary embodiment shown here, the vehicle 100 is a rail vehicle. The door system 110 has a door 112 with, by way of example only, two door leaves 114. Furthermore, the door system 110 has, by way of example only, two devices 120 for anti-pinch protection. Each device 120 is arranged on its own door leaf 114. The devices 120 are arranged on mutually facing abutting edges of the door leaves 114. In other words, a door gap between the two door leaves 114 is sealed by the devices 120 or, among other things, by the devices 120. The device 120 will be discussed in more detail with reference to the figures described below.

[0028] According to one embodiment, the two devices 120 are identically configured and arranged complementarily to one another when the door 112 is closed. According to another embodiment, the devices 120 can be shaped and / or configured differently. In this case, the devices 120 can differ from one another with respect to an extrusion profile and / or a switching element thereof. For example, only one of the devices 120 can have a switching element.

[0029] Fig. 2 shows a flowchart of a method 200 for producing a device for anti-pinch protection for a door for a vehicle according to an embodiment. By executing the method 200, each of the devices from Fig. 1 and / or a device from one of the figures described below. The method 200 comprises an extrusion step 210, an integration step 220, and a cutting step 230.

[0030] In the extrusion step 210, elastomer material is extruded into an extrusion profile. The extrusion profile has a door leaf wall, a sealing wall, and a switching tappet. When the device is mounted on the door, the door leaf wall faces an abutting edge of a door leaf. The sealing wall is arranged opposite the door leaf wall. The door leaf wall and the sealing wall have mutually parallel or approximately parallel extension planes. The switching tappet is designed to transmit a compression force into the extrusion profile. The switching tappet is arranged on the sealing wall and extends away from the door leaf wall along a transverse axis of the extrusion profile.

[0031] In the integration step 220, at least one switching element for detecting compression of the extrusion profile is integrated into the extrusion profile. The at least one switching element is arranged in the region of the switching plunger between the door leaf wall and the switching plunger. Finally, in the cutting step 230, the extrusion profile is cut to the desired length. The switching element is cut to the desired length with the extrusion profile.

[0032] Even if it is in the representation of Fig. 2 Not explicitly shown, according to one embodiment, the extrusion step 210 and the integration step 220 are performed jointly. The switching element is extruded with the elastomer material. Optionally, in the integration step 220, the switching element and / or another switching element is vapor-deposited onto the elastomer material.

[0033] Fig. 3 shows a schematic representation of a device 120 for anti-pinch protection according to an exemplary embodiment. The device 120 is designed to enable anti-pinch protection for a door of a vehicle. The device 120 can be used or employed in connection with the door, the door system, or the vehicle, as described in Fig. 1 In other words, any Fig. 1 device shown in Fig. 3 correspond to or are similar to the device 120 shown.

[0034] The device 120 comprises an extrusion profile 330 and at least one switching element 350. The extrusion profile 330 is extruded in one piece from the elastomer material. The at least one switching element 350 is integrated into the extrusion profile 330 extruded from the elastomer material or is extruded and cut to length together with the extrusion profile 330. For orientation, Fig. 3 also an x-axis, a y-axis and a z-axis of a three-dimensional coordinate system are specified. An extrusion axis, along which the extrusion profile 330 is extruded or which represents a longitudinal axis of the device 120, corresponds to the z-axis in the representation of Fig. 3 .

[0035] The extruded profile 330 has a door leaf wall 332, a sealing wall 334, a mounting web 336, and a switching tappet 338. When the device 120 is mounted on the door of the vehicle, the door leaf wall 332 faces an abutting edge of a door leaf. The sealing wall 334 is arranged opposite the door leaf wall 332. The door leaf wall 332 and the sealing wall 334 have mutually parallel extension planes. An intermediate space or cavity with at least two chambers is arranged between the door leaf wall 332 and the sealing wall 334. The extension planes of the door leaf wall 332 and the sealing wall 334 are spanned or defined by the y-axis and the z-axis. According to one embodiment, the extension planes of the door leaf wall 332 and the sealing wall 334 are at least partially parallel or approximately parallel to each other.The extension planes of the door leaf wall 332 and the sealing wall 334 can also be aligned obliquely to each other in sections or completely.

[0036] The mounting web 336 represents a section of the extrusion profile 330 for increasing a stiffness of the extrusion profile 330. The mounting web 336 extends normal with respect to the extension planes along a transverse axis of the extrusion profile 330. The transverse axis corresponds to the x-axis in Fig. 3 The door leaf wall 332 and the sealing wall 334 are connected to each other via the mounting web 336. The mounting web 336 also divides the cavity between the door leaf wall 332 and the sealing wall 334 into two chambers. According to one embodiment, the mounting web 336 extends obliquely to the transverse axis.

[0037] The switching plunger 338 is arranged on the sealing wall 334 and extends along the transverse axis or x-axis in the direction away from the door leaf wall 332. Furthermore, the switching plunger 338 is arranged offset relative to the mounting web 336 along the plane of extension of the sealing wall 334. In other words, the mounting web 336 and the switching plunger 338 are connected to adjacent sections on different sides of the sealing wall 334. The switching plunger 338 is designed to transmit a compression force into the extrusion profile 320 and to the switching element 350.

[0038] According to the Fig. 3 In the illustrated embodiment, the device 120 has, for example, only one switching element 350. The switching element 350 is arranged in the region of the switching plunger 338 between the door leaf wall 332 and the switching plunger 338. A partial section of the sealing wall 334 is arranged between the switching plunger 338 and the switching element 350. The switching element 350 is designed to detect a compression of the extrusion profile 330 transmitted into the extrusion profile 330 by the switching plunger 338.

[0039] The switching element 350 has, according to the Fig. 3 In the embodiment shown and described, the first electrically conductive section 352 has a first electrical conductor 354 and a second electrically conductive section 356 with a second electrical conductor 358. The first section 352 and the second section 356 are separated from one another by a space compressible by the compression force. The first electrical conductor 354 is embedded in the first section 352. The second electrical conductor 358 is embedded in the second section 356. The first section 352 and the second section 356 are formed or extruded from an electrically conductive material.

[0040] The first section 352 is arranged on the sealing wall 334. More precisely, the first section 352 is arranged in the region of the switching tappet 338 on a side of the sealing wall 334 facing the door leaf wall 332. The second section 356 is arranged between the first section 352 and the door leaf wall 332 with respect to the transverse axis or x-axis. More precisely, the second section 356, according to the exemplary embodiment shown here, is designed or formed on an intermediate wall 342 or as a partial section of an intermediate wall 342 between the sealing wall 334 and the door leaf wall 332. The intermediate wall 342 extends between the mounting web 336 and the sealing wall 334. The intermediate wall 342 is also connected to the mounting web 336 and to the sealing wall 334.

[0041] The extrusion profile 330 also has the Fig. 3 In the exemplary embodiment shown, the door leaf 332 has a sealing surface 344 and a sealing element 346. The sealing surface 344 and the sealing element 346 are connected to the sealing wall 334 and extend on a side of the sealing wall 334 facing away from the door leaf wall 332 in the direction away from the door leaf wall 332. The switching plunger 338 is arranged between the sealing element 346 and the sealing surface 344 with respect to the plane of extension of the sealing wall 334. The sealing surface 344 has a plane of extension that is parallel to the plane of extension of the sealing wall 334 and / or parallel to the plane of extension of the door leaf wall 332. The sealing element 346 is formed as a sealing lip. Thus, the sealing surface 344 and the sealing element 346 are designed as projecting sections of the extrusion profile 330 relative to the sealing wall 334. According to one embodiment, the sealing wall 334 has a bend towards the sealing surface 344.The sealing element 346 is, for example, S-shaped.

[0042] According to the Fig. 3 In the illustrated embodiment, an end of the switching plunger 338 facing away from the sealing wall 334 is arranged at a first distance from the sealing wall 334, an end of the sealing element 346 facing away from the sealing wall 334 is arranged at a second distance from the sealing wall 334, and an end of the sealing surface 344 facing away from the sealing wall 334 is arranged at a third distance from the sealing wall 334. The first distance is smaller than the second distance and greater than the third distance. Thus, the sealing element 346 protrudes the furthest away from the sealing wall 334. The sealing surface 344 protrudes the least far from the sealing wall 334. In this way, an advantageous pressing tolerance of the extrusion profile 330 or of the device 120 along the transverse axis or x-axis can be achieved.

[0043] The extrusion profile 330 has, according to the Fig. 3 In the exemplary embodiment shown and described, the device 120 further comprises an attachment section 348. By means of the attachment section 348, the device 120 can be attached to the door of the vehicle. The attachment section 348 is connected to the door leaf wall 332 in the region of the mounting web 336. The attachment section 348 extends on a side of the door leaf wall 332 facing away from the sealing wall 334 along the transverse axis or x-axis in the direction away from the sealing wall 334. Thus, a partial section of the door leaf wall 332 is arranged between the mounting web 336 and the attachment section 348. The attachment section 348 has a mushroom-shaped cross-section.

[0044] As in Fig. 3 As shown, the device 120 has a cut protection device 360. The cut protection device 360 ​​is designed as a metal wire, metal rod, or the like. According to the exemplary embodiment shown here, the cut protection device 360 ​​is integrated or embedded in the switching plunger 338.

[0045] In other words, Fig. 3 a cross-section of the device 120 and thus of the extrusion profile 330 with the switching element 350 for the integrated detection of jammed objects. After extrusion, the resulting continuous material is to be cut to the desired length as required, and electrical, and if necessary optical, connections for the switching element 350 are to be attached. The elastomer, e.g., EPDM or silicone, should meet defined fire protection requirements (e.g., EN45545). A co-extruded electrically conductive material of sections 352 and 356 of the switching element 350 can comprise, among other things, the following electrically conductive materials: elastomers, e.g., EPDM or silicone, or elastomers, e.g., EPDM or silicone, in combination with metal wires. Alternatively, an electrical conductor or a reflector, for example, can also be applied as the switching element 350 in a further manufacturing process step, for example by vapor deposition.As a further alternative, instead of electrically conductive strips, an optical fiber or a reflector, a switching strip, or a strip switch can be co-extruded or subsequently incorporated into the extrusion profile 330. The mounting web 336 is shaped to direct the effect of force when mounting the device 120 on a door in such a way that the force flow is redirected or guided past the switching element 338. The increased rigidity provided by the mounting web 336 facilitates both mounting on a door leaf and the function of safety devices, for example, obstacle detection or the like.

[0046] According to one embodiment, the extrusion profile 330 has a first outer wall 370 and a second outer wall 372. The first outer wall 370 connects first ends of the door leaf wall 332 and the sealing wall 334. The second outer wall 372 connects second ends of the door leaf wall 332 and the sealing wall 334. The mounting web 336 is arranged longitudinally to the first outer wall 370 and the second outer wall 372. The mounting web 336 is arranged in a middle third of a distance between the first outer wall 370 and the second outer wall 372. For example, the mounting web 336 is arranged centrally between the first outer wall 370 and the second outer wall 372.

[0047] Fig. 4 shows a schematic representation of a device 120 for anti-pinch protection according to an embodiment. The device 120 corresponds to or is similar to the device from Fig. 1 or Fig. 3 . Here, the device 120 is shown in a perspective view. In the illustration of Fig. 4 The extrusion profile 330, of which the attachment section 348 is explicitly designated, and the switching element 350 are shown from the device 120. A terminating resistor 455 and a plug 470 are also shown.

[0048] The terminating resistor 455 is attached to the switching element 350. The terminating resistor 455 can enable functional monitoring of the switching element 350 or the device 120. A line break in the switching element 350 or an integrated electrical switching strip can be detected using the closed-circuit current principle. The terminating resistor 455 can be used for this purpose. Subsequently, the device 120 can be encapsulated at at least one end by means of the plug 470, for example to prevent the ingress of moisture. The plug 470 can, for example, be glued or injection-molded. The plug 470 can also be an injection-molded part. Fig. 20 referred to.

[0049] Fig. 5 shows a schematic representation of devices 120 according to an embodiment. Two devices 120 are shown, each device corresponding to or similar to one of the devices shown and described above. The devices 120 are as in the door system of Fig. 1 When the door is closed, they are arranged adjacent to one another. A complementary arrangement of the devices 120 relative to one another can be seen. The sealing element of a first device 120 and the sealing surface of a second device 120 are in contact with one another, with the sealing surface of the first device 120 and the sealing element of the second device 120 being in contact with one another.

[0050] Furthermore, Fig. 5 Dimensions and tolerances for a position of the devices 120 relative to one another in a closed, locked state of a double-leaf entry door are also shown. A nominal rubber width A extends from the door leaf wall of the first device 120 to the door leaf wall of the second device 120. The nominal rubber width A is, for example, 30 to 100 millimeters. A finger protection rubber width B or door leaf width B represents a dimension of the devices 120 along the y-axis in the extension planes of the door leaf wall or the sealing wall. The finger protection rubber width B is, for example, 20 to 50 millimeters. A compression tolerance Δx in the x-direction represents a permissible position of the two devices 120 relative to one another. The compression tolerance Δx is, for example, less than 10 millimeters. The switching element of each device 120 is offset from the mounting web by an offset distance n transverse to the x-axis.The offset distance n, for example, is a maximum of 10 millimeters.

For double-leaf synchronized doors, the doors and thus the devices 120 meet at an entry angle α of zero degrees or α = 0°. For single-leaf doors or double-leaf asynchronous doors, the entry angle α is between 0° < α ≤ 85° or 0° > α ≥ -85°.

[0056] With regard to possible loads on the devices 120, it should be noted that pressure or water tightness for resistance to false triggering of the switching elements of the devices 120, particularly in the case of aerodynamic pressure loads in the rail vehicle sector, is between 0.5 and 10 kPa or kilopascals.

[0060] Fig. 13 shows a schematic representation of a section of a device 120 according to an embodiment. The representation in Fig. 13 the representation from Fig. 10, Fig. 11 or Fig. 12 except that the sealing element 346 is shaped as a sealing balloon with a double lip.

[0061] Fig. 14 shows a schematic representation of devices 120 according to an embodiment. The devices 120 correspond to the devices from one of the Figuren 5 bis 9 , wherein between the devices 120 in the illustration of Fig. 14 a test body 1410, more precisely a rigid test body 1410, is arranged. The test body 1410 is clamped between the devices 120 and is in contact with the switching plungers 338 of the devices 120. Due to the presence of the test body 1410 between the devices 120, a force F or compression force F acts on each switching plunger 338.

[0062] Thus, in Fig. 14 In other words, a pinch protection device is illustrated. For rigid test specimens 1401, the switching plunger 338 is pressed with the force F. Rigid test specimens 1401, for example, with dimensions of 10x50 mm, 30x60 mm, or the like, are detected using the devices 120 even before a door system reaches a closed position.

[0063] Fig. 15 shows a schematic representation of devices 120 according to an embodiment. The representation in Fig. 15 corresponds to the representation from Fig. 14 with the exception that a test cloth 1501 or an elastic test body 1501 is clamped between the devices 120. When the test cloth 1501 is tightened, a force F or compression force F acts on each switching plunger 338.

[0064] Thus, in Fig. 15 In other words, a pinch detection is illustrated. Elastic test specimens 1501, such as a cloth, are detected in the closed position of a door system by pulling them with a force F of, for example, up to 150 Newtons and at a pulling angle β of 0°<β<180°. When elastic test specimens 1501 are pulled, the switching plunger 338 is rotated under the action of the force F. In other words, when elastic test specimens 1501 are pulled, the force F causes the switching plunger 338 to exhibit a movement component along the y-axis.

The first dimension a represents a dimension of the first section 352 of the switching element 350 along the transverse axis of the device 120. Alternatively, the first dimension a represents a dimension of the first section 352 of the switching element 350 and of the switching plunger 338 along the transverse axis on a side of the sealing wall 334 facing the door leaf wall. The second dimension b represents a dimension of the switching plunger 338 along the transverse axis of the device 120 on a side of the sealing wall 334 facing away from the door leaf wall. Alternatively, the second dimension b represents a dimension of the switching plunger 338. A ratio of the two dimensions a and b to one another has a predefined value.

[0067] In other words, in Fig. 16 a transmission ratio of the switching plunger 338 is illustrated. The switching plunger 338 and surrounding sections of the device 120, as well as the switching element 350, can be shaped such that a travel or deformation of the switching plunger 338 and the switching element 350 is provided with a suitable transmission ratio, so that a sensitivity of the switching element 350 can be controlled or a response behavior of the pinch detection can be adjusted. By changing a transmission ratio or the ratio between the dimensions a / b, the sensitivity of the switching element 350 can be adjusted as required, with a constant gap between the electrically conductive sections 352 and 356.

[0068] Fig. 17 shows a schematic representation of a section of a device 120 according to an embodiment.

More specifically, the cut protection device 360 ​​is integrated into a side wall between the sealing wall 334 and the door leaf wall 332 and adjacent to the sealing element 346.

[0071] With reference in particular to the Figuren 18 und 19 It should be noted that the cut protection device 360 ​​can be used as vandalism protection or for vandalism security, e.g. in the event that an attempt is made to damage or cut through the device 120 and in particular the switching element using a knife, so that a pinch detection function can be retained by means of the cut protection device 360.

[0072] Fig. 20 shows a schematic representation of molded parts 2000 according to an embodiment. The molded parts 2000 are for the door system made of Fig. 1 or a similar door system.

The wedge surfaces 2204 or run-up wedges 2204 are shaped to reduce a y-offset Δy or offset along the y-axis.

[0076] In other words, to reduce a lateral offset or the y-offset Δy, a ramp wedge 2204 is integrated into each molded part 2000 to create a positive connection between the molded parts 2000. To reduce rubber abrasion, a metal insert can be arranged on each wedge surface 2204. The ramp wedges 2204 can be arranged at the top and / or bottom of the molded parts 2000.

[0077] Fig. 23 shows a schematic representation of molded parts 2000 according to an embodiment. The representation in Fig. 23 corresponds to the representation from Fig. 22 except that the mold parts 2000 are offset relative to each other in opposite directions along the y-axis.

[0079] Fig. 24 shows a schematic representation of a device 120 according to an embodiment. The device 120 corresponds to the device from one of the Figuren 3 , 5 bis 10 and 14 bis 19 except that the device 120 in Fig. 24 has an extrusion profile 330 formed as a solid profile. This eliminates the need for a mounting bridge and a partition wall.

[0080] The extrusion profile 330 is filled with the elastomer material between the door leaf wall 332 and the sealing wall 334, as well as between the first side wall 370 and the second side wall 372, with the exception of the space between the first electrically conductive section 352 and the second electrically conductive section 356 of the switching element. Here, too, force transmission can be bypassed during assembly.

The first section 352 and the second section 356 of the switching element 350 are also arranged between the mounting web 336 and the switching plunger 338 with respect to the axis y running transversely relative to the transverse axis x.

[0083] Thus, the switching element 350 can be triggered in response to a compression force upon movement of the switching plunger 338 along the axis y extending transversely relative to the transverse axis x.

[0084] Fig. 26 shows a schematic representation of a device 120 according to an embodiment.

[0085] More specifically, the second section 356 is arranged in a smaller portion of the intermediate wall 342 than in the devices of the aforementioned figures. According to another embodiment, the sections 352 and 356 of the switching element can be shaped as required. According to one embodiment, the switching element is configured to switch or be triggered only when a compression force along the transverse axis x acts on the switching plunger 338.

[0086] Fig. 27 shows a schematic representation of a device 120 according to an embodiment. The device 120 corresponds to the device from one of the Figuren 3 , 5 to 10 and 14 to 19 .

The finger is arranged adjacent to the first side wall 370 and the sealing element 346. In this case, the switching plunger 338 would simply be rotated.

[0087] Detection of such a case of vandalism by the switching element 350 is not provided here. However, the device 120 offers vandalism protection against an object being pushed onto the device 120 along the y-axis, which runs transversely relative to the x-axis.

[0088] Fig. 28 shows a schematic representation of a device 120 according to an embodiment. The device 120 corresponds to the device of Fig. 25, wherein in the illustration two directional arrows are added for a force F1 acting on the switching plunger 338 in a first direction along the axis y running transversely relative to the transverse axis x and a force F2 acting on the switching plunger 338 in a second direction along the axis y running transversely relative to the transverse axis x.

[0089] According to the exemplary embodiment presented here, the switching element 350 is designed to switch or be triggered when the force F1 acts on the switching plunger 338 in the first direction along the axis y running transversely relative to the transverse axis x. The first electrically conductive section 352 and the second electrically conductive section 356 of the switching element 350 come into contact with one another. More precisely, the switching element 350 is designed to switch only when the force F1 acts on the switching plunger 338 in the first direction along the axis y running transversely relative to the transverse axis x. The force F2 in the second direction along the axis y running transversely relative to the transverse axis x causes the first section 352 and the second section 356 of the switching element 350 to move away from one another.

[0090] Fig. 29shows a schematic representation of a device 120 according to an embodiment. The device 120 is similar to the device from one of the figures described above, with the exception that the switching element 350, in addition to the first electrically conductive section 352 and the second electrically conductive section 356, also has a further electrically conductive section 2956 with a further electrical conductor 2958. Furthermore, two directional arrows are shown for a force F1 acting on the switching plunger 338 in a first direction along the axis y running transversely relative to the transverse axis x, and a force F2 acting on the switching plunger 338 in a second direction along the axis y running transversely relative to the transverse axis x.

[0091] The further section 2956 is arranged adjacent to the second section 356. The further section 2956 is electrically separated or insulated from the second section 356. More precisely, the further section 2956 and the second section 356 are arranged at a distance from one another along the axis y, which runs transversely relative to the transverse axis x. The first section 352 and the second section 356 are separated from one another by a gap that can be compressed in the first direction by the force F1. The first section 352 and the further section 2956 are separated from one another by a gap that can be compressed in the second direction by the force F2.

[0092] When force F1 acts on switching plunger 338 in the first direction along axis y, which runs transversely relative to the transverse axis x, the first section 352 and the second section 356 of switching element 350 come into contact with one another. When force F2 acts on switching plunger 338 in the second direction along axis y, which runs transversely relative to the transverse axis x, the first section 352 and the further section 356 of switching element 350 come into contact with one another. With appropriate wiring and evaluation, information can be obtained as to whether, when an object becomes trapped in a door gap during withdrawal, a force acts from the outside or from the inside of the vehicle, or a force F1 acts in the first direction or a force F2 acts in the second direction.
