Description

TECHNICAL FIELD

[0001] The present application relates to a method for providing anti-trapping protection for a motor vehicle. BACKGROUND

[0002] A switch strip, in particular as anti-trapping protection for a motor vehicle, is known from DE 102 05 028 739 B3. The switch strip can be used in the region of a window pane which can be raised and lowered in a motor vehicle and serves as a protection device against objects or body parts being trapped during the closing of the window pane. Here, the switch strip can be integrated in a seal which is fastened to the door frame. SUMMARY

[0003] It is the task of the present application to propose a method for providing anti-trapping protection for a motor vehicle which enables two interior components of the motor vehicle to be moved relative to one another in a particularly safe manner.

[0004] The present application relates to a method for providing anti-trapping protection for a motor vehicle. In the method, a micro switch strip is arranged on a first interior component, which micro switch strip can be moved relative to a second interior component automatically by means of a control device. When the micro switch strip is actuated, the movement of the interior components relative to one another is blocked by means of the control device. In other words, when the control device receives a start signal which characterizes a movement command, the control device moves the first interior component of the motor vehicle in the interior space of the motor vehicle relative to the second interior component of the motor vehicle automatically. If the control device receives a stop signal from the micro switch strip arranged on one of the interior components, which stop signal characterizes the actuation of the micro switch strip, the movement of the interior components relative to one another is blocked by means of the control device. Thus, by means of the micro switch strip, anti-trapping protection can be provided in the interior space of the motor vehicle. As a result, a collision between two interior components which can be moved relative to one another can be determined by means of the micro switch strip. In the event of a collision being determined, the automatic relative movement of the interior components relative to one another can be blocked. As a result, injuries to vehicle occupants and / or damage to elements which are trapped between the interior components which can be moved relative to one another can be prevented. The micro switch strip enables anti-trapping protection to be provided for the interior space of the motor vehicle in a particularly simple, safe and cost-advantageous manner.

[0005] In another embodiment of the application it has proven advantageous to arrange the microswitch strip on the outer side of the first inner member facing the second inner member. This is particularly advantageous when the first inner member is moved towards the second inner member. In particular, the microswitch strip is arranged on the first inner member farthest in the direction of movement of the first inner member towards the second inner member. When the first inner member is moved in the direction of the second inner member, the microswitch strip will first come into contact with the second inner member and only thereafter the first inner member comes into contact with the second inner member. Thereby, it can advantageously be avoided that a vehicle occupant and / or an element is pinched between the inner members.

[0006] In another embodiment of the application, the microswitch strip is arranged on an electrically lowerable sunblind and / or an electrically adjustable luggage compartment blind and / or an electrically adjustable rear window blind and / or an electrically adjustable side window blind and / or an electrically adjustable roof window blind and / or an electrically adjustable seat device and / or an electrically adjustable panorama screen device as a first interior component. In the case of a respective blind in the interior space of a motor vehicle, in particular, it is provided that the blind moves relative to a second interior component, which can be, in particular, a decorative element of the interior space of the motor vehicle. Here, it must be ensured that the blind only moves until it comes to rest against the second interior component, whereupon further relative movement of the blind relative to the second interior component is prevented. When the first interior component comes to rest against the second interior component, the microswitch strip is clamped between the first interior component and the second interior component, so that further movement of the blind relative to the decorative element is prevented by means of the control device. In particular, the blind is moved particularly frequently in the interior space of the motor vehicle, wherein the microswitch strip provides particularly reliable anti-trapping protection together with a particularly high service life. Thus, the microswitch strip ensures that the blind cannot be damaged as a result of the movement of the blind towards the second interior component when the blind is moved relative to the second interior component. Furthermore, it can be ensured by means of the microswitch strip that neither a vehicle occupant nor an object is clamped between the blind and the second interior component. If a vehicle occupant or a body part of a vehicle occupant and / or an object is located between the blind and the second interior component, the microswitch strip is pressed onto the vehicle occupant or the object. As a result of this compression, the microswitch strip is actuated. As a result of the actuation of the microswitch strip, relative movement of the blind relative to the second interior component is prevented by means of the control device. When the microswitch strip is arranged on an electrically adjustable seat device and / or an electrically adjustable panorama screen device, it can be ensured that neither a vehicle occupant nor an object is clamped between the electrically adjustable seat device and the second interior component and / or between the electrically adjustable panorama screen device and the second interior component. For example, it can be ensured by means of the microswitch strip that a vehicle occupant or an object is prevented from being clamped between the seats of the electrically adjustable seat device and / or between the electrically adjustable seat device and a decorative element in the interior space of the motor vehicle. Furthermore, it is particularly advantageous in the case of the microswitch strip that the microswitch strip is configured particularly small and thus particularly space-saving.

[0007] It has proven to be particularly advantageous in this regard if the microswitch strip is arranged on the covering element when the microswitch strip is arranged on the covering roller, and if the microswitch strip is oriented relative to the covering element and / or the second interior component depending on the direction of movement of the covering element. This means that the microswitch strip is adapted in its orientation relative to the covering element and / or the second interior component to ensure that the microswitch strip is arranged between the interior components in the direction of movement of the interior components relative to one another. If the direction of relative movement of the covering element relative to the second interior component changes, the orientation of the microswitch strip relative to the covering element and / or the second interior component can accordingly be adapted to the change in the direction of relative movement. Thus, the anti-pinch protection is ensured by means of the microswitch strip in each case of relative movement, in particular when the relative movement between the covering roller and the second interior component changes.

[0008] It has proven to be particularly advantageous in this regard if the microswitch strip is arranged on a covering element of the covering roller which is configured as a latching element. The latching element can be latched to the second interior component, wherein the microswitch strip can be actuated when latching. In particular, the microswitch strip is actuated when the covering element is latched in the second interior component, whereby the further movement of the covering roller relative to the second interior component is prevented by means of the control device. It can thus be ensured that the further relative movement of the first interior component relative to the second interior component is prevented by means of the control device when the first interior component is latched in the second interior component. Here, for example, the microswitch strip can be arranged in front of the latching element in the direction of movement of the covering element relative to the second interior component, so that the microswitch strip comes into contact with the second interior component before the covering element when the covering element is moved relative to the second interior component. It can thus be ensured that the microswitch strip is reliably actuated when the latching element is latched in the second interior component.

[0009] In order to be able to arrange the microswitch strip particularly simply on the first interior component, it is provided according to the application that the microswitch strip is connected to the first interior component by means of a plug-in connection. To this end, the microswitch strip can have a foot which can be inserted into a recessed recess of the first interior component. A latching connection of the microswitch strip to the first interior component can thus be established. The plug-in connection enables the microswitch strip to be connected to the first interior component in a particularly simple and reliable manner, whereby the microswitch strip is particularly reliably held on the first interior component.

[0010] Further features of the application result from the figures and the figure description. The features and feature combinations mentioned in the description above and the features and feature combinations mentioned in the figure description below and / or shown alone in the figures can be used not only in the respective combinations specified, but also in other combinations or on their own.

[0017] An electrically lowerable cover roller blind 1 is shown in Figure 1 and 2 , which is arranged in a luggage compartment 2 of a motor vehicle, in particular of a motorized hatchback 3. The cover roller blind 1 is a first interior component of the motorized hatchback 3 which is movable within the luggage compartment 2. As shown in Figure 1 , the roller blind element 4 of the cover roller blind 1 can be moved out and in along the vehicle longitudinal direction x. As shown in Figure 2As shown in, the covering roller blind 1 can be moved as a whole in the vehicle vertical direction z of the motor caravan 3, so that the covering roller blind 1 can be arranged in the luggage compartment 2 or stowed in or below the floor trim 5 of the motor caravan 3. When the roller blind element 4 or the entire covering roller blind 1 is moved within the luggage compartment 2, a vehicle occupant and / or an object in the luggage compartment 2 can be pinched between the covering roller blind 1 and a second interior component of the motor vehicle, which can currently be the rear cover panel of the motor caravan 3 or can be the floor trim 5. In order to prevent a vehicle occupant or an object from being pinched, a microswitch strip 6 is arranged on the electrically movable covering roller blind 1. The microswitch strip 6 is a switch element which can be actuated by compression. The microswitch strip 6 is protrudingly arranged on the covering roller blind 1 in relation to the covering roller blind 1 in the respective movement direction of the covering roller blind 1. When the covering roller blind 1 is moved within the motor caravan 3, the microswitch strip 6 comes into contact with the vehicle occupant or the object in front of the covering roller blind 1. When contact with the vehicle occupant or the object is made, the microswitch strip 6 is triggered. As a result of the triggering of the microswitch strip 6, the covering roller blind 1 can be prevented from further movement. By means of the microswitch strip 6, it is thus possible to provide anti-pinch protection in the interior of the motor caravan 3.

[0018] In Figure 3a and 3b , the covering roller blind 1 is shown in section. The covering roller blind 1 comprises the roller blind element 4 and a covering element 7 which is configured as a latching element. The covering element 7 is held on the roller blind element 4. The microswitch strip 6 is arranged on the covering element 7. Both the microswitch strip 6 and the covering element 7 are protrudingly arranged in relation to the roller blind element 4 in the movement direction of the roller blind element 4. The microswitch strip 6 is in turn protrudingly arranged in relation to the covering element 7 in each movement direction of the roller blind element 4. In order to ensure this in a particularly advantageous manner, the covering element 7, which is currently rigidly connected with the microswitch strip 6, can be adjusted in its orientation in relation to the roller blind element 4. The covering element 7 is arranged on the end edge 8 of the roller blind element 4 and currently extends at least substantially over the entire length of the end edge 8 of the roller blind element 4. In order to orient the covering element 7 in relation to the roller blind element 4, the covering element 7 can be pivoted in relation to the roller blind element 4 about the end edge 8. Here, the covering element 7 is oriented in relation to the roller blind element 4 in accordance with the respective movement direction of the roller blind element 4, so that the microswitch strip 6 is arranged in front in the movement direction of the roller blind element 4 or the covering element 7. In Figure 3a , the orientation of the covering element 7 in relation to the roller blind element 4 is shown when the covering element 7 is moved in the vehicle longitudinal direction x of the motor caravan 3. The covering element 7 is oriented in relation to the roller blind element 4, in particular when the roller blind element 4 is unrolled, as shown in Figure 3a . When the covering roller blind 1 is moved in the vehicle vertical direction z and here in particular towards the floor trim 5 to stow the covering roller blind 1 in the floor trim 5, the orientation to Figure 3bthe orientation of the cover element 7 relative to the roller element 4.

[0019] In particular, the cover roller 1 can be unrolled and rolled up and can be moved in the interior of the motor vehicle 3 by means of the electronic control device 9, which is schematically represented in the figures by a block. By means of the electronic control device 9, a stop signal can be received from the microswitch strip 6, which characterizes the actuation of the microswitch strip 6. When the stop signal is received, the movement of the cover roller 1 or the unrolling or movement of the roller element 4 is prevented by means of the electronic control device 9. In this way, a particularly safe operation of the cover roller 1 can be achieved while providing anti-trapping protection.

[0020] In Figure 4 the arrangement of the microswitch strip 6 in the passenger compartment of the motor vehicle 3 is shown. Here, the microswitch strip 6 is arranged on a first vehicle seat 10 of a vehicle seat arrangement 11. The vehicle seat arrangement 11 currently comprises a further second vehicle seat 12. The first vehicle seat 10 is a first interior component of the motor vehicle 3, while the second vehicle seat 12 is a second interior component of the motor vehicle 3, wherein the first and second vehicle seats can be moved automatically relative to each other. In particular, the vehicle seats 10, 12 can be moved relative to each other by means of the electronic control device 9. Currently, the microswitch strip 6 is arranged on the side of the backrest of the first vehicle seat 10 which faces the second vehicle seat 12. Thus, when the microswitch strip 6 is collided with a vehicle occupant and / or an object between the vehicle seats 10, 12, the microswitch strip 6 is triggered. Due to the collision of the microswitch strip 6 with the vehicle occupant and / or the object being trapped between the microswitch strip 6 and the second vehicle seat 12, the microswitch strip 6 is actuated, and due to the actuation of the microswitch strip 6, the further movement of the vehicle seats 10, 12 relative to each other is prevented by means of the electronic control device 9.

[0021] In another embodiment, which is not shown in the figures, the microswitch strip 6 can extend in the vehicle transverse direction y and be arranged on the back side of a bench seat of the motor vehicle 3, wherein the microswitch strip 6 is triggered when a vehicle occupant and / or an object is trapped between the microswitch strip 6 and a rear cover panel of the motor vehicle 3 in the case of a movement of the bench seat in the vehicle longitudinal direction x rearward. Here, too, the movement of the bench seat can be prevented by means of the electronic control device 9 due to the actuation of the microswitch strip 6.

[0022] The microswitch strip 6 is in particular designed to recognize a force of approximately 6 to 10 Newton acting on the microswitch strip 6, and as a result of the recognition of the force, a signal is emitted to the electronic control device 9, which is actuated thereby. The respective actuation force which has to act on the microswitch strip 6 in order to actuate the microswitch strip 6 as well as the response angle of the microswitch strip 6 can be selected by means of the shape of the microswitch strip 6 and / or the material combination of the microswitch strip 6 elements.

[0023] exist Figure 5 Shown in the alternative Figure 3a and 3b The covering element 7 shown in FIG. 1 is designed as a covering element 7 . Figure 5 The covering element 7 shown in FIG. 1 is suitable in particular for a roller blind. Figure 5 The covering element 7 shown in FIG comprises a flip member 13 and a telescopic shielding portion 14, each of which is made of plastic. Figure 3a and 3b In the embodiment of the covering element 7 shown in FIG, and in Figure 5 In the embodiment of the cover element 7 shown, the cover element 7 has corresponding undercut recesses 15 into which the microswitch strip 6 is inserted. The microswitch strip 6 now has feet 16 that can snap into the recesses 15, thereby securing the microswitch strip 6 on the cover element 7 in a particularly simple and reliable manner. The microswitch strip 6 can thus be inserted into the recess 15 via a plug-in connection and fixed therein via the undercuts.

[0024] Figure 3a and 3b The cover element 7 shown in FIG has a latching area 17, via which the cover element 7 can be latched in a second interior component of the motor vehicle 3, in particular in a decorative element of the motor vehicle 3. The microswitch strip 6 makes latching of the cover element 7 in the second interior component optional, since when the microswitch strip 6 is actuated by the electronic control unit 9, a relative movement of the cover element 7 relative to the second interior component is prevented, so that an external clamping function is not required.

[0025] The electrically lowerable roller blind 1 is fixedly located in the luggage compartment 2 of the motor vehicle 3 and can be automatically lowered into a separate storage compartment, behind the floor trim 5, as desired by the customer. Furthermore, the roller blind element 4 of the roller blind 1, when extended in the vehicle longitudinal direction x, can be automatically moved in and out depending on the orientation of the tailgate of the motor vehicle 3. When the microswitch strip 6 is actuated, particularly due to a blockage or jam, the contacts within the microswitch strip 6 close. As a result of the closed contacts, the electronic control unit 9 detects the current flowing in the microswitch strip 6 and reverses the movement of the roller blind element 4. Thus, when the microswitch strip 6 is actuated, further movement of the first interior component relative to the second interior component in the direction of movement is prevented and the first interior component is then moved in the opposite direction relative to the second interior component.

[0026] In particular, the invention shows how a microswitch strip 6 can be used for electrical interior functions.
