Description

[0001] The present invention relates generally to motion control devices and, more particularly, to damper devices for reducing and, in particular, harmonizing a movement of a second component movable relative to a first component.

[0002] In recent years, dampers or damping devices have been developed to slow and / or control the relative movement of components. For example, vehicles are often equipped with various pivot assemblies (e.g., tailgates, cargo doors, glove compartments, center console lids, hoods, etc.). The components of pivot assemblies are connected to rotate relative to each other, and one or more dampers are connected to the components to regulate or harmonize their rotation speed.

[0003] In the same way, linear dampers are also known to reduce, slow down or harmonize a linear movement between two components.

[0004] Certain known damper devices are designed to dampen or slow down the relative movement of components that pivot due to gravity. If a lower component, such as a glove compartment lid, is released to pivot relative to a higher component, such as a dashboard, the damper device slows the downward rotation of the lower component.

[0005] Such damper devices known from the prior art are often designed as air dampers or hydraulic dampers, in which a working fluid (air, hydraulic fluid, or grease) is forced through an orifice or throttle from a first working chamber into a second working chamber, thereby damping, i.e., reducing, a force / movement introduced into the damper device. Rotary dampers are also known whose operation is based on the shear principle.

[0006] In the automotive sector, rotary dampers that contain a linear damper are often used to slow down, dampen or harmonize the movements of parts such as glove compartment lids or movable flaps.

[0007] Such linear dampers with a rotary damper contained therein are disclosed, for example, in the document EP 0 846 886 B1, in the document EP 1 344 958 B1 or in the document DE 10 2006 000 940 B4.

[0008] Particularly in the automotive industry, there is a need to illuminate interior spaces that are either closed or open to the component to be damped.

[0009] For example, WO 2007 / 080448 A1 discloses a damper device with an integrated switch. The switch integrated in the damper device can be electrically connected to a light source located remotely from the damper device, for example, in a glove compartment panel. For this purpose, a cable is routed through the panel from the damper device, which has the switch, to the light source. A movement of the component, for example, the glove compartment lid, activates the switch, thus turning on the light source, for example, when the glove compartment lid is opened.

[0010] A disadvantage of the damper devices with integrated switches known from the prior art is that the installation of the damper devices and the connection as well as the functional testing of the switch integrated in the damper device are relatively complex. In particular, to check whether the switch integrated in the damper device is functionally connected to a corresponding electrical circuit, the individual electrical contacts between the connection pins of the switch integrated in the damper device and the vehicle wiring must currently be manually checked. Since the damper device is usually installed in difficult-to-access areas, particularly in the vehicle interior, this functional test is not only time-consuming but also prone to errors.

[0011] Based on the problem described, the object of the present invention is to provide a damper device for damping, i.e. braking, or for harmonizing a rotational or linear movement of a component, preferably a component mounted so as to be movable in the space of a vehicle, wherein a switching device is integrated in the damper device, and wherein the damper device can be installed easily and thus inexpensively, while at the same time a robust power supply for an electrical or electronic component, such as a light source, can be provided. In particular, during installation of the damper device, a check as to whether the switch integrated in the damper device is functionally connected to a corresponding electrical circuit should be simplified.

[0012] This object is achieved according to the invention by the subject matter of independent patent claim 1, wherein advantageous developments of the damper device according to the invention are specified in the dependent patent claims.

[0013] Accordingly, the present invention relates in particular to a damper device for reducing and in particular harmonizing a movement of a second component movable relative to a first component, wherein the damper device has a first damper component, which is in particular firmly connected or connectable to the first component, and a damping mechanism.

[0014] The damping mechanism can optionally further comprise a housing which is in particular firmly connected or connectable to the second component and in which a second damper component is accommodated or can be accommodated at least partially or in some areas.

[0015] The first damper component is movable relative to the housing of the damping mechanism—at least over a predefined or definable distance. Upon movement of the first damper component relative to the housing of the damping mechanism, the first damper component interacts with the second damper component, which is at least partially or regionally accommodated in the housing of the damping mechanism, in such a way that the movement of the first damper component relative to the second damper component and / or the optionally provided housing of the damping mechanism is decelerated or harmonized.

[0016] In the damper device according to the invention, it is provided that a switching mechanism with a first switching contact and a second switching contact is arranged or integrated on the second damper component, for example in the optionally provided housing of the damping mechanism. In particular, it is provided that at least one actuating region is designed on the first damper component such that, upon movement of the first damper component relative to the second damper component and / or relative to the optionally provided housing of the damping mechanism, an electrically conductive connection between the first switching contact and the second switching contact is established or broken with the aid of the at least one actuating region.

[0017] The damper device according to the invention is characterized in particular in that the first switching contact and the second switching contact are each electrically connected to an extended contact element, wherein the contact elements of the first and second switching contacts are led out of a switch housing of the switching mechanism and preferably out of its switch base on the assembly side as electrical terminals. The damper device comprises a diagnostic system for monitoring an electrical connection, in particular a plug connection, of the electrical terminals.

[0018] In preferred implementations of the damper device according to the invention, the diagnostic system has an electrical diagnostic resistor, wherein the contact elements of the first and second switching contacts are or can be connected to the electrical diagnostic resistor of the diagnostic system, in particular as required.

[0019] In this context, it is particularly conceivable that, in order to diagnose the electrical connection, in particular the plug connection, of the electrical terminals, a diagnostic current flowing through the diagnostic resistor is evaluated. For this purpose, a device for detecting an electrical current flowing through the diagnostic resistor is used, which can be part of the diagnostic system.

[0020] Preferably, the switching mechanism of the damper device consists of only two components, namely the first switching contact and the second switching contact, so that the switching mechanism can be integrated into the switch housing of the damper mechanism in a particularly easy-to-implement manner without significantly increasing the overall dimensions of the damper device. By using only two components for the switching mechanism, the manufacturing costs of the damper device according to the invention are also low.

[0021] The switching mechanism can be actuated in a simple yet effective manner using the at least one actuating region of the first damper component. For this purpose, it can be provided, for example, that the at least one actuating region of the first damper component establishes or breaks an electrically conductive connection between the first switching contact and the second switching contact upon movement of the first damper component relative to the second damper component and / or relative to the optionally provided housing of the damping mechanism.

[0022] With this design, no additional components are required to operate the switching mechanism. This also has a positive effect on manufacturing costs and the overall construction or packaging dimensions of the damper device.

[0023] By providing a diagnostic system, preferably with an electrical diagnostic resistor, which is connected or connectable between the contact elements of the first and second switching contact of the switching mechanism, the switching mechanism of the damper device as a whole is capable of being diagnosed.

[0024] During or after installation of the damper device with the integrated switching mechanism, the functionality of the switching mechanism, and in particular the electrical cable connection between the terminals of the switching mechanism and an electrical circuit, can be diagnosed in a simple and effective manner by evaluating a measuring current flowing through the electrical diagnostic resistor. Particularly in technical systems, particularly vehicle interior components that are often subject to mechanical stress, this provides a reliable way to test for a defect in the switching mechanism or wiring with as little effort and as little difficulty as possible. The resistor interposed between the contact elements of the first and second switching contacts of the switching mechanism makes the entire system diagnostically capable and can also be continuously monitored.

[0025] The electrical terminals leading out of the switch housing, and in particular from the switch base of the switch housing of the switching mechanism on the assembly side, can be electrically and mechanically connected to wiring elements, for example, by soldering, welding, clamping, or crimping, forming a diagnosable functional unit that can be individually diagnosed by a control unit, for example, by detecting voltage drops at the terminals. The control unit can thus detect whether the switching mechanism is connected, whether it is open or closed, or whether a short circuit is present.

[0026] Thus, according to implementations of the damper device according to the invention, it is provided that the contact elements of the first and second switching contact, which are led out of the switch housing of the switching mechanism as electrical terminals, each have a connection pin via which the switching contacts of the switching mechanism are or can be electrically connected to an electrical circuit, wherein the electrical diagnostic resistor is arranged between the connection pins inside or outside the switch housing.

[0027] To check whether the connection pins of the switching mechanism are functionally connected to the electrical circuit, an electrical current flowing through the diagnostic resistor can be detected.

[0028] Various resistor types can be used as electrical diagnostic resistors. A discrete component, such as a thin-film resistor, a thick-film resistor, or a foil resistor, is preferably used as a diagnostic resistor.

[0029] Alternatively, a wire-wound resistor, particularly a precision wire-wound resistor, can be used as an electrical diagnostic resistor. A wire-wound resistor consists of an insulated wire of a specific diameter wound around a body. The resistance value and initial characteristics are determined by the wire diameter, wire length, and material alloy used.

[0030] An electrically conductive layer applied as a paste or an electrically conductive material applied in particles can also be used as an electrical diagnostic resistor. By adding conductive additives in particle or fiber form, such as carbon, graphite, conductive carbon black, carbon fibers, or other conductive metallic particles or fibers, such as copper, aluminum, or stainless steel fibers, the electrical conductivity, i.e., the specific resistance, of the conductive layer or material, and thus the specific resistance of the diagnostic resistor, can be adjusted.

[0031] An electrically self-conducting polymer can also be used as an electrically conductive layer or as an electrically conductive material.

[0032] According to embodiments of the damper device according to the invention, the diagnostic system and in particular the electrical diagnostic resistor of the diagnostic system can be detachably electrically connected to the contact elements of the first and second switching contacts.

[0033] In particular in this context, in implementations of the damper device according to the invention, it is provided that the diagnostic system of the damper device is connected or connectable, preferably in the form of an adapter, to a housing of the damper device and in particular to a housing of the switching mechanism.

[0034] The diagnostic resistor of the diagnostic system can also be integrated into a connector with at least two pins.

[0035] Preferably, the switching mechanism of the damper device according to the invention is designed to interrupt or allow a current flow through an electrical consumer depending on a position of the first damper component relative to the second damper component.

[0036] In principle, it is conceivable that the first switching contact and / or the second switching contact are / is designed as a spring contact and in particular as a spring contact pin.

[0037] A spring contact or spring contact pin is a contacting element that is spring-loaded. Such a spring contact can consist of a guide tube (also called a pin sleeve or housing), a spring, and a plunger. The three components are preferably crimped together in such a way that they cannot come apart, yet the plunger can still freely move a certain amount of spring travel in the longitudinal direction. When installing such a switch contact designed as a spring contact, the compression spring is preferably preloaded, which means that the spring contact pin already has a certain initial force—commonly referred to as preload—in its zero position.

[0038] Alternatively, it is also conceivable for the first switching contact and the second switching contact to each be designed as a contact tongue. The contact tongue can have a contact area, preferably at an end region of the corresponding contact tongue.

[0039] The two switching contacts of the switching mechanism, designed as contact tongues, are preferably designed to be spring-loaded in such a way that they form a galvanic connection across the two contact areas.

[0040] In particular, it is conceivable that the first switching contact has a spring contact at a first end region and a plug contact, in particular in the form of a plug contact pin, at a second end region opposite the first end region, wherein the first switching contact is received or can be received via a plug connection in a plug housing of the switching mechanism, which is preferably designed to be at least partially or regionally complementary to the plug contact.

[0041] Alternatively or additionally, it is possible for the second switching contact to have a spring contact at a first end region and a plug contact, in particular in the form of a plug contact pin or connection pin, at a second end region opposite the first end region, wherein the second switching contact is received or can be received via a plug connection in a plug housing of the switching mechanism, which is preferably designed to be at least partially or regionally complementary to the plug contact.

[0042] In this context, it is particularly preferred that the plug housing of the switching mechanism is connected to the second damper component in a detachable or replaceable manner.

[0043] It would be advantageous if the first switching contact and the second switching contact of the switching mechanism were of identical construction in order to make the construction of the damper device or the switching mechanism integrated in the housing of the damping mechanism particularly simple.

[0044] According to implementations of the damper device according to the invention, it is provided that the at least one actuating region of the first damper component is designed to move into or out of a contacting region between the first switching contact and the second switching contact upon movement of the first damper component relative to the second damper component and / or relative to the optionally provided housing of the damping mechanism and thus to separate or establish an electrically conductive connection between the first switching contact and the second switching contact.

[0045] This is a particularly easy-to-implement yet effective solution for activating or deactivating the switching mechanism as needed, particularly depending on the relative position of the first damper component. Of course, other embodiments are also possible.

[0046] In a conceivable realization, in particular of the aforementioned embodiment variant of the damper device according to the invention, it is provided that the at least one actuating region of the first damper component is formed from a material that is at least superficially electrically non-conductive and / or is designed in a fin-like manner, and wherein the at least one actuating region of the first damper component is designed in particular as a separating element that can be inserted and removed between the first switching contact and the second switching contact, preferably via a relative movement between the first damper component and the second damper component.

[0047] It is particularly preferably provided that the second damper component of the damper device according to the invention has a lamellar or rib structure with a plurality of projecting regions, in particular in the form of lamellar, ribs or knobs, which are elastically deflectable at least partially or in regions in the direction of movement of the first damper component relative to the second damper component or relative to the housing of the damping mechanism.

[0048] In particular, it is advisable for the first damper component to have a comb structure with at least one and preferably a plurality of teeth or projections, wherein at least in a state in which the first damper component is not moved relative to the second damper component and / or relative to the optionally provided housing of the damping mechanism, the at least one tooth or projection of the comb structure is arranged at least partially or regionally in a meshing manner between two mutually adjacent projecting regions of the lamella or rib structure.

[0049] This embodiment offers decisive advantages over the damper devices discussed in the introduction to the description and generally known from the prior art. Because the functioning of the damping mechanism in this embodiment of the damper device according to the invention is not based on the displacement of a working fluid, in particular a hydraulic fluid (oil), or on a gas, in particular air, the damping mechanism and thus the entire damper device can be implemented much more simply from a structural perspective, while at the same time, the damping characteristics of the damper device can be adjusted in a particularly effective manner, particularly individually, i.e., in a user-specific manner.

[0050] In addition, the damping characteristics of the damper device are largely independent of ambient conditions, especially temperature.

[0051] In a further development of the last-mentioned embodiment of the damper device according to the invention, it is provided that the at least one tooth or projection of the comb structure is arranged and / or designed between two adjacent projecting regions of the lamellar or rib structure in such a way that when the first damper component moves relative to the second damper component and / or relative to the optionally provided housing of the damping mechanism (and thus relative to the second damper component), at least a portion of the projecting regions of the lamellar or rib structure is elastically deformed with the aid of the at least one tooth or projection of the comb structure, with simultaneous conversion of kinetic energy into elastic deformation work.

[0052] In other words, the damping mechanism used in the damper device according to the invention is based on a mode of operation in which at least part of the introduced kinetic energy is converted into thermal energy through elastic deformation. Preferably, the projecting regions of the lamella or rib structure are formed from an elastic material, in particular a plastic material, whose elasticity varies only slightly—if at all—over the widest possible temperature range.

[0053] Alternatively or additionally, it is preferred that the at least one tooth or projection of the comb structure is formed from a material, in particular plastic material, which is harder than the material of the projecting regions of the lamella or rib structure.

[0054] According to one aspect, the last-mentioned embodiment of the damper device according to the invention is characterized in particular in that the projecting regions of the lamella or rib structure have a geometry which tapers, in particular conically tapered, at least partially or in regions in the direction of the comb structure, as seen in the cross section of the projecting regions.

[0055] Alternatively or additionally, according to the further aspect of the invention, it can be provided that the at least one tooth or projection of the comb structure has a geometry that tapers, in particular conically tapered, at least partially or regionally in the direction of the lamella or rib structure, as seen in the cross section of the at least one tooth or projection.

[0056] These measures ensure that the protruding areas of the lamella or rib structure contact at least one tooth or projection of the comb structure on one side, thus achieving harmonious power transmission. This reduces any noise generated during operation of the damper device. At the same time, harmonious power transmission ensures particularly low-wear operation of the damper device.

[0057] In particular, in this context, according to embodiment variants of the damper device according to the invention, it is provided that the at least one tooth or projection of the comb structure has a shape which is at least partially at least substantially complementary to the shape of the projecting regions of the lamella or rib structure.

[0058] This is a simple yet effective measure for ensuring the most harmonious force transmission possible between the comb structure and the lamella or rib structure. Such harmonious force transmission implies a homogeneous force distribution and a flat force amplitude, which can prevent or at least reduce any noise generated when the damping mechanism or damping device is activated.

[0059] In principle, it is conceivable for the lamella or rib structure to comprise a lamella or rib support and the aforementioned protruding regions connected to the lamella or rib support. In this case, it is advisable for the lamella or rib support to be made of a material that is harder than the material of the protruding regions, in particular a plastic material. The lamella or rib structure is preferably formed using a two-component plastic injection molding process.

[0060] This further reduces the manufacturing effort of the damper device according to the invention.

[0061] According to a particularly preferred implementation of the damper device according to the invention, it is designed as a linear damper, in which the first damper component is designed to move linearly or at least substantially linearly relative to the second damper component.

[0062] Preferably, the second damper component has two opposing lamellae or rib supports, which are designed to form a preferably form-fitting, and more preferably at least partially or regionally form-fitting, sliding guide for a rod-shaped support part of the first damper component, allowing translation. Each lamellae or rib support of the second damper component has a lamellae or rib structure with a plurality of projecting regions, in particular in the form of lamellae, ribs, or knobs.

[0063] On the other hand, the rod-shaped support part of the first damper component preferably has a comb structure with a plurality of teeth or projections which are arranged on mutually opposite side surfaces of the rod-shaped support part in such a way that, when the rod-shaped support part moves through the sliding guide, the teeth or projections pass through the projecting regions of the lamella or rib structure of the second damper component, in particular in a combing manner, with simultaneous elastic deflection of the latter.

[0064] According to a further development of the last-mentioned embodiment of the damper device according to the invention, it is provided that a distance between the two opposing lamella or rib supports of the second damper component is variably adjustable in order to thus adjust a damping factor of the damper device.

[0065] In this context, it is particularly conceivable for the two opposing lamella or rib supports of the second damper component to be preloaded by means of a spring element or spring elements. Similarly, a freewheel function of the damper device designed as a linear damper is feasible.

[0066] Alternatively or additionally, it is conceivable that at least one of the two mutually opposite lamella or rib supports of the second damper component is mounted displaceably relative to the rod-shaped support part via a guide running obliquely to the direction of movement of the rod-shaped support part, in particular in such a way that when the rod-shaped support part moves in a first direction through the sliding guide, the at least one lamella or rib support of the second damper component is in a first position, and that when the rod-shaped support part moves in a second direction opposite to the first direction through the sliding guide, the at least one lamella or rib support of the second damper component is moved into a second position and / or is in a second position.In the second position of the at least one lamella or rib carrier of the second damper component, a distance between the two opposing lamella or rib carriers of the second damper component is greater than in the first position of the at least one lamella or rib carrier of the second damper component.

[0067] The distance between the two opposing lamella or rib supports of the second damper component in the second position can in particular be selected such that freewheeling of the rod-shaped support part is possible through the sliding guide.

[0068] In the embodiment of the damper device according to the invention, in which the damper device is designed as a linear damper, the at least one actuating region of the first damper component can be formed as a region protruding from the rod-shaped support part perpendicular to the longitudinal direction (and thus perpendicular to the direction of movement) of the rod-shaped support part. Preferably, the at least one actuating region of the first damper component is formed at an end region of the rod-shaped support part in order to activate or deactivate the switching mechanism when the first component is in its fully extended or fully retracted state relative to the second component.

[0069] Of course, it is also conceivable that several actuation areas are arranged at different positions of the first damper component or the rod-shaped support part in order to activate or deactivate the switching mechanism as required depending on the movement pattern of the first damper component.

[0070] According to an alternative implementation of the damper device according to the invention, it is designed as a rotary damper in which the first damper component is rotatably mounted relative to the second damper component.

[0071] In this case, it is advisable for the first damper component to be designed as a sleeve-shaped part in which the second damper component designed as a pin-shaped part is accommodated at least partially or in regions, in particular coaxially and / or cocentrically, with a sleeve-shaped plate carrier of the damping mechanism, wherein the at least one actuating region of the first damper component is designed as a region protruding from the sleeve-shaped part in the longitudinal direction of the sleeve-shaped part, and wherein the at least one actuating region of the first damper component is preferably formed on an end region of the sleeve-shaped part.

[0072] According to implementations of the damper device according to the invention, the damping mechanism has a housing with a first housing region in which the second damper component is at least partially or partially accommodated, and through which the first damper component is or can be guided at least partially or partially.

[0073] The housing of the damping mechanism further comprises an additional (second) housing section in which the switching mechanism with the first switching contact and the second switching contact is accommodated. In addition, the second housing section can optionally also accommodate a corresponding electrical circuit or electronics associated with the first and second switching contacts.

[0074] Preferably, a window region is formed between the first housing region and the second housing region, through which the at least one actuating region of the first damper component can be introduced into a region between the first switching contact and the second switching contact. The window region further preferably serves as a guide for guiding the at least one actuating region of the first damper component when the first damper component is moved relative to the housing of the damping mechanism.

[0075] Preferably, the second housing area has a closure element which is preferably connected to the main body of the second housing area via a film hinge in order to close the second housing area, in particular in a dust-tight manner, if required.

[0076] However, the invention is not limited to damper devices in which at least one damper component has a lamella or rib structure with a plurality of projecting regions, in particular in the form of lamellae, ribs or knobs.

[0077] Rather, the invention also relates to damper devices which are designed in particular as gas spring dampers and have a switching mechanism with a first and second switching contact.

[0078] Thus, according to embodiments, it is provided that the damper device is designed as a gas spring damper, in which the second damper component has a body that is at least partially or partially cylindrical, in which a piston element of the first damper component is guided in a longitudinal direction of the cylindrical body relative to the cylindrical body so as to be linearly movable.

[0079] In this embodiment of the damper device according to the invention, it is particularly provided that the cylindrical body has a first end region facing the switching mechanism and an opposite second end region, wherein the switching mechanism has a corresponding housing structure for at least partially or partially accommodating the first and second switching contacts. The housing structure is preferably detachably connected to the first end region of the cylindrical body via an end region facing the first end region of the cylindrical body.

[0080] In this case, it is advisable for an end region of the housing structure facing the first end region of the cylindrical body to have a sleeve-like or flange-like connection region which is designed to form an at least partially or partially positive connection with the first end region of the cylindrical body and in particular to receive the first end region of the cylindrical body at least partially or partially.

[0081] In implementations of the damper device according to the invention designed as a gas spring damper, it is provided that a closure element, in particular a cap-shaped closure element, is arranged on the second end region of the cylindrical body, which closure element has a guide and sealing unit through which a piston rod arranged concentrically to the central longitudinal axis of the cylindrical body and connected to the piston element is guided out of the cylindrical body.

[0082] When implementing the last-mentioned embodiment of the damper device according to the invention, it is provided that, in a state connected to the first end region of the cylindrical body, the housing structure and the in particular cap-shaped closure element define an interior space of the cylindrical body, wherein the interior space of the cylindrical body is divided by the piston element into a first housing sub-space facing the switching mechanism and into an opposite second housing sub-space.

[0083] Preferably, the piston element has at least one valve or throttle body, in particular in the form of at least one valve disc, via which a gas exchange between the first and second housing sub-chamber is possible in a particularly throttled manner when the piston element moves relative to the cylindrical body.

[0084] In embodiments of the damper device according to the invention, it is provided that the at least one throttle or valve body is designed in such a way that a speed-dependent harmonization of the piston element takes place, in particular in such a way that the damping by the piston element is greater the faster the piston element is displaced in the cylindrical body relative to the cylindrical body.

[0085] It is also possible that the damper device is designed as a silicone or oil damper.

[0086] For example, it is conceivable for the damper device to be designed as a rotary damper, which has a rotor that is rotatably mounted inside the rotary damper. A brake fluid, such as silicone oil, between the rotor and an outer wall of the rotary damper provides braking damping when the rotor rotates within the rotary damper. A pinion can be mounted on a rotor shaft, which meshes with a toothed segment, for example, part of a rack.

[0087] Such a rotary damper can be mounted in a stationary housing part. Furthermore, a linear guide for the rack can be provided, which is pivotally mounted about the axis of the rotor shaft and keeps the rack engaged with the pinion, regardless of the rack's rotational position.

[0088] The guide allows the rack to move translationally within the guide, causing a corresponding rotation of the pinion. Any pivoting of the rack is absorbed by the rotating guide. Therefore, any movement of the component to be damped results in a linear movement in the guide and corresponding damping via the rotary damper.

[0089] The invention further relates to the use of the aforementioned damper device as a movement control device for reducing and in particular harmonizing a movement of a second component movable relative to a first component.

[0090] Furthermore, the invention relates to a vehicle component, in particular an interior vehicle component, which has two components that can be moved relative to one another, wherein a relative movement of these components is dampened or reduced by means of a damper device of the aforementioned type according to the invention.

[0091] The invention is described in more detail below using an exemplary embodiment with reference to the accompanying drawings.

[0092] They show: Fig. 1 schematically and in a side view an exemplary embodiment of the damper device according to the invention in the form of a linear damper with a switching mechanism in the open state; Fig. 2 schematically and in a side view the exemplary embodiment of the damper device according to the invention according to Fig. 1 with the switching mechanism in the closed position; Fig. 3 schematically and in a side view of the in Fig. 1 or in Fig. 2 shows the switching mechanism used in the exemplary embodiment of the damper device according to the invention in the closed state; Fig. 4 schematically and in a plan view the switching mechanism according to Fig. 3; and Fig. 5a, b each show an equivalent circuit diagram of the switching mechanism according to Fig. 3, in an open state ( Fig. 5a) and in a closed state ( Fig. 5b) of the switching mechanism.

[0093] The exemplary embodiment of the damper device 1 according to the invention according to Fig. 1 or Fig. 2 has as the first damper component a rack 2 which has an opening at one end region for connection to a component to be damped (not shown).

[0094] In Fig. 1 shows only the back of the rack 2, not the front with the teeth. Instead, the back shows an elongated, flat surface.

[0095] Furthermore, a damping mechanism 3 designed as a rotary damper is indicated, which is located in a housing. The damping mechanism 3 is of conventional design and contains a rotor whose rotational movement is damped by a mechanism. For example, it is conceivable that the rotor rotates in a viscous fluid. Alternatively, the rotor is rotatably mounted relative to elastic ribs of a rib structure, so that the use of a fluid can be dispensed with.

[0096] A shaft of the rotor is connected to a pinion that meshes with the rack 2 (also not shown). This slows or dampens the movement of the rack 2.

[0097] Of course, the invention is not limited to a specific damping mechanism.

[0098] In Fig. 1 shows only a guide 4 of the rotary damper, in which the rack 2 is guided linearly. As can be seen, the guide 4 essentially comprises two circularly curved segments, which are arranged at a distance from one another and from a damper housing 5 serving as the second damper component, forming a guide gap for the rack 2. On opposite sides of the segments, tongues are formed, which rest against the flat surface to achieve a sliding guide 4.

[0099] The rack 2 has an actuating section at one end on opposite sides.

[0100] A switch housing 6 is attached to the damper housing 5. The switch housing 6 has a T-shaped groove in cross-section, which interacts with a T-shaped spring of the damper housing 5. As can be seen, another T-shaped spring is formed on the opposite side of the damper housing 5. The switch housing 6 can therefore be attached to either side of the damper housing 5. The attachment is such that a locking mechanism occurs between the spring and the groove, although this is not shown in detail.

[0101] The switch housing 6 contains two fixed contact elements 8, of which only one contact element 8 is visible. The fixed contact elements 8 serve as the first and second switching contacts of the switching mechanism 7 and are arranged parallel to each other.

[0102] The fixed contact elements 8 can generally have an S-shape. They are formed from a suitable metal. A first leg extends through a corresponding slot in the switch housing 6, which is molded in one piece from plastic material. A tongue-shaped bend ensures that the leg cannot be pulled out.

[0103] Another leg rests against a wall of a cavity in the switch housing 6, and a third leg extends into the cavity, in which a movable contact element 11 is also mounted. For this purpose, the approximately U-shaped movable contact element 11 is inserted with a first leg into a recess in the switch housing 6, with a bend ensuring that the leg cannot be easily pulled out. A second leg can be bent toward or away from the leg.

[0104] If the rack 2 is in a Fig. In the position shown in Figure 2, the leg of the movable contact element 11 rests against the legs of the fixed contact elements 8 due to the inherent spring tension. These are, as mentioned, parallel and spaced apart from one another. This establishes an electrical connection between the fixed contact elements 8.

[0105] Meanwhile, if the rack 2 moves into a Fig. 1, the leg of the movable contact element 11 is lifted from the associated actuating section and is therefore no longer in contact with the sections of the fixed contact elements 8. The switch mechanism 7 is thus opened.

[0106] Fig. 3 shows schematically and in a side view the Fig. 1 or in Fig. 2 shown exemplary embodiment of the damper device 1 according to the invention, the switching mechanism 7 in the closed state, while Fig. 4 schematically and in plan view the switching mechanism according to Fig. 3.

[0107] On the other hand, in Fig. 5 an equivalent circuit diagram of the switching mechanism 7 according to Fig. 3, in an open state ( Fig. 5a) and in a closed state ( Fig. 5b) of the switching mechanism 7.

[0108] It can be seen that the switching mechanism 7 has a first switching contact 8 and a second switching contact 8, wherein upon movement of the first damper component or the rack 2 relative to the second damper component or the damper housing 5, an electrically conductive connection between the first switching contact 8 and the second switching contact 8 is established or broken.

[0109] The first and second switching contacts 8 are each electrically connected to an extended contact element 9, wherein the contact elements 9 are led out of the switch housing 6 of the switching mechanism 7 and preferably out of its switch base on the assembly side as electrical terminals. In particular, it is provided that the contact elements 9 of the first and second switching contacts 8 are connected to an electrical diagnostic resistor 12.

[0110] In detail, the contact members 9 of the first and second switching contact 8, which are led out as electrical terminals from the switch housing 6 of the switching mechanism 7 and preferably from its switch base, each have a connection pin 10 via which the switching contacts 8 of the switching mechanism 7 are or can be electrically connected to an electrical circuit, wherein the electrical diagnostic resistor 12 is arranged between the connection pins 10 inside or outside the switch housing 6.

[0111] In this context, it is conceivable that a device for detecting an electrical current flowing through the diagnostic resistor 12 is connected or connectable to the connection pins 10 in order to check whether the connection pins 10 of the switching mechanism 7 are functionally electrically connected to the electrical circuit.

[0112] The electrical diagnostic resistor can in particular be designed as a discrete resistor.
