Description

The present invention relates to a bearing device for connecting a damper to a body of a vehicle according to the preamble of independent claim 1 and to a method for producing a bearing device for connecting a damper to a body of a vehicle.

Shock absorbers for vehicles are known from the prior art. In this case, such shock absorbers usually act together with a spring to decouple the vehicle with respect to vibrations and forces from the chassis. In particular, the shock absorber contributes to influencing a vibration behavior of the vehicle and thereby increase the comfort of a driver. The shock absorber is connected to the body. Depending on the damper and / or chassis vibrations can be transmitted in the form of sound from the damper to the body at certain loads, so that this is perceived as rumbling in the interior of the vehicle.

In order to decouple the damper acoustically from the body, it is also known to provide damper bearings, which have an acoustic damping effect. Depositors based on natural rubber are often provided to effect the acoustic decoupling. However, a disadvantage of such systems is that natural rubber usually has a dynamic hardening which increases with the frequency of the transmitted vibrations. As a result, the acoustic decoupling capability drops correspondingly with increasing hardening of the material.

Bearing devices for dampers are eg in the FR 1 597 182 A , of the DE 10 2011 089 259 A1 , of the DE 10 2007 026 471 A1 , of the DE 101 47 604 A1 , as well as the EP 2 618 020 B1 shown. Further, polyurethane elastomers are, for example, from DE 10 2006 030 391 A1 known. In addition, the reveal DE 10 2012 202 418 A1 , the DE 10 2010 041 406 A1 , as well as the DE 10 2007 048 183 A1 magnetorheological elastomers.

It is therefore an object of the present invention, at least partially overcome the above known from the prior art disadvantages. In particular, it is an object of the present invention to reduce the manufacturing cost of a bearing device for a damper and / or to improve damping characteristics of a bearing device for a damper for acoustic decoupling.

The above object is achieved by a bearing device having the features of claim 1 and a method for producing a bearing device having the features of claim 8.
Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that have been described in connection with the storage device according to the invention apply, of course, also in connection with the method according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or can be.

According to the invention, the bearing device for connecting a damper to a body of a vehicle on a fastener, which is attachable to the body.
Furthermore, the bearing device has a first housing element, which is at least partially decoupled from the fastening element by a damping means. In this case, the damping means comprises a casting elastomer.

By the bearing device can thus be at least partially prevented by the at least partial decoupling of the first housing member from the fastener that sound is transmitted at a critical frequency from the damper to the body. The first housing element is preferably connected to the damper or connectable to the damper. The fastening element is preferably directly or indirectly connectable or connected to the body. To connect the bearing device to the body, the fastener attachment interfaces, preferably holes, which are arranged for example symmetrically to a median plane of the bearing device on the fastener, so that a fastener, such as a screw or a rivet can be passed to the bearing device or connect the damper to the body, ie to bolt for example to the body. In order to realize the at least partial decoupling of the first housing element from the fastening element may preferably be provided that the damping means is at least partially or completely disposed between the fastening element and the first housing element. This results in a kind of floating mounting of the two components relative to each other and accordingly a decoupling of vibrations and thus of sound. The damping means may in particular have only one damping element or a plurality of damping elements. Preferably, the damping means is rotationally symmetrical to over different directions to realize homogeneous damping properties. In particular, the damping means may comprise a plurality of damping elements, which are arranged jointly or structurally separated. Preferably, the casting elastomer may be an elastomer which is pourable in the preparation of the damping agent. Preferably, the cast elastomer may be in an assembled state of the bearing device in an at least partially or fully cured state. In particular, the cast elastomer may comprise a silicone, a cold cast elastomer, a thermoplastic polyurethane and / or a particularly incompressible cast elastomer comprising diphenylmethane diisocyanate (MDI). As a result, a compression of the damping means in particular directly cause a change in shape of the damping means, so that the damping properties can be controlled, for example via geometric shapes. In particular, such cast elastomers are furthermore particularly suitable for damping acoustic vibrations. Thus cast elastomers have in particular a favorable for acoustic decoupling, dynamic course of a damping property. In this case, the casting elastomer may be pre-cast and arranged correspondingly manually with the first housing element and the fastening element when the bearing device is to be mounted. Due to the viscosity of casting elastomers, in particular of thermoplastic polyurethane, shaping in particular can also take place without molding during casting. In addition, for example, the cast elastomer may have improved microbial resistance, so that the life of the bearing device may be prolonged.

This results in a reliable decoupling with respect to sound, which can be produced in a simple manner. In addition, individually tailored to the conditions of use form of the damping means can be produced inexpensively by the casting elastomer. Thus, for example, different thicknesses of the damping means may be poured in order to adapt the bearing device to the conditions of use or to the type of model without it being necessary, for example, to create a new, individual mold for foaming a corresponding insert part. In addition, a vulcanization, as is often provided for example in natural rubber omitted.

It is also conceivable in a bearing device according to the invention that the damping means is at least partially encapsulated with the fastening element, so that the damping means is connected to the fastening element cohesively. Thus, a first damping element of the damping means may preferably be cast onto the fastening element in order to be able to effect an acoustic decoupling in the mounting state of the bearing device. By a direct encapsulation of the damping means with the fastener, the fastener may be configured as a customizable component, which is adjusted according to the model type accordingly. Thus, both attachment interfaces for connecting the damper to a body in the context of the configuration of the fastener can be adjusted, as well as the damping means. Furthermore, mechanical processing steps for attaching the damping means, such as e.g. a flanging at least one of the housing elements, omitted. As already described above, the damping means may for example be adapted in shape and / or propagation to provide corresponding damping properties. An integral connection can advantageously be achieved by hardening the casting elastomer of the damping means on the fastening element so that the damping means adheres to the fastening element. Preferably, the fastening element may be designed to be flat, wherein the damping means or the casting elastomer of the damping means is applied to at least one side, preferably on two sides of the fastening element. Additionally or alternatively, it may be provided that the cast elastomer is cast with the first housing element, so that the damping means is connected to the first housing element cohesively. Thus, the casting elastomer, for example, during the assembly of the bearing device first be poured onto the fastening element, and the first housing element before the curing of the casting elastomer with the damping means are brought into contact, so that a material connection with both the fastener, and with the first Housing element results and thus a secure fit of the damping means is ensured. However, if the damping means is applied to the fastening element independently of the first housing element, there is the advantage that a production of the fastening element with the damping means can be provided temporally and spatially independently of the first housing element. Furthermore, this may result from the fact that during operation of the bearing device, the damping means is movable independently of the first housing element, for example, to be able to slide along in expansion in a certain direction due to compression of the damping means on the first housing element. As a result, the dynamic properties of the storage device can be improved overall. To cast the damping means, the damping means may in particular comprise a thermoplastic polyurethane, by means of which a shaping in a simple manner can be realized.

In the context of the invention may further be provided that the fastening element is at least partially decoupled by the damping means of a second housing member, wherein the fastening element is arranged with the damping means between the first and the second housing member. By providing a second housing element, which acts in particular as a lid, it can be ensured, for example, that the fastening element and the damping means are arranged secured in at least two directions, so that a secure fastening of the entire bearing device results. Preferably, the damping means may comprise at least a first damping means, which is arranged between the fastening element and the first housing element and a second damping element, which is arranged between the second housing element and the fastening element. This can result in both directions a reliable decoupling between the fastener and housing or damper. In particular, the first housing element and the second housing element may be formed symmetrically at least partially to a median plane of the fastener, so that the decoupling properties of the damping means in both directions are at least substantially equal. In addition, by providing the second housing element, for example, the mounting position of the damping means and the fastening element can be defined in particular during assembly, so that, for example, a compression of the damping means can be specified during assembly. Preferably, the first and the second housing element are at least in one direction movable relative to each other.

Advantageously, in a bearing device according to the invention, the first housing member having a guide portion, which causes a counter-guide portion of the second housing member, an axial alignment of the first and second housing member to each other. The axial alignment may preferably comprise an alignment on a guide axis of the guide section and / or the counter guide section. By the guide portion or the counter guide portion can thus be ensured that move during operation of the bearing device, the first housing member and the second housing member only linearly along an axis and thus a defined decoupling is ensured. As a result, in particular the damping properties of the damping means can be reproducible, since the degrees of freedom of the bearing device are limited. In addition, it is ensured by the guide portion or the counter guide portion that the first housing element is mounted to the second housing element in the correct manner and thus quality assurance is ensured.

It is also conceivable that in a bearing device according to the invention a biasing means is provided, through which the damping means is compressible. Preferably, the first housing element and the fastening element and / or the second housing element can be braced against each other. Thus, in particular along the guide section or the counter guide section, the biasing means may be guided, so that in the axial direction, a bias voltage can be introduced into the bearing device in order to impart a predefined compression to the damping means during assembly. By the biasing means, the damping properties can be influenced according to a compression of the damping means. The compression then preferably take place in one direction, wherein the damping means changes its shape and at least partially evades in another direction. In particular, the damping properties of the damping means can thus be adjusted individually during assembly and / or adjusted. The biasing means may comprise a nut which cooperates with a thread of the damper. Thus, a threaded rod of the damper can be inserted through, for example, the first and the second housing element and accordingly serve the damper as a counter-stop means for the first housing element, while the nut acts on the second housing element and thus both housing elements are braced against each other. If the damping means is arranged with the fastening element between the two housing elements, this is mitverspannt according to the aforementioned constellation and thus compresses the damping means.

In a bearing device according to the invention, advantageously, the first and / or the second housing element may have a starting contour, by means of which at least one damping property of the damping means can be influenced during a deformation of the damping means. Preferably, the starting contour may have a curve shape and / or a paragraph. Additionally or alternatively, the fastener may have a start-up contour. For this purpose, for example, a lowered trained mounting portion may be provided, on which the damping means is arranged, wherein the starting contour, for example, as a paragraph, may extend at the edge of the attachment portion. If the damping means is compressed due to a bias voltage and / or in operation due to particular acoustic oscillations, this deforms by moving in a direction different from the compression direction dodging. Due to the starting contour, it can be provided that the damping means runs against the starting contour during the deformation and thus the starting contour provides the damping means with a further resistance which can influence the damping properties. As a result, for example, a movement or expansion of the damping means in the direction of the start-up contour can be prevented and thus result in a reduced damping and thus a harder damping curve. While a progressive shape of the damping characteristic can be produced, for example, by a curve shape of the starting contour, an abrupt change, in particular a sudden increase, of the damping characteristic can be achieved by means of a shoulder. The damping property may preferably be a stiffness of the damping means, which in turn may affect the decoupling of the bearing device. In this case, a reduced decoupling can have a positive effect on the vibration characteristics of the bearing device in which z. B. thereby natural frequencies are shifted and thus critical natural frequencies in the operation of the vehicle in favor of uncritical natural frequencies of the vibrations, ie frequencies that rarely or not occur, for example, during operation of the vehicle, avoided or reduced. In particular, can be improved by the start-up contour further elastokinematics of the bearing device. Thus, it is conceivable in particular in an oblique installation of the damper in the vehicle that transverse or shearing forces occur, which are at least partially receivable by contact of the damping means with the start-up contour.

In the context of the invention may further be provided that a bonding agent is provided for connection of the damping means to the fastening element and / or to the first and / or second housing element. Preferably, the bonding agent can be applied to the fastener before the damping means is applied or is potted with the fastener so that a bonding between the damping means and fastener, in particular by thermal activation, is supported by the bonding agent. An adhesion promoter may be understood to mean a preferably liquid substance which supports the physical and / or chemical bonding between the damping means and the fastening element or the first and / or second housing element. Preferably, the fastening element and / or the first and / or the second housing element may comprise a metal, preferably aluminum, so that the strength of the bearing device is increased. The bonding agent can thus ensure a secure connection even with two differently shaped joining partners.

It is also conceivable that in a bearing device according to the invention at least one damping property of the damping means can be influenced by a magnetic field. Thus, it is conceivable that the damping means magnetizable particles, in particular metal particles, which are magnetizable by the magnetic field. If the magnetic field is now generated during operation of the bearing device, the particles can affect the damping property of the damping means, so that the decoupling behavior of the damping means changes. In particular, the damping characteristic may be a stiffness of the damping means. The magnetic field may preferably be produced by electromagnetic coils. The electromagnetic coils may preferably be arranged inside the first housing element and / or the second housing element, in particular injected, in order to generate the magnetic field. Preferably, magnetization may cause an increase in stiffness of the damping means. In addition, the electromagnetic coils may be connected to a voltage source of the vehicle or be connectable to be controlled accordingly. As a result, the driving dynamics of the vehicle can be influenced in a targeted manner. In particular, the electromagnetic coils with an active sensor such. B. an accelerometer of the vehicle, be connectable to adapt the damping property adaptive. As a result, the bearing device may, for example, also be connectable to an adaptive damper and adapted with an adaptive adaptation of a main damping characteristic of the damper itself also with respect to an acoustic damping characteristic. Additionally or alternatively, a piezoelectric actuator element can be provided by which a damping property of the damping means can be influenced.

Vorzugsweise kann es sich bei der Lagervorrichtung um eine erfindungsgemäße Lagervorrichtung handeln. Damit bringt ein erfindungsgemäßes Verfahren die gleichen Vorteile mit sich, wie sie bereits ausführlich in Bezug auf eine Lagervorrichtung beschrieben worden sind. Insbesondere ergibt sich durch das erfindungsgemäße Verfahren eine einfache, kostengünstige Fertigungsmöglichkeit. So kann das Gießen des Gießelastomers bzw. des Dämpfungsmittels z.B. automatisiert durchführbar sein, so dass eine Reproduzierbarkeit einer hohen Qualität gesteigert sein kann und gleichzeitig Kosten eingespart werden können. Vorzugsweise kann das Gießelastomer dabei bei Raumtemperatur oder bei niedriger Erwärmung gießbar sein. So ist es denkbar, dass beim Gießen mehrere Komponenten des Gießelastomers zusammengegossen werden. Insbesondere kann das Gießelastomer ein Polyester und ein Polyether aufweisen, welche beim Gießen vereinigt werden. Vorzugsweise kann im Rahmen des Verfahrens ein Schritt eines Aushärtens des Gießelastomers vorgesehen sein. Das Aushärten kann dabei eine Beschleunigung einer chemischen Reaktion, beispielsweise durch Rühren, umfassen. Nach dem Gießen kann vorzugsweise eine bestimmte Aushärtezeit vorgesehen sein, bevor das Befestigungselement mit dem ersten Gehäuseelement und dem Dämpfungsmittel angeordnet wird oder nach dem das Anordnen durchgeführt worden ist.

Das Befestigungselement und das Gehäuseelement können vorzugsweise einzeln gefertigt werden und beispielsweise als Frästeil, Drehteil oder dergleichen ausgebildet sein. According to a further aspect of the invention, a method for producing a bearing device for the connection of a damper to a body of a vehicle is claimed. The method comprises the following steps:

• Providing a fastening element which can be connected to the body and a first housing element,
• Casting a casting elastomer so that a damping agent is at least partially formed by the casting elastomer,
• - Arranging the fastening element and the first housing element, so that the fastening element is at least partially decoupled from the first housing element by the damping means.

Preferably, the storage device may be a storage device according to the invention. Thus, a method according to the invention brings the same advantages as have already been described in detail with respect to a bearing device. In particular, the method according to the invention results in a simple, cost-effective production possibility. For example, the casting of the casting elastomer or of the damping agent can be carried out automatically, so that a reproducibility of a high quality can be increased and costs can be saved at the same time. Preferably, the cast elastomer may be castable at room temperature or at low heat. So it is conceivable that during casting several components of the casting elastomer are poured together. In particular, the cast elastomer may comprise a polyester and a polyether, which are combined during casting. Preferably, in the context of the method, a step of curing the casting elastomer can be provided. The curing may include an acceleration of a chemical reaction, for example by stirring. After casting, a certain curing time may preferably be provided before the fastener is placed with the first housing member and the cushioning means or after the placement has been performed. By the method, the casting elastomer can be cast individually in any shape, so that an adjustment and / or adjustment of the damping properties of the damping means is preferably feasible close to the assembly. The fastening element and the housing element can preferably be manufactured individually and be designed, for example, as a milled part, rotary part or the like.

In particular, the fastening element and / or the first housing element may be made of metal and / or plastic.

In the context of the invention, it is also conceivable that the casting elastomer is poured during casting directly on the fastening element and / or the first housing element, so that a cohesive connection is formed. Thereby, the fastening element can be pre-assembled with the damping means, wherein preferably a first damping element is poured onto a first side of the fastening element and a second damping element on a second side of the fastening element. In order to improve a material bond, it can be provided that a bonding agent is applied to the fastener before the casting of the casting elastomer is performed. By casting on the fastening element and / or the first housing element can thus be ensured a particularly simple manufacture of the bearing device, since a preforming of the damping means is not necessary and at the same time a possibility of attachment of the damping means is provided in the bearing device. In addition, the possibility of adjustment in particular continues to shift to the mounting of the bearing device so that manufacturing tolerances can be compensated and / or pre-planning measures can be reduced. In particular, a provision of a molding tool of the damping means is not necessary by the direct casting on the fastening element, so that further investment costs can be saved here.

The method steps in a method according to the invention can preferably be carried out individually in the order described or in a different order. In particular, individual and / or all steps can be executed in parallel and / or repeated.

In the following figures, the identical reference numerals are used for the same technical features of different embodiments.

1 shows a storage device according to the invention 10 in a sectional partial view in a schematic representation in a first embodiment. In this case, the storage device 10 a first housing element 11 and a second housing member 12 on, between which a fastener 13 is arranged, on which a casting elastomer comprehensive damping means 14 is poured, leaving a flat design of the bearing device 10 can be achieved. Preferably, the damping means 14 further formed rotationally symmetrical, so that a homogeneous damping property of the damping means 14 at least in one plane. The damping agent 14 has a first damping element 15 and a second damping element 16 on, which in each case on one side of the fastening element 13 are arranged. The fastener 13 is at least two sides opposite to the first and the second housing element 11 . 12 forth, allowing attachment interfaces 13.1 exposed. About the attachment interfaces 13.1 is the fastener 13 by screwing to a body 3 of a vehicle 1 connectable. The first and second housing element 11 . 12 are about a biasing agent 22 screwed against each other, wherein the biasing means 22 a nut that has a thread of the damper 2 acts. For this purpose, the first housing element 11 a damper interface 24 on, through which the bearing device 10 on the damper 2 can be arranged.

To the thread through the first and second housing element 11 . 12 to guide, have the guide section 20 and the counterpart section 21 a passage opening 25 on. In order to ensure an axial securing, the first housing element 11 a guide section 20 on, that with a counterpart section 21 of the second housing element 12 an axial alignment of the first and second housing element 11 . 12 causes each other. As a result, at least two degrees of freedom, namely a movement parallel to the main plane of the fastener 13 at least partially blocked, so that a relative displacement of the first housing element 11 to the second housing element 12 only in the axial direction is possible. As a result, a secure fit of the storage device 10 or the individual parts of the storage device 10 given. By the bias of the biasing means 22 and / or by vibrations in the operation of the storage device 10 becomes the cushioning agent 14 at least partially compressed or laterally expanded. Due to the fact that the first damping element 15 opposite a first second damping element 16 acts, a balance is created, which ensures that the fastener 13 in particular centrally between the damping elements 15 . 16 is arranged. When compressed by the biasing means 22 when both damping elements 15 . 16 are similarly shaped, both damping elements 15 . 16 essentially symmetrically loaded. In operation, in turn, depending on the direction of the vibration amplitude of one of the damping elements 15 . 16 loaded while the other of the damping elements 15 . 16 relaxes. The damping agent 14 can thus by a deformation of the damping elements 15 . 16 Absorb vibration energy or convert it into heat. As a result, the first and second housing element 11 . 12 from the fastener 13 at least partially in particular acoustically decoupled, so that vibrations, in particular sound, from the damper 2 to the fastener and the fastener 13 to the body 3 be transferred reduced. The casting elastomer of the damping agent 14 may preferably comprise a thermoplastic polyurethane. This results in a simple and cost-effective production of the storage device 10 , wherein at the same time an individualization of the storage device 10 to the respective field of application is easy to carry out. When casting the damping agent 14 with the fastener 13 is preferably an adhesion promoter 17 provided so that a material connection between the fastener 13 and the damping means 14 is favored with different materials. In addition to the amount of cast elastomer can have a damping property 41 of the damping agent 14 also be controlled by other parameters. Additionally or alternatively to the default via the biasing means 22 it is further provided that the first and second housing element 11 . 12 a start-up contour 23 exhibit. In the illustrated embodiment, the start-up contour comprises 23 a waveform 23.1 in the inner region of the housing elements 11 . 12 which is formed substantially symmetrically. Will the damping agent 14 in the form of damping elements 15 . 16 compressed, the material deviates especially laterally, so that in the inner region of the bearing device 10 the damping agent 14 to the housing elements 11 . 12 invests. This experiences the damping means 14 in the area of the start-up contour 23 a resistor, which due to the waveform 23.1 also increases progressively with increasing compression. In addition, the fastener has 13 a receiving section 13.2 on, in which the damping means 14 with the fastener 13 is shed. Furthermore, a start-up contour 13.3 of the fastening element 13 provided as a paragraph between the mounting interfaces 13.1 and the receiving section 13.2 is trained. Analogous to the start-up contour 23 the housing elements 11 . 12 can the damping agent 14 also to the start-up contour 13.3 of the fastening element 13 invest. Due to the sudden geometric change, this can cause a sudden increase or a sudden reduction of the damping property 41 respectively.

2 shows a storage device 10 for connecting a damper 2 to a body 3 of a vehicle 1 in a sectional partial view in another embodiment in an exploded view. Here is the storage device 10 formed substantially like the bearing device of the first embodiment. In contrast to the first embodiment, the embodiment of the 2 Furthermore, a start-up contour 23 on, which on the one hand a waveform 23.1 and on the other hand a paragraph 23.2 , By the paragraph 23.2 can be a damping property 41 of the damping agent 14 be further influenced because, for example, in certain load conditions, the second damping element 16 against the paragraph 23.2 runs when the damping element 16 in the direction of the paragraph 23.2 spreads. This will the damping property 41 of the second damping element 16 increased abruptly. Preferably, it may be in the damping property 41 to act in particular a dynamic stiffness. Thus, a tarnishing of the damping means 14 against the start-up contour 23 cause an increase in rigidity in the operation of the storage device. Moreover, it becomes clear from the second embodiment that the bearing device 10 , as in the first embodiment, is pre-assembled, and for example by a biasing means 22 , as in 1 is displayed, is set. To further improve the dynamic properties may also be provided an additional spring, which, for example, on the first housing element 11 can be arranged.

3 schematically shows possible, exemplary courses of a damping property 41 opposite a deformation path 40 , In particular, the damping property 41 a stiffness of a damping means 14 , Preferably according to the first or second embodiment. On the one hand, this is a first course 41.1 represented, which a harder course of the damping property 41 shows. So the damping property increases 41 of the damping agent 14 initially almost linear before an abrupt increase begins. This can be done for example by a hard start, z. B. against a paragraph 23.2 a start-up contour 23 being shaped. Furthermore, a second, softer start 41.2 which, for example, due to a softer start contour in the form of a waveform 23.1 is caused.

The 4a to 4d show damping means 14 , which with a fastener 13 are shed, in different embodiments. So shows 1 a damping agent 14 , which is a first damping element 15 and a second damping element 16 having, wherein the damping elements 15 . 16 have a rounded surface. As a result, for example, increases the resistance, which the damping means 14 a compression initially only slightly before the resistance through a wider portion of the damping elements 15 . 16 increases more. 4b further shows a damping means 14 with a first and a second damping element 15 . 16 whose cross-sections are formed substantially rectangular, so that the resistance in the compression of the damping means 14 increases substantially linearly. 4c further shows a damping means 14 in a further embodiment, wherein the damping means 14 a first damping element 15 having, which with two sides of a receiving portion 13.2 of the fastening element 13 is shed. For this purpose, the fastener 13 an opening through which the damping means 14 passed through. Furthermore, the first damping element 15 of the damping agent 14 a first side of the housing 15.1 for engagement with a first housing element 11 and a second housing side 15.2 for engagement with a second housing element 12 on. Preferably, the first housing side 15.1 different from the second side of the housing 15.2 be formed to the damping properties of the damping means 14 to influence. For example, the first side of the housing 15.1 as shown straight, while the second housing side 15.2 has a waveform. Again, this affects the compression of the damping means 14 out. In addition, shows 4d a damping agent 14 which comprises a first and a second damping element 15 . 16 having, wherein the respective cross-section of the damping elements 15 . 16 in a direction toward the interior of the storage device 10 is formed parabolic, so that, for example, results in shear forces a change in the damping properties. In addition or as an alternative to the illustrated shapes, further embodiments of the damping means, such as a substantially pyramidal shape, a formation of further damping elements or the like, are conceivable.

5 further shows a storage device according to the invention 10 in a further embodiment in a sectional schematic view.
