Description

The invention relates to a supporting element for an elongate, mechanical actuating element in a motor vehicle according to the preamble of claim 1, an actuating element arrangement in a motor vehicle having at least one such supporting element according to the preamble of claim 14 and a motor vehicle component according to the preamble of claim 15.

Support elements for elongate mechanical actuators of an actuator assembly in a motor vehicle are known from the prior art. In particular in motor vehicle doors, a number of actuating functions are provided by means of elongate actuating elements, in particular so-called Bowden cables.

If the actuator in question is designed as a Bowden cable, it consists in principle of two parts, namely a tubular sheath made of a flexible material (Bowden cable) and an operating strand guided therein (Bowden cable soul). At both ends of the shell of the actuating strand is in front and has at its ends fittings. As a rule, a connecting piece is fastened to an actuating member and the connecting piece arranged at the other end is fastened to an organ to be actuated. Such actuators may be, for example, door handles or shift levers, while the respective associated, to be actuated members, a motor vehicle lock and / or a transmission can be.

Especially in motor vehicle doors, for example in a manual closing operation, actuators are often exposed to vibration and shock. If the actuators are installed close to body components or other walls, they will strike regularly. This leads to unwanted noise and can also cause wear of the actuating element, in particular of the actuating jacket, result. To avoid this, it is known to surround the actuating jacket with a foam jacket with good damping properties.

The known support element ( DE 20 2016 104 153 U1 ), from which the invention proceeds, is designed to be elongated overall and is pushed onto a Bowden cable. It has longitudinally extending, resilient support sections, via which the Bowden cable can be supported on a wall of a motor vehicle component. Due to the elongated shape on the one hand and the resilience of the support sections on the other hand, a good definition of the support element on the actuating element on the one hand and good damping properties on the other.

In addition to the laying of the actuators often the laying of electrical cables is required. For this purpose, the damping arrangement of the support element, which provides the damping properties, at least one cable receptacle for positive retention of a cable. In this way, the cable can be kept parallel to the actuating element with one and the same support element.

Often it is necessary to lay a corresponding actuator and electrical cables in relatively small spaces. A unit of support element, actuator and electrical cables must then be bent at least partially under certain circumstances. However, this is only possible to a limited extent with a support element as described above.

The invention is based on the problem, the known support member to design and further develop such that an arrangement of an elongated, mechanical actuator with a support element in a small space is possible in a simple manner.

This object is achieved with a support element according to the preamble of claim 1 by the features of the characterizing part of claim 1.

The elongated, mechanical actuator is depending on the structure of a corresponding actuator assembly either a Bowden cable comprising a Bowden cable and a movably guided Bowden cable or just a part of a Bowden cable, in particular the Bowden cable, which will be explained in more detail below.

First of all, the proposal assumes that the damping arrangement allows support against a wall of a motor vehicle component, wherein the support is damped by means of the damping arrangement. This means that any noise that goes back to the support, in particular to a stop or the like, on a wall of a motor vehicle component, be avoided or reduced by the damping arrangement. In that regard, the term "attenuation" is to be understood in the present case.

For the provision of the above damping function, the damping arrangement is made yielding in a preferred direction transverse to the longitudinal axis of the recorded actuating element.

Furthermore, according to the proposal, the support element has a plurality of damping tubes extending transversely to the longitudinal axis, forming the damping arrangement, which enable the support to bear against the wall of the motor vehicle component and, to that extent, form support sections. The damping ears extend from a body of the support member to an outer end, the outer end of each damping tube forming a support bearing, in particular a two-dimensional support bearing (planar support) or a one-dimensional support bearing (point support or linear support). These are preferably located on a common circumferential circumferential in the circumferential direction about the longitudinal axis of the support cylindrical contour, so in the mounted state, all the same distance from the longitudinal axis or the elongated mechanical actuator.

The damping tubes are proposed to be shaped so that their cross-section widens in the direction of the outer end relative to a section transverse to the longitudinal axis of the support element and then reduces towards the outer end. "Towards the outer end" means that the reduction of the cross-section extends all the way to the outer end. Towards the outer end, the damping tubes are thus tapered. In this case, in the direction of the outer end of the respective damping tube, the reduction of the cross section follows in particular directly on the widening of the cross section. The location of the largest cross-section then defines a bottleneck between two damping tubes.

The proposed provision of damping tubes on a common body instead of a generally elongated support member has the advantage that an actuator with corresponding support elements is much more flexible. In this way, an elongated, mechanical actuating element provided with corresponding supporting elements can also readily be arranged in small construction spaces. Also, a support element with damping ears can be provided with relatively small dimensions in the direction of the longitudinal axis, which facilitates the mounting on the actuating element in comparison to a generally elongated support element. Further advantages of the comparatively small dimensions in the direction of the longitudinal axis compared to a generally elongated support element are on the one hand that the noise is reduced due to relative movements between the support element and the actuator, and on the other hand, that the material of the respective support element absorbs less water in absolute terms , In addition, the particular shape of the damping ears and the bottleneck created thereby allows a simple fixation of an electrical cable between two mutually adjacent in the circumferential direction damping tubes.

With claim 2, it is proposed that the damping tubes together with the base body provide a substantially omega-shaped (omega-shaped) outer contour. About such an outer contour, the said constriction between circumferentially adjacent damping ears can be particularly easily realized. "Substantially Ω-shaped" means that the damper ear has a wider outer portion and a narrower portion toward the parent body. In the narrower section, the respective damping tube, in particular also in the transition to the base body, may have a curved, in particular uniformly curved, course or an angular course. The narrower section forms in particular a constriction according to claim 3.

Claim 4 defines various cross-sectional profiles, based on a section transverse to the longitudinal axis of the support element, the damping tubes. It is essential in all of these cross-sectional curves that the damping tubes extend outwardly to a certain point and then taper again to form said local bottleneck between two adjacent damping tubes, the cross-section preferably first expanding continuously and then tapering continuously, in particular until the end outer end of the respective damping tube out.

In the embodiment according to claim 5, the damping ears have an at least sections, preferably at least predominantly, more preferably completely, curved course. As I said, but also corners and / or straight sections can be formed.

The damping ears are each formed integrally with the base body according to the preferred embodiment according to claim 6. The material of the support element is in particular a foam, plastic or rubber material.

According to the further preferred embodiment according to claim 7, the damping ears in the direction of the longitudinal axis of the support element have a smaller extension than the main body. Additionally or alternatively, the damping ears have a smaller extension in the direction of the longitudinal axis of the support element than transversely to the longitudinal axis. Alternatively, the damping ears may also have a smaller extension in the direction of the longitudinal axis of the support element than in the circumferential direction about the longitudinal axis. The latter is preferably true at least for the extent in the circumferential direction in the portion of the damping tube, in which this extent is the greatest, so the cross section, based on a section transverse to the longitudinal axis of the support element, is greatest.

The damping tubes preferably have a relatively small thickness (extension parallel to the longitudinal axis), with their thickness being in particular less than 5 mm, preferably less than 2 mm, particularly preferably less than 1 mm. Particularly preferably, the damping tubes are disc-shaped (claim 8), ie have substantially parallel sides, which are parallel to the longitudinal axis of the support element and which have a correspondingly small distance from each other.

According to the preferred embodiment according to claim 9, a plurality of damping tubes are arranged around the longitudinal axis of the support element, that is to say in the aforementioned circumferential direction, in particular at uniform angular intervals. This plurality of damping tubes is in particular identical in shape. The damping tubes are preferably arranged so that they are aligned with one another in the circumferential direction. Also, the attenuation ears in cross section in each case to a plane through which the longitudinal axis extends, be formed mirror-symmetrically (claim 10).

According to the further preferred embodiment according to claim 11 is formed between two circumferentially adjacent damping tubes at least one cable receptacle for positive retention, in particular exactly one cable receptacle for positive retention of a cable, which may be in particular an electrical cable. The cable receptacle is preferably arranged in the region of the lower end of the two adjacent damping tubes. Outwardly, the cable receptacle is limited by said local bottleneck.

According to the further preferred embodiment according to claim 12, a slot extends parallel to the longitudinal axis through the support element, wherein the slot allows unfolding of the support member for assembly purposes and thus easier attachment to the actuating element. In the mounted and / or unmounted state, a gap is formed in particular through the slot, so that the material surfaces are thus spaced from one another in this region for the purpose of simplifying the assembly. The material surfaces formed by the slot may also be hooked or hooked into each other to prevent unwanted loosening after assembly of the support member on the actuator.

In the likewise preferred embodiment according to claim 13, the damping tubes have recesses or are perforated, whereby the damping properties are improved.

The above-mentioned problem is further solved according to another teaching in an actuator assembly according to the preamble of claim 14 by the features of the characterizing part of claim 14. After further teaching, the same advantages, as described above in connection with the support element. The support element of the actuating element arrangement is preferably designed as described above.

The above-mentioned problem is further solved according to yet another teaching by a motor vehicle component according to claim 15 with such an actuator assembly. The proposed motor vehicle component can be, for example, a motor vehicle door or a module of a motor vehicle door that is equipped or can be equipped with components such as a motor vehicle lock and / or a window guide and / or a window lift drive. In this case, the actuating element arrangement forms in particular a mechanical connection between a door handle and a motor vehicle lock (claim 16).

It should be emphasized that the proposed support element in addition to the damping tubes also has the main body. It is conceivable to arrange the unit of main body and damping tubes on a Bowden cable by the entire unit of body and damping tubes is arranged on the Bowden cable or to the Bowden cable. The Bowden cable case represents a compression-resistant shell of the Bowden cable, in which the axially movable Bowden cable core runs. The unit of main body and damping ears is attached in this case, in particular to the Bowden cable, but can also be molded or molded to this, for example in single or multi-component injection molding, in particular in 1K or 2K process. In principle, it is also conceivable to mold or inject the damping ears directly to the bowden cable sheath, likewise, for example, in single-component or multi-component injection molding processes, in particular in 1K or 2K processes. In the latter case, then the elongated mechanical actuator is not the entire Bowden cable, but the Bowden cable, since the Bowden cable is part of the support element.

In 1 is a proposed actuator assembly 1 in a motor vehicle with a proposed support 2 shown. Furthermore, the actuator element arrangement 1 an elongate, mechanical actuator 3 on. The actuator 3 is a geometric longitudinal axis L assigned along the center line of the actuator 3 extends. The geometric longitudinal axis L follows the course of the actuator 3 and here and preferably also the longitudinal extension of the support element 2 , so that the term "longitudinal axis" is interpreted accordingly wide. In the following, with "longitudinal axis" always the common longitudinal axis L the recorded actuator 3 and also the support element 2 meant, here and preferably coaxial with the actuator 3 runs.

The actuator 3 is here and preferably bendable and has a tubular jacket 3a and an actuation strand 3b on. The confirmation thread 3b is preferably a stranded wire. In that regard, the actuator 3 here and preferably a Bowden cable with one of the tubular jacket 3a formed Bowden cable and one of the actuating strand 3b formed Bowdenzugseele.

At the ends of the actuator 3 can fittings 3c be attached for attachment to an actuator or an organ to be operated. Furthermore, the tubular sheath 3a also a connection piece 3d for connecting a motor vehicle component, in particular to a motor vehicle lock and / or a support structure for a door handle.

Preferably, the actuator assembly 1 or the support element 2 Component of a motor vehicle lock arrangement. Then, the actuator, for example, a door handle and the organ to be actuated, an actuating lever, in particular for opening the motor vehicle lock, be.

The structural design of the proposed support 2 show in various embodiments in particular the 1 to 3 , 4 shows an actuator assembly with several in the direction of the longitudinal axis L spaced-apart support elements 2 ,

The support element 2 has a basic body 2a on, which extends along the longitudinal axis L and an actuator receptacle 4 for receiving the actuating element 3 formed. In the embodiments according to the 1 to 4 is the main body 2a from the tubular jacket 3a of the actuating element 3 different. In an alternative embodiment (not shown here), the main body of the support element but also of the tubular jacket which surrounds an actuating arm, may be formed, in which case the mechanical actuator is the actuating arm and the jacket is part of the support element.

The support element 2 according to the 1 to 4 several transverse to the longitudinal axis L extending, a damping arrangement 5 forming damping ears 2 B on. The support element 2 is preferably a total of elastically deformable, but dimensionally stable. This means that after elastic deformation, it essentially resumes its original shape from before deformation.

Here and preferably, the support member extends 2 along the actuator 3 , which is coaxial with the actuating element 3 is arranged. The recorded actuator 3 is like 1 shows, via the damping arrangement 5 can be supported transversely to the longitudinal axis L.

The bracing is through the damping tubes 2 B accomplished, each with its inner end to the main body 2a are connected and extending from their inner end transverse to the longitudinal axis L extend to its outer end. The outer end then forms each a support bearing 2c , In all illustrated and insofar preferred embodiments, the support element 2 with a plurality of support bearings 2c equipped, that, made of muffling ears 2 B to the longitudinal axis L are arranged in a circumferential direction U. This results in the possibility of supporting the actuating element 3 largely independent of the pivotal position of the support element 2 relative to the longitudinal axis L ,

In the proposed support 2 It is essential that the cross section of the damping tubes 2 B , relative to a section transverse to the longitudinal axis L , so a cut along in 1 represented level e , so in the direction of the extended to the outer end and then reduced to the outer end again, that is a local bottleneck 6 between each two in the circumferential direction U adjacent damping ears 2 B is formed.

The term "local bottleneck" means that in the circumferential direction U the edges of the damping tubes 2 B locally approach at a location where the distance between the damping ears 2 B is minimal. Before and behind this bottleneck 6 the cross-section decreases again, in particular continuously. "Local" in this context means that, based on a section transverse to the longitudinal axis L the support element 2 or along the plane e , the two outer contours of circumferentially U mutually adjacent damping tubes 2 B only at one point P . P ' have the shortest distance from each other and the distance between the outer contours on both sides of the point P . P ' enlarged again.

Through the described, local bottleneck 6 is between two in the circumferential direction U adjacent damping ears 2 B a cable receptacle 7 for the positive retention of a particular electrical cable 8th educated. The cable receptacle 7 is from the bottleneck 6 seen from grundköperseitig arranged and in particular to the body 2a limited by this. This is the respective cable holder 7 in the region of the lower end of the two mutually adjacent damping tubes 2 B arranged.

Through the described cable holder 7 results in a double use of the support element 2 , This serves both to support the actuating element 3 as well as for receiving the cable 8th in the cable receptacle 7 ,

In motor vehicles are both the actuator 3 as well as the cable 8th constantly exposed to mechanical vibrations and impulses. By an abutment of actuator 3 and / or cables 8th on structural parts of other vehicle components, such as a wall W of a motor vehicle door, unwanted noise often arises. In addition, the cable can 8th and / or the actuating element 3 be exposed to wear by a constant impact and / or slipping on automotive components, which may affect the long-term functionality. The proposed support 2 avoids with its damping order 5 and the special shape of the muffling ears 2 B these unwanted effects reliably. At the same time the whole of the support element 2 , Actuator 3 and cables 8th also flexible enough to accommodate even in small spaces. The cable 8th can also be due to the special shape of the damping tubes 2 B especially easy in the cable holder 7 insert as the cable 8th only at the local bottleneck 6 , in particular under elastic deformation of the two adjacent damping tubes 2 B , must be passed.

2 shows different variants of damping tubes 2 B , which differ in the representation shown by their outer contour. The variants of a support element 2 initially have in common that, based on a section transverse to the longitudinal axis L the support element 2 or in the direction of the plane e , the muffling ears 2 B together with the main body 2a provide an outer contour with a substantially Ω-shaped course. Due to the Ω-shaped course, the respective support element 2 a narrow body-side portion and a wide outer (head-shaped) portion. In all variants shown in 2 has the cross section of the damping tubes 2 B a constriction 9 on, here and preferably adjacent to the inner end of the respective damping tube 2 B or adjacent to the main body 2a is arranged. The constriction 9 each represents the area with the smallest cross section of the damping tube 2 B represents.

As compared to the 2a) to d ) is recognizable, the variants of the damping ears differ 2 B here and preferably in the area of their constriction 9 , In detail is in 2a) provided that the cross section of the damping tubes 2 B starting from the main body 2a initially reduced towards its outer end, namely in the region of the constriction 9 , then immediately extended, namely to the bottleneck 6 , and finally to the outer end, immediately behind the bottleneck 6 , again reduced.

In the variant according to FIG. 2b), the cross-section of the damping tubes is shown 2 B starting from the main body 2a initially constant in the direction of its outer end, namely in the region of the constriction 9 , then widens immediately to reach the bottleneck 6 and then decreases again from here to the outer end of the respective damping tube 2 B ,

In the variant according to 2c ) It is such that the cross section of the damping tubes 2 B starting from the main body 2a extended directly in the direction of its outer end, in such a way that the outer contour initially follows a straight line and then a curved course until reaching the bottleneck 6 assumes, with the cross section after the bottleneck 6 immediately reduced to the end.

In the variant according to 2d ) widens the cross section of the damping tubes 2 B also directly from the main body 2a in Direction of the outer end, wherein the outer contours in the entire region of the Querschnitterweiterung has a curved course, even here until reaching the bottleneck 6 after which the cross-section then immediately decreases again to the outer end.

The outer contour of the damping tubes 2 B Thus, at least in sections, preferably at least predominantly, particularly preferably completely, may have a curved course.

Here and preferably, the damping ears 2 B each integral with the body 2a educated. In particular, the damping ears exist 2 B from the same material, or the same foam, plastic or rubber, as the body 2a , As already indicated, the damping tubes can 2 B but also, especially in single or multi-component injection molding, to the body 2a be sprayed. It should again be noted that the main body can also be formed by the jacket of a Bowden cable.

As the 1 and 3 show the muffling ears 2 B in the direction of the longitudinal axis L here and preferably a smaller extension than the main body 2a , Also have the damping ears 2 B a smaller extension in the direction of the longitudinal axis L as transverse to the longitudinal axis L or as in the circumferential direction U , Here and preferably, the damping ears 2 B disc-shaped. damping ears 2 B With such a small thickness increase the flexibility and flexibility of a support element 2 and an actuator assembly 1 of the type described above.

The damping ears 2 B are here and preferably around the longitudinal axis L around, in particular at regular angular intervals arranged. In the circumferential direction U the muffling ears are aligned 2 B to each other. Furthermore, the damping ears 2 B here and preferably identical in shape and in particular in each case mirror-symmetrically with respect to a plane e ' formed by the longitudinal axis L extends.

The 3a) and b) further show that the proposed support element 2 a slot 10 may have, which is parallel to the longitudinal axis L through the support element 2 and in particular the main body 2a extends. In the embodiment according to 3a) is the slot between the two 10 forming material surfaces a gap 11 educated. In the embodiment in 3b) they are the slot 10 forming material surfaces interlocked, causing a bending of the body 2a prevent in the assembled state. In particular, such a hooking allows the support element 2 by positive connection under tension to an actuating element 3 , or a Bowden cable, create and hold.

3b) Finally, shows an embodiment of the support element 2 in which the damping ears 2 B are punched. Alternative to such holes 12 for example, depressions may also be provided. In this way, the damping properties of the support element 2 improved.

According to another teaching, which has independent significance, the actuator assembly 1 claimed as such. On all versions of the proposed support 2 that are suitable, the actuator assembly 1 to explain, may be referenced.

An interesting aspect of the proposed actuator assembly 1 is that on an actuator 3 more than two, in particular more than three, proposed support elements 2 can be provided, which is exemplary in 4 is shown.

According to yet another teaching, which also has independent significance, a motor vehicle component is claimed as such, which is a proposed actuator assembly 1 having. In this case, the actuating element arrangement forms 1 For example, a mechanical connection between a door handle and a motor vehicle lock. The cable 8th may for example be part of an electrical monitoring or control of the motor vehicle lock, a window regulator drive or the like. The motor vehicle component may also be a module of a motor vehicle door or the like, which may be equipped as explained above.
