Austrian Patent Office AT 508 351 B1 2011-01-15

The invention relates to a damping unit according to the preamble of claim 1. Furthermore, the invention relates to a foldable additional plate according to the preamble of claim 19. Finally, the invention relates to a table with a table top extending or magnifying, foldable and a Twist axis on the table on and swing out mounted additional plate.

Damping units are known from the furniture industry; with these, the mutual movement of components, such as the door of a box or a folding caches with respect to the body is damped or cushioned.

From AT 008110 U1 and AT 500895 B1 tables with a table top are known, which are extendable with an additional plate. This additional plate is formed by two plate parts which are hinged together. In this case, a first plate part of the additional plate is mounted on the frame of the table and the additional plate is in its folded position below the table top. As soon as the additional plate is pulled out under the table top and unfolded in the course of a pivoting, it extends the table top. The two plate parts are pivotable about a common pivot axis. After enlargement of the table frame and lateral extraction of the additional plate, the two plate parts forming the additional plate are pivoted about the pivot axis while the additional plate unfolds or opened. In this case, a guide of the additional plate or the two free ends of the plate parts is such that they do not collide with the table frame. For this purpose, a corresponding sliding guide is arranged on the additional plate, which cooperates with a table-side support. When unfolding the plate parts in their final position, ie in the table level, adjusted.

Such an arrangement has the disadvantage that the additional plate when pivoting in its end position in which it extends the table top, in particular because the plate part, which is taken to operate the additional plate by hand, sometimes can not be well held on The table frame or provided for the plate part supports fall down, which can lead to noise on the one hand, but also to damage the table and the mechanism. The same applies to the folding of the additional plate. As soon as the two plate parts approach one another during folding, it may happen that the hand-held plate part of the hand slips off and falls onto the other plate part. This can also damage the table and on the additional plate and on the mechanics occur.

The aim of the present invention is to achieve a damped or cushioned opening and closing of the two plate parts of an additional plate or to create a suitable damping unit. The critical movements, namely the complete folding and the complete unfolding of the two plate parts, to be defused or cushioned.

According to the invention this is achieved in a damping unit of the type mentioned above in that the damping element comprises a first damping member and cooperating with this second damping component, which damping components are aligned in series with respectively opposite damping direction or effect characteristics for acting on them loads. The damping unit is double-acting; the first damping component brakes acting train, the second damping member brakes applied pressure.

Due to the inventive design of the damping unit ensures that both the collapse and the complete unfolding of a two mutually pivotally mounted components comprehensive arrangement, the end of the respective movement of these components is damped. Such a damping unit is simple and manufactured with known damping components. It is advantageous here if gas or oil pressure dampers, preferably hydraulic brakes, are used as damping components. Such damping components, in particular hydraulic brakes, provide the required forces and / or show a suitable damping or cushioning characteristic. By selecting the damping characteristic, in particular by selecting the size of the overflow openings for the hydraulic fluid, the damping components can be adapted to the different conditions, in particular size and weight, of the components to be spring-loaded.

Such damping units can be used for any arrangements of mounted around a common pivot axis components. Both when folding and when completely unfolding the components in a plane can be cushioned or damped with the damping unit according to the invention, the respective end movement, so that sudden movements of the components are avoided.

In the dependent claims preferred developments of the invention are described in more detail: In a preferred embodiment of the invention, it is provided that the mutually facing ends of the two damping components are guided relative to each other movable or guided slidably mounted and against each other and at abutting ends of the damping components in the final stage of deployment or in the initial stage of folding of the one damping component from the other damping component is at least partially compressed. The two damping components, which form the damping element, cooperate, in particular in the event that the two components are wasted in their open end position.

For the damping of the folding of the components, it is advantageous if the first damping member pivotally mounted with a first end attachable to one of the components first mounting part and the trajectory of its second end in its the first fastening part remote end portion with the second Damping member end limited by the second end of the first damping component is compressible.

In order to obtain an exact sequence of movements, it is provided that the first damping member is pivotally and slidably guided with its end in a guide and the first end of the second damping member projects into this guide. It is quite expedient that the second damping component with its end or with their provided at the end of its control rod guide pin in the guide, in particular for the entire compression path of the actuator or piston rod, is guided out adjustable.

It is structurally simple if the guide and the second fastening part are formed in one piece or on the same fitting part. However, it is also quite possible to form the guide and the fastening part for the second damping component as separate fitting parts. It is essential that the second damping component or its end associated with the first damping component is positioned relative to the guide such that the end of the first damping component guided in the guide can be applied to this end or the control rod of the second fastening component.

To allow a Verschwenkweg the plate members or attached to these fasteners without collision of the first attachment part and the first damping member with the plate parts and to achieve a corresponding geometry of the damping unit, both during folding and during deployment the corresponding damping in Ensures the respective end movement, it is provided that the guide, starting from its the first fastening part near end region over a predetermined distance with respect to its base surface or base plane, which faces this assembly when mounting the damping unit on a building or plate part, this is inclined away from this base plane in that an approximately equally long, oppositely inclined track section adjoins this track, and that a section of the track running parallel to the base plane adjoins this track section.

A simple structure of the guide results when it is provided that the guide comprises two opposing, parallel and perpendicular to the base plane webs or cheeks, in each of which the same guideway is formed, of 2/19 Austrian Patent Office AT Each guide track is received and guided the end of a guide pin fastened to the second end of the first damping component and optionally the end of a guide pin fastened to the first end of the second damping component or its actuating rod.

The noise and frictional resistance occurring during the displacement of the guide pin of the first damping component, possibly also of the second damping component are reduced when sliding sleeves, in particular made of plastic, are placed on the ends of the guide pins protruding into the guide track.

In order to achieve an interaction of the two damping components and to optimize the damping, it is provided that the direction of action of the second damping component is in the same plane and optionally in alignment with the second end of the first damping member issued by the guide movement direction.

Contributes to also when the second fastening component and the first damping member are mounted in the same plane against each other pivotally and in the use position and the first damping member mounted on the first fixing member is pivotally mounted in this plane.

It is advantageous if the guideway and pivotally mounted in this first damping member defines a pivot plane in which the first damping member is pivotable relative to the guideway and the mounting or base surfaces of the two lying in this plane fasteners with each other directly opposite Fasteners facing each other.

Since the second damping component is intended to achieve a cushioning of the first damping component and of the plate part connected thereto, it is provided that the actuating rod or piston rod of the second damping component is moved from a spring unit into its initial position, d. H. is pressed in the non-compressed position of the damping component.

A simple structure to enable the second damping member after a cushioning of the unfolding and its compression back to its initial state in which it can cushion an unfolding, provides that the second damping member is surrounded by a compression coil spring, with their one end is fixed in the guide-remote end region or on a support of the second fastening part located there and is connected at its other end to the end region of the projecting actuating rod or piston rod of the second damping component, the helical compression spring acting as a return spring for the actuating rod or piston rod these are pressure-loaded against their compression direction in their extended position.

It is further provided that the geometry of the damping unit is selected such that in the course of the final movement during deployment in aligned in series fasteners the two damping components are also aligned in series and the actuating or. Piston rod of the first damping member is in the retracted final state at the beginning of its extension or damping travel and the first damping member presses against a the actuating rod or piston rod of a stop damper second damping member which is at least partially compressed and the unfolding of the Panel parts cushioned by its compression. Thus, in particular, the end movement during deployment of the plate parts is cushioned.

In order to ensure that in folded plate parts and a failed attempt to lift a plate member damage to the plate parts or the pivot mechanism are avoided, it is provided that any movement that opens folded plate parts, immediately a provision of the first damping component or his control rod in operative position result, that is a retraction of the actuating rod or piston rod in their damping ready position. It is envisaged that directly at the beginning of the guide in this or in the two guideways, a receptacle or depression for supporting or retaining the arranged at the second end of the first damping member guide pin is formed, which recording or depression via a Gleitnase or a Höker in the subsequent 3/19 Austrian Patent Office AT 508 351 B1 2011-01-15 guideway or route passes. This means that for a certain period of time, provided at the end of the first damping member guide pin is in the recess or retained by the Höker. Upon further deployment, the guide pin slips or slides over the hanger and moves along the guideway, wherein the actuating or. Retracted piston rod in the damping member and the first damping member is tensioned without the damping member while the adjusting or piston rod opposes significant resistance. At the moment, however, in which the two plate parts, for whatever reason, approach each other, the adjusting or piston rod of this movement provides corresponding resistance or absorbs this movement.

In order to achieve a support of the first damping member, in particular to counteract the folding of the plate parts of a bend, it is provided that in the first damping member near end portion of the second fastening part support parts, in particular in the form of the cheeks of the guide to both sides bent flanges, is formed.

A structurally simple structure is obtained if designed for the end of the second damping component support or support and the cheeks of the guide as separate components or integrally formed or on the same fitting component, in particular a stamped component lie.

A foldable additional plate with two foldable over a common pivot axis or pivotally interconnected plate parts, in particular for the extension of table tops, according to the invention is characterized in that on one of the plate parts of the additional plate in one of these pivot axis of the plate parts near area of the first fastening part and on the other plate part in a region close to this pivot axis, the second fastening part is fastened.

With the invention in the use position of the unfolded additional plate located on its underside damping unit, both the final movement during folding and the final movement when unfolding the plate members are attenuated in a table top extending surface. Depending on the size of the additional plate or thickness of the inserted plate parts, the dimensions of the fasteners and the damping components are determined.

A simple construction results when a single damping component is arranged in the longitudinal center of the two plate parts common pivot axis.

An exact guide or damping is obtained when the pivoting plane defined by the first damping component and the second fastening part in their mutual movement is perpendicular to the common pivot axis of the plate parts.

In order to ensure a corresponding geometry in which the damping components do not collide with the end faces or end edges of the plate parts during pivoting of the plate parts, no matter in which position the plate parts are located, it is advantageous if a bearing for the first damping component supporting portion of the first attachment part and the initial region of the guide project beyond the lying in a plane end faces of the two plate parts in the folded position of the additional plate and a connecting line from the bearing to the beginning of the guide or located at the beginning of the guide recess at an angle of 20 to 40 ° runs to the end faces of the two plate parts.

In such an additional plate when folding the first damping member in the final stage of folding the plate members is loaded to train and counteracts the folding. At the beginning of unfolding the control rod is pressure-loaded, since the first damping component with its guide pin comes to lie in the receptacle and thereby the control rod is reset. Furthermore, in the open position of the folding plate, the adjusting rod or piston rod of the second damping component is adjusted or pressed by the second end of the first damping component against the force effect of the second damping component into an at least partially retracted position. This results in an effective damping of folding occurring during folding or unfolding of the additional plate end movements and apart from the convenience and responsive gentle adjustment or pivoting of the additional plate takes place a conservation of the mechanics and the table construction.

An exact guidance of the plate parts is given when the base or mounting surfaces of the two fastening parts lie in the folded end position of the additional plate opposite each other and parallel to each other and in the open end position of the additional plate in the same plane.

Finally, the invention relates to a table with a table top extending or magnifying, foldable and about a rotation axis on the table and swing-mounted additional plate. Such inventively formed additional plate with a damping unit according to the invention results in a table with plate parts or an additional plate whose operation is gentle, almost noiseless and easy, especially in the respective end movements.

An advantageous in terms of construction, construction and operation table results if it is provided that the pivot axis of the mounted on the additional plate mounting parts of the damping unit is perpendicular to the axis of rotation about which the additional plate for pivoting and pivoting is mounted on the table, and / or the first fastening part is fastened on the plate part of the folding plate with which the folding plate is pivotably mounted on the table about the axis of rotation, this plate part preferably lying in the table pivoted position of the additional plate above the other plate part. An advantageous damping characteristic of a table is obtained if it is provided that the second end of the first damping component is pressed or pressed against the supported on the second fastening part second damping member with fully expanded auxiliary plate and this damping member is at least partially compressed and that in the final movement of the Folding the adjusting rod against the damping effect of the first damping component is pulled out of these or in folded plate parts of the first damping member is adjusted against a force exerted by him damping or force effect in its end position.

In the following, a particularly preferred embodiment of the invention with reference to the drawing, for example, explained in more detail.

Fig. 5 shows in different views a damping unit according to the invention in a position in which the two plate parts connected to each other with a common pivot axis are in fully unfolded position.

Fig. 6 shows an oblique view of a partially unfolded additional plate.

Fig. 1 shows an advantageous embodiment of a table 39 according to the invention having an additional plate 40 according to the invention with a damping unit according to the invention.

The table with additional plate is of known type, as described for example in AT 500 895 B1. Such a table or its additional plate can be equipped with at least one damping unit according to the invention. In itself, it is possible to dampen differently designed tables and other ways in a table pivotally mounted additional plates in the manner according to the invention in their movement. Such a table 39 comprises a rectangular frame 41, which is provided at its corners with four legs 42 which support the table top 32. The frame 41 comprises two U-shaped frame parts 51, 52, which are mutually displaceable or each other. The table 39 is shown in a position in which the two frame parts 51, 52 are in the extended position. Thus, located in the retracted position of the frame members 51, 52 below the table top 32 additional plate 44 which is pivotally mounted on the frame part 52 about a provided in this horizontal axis of rotation 46 with pivot bearings 45, folded and pivoted in the plane of the table top 32. The additional plate 44 comprises two plate parts 30, 31 pivotably mounted about a common pivot axis A. The pivot axis A lies in the region of two adjacent edges of the respective end faces 38 of the two plate parts 30, 31.

The additional plate 40 is pivotally mounted with its upper plate member 30 in the frame or on the extendable frame part 52 about the axis of rotation 46. The second plate part 31 is guided with a guide rod 48 in a formed in a arranged below the table top 32 support 50 pivot guide 47 to make the pivoting or swinging out of the additional plate 40 defined.

In the region of the pivot axis A, with which the two plate parts 30, 31 are pivotally connected, a damping unit 60 according to the invention is arranged, which is indicated only schematically in Fig. 1 and 2, 2a, 2b and 2c.

In Fig. 6, the damping unit, which is fixed to the two plate parts 30, 31 with fastening parts 1, 2, shown. The first fastening part 1 is fixed to the plate part 30, in particular screwed. The second fastening part 2 is attached to the second plate part 31, in particular screwed. The second fastening part 2 comprises a guide 14, in which a first damping component 3, which is pivotally connected to the first fastening part 1, slidably guided and pivotable. A second damping component 4, which projects into the movement path of the first damping component 3, can cushion a movement of the first damping component 3.

2, 2a, 2b and 2c, the unfolding and folding of the two plate parts 30, 31 is explained in more detail. In Fig. 2, the additional plate 40 is below the table top 32. The plate members 30, 31 lie with their use surface together. The damping component 3 of the damping unit 60 is in a relaxed state, i. a retraction of the actuator or piston rod 21 in the damping member 3, no resistance is opposed. The position of the damping unit 60 in this state is shown in Fig. 4. The adjusting rod 21 of the first damping component 3 can be applied without force to be retracted into the damping component 3. The extended control rod 22 can be retracted against the damping effect of the damping member 4 in this.

The frame part 52 carries the axis of rotation 46 about which the auxiliary plate 40 is pivotable in its position of use. With a support 44, the free end of the additional plate 40 and the plate member 31 are supported.

The second plate member 30 is located at retracted additional plate 40 above the plate member 31. When lifting the plate member 30 of FIG. 2a this is removed from the plate member 31. The plate member 31 is thereby displaced with a slide guide 56 attached to it via a support 55, which causes the free end 61 of the plate member 31 from the recess in which the additional plate 40 is arranged, moved out and above the frame members 51, 52nd to come to rest.

Upon further pivoting of the second plate member 30 in the direction of arrow 57, the additional plate 40 enters the position shown in FIG. 2b. In this position, the damping unit 60 begins to act and counteracts further movement apart of the plate members 30, 31 and attenuates the Auffaltbewegung to cause a gentle unfolding of the additional plate. In this position, the second end of the first damping member 3 meets the extended control rod 22 of the second damping member 4. The first damping member is attached to the upper plate member 30, the second damping member 4 is fixed to the lower plate part 31.

In Fig. 2c, the additional plate 40 is shown in its unfolded end position. In this end position, the second damping component 4, as shown in FIG. 5, is compressed and loaded, after it has begun to act in the position of the auxiliary plate 40 near the end position shown in FIG. 2 b.

The second damping member 4 thus supported due to its tensioned state at the beginning of folding the plate members 30, 31, the lifting of the plate member at the beginning of the Einschwenkvorganges the auxiliary plate 40. When pivoting the process proceeds as shown in Figs. 2, 2a , 2b and 2c, in the reverse direction. Shortly before the two plate parts 30, 31 reach their folded end position, as shown in Fig. 2, wherein the upper plate member 30 rotates against the arrow 57 about the pivot axis 46, the first damping member 3 starts to act and attenuates the folding movement the plate parts 30, 31. The retracted in the unfolded position of the plate members 30, 31 in the first damping member 3 actuating rod 21 is braked by the damping member 3 during withdrawal and thus the end movement of the plate members 30, 31 is attenuated during folding. In the position shown in FIG. 2, the control rod 21 of the damping member 3 is relieved and could be reset without force. The second damping component 4 and its control rod 22 are also relieved and the control rod is extended and is available for further damping or compression available.

FIG. 3 shows a damping unit 60 according to the invention with its individual parts. A first fastening part 1 can be fastened to the first plate part 30 with a fastening surface 12 or fastening straps formed on it. The fastening takes place in such a way that - as shown in FIG. 4 - the recess 26 situated in the end region of the fastening part 1 or the pivot bearing for the control rod 21 overhangs the pivot axis A or the end faces 38 of the two abutting plate parts 30, 31. In these recesses 26 are plug pin 7 for receiving or holding a guide pin 25 can be inserted, which guide pin 25 is pivotally mounted in the recesses 26. The guide pins 25 are based on a transverse web 28, which is connected to the free end E1 of the first actuating or piston rod 21, which is part of the first damping component 3. The damping component 3 sets the withdrawal of the actuator or piston rod 21 resistance. The piston rod distal end E2 of the damping member 3 is connected to a guide member 6 by a threaded bolt 27 is screwed into a corresponding mating thread on the guide member 6. The guide member 6 has guide pins 25 which are received by a guide or guide track 14. On the guide pin 25 sliding sleeves 23 can be placed.

The guide 14 and its cheeks 29 are shown as part of the second fastening part 2. The second fastening part 2 can be made in one or two pieces. The guide 14 can be fastened as an individual part or independent component to the surface of the second plate part 31 lying down in use. This item is then supplemented with an independent support 20 for the end E4 of the second damping component 4. In Fig. 3, the guide 14 and the support 20 are shown as a one-piece stamped component. The guideway 14 is located in opposite cheeks 29, so that a stable sliding guide is provided for the two guide pins 25 of the first damping member 3. Advantageously, the guide pins 25 of this damping component 3 in the guide 14 are also mounted pivotably. In principle, it could be provided that the free end of the control rod 21 is rotatably mounted in the guide member 6.

The cheeks 29 of the guideway are connected via a serving as a mounting surface 13 wall, with which the second fastening part 2 can be fastened to the plate 31. Supports 15 support the front end of the guide 14 and the cheeks 29, which protrude beyond the end faces 38 of the folded plate parts 30, 31, as shown in Fig. 4. The second fastening part 2 comprises the support 20, which is connected to the end E4 of the second damping component 4, for example by screwing by means of a screw 8. The damping component 4 comprises the second actuating or piston rod 22, which is shown in its unloaded initial state in FIG. An insertion of the actuating rod or piston rod 22 of the damping member 4 provides resistance. At its free end E3 the adjusting or piston rod 22 carries a contact washer or a spring holder 5 for a compression spring 4 surrounding coil spring 9. This compression spring 9 may be supported on the bend 20 as well as the damping member 4 and presses the actuating or Piston rod 22 in the direction of its extended position. The free end E3 of the actuating rod or piston rod 22 carries a further guide part 6 ', which is displaceably guided in the guideway 14 with guide pins 25 optionally provided with sliding sleeves. At the front end portion of the guide member 6 ', a damping member 24 may be fixed to cushion a juxtaposition of the guide members 6 of the first damping member 3 and the other guide member 6'. Such a guide component 24 can also be arranged on the guide part 6.

The guide track 14 has in its rear, the pivot axis A with the two plate members 30, 31 are connected, remote end a mounting recess 19. The front end portion of the guide 14 is shown enlarged in Fig. 3 below. One recognizes the guideway 14, which has a receptacle 33 for the guide pins 25 of the first damping component 3 in its uppermost end region or merges via a hanger 34 into a first section 16 of the guide 14. This bracket 34 serves to briefly lock or stop the guide pin 25 at the beginning of Auffaltbewegung and hinder further movement of the end E2 of the damping member 3 until the first damping member 3 at least partially tensioned or by retracting the control rod 21st is at least partially, preferably completely, adjusted in its damping position.

The guideway 14 has one of the pivot axis A near a distance 16 which is inclined and in a direction away from the plate member 31 direction. To this route includes a section 17 with substantially opposite slope. This section 17 is followed by a section 18 in which the guide track runs essentially parallel to the attachment surface 13 or to the surface of the plate part 31 on which the second attachment part 2 is mounted.

Fig. 4 shows the damping unit 60 according to the invention in a state of the plate members 30, 31, in which they lie against each other, that is in the initial position of the unfolding or in the end position of the folding. The first fastening part 1 is fastened to the upper surface of the first plate part 30 lying in the position of use of the additional plate. The bearing recess 26 for the control rod 21 of the first damping member 3 projects beyond the pivot axis A. The damping member 3 with its control rod 21 extends at an angle of about 20 to 40 ° inclined to the end faces 38 of the plate members 30, 31. The guide pins 25 are in the The guide part 6 'on the adjusting rod 22 of the second damping component 4 is in the extended position, in which it is adjusted with the compression spring 9.

When lifting the plate 30, the control rod 21 is moved without substantial resistance in the damping member 3 and at the latest when the control rod 21 comes into its retracted end position, the guide member 6 slides due to the pressure exerted on it and the changed direction of it exerted pressure on the Höker 34 of the recess 33 in the guide 14th

When, after lifting the plate member 30, this plate member 30 approximates the plate member 31, e.g. When the plate member 30 slips off the user's hand, the damping member 3 is already in its pre-tensioned damping position and counteracts the actuating rod 21 from coming out, thus cushioning the approximation of the plate member 30 to the plate member 31.

In a further pivoting of the plate member 30 according to arrow 57 in Fig. 2a, the guide pin 25 of the guide member 6 slides in the guideway 14 until the guide member 6 on the guide part 6 'of the second damping component 4 meets. This position is achieved when the plate members 30, 31 are in the position shown in Fig. 2b. In this position, the guide member 6 of the first damping member 3 loads the control rod 22 of the second damping member 4 and pushes them into the damping member 4 against the resistance offered by this damping member 4. Thus, the further movement of the plate parts 30, 31 in their aligned end position, as shown in Fig. 2c, counteracted or cushioned this movement. In Fig. 5, the end position of the two plate parts 30, 31 shown in FIG. 2c. The damping component 3 is in the tensioned starting position and counteracts pulling out of the control rod 21. The damping component 4 is in its compressed position and makes a further retraction of its control rod 22 resistance.

If lifting of the plate part 30 takes place in this position, then the damping component 3 moves away from the damping component 4 and the control rod 24 emerges from the damping component 4 due to the force action of the spring 9. However, if this plate member 30 is dropped again, for example because it slips off the user's hand, the damping member 4 has already been adjusted to its cocked position by appropriate extension of the second control rod 22 by the action of the compression spring 9, and it may drop the panel member 30 Immediately be counteracted a corresponding damping resistor. The first damping member 3 remains in this fully retracted position during this process.

It will be noted that in place of plate members 30, 31 of an auxiliary plate 40 any other plate members may be damped in their movement, between a movement in which the plate members or attached to these plate parts fasteners in a first Starting position, as shown in Fig. 4 and to be adjusted in an end position in which the fastening parts in an extended position, as shown in Fig. 5, are located. Such components may be folding doors, box doors, swivel plates for consoles, worktops, chests, covers or the like. It is also entirely possible that the starting position of the two fastening parts is such that the two fastening parts do not run essentially parallel to one another but enclose an angle. The fasteners should project beyond the pivot axis A, since in the course of the pivoting due to the thickness of the components or the plate parts 30, 31 care must be taken that when folding and unfolding the first damping member 3 with its control rod 21 around the edge K of the second Part of the plate can be guided around.

As spring units or instead of the damping member 4 surrounding coil spring 9, any spring units can be used, which adjust the control rod 22 of the damping member 4 in its extended position. It is also possible, for example, to use spiral tension springs in the area in front of the control rod 22 or also spiral compression springs which are mounted between the head of the damping component 4 and the guide part 6 '.

The inner spacing of the cheeks 29 of the guide 14 is selected such that the first fastening part 1 and the first damping member 3 can penetrate during the deployment of the auxiliary plate 40 in the space between the cheeks 29.

The term "action characteristic" is understood to mean the direction of damping components, in particular of hydraulic springs, in which they counteract the effects of forces or forces exerted on their adjusting rods.

It is not absolutely necessary that the adjusting rod 22 of the second damping component 4 is guided in the guide 14. It is sufficient that the adjusting rod 22 sufficiently provides resistance to the end E2 of the first damping member against its adjustment without dodging. It could thus be provided a separate guide for the control rod 22.

In principle, it is also possible to arrange the individual or both damping components in each case rotated by 180 °, since thus the same damping effect can be achieved. The 9/19
