Description

Device for adjusting and locking a structure, e.g. B. connectable to a floor of a means of transport or means of transport

The invention relates to a device for adjusting and / or locking a structure, e.g. with a floor of a means of transport or means of transport, in particular for a motor vehicle, a motor home, an aircraft, a rail vehicle, a ship or the like, with the features mentioned in the preamble of claim 1.

It is known to adjust vehicle seats in the longitudinal direction by means of rotatable rollers connected to them, and to lock them in the desired position by means of suitable components.

DE 36 42 441 C1 describes a roller guide for a vehicle seat, which consists of a C-profile-shaped seat rail, within which a roller is movably arranged. A rotatable auxiliary roller is provided axially parallel to the first roller, with the dimensional one

Tolerances of the seat rail should be compensated.

Another guide for adjustable vehicle seats is known from DE 195 19 153 A1. It is provided that the guide rail has at least two guide areas which are separated from one another by a central web. DE 196 48 170 C1 contains a guide device for vehicle seats in which the running rail has an upper and a lower running track. A rattle-free running of the rollers within the C-shaped running rail is to be achieved by means of an elastic ring which is arranged on the running roller.

EP 0 765 776 A2 provides a roller guide for a longitudinally adjustable seat, which is designed in such a way that it is smooth-running and not susceptible to contamination and that stable and secure lateral guidance is provided. The roller guide has two partial running surfaces, a groove-like depression being arranged in the guide rail in the region between the partial running surfaces. In addition to the sliding roller, a pressure roller is provided, both of which are made of

Plastic. On the one hand, these solutions mentioned are intended to ensure the movement play necessary for a necessary displaceability of the seat and, on the other hand, to compensate for manufacturing-related tolerances of the guide rails. The manufacturing tolerances of the rails lead to rattling noises in motor vehicles, which are partly eliminated according to the prior art by interposing elastically deformable rollers or the like between the profile rails, which undergo material compression when the seat is loaded and the profile rails in again when the seat is relieved press their upper contact position.

A roller guide is known from US Pat. No. 5,348,261, which has a guide rail formed from a hollow profile with a running surface for two sliding rollers arranged at a distance from a seat frame, as well as a pressure element for the sliding rollers. The pressure element is slidably arranged on the inside of the upper profile wall opposite the running surface and the sliding roller is acted upon by a mounting arm in the direction of the running surface. With this roller guide, accumulated dust and dirt particles adhere to the tread and impair their ease of movement up to blocking the seat adjustment.

The disadvantages of this known device for adjusting and locking a vehicle seat essentially consist in the fact that it is relatively complex to implement. Furthermore, due to dirt particles penetrating the guides, it tends to become stiff in the direction of displacement and does not allow the vehicle seat to be locked without play, which can cause rattling noises inside the vehicle during driving.

All of the above-mentioned devices do not solve the problem of ensuring a permanent smooth movement of a seat or another structural unit of a vehicle. They are also complex in the assembly and disassembly of a seat or another structural unit to be connected to the vehicle floor. The great effort for assembly and disassembly is due in particular to the fact that the structural units can only be inserted into and removed from the guide rails in certain areas in which the guide rails have recesses. In the case of vehicle seats, their arrangement within the vehicle inevitably results in a specific sequence for the assembly and disassembly of the seats. Another disadvantage of the known solutions is that the functions of the guide rails are aimed exclusively at adjusting and locking components and therefore do not permit any other use. From US Pat. No. 5,937,706 a device for adjusting and locking a structural unit on a structural element, preferably a floor of a means of transport, is known. This structural unit is displaceably arranged within guide rails assigned to the construction element, locking being carried out by means of a clamping device. Here, clamping jaws are pressed against contact surfaces of the guide rail by means of a manually operable fixing element. This creates an essentially linear contact between the contact surfaces of the clamping jaws and the contact surfaces of the guide rail. There is therefore a risk that if the clamping force decreases, for example due to vibration or the like, a firm fit of the assembly is not guaranteed within the guide rail. The assembly can thus be displaced from its position by forces acting in the longitudinal direction of the guide rail.

It is also known that vehicle seats, in particular integral seats for passenger compartments, in the

Crash case are exposed to significant dynamic loads. For this reason, their load-bearing components are designed according to the requirements, which leads to a considerable weight of the seats. In particular, if additional restraint systems are available, their attachment requires additional point-specific screw connections to a vehicle floor in order to be able to absorb the forces that occur.

The invention has for its object to provide a device for adjusting and locking a connectable to a structure such as wall, floor or the like unit of a means of transport or transportation of the type mentioned, in particular integral seats that smooth adjustment and a safe and play-free

Locking of a structural unit of a means of transport or means of transport is ensured and, at the same time, simple assembly and disassembly of the structural unit is possible at any point on the guide rails, and also creates the conditions for a multifunctional use of the guide rails, such as e.g. the non-positive and form-fitting connection of seat belts, tension belts or holding elements, is characterized by a weight-saving structure and causes reduced punctual loads on the structure in the event of a crash and is simple and therefore inexpensive to manufacture and has a high level of stability.

This task is performed by a device for adjusting and locking one with a

Structure, for example a floor of a means of transport or means of transport, can be connected with the features mentioned in claim 1. Characterized in that the clamping device has at least one clamping jaw, the contour of a contact surface of the have at least one clamping jaw and the contour of a contact surface assigned to the contact surface of the guide rail corresponding shape features that allow a precise locking, an easy adjustment and a safe and play-free locking of a unit of a means of transport or transportation is guaranteed and at the same time its simple assembly and disassembly on one enables any position of the guide rails. The smooth adjustment of the assembly is advantageously realized by means of at least one roller. The secure and play-free locking of the assembly is advantageously ensured by at least one clamping device. The assembly and disassembly of the assembly are possible at any time in a simple manner. It is particularly advantageous that the assembly can be removed and used at any point on the guide rails. In particular, the corresponding shape features make it possible to establish a positive connection between the structural unit and the guide rails. This ensures a secure and play-free position fixation of the structural unit. The positive locking essentially remains intact even when the clamping forces decrease slightly, so that it is impossible to move the structural unit in the longitudinal direction of the guide rails.

It is within the scope of the invention that the structure which has the guide rails can also be a pallet or the like platform.

The connection of seat belts and adaptive restraint systems, e.g. Belt tensioners or belt force limiters, to the seat base frame and their force introduction resulting in the connection of an extended clamping length locking in the guide rails, includes the introduction of different force vectors into the seat rails in the event of a crash, distributed over the entire length of the seat, or even beyond. As a result, the seat and the structure have reduced point loads and thus lower demands on its load-bearing components. The weight of the seats can be reduced, manufacturing costs minimized and the payload increased.

Furthermore, instead of external fixed lashing eyes or fastening points, lashing straps or holding elements can be non-positively fixed in the guide rails at any point, e.g. for securing goods or the like in transit. But also the transportation or delivery of the vehicle seats themselves.

In addition, the guide rails with the arrangement of electrically conductive elements can advantageously be used in a multifunctional manner. The multifunctionality of the guide rails offers in particular the possibilities of using the guide rails To use power supply, for example for an electric motor, as well as for communication and data transmission purposes.

In a preferred embodiment of the invention it is provided that four assemblies are arranged on the base frame of the structural unit, which are connected on both sides to the base frame, in each case in a region near the front and near the rear end of the base frame. This arrangement of the four assemblies advantageously enables the structural unit to be moved easily and securely fixed in position.

In a further preferred embodiment of the invention it is provided that in each case positive connections can be made between the structural unit and the guide rails via the clamping device. This ensures a secure and play-free position fixation of the structural unit.

Furthermore, it is provided in a preferred embodiment of the invention that the clamping devices each have at least one clamping jaw, the contour of the contact surface of the clamping jaw being designed such that it corresponds to the contour of the contact surface of the guide rail. In this advantageous manner, a form-fitting fit between the two parts is achieved.

The device according to the invention can also be used for fastening an object or the like to a statically fixed structure.

Further preferred configurations of the invention result from the other features mentioned in the subclaims.

The invention is explained in more detail below in exemplary embodiments with reference to the associated drawings. Show it:

In the eighteen figures, the individual parts and assemblies of the device according to the invention are shown schematically and only with the components essential for the invention. Identical parts of the device according to the invention are provided with the same reference symbols in the figures and are generally also only described once.

Figure 1 shows an assembly of a first embodiment of the device according to the invention. The assembly shown of the invention

The device essentially consists of a roller 14 and a clamping device 18, which are each arranged on the base frame 10 of a structural unit. In a preferred embodiment of the invention, four of the modules shown are arranged on a base frame 10 of a structural unit to be connected to the floor 20. A vehicle seat that is within such a unit is particularly suitable

Guide rails 12 to move and lock. According to a preferred embodiment of the invention, it is provided that the assemblies 19, consisting of roller 14 and clamping device 18, are connected on both sides to the underframe 10, near the front and near the rear end of the underframe 10. The assembly can be displaced within the guide rails 12, which are connected to the floor 20, via the rollers 14. As a rule, the unit is moved manually. According to a preferred embodiment of the invention, it is provided that the rollers 14 are optionally connected to an electric motor 22, by means of which the rollers 14 can be driven and the assembly can be moved by an electric motor. The clamping device 18 serves to lock the structural unit within the guide rails 12.

Furthermore, it can be seen in FIG. 1 that the clamping device 18 is connected to a cable pull 50, which leads via a deflection roller 38 to an actuating unit 30 shown in FIGS. 7 and 8. FIG. 2 shows a section across the guide rail 12 and the roller 14 according to FIG. 1. The roller 14 is rotatably mounted on the base 10 of the assembly and is supported on the tread of the guide rail 12. Furthermore, this illustration shows the design of the guide rail 12 and its attachment to the floor 20. In this preferred exemplary embodiment of the invention, the guide rail 12 is symmetrical in cross section and has a T-groove in the profile. The guide rail 12 is fastened to the base 20 by means of screw connections, which are implemented here by means of countersunk screws 28. The guide rail 12 has prism guides 16 on both sides of the T-profile, which serve to accommodate electrically conductive elements in the form of conductor tracks 26. These conductor tracks 26 can advantageously be used in a multifunctional manner. For example, they can be used to supply power to an electric motor 22. It is also possible to use them for data transmission and / or communication purposes.

Figures 3 and 5 show the guide rail 12 and clamping device 18 shown in Figure 1 each in different sectional views. In FIG. 3 the section runs longitudinally through the guide rail 12 and the clamping device 18 and in FIG. 5 the section runs transversely through the guide rail 12 and the clamping device 18.

The clamping device 18 has a symmetrical basic structure and is fastened to the base frame 10 of the structural unit. It essentially consists of two clamping jaws 48 pivotably mounted on the base frame 10 about axes 47, between which a fixing element 52 which can be changed in its vertical position is arranged. By changing the position of the fixing element 52, two working positions of the clamping device 18 are realized, one of which is the locking position, in which the clamping device 18 is positively connected to the guide rail 12, and the other is the open position, in which the clamping device 18 of the Guide rail 12 is released.

According to the representations in FIGS. 3 and 5, the clamping device 18 is in the locking position. The fixing element 52, which is acted upon by the force of a compression spring 44, is in its lower position, in each case pressing the two clamping jaws 48 outwards and holding them in a form-fitting manner with the guide rail 12. The fixing element 52 is constantly held in this position by the force of the compression spring 44, which is arranged around a guide pin 46, and thus the positive engagement of the two clamping jaws 48 with the guide rail 12 is maintained as long as no force in the direction of the arrow 51 according to FIG 3 acts on the cable pull 50. The contact surfaces 60 of FIG

Guide rail 12 and the contact surfaces 62 of the clamping jaws 48 advantageously have corrugated contours which correspond to one another (FIG. 4). This advantageous design of the contours of the two contact surfaces 60, 62 results in a form-fitting fit and thus a stable position fixation of the structural unit.

The positive connection between the contact surfaces 62 of the two clamping jaws 48 and the contact surfaces 60 of the guide rail 12 is illustrated in FIG. 4, which is a horizontal section according to FIG. 3.

In order to release the positive locking of the two clamping jaws 48 with the guide rail 12 and thus to release the clamping device 18, a push button 40 of an unlocking unit 30 shown in FIGS. 7 and 8 must be actuated by hand. This is done in such a way that the unlocking unit 30 in the direction of the

Underframe 10 moves and the cable 50 is moved in the direction of arrow (arrow 51) (Figure 3). The cable 50 is fastened to the guide pin 46, which is connected to the fixing element 52. As a result of the movement of the cable 50 in the direction of arrow 51, the fixing element 52 is moved upward in the direction of arrow 53 (FIG. 5). In this case, the contact of the fixing element 52 with the two clamping jaws 48 is released, so that these are brought out of engagement with the guide rail 12 inwards by a slight pivoting movement (arrows 55 in FIG. 5). FIG. 6 shows the arrangement of the two clamping jaws 48 in a horizontal section according to FIG. 5.

in Figures 7 and 8, the unlocking unit 30 is in each case in two different

Shown views, wherein Figure 7 shows this in a side view and Figure 8 shows this in a plan view. The unlocking unit 30 essentially consists of a carrier part 32 with fastening parts 34 for the cable pulls 50 and a push button 40. The cable pulls 50 are each fastened in pairs to the carrier part 32. Each of the cables 50 runs over a cable pulley 54 which is rotatably mounted on the base 10 of the assembly. In the starting position of the unlocking unit 30, the clamping device 18 is in its locking position, in which the clamping jaws 48 of the clamping device 18 are positively connected to the guide rail 12. If the clamping device 18 is to be released so that the structural unit can be moved within the guide rails 12 or removed therefrom, then - as has already been explained above - from

Hand press the push button 40. The entire unlocking unit 30 is moved in the direction of arrow 41 and the cables 50 are pressed further around the cable pulleys 54. This results in a displacement movement of the cable pulls 50 in the direction of arrow 51, which has the consequence that the fixing element 52 (FIG. 3), which is arranged at the other end of the cable pulls 50 and connected to them, is moved upward against the force of the compression spring 44 (arrow 53). The locking position of the clamping device 18 is thus released. 5 The assembly can now be freely moved within the guide rails 12 or removed from them. The invention enables in particular a smooth movement of the assembly over the rollers 14. On the other hand, the invention advantageously makes it possible to remove the assembly from the guide rails 12 at any point and to reinsert it. This considerably simplifies the I 0 assembly and disassembly of the structural units.

To lock the assembly within the guide rails 12, the pushbutton 40 of the unlocking unit 30 must be released so that no force acts on it. Here, the fixing element 52 of the clamping device 18 is moved downward ⁵ by the force of the compression spring 44 and the clamping jaws 48 are thereby pressed outwards against the guide rails 12. Due to the positive connection between the clamping devices 18 and the guide rails 12, the structural unit is locked in its position again.

When the fixing element 52 is moved downward, the cables 50 20 are simultaneously moved in the opposite direction to the arrow 51. As a result, that too

Unlocking unit 30 inevitably moves in the opposite direction of arrow 41 shown in FIG. To limit the displacement movement of the unlocking unit 30, a stop 36 is arranged on the underframe 10 of the structural unit.

FIG. 9 shows a schematic representation of a segment of a floor 20 with two guide rails 12 arranged therein parallel and spaced apart from one another. The guide rails 12 are embedded in the floor 20. The connection of the guide rails 12 to the floor 20 can advantageously be made by screw or adhesive connections.

50

FIG. 10 shows a section across a guide rail 12 according to FIG. 9. The guide rail 12 is integrally connected to the floor 20 by an adhesive 56. The guide rail 12 has a symmetrical profile, with the conductor tracks 26 in its upper region, within prism guides 16 formed on both sides

55 are arranged. Below the prism guides 16 are the contact surfaces 60 of the guide rail 12, which have a wavy contour - as already explained with reference to FIG. 4. The undulating contour of the contact surfaces 60 of the guide rail 12 can be seen in the illustration according to FIG. 11, which shows a plan view of a partial section of a guide rail 12. FIG. 12 shows a second exemplary embodiment of a guide rail 12 of the device according to the invention. Here, another example of a multifunctional guide rail 12 is shown, which can preferably be used to hold a table. The double-track guide rail 12 is integrally connected to the floor 20 by an adhesive 56. The guide rail 12 has a combined T and L profile, conductor tracks 26 advantageously being integrated in both profiles. It is also possible to design the guide rails 12 both double and multi-lane with the same or different profile geometry.

The adjustment and locking of a component received by the guide rails 12, for example a table in a motor home, is carried out in the manner already described. The multifunctionality due to the advantageous design of the guide rails 12 with regard to the possibilities of an electric drive, the power supply, the communication and the data transmission is also given in this embodiment of the invention. The invention provides the framework for geometrically designing the profile of the guide rails 12 differently without having to do without the multifunctional use of the guide rails 12. A reversal of the L and T profiles of the guide rails 12 in the form of outer profiles already shown is possible.

FIG. 13 shows a second exemplary embodiment of a clamping device 18 of the device according to the invention. The guide rail 12 has a profile with an L-groove. Instead of a double-acting clamping device 18, in which within a guide rail 12 with the profile of a T-groove two clamping jaws 48 for producing a

Form-fit are arranged, only one jaw 48 is arranged here. The functioning of this clamping device 18 is analogous to the functioning of the clamping device 18 already described above. The difference essentially lies in the fact that a form fit with the guide rail 12 can only be produced here via a clamping jaw 48. Since the construction of this clamping device 18 is simpler and fewer components are required for this, this design of the clamping device 18 offers itself as a less expensive variant solution.

FIG. 14 shows a third exemplary embodiment of a clamping device 18 of the device according to the invention. The guide rail 12 here also has a profile with an L-groove, the undulating contour being formed on an obliquely running contact surface 60 of the guide rail 12. The clamping jaw 48 has a contour of its contact surface 62 which corresponds to the contact surface 60 of the guide rail 12. Instead of a double-acting clamping device 18 is here likewise only one clamping jaw 48 is arranged. The difference from the exemplary embodiment described above also lies in the shape of the fixing element 52. As the illustration shows, the fixing element 52 is advantageously of wedge-shaped cross section. This training ensures that the production of a

Connection of the clamping jaw 48 to the guide rail 12 is generated by the fixing element 52, a force component with which the clamping jaw 48 is pressed against the guide rail 12. This advantageously creates a positive and non-positive connection between the clamping jaw 48 and the guide rail 12. In this embodiment of the invention, the geometric design of the

Fixing element 52 achieved a particularly stable and absolutely play-free position fixation of the assembly in the directions x, y and z of the means of transport.

FIG. 15 shows a fourth exemplary embodiment of a clamping device 18 of the device according to the invention. The guide rail 12 has a profile with a

Groove, the undulating contour being formed on a perpendicular contact surface 60 of the guide rail 12. The clamping jaw 48 has a contour of its contact surface 62 which corresponds to the contact surface 60 of the guide rail 12. The main difference from the exemplary embodiment described above is that the fixing element 52 also has a wavy contour

Has contact surface that corresponds to the contour of the contact surface 60 of the guide rail 12. The fixing element 52 is acted upon in the vertical direction by the force of a compression spring 44. Before the clamping jaw 48 is inserted into the guide rail 12 in the clamping device 18, the fixing element 52 is arranged in such a way that its undulating contour is offset by half a pitch relative to the contour of the clamping jaw 48. When the clamping jaw 48 is inserted into the guide rail 12, the fixing element 52 in the clamping device 18 is pressed upward against the force of the compression spring 44 due to the offset of the wavy contour. After the clamping jaw 48 has assumed its end position and is locked in place with the guide rail 12, the fixing element 52 can also be moved with the guide rail by slightly shifting the structural unit

12 snap into place. This advantageously creates a positive and non-positive connection between the clamping jaw 48, the guide rail 12 and the fixing element 52. The particular advantage of this exemplary embodiment of the invention is that the geometrical design of the fixing element 52 also makes it particularly stable and absolutely free of play in the directions x, y and z of the means of transport

Fixing the position of the unit is achieved. Figures 16 and 17 show a fifth embodiment of a clamping device 18 of the device according to the invention in different sectional views. The guide rail 12 here has a profile with an L-groove, the wavy contour of the contact surface 60 being formed on the wrap-around surface of the guide rail 12. In this exemplary embodiment, the fixing element 52 provided in the other exemplary embodiments of the clamping device 18 is omitted. The clamping jaw 48 likewise has a contact surface 62. The force of a compression spring 44 acts on the clamping jaw 48 via a lever 64 and is movable in the vertical direction. The lever 64 is connected to a camshaft 68, which has an eccentric cam 66. The eccentric cam 66 is in contact with the clamping jaw 48 within a correspondingly designed recess. The clamping device 18 is locked and released in each case by rotating the camshaft 68 via the lever 64 by a certain angle.

In the locking position of the clamping device 18, the clamping jaw 48 is automatically held by the force of the compression spring 44, which presses the lever 64 downward. In this case, the clamping jaw 48 with its contact surface 62 is pressed firmly against the contact surface 60 of the guide rail 12 via the eccentric cam 66. The wavy contours of the contact surface 60 of the guide rail 12 and the contact surface 62 of the clamping jaw 48 create a positive connection between the two parts 12, 48 due to their interlocking. In this advantageous manner, a particularly stable and absolutely play-free position fixation of the structural unit is achieved in the directions x, y and z of the means of transport.

If the locking of the clamping device 18 is to be released, the lever 64 is against the actuating unit 30, which is connected to the cable pull 50

Force the compression spring 44 to move upward. This is done by the in the recess

Eccentric cam 66 arranged on the clamping jaw 48 moves the clamping jaw 48 downwards. A pin 70 is attached to the camshaft 68 by the force of a compression spring

72 is brought into contact with an inclined sliding surface 74 of a groove machined into the clamping jaw 48. When the camshaft 68 is rotated, the pin 70 slides along the inclined sliding surface 74 of the clamping jaw 48 and thereby moves the clamping jaw 48 out of the contact area with the guide rail 12 against the force of the compression spring 72.

By turning the camshaft 68, the

Connection of the clamping jaw 48 dissolved with the guide rail 12 and the jaw 48 brought into a position within the guide rail 12, in which the ^'assembly freely moved within the guide rails 12 or can be removed therefrom. FIG. 18 shows one possibility for the mechanical processing of a guide rail 12 in accordance with the configuration in FIG. 14. The guide rails 12 can be produced inexpensively, for example, from aluminum in the extrusion process. The wavy contour of the contact surface 60 of the guide rails 12 can advantageously be achieved by mechanical processing of the guide rails 12 produced by the extrusion process. For example, it is also possible to produce a separate part with a wavy contour made of the same or a different material, which is then joined, for example glued, to the guide rail 12.

Mechanical processing is particularly concerned with generating a wavy contour on the inclined surface of the guide rail 12, which is to serve as the contact surface 60, with little technological effort and to keep the production costs as low as possible. According to the illustration in FIG. 15, it is provided that the wavy contour of the contact surface 60 is produced by punching in the desired shape and in the desired length. The machining tool 58 shown, which has a shape adapted to the wavy contour to be produced, is moved in the direction of the arrow, that is to say obliquely from top to bottom, along the contact surface 60 of the guide rail 12 to be machined and material is removed from the contact surface.
