Description

The present invention relates to a device for Anchoring a seat to a vehicle floor with the mark paint the preamble of claim 1; further concerns the present invention a use of such Contraption.

The so-called airline rail is all from the prior art commonly known, a rail for fastening seats, Lashing or holding devices in vehicles various of a kind with a lengthways - typically in motion direction - extending, undercut groove and one Provide multiple for anchorage in the groove NEN, usually arranged at regular intervals Breakthroughs.

Not only in aircraft, but also increasingly in the car and The truck sector finds this flexible type of seat and drawer Well fastening increasingly application because of the genus moderately known manner flexible, with little assembly effort and easy to change loading and pas can be designed variably.

So seats or the like on a generic airline Devices typically to be attached to the rail connected to a sled that slides in the rear cut groove of the airline rail and included Means is provided, the sled - and therefore the on attached seat - at a predetermined position in to anchor the rail.

However, such a known device some drawbacks, which are particularly practical Operation and with greater load on the airline rail than prove to be in need of improvement  turns of the airline rail in a longer vehicle cabin the problem of torsion, namely twisting of the Floor (and thus also the airline Rail) due to body rubbers that occur during the journey movements. Such twists (or others, on the drive static or dynamic forces acting on the floor of the then to a corresponding influencing of the Rail groove certain path, with the effect that a traditionally one-piece sled, in the groove is slidably received, jammed, tilted or open limited other ways in its adjustment options is.

Furthermore, the traditional attachment of seats, for example on such a sled (which is then used to fix the Sitting position by engaging in one of the openings of the Rail is fixed) has the disadvantage that, conditionally through the weakest element in the chain: blocking element - Sled - connection of the seat, a maximum force contributes to the mechanical stability of the slide is limited and therefore in practice often a pair of Airline rails only those with the assembly of a single seat associated forces had grown to a plurality of seats (such as a bank or the like) but not on only one Rail (or a pair of rails) could be determined.

In addition, known, for use in an airline Rail provided slides have the disadvantage of being complicated and cumbersome to use, especially the Befe mounting devices.

The object of the present invention is therefore a Generic anchoring device further that not only proper movement of the Sledge also under torsion or other twists of the Vehicle floor (with airline rail sitting in it) possible is, a solution should also be created that in a rail through a structural unit, for example a seat,  force to be introduced with the aim of the existing device also for a plurality in parallel fastening seats or the like. To make suitable without in the event of an impact, the system's load-bearing capacity exceeding maximum force torque is exceeded.

The task is accomplished by the devices with the features of claims 1 and 8 and the use according to the An saying 11 solved; advantageous further developments of the Erfin tion are described in the subclaims.

The slide is made in an advantageous manner according to the invention ten of a plurality (i.e. at least two) can be pivoted articulated slide elements and is thus in the Able to arise from torsion of a vehicle floor changes in the cross section of the undercut in the Adjust airline rail. This will be more advantageous Way avoided that an extreme torsional state of the Vehicle floor leads to jamming of the carriage; rather, the remain even in such operating conditions Sliding in the manner desired by the operator movable.

It has also turned out to be particularly preferred To use plastic as material for a sliding element, that as part of a sled element in the airline rail is arranged movably. Not only does such a part offer simple and inexpensive manufacture and preferred Sliding properties can also be achieved by suitable dimensions sionierung the sliding element a snap connection reali the assembly (or disassembly) in remarkable Way simplified.

Since also, according to a further preferred embodiment of the invention, longitudinal forces (i.e. acting in the direction of travel Forces such as those in the event of an impact or a Braking occur directly through the befe on the seat Stigt retaining element or the associated ratchet  ment will be taken, bypassing the Schlit least when force is applied to the rail, this mecha nisch relieved and can be correspondingly easier or as Plastic part are formed.

The solution of the direct force input from the seat in the Airline rail (without interposing the slide), for which protection is claimed independently according to claim 8 is also achieved in an advantageous manner that the maxi male force entered in this way in the rail can be clearly compared to the prior art can be increased: Now that the sled is the weakest The link in the force input chain is eliminated, the immediate offers bare force input of the seat in the rail, namely by Cooperation of the locking element on the holding element with the Breakthrough the rail, the possibility of a plurality of Sitting or the like. Add-on units with the To connect the rail without the safety-relevant Bela limits are exceeded.

While the present invention is particularly favorable ger way for variable attachment of one or more Suitable seats, however, the present invention is thereon not limited; rather, it lends itself to the present ing invention for others, on airline rails units to be added and anchored with this, for example Containers, cargo securing systems or other units to apply.

It is also particularly preferred according to one embodiment form of the invention, the carriage with a fuse provided him against slipping in the longitudinal direction secures, namely by the locking element according to the invention, which preferably by means of spring force with its profile into the breakthroughs of the Airline rail is pushed in and so for a solid, nevertheless simple - d. H. by pressing down or the like - releasable anchorage. By continuing education  preferred arrangement of the profile engagement in the rail in Direction of travel in front of the locking element joint (whereby this, based on the surface of the airline rail, deeper lies) is also a particularly favorable Self-locking or locking achieved, namely by that by driving force on the sled in motion direction (namely in the event of an impact or the like) an upward-looking and thus the profiling in the Breakthroughs in the airline rail force component arises.

During this embodiment in particular also independently of the above-described solution of the immediate force can be inserted into the rail from the seat a combination is also conceivable; would be in such a case then to provide a unit which, if necessary, for Moving the carriage can release the locking element.

As a result, the present invention is a The proven airline rail has been created in further flexibilize their possible uses and in particular to make it accessible for conditions at what strong torsion and / or twisting of the vehicle floor have caused existing sledges to jam, and / or where the mechanical limits so far Sledges have an upper limit for maximum load traditional airline fastening systems to have.

Fig. 11 shows the longitudinal section through Fig. 9 along the line XI-XI.

A vehicle seat 10 in a vehicle, not shown, according to FIG. 1 consists of a floor-side seat part or seat frame 12 with an approximately horizontally extending seat surface 14 and a - in a joint region 16 connected thereto - folded backrest 18 on the seat surface 14 , one end of which is free Headrest 20 protrudes.

The seat frame 12 of the vehicle seat 10 is detachably connected by two front foot profiles 22 and two rear rear feet 24 to two parallel holding or floor rails 26 , only one of which can be seen in FIG. 1. Both the foot profiles 22 and the rear profiles 24 can each be pivoted to a limited extent about an axle bolt 23 .

The holding or bottom rail 26 is designed as a so-called airline profile and has in its longitudinal axis A an undercut longitudinal groove 28 with an opening width b of, for example, 11 mm and a cross-sectional width e of the undercut area 30 of 20 mm. At a distance from the deepest groove 32 are two side grooves 36 opposite each other on both sides of the longitudinal axis A of the rail in the side walls 34 of the undercut area 30 , from the lower edge of which a horizontal cantilever surface 37 projects. These longitudinal groove 28 is in the range of - provided rail surface 38 with holes 40 whose center lines M at intervals of 25 mm f run - cross through the undercut 30, the groove edges supplying form of ribs formed. The bore diameter d is somewhat shorter than that cross-sectional width e. On the rail surface 38 forming a plane, desk surface strips 39 inclined downward on both sides adjoin it.

In the bottom rail 26 two pairs of cross-sectional Lich L-shaped sliding elements 42 made of plastic with outer side ribs 43 are used. In the upper edges of the sliding elements 42 molded recesses 44 part- circle-shaped contour serve to accommodate cross bolts 46 two seat seats 48 , the components of a element 50 Einsatzele for the bottom rail 26 are. The seat receptacles 48 each consist of two parallel metal strips 51 and brackets 52 connecting their lower edges. Thanks to the choice of material of the sliding elements 42 serving to compensate for tolerances in the bottom rail 26, no rattling noises occur when they are moved; this arrangement also allows simple mounting of seat receptacle 48 and plastic sliding element by snapping or a clip connection.

Each of the sliding elements 42 is articulated by means of a connecting bolt 54 to a connecting body 58 of the insert element 50 , which contains two cranked side strips 56 , the distance i of the connecting bolts 54 measures, for example, 400 mm. Another Ver connecting bolt 54 a is provided outside those seat seats 48 between the side strips 56 .

The insert member shown in Figure 2, multi-part 50 of connector body 48 and each end hinged seat supports. 48 - for connection with the plastic sliding elements 42 - also allows in an advantageous manner the absorption of torsional or -momenten that during assembly of the arrangement in a vehicle floor inevitably occur, particularly in the case of longer lengths; due to the multi-part form according to the invention, the arrangement of the insert element 50 remains movable in the airline rail 26 even in the case of floors loaded by torsional stress or the like and does not lead to undesirable and disadvantageous - as is the case with devices according to the prior art Clamping effects.

The connecting bolt 54 on the left in FIG. 2 engages through the end of a leaf spring 60 which protrudes between the side strips 56 and which is shaped like a transverse sleeve and which can rest on a clamping pin 59 passing below it. The right in Fig. 2 connecting bolt 54 passes through a locking profile 62 from a channel profile with - holes 63 for the connecting bolt 54 offering - side walls 64 , the height h increases towards the articulation end of the locking profile 62 . From the outer surface of the two side walls 64 connecting the channel bottom 65 three INTERLOCKS protrude lung cylinder 66, whose center distance f1 from each other, the distance f of those holes 40 of the bottom rail 26 and the periphery thereof in accordance with the hole contour.

By this arrangement of the locking profile 62 is firstly advantageously achieved that the insert member - at approximately attached in the area of the front foot profile 22 vehicle seat 10 - can be kept in a predetermined longitudinal position in the bottom or airline rail 26, wherein also the constructive realization FIG. 2 by arranging the lock cylinder 66 relative to the hinged end of the lock profile 62 in the direction x to a resulting self-locking effect, so that in particular movements of the assembly along the direction of travel x, as they can for example also be the result of a moment of inertia on impact, the Increase blocking effect. Specifically, this effect is achieved in that - with respect to an engagement of the locking cylinder 66 in the holes 40 of the airline rail 26 - the pivot plane defined by the pair of holes 63 against the direction of travel x and - based on the height of the airline rail 26 - below the locking cylinder 66 is arranged so that a load on the arrangement with an input of force in the direction of travel x is automatically redirected to a force on the locking profile 62 in the upward direction z. As a result, this leads to the desired reinforcement of the blocking effect.

The order described in connection with FIGS. 2 and 3 can now be used directly with a vehicle seat 10 according to FIG. 1 or independently of this. In particular, it is also provided that in the arrangement described in detail in FIGS. 1, 4 to 8, the insert element 50 for the airline rail 26 does not have a spring / locking profile pair 60 , 62 , but rather the locking of the vehicle seat 10 in the manner according to the invention by engaging corresponding, directly on the vehicle seat 10 fastened locking knobs in the holes 40 of the airline rail 26 .

For this purpose, the vehicle seat 10 has a pair of locking knobs 68 on the already mentioned rear foot 24 of the seat part 12 ; these locking knobs 68 are fixed on the underside of a profile element 70 having an inclined outer edge 69 in FIGS . 1, 4, 5. The rear foot 24 also has two further profile elements 72 , 73 , each of which is provided at the free profile end with a receiving opening 76 for one of the transverse bolts 46 of the associated seat receptacle 48 , which is gripped by a pawl 75 which can be pivoted to a limited extent. Also each consisting of a single profile front foot profiles 22 are equipped with bolt receptacles which enclose the cross bolt 46 of the element 50 seat insert 48 in use.

- each formed by a sliding element 42 and an attached seat support 48 - carriage 78 of the insert element 50 is set and locked to this, the vehicle seat 10 6 with its two front base profiles 22 on front is in accordance FIG. the vehicle seat 10 , in the seat frame 12 of which the rear feet 24 are pivoted in, can be moved and positioned on the slide 78 in the longitudinal direction of the rail.

If now the seat frame 12 - as shown in Fig. 7 - the pivot pin 23 of its front base profiles 22 in the direction of arrow y rearwardly rotated, pivoting the rear legs 24 out of the seat frame 12. In FIG. 8, the rear feet 24 then lower into the bottom rails 26 and lock onto the rear slide 78 . The two Riegelnop pen 68 of the rear foot 24 engage in the bottom rail 26 and then prevent displacement of the vehicle seat 10 in the longitudinal direction of the rail.

Advantageously, it is achieved that - in contrast to the known prior art - for the first time an engagement of a locking element in the form of locking knobs 68 in the airline rail 26 for determining the seating position in the direction of travel x takes place immediately, that is, not below interposition of the insert element 50 or of another, in the airline rail guided element 26, fastened to the vehicle seat 10 or hinged components bring about the introduction of force in the airline rail 26 and thus the strength of the joint in the direction of travel x be siderably increased. As shown in FIGS. 1 and 8, the locked position shown in this way - in the event of a collision of the vehicle - directs considerable force directly through the seat arrangement into the floor rail 26 , which opens up completely new design options for the realization of a seat coupling of the present type. In particular, the arrangement shown now makes it possible for the first time to variably and easily move more than one individual seat in the manner described, but nevertheless to fix it firmly in the event of an impact; hitherto the coupling has always been carried out via an insert element in the undercut of the airline rail 26 and thus already provided a design limit for the maximum force input which can be considerably exceeded by the procedure according to the invention.

Together with the further aspect of the invention, namely the multi-part design of the insert element 50 for absorbing torsional moments or the like, this results in a variable seat fastening that is optimized both in terms of its operation and in terms of its mechanical-structural properties For example, it is ideally suited for use in a variable interior of a vehicle that is also intended for seating.

As an alternative embodiment of the invention, the embodiment of the sliding elements 42 illustrated in FIG. 2 and the bottom rails 26 without lateral projecting side ribs 43 or without the side grooves 36 associated with this and described in relation to FIG. 3 is particularly included. Rather, this embodiment provides that the side walls 51 of the insert element 50 are flush with sections of the sliding element 42 , so that a common, continuous and flat side wall is formed which can slide along a correspondingly planar inner side wall 34 a of a floor rail 26 a ; Such a bottom rail 26 a is shown in FIG. 9.

The bottom rail 26 a of FIG. 9 is assigned a insertable slide 80, which can be inserted into its undercut longitudinal groove 28, as a seat receptacle, which contains a U-shaped metal bracket 82 in plan view; the longitudinal legs 84 are connected by two the longitudinal axis B of the slide 80 que rende welding stud 86 . These welding studs 86 are in Fig. 11 near the upper edge 81 of the slide-in 80 most attached to its metal bracket 82 , its cross section is shown here in a circle, but can also be oval or polygonal in shape - optionally also longitudinally cranked.

Near the part-circular curved bracket base 83 of the tall bracket 82 are parallel to those welding studs 86 pa parallel locking pin 88 - each bent out of a longitudinal leg 84 - two mutually at an angle w ver running ribs 90 are provided. Between the Rip penstirn 91 and that bracket base 83 , a plunger 93 can be inserted from a block-like, rounded base body 94 and two upstanding thereof - connected by means of an integrally formed intermediate web 95 - slice sections 96 inserted. The center distance n corresponds to the distance f of the bore center lines M of the bottom rail 26 _a , the circumference of the disc sections 96 is matched to the shape of the bore contour of the bottom rail 26 _a .

In the bottom of the base body 94 , a receiving groove 97 is formed in the center for the spring pin 80 mentioned. The plunger 93 passes through in the cross-sectional axis Q of the receiving groove 97, a grub screw 100 . In a lower position of the plunger 93 , the groove base 98 of the receiving groove 97 rests on the dowel pin 88 , and the disk sections 96 run inside the longitudinal leg 84 , ie below the upper edge 81 of the insertion slide 80 . If the set screw 100 runs onto the dowel pin 88 in the described screwing operation, the plunger 93 is raised, and in the process those disk sections 96 are pressed into the bores 40 of their bottom rail 26 _a . If the slide-in slide 80 is clamped in this position, it is fixed against rattling. The seat adjustment is possible without a lever on the vehicle seat 10 .
