Description

The present invention relates to a support structure for a vehicle seat of a vehicle, a vehicle seat for a vehicle as such and a vehicle and in particular a motor vehicle.

Vehicle seats are generally used in vehicles to accommodate people. Vehicle seats of this type are often equipped with a support structure for adapting the legroom and the like, which enables a lateral displacement of the seat body. In addition, however, it is often desirable to allow the vehicle seat to be rotated about an axis of rotation that is vertical with respect to the vehicle in order to adapt the vehicle seat to a more comfortable sitting position or to assist in getting in and out. For this purpose, a large number of additional seat components have been devised which allow such a rotation independently of the lateral movement of the vehicle seat and which are frequently constructed from a large number of additional components and cannot be used, for example, with standard seats.

The invention is based on the object of providing a support structure for a vehicle seat, a vehicle seat of a vehicle and a vehicle as such, in which the rotation of a vehicle seat about a vertical axis of rotation relative to the vehicle is possible with comparatively simple means and also in connection with conventional vehicle seats is feasible, for example in connection with a retrofit kit.

The object on which the invention is based is achieved according to the invention with a support structure for a vehicle seat of a vehicle with the features of independent claim 1, with a vehicle seat according to the invention with the features of claim 10 and with a vehicle according to the invention with the features of claim 11. Advantageous further developments are the subject of the respective dependent claims.

According to a first aspect of the present invention, there is provided a support structure for a vehicle seat of a vehicle, in which at least one pair of upper rails can be mounted on a seat body of the vehicle seat in a common mounting plane and extends parallel to the mounting plane. At least one pair of bottom rails that can be mounted directly or indirectly on a vehicle floor of the vehicle is formed. The top rails and the bottom rails are assigned to one another in pairs and can be held within and / or against one another by engagement via a coupling element. A respective top rail and a respectively assigned bottom rail can be displaced in and / or against one another and relative to one another via a respective coupling element along an at least local rail direction. A respective upper rail and a respective lower rail have a toothed section. A coupling element is formed between an upper rail and an associated lower rail. The coupling element is designed to mesh with the toothed sections and to be set in a combing movement and in particular in rotation during the combing, whereby the coupling causes a combing movement on the side of an upper rail or a lower rail to a combing movement on the side of an associated lower rail or upper rail leads. When the coupling element engages and intermeshes in the toothing sections of an upper rail and a lower rail at the same time, the upper rail can be pivoted about a pivot point parallel to the mounting plane and is set up for screwing in the vehicle seat relative to a vehicle floor parallel to the mounting plane. Advantageously, according to the present invention, a vehicle seat can be screwed in or pivoted out of the structure of the support structure alone, without the need for additional complex devices or mechanisms.

The top rails and / or the bottom rails can be designed linearly or in sections linearly and / or in each case each other or altogether identically to one another or overall. In an assembled state, the top rails and / or the bottom rails can be designed or arranged with one another or with sections overall running parallel to one another or overall running parallel to one another.

In an advantageous development of the support structure according to the invention, the coupling element is set up to be displaceable in a top rail and / or in a bottom rail outside of a respective toothing area in the top rail or bottom rail in order to enable translation of the vehicle seat relative to the vehicle floor parallel to the mounting plane or to effect.

In another development of the support structure according to the invention, a respective upper rail and / or a respective lower rail can be formed sectionally or completely with a toothing region along a running surface.

In particular, it is advantageous if the respective upper rail is formed completely with a toothing area, in particular on the running surface of the rail, because precisely then any intervention in a toothing area in the lower rail leads to pivoting the top rails and thus the assembled vehicle seat.

Different structures are conceivable for the construction of a respective coupling element.

• - eingerichtet ist, mit einer zugeordneten Oberschiene und einer zugeordneten Unterschiene einzugreifen ,
• - ein erstes kämmendes Element aufweist, welches zum Eingreifen mit der zugeordneten Oberschiene und beim Eingreifen mit einem Verzahnungsbereich der zugeordneten Oberschiene zum Kämmen mit dem Verzahnungsbereich eingerichtet ist,
• - ein zweites kämmendes Element aufweist, welches zum Eingreifen mit der zugeordneten Unterschiene und beim Eingreifen mit einem Verzahnungsbereich der zugeordneten Unterschiene zum Kämmen mit dem Verzahnungsbereich eingerichtet ist, und
• - ein Übertragungselement aufweist, welches eingerichtet ist, eine Kämmbewegung eines der kämmenden Elemente des Koppelelements in eine Kämmbewegung des anderen kämmenden Elements des Koppelelements zu übertragen, insbesondere durch getriebemäßige Kopplung.

However, it is particularly advantageous if a respective coupling element

• is set up to intervene with an assigned upper rail and an associated lower rail,
• has a first intermeshing element which is designed to engage with the associated top rail and, when engaging with a toothing region of the associated top rail, to mesh with the toothing region,
• has a second meshing element which is designed to engage with the associated bottom rail and, when engaging with a toothing region of the assigned bottom rail, to mesh with the toothing region, and
• has a transmission element which is set up to transmit a meshing movement of one of the meshing elements of the coupling element into a meshing movement of the other meshing element of the coupling element, in particular by means of a gear coupling.

• - ein jeweiliges kämmendes Element ein Zahnrad ist oder aufweist, wobei die kämmenden Elemente eines Koppelelements identisch oder zum Erzielen einer Übersetzung mit unterschiedlicher Größe ausgebildet sind und/oder
• - das Übertragungselement eines jeweiligen Koppelelements eine Getriebeanordnung und/oder eine die kämmenden Elemente direkt koppelnde Welle ist oder aufweist.

In this case, it is also conceivable that

• - A respective meshing element is or has a gearwheel, the meshing elements of a coupling element being identical or designed to achieve a translation with different sizes and / or
• - The transmission element of a respective coupling element is or has a gear arrangement and / or a shaft coupling the meshing elements directly.

• - zu dieser mittelbaren Montage einer jeweiligen Unterschiene an den einen Fahrzeugboden des Fahrzeugs für jede Unterschiene eine unmittelbar an den Fahrzeugboden des Fahrzeugs montierbare Basisschiene ausgebildet ist,
• - die einander paarweise zugeordneten Unterschienen und Basisschienen durch direktes Eingreifen miteinander in- und/oder aneinander halterbar sind und
• - eine jeweilige Unterschiene und eine jeweils zugeordnete Basisschiene entlang einer zumindest lokalen Erstreckungsrichtung der Schienen in- und/oder aneinander und relativ zueinander verschiebbar sind, um eine Translationsbewegung eines Fahrzeugsitzes zu ermöglichen.

The translational movement of a vehicle seat to be assembled can be realized particularly advantageously if, according to another advantageous embodiment of the support structure according to the invention, an indirect assembly of the lower rails is selected, wherein

• a base rail which can be mounted directly on the vehicle floor of the vehicle is formed for this indirect mounting of a respective lower rail on the one vehicle floor of the vehicle,
• - The bottom rails and base rails assigned to one another in pairs can be held in and / or against one another by direct engagement with one another and
• a respective lower rail and a respectively assigned base rail can be displaced in and / or against one another and relative to one another along an at least local extension direction of the rails in order to enable a translational movement of a vehicle seat.

The top rails can in principle be designed for direct mounting on a vehicle seat and in particular on the underside or bottom surface of a corresponding seat body, so that an attachment to the vehicle seat and thus the mounting of the vehicle seat in the vehicle can take place without additional intermediate elements to be mounted.

However, according to another advantageous embodiment of the support structure according to the invention, it is possible to design it with a central support arrangement with at least one central support, via which the top rails can be mounted indirectly on the seat body of the vehicle seat.

The center beam thus acts as an intermediate element between the top rails and the seat body and can therefore be designed in such a way that, due to the asymmetrical tensioning of the top rails, forces arising in relation to one another can be better absorbed and buffered, so that direct mounting means such as mounting holes and screws are subject to less mechanical stress subject.

In this case, the top rails can be rotatably mounted on the central support arrangement and / or on the central support.

This can be done in particular via rotatably mounted or rotatably mounted mounting points.

It is particularly advantageous if, according to another exemplary embodiment of the support structure according to the invention, the central support arrangement and / or the central support are arranged in a main direction of extension essentially transversely to the direction of extension of the top rails and in particular have a variable length in the main direction of extension due to elasticity and / or telescopability is adaptable to each other depending on the position of the top rails. In this way, a particularly high degree of adaptability of the support structure to the force relationships acting during assembly is established.

For this purpose, according to another advantageous exemplary embodiment of the present invention, the top rails can be rotatably mounted on the central support. especially via pivoted or pivoted mounting points.

As an alternative or in addition, it can be provided that the center carrier arrangement is formed not only from a center carrier, understood as a general coupling between the carrier structure and the seat body, but from a plurality of carrier elements which interact in the manner of a cranesbill, a parallelogram structure or a double scissor structure.

Furthermore, the central support can additionally or alternatively extend in a main direction of extension essentially transversely to an - at least local - direction of extension of the top rails and, in the main direction of extension due to elasticity and / or telescopability, have a variable length that can be adapted to one another depending on the position of the top rails , By means of these measures, the mechanical load on the mounting points of the top rails on the central support on the one hand and of the central support on the seat body on the other hand can be reduced particularly effectively.

The present invention also relates to a vehicle seat for a vehicle as such. The proposed vehicle seat has a seat body and a support structure designed according to the invention. Upper rails of the support structure are attached to the seat body for mounting the support structure on the seat body.

Furthermore, the present invention also provides a vehicle as such, which can be designed in particular as a motor vehicle, as a passenger car, as a bus and the like. However, it is also conceivable to use it in other means of transport in which people have to be placed, for example in airplanes, ships or sections of trains or general means of local transport.

The respective vehicle has a body, which surrounds an interior of the vehicle, and is formed with a vehicle floor. Furthermore, a vehicle seat designed according to the invention is part of the vehicle, which is attached to the vehicle floor of the vehicle via lower rails of an underlying support structure.

At the bottom of the seat part 21-1 is the base 21-0 attached that also as a base or substructure can be designated. At the bottom of the base 21-0 is a top of the top rails 11 appropriate. The top rails 11 are bottom rails 12 assigned with which they are engaged in the assembled state and a displacement movement in the main direction of extension 13 that for all top rails 11 and bottom rails 12 is identical in the non-pivoted state, allow the main direction of extension 13 the top rails 11 and bottom rails 12 in the non-pivoted state parallel to the longitudinal direction of the vehicle X is aligned.

The supporting structure is accordingly 10 according to the present invention in the in the 1A and 1B shown embodiment of the top rails 11 and the bottom rails 12 formed in engagement with each other.

The running surface of the lower rail 12 on the other hand is only in one section with a toothing area 12-1 formed, namely in a portion which is spaced from the front of the vehicle.

2 shows a schematic and partially sectioned top view of an embodiment of the support structure according to the invention 10 for the immediate installation of lower rails 12 on a vehicle floor 2 ,

In the 2 illustrated embodiment of the support structure according to the invention 10 is essentially formed by a pair of identical bottom rails 12 which can be mounted on the vehicle floor of a vehicle. The two lower rails 12 can be mounted at a distance from each other and run parallel to each other in the direction of extension 13 , Furthermore, the bottom rails 12 in the representation according to 2 mounted on butt.

Any bottom rail 12 is a circular curved top rail 11 assigned. A coupling from the top rail 11 and bottom rail 12 takes place via a coupling element provided in each case 15 , which can also be called a coupling link.

Also the two top rails 12 are identical to each other and are in the in 2 arrangement shown in sections and / or locally aligned parallel to each other.

A respective bottom rail 12 has a toothed section 12-1 on which is terminally trained. The gear sections 12-1 of the two lower rails 12 are identical to each other.

The top rails 12 each have identical toothing sections 12-1 which in relation to the extension of the top rails 11 are arranged approximately centrally.

The coupling elements 15 are formed by a first and a top rail 11 associated combing element 15-1 , which can also be referred to as a first engagement element, of a second and a lower rail 11 associated combing element 15-2 , which can be called a second engagement element, and a transmission element 15-3 , which can be designed as a shaft or gear, in particular about an axis of rotation 15-4 of the coupling element 15 define. The coupling element 15 can be designed as a one-piece component.

At the in 2 The embodiment shown is the respective second meshing element 15-2 each set up in the assigned bottom rail 12 along the direction of extension 13 to be linearly displaceable or displaceable, as long as there is no engagement of the toothing of the second engagement element 15-2 with the gearing 12-1 the bottom rail 12 he follows.

When the teeth of the second gear mesh 15-2 with the gear area 12-1 the respective bottom rail 12 there is a rotation of the coupling element 15 about the corresponding axis of rotation 15-4 , whereby the first meshing element coupled thereto 15-1 is also set in rotation. By rotating the first meshing element 15-1 of the coupling element 15 takes place by engaging the teeth of the first meshing element 15-1 with the gearing 11-1 the top rail 11 a twisting 55 or pivoting the top rail by a certain pivot angle 56 ,

At the in 2 illustrated embodiment are at terminal mounting points 31 , which are rotatably mounted or are rotatably mounted, first and second carrier parts 30 - 1 respectively. 30 - 2 a center beam arrangement 30 ' as a central girder 30 for a vehicle seat 20 educated.

3 shows a schematic and partially sectioned top view of an embodiment of the support structure according to the invention 10 for indirect mounting of provided lower rails 12 on a vehicle floor 2 , namely with the interposition of base rails 18 for direct mounting on the vehicle floor 2 ,

At the in 3 illustrated embodiment of the support structure according to the invention 10 is in addition to the in 2 components shown still a pair of identical and butt-mountable base rails 18 trained in which the lower rails 12 are assigned and with which the lower rails 12 intervene and so an only indirect assembly - for example in 1A and 1B shown embodiment - on the vehicle floor 2 of an underlying vehicle 1 cause.

In the 3 The arrangement shown enables the lower rails to be moved in translation 12 in or on the base rails 18 to a linear adjustment of the on the center support assembly 30 ' mounted vehicle seat 20 to effect.

These and other features and characteristics of the present invention are further illustrated by the following statements:

Most vehicle seats have a translational adjustment option in the direction of travel. Seat depth adjustment and translations up and to the side are also known. Possibility to rotate the seat like this in 1 shown, has so far only been realized in a few versions, for example in motorhome seats, child seats, and large vehicles.

What these seats have in common is that the rotation is realized in a separate assembly in the seat frame, in contrast to the seat rail and the screw connection.

The translational displacement in currently used seats in motor vehicles is usually carried out via a system with a lower rail attached to the vehicle floor and an upper rail mounted therein. The top rail is in turn firmly connected to the seat or seat body.

So far, special seating structures have to be developed and produced for the function of the occupant rotation. Additionally or alternatively, increased installation space, costs and weight have to be accepted if, for example, appropriate adapters are added to effect a rotation. This is in contrast to the use of identical parts of established seat structures or the adaptation of corresponding translational seat rails.

There is currently no function-integrative solution for screwing in and translating vehicle seats. These are solved with separate components and / or assemblies.

The idea of the invention is to turn an occupant into a special rail system with top rails 11 and bottom rails 12 to enable. These are two rails lying side by side or one above the other 11 . 12 , It is a respective bottom rail 12 extends straight or linear and the other and associated top rail 11 is curved, for example circular.

In between there is a coupling and / or a brake in the sense of a coupling element 15 , which with their abrasion, in particular thus via intermeshing elements 15-1 . 15-2 and for example via gears on both rails 11 . 12 ends.

In one version the curved top rail has 11 a tooth engagement over a defined length, which also serves as a toothing section 11 Is called -1. The linear or straight bottom rail 12 only has a toothed section in a partial area, for example at the end 12 -1 on. If the seat 20 is pushed back and forth, for example along the direction of the arrow 50 , grabs the gear 12 - 1 initially not on the straight or linear bottom rail and there is a purely translational shift.

Now get the seat 20 by moving it to an area of the bottom rail 12 , in which the straight bottom rail also meshes 12-1 has, the coupling rod 15-3 of the coupling element 15 driven to rotate and thus the curved top rail 11 about the engagement of the meshing element 15-1 with the gear section 11-1 pivoted.

This results in a total rotation of the support structure 10 mounted seat 20 ,

In another version, the straight lower rail has 12 A toothing over the entire adjustment range 12-1 , Here, the occupant can use a clutch - for example on the coupling element 15 - decide whether the straight bottom rail 12 and curved top rail 11 get connected. In each position of the longitudinal adjustment of the seat, a decision can be made as to whether rotation should be initiated with a further longitudinal adjustment of the seat.

The vehicle seat 20 is with the curved top rail 11 coupled.
