Description

The invention relates to a rail arrangement for a vehicle seat, a seat arrangement for a vehicle, and a vehicle.

Rail arrangements are known as part of a vehicle seat, which can conventionally ensure a longitudinal displacement of the vehicle seat. For this purpose, a seat rail consisting of two rail elements is provided, which lie slidably on top of one another and which can move in a lateral direction towards one another. One of the rail elements is connected to the vehicle seat, for example a seat part of the vehicle seat, via a seat part carrier, via which the longitudinal displacement can be ensured.

Often the seat track of the track assembly is hidden beneath a recessed floor located above the chassis of the vehicle, leaving a slot in the floor through which the seat bottom support protrudes. Objects and dirt can get through this slot in the floor, which can impair the function of the seat rail (longitudinal displacement).

To avoid this, in FR 2 848 926 A1 suggested covering the seat track and slot in the floor with masking tape. The masking tape runs from one end to the other end of the slot and is fixed to the chassis or floor. When the vehicle seat is longitudinally displaced, a guide plane of the seat part carrier slides on a lower surface of the cover strip. The cover strip is held on the guide level by two pins above the guide level.

Another variant of covering the slot in the floor is in DE 10 2019 135 747 A1 described. It is proposed therein to use a cover strip which is fastened with its end areas to the seat part carrier. Guide brackets running in the lateral direction are arranged in the floor above the seat rails. In these, the cover strip is guided in a longitudinally displaceable manner, for example via grooves or openings, in which the cover strip is accommodated on both sides in such a way that the movement of the cover strip in the vertical and horizontal directions is restricted. For deflection, deflection systems or deflection units in the form of rollers are provided in deflection areas on both sides of the guide mount, the axes of rotation of which are aligned in the horizontal direction. As a result, the tape is guided back underneath the seat rail from one end of the guide bracket to the other end, so that when the vehicle seat moves, the cover tape can move with it and the slot is permanently covered.

The disadvantage of this solution is that space for the return of the cover strip has to be planned underneath the seat rail, which is very expensive. In addition, design-related disadvantages can arise in the rigidity of the seat rail, since the surrounding elements, which also hold the seat rail, also have to be aligned for a return of the cover strip.

The object of the invention is therefore to create a rail arrangement and a seat arrangement for a vehicle seat in a vehicle that are designed to be space-saving and simple as well as robust.

This object is achieved by a rail arrangement, a seat arrangement and a vehicle according to the independent claims. The dependent claims indicate preferred developments.

According to the invention, a rail arrangement for a vehicle seat is therefore provided with a seat rail, a guide bracket running in the lateral direction and at least one (flexible, elastic) cover strip, which can be connected to the vehicle seat indirectly via a further element, e.g. a seat part carrier, or directly , wherein the at least one cover strip is guided by the guide mount in such a way that a movement of the at least one cover strip is permitted at least in the region of the guide mount in the lateral direction and restricted in a vertical direction and in a horizontal direction. The cover strip can therefore move in the lateral direction together with the vehicle seat and therefore follows it.

The guide bracket is arranged above (in the vertical direction) the seat rail in such a way that the at least one cover strip guided in the guide bracket covers or conceals the seat rail at least in regions at the top, with the band plane of the at least one cover strip in the region of the guide bracket preferably being in oriented in the horizontal direction. When installed in the vehicle, the cover strip can therefore be arranged above the seat rail in the area of a slot in a floor and ensure that no dirt or objects get to the seat rail.

The at least one cover strip also runs outside the guide mount in a first deflection area around a first deflection unit and in a second deflection area around a second one Deflection unit, which deflect the at least one cover strip in each case, ie change its direction, with the two deflection areas being located on opposite sides of the guide bracket in the lateral direction. The cover strip is thus specifically deflected in the lateral direction above and below the guide mount, ie when the cover strip is no longer guided in the guide mount.

According to the invention, it is provided that the two deflection units are arranged and designed in such a way that a belt plane of the at least one cover belt, i.e. the plane or surface in which the cover belt moves, is vertically aligned in the first and in the second deflection area at least after the deflection is. The masking tape is thus deflected sideways (in the horizontal plane X-Y) and not vertically downwards. This already has the advantage that no more space is required below the seat rail. As a result, the chassis-fixed substructure to which the seat rail is attached can be designed so that optimum rigidity of the seat rail is achieved and maintained. The course of the cover strip above this base does not affect this construction, so that a simple and very robust rail arrangement can be created.

It is preferably also provided that the two deflection units are each designed as rollers and the axes of rotation of the two rollers are aligned in the vertical direction, with the at least one cover strip running around the rollers, so that the belt plane of the at least one cover strip in the first and in the second Deflection area is aligned at least after deflection in the vertical direction. In this way, a simple deflection can take place with a simultaneous change in the orientation of the belt plane, whereby the movement of the cover belt can be supported by the rotating rollers. In principle, however, a non-rotating and smoothed shaft with the direction of expansion in the vertical direction can also be used in the same way, on which the cover strip runs for deflection with little sliding friction.

According to one embodiment, a single cover strip is provided, which can also be composed of two or more sub-strips, and the two rollers are designed as deflection rollers, each with a vertically aligned axis of rotation, with the two deflection rollers on the opposite sides of the guide bracket are arranged, with the single cover strip on the respective side of the guide bracket being deflected by the deflection rollers around the respective axis of rotation and the single cover strip running between the two deflection rollers adjacent to the guide bracket, i.e. outside the guide bracket, in a return area (additionally or parallel to the guided arrangement of the cover strip within the guide bracket).

In this embodiment, the cover strip is returned without requiring space below the seat rail, since the strip level is previously aligned in the vertical direction via the deflection rollers. A small distance from the seat rail can therefore be selected for the adjacent return, which saves space. In this case, it can preferably be provided that the return region, seen in the horizontal direction, lies next to or horizontally to the side of the seat rail. Since there are normally no other elements to the side of the seat rail, the return area can be selected close to the seat rail, resulting in a small lateral expansion of the arrangement.

It is preferably additionally provided that the belt plane of the single cover belt is aligned in the vertical direction between the two deflection rollers in the return area. There is therefore no further deflection and/or change in the alignment of the cover strip, as a result of which the cover strip can easily be fed back on edge and thus in a space-saving manner next to the seat rail.

It is preferably also provided that two separate cover strips are provided and the two rolls are designed as winding rolls, each with a vertically aligned axis of rotation and a vertically aligned shaft, with each cover strip being assigned to a different winding roll and the respective cover strip being wrapped around the respective one by the respectively assigned winding roll Axis of rotation is deflected and the respective cover strip can be wound up or unwound in a vertical direction on the shaft of the respective winding roll with a rotation of the winding roll with the tape level. Therefore, as an alternative, instead of being returned, two separate cover strips can also be wound up or unwound if the cover strips move in a lateral direction when the vehicle seat is displaced within the guide bracket, with the part then protruding from the guide bracket being wound up on the winding rollers in a vertical orientation can be. Space can also be saved as a result, since in this case space is not required for the cover strip either below or on the side of the seat rail.

Provision is preferably also made for at least one of the rollers to be spring-loaded in a defined direction of rotation. This allows in at be achieved that the respective cover tape is kept taut or in the embodiment with the winding rollers can be wound up with a movement in the corresponding lateral direction.

Provision is preferably also made for the at least one cover strip to be in the form of a steel strip or a textile strip or belt, preferably made of natural fibers or man-made fibers, with the textile strip preferably being reinforced with steel cords. This ensures sufficient strength and resilience.

Provision is preferably also made for the seat rail to have a first rail element for connection to a chassis of a vehicle and a second rail element for connection to the vehicle seat, the first rail element being movable in the lateral direction relative to the second rail element for longitudinal displacement of the vehicle seat relative to the chassis , wherein the at least one cover strip is correlated with the movement of the second rail element through an indirect or direct connection to the vehicle seat, so that when the second rail element is displaced in the lateral direction due to a longitudinal displacement of the vehicle seat, the at least one cover strip is also at least in the guide bracket moves in the lateral direction, and the guide bracket is directly or indirectly connected to the first rail element, i.e. is fixed to the chassis when installed. Therefore, a conventional seat track can be used for the track assembly to easily provide continuous covering of the seat track as the vehicle seat moves with the guided cover strip.

It can preferably also be provided that the guide bracket has a first bracket part and a second bracket part, which are spaced apart from one another in the horizontal direction and which each extend in the lateral direction, with a horizontally running groove being arranged in each bracket part, with each groove in the lateral direction over the respective mounting part and wherein the at least one cover strip is inserted into the two grooves on both sides, so that a movement of the at least one cover strip at least in the area of the guide mount is made possible in the lateral direction and in the vertical direction and in the horizontal direction is restricted. The grooves or guide means with the same effect make it easy to ensure that the at least one cover strip can essentially only move in the lateral direction and cannot unintentionally slip out of the guide mount and is therefore no longer correctly positioned.

It is preferably also provided that a deflection device, for example rollers with a horizontally aligned axis of rotation, is provided on each side of the guide holder between the respective deflection unit and the guide holder, the deflector being designed so that the at least one cover strip is arranged vertically downwards relative to the guide holder deflect, preferably while maintaining the tape plane. As a result, a targeted deflection of the at least one cover strip below the floor level can be ensured, so that a subsequent deflection can take place below the floor without adverse effects.

wherein the at least one cover strip is guided by the guide bracket in such a way that a movement of the at least one cover strip is permitted at least in the region of the guide bracket in the lateral direction and restricted in a vertical direction and in a horizontal direction when the vehicle seat connected to the cover strip is in is moved laterally,
wherein the at least one cover strip outside of the guide mount in a first deflection area around a first deflection unit and in a second deflection area runs around a second deflection unit, which deflects the at least one cover strip in each case, the two deflection areas being located on opposite sides of the guide bracket in the lateral direction, wherein
the two deflection units are arranged according to the invention in such a way that a strip plane of the at least one cover strip is aligned vertically in the first and in the second deflection region at least after the deflection.

It is preferably also provided that the deflection units are located in the respective deflection area below the floor, with a deflection device preferably being provided on each side of the guide holder between the respective deflection unit and the guide holder, with the deflection device being designed so that the at least one cover strip opposite the guide holder is in vertically downwards below the plane of the floor, preferably while maintaining the belt plane. The function of returning or winding up the tape is thus advantageously shifted under the floor so that the corresponding functional elements are not visible or protected.

Furthermore, a seat arrangement according to the invention as described is provided in a vehicle according to the invention, the seat rail being arranged on a chassis of the vehicle and a floor being arranged above the chassis and below the vehicle seat.

The invention is explained in more detail below using an exemplary embodiment. Show it:

• 1 a seat arrangement in a vehicle in a schematic view;
• 2 a detailed view of a rail assembly in the seat assembly according to FIG 1 ;
• 3 , 4 according to the rail arrangement 2 in a first embodiment; and
• 5 according to the rail arrangement 2 in a second version.

In 1 a vehicle seat 1 is shown, which normally has a backrest 1a and a seat part 1b. The vehicle seat 1 is longitudinally displaceable (in the lateral direction X) relative to a chassis 2 of the vehicle 40, the vehicle seat 1 interacting in a conventional manner with two laterally arranged seat rails 3 for this purpose. Each seat rail 3 has a first rail element 3a fixed to the chassis and a second rail element 3b fixed to the seat part, with the two rail elements 3a, 3b being connected to one another in such a sliding manner (e.g. via rollers) that the second rail element 3b can be moved in the lateral direction X relative to the chassis 2 of the vehicle 40 can be adjusted. As a result, the longitudinal displacement of the vehicle seat 1 can be effected. In addition to this longitudinal adjustment mechanism, a height adjustment mechanism (not shown) can be provided, via which the seat part 1b or the entire vehicle seat 1 can be raised relative to the chassis 2. Any adjustment mechanisms can be controlled electrically or manually.

In a plane F below the seat part 1b is according to 2 and 3 a chassis-fixed floor 4 is provided, below which the rail elements 3a, 3b of the seat rail 3 are arranged. A seat part support 6 fixed to the seat part protrudes through the floor 4 through a slot 5 and is firmly connected to the second rail element 3b below the floor 4 (see Fig. 4 ), so that the seat part carrier 6 can move in the lateral direction X relative to the chassis 2 together with the second rail element 3b. The bottom 4 serves to hide or protect the underlying elements.

In order to prevent objects or dirt from getting through the slot 5 into the area below the floor 4, which can impair the function of the seat rail 3, the slot 5 is covered by at least one covering strip 7; 7.1, 7.2 covered. The at least one cover strip 7; 7.1, 7.2 is guided in a guide holder 8, the at least one cover strip 7; 7.1, 7.2 on both sides along the entire length of the guide bracket 8 in grooves 8a (see Fig. 4 ) of the guide bracket 8 is positioned. As a result, the movement of the at least one cover strip 7; 7.1, 7.2 restricted in the vertical direction Z and in the horizontal direction Y, while a movement of the at least one cover strip 7; 7.1, 7.2 in the lateral direction X is allowed. Equally effective to the grooves 8a, other guide means can also be provided which limit the movement of the at least one cover strip 7; 7.1, 7.2 in the vertical and horizontal direction Z, Y and at the same time can allow movement in the lateral direction X.

The attachment of the guide bracket 8 can be done as in 4 shown in detail, for example, in that an outer first mounting part 8b, which has one of the grooves 8a (outside), is fastened to the chassis-fixed first rail element 3a and an inner second mounting part 8c, which has the other groove 8a (inside), on one separate chassis-fixed guide carrier 9 is attached, with both mounting parts 8b, 8c in the lateral direction X parallel to each other. This ensures that the seat part carrier 6 can be inserted between the two mounting parts 8b, 8c through the slot 5 in the floor 4 and can be moved in the lateral direction X at the same time.

The at least one cover strip 7; 7.1, 7.2 is designed to be flexible, for example in the form of a steel band or a textile band or belt made of natural fibers or chemical fibers, with the textile band possibly also being reinforced with steel cords. Provision is also made for a first end region 7a of the at least one cover strip 7; 7.1, 7.2 is attached and on a second carrier side 6b of the seat part carrier 6, a second end region 7b of the at least one cover strip 7; 7.1, 7.2. This shifts the at least one cover strip 7; 7.1, 7.2 in the lateral direction X in the guide bracket 8 when the vehicle seat 1 is moved longitudinally. The at least one cover strip 7 thus “moves” along with the vehicle seat 1 in the event of a longitudinal displacement thereof, so that a permanent covering of the slot 5 can be ensured.

According to one embodiment (see 3 , 4 ) it is provided that only one cover strip 7 is provided, ie the end regions 7a, 7b belong to a single cover strip 7. As in FIG 3 shown, the cover strip 7 in this embodiment runs from the first end area 7a on the first carrier side 6a of the seat part carrier 6 in the lateral direction X over a first cover area B1 in the area of the guide bracket 8 to a deflection device 10 consisting of two deflection rollers 10a, 10b, which deflect the cover strip 7 in the vertical direction Z downwards to the chassis 2 and thus into the area below the floor 4. The deflection rollers 10a, 10b each have an axis of rotation 10D running in the horizontal Y direction.

A first deflection roller 11 is located under the floor 4 in a first deflection area B2 as a first deflection unit U1, the axis of rotation 11D of which runs in the vertical direction Z, i.e. offset by 90° with respect to the axes of rotation 10D of the deflection rollers 10a, 10b. The cover strip 7 deflected by the deflection device 10 below the floor 4 runs around this first deflection roller 11 so that the alignment of the cover strip 7 between the deflection device 10 and the first deflection roller 11 is rotated by 90°. A strip plane E, in which the cover strip 7 runs, is therefore rotated by 90° in the first deflection area B2 in relation to the strip plane E in the first cover region B1 (X-Y plane).

Starting from the first deflection area B2, the cover strip 7 runs to the side of the seat rail 3 via a return area B3 to a second deflection area B4, with the alignment of the strip plane E being retained in the return area B3 and therefore also offset by 90° with respect to the first cover area B1. Since the cover strip 7 runs to the side of the seat rail 3 in the return area B3 and is not deflected any further in the vertical direction Z (and also in the horizontal direction Y), there is no further deflection downwards, i.e. towards the chassis 2 or under the seat rail 3 itself Space for the return of the cover strip 7 required.

A second deflection roller 12 with a vertical axis of rotation 12D, around which the cover strip 7 runs, is provided as a second deflection unit U2 in the second deflection region B4. The cover strip 7 then reaches a further deflection device 10 with two rollers 10a, 10b with horizontal axes of rotation 10D. Due to the alignment of the two rollers 10a, 10b of the deflection device 10, the strip plane E of the cover strip 7 between the second deflection roller 12 and the deflection device 10 is now rotated again by 90° from a vertical alignment into a horizontal alignment. The cover strip 7 is then guided upwards (in the vertical direction Z) by the deflection device 10 into the plane of the floor 4 to the guide bracket 8 and is guided there over a second cover area B5 to the second carrier side 6b of the seat part carrier 6 .

The cover band 7 thus covers the slot 5 in the base 4 in two cover areas B1, B5, in which the band plane E of the cover band 7 is aligned horizontally, while the band plane E in the return area B3 is not aligned horizontally but preferably vertically, i.e. the band plane E is specifically changed for the return to save space. In order to achieve a smooth movement of the cover strip 7 and to prevent blockages, at least one of the deflection rollers 11, 12 can be spring-loaded.

A space saving in the vertical direction Z can also result from the fact that in a further embodiment, which is shown in 5 is shown, instead of just one cover strip 7, two separate cover strips 7.1, 7.2 are used, without a return taking place via a return area B3. The two end regions 7a, 7b connected to the carrier sides 6a, 6b therefore belong to two different cover strips 7.1, 7.2.

Accordingly, a first cover strip 7.1 in this embodiment runs from the first end area 7a on the first carrier side 6a of the seat part carrier 6 in the lateral direction X over a first cover area B1 in the area of the guide bracket 8 to a deflection device 10 of two Deflection rollers 10a, 10b, which deflect the first cover strip 7.1 in the vertical direction Z downwards to the chassis 2 and thus into the area below the floor 4. The deflection rollers 10a, 10b each have an axis of rotation 10D running in the horizontal Y direction.

A first winding roller 13 with a first shaft 13a is located under the floor 4 in a first deflection area B2 as a first deflection unit U1, the axis of rotation 13D of which runs in the vertical direction Z, i.e. offset by 90° with respect to the axes of rotation 10D of the deflection rollers 10a, 10b . The first cover strip 7.1, deflected by the deflection device 10 below the floor 4, runs around the first shaft 13a of this first winding roll 13, so that the alignment of the first cover strip 7.1 between the deflection device 10 and the first winding roll 13 or the first shaft 13a changes by 90 ° twisted. A strip plane E, in which the first cover strip 7.1 runs, is therefore rotated by 90° in the first deflection area B2 in relation to the strip plane E in the first cover region B1.

When the first winding roller 13 rotates about the axis of rotation 13D, the first cover strip 7.1 is deflected in the vertical direction Z and also wound up or unwound from the first shaft 13a, depending on the direction of rotation. This happens when the seat part carrier 6 is correspondingly displaced in the lateral direction X, the first cover strip 7.1 being wound up by the first winding roller 13 being spring-biased in the corresponding direction of rotation.

In the same way, a second winding roller 14 spring-biased in the corresponding direction of rotation is provided as a second deflection unit U2 in the second deflection region B4 and has a second shaft 14a, whose axis of rotation 14D runs in the vertical direction Z. Depending on the direction of rotation of the winding roller 14, a second cover strip 7.2 is wound up or unwound on this. The second cover strip 7.2 is aligned vertically in the second deflection area B4 and is aligned in the horizontal direction via a deflection device 10 with two horizontally rotating rollers 10a, 10b in order to be horizontally aligned in the guide bracket 8 in the second cover area B5 to the second carrier side 6b of the seat part -carrier 6 to arrive.

Accordingly, there is no return in this embodiment, with the “excess” cover strip 7.1, 7.2 being wound up on the respective winding roll 13, 14. Due to the vertical orientation of the axis of rotation 13D, 14D of the respective winding roller 13, 14, the diameter of the respective winding roller 13, 14 increases only in the horizontal and lateral direction Y as a result of the winding of the respective cover strip 7.1, 7.2 on the shaft 13a, 14a, so that no additional space is required in the vertical direction Z.
