The 1 shows in a synopsis with the 2 a perspective view of a seat 100 With a flexible seat on the seat part and on the backrest side thanks to the use of a knitted structure 10 .

The seat 100 comprises two contour-giving seat components which are dimensionally stable due to their predeterminable geometric configuration 101 and 102 .

The first dimensionally stable seat component 101 is designed as a contouring legrest element, it being pointed out that the legrest element according to the invention only covers the front area (compare in advance 2 ) of a seat part 12th of the seat 100 forms.

The second dimensionally stable seat component 102 is designed as a contouring head and shoulder part, whereby it should be noted that the head and shoulder part only covers the upper area (compare in advance 2 ) of a backrest part 14th of the seat 100 forms.

The first dimensionally stable seat component 101 is designed in one piece or in several pieces, which will be discussed in more detail below.

A one-piece first dimensionally stable seat component 101 (not shown) comprises two interconnected leg rest legs.

A multi-piece first dimensionally stable seat component 101 as shown in 2 comprises two separately arranged leg rest legs 101A .

The second dimensionally stable seat component 102 is also designed in one piece or in several pieces, which will also be discussed in more detail below.

A one-piece second dimensionally stable seat component 102 includes (compare also 2 ) a basic part 102A , a headrest part 102B with side support parts and a shoulder leg part 102C with side shoulder thighs.

The contour of the headrest part 102B is designed in such a way that a dimensionally stable headrest contour of a headrest 16 is trained.

The contour of the shoulder thigh parts 102C is designed in such a way that a dimensionally stable backrest part contour in the upper area of the backrest part 14th is formed as the head and shoulder part 102B , 102C only the upper area of the backrest part 14th of the seat 100 forms.

A multi-piece second dimensionally stable seat component 102 as shown in 2 comprises two shoulder leg parts arranged separately from one another 102 , a basic part 102A and a headrest part 102B . As a multi-piece second dimensionally stable seat component 102 becomes a seat component 102 whose parts are arranged separately from one another or whose parts are initially individual parts and which are joined together to form an assembly part.

Another essential aspect of the invention is that the first dimensionally stable seat component 101 not with the second dimensionally stable seat component 102 communicates.

In other words, the contouring leg support element 101 , 101A and the contouring head and shoulder part 102 , 102A , 102B , 102C are independent components and not directly connected to each other.

The third dimensionally stable seat component 103 forms the seat 100 , this being the third seat component 103 is a deflection device with deflection elements, which in the embodiment as deflection rollers 103A are trained. The pulleys 103A can on a deflection axis Y103 rotate.

A difference according to the invention between the first and second seat components 101 , 102 to the third seat component 103 is that the first and second seat components 101 , 102 are arranged in a fixed position on a structure, while the third seat component 103 Although it is also arranged in a fixed structure, the deflecting device or the deflecting elements can move in at least one spatial direction x, y, z, preferably in -x-direction and + x-direction and -y-direction and + y-direction as well as in - move z direction and + z direction as in 2 using the arrow on one of the pulleys 103A is made clear. The movement of the deflectors 103A is caused by drives not shown in detail.

Under a structurally fixed arrangement of the seat components 101 , 102 , 103 becomes an arrangement of the seat components 101 , 102 , 103 understood on a common structural component, for example, a common frame, which in turn is connected to a vehicle structure.

However, the invention advantageously provides that the seat components are not connected via a relatively heavy frame, but that the seat components 101 , 102 , 103 be arranged separately from one another on the vehicle structure, the following arrangement variants being proposed.

The first seat component 101 (one or more pieces) is preferably fixed in position to the vehicle structure on the floor (vehicle floor).

At least one base part (not shown) of the third seat component 103 (in one or more pieces) is also preferably fastened in a fixed position to the vehicle structure (vehicle floor) on the floor, whereby it is ensured that the deflection elements are located 103A with respect to the at least one base part in at least one spatial direction - / + x , - / + y , - / + z by a specifiable amount, from a starting position (on the axis Y103 ) of the deflection elements 103A starting, can move, taking on the function of these degrees of freedom of movement - / + x , - / + y , - / + z the deflection elements 103A will be discussed in the further description.

The second seat component (one or more pieces) is preferably fixed in position on a roof-side vehicle structure (vehicle roof) or a side (vehicle B-pillar) or another in the upper and / or side area of the vehicle structure (roll cage or roll bar).

The seat components 101 , 102 , 103 conceptually form the prerequisite for a seat 100 with a contourable seat part 12th and a contourable backrest part 14th to accomplish.

With "contourable" or "contourability" is meant the function according to the invention, which consists in that the outer contour of the seat part 12th and / or the backrest part 14th can be changed in a special manner according to the invention, as will be explained below.

Seat part 12th and backrest part 14th have according to the invention by the arranged knitted structure 10 a flexible and between the seat components 101 , 102 running stretched seat part surface and backrest part surface.

The concept according to the invention is based on the idea that a type of hammock is symbolically arranged in a seat, which according to the invention is a “contoured hammock”.

With reference to 2 , in which a perspective view of the structure of the seat 100 with a flexible seat on the side of the seat and the backrest, omitting the in 1 shown knitted structure 10 is attached, it becomes clear that the seat 100 also two contouring adjustment systems 10S and 10G includes.

Both systems 10S , 10G are based on the idea that the associated adjustment elements S. , G in a starting position between two predeterminable articulation points PA1 , PA2 or articulation points PA1 , PA2 and at least one turning point PU1 have a predeterminable length, whereby the seat part surface and backrest part surface and the outer contours of the seat part surface and backrest part surface of the seat part 12th and the backrest part 14th are in their starting position.

Since the seat part surface and the backrest part surface and the outer contours of the seat part surface and backrest part surface of the seat part 12th and the backrest part 14th due to the knitted structure 10 are formed, there is thus the knitted structure 10 in the specified starting position.

Starting from the explained starting position, both systems are 10S , 10G designed as traction systems that are attached to the adjustment elements S. , G pull to effect an adjustment in an adjustment position, wherein the adjustment can be reversed from the adjustment position to the starting position.

The first system is preferred as a belt pull system 10G and the second system is preferred as a rope pull system 10S educated.

With the belt pull system 10G (compare 2 ) are used as adjusting elements flat belts G and the rope pull system 10S become ropes S. used.

• Die Seile S des Seil-Zugsystems 10S sind gemäß dem gewählten Ausführungsbeispiel einendseitig fest an dem Anlenkpunkt PA1 und längenveränderlich an den Anlenkpunkten PA2 angelenkt. Die Seile S sind jeweils einendseitig fest an den Beinauflageschenkeln 101A in ihrem oberen Bereich der Beinauflageschenkel 101A angeschlagen. Am gegenüberliegenden Ende der Seile S ist ein Verstellorgan, insbesondere ein Antrieb bevorzugt in dem Basis-Strukturteil 102 versteckt angeordnet und ortsfest an dem Basis-Strukturteil 102 befestigt, der eine Zugkraft auf das jeweilige Seil S ausübt, wenn eine reversible Veränderung der Kontur des Randbereiches der Gestrick-Struktur 10 vorgenommen werden soll. Als Verstellelement kommt eine Art Seilaufrollsystem (je Verstellelement) in Frage, welches die Seile S kontinuierlich aufrollt und in der gewünschten Verstellposition fixiert und nach einer Freigabe wieder langsam kontinuierlich freigibt, sodass wieder die Ausgangsposition oder eine Position zwischen der maximalen Verstellposition und der Ausgangsposition erreicht ist.

In detail:

• The ropes S. of the rope pull system 10S are fixed at one end to the articulation point according to the selected embodiment PA1 and variable in length at the articulation points PA2 hinged. The ropes S. are firmly attached to the leg rest legs at one end 101A in their upper area of the leg support legs 101A posted. At the opposite end of the ropes S. is an adjusting element, in particular a drive, preferably in the basic structural part 102 arranged hidden and stationary on the basic structural part 102 attached, which a tensile force on the respective rope S. exerts when a reversible change in the contour of the edge area of the knitted structure 10 should be made. A type of cable winding system (for each adjustment element) can be used as the adjusting element, which the ropes S. rolls up continuously and fixed in the desired adjustment position and slowly and continuously releases again after a release so that the starting position or a position between the maximum adjustment position and the starting position is reached again.

The straps G of the belt pulling system 10G are fixed at one end to the articulation point according to the selected embodiment PA1 hinged. They are preferred over the rope pull system 10S via the deflection elements 103A at the turning points PU1 diverted. The straps G are also variable in length at the articulation points PA2 hinged.

The straps are in accordance 2 at one end firmly to the leg rest legs 101A in the lower area of the leg rest 101A posted. At the opposite end of the straps G is an adjusting element, in particular a drive, preferably in the basic structural part 102 arranged hidden and stationary on the basic structural part 102 attached, which exerts a tensile force on the respective belt G exerts when a reversible change in the three-dimensional position of the seat part surface and the backrest part surface of the seat part 12th and the backrest part 14th in the space of the knitted structure 10 should be made. A type of belt roll-up system (for each adjustment element) can be used as the adjusting element, which the belts G rolls up continuously and fixed in the desired adjustment position and slowly and continuously releases again after a release so that the starting position or a position between the maximum adjustment position and the starting position is reached again.

In other words, the straps G are over the deflection elements 103A at the turning points PU1 about the rotating axis Y103 deflected and give the seat 100 by tensioning or loosening the belts according to the previous explanation, its contour and also the comfort and the desired position of the knitted structure 10 , which determines the sitting position of a user, who is thus advantageously by means of the cable pull system 10S the edge-side contour and position and by means of the belt-pulling system 10G the two-dimensional contour and position of the knitted structure 10 can determine advantageously independently of one another or advantageously in combination.

Two ropes for each adjustment element S. and two straps G , an adjusting element (not shown) is assigned to each.

According to the invention it is provided that the knitted structure 10 preferably has integrated channels in its structure through which the ropes S. and / or straps G between the articulation points PA1 , PA2 or between the articulation points PA1 , PA2 and the at least one turning point PU1 be passed through.

In embodiments it can be provided that the ropes S. and / or the straps G of the train systems 10S , 10G partly inside and partly outside of the knitted structure 10 run, especially the straps G can run or be arranged below the seat part surface (not integrated into the knitted structure) or behind the backrest part surface (not integrated into the knitted structure).

In the illustrated embodiment, the belts step G from the knitted structure 10 in the area of the deflection device with its deflection elements 103A from the knitted structure 10 out. It is also conceivable that the deflection device with its deflection elements 103A in the knitted structure 10 is arranged enclosed so that the axis Y103 different than shown in the figures by the knitted structure 10 runs.

In the further 3 to 5 The same reference symbols are used below for the same components, although not all components already presented are explained again in the following description with reference to the reference symbols.

The 3 shows again the structure of the seat in its perspective representation 100 with a flexible seat on the seat part and on the backrest side with a transparent representation of the knitted structure 10 according to the 1 and 2 to illustrate an area-wise reinforcement of the Knitted structure 10 according to a "first" variant.

According to the invention it is provided that the knitted structure 10 is air permeable.

It is also provided that certain zones are knitted more densely and padded in order to protect sensitive areas of the user sitting on the chair (e.g. the kidneys).

Furthermore, it is provided according to the invention that certain zones Zn , Z1 , Z2 , Z3 (n = number of zones Z) knitted more densely and not only padded, but knitted more tightly to create more solid zones Z1 , Z2 to build.

In 3 is an example of a more tightly knitted zone Z1 shown showing an increased force absorption of the knitted fabric structure 10 in the area of the leg support element of the seat user 100 guaranteed.

In 3 is another example of a more tightly knitted zone Z2 shown showing an increased force absorption of the knitted fabric structure 10 in the area of a lordosis of the seat user 100 guaranteed.

In addition, in 3 for example another more tightly knitted zone Z3 shown showing an increased force absorption of the knitted fabric structure 10 in the area of the back of the head of the seat user 100 causes.

The 4th shows analogously to 3 a perspective view of the structure of the seat 100 with a flexible seat on the seat part and on the backrest side with a transparent representation of the knitted structure 10 according to 1 to illustrate a region-wise reinforcement of the knitted structure according to a "second" variant.

In contrast to the in 3 shown knitted fabric structure 10 is according to 4th in the mentioned zones Zn , Z1 , Z2 , Z3 a thin strap G' knitted into the in 3 zones shown achieves the desired effects.

The 5 shows yet another embodiment of the invention in a further perspective illustration of the seat according to FIG 1 , but with an advantageous sensor network structure 20th .

In the knitted fabric 10 sensory yarns are integrated, which form the sensor network structure 20th and make it possible to read out the sitting position, the weight and the pressure distribution of a person sitting on it.

Thus, a person's sitting posture becomes the position of the knitted structure 10 or that via the belt / cable system 10S , 10G is adjustable, after analysis of the sensory data perfectly to the body contour of the person on the seat part side and / or the backrest part side, in particular advantageously also adapted to the driving situation, since the sensor data change accordingly for a seated person in different driving situations (e.g. cornering).

It is also provided that a control device, in particular an on-board computer, communicates haptically with the person sitting on it via driver assistance systems and converts these haptic signals into adjustment commands for the belt and / or cable systems 10S , 10G in adjustment movements of the ropes / belts S. to be translated.

The tension of the knitted fabric 10 is chosen in such a way that it bears the person's weight, with the riding forces via the seat components 101 , 102 , 103 can be derived into the body.

Advantageously, it is possible that the ropes S. on the seat flanks of the seat part 12th and / or that of the backrest part 14th the seat 100 Define the outer contour or optimize the lateral support of the person sitting on it.

Furthermore, it is provided in an embodiment according to the invention that in an advantageous manner by lowering the outer contour, in particular the seat flanks of the seat part 12th and / or optionally the seat surface of the seat part 12th by means of the belt and / or cable systems 10S , 10G getting on and / or off a person when getting in or out of a vehicle is simplified.

Both systems 10S , 10G are operated via servomotors, which are not shown in the figures.

The servomotors are preferred for each rope S. and every strap G , one actuator each together in a cavity of the base part 102A arranged. In the figures are the ropes S. and the straps G up to the base part 102A out and end there, not as shown with a free end, but open with their upper articulation points shown PA1 , PA2 in a rope belt retractor 10S , 10G , which each have at least one servomotor around the ropes S. and the straps G to roll up and thus shorten or which the ropes S. and the straps G only release or actively roll and extend. Will the ropes S. and the straps G only release, for example, a ride-on force ensures that the ropes roll off accordingly S. and straps G . In other words, with the belt and / or cable systems 10S is the seat contour of the seat part 12th and the backrest part 14th as well as the position of the Seat part 12th and the backrest part 14th and the associated headrest 16 adjustable in three-dimensional space.

The main advantages of the frameless seat with the knitted structure are a seat design that allows the seat 100 is light and in terms of its weight comparable to a carbon bucket seat; the comfort is comparable to an upholstered standard seat; the frameless construction allows a high degree of flexibility in the shape and geometry of the seat 100 achieved, whereby an individual and intelligent adaptation to body shape and driving situation is made possible, wherein the contour of the seat can adapt to the driving situation or the driving situation adapts to the detected contour of the seat, as explained above. By analyzing the sensory data, the seat is 100 or the contour and / or the position of the seat part 12th and / or the backrest part 14th with the headrest 16 perfectly adaptable to the body contour of the person on the seat part side and / or the backrest part side, in particular the seat can advantageously also be adapted to the driving situation, since the sensor data for a seated person change accordingly in different driving situations (e.g. cornering). On the other hand, the driving situation can also affect the contour and / or the position of the seat part 12th and / or the backrest part 14th with the headrest 16 be adapted, that is, a contour and / or the position of the seat part 12th and / or the backrest part 14th with the headrest 16 If, for example, appears to be unfavorable for a specific driving situation, the driving situation can be changed. For example, the speed is reduced or the speed is only further increased if a certain contour and / or the position of the seat part 12th and / or the backrest part 14th with the headrest 16 has been set.

Last but not least, the textile, and therefore the knitted structure, which is also used as a cover, is advantageously easy to exchange and is therefore “environmentally friendly” and also easy to manufacture compared to expensive foam padding parts on frame structures.

Another advantage is that it can be adjusted by the additional adjustability of the leg support legs 101A the seat component 101 In the height +/- z-direction and in or against the direction of travel +/- x-direction, different body sizes can be taken into account and the leg support legs are adjusted 101A to approach, with the adjustment of the leg rest legs 101A regardless of the adjustment of the ropes S. and straps G by means of the rope and / or belt winding systems 10S , 10G or in combination with adjusting the ropes S. and straps G by means of the rope and / or belt winding systems 10S , 10G is made.

Due to the additional adjustability of the distance (in y-direction) of the straps G on the rotating deflection axis or belts G on the pulleys 103A below the seat part 12th it is also possible in an advantageous manner to adjust the seat to different hip and body widths. To adjust the width, the on the deflection axis Y103 deflected belts G by means of the pulleys 103A (in +/- y-direction) closer to each other or further (from each other, compare 2 ) guided.

Due to the additional adjustability of the deflection axis Y103 (in the x-direction and / or in the z-direction) of the belts G on the pulleys 103A below the seat part 12th it is also possible in an advantageous manner to adjust the seat to different hip points (H points). The deflection axis is used to adjust the hip point Y103 with the belts deflected around it G by means of the pulleys 103A (in +/- y-direction) up or down (+/- z-direction) and / or backwards or forwards +/- z-direction (compare apart 2 ) relocated.

The design of the seat according to the invention thus enables weight to be saved by eliminating complex frame structures and complex adjustment mechanisms and the upholstery material, with a very flat seat structure also being formed. The components of the legrest, that is to say the legrest legs, can preferably be used 102A and the components of the head part, i.e. the base part 102A and / or the headrest part 102A and / or the shoulder leg parts 102C can be produced in one piece or in several parts in a 3D printing process and can thus be easily produced in an individualized manner.

In a further advantageous manner, it is also possible by adjusting the leg support legs 101A and the ropes S. and straps G of the rope and belt retraction systems 10S , 10G the seat 100 to bring from the sitting position to the lying position and vice versa.

A rotation of the body takes place around a shoulder axis Y102 (compare 2 ) not at the hip point, but at the shoulder point of a sitting person, with the shoulder point on the shoulder axis Y102 lies. This enables a change from a sitting position to a lying position. For example, there is no restriction of those sitting in the rear if the driver of a vehicle wants to move into a lying position, since the position of the seat component changes 101 does not change, so that the free area in the rear, that is, behind the seat 100 preserved. The possibility of adjusting the Sitting in a lying position and vice versa is a significant advantage, especially in future autonomous vehicles.

The sensory knitted fabric is also ideally suited for passive air conditioning. Knitted fabric is air-permeable, but can be knitted more densely and padded in sensitive areas (e.g. kidneys).

The basic idea of the seat designed according to the invention 100 consists, as already explained, in the design and arrangement of the knitted structure 10 as a "contoured hammock" that sits between two dimensionally stable seat components 101 and 102 is arranged, the seat components 101 , 102 are not directly connected to each other. A third seat component 103 is designed as a deflection device, which allows the seat shape / seat contour to be adapted to the seated person and the driving situation and vice versa to a significantly greater extent.

The combination of knitted structure 10 , the belts G and ropes S. or the belt pull system 10G and the rope pull system 10S allows the size of the person, the sitting position and other settings, such as the adjustment of the backrest angle, to be made using the simply constructed pulling system 10G , 10S make, with the seat components 101 and 102 only about the knitted structure 10 and the straps G and ropes S. are indirectly connected to each other. The individual seat components can be easily separated from one another so that individual seat components and parts can advantageously be exchanged.
