Description

Austrian Patent Office AT505 212B1 2010-11-15

The invention relates to a seat, in particular for public transport, with a support frame and an associated support unit, which comprises a base frame and an elastic fabric supported thereon and this is formed as a self-supporting construction of a fabric and the fabric a Supporting surface with a seating area and a back region is formed, wherein the covering is formed continuously between the seat area and the back area and the support surface of the fabric in the longitudinal direction has a plurality of successively arranged zones, of which at least one zone has a greater elastic deformability with respect to the other zones.

From WO 99/43239 A1 or the EP 1 056 371 B1 issued therefrom, a covering for a sunbed has become known, which has a peripheral support or support frame for receiving and supporting the fabric. The fabric is in turn made of a textile structure made of a fabric made of plastic threads fabric or fabric. This fabric is supported under different bias on the longitudinal beams of the support frame, wherein viewed in the longitudinal direction of the longitudinal beams sections are provided with different bias. Due to the differently selected bias of the textile structure zones with different elasticity are created in the longitudinal direction. In the case of the bed shown here, in the region of the highest load application, namely in the area of the buttocks, the preload is selected to be the highest, resulting in the lower elasticity and thus lower sinking.

The US 4,230,365 A describes a piece of furniture from a self-supporting frame and a continuous, the frame parts enveloping textile cover. The textile cover material is formed of a knitted material having elastic properties.

The side frame members are connected to each other via cross braces, wherein between the fabric cover and the cross braces an additional foam pad is arranged for support. The textile cover serves purely to cover the frame parts and has no self-supporting function and zones of different deformability for the support of the user.

From US 3,999,802 A, a chair made of a tubular frame frame is known, which is surrounded in its seat and back by a coating material. This is drawn in the form of a textile tube over the tube frame. In the transition region between the seat and back cross braces are provided. For ease of assembly, the sack-formed covering material has an opening in the end facing the knee region so as to be pulled over the frame and mounted thereon. The textile cover has no zones of different deformability for the support of the user.

From US 2,865,436 A1 discloses a seat made of a frame and a cover material has become known, in which the intended for sitting cover material is held by means of elastic clamping elements laterally to the frame members. The elastic properties of the cover material are realized only by the arranged in the region of the two longitudinal sides elastic traction elements, so as to achieve a certain compliance.

US 3,600,035 A describes a covering material for a seat part of a frame, wherein the frame in the transition region between the seat and the backrest has a transverse between the lateral frame members strut element. The covering material has a solid, almost unyielding supporting body in order to be able to transfer the weight of the person sitting thereon to the frame. Between the cover layers of the coating material, an additional foam part is arranged to improve the comfort even more. The cover or the covering has no zones of different deformability for the support of the user. 1/36 Austrian Patent Office AT505 212B1 2010-11-15 DE 202 16 302 U1 describes an office chair with a tiltable backrest, which has an elastic covering. The backrest comprises a backrest frame to which the fabric is attached. This fabric is formed as a tubular knit, wherein the center for supporting the back has a higher elasticity than the surrounding edge zones. This makes it possible for the user, in the center region of the fabric in the reclined position, to deform the back part deeper into the knitted fabric than is possible in the edge zones. The seat consists of a seat support on which the seat cushion is stored. The seat and the backrest each represent their own but interconnected components.

From DE 34 03 967 A1 discloses a vehicle seat with its own seat part and backrest part has become known in which both the seat surface part and the backrest part has zones of different compliance. The zones of the various compliance are divided into two seat parts in tracks. The seating area has in its center a high compliance and thus higher elasticity than the two directly adjoining front and rear zones. The entire seat is laterally and at its back surrounded by a U-shaped outer zone, which has the lowest yield and thus the highest strength compared to the other zones. Also, the back region has a surrounding this outer, approximately U-shaped edge zone with the least flexibility and thus highest strength. The back region itself is formed in zones with different but higher compliance with respect to the outer zone. The zones of different strength are formed from stuffed with padding material, closely spaced chambers or hoses.

From US 4,522,447 A seat and back upholstery of a foam material have become known, wherein the seat cushion in the immediate support of the seating area this has the highest elasticity. This central zone is surrounded by a foam material with a higher modulus of elasticity and thus this has a higher strength.

Is a chair known whose seat and back part has laterally extending support or support elements, which in turn are supported by each having feet and a backrest element having U-shaped parts. Between the lateral supporting or supporting elements prestressed spring elements and transverse struts are arranged, wherein the transverse spring elements serve to support the continuously formed support. Between the layers forming the overlay is an additional filling or. Padding material introduced in the seat or the backrest forming sections. The greatest compliance is achieved by the transverse spring elements by load transfer, starting from the continuous support on this. In order to achieve a length compensation during use of the continuous support, the two arranged on the underside of the seat ends are connected to each other by means of an elastic connecting element in the form of a tension spring. As a result, a length compensation during use can be achieved.

Also WO 2008/023228 A1 describes a seat unit of a seat and back part. Both the seat and the back part in turn comprise their own elastically formed support parts, which are covered by a continuously formed coating material. In the transition region between the seat and back part of the coating material is wrapped over a cross brace and then continuously extending over the back part extending to the rear side arranged. The load transfer takes place starting from the coating material on the elastically formed support parts of the seat or the backrest.

From EP 1 680 981 A1 a chair with a one-piece seat and back from a curved shell frame tube is known. To support the user, a one-piece knitted fabric with a circumferential welt hem is used. The curved shell frame tube is received in the circumferential Kedersaum, wherein in the popliteal region, the fabric has at least one opening, so as to keep the ends of the shell frame tube by means of a tie rod at a distance. In this case, the fabric between the seat and back area is arranged continuously and has a uniform strength.

The US 2004/0160109 A1 describes a chair whose seat and back are formed by a frame part, which is surrounded by a bag-shaped enclosure. This enclosure forms the fabric for the chair and is arranged continuously between the seat and back. The edge portion of the clothing facing the support frame has a lower elasticity than the two layers forming the support.

From US 5,013,089 A a seat assembly has become known, which comprises a support frame and a plurality of frame members for forming the seat and back part. The two the seat and back frame forming frame parts are each formed by their own, all-round frame. The two frame parts are connected to each other via support brackets to a seat frame. The seat and the back surface are each covered with a content held on the frame part fabric to form the seat or back rest. Due to the two frame parts for the formation of the seat and back part of an individual ingestion of different seating positions is not possible.

Seats with upholstery made of foam plastic are very widespread in modern vehicle construction. Above all, they are used in rail and road vehicles, but also for the most part in aircraft. While regulations governing the self-extinguishing design of materials used or the development of smoke dictate very stringent guidelines for rail vehicles, they are far exceeded by the regulations applicable in the aircraft industry. For example, in the case of seats approved for use in aircraft, a test is required in which the cushions, in their intended equipment, are directly exposed to a flame from a burner. This flame acts directly on the cushion over a period of 2 minutes, after which the flame is extinguished or removed. The upholstery will be deleted after 5 minutes, if by that time the flames have not extinguished themselves. After this burn test, the weight loss of the pad must not exceed 10%. In order to meet these extremely strict regulations, while at the same time achieving a high seat comfort in the seats during the long-lasting air travel and a low weight, seat cushions were glued together from different, flame retardant, open-line elastic flexible foam plastics with different densities.

The present invention has for its object to provide a seat that has improved comfort at lower weight and allows different positions of use for the user.

This object of the invention is achieved in that the zone is formed with the greatest elastic deformability between the seating area and the back area and that in a longitudinal edge region of the fabric on both sides of the zone forming the seating area each have a further strip-shaped edge portion of the zone with the largest elastic deformability is arranged. The advantage resulting from the features of claim 1 lies in the fact that for the user in the upright sitting position the possibility is created to be able to stretch the clothing sufficiently and so far during use that the user sinks into the fabric stretched on the frame is possible. This high elastic deformability of the knitted fabric allows the user to sink in between the laterally arranged frame parts into the fabric and nevertheless achieves optimum support over the entire supporting or supporting surface of the user. The adjoining zones of the seat and back region have with respect to the zone with the greatest elastic deformability to a lower deformability, whereby here a corresponding back pressure of the fabric during use is exerted on the user. Furthermore, in the region of the seat in its edge region, a zone with high elasticity is available, which allows a controlled sinking or folding down of the entire seat in the direction of the seat unit. Due to the continuous between the seat and the backrest stringing disturbing frame parts 3/36 Austrian Patent Office AT505 212 B1 2010-11-15 be avoided for taking different positions of use. This creates the possibility for a user to use the entire, continuously formed fabric for its support on the seat and to be able to assume individual seating positions without any adjustment of a seat part. By arranging a plurality of different zones over the longitudinal or transverse extent of the knitted fabric, the elastic deformability of the fabric can be adjusted so that with a fixed backrest with respect to the seat frame still different sitting or lying positions can be taken. Due to the different elastic formability of the individual zones, the desired support of the user can be specified on the fabric for different positions of use, without requiring an adjustment of a frame part of the seat is necessary. In addition, the fabric designed as a knitted fabric for the support of the user requires a much smaller volume than previously used foam plastic upholstery, whereby here for the combustion behavior is a negligible amount of materials, which is a possible burnup and the associated Are exposed to smoke.

A further advantage is an embodiment according to claim 2, as so within certain limits already a very low tensile force, a high elongation of the fabric can be achieved in this area and still sufficient support during use is ensured.

By the formation of claim 3, it is possible to accurately predict the stretching behavior of the elastic zone can.

According to another embodiment according to claim 4, an optical unit of the entire clothing is achieved despite different elastic properties.

In the embodiment according to claim 6 is advantageous that so a fabric can be created, which ensures the user a high level of comfort even for longer-lasting flights.

Through the development according to claim 7 it is achieved that so adapted to the shape of the human body seating area can be created, which still allows sufficient elastic deformability.

By the construction according to claim 8, the stretching behavior and thus the available number of stitches of the knitted fabric can be determined or predetermined.

Also advantageous is an embodiment according to claim 9, as this sufficient support of the user can be achieved in the area of the seat and still sufficient seating comfort can be achieved.

According to an embodiment as described in claim 10, a fabric can be created, which ensures the user a high level of comfort even for longer-lasting flights.

According to an advantageous embodiment according to claim 11, the proportion of highly elastic zone is increased, whereby an even more uniform sinking of the user is made possible in the fabric.

Another advantage is also an embodiment according to claim 12, since it can be found with few components to form the seat Auslangen and so the total weight of the seat can be further reduced. In this case, a sufficient support is also achieved for the covering, whereby an optimal load transfer from the fabric towards the support unit takes place.

According to claim 13 can be dispensed with complicated adjustment mechanisms between the back rest and the seating area, since different sitting or reclining positions exclusively by the different elasticity and the stretching behavior the covering is made possible.

In the embodiment according to claim 14 can be easily taken into account for different conditions of use of the seat, the always fixed angle allows a simple, cost-effective frame construction.

It is also possible an embodiment according to claim 15 because thereby that path is minimized, which covers a user while sitting on the seat to the first contact on the fabric. Furthermore, even better support during use in the manner of a bucket seat in the fabric is achieved.

The embodiment according to claim 16 allows a controlled sinking of the user in the seating area. In addition, but also slipping out of the seat during use, especially in severe delays avoided.

Advantageously, the embodiment according to claim 17, characterized because of the covering and the base frame, a unit can be created, which can be provided pre-assembled for the cleaning staff or service personnel.

But is also advantageous training according to claim 18, as this is simply a replacement in case of contamination or destruction of the fabric allows.

Also advantageous is a further embodiment according to claim 19, since a more stable training of the seat can be achieved and certain support or support functions can be transmitted from the cladding element to the base frame. Thus, the cladding element can be made lighter and less stable.

A further advantage is an embodiment according to claim 20, since a direct contact with the inner surface of the cladding element can be damped by the intermediate layer in case of excessive load or heavy users.

Due to the construction according to claim 21, it is possible to easily coordinate the support behavior of the fabric and the liner to each other.

According to another embodiment according to claim 22 too strong elastic deformation of the fabric is prevented in certain areas for the user and thereby increases the maximum supporting force of the fabric in cooperation with the or the support belt (s). Likewise, it can also be used to prevent springing or hitting the user together with the covering on the cladding element.

Also advantageous is a development according to claim 23, since it is increased for the user of the free space for accessibility and seating on seat. After the appropriate unfolding the seat is increased to the full extent and thus achieved sufficient support in the popliteal region.

In the embodiment according to claim 24 is advantageous that in combination with the fabric and the pivotable frame part a sufficiently stable support during use of the seat for the user is ensured.

The development according to claim 25 ensures that sufficient space can be created for access to the seat or row of seats and still no disturbing parts are present in the region of the seat. So it is possible to put objects on the remaining seat provisionally.

Due to the construction according to claim 26, the pivoting movement of the frame part for the user can be easily made possible.

Also advantageous is an embodiment according to claim 27, since so avoided any operating operations for the user and the pivoting of the frame part between the standby position and the position of use can be carried out automatically. The 5/36 Austrian Patent Office AT505 212B1 2010-11-15

Recognition can be done here, for example, by weight, wherein when removing the weight of the frame part folded down and when using and loading the seat with a weight of the frame part and thus the support section folded up in the position of use is arranged.

According to an embodiment as described in claim 28, an even better support of the user's head on the seat is achieved.

In this case, an embodiment according to claim 29 proves advantageous, because it is thus easily made possible for a user to achieve a cup-shaped receptacle with respect to the head by the adjustable side parts and thus ensure sufficient support in the temple area at a rest position.

According to an advantageous embodiment according to claim 30, a tilt adjustment of the headrest is made possible with respect to a vertical, and thus achieves an even better adaptation to different body sizes of users.

Finally, however, a training as described in claim 31 is possible to easily perform a height adjustment of the headrest can.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis transferred to like parts with the same reference numerals or identical component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

In Figs. 1 to 3 is a seat 1, for example in a public transport, such. an airplane, a railway, a tram or the like., Shown schematically simplified. It would also be possible to use this seat 1 e.g. in other public transport, such as a subway or a car. Regardless of this, however, the seat 1 could also be used as seating in function rooms such as theaters, congress halls, public event halls, multi-purpose buildings, etc. even when omitting and / or adding some of the components described in more detail below.

In this embodiment shown here for the sake of clarity, only a single seat 1 is shown for a user, not shown, but it is possible to arrange a plurality of seats 1 formed side by side to a related row of seats as well as several consecutively.

This seat 1 comprises a support frame 2, which is supported on a contact surface 3 shown in simplified form or supported on or in this. On the presentation of various connectivity was omitted for the sake of clarity, and these are freely selectable from the known prior art and can be used. The seat 1 has a user side facing the user as well as accommodating it for sitting and / or lying, as well as a rear side 5 facing away from it. The back 5 is turned to another user who is located at several, consecutively arranged seats 1 immediately behind this. The seat 1 further comprises a base frame 6 and a cladding element 7, which together form a support unit 8. Preferably, the cladding element 7 is connected to the support frame 2 or held on this, wherein the base frame 6 can be received by the cladding element 7. In this case, the cladding element 7 is arranged in the region of the rear side 5 of the seat 1. The support unit 8 may further be rigid in itself, with any adjustment being made relative to the support frame 2 here.

The user side 4 of the seat 1 forms a support surface 9 or receiving surface for the user of the seat 1. This support surface 9 is formed in this embodiment shown here by a fabric 10, for example in the form of a knitted fabric 11. This covering 10 serves to support the user and is continuous here, starting from a back region 12 towards a seating area 13. This has the advantage that in the transition zone between the back and seat area 12, 13 no cross member of the base frame 6 is arranged and thus only the fabric 10 is used to support and accommodate the user. In the unused initial position of the fabric 10, the back region 12 and the seat region 13 enclose therebetween an angle 14 which is in a range with a lower limit of 90 °, in particular 110 °, preferably 125 ° and an upper limit of 180 °, in particular 150 °, preferably 135 °. A value of the angle 14 may also be between 128 ° and 132 °.

The base frame 6 in the portion of the back region 12 is opposite to a vertical vertical 15 shown at an angle 16 in an area with a lower limit of 0 °, in particular 20 ° and an upper limit of 45 °, in particular 30 ° inclined. This angle 16 with respect to the vertical 15 is dependent on the embodiment or use of the seat 1, but always fixed in the particular application for the user and designed for this unchangeable. As a result, complicated adjustment mechanisms are eliminated as in otherwise conventional aircraft seats. The still different sitting or resting positions are made possible solely by the special design of the fabric 10.

The relative to the vertical 15 also rigidly trained portion of the base frame 6 in the back portion 12 is located in the intended always fixed use position in an angular position with respect to the vertical 15, which in passenger traffic as so-called "computing position". is usually referred to and is set only by its own deliberate adjustment of at least one seat part in conventional seats. Thereby, a larger angle 16 with respect to the vertical 15 in the back region 12 of the fabric 10 is formed with respect to the normal upright sitting position in conventional seats.

As already described above, the covering 10 continuously forms, starting from the back region 12 toward the seating area 13, the support surface 9 for the user. The detailed description of the fabric 10, in particular when it comes to the knitted fabric 11, takes place below. The seating area 13 can in turn be subdivided into a seat area 17 and a thigh area 18. These previously designated areas in turn form their own zones on the fabric 10, wherein within these zones, a further subdivision can take place. These areas or zones will be described in more detail below.

The fabric 10 can in turn be connected to a variety of mounting options with the fixed base frame 6 and supported on this. This can be done, for example, by a tubular receptacle in the edge regions, a variety Kederlösungen and so on. In this embodiment, the base frame 6, together with the string 10 supported thereon, is connected to the lining element 7, whereby the support unit 8 is formed. As a result, the possibility is created to remove the base frame 6 together with the fabric 10 from the cladding element 7 and make a quick swap in case of contamination and damage.

Regardless, it would also be possible for the stiffening of the cladding element 7 and to facilitate the assembly or disassembly of the fabric 10 on the seat 1, in particular on the cladding element 7, this supported on its own additional Besspannungsstragrahmen 19 and is connected thereto , The stringing support frame 19 may in turn be detachably connected to the base frame 6 when the base frame 6 is connected to the lining element 7 and forms the support unit 8. As a result, a quick and easy replacement of the entire fabric 10, for example, after contamination or damage of the same is achieved for the cleaning or service personnel.

From a synopsis of Figs. 1 and 2 it can be seen that the front of the knee area of the user facing seat portion 57 of the seating area 13 can be shortened in its length. For this purpose, a variety of options from the prior art have become known. Here, the shortening is achieved by simply folding down the fabric 10 together with the base frame 6 and / or Besspannungsstragrahmen 19. This shortening serves to increase the gap between seats 1 arranged immediately one behind the other for entry and exit for the user. In the standby position, the seat portion 57 of the seating area 13 facing the hollow of the knees is in the folded-down position as shown in FIG. 2. If the user sits on the seat or seating area 13, the folded-down seat portion 57 of the seating area 13 becomes seated Adjusted position shown in FIG. 1, in particular folded up, and assumes its position of use. The adjustment movement is preferably carried out by a 8/36 Austrian Patent Office AT505 212B1 2010-11-15

Pivoting movement of a portion of the base frame 6 and / or string support frame 19. The string 10 makes this deformation due to their elasticity and elongation properties without problems. If the user rises from the seating area, the load on the covering 10 is relieved and the front seating area section is moved back into the folded-down position. Instead of folding down but also a folding up of the front seat portion would be possible, but leads to an additional reduction of the free space in the seating area 13. This adjustment is preferably carried out automatically without a user specifically triggered by the user actuation, since this is a contrary to the usual intuitive Movement directed adjustment process is. The pivoting movement and its implementation will be described below.

Furthermore, the seat 1 comprises laterally of the seating area 13 arranged and simplified illustrated armrests 20, which are also preferably fixedly supported on the support unit 8, in particular the base frame 6 and / or the cladding element 7 and optionally on the support frame 2. Preferably, each seat 1 is assigned its own armrests 20 on both sides. As a result, in a multiple arrangement of seats 1 side by side each of the individual users each provided its own two armrests available.

Above the back region 12, a simplified illustrated headrest 21 is provided, the training and the adjustment thereof are also described in detail below. The headrest 21 of the fabric 10 is arranged upstream on the user side 4.

In the area of the back side 5 of the seat 1, different inputs or devices are provided or arranged for a further user. Starting from the footprint of the most distant area 3 of the seat 1 of this comprises a display element 22, a pivotally mounted table 23, at least one receptacle 24 for magazines or personal items and at least one preferably, however, arranged on both edge portions holding member 25. This holding element 25, for example, for holding bottle or can-shaped objects, in particular for the storage of drinks serve. In the area of the holding element or elements 25, in this exemplary embodiment the lining element 7 has a concave surface 26 that is curved in the direction of the user side 4 and that additionally extends in the longitudinal direction of the back region 12. Through this concavely curved surface 26, it is possible to save various objects in cooperation with the holding element 25 on the seat 1, in particular the cladding element 7 space saving. Furthermore, this also makes it possible for persons with a larger body size to accommodate the angled knee area during use of the following seat 1 there laterally of the seat in these areas. This creates the opportunity for people with longer thighs to take a seat comfortably on the seat 1 and also take a relaxed position. The receiving element 24 and the holding element 25 can also be formed by a covering, which in particular can be made of a knit fabric or the like.

The above-described additional components in the region of the rear side 5, namely the display element 22, the pivotable table 23, and the receiving element 24 are arranged in a recess 27 formed centrally with respect to the width of the lining element 7. This recess 27 has a longitudinal extent in the direction of a backrest 28 formed by the base frame 6 or the stringing support frame 19. Due to the formation of the recess 27, it is possible to form the components described above or the receiving space formed by the receptacle 24 according to the requirements or to order, so as to find in this area or section of the seat 1 with a small overall depth Auslangen ,

In Fig. 4, the seat geometry of the seat 1 in side view, greatly simplified, shown schematically. The base frame 6 or the stringing support frame 19 is shown simplified in the form of a thicker line, wherein in the unloaded state of the covering 10 this approximately in the contour of the illustrated base frame 6 or Besspannungsstrag- 9/36 Austrian Patent Office AT505 212 B1 2010-11- 15 frame 19 has.

In the region of the backrest 28 or its longitudinal course, it is further illustrated that a shoulder region 29 and a head region 30 facing the user are subsequently formed on the back region 12. In the transition between the back region 12 and the shoulder region 29, the base frame 6 or the stringing support frame 19 has a kink, whereby a flatter angle 31 is formed between the head region 30 and the vertical 15 than the angle 16 between the back region 12 and the vertical 15 The longitudinal course of the base frame 6 or of the stringing support frame 19 is selected starting from the head region 30 toward the thigh region 18 such that in combination with the fabric 10, in particular the seat textile or the knitwear 11, both an upright sitting position and an easily positioned position the human body is made possible without an adjustment of the backrest 28 is performed. The kinked training in the backrest 28 also serves to create a larger space for the subsequent passenger in the row and so avert the rear edge of the seat 1 of this further. In addition, an optimized arrangement and starting position for the display element 22 is also created.

The selected and illustrated seat position in FIG. 4 schematically shows the course of the base frame 6 or of the stringing support frame 19 by way of example for the upright posture of the user. The fabric 10 is further adapted by the load of the user to his body contour 32, as this is also shown simplified. This deformation of the fabric 10 is possible by the inherent elastic properties. As already described above, it is advantageous if the fabric 10 is formed from the fabric 11, wherein the fabric 10 may also be referred to as a seat fabric, which can be manufactured as knitwear, for example on a flat knitting machine.

In this case, the fabric 10 forming knit fabric 11 is a so-called one-piece knit fabric 11, which forms both the seating area 13, the back region 12 and the shoulder and head area 29, 30 continuously or continuously. As a self-supporting construction, the fabric 11 is attached to the base frame 6 optionally with the interposition of Besspannungsstragrahmens 19 and biased. The angle 14 between the seating area 13 and the back area 12 is here chosen to be significantly larger than in conventional seats, in the position in which the backrest 28 for upright sitting in the so-called "upright position". located. The flexibility of the knitted fabric 11 allows both a straight, upright sitting as well as an approximate lying position (recline). However, an adjustment of the angle 16 between the base frame 6 and the vertical 15 is not required and is made possible by the elastic behavior of the knitted fabric 11. By various subsequently described in more detail zones 33 to 38 in the knitted fabric 11, which have mutually different properties, such as elasticities, mesh sizes, number of stitches, etc., the seating comfort is realized or adapted. Preferably, the individual zones 33 to 38 are arranged or formed in the knitting direction symmetrically to the center of the fabric.

In the area of the main seat load - namely the seat area 17 - is the strong elastic zone 35 to ensure the sinking of the user in the fabric. Other zones 33, 34 with less elasticity in the lumbar and thoracic spine support the back of the user and also allow a certain sinking in the fabric 10 in the region of the backrest 28. Due to the selected mesh structure is an optimal adjustment of the seat and / or Backrest contour to the shape of the body of a user in the different positions of use. In the edge region, the knitted fabric 11 is preferably designed as a double-layered tube and thus makes it possible to receive a welting in a known manner. A correspondingly arranged in Besspannungsstragrahmen 19 and / or base frame 6 Kedernut takes on the piping with the fabric 11 and ensures during normal use an optimal permanent connection between this and the fabric 11. Preferably, the knit 11 is compared to the geometric outer dimensions of the Covering support frame 19 10/36 Austrian Patent Office AT505 212B1 2010-11-15 and / or base frame 6 produced in variable ratio smaller. This difference in size of the Besspannungsstragrahmen 19 or base frame 6 and knitted fabric 11 thus causes the required bias in the unused position of the fabric 10. This bias can in the knitting direction -also act in the direction of longitudinal edges 41 and / or transverse to the fabric longitudinal extent.

In a bias in both directions, a very firm support of the knitted fabric 11 on the base frame 6 and / or Besspannungsstragrahmen 19 is achieved.

The material used to form the fabric 11 described hereinbelow is so-called high tenacity polyester (PES) multifilament yarn with flame retardant finish. In the elastic areas or zones rubber thread (also flame retardant equipped) added or individual PES threads replaced by rubber thread. For the uniform color appearance of the knitted fabric 11, it is possible to wrap the rubber thread with the appropriate PES thread. For example, high-strength polyester (PES) and / or Lycra can be used as the thread material for the knitted fabric 11. The used threads of Lycra can be wound with the corresponding PES thread for color adjustment. All materials used meet the ÖKO-Tex Standard 100 and are additionally flame-retardant. The high-tenacity polyester (PES) thread can have the specification 167 dtex f36 / 1 and is sold under the trade name "Trevira CS " distributed. The other thread of the material Lycra has the specification 475 dtex with the trade name "Ultraelastic". on.

5, the fabric 10 is shown in simplified form from the fabric 11 with different zones 33 to 36 in an extended, planar position.

Seen in the longitudinal extent of the clothing 10, the head region 30 and, subsequently, the shoulder region 29 are shown here in the illustration above. These form the first zone 33 for the head, neck and upper back. Subsequent to the first zone 33, the second zone 34 is arranged or formed for the lower back. Subsequently, the seating area 13 is arranged with the third zone 35, which serves to support the buttocks area 17 and thigh area 18. Finally, the fabric 11 of the fabric ends 10 in the fourth zone 36, which forms a thigh support in the region of the popliteal fossa. By different hatching the individual zones 33 to 36 are better to distinguish from each other. The geometric arrangement and design of the zones 33 to 36 is chosen here as an example for a wealth of possibilities, it being advantageous if the individual zones 33 to 36 overlap or overlap in the longitudinal edge region 41 of the fabric 10, as here, for example between Zones 33 and 34 and 34 and 35 is shown. In this case, a mostly strip-shaped edge portion 42 overlaps; 43 of the respective upstream zone 33; 34 at least the central region of the immediately following zone 34; 35. The overarching or overlapping edge portion 42 extends here in the longitudinal extent of the fabric 10 seen up to the dividing line between the first zone 33 subsequent second and third zone 34, 35 zoom. The second zone 34 with its edge portion 43 also engages over this subsequent zone 35 with a similar longitudinal extension, as has been previously described for the edge portion 42 of the first zone 33 and extends here approximately into the central region of the third zone 35. Transitions between the strip-shaped edge portions 42, 43 and the transverse thereto respective end of the zone are preferably arcuately rounded. But it would also be an angular or sharp-edged transition possible. Likewise, the arrangement of a bevel as transition would be conceivable.

In addition, however, it is also possible that further zones 37 and / or 38 can be arranged or provided between the individual zones 33 to. For example, the fifth zone 37 is arranged between the first zone 33 and the second zone 34 and forms a so-called transition zone. This zone 37 extends transversely to the longitudinal direction seen only over the central region and ends before the longitudinal edge regions 41. A sixth zone 38 is here between the second zone 34 and the third zone 11/36 Austrian Patent Office AT505 212B1 2010-11-15 35 arranged or trained. As a result of this additional arrangement of the further zones 37 and / or 38, the supporting or sinking behavior of the covering 10 can be adapted even more individually to the most varied conditions of use. Likewise, noticeable transitions between the heavily loaded zones 33, 34; 34, 35 even better balanced or the transitions between the zones are finely tuned to each other.

The fabric 10 forming the seat fabric is in its functionality u.a. responsible for the comfort, the breathability, the ventilation, the absorption of the body mass as well as the support of the seated or lying body. For optimal adaptation of the fabric 10 to the different body contours of users and to optimally ensure their sitting position, the previously described, different different zones 33 to 38 are provided, which have mutually different properties with respect to elasticity, elongation behavior, etc. It should be noted that it is also possible to use or use both more and less than the previously described zones 33-38. Likewise, the spatial design and arrangement of each other is shown only by way of example for a wealth of possibilities.

With the aid of the above-described flat knitting technique for producing the knitted fabric 11, mass goods having locally different properties can be produced in terms of force and / or elongation behavior. The individual zones 33 to 36 described above for the exemplary embodiment shown in FIG. 5 will be described in more detail below.

The description for the production of the knitted fabric 11 refers to a flat knitting machine of fineness E9 (which means nine needles per inch) with a knitting width of preferably more than 200 needles, depending on the knitting width to be produced. In the region of the zone 36, ie the knee area, the knitted fabric 11 is manufactured in a reduced width of preferably less than 200 needles and usually even decreasing. In principle, the knitted fabric 11 is produced in a single-bed knitting manner, but the tubular edge described above is produced with a second needle bed. The different properties in the individual zones 33 to 36 or 37 and 38 can be realized above all by the type and number of thread materials used, by different mesh sizes and different number of stitches per knitted unit. Hereinafter, a possible embodiment will be described for each of the zones 33 to 36 shown here.

In the zone 33, only PES is used as the thread material. The bias of the entire knitted fabric 11 is achieved by the smaller width of the fabric 10 or the textile compared to the width of the base frame 6 or Besspannungsstragrahmens 19. In the transition region from the first zone 33 to the second zone 34, a dynamic progression is implemented by systematically increasing mesh sizes. The support surface under the headrest 21 and the shoulder in an oblique or resting posture, however, is made with a smaller mesh length. This achieves a lower elastic and thus firmer and tighter covering. Possible characteristics for the first zone 33 are:

Material PES 167dtexf36 / 1 8 threads per color Mesh resistance 11.8 / 12.0 fabric removal 10 zone length approx. 270 knitting rows Zone width 200 needles Strip tensile test according to DINEN 13934-1 Fmax > 1080 N, and S < 95% In this strip tensile test, an unstretched knitting width of 50 mm was tested at a chuck length of 200 mm, and until fracture at Fmax > 1080 N stretched. The strength in the strip tensile test according to DIN EN 13934-1 should be for this zone of the knitted fabric 11 in a lower limit of 700 N and an upper limit of 1400 N. The smaller the specified value for the stitch strength, the firmer and firmer the knit 11 becomes. With a larger value, the knit 11 becomes softer and more elastic.

Due to the necessary or required sinking depth of the user in the seat 1, the greatest elasticity of the knitted fabric 11 is necessary in the second zone 34. This can be seen simplified from the illustration of FIG. 4. The thread material used here is exclusively the lycra thread preferably spun with PES. By way of the number of individual threads used and the mesh size or mesh size, these elastic properties within the zone 34 can be influenced in a targeted manner. Possible characteristics for the second zone 34 are:

Material Lycra (wound with PES) 2 threads first color 1 thread second color PES 167dtexf36 / 1 8 threads per color Stitch resistance 11.2 / 11.4 11.8 / 12.0 fabric removal 10 10 zone length approx. 115 knitting lines approx. 115 knitting lines zone width 126- 170 needles 15-37 Needles Elasticity according to DIN EN Fmax «22 N, 14704-1 at S = 100% Strip tensile test according to DIN EN 13934-1 Fmax > 1080 N, and S < 95% In this strip tensile test a knit width was tested in the unloaded state of 50 mm with a clamping length of 200 mm and stretched to twice the length of 400 mm. The force required for this is about 22 N. A lower limit or a lower range of the tensile force is usually 10 N and an upper limit or an upper range 40 N for the extension of the sample strip by 100%.

The third zone 35 shown in FIG. 5 forms the seating area 13 and thus the seat surface of the seat 1. This seat should give the impression of an entire, self-contained, continuous surface, which is formed by the fabric 11. Here can be used as thread material also PES. To get a "tilt" To enable the entire zone 35, on the left and right longitudinal edge portion 41 shown in FIG. 5 additionally strongly elastic areas are provided, which are designated in FIG. 5 by the reference numeral 43 for the edge portions. These can be seen in the direction of the longitudinal extension of the knitted fabric 11, arbitrarily wide and optionally formed with different widths. The edge portions 43 may have a wedge-shaped longitudinal course. These thus ensure a seat surface alignment of the seat contour or body contour 32 corresponding to an angle 48 -see Fig. 4 - with respect to the base frame 6 or Besspannungsstragrahmen 19 in the seat area, in particular the seating area 13. This angle 48 can be from an angular range with a lower limit of the fifth °, in particular 10 °, preferably 15 ° and an upper limit of 45 °, in particular 35 °, preferably 20 ° can be selected. Possible characteristic values for the third zone 35 are:

Material PES 167dtexf36 / 1 8 threads per color spun elastane 2 threads per color stitch strength 12.4 / 12.6 12.6 / 12.4 fabric removal 10 10 zone length approx. 240 rows of knitting approx. 220 knitting rows zone width 126- 170 needles each 15 -37 needles Strip test according to DIN EN 13934- 1 Fmax > 1170 N, and S < 96% -

In this strip tensile test, a knit width was tested in the unloaded state of 50 mm with a clamping length of 200 mm and until fracture at Fmax > 1170 N 13/36 Austrian Patent Office AT505 212 B1 2010-11-15 stretched. The zone 35, which forms the seating area 13, in particular the seating area, should have a strength in the strip tension test according to DIN EN 13934-1 in a lower limit of 800 N and an upper limit of 1500 N.

The details from the first column relate to the zone 35 shown in FIG. 5. The further details according to the second column relate to the two edge sections 43 formed in the longitudinal edge regions.

Finally, with the fourth zone 36, the seating area 13 or the seat surface of the seat 1 in the direction of the knee area of the user is delimited therefrom. This zone 36 is intended to prevent it from slipping out of the seat 1 along the longitudinal course of the base frame 6 or stringing support frame 19 out of the seating area 13. The fourth zone 36 has a very high bias in the transverse direction of the knitted fabric 11, which is also achieved by an additional reduction of the knitting width of the knitted fabric 11 in the untensioned starting position. In this zone 36 is used exclusively as thread material PES. Possible characteristics for the fourth zone 36 are:

Material PES 167dtexf36 / 1 8 threads per color Stitch resistance 11.7 / 11.7 fabric removal 10 zone length approx. 90 knitting rows zone width approx. 192 needles (preferably decreasing) maximum strength, since the fabric here is double-layered To increase the strength of the fourth zone 36 Here, the fabric 11 formed two layers, creating a kind of threshold or wall against slipping out for the user.

These values given above relate to a knit size in the unfolded state and stretched position in the longitudinal direction of the knit of about 500 mm wide and about 1200 mm in length.

In FIGS. 6 and 7, a schematic binding view of individual threads 44 to 47 and a binding-technical representation for a possible embodiment of the knitted fabric 11 are shown in simplified form. All zone transitions and demarcations are designed dynamically by correspondingly adapted mesh sizes. In the edge region of the entire knitted fabric 11, a hose is knitted circumferentially, which serves to receive a fastening means. This is preferably formed by a flat piping or a flat piping profile. The attachment means in connection with the knit 11 thus forms the interface or the holder between the base frame 6 and Besspannungsstragrahmens 19 and the fabric 10. In addition, it is possible in the area between the piping hose and the seat or Rückenlehnengestrick this in the field additional frame contact additionally knitting technology to reinforce to prevent any damage.

In FIGS. 6 and 7, the threads 44 to 47 are shown to form the knit 11. It should be noted that the knitting and thread course of the individual threads 44 to 47 has been selected only as an example for a variety of possible knitting designs and the knit design can be adapted to a variety of conditions of use and varied. Likewise, the binding of the individual threads 44 to 47 with each other by other than the thread courses shown here is possible.

8 to 10 a possible embodiment of the lining element 7 for the back 5 of the seat 1 is shown, again in order to avoid unnecessary repetition, referred to the detailed description in the preceding Figs. 1 to 7 or Reference is made. Likewise, the same reference numerals and component designations as in the preceding Figs. 1 to 7 are used for the same parts. [00109] The lining element 7 shown here is preferably connected to the support frame 2 (not illustrated here) to form an assembly and forms a receiving or supporting unit for the base frame 6 or stringing support frame 19 and other previously described components. Preferably, the cladding element 7 is formed as a self-supporting, inherently rigid construction, in which case the most diverse shaping methods and materials can be used. The material used can be selected from the group of plastics, laminated and / or fiber-reinforced plastics, for example with glass fibers, carbon fibers, metals, in particular light metals, etc. Likewise, however, any combination of different materials is possible. But it can also be mats, braids, knitted or woven fabric embedded in the plastic or even integrally formed on this. The cladding element 7 can be manufactured by a wide variety of manufacturing processes, wherein the preferably shell-like structure formed thereby also serves to transfer the load from the user to the support frame 2. Furthermore, the shape of the cladding element 7 also serves to set the free space between seats 1 arranged immediately one behind the other. Otherwise, an unwanted body contact between the users of seats 1 arranged behind one another could take place through the seat support formed from the knitted fabric 11. Likewise, however, the cladding element 7 is also used as a supporting structure or for receiving the armrests 20, the headrest 21, the one or more display elements 22, the table 23 and the receiving and holding element 24, 25.

The fact that between the two previously described seating positions no adjustment of the base frame 6, in particular the backrest 28, to perform in relation to the vertical 15 for the change of the desired seating position, can here with the least effort the inclusion of the base frame 6 and / or Besspannungsstragrahmens 19 done in the cladding element 7. On a receiving side 49 of the cladding element 7 7 support elements 50 are arranged on the user side 4 in the side edge region of the shell-like cladding element. The one or more support members 50 serve to support the previously described and later described in more detail base frame 6 for the load transfer. In this embodiment variant shown here already serves the base frame 6 for holding the fabric 10 and is required, releasably on the cladding element 7, in particular on the support member 50, supported. This makes it possible for cleaning personnel or service personnel in a simple manner, remove soiled or damaged clothing 10 together with the base frame 6 from the cladding element 7 and a new, pre-assembled fabric 10 together with the base frame 6 back into the cladding element 7 to complete the seat 1 insert.

In the area of the cladding element 7 shown above, a receptacle or holder of the head bag 21, which will be described in more detail later, is also provided. In the centrally extending recess 17 on the back 5 of the cladding element 7 different coupling devices for holding the display element 21, the table 22 and the receiving and holding element 24, 25 are provided.

An inner surface 51 of the cladding element 7 is arranged in the region of the receiving side 49 by a gap spaced from the fabric 10, as shown in simplified form in FIG. 10. This space between the fabric 10 and the inner surface 51 of the cladding element 7 serves to receive the body of the user, as shown by the body contour 32 in FIG. 4 is simplified.

Furthermore, this gap also serves to absorb radiated heat of the user, which can be simply radiated through the knitted fabric 11 in this or dispensed and from there optionally also additionally derived. The fact that the fabric 10 is formed from the fabric 11, this not only optimally supports the body of the user, but also allows a sufficient heat and moisture removal and associated good ventilation of the entire seat. 1

The fact that the covering 10 formed from the knitted fabric 11 is selected as the seat support instead of the usual seat cushions made of a wide variety of foamed plastics which are supported on a support structure, [00114] FIG. This gap between the fabric 10 and the inner surface 51 is provided. In order to allow for a comfortable sitting comfort even for heavier persons and to avoid the risk of touching the person on the inner surface 51 of the cladding element 7, it is possible to provide an intermediate layer 52 on the inner surface 51 of the cladding element 7. This intermediate layer 52 may be formed of a plastic foam on which comes after appropriate deformation of the fabric 10 by the user of this there to the plant. For a direct hard resting on the cladding element 7 is prevented. This intermediate layer 52 can be adapted in its properties to a wide variety of operating conditions. In any case, make sure that the foamed plastic used is preferably flame-retardant. This flame retardancy can be done by a variety of additives or admixtures in the foam scaffold in a known manner. Also, an impregnation or coating with flame retardant materials and optionally a coating with a flame-retardant coated envelope is possible.

Regardless, it would also be possible to provide at predefined positions of the seat 1 within the cladding element 7 one or more support straps 53 which are arranged transversely to the longitudinal extent of the seat 1 and the longitudinal edge portions 41 within the cladding element 7 extending , This support belt 53 preferably has a lower elasticity than the fabric 10, and serves to prevent excessive deformation of the fabric 10 by the user in the highly loaded areas of the seat 1, a contact with the cladding element 7, in particular the inner surface 51 , Thus, during use, first the fabric 10 is deformed or stretched so far that a concern of the body contour 32 on the support belt 53 takes place and this subsequently acts to support the load of the user's body supporting the fabric 10. For this purpose, the support belt 53 is to be formed in the direction of its longitudinal extent with a preferably lower elasticity with respect to the fabric 10. A combination of the support belt 53 with the intermediate layer 52 is also possible.

One of these support straps 53 may also be arranged at the end of the thigh area 18 towards the hollow of the knees below the covering 10 on the base frame 6 and / or the stringing support frame 19. This serves to make it difficult or prevent the user slipping out of the seat 1 during use. Thus, in the fourth zone 36, the already tight knit fabric 11 additionally reinforced.

10, a light source 54 arranged on or attached thereto is shown in simplified form in the region of the support element 50 arranged on the cladding element 7. This light source 54 may be arranged for better protection and the holder, for example, in a groove-shaped recess 55 of the support member 50. For this purpose, the luminous means 54 may be arranged adjacent to the base frame 6 and within its boundary. Furthermore, the luminous means 54 may be formed, for example, by a plurality of individual points of light or else by a fiber-optic line emitting continuously and emitting visible light. Due to the fact that the knitted fabric 11 is formed by a multiplicity of stitches, the transmitted light of the lighting means 54 will in any case be transmitted through. These light sources 54 may extend along the longitudinal edge region 41 or be arranged there. However, a transverse arrangement in the area of the headrests 21 and / or the knee area is also possible. These bulbs 54 can be used, for example, to make the user's seat 1 easier to recognize when the passenger cabin is darkened. If, for example, a fiber optic cable is used as the luminous means 54, this can be designed such that it emits or radiates the light on its outer surface. The feeding of the light can be effected by means of a supply unit not shown here, which can be arranged or provided in the region of the support frame 2.

FIG. 11 shows a possible embodiment of the base frame 6 for forming the seat 1. As already described above, the covering 10 16/36 Austrian Patent Office AT505 212 B1 2010-11-15 can be stretched on this base frame 6. Preferably, the base frame 6 is formed of a light metal or a high-strength plastic material which has sufficient strengths to ensure a load transfer with sufficient stability. The section of the base frame 6 forming the backrest 28 here has a uniform width 56 over its entire longitudinal course. As a result, the design of the cladding element 7 is simplified and avoided in directly juxtaposed seats 1 disturbing open spaces. The width 56 corresponds to the usual seat dimensions or minimum dimensions for the particular application.

As already described above, the front seat portion 57 of the seat portion 13 is designed to shorten the seat adjustable. In order to be able to carry out this adjustment, a joint arrangement 58 is provided on both sides of the seat region 13 of the base frame 6. With this it is possible to pivot a frame part 59 from its use position to its standby position. By this folding down a lengthened shortening of the seating area 13 takes place, but it is always possible to take even on this remaining space. The folded position is shown in dotted lines.

In order to enable a pivoting of the pivotable frame part 59 within the cladding element 7, this has a relation to the width 56 of the rest of the base frame 6 to smaller width 60. The representation of the folded seat portion in the so-called ready position has already been shown and described previously in FIG. The folded-up position and thus the use position of the seat 1 has been shown and described in FIG.

To avoid that the user must knowingly initiate an actuation process to perform the adjustment of the upper seat portion 57, this should be automated and automatic. For this purpose, the introduced by the user in the seating area 13 weight should represent the time at which the adjustment and thus the folding up of the front seat portion 57 in the use position. Thus, if the user takes place at the seat 1, the clothing 10 is deformed. This seating or sitting down is registered by a detection device 61, shown in simplified form in the seating area 13. This detection device 61 may be formed by a sensor system, for example by mechanical or electronic means. The detection device 61 is further connected to a likewise simplified illustrated adjusting device 62 in line connection, which in turn is in communication with the pivotable or adjustable front seat portion 57. It should be noted that the illustrated detection device 61 and adjusting device 62 are shown only schematically simplified and can be formed by any known from the prior art devices or devices. The detection device 61 and the actuating device 62 operatively connected therewith form an actuating device 63 for the seat section 57.

As components for forming the adjusting device 62, for example, a variety of cylinders, stepper motors, electric, pneumatic or hydraulic actuators, etc. can be used. The operative connection between the detection device 61 and the adjusting device 62 can also be done by a variety of media, such as mechanical, electrical, pneumatic, hydraulic, etc.

If the detection device 61 has now registered the seating of a user on the seat 1, the adjusting device 62 is activated, which carries out the pivoting movement of the seat section 57 from the folded-down position into the normal position of use. By this pivoting is an extension of the seating area 13, whereby an even better support of the thigh area is done to the popliteal area for the seated on the seat 1 user.

The user leaves the seat 1 and rises from this, this is also registered by the detection device 61 and it automatically takes place the reduction of the seat surface of the seat portion 13, whereby a larger space for leaving the seat 1 and the formed thereof Seat row is possible. FIG. 12 shows a further possible embodiment of the seat 1, which is possibly independent of itself, in particular the mounting of the covering 10 on the covering element 7. To avoid unnecessary repetition, reference is made to the detailed description in the preceding figures. Likewise, the same reference numerals and component designations as in the preceding Figs. 1 to 11 are used for the same components.

The partial region of the seat 1 shown in FIG. 12 corresponds in its view to that representation according to FIG. 10 described in detail above. In contrast, the arrangement of the support element 50 for mounting the base frame 6 is dispensed with here.

In this embodiment shown here, the base frame 6 is connected to the Verklei-training element 7 to the support unit 8, whereby a sufficient inherent rigidity of this assembly can be achieved. The support unit 8, in particular the cladding element 7, in turn, is connected to the support frame 2 (not illustrated here) for forming the seat 1.

The fabric 10 is clamped on the Besspannungsstragrahmen 19. This in turn creates the possibility to remove the cover 10 together with the Besspannungsstragrahmen 19 of the support unit 8 for the purpose of cleaning or replacement of the support unit 8 in a simple manner and reassemble. Thus, in turn, the cleaning or service personnel quickly perform a change of the fabric 10, wherein the cleaning or the change of the fabric 10 takes place at a location remote from the seat 1 own location. The Besspannungsstragrahmen 19 again has correspondingly formed holding devices for the attachment of the fabric 10. Since in this embodiment, the Besspannungsstragrahmen 19 is supported in its installed position on the base frame 6 of the support unit 8, this can be performed in its stability and dimension less than the base frame 6.

In order to easily fasten the stringing support frame 19 to the base frame 6 and hold it there, it is advantageous if the base frame 6 has a recess 64 on the side facing the side wall of the lining member 7, in which the stringing support frame 19 is inserted from the user side can be. On the presentation of their own fasteners between the base frame 6 and the Besspannungsstragrahmen 19 has been omitted for the sake of clarity.

Furthermore, it is shown in simplified form here that in the base frame 6, in turn, illuminants 54 can be arranged or provided, which are arranged in the depression 55. In order to avoid contact or contact of the luminous means 54 with a user in the position located on the seat 1, the luminous means 54 or its receptacle is arranged at a distance from the fabric 10 in the direction of the inner surface 51 of the cladding element 7.

In order to allow for the additionally arranged support belt 53, a change in the support force generated by him, this is still a simplistic Versteilvorrich shown device 65 in the region of the base frame 6 and Verkleidungselements 7 assigned. This adjusting device 65 may be provided, for example, only at one end of the support belt 53 or at both ends thereof. On the representation of the operation of the adjusting device 65 has been omitted for the sake of clarity, and this is freely selectable according to the known prior art.

The arrangement of the adjusting device 65, it is possible to change the distance between the support belt 53 in the unloaded position with respect to the fabric 10. If the distance is reduced, that path is reduced, which the fabric 10 can be deformed by the use of the support belt 53 before the support belt 53 takes over the further supporting effect. The shorter this deformation, the faster the support belt 53 comes into action, whereby the support behavior of the seat 1 can be adapted individually to the user. The shorter the way and tighter the support belt is trained, the firmer and harder the seat feeling.

13 and 14, the headrest 21 is shown for the seat 1, which may optionally represent an independent solution according to the invention. For the same parts, the same reference numerals or component designations are used here as in the preceding FIGS. 1 to 12. Likewise, to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1-12.

The headrest 21 is arranged in the upper region of the cladding element 7 or the support unit 8 and is preferably detachably connected to the cladding element 7. The headrest 21 has in this embodiment shown here, a central part 66 and both sides thereof arranged thereon and connected thereto side parts 67, 68. A pad shown in simplified form is preferably arranged on the side facing the user for supporting the head. The two side parts 67, 68 are pivotally mounted by hinge arrangements 72, 73 in each case in the normal use position in approximately vertically aligned pivot axes 70, 71 according to arrows. This makes it possible for a user of this headrest 21 to pivot the two side parts 67, 68 laterally of the central part 66 toward the head of the user, so as to achieve a cup-shaped support. As a result, the temporal area of the head can be comfortably supported on the headrest 21 in the rest position.

The padding 69 of the headrest 21 is supported on preferably flat-shaped support elements 74 to 76. These support elements 74 to 76 form the backbone of the headrest. The two joint arrangement 72, 73 for the pivotable mounting of the two side part 67, 68 are thus arranged between the support elements 74 and 75 or 74 and 76 and may be formed like a hinge. On the one hand to achieve sufficient stability for the support of the pivoted side parts 67, 68 and on the other hand to still allow a pivoting movement relative to the central part 66, the two hinge assemblies 72, 73 to vote accordingly.

To adjust the entire headrest 21 here the support member 74 of the central part 66 is assigned a support assembly 77 on the side facing away from the user. This support assembly 77 serves to connect the headrest 21 with the cladding element 7 and / or the base frame 6 and / or the support element 50. For this purpose, the support assembly 77 comprises at least one coupling element 78, which is connected to one of the components of the seat 1 and held thereon. Between the coupling element 78 and the support assembly 77, a further hinge assembly 79 is provided, with which the support assembly 77 and subsequently the central part 66 with the side parts 67, 68 disposed thereon with respect to the vertical 15 is pivotable. The hinge arrangement 79 has a pivot axis 80, which is preferably aligned horizontally, ie parallel to the contact surface 3, as well as parallel to the supporting surface 9 formed by the covering 10. By the pivot axis 80 of the hinge assembly 79, a further additional alignment and adjustment of the entire headrest 21 can be made to the wishes of the user. Preferably, the further pivot axis 80 is arranged directly adjacent or also the support surface 9 formed by the covering 10 upstream. It is thereby achieved that the portion of the headrest 21 facing the seating area 13 can be pivoted into the clothing 10. As a result, a smooth transition from the loaded clothing 10 toward the headrest 21 is achieved.

In order to adjust the headrest 21 to different sizes of users, here at least one, but preferably a plurality of guide assemblies 81 is further provided between the support assembly 77 and the support member 74 of the central part 66. These guide arrangements 81 allow the entire adjustment of the headrest 21 in the longitudinal direction or longitudinal extent of the backrest 28. By this adjustment, it is possible to change the distance between the support on the headrest 21 and the support surface 9 in the seating area 13. The guide arrangement 81 can be formed as a longitudinal guide and is preferably arranged in each case at edge regions of the central part 66, which are immediately adjacent 19/36 Austrian Patent Office AT505 212 B1 2010-11-15 the side parts 67, 68 assigned.

Furthermore, it is still possible that in the region of the side parts 67, 68 and / or the central part 66 further additional components or components, such as speakers, light applications, etc. may be arranged or provided. These can be installed optionally depending on the required seat equipment and the associated seat comfort of the seat 1.

FIGS. 15 and 16 show an optionally independent embodiment of the table 23, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 14. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 14 or referenced.

The table 23 has a position facing the user in the position of use and provided for parking various objects table surface 82. In order to pivot the table 23 between the use position in the approximately horizontal position and that, folded in the recess 27 position, a corresponding hinge assembly is provided.

On the side facing away from the table surface 82 side of the table 23, a receiving tray 83 is additionally provided. As can be seen in the folded-up position of the table 23 shown in FIG. 16, the user of the subsequent seat faces away from the table surface 82 of the table 23 and faces the receiving compartment 83. An end face 84 of the table 23 facing the user in the use position has a rounding or a grip recess formed by it for easier actuation and stiffening of the table surface 82. The receiving compartment 83 is bounded by a compartment wall 85 at the side remote from the table surface 82. In order to avoid in the position of use, ie the folded-down position of the table 23 a Fierausfallen of introduced in the receiving tray 83 items, the compartment wall 85 is aligned at an angle to the table surface 82 extending. An angle 86 between the table surface 82 and the compartment wall 85 is tapered toward toward the end face 84. By this convergence of the compartment wall 85 with respect to the table surface 82 a Flerausfallen is avoided by stored in the receiving tray 83 items during the folded position of the table 23. Characterized in that the entire support unit 8 is formed in its position fixed with respect to the footprint 3, the orientation of the table surface 82 relative to the vertical 15 can be made approximately horizontally. Preferably, the table surface 82 is aligned parallel to the footprint 3 in its position of use. In this case, then the compartment wall 85 is inclined with respect to the footprint 3 toward the back 5 of the seat 1.

Coming back to the illustration in FIGS. 1 to 3, it should also be pointed out that it is possible in the region of the rear side 5 of the seat 1 in the region of the receiving element 24 and / or the flanging element 25 to likewise provide an illumination means 87 here. to arrange. In this case, the illumination means 87 may be arranged or designed such that, when the passenger cabin is darkened, an illumination of the free space arranged below the seat 1 takes place. The supply unit for this illumination means 87 can in turn be arranged or provided in the region of the support frame 2.

Furthermore, it is also possible to carry out the receiving element 24 and the holding element 25 in one piece, wherein the longitudinal extent for receiving the objects preferably extends over the entire width 56 of the seat 1. This combination of receiving element 24 and the flap element 25 may also be formed from a knit and connected to the cladding element 7 accordingly.

For the sake of order, it should finally be pointed out that in order to better understand the structure of the seat 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size. 20/36 Austrian Patent Office AT505 212 B1 2010-11-15
