Description

本発明は、特許請求項１の前文に記載の車両シートに関する。 The present invention relates to a vehicle seat according to the preamble of claim 1.

自動車の車両シートは、クッション要素及び各バネシステムによって予め定められたシート形状が設けられた、少なくとも１つのシートクッションとシートバックとを備える。この種の車両シートとして構築された物は、従来、クッションパッドにより、次いでこれに対応するシートカバーにより覆われた各バネ下設備を具備する。この場合、詰め物及びシートカバーの綴じた継目により、自動車の運転者のために、長い間座っている場合にも疲労の症状をできる限り少なくし、かつ運転者の特定の身体構造にできる限りうまく適応されたシート形状を設けるようにされる。このため、車両シートに、コントローラを介してかつ圧力発生装置により、シート形状を特定の運転者に最適な形で適応できるようにした、１つ以上の空気圧要素を設けることが知られている。これらの比較的大きい空気圧要素の欠点は、シート形状に対する作用が、背もたれ、及びシートクッションの、それぞれ、比較的厚肉のクッションパッドのために制限されることである。   The vehicle seat of an automobile comprises at least one seat cushion and a seat back provided with a seat shape predetermined by the cushion element and each spring system. Objects constructed as this type of vehicle seat conventionally comprise unsprung equipment covered by a cushion pad and then by a corresponding seat cover. In this case, the stitched seam of the stuffing and seat cover will reduce the symptoms of fatigue as much as possible when sitting for a long time for the driver of the car and as best as possible for the specific body structure of the driver. An adapted sheet shape is provided. For this reason, it is known to provide a vehicle seat with one or more pneumatic elements that allow the seat shape to be adapted to the particular driver in an optimal manner via a controller and by means of a pressure generator. The disadvantage of these relatively large pneumatic elements is that the action on the seat shape is limited due to the relatively thick cushion pads of the backrest and seat cushion, respectively.

さらに、車両シートの場合、特にトラックの車両シートの場合には、シート内に空気圧要素を設けることが知られており、この要素を制御装置を介して加圧し、空気圧要素を介して種々なマッサージ機能を実現することができる。このような手段により、小さな粒から構成された車両シートのマッサージパッドと同様の方法で、周期的に変化するシート形状が作られ、車両シートに長時間座っていることからくる疲労の症状を一定の方法で防止することができる。この場合の欠点は、空気圧要素が、一般に、空気圧で、したがって圧力に関連した方法で相互に接続されるので、小さな効果しか発揮しないこと、及び／又は車両シートのクッションパッドの下で、大きい又はやや大きい圧力が発生した場合にも、また一般にこのクッションパッドの上の固定位置に綴じられたカバーのために、マッサージ効果が比較的弱く、運転者の身体に対する圧力の効果的な伝達が回避されることである。特許文献１に、車両シート内のシート形状の表面に対して小さい、複数のクッション状のエアクッションの統合が既に開示されており、このエアクッションは、シート形状に作用を及ぼすためのコントローラにより一定の方法で加圧できるものであり、この結果、異なるマッサージ効果が得られる。この場合、シートクッション及びシートバック内のエアクッションの正確な配置については説明されていない。特許文献２にも、同様に、数多くの小さいエアクッションがクッション内に埋め込まれ、かつシート形状を変えるために、それぞれ別個のラインを介して作動できる車両シートが開示されている。最後に、特許文献３及び特許文献４にも、同様に、小さいエアクッションがクッション内に配置された車両シートが開示されている。 Furthermore, in the case of vehicle seats, in particular in the case of truck vehicle seats, it is known to provide a pneumatic element in the seat, which is pressurized via a control device and various massages via the pneumatic element. Function can be realized. By such means, a seat shape that changes periodically is created in the same way as a massage pad for a vehicle seat composed of small particles, and the symptoms of fatigue caused by sitting on the vehicle seat for a long time are constant. Can be prevented by this method. The disadvantage here is that the pneumatic elements are generally connected with each other in a pneumatic and thus pressure-related manner, so that they have a small effect and / or are large or under the cushion pad of the vehicle seat. The cover is bound to a fixed position on the cushion pad in the event of a slightly high pressure, and the massage effect is relatively weak, avoiding effective transmission of pressure to the driver's body. Is Rukoto. Patent Document 1 has already disclosed the integration of a plurality of cushion-shaped air cushions that are small with respect to the seat-shaped surface in the vehicle seat, and this air cushion is fixed by a controller for acting on the seat shape. As a result, a different massage effect can be obtained. In this case, the exact arrangement of the seat cushion and the air cushion in the seat back is not described. Similarly, Patent Document 2 discloses a vehicle seat in which a large number of small air cushions are embedded in the cushion and can be operated via separate lines in order to change the seat shape. Finally, Patent Document 3 and Patent Document 4 similarly disclose a vehicle seat in which a small air cushion is arranged in the cushion.

これに対して、本発明は、加圧要素が、所望のシート形状についてできる限り効果的にシート内に配置された、冒頭で説明した種類の車両シートを提供するという目的を有するものである。In contrast, the present invention has the object of providing a vehicle seat of the type described at the outset, in which the pressure elements are arranged in the seat as effectively as possible for the desired seat shape.

本発明の目的は、請求項１の特徴を有する車両シートによって達成される。本発明の好ましい発展形態及び改良形態が、従属請求項の主題である。   The object of the invention is achieved by a vehicle seat having the features of claim 1. Preferred developments and improvements of the invention are the subject of the dependent claims.

車両シートは、それぞれ、シート形状に作用を及ぼすための複数の加圧要素が設けられたシートクッション及びシートバックと、これらの要素の一定の加圧のためのコントローラとを備えており、このコントローラにより、異なるマッサージ効果を得ることができる。加圧要素は、シート形状の表面に対して小さく、かつそれぞれ、実質的に点状にシート形状を変えるため、ラインを介して別々に作動できるクッション状の要素である。したがって、まず最初に、実質的に点状に圧力が発生することにより、シート形状が一定の方法で変化できるようになるので、効果的なマッサージ機能が加圧要素によって実現できる。加圧要素が比較的小さいクッション状の要素であることにより、必要な体積が小さく、したがって反応時間が短い。小さい追加空間容積が必要となるだけであるので、マッサージ機能を既存シートに適合させることができる。個々の要素に又は複数の加圧要素を組み合わせたものに、点状に圧力が発生するだけで、シート形状を一定に変化させるのに、及びマッサージ機能を効果的に実現させるのに、全く十分である。ほんの小さい体積の加圧要素があるだけであるが、車両のシートバック及びシート内で、点の形で圧力を増加させることにより、ライニング及び／又は詰め物及びカバーを具備したシート形状により、またこのシート形状と合わせて、一定のかつ効果的な方法でシート形状を変えることができる。この場合、加圧要素は、車両シートの詰め物とカバーとの間に配置される。したがって、加圧要素による実質的に点状に圧力を発生させる効果は、さらに増加することができる。この場合、実質的に点状に、とは、個々の加圧要素により別々に動作可能な、シートの又は車両シートのシートバックの表面全体に対して比較的小さい領域、具体的には５〜１０ｃｍ ２ 程度の領域という意味であると理解されたい。特定の要素の数及び配置は、実質的にシート形状の表面全体に分散されることが好ましいが、個々の一定の領域に限定されることもある。 Each vehicle seat includes a seat cushion and a seat back provided with a plurality of pressurizing elements for acting on the seat shape, and a controller for constant pressurization of these elements. Thus, a different massage effect can be obtained. The pressurizing element is a cushion-like element that is small relative to the sheet-shaped surface and can be actuated separately via lines in order to change the sheet shape substantially in the form of dots . Therefore, first, the pressure is generated substantially in the form of dots, so that the sheet shape can be changed in a certain manner, so that an effective massage function can be realized by the pressurizing element. Because the pressure element is a relatively small cushion-like element, the required volume is small and thus the reaction time is short. Since only a small additional space volume is required, the massage function can be adapted to the existing seat. It is quite enough to change the sheet shape constantly and to realize the massage function effectively by simply generating pressure in the form of dots in individual elements or in combination with multiple pressure elements. It is. There is only a small volume of pressure element, but by increasing the pressure in the form of dots in the seat back and seat of the vehicle, the seat shape with the lining and / or stuffing and cover, and this Together with the sheet shape, the sheet shape can be changed in a certain and effective manner. In this case, the pressurizing element is arranged between the filling of the vehicle seat and the cover. Therefore, the effect of generating pressure substantially in the form of dots by the pressurizing element can be further increased. In this case, substantially punctiform means a relatively small area with respect to the entire surface of the seat back of the seat or of the vehicle seat, which can be operated separately by the individual pressurizing elements, in particular 5 to 5 It should be understood that it means an area of about 10 cm 2 . The number and arrangement of specific elements is preferably distributed substantially throughout the sheet-shaped surface, but may be limited to individual, constant areas.

本発明の１つの好ましい改良形態によれば、車両シートの加圧要素及びコントローラにより、所望の固定シート形状が設定できる。この予め設定された固定シート形状、即ち個々の圧力要素の異なる加圧によって定義されたシート形状に基づいて、たとえば胸椎領域などの領域全体の、個々の圧力要素又は複数の加圧要素を周期的に変えることにより、又はたとえばこれらを組み合わせて作動させることにより、簡単かつ効果的な方法で、マッサージ機能が実現できることが好ましく、運転者専用に適応されたシート形状は、後に容易に元に戻る。したがって、複数のユーザのために同様に予め設定されたシート位置は、近頃は時折自動車内で既に実現されているように、一定の方法で、即ち特定の整形外科及び／又は快適性に関連する条件に従って、異なる車両ユーザに車両シートを適応させることができる。本発明によれば、シート形状は、１つ以上のマッサージ動作が行われた後、常に、再び回復されるか又は自動的に元に戻ることができる。このことは、それぞれ、ほんの小さい体積しか有さず、したがって反応時間の短い、個々の要素の加圧によって行われることが好ましい。組み合わせられたマッサージ機能を有する本発明による形状調整は、小さい空間しか占めず、車両シートの個々の要素、特にシートの、バネ下設備、詰め物、及びカバーの間に、簡単に適合させることができる。   According to one preferred refinement of the invention, the desired fixed seat shape can be set by the vehicle seat pressure element and the controller. Based on this preset fixed sheet shape, i.e. the sheet shape defined by the different pressurization of the individual pressure elements, the individual pressure element or the plurality of pressurization elements of the entire region, e.g. It is preferred that the massage function can be realized in a simple and effective manner, for example by changing to or by operating in combination, for example, and the seat shape adapted exclusively for the driver is easily restored later. Thus, the preset seat positions for multiple users as well are related in a certain way, i.e. to certain orthopedics and / or comfort, as has already been realized in automobiles from time to time. According to the conditions, the vehicle seat can be adapted to different vehicle users. According to the invention, the sheet shape can always be restored again or automatically restored after one or more massage operations have been performed. This is preferably done by pressing the individual elements, each having only a small volume and thus a short reaction time. The shape adjustment according to the invention with a combined massage function occupies a small space and can be easily adapted between the individual elements of the vehicle seat, in particular the unsprung equipment, the filling and the cover of the seat. .

本発明の１つの好ましい改良形態によれば、加圧要素は、シート状の支持挿入物に固定され、車両シートのライニングの下に配置され、このライニングは、シートのカバーによって覆われる。このことにより、本発明によるシートの組立てが容易になる。何故なら、個々の要素及びそれらの接続ラインが支持面に固定されて、車両シートの生産中、車両シートがすべったり移動したりすることが回避されるからである。したがって、特定の圧力要素の位置が正確に確立されるので、特に、シート形状の領域内にある個々の場所の一定のマッサージでさえも可能となる。   According to one preferred refinement of the invention, the pressing element is fixed to a seat-like support insert and is arranged under the lining of the vehicle seat, which lining is covered by a seat cover. This facilitates assembly of the seat according to the present invention. This is because the individual elements and their connecting lines are fixed to the support surface to prevent the vehicle seat from sliding or moving during the production of the vehicle seat. Thus, even a constant massage of individual locations within the sheet-shaped region is possible, since the position of a particular pressure element is established accurately.

本発明のさらに好ましい改良形態によれば、加圧要素の形状は、シート形状内に、実質的に点状の圧力領域が作られ得るような形状である。このことにより、１つの要素を動作させることにより、シートクッションの又は背もたれの、又は少なくともその大部分の領域全体が、同様に動くことが回避される。点状に加圧することは、シートによって実現できるマッサージ機能の多様性と同様に、より様々な形でシート形状を予め設定できるという特定の利点を有する。点状に圧力領域を発生させることに実質的に適応される加圧要素の形状は、たとえば、側方に境界の継目を有する楕円形又は円形の形状であるので、要素が加圧された場合には、実質的にシート形状の表面に対して横方向にのみ拡大される。点状に圧力が発生できるような、圧力要素の形状の代替例として、シート状の対向する両側壁によって接続された蛇腹状の側部領域を設けることがある。ここでもまた、実質的にシート面の及び背もたれ面の表面方向に、圧力が発生し、これに関連して要素が両側部に拡張することも、したがって、シート状の（点状でない）圧力が発生することもない。勿論、この代わりに、本発明のこの態様に従って、マッサージ動作に関して、実質的に点状の加圧、即ち一定かつ効果的な加圧、及び所望のシート形状の設定が実現され得る限り、他の任意の形状の加圧要素からなるものを使用することもできる。
According to a further preferred refinement of the invention, the shape of the pressure element is such that a substantially point-like pressure region can be created within the sheet shape. This avoids the movement of the seat cushion or the backrest, or at least the majority of its entire area, by moving one element as well. Pressing in the form of dots has the particular advantage that the sheet shape can be preset in more various forms, as well as the variety of massage functions that can be achieved with the sheet. The shape of the pressurizing element that is substantially adapted to generate the pressure region in a point-like manner is, for example, an oval or circular shape with a boundary seam on the side, so that the element is pressurized Is enlarged only in the transverse direction with respect to the substantially sheet-shaped surface. As an alternative to the shape of the pressure element so that pressure can be generated in the form of dots, a bellows-like side region connected by opposing sheet-like side walls may be provided. Here too, pressure is generated substantially in the direction of the surface of the seat surface and of the backrest, and in this connection the element expands on both sides , so that a sheet-like (non-point-like) pressure is also present. It does not occur. Of course, instead of this, according to this aspect of the present invention, other substantially point-like pressurization, i.e. constant and effective pressurization, and any other setting of the desired sheet shape can be achieved with respect to the massaging operation. It is also possible to use a pressing element having an arbitrary shape.

本発明の別の好ましい改良形態によれば、加圧要素は、それぞれ別個のラインによって動作することができ、このラインは、支持挿入物の表面に配置され、固定され、制御要素の方向にまとめて１つにされる。このような配置により、簡単な、シート状の支持挿入物をシートの層に適合させ、固定させれば良いので、車両シートの生産中、圧力要素の及びそれらのラインの設置が簡単なものとなる。その上、制御装置の又は圧力発生装置の接続ラインは、このため、できる限り短いものとなり、加圧された時の、これに対応する反応時間が、これに対応して短くなる。さらに、支持挿入物の表面に固定することは、必要な空間容積が、垂直方向で最小限まで減少するという利点を有する。   According to another preferred refinement of the invention, the pressure elements can each be operated by a separate line, which is arranged on the surface of the support insert, fixed and grouped in the direction of the control element. To be one. With such an arrangement, a simple, sheet-like support insert can be fitted and secured to the layers of the seat, so that during the production of vehicle seats, the installation of the pressure elements and their lines is simplified. Become. In addition, the connecting line of the control device or of the pressure generator is therefore as short as possible, and the corresponding reaction time when pressurized is correspondingly shortened. Furthermore, securing to the surface of the support insert has the advantage that the required spatial volume is reduced to a minimum in the vertical direction.

本発明のさらに好ましい改良形態によれば、加圧要素は、空気圧又は電気空圧により加圧できる。代替形態として、流体による加圧がなされることもあるが、漏れの問題を考えると、空気を使用することが好ましい。   According to a further preferred refinement of the invention, the pressurizing element can be pressurized by pneumatic or electropneumatic pressure. As an alternative, pressurization by a fluid may be performed, but it is preferable to use air in consideration of a leakage problem.

本発明のさらに好ましい改良形態によれば、コントローラは、予め設定され、かつ個々に設定可能な複数のマッサージ機能を行うよう適応される。マッサージ機能は、シート形状の領域内の特定の圧力要素を組み合わせて、周期的に変える及び／又は個々に作動させることによって実現される。特に、このことにより、たとえば、身体の個々の領域の一定のマッサージを含む、反射区のマッサージなどの、既知の種類のマッサージを実施することができる。   According to a further preferred refinement of the invention, the controller is adapted to perform a plurality of massage functions which are preset and can be set individually. The massage function is realized by combining specific pressure elements within the sheet-shaped region, periodically changing and / or individually actuating. In particular, this makes it possible to carry out known types of massage, such as, for example, a reflex area massage, including a certain massage of individual areas of the body.

本発明の別の好ましい改良形態によれば、シート形状の、複数の予め選択された設定は、コントローラによって格納できる。このことにより、長い間運転している場合に重要な、シート形状の一定の適応を、異なる車両ユーザのために、特にトラックの場合に、それぞれの場合において格納することができる。シート位置（シートの高さ、背もたれの勾配、ペダルからの距離など）を予め設定するのと同様の方法で、特定のシート形状も、特に適応でき、この適応形態において、格納できることが好ましい。特定の運転者がしなければならないことは、自分の体格のために最適化されて予め設定されたものを選択するだけであり、このことは、加圧要素を介してコントローラによって実現される。   According to another preferred refinement of the invention, a plurality of preselected settings of the sheet shape can be stored by the controller. This allows a certain adaptation of the seat shape, which is important when driving for a long time, to be stored in each case for different vehicle users, in particular in the case of trucks. A particular seat shape can be particularly adapted and preferably stored in this adapted manner in a manner similar to presetting the seat position (seat height, backrest gradient, distance from the pedal, etc.). All that a particular driver has to do is select a preset that is optimized for his physique, which is realized by the controller via the pressurizing element.

本発明のさらなる利点、好ましい改良形態、及び詳細が、図面に例示した例示的実施形態を参照しながら、本発明についてより詳細に記述し、説明する、以下の記述より見出され得る。   Further advantages, preferred refinements and details of the invention can be found from the following description, which describes and describes the invention in more detail with reference to the exemplary embodiments illustrated in the drawings.

マッサージ機能及び形状調整を組み合わせた、本発明による車両シートの第１の例示的実施形態が、図１の、斜めから見た図に概略的に例示されている。知られているように、車両シート１は、関節式に相互に接続されたシートクッション２と背もたれ３とを備える。車両シート１には、そのカバー８の下に、各接続ライン６を介して、圧力発生装置（図示せず）による空気圧で動作できる、複数の加圧要素又は空気圧要素４が設けられる。空気圧要素４は、比較的小さい体積又は表面の拡大を有することが好ましく、これにより、実質的に点状に圧力が発生することが可能となる。ここに示されている例示的実施形態においては、空気圧要素４の形状は、実質的に楕円形又は円形であり、小さい圧力パッド又は圧力クッションが、車両シート１のシート形状の選択された領域内に形成される。代替形態として、シート形状全体に、例示されている空気圧要素４が設けられることがある。空気圧要素４は、シート状の支持挿入物９に適合され、固締されるので、シート形状の表面内のそれらの各位置が、正確に確立される。その上、このことにより、組立てが容易になる。空気圧要素４の作動は、シートバック３の領域内に配置されたコントローラ５を介して、それ自体で、組合せて、又は順次に行われる。それぞれの空気圧要素４には、それぞれ別個の接続ライン６を介して、コントローラにより、必要な空気圧が別々に提供される。したがって、一定のシート形状の実現と全く同様のマッサージ機能の実現も、媒体又は圧縮空気内の比較的小さい体積、即ち比較的低い圧力で、有効かつ効果的な方法で実現できる。   A first exemplary embodiment of a vehicle seat according to the present invention combining a massage function and shape adjustment is schematically illustrated in the oblique view of FIG. As is known, the vehicle seat 1 includes a seat cushion 2 and a backrest 3 that are connected to each other in an articulated manner. The vehicle seat 1 is provided with a plurality of pressurizing elements or pneumatic elements 4 that can be operated by air pressure by a pressure generating device (not shown) via the connection lines 6 under the cover 8. The pneumatic element 4 preferably has a relatively small volume or surface enlargement, which allows the pressure to be generated substantially in the form of dots. In the exemplary embodiment shown here, the shape of the pneumatic element 4 is substantially oval or circular, and a small pressure pad or pressure cushion is within a selected region of the seat shape of the vehicle seat 1. Formed. As an alternative, the illustrated pneumatic element 4 may be provided throughout the seat shape.

The construction and structure of the vehicle seat can be found here. That is, the construction of the seat cushion 2 and the seat back 3 of the vehicle seat 1 respectively comprises, in particular, an unsprung installation 11, a stuffing 7, a lining 10, and a cover 8 covering these elements. In this exemplary embodiment, an insert according to the invention of a pneumatic element for massage function and seat shape adjustment is arranged between the padding 7 and the lining 10. A relatively small, separate pneumatic element 4 is arranged in the vicinity of the seat-shaped surface of the vehicle seat 1 and allows adjustment of specific areas or points of the seat surface and back surface with low pressure and small volume. . The controller 5 is preferably arranged in the region of the backrest 3 and therefore no additional space volume is required.

図３は、本発明による車両シートの例示的実施形態を、図２と同様の図で例示した図であり、２つの選択された空気圧要素４が、ここでは加圧状態で例示されている。２つの加圧された空気圧要素４は、それぞれ、予め定められた点で局部的な膨らみを作るが、実質的に、車両シートの形状全体は変化しない。つまり、２つの要素４が加圧された後、再び元のシート形状になることが確実である。同様に、図３に例示されている状況は、ある運転者の身体に対して最適な整形外科的な適応形態又は他の種類の適応形態のための、腰椎領域内及び前部シート面領域内にそれぞれの高さを有する、この運転者の予め選択された一定のシート形状であり得る。   FIG. 3 is a diagram illustrating an exemplary embodiment of a vehicle seat according to the present invention in a view similar to FIG. 2, in which two selected pneumatic elements 4 are illustrated here in a pressurized state. The two pressurized pneumatic elements 4 each create a local bulge at a predetermined point, but substantially the entire shape of the vehicle seat does not change. In other words, after the two elements 4 are pressed, it is certain that the original sheet shape is obtained again. Similarly, the situation illustrated in FIG. 3 is within the lumbar region and the anterior seat surface region for an orthopedic or other type of adaptation that is optimal for a driver's body. The driver may have a pre-selected constant seat shape with respective heights.

図４は、本発明による空気圧要素又は圧力要素４の形状の変形形態を例示する図である。図４に例示されている形状のすべてに共通する特徴は、この形状が、空気圧要素による実質的に点状の加圧が可能となる形状であることである。その上、要素４は、その体積が比較的小さく、シート形状の表面全体に対して、その表面の拡大も小さい。それぞれの空気圧要素４には、各ライン接続６が設けられ、これを介して圧力が供給され、また再び圧力を取り去ることができる。点状に圧力を発生できる例として例示されている形状の変形形態は、以下の形状である。即ち、楕円形、眼の形、側方がくびれた蛇腹型の形、２室形、出っ張り状の膨らみを有する長円形、及び複数の出っ張りが形成された長円形である。勿論、少ない空間しか必要とせずに、実質的に点状に圧力を発生させることが可能である限り、マッサージ及び車両シートのシート形状の調整のための本発明による配置について、他の形状及び変形形態が好適であることもある。   FIG. 4 is a diagram illustrating a variation of the shape of the pneumatic or pressure element 4 according to the invention. A feature common to all of the shapes illustrated in FIG. 4 is that the shape is capable of substantially point-like pressurization by a pneumatic element. Moreover, the element 4 has a relatively small volume and its surface expansion is small relative to the entire sheet-shaped surface. Each pneumatic element 4 is provided with a respective line connection 6 through which pressure is supplied and pressure can be removed again. Variations of the shape illustrated as an example that can generate pressure in the form of dots are the following shapes. That is, an oval shape, an eye shape, a bellows shape with a constricted side, a two-chamber shape, an oval shape with a protruding bulge, and an oval shape with a plurality of ledges formed. Of course, other configurations and variations of the arrangement according to the present invention for massage and adjustment of the seat shape of the vehicle seat are possible as long as it is possible to generate pressure in a substantially point-like manner, requiring less space. The form may be preferred.

図５は、個々の空気圧要素４（例示せず）に対する各ライン接続６の設計及び配置の、２つの変形形態を示す図である。例示されている第１の変形形態のライン６は、支持挿入物９上に配置され、固締された円筒形の管路であり、コントローラ又は圧力発生装置（例示せず）の方向に、まとめて１つにされている。支持挿入物９上に固定することは、組立てがより容易になるという利点を有し、支持挿入物９の表面上に固締することは、垂直方向に少ない空間容積しか必要としないという利点を有する。代替形態として、例示されている第２の変形形態においては、複数の水路状の、断面が矩形のライン６が支持挿入物９上に設けられ、たとえば複数の薄膜層を溶接することによって実現できる。   FIG. 5 shows two variants of the design and arrangement of each line connection 6 for an individual pneumatic element 4 (not shown). The illustrated first variant line 6 is a clamped cylindrical line placed on a support insert 9 and is bundled in the direction of a controller or pressure generator (not shown). Is one. Fixing on the support insert 9 has the advantage that it is easier to assemble, and clamping on the surface of the support insert 9 has the advantage that only a small space volume is required in the vertical direction. Have. As an alternative, in the second variant illustrated, a plurality of channel-like lines 6 having a rectangular cross section are provided on the support insert 9 and can be realized, for example, by welding a plurality of thin film layers. .
