Description
Sitz, insbesondere Rücksitz eines Kraftfahrzeugs, sowie zur Verwendung bei einem derartigen Sitz geeigneter Polsterbezug Seat, in particular rear seat of a motor vehicle, and upholstery cover suitable for use with such a seat
Beschreibungdescription
Die Erfindung betrifft einen Sitz, insbesondere den Rücksitz eines Kraftfahrzeugs, mit einem Sitzteil und einer relativ zu diesem aus einer Gebrauchs- Stellung in eine Nichtgebrauchsstellung bewegbaren Rückenlehne, die in vertikal nach oben in schlitzförmige Ausnehmungen der Rückenlehne ragenden Gelenkblechen drehbar gelagert ist, sowie einen bei einem derartigen Sitz verwendbaren Polsterbezug.The invention relates to a seat, in particular the rear seat of a motor vehicle, with a seat part and a backrest which can be moved relative to this from a use position into a non-use position and which is rotatably mounted in joint plates which project vertically upward into slot-shaped recesses in the backrest, and one at such a usable cushion cover.
Stand der TechnikState of the art
Ein gattungsgemäßer Rücksitz für ein Kraftfahrzeug ist aus der Praxis bekannt. Er weist ein im Wesentlichen horizontales Sitzteil auf, das aus einem geschäumten Polsterteil und einer metallische Unterkonstruktion besteht und sowohl starr als auch längsverschieblich oder schwenkbar im Fahrzeuginnenraum angeordnet werden kann. Der Sitz ist ferner mit einer Rückenlehne versehen, die zur Vergrößerung des Ladevolumens des Kofferraums aus einer aufrechten Gebrauchslage um eine oberhalb des Sitzteils horizontal und quer zur Fahrtrichtung verlaufende Drehachse nach vorne in eine waagerechte Nichtgebrauchslage geklappt werden kann. Das
Drehgelenk besteht dabei aus Gelenkblechen, die starr mit der metallischen Unterkonstruktion des Sitzteils verbunden sind und senkrecht nach oben in die Rückenlehne hineinragen. Die mit den Gelenkblechen drehbar verbundene Rückenlehne ist in diesem Bereich mit vertikal verlaufenden, schlitzförmigen Ausnehmungen versehen, die sich üblicherweise von der Rückseite bis zur Anlagefläche für den Sitzinsassen erstrecken.A generic rear seat for a motor vehicle is known from practice. It has an essentially horizontal seat part, which consists of a foamed upholstery part and a metallic substructure and can be arranged in the vehicle interior both rigidly and longitudinally displaceably or pivotably. The seat is also provided with a backrest, which can be folded forward from an upright position of use about an axis of rotation horizontally and transversely to the direction of travel to a horizontal non-use position to increase the loading volume of the trunk. The The swivel joint consists of joint plates that are rigidly connected to the metal substructure of the seat part and protrude vertically upwards into the backrest. The backrest, which is rotatably connected to the joint plates, is provided in this area with vertically running, slot-shaped recesses which usually extend from the rear to the contact surface for the seat occupant.
Die Polsterteile von Sitzteil und Rückenlehne sind ferner auf der dem Sitzinsassen zugewandten Seite mit einem bevorzugt einstückigen, gegebenenfalls jedoch auch mehrteiligen Polsterbezug versehen. Dieser Bezug weist im Wesentlichen, das heißt in den die Polsterteile bedeckenden Bereichen eine geringe Dehnfähigkeit auf und kann beispielsweise aus Leder gefertigt werden. Der Polsterbezug ist im Bereich der Ausnehmungen der Rückenlehne mit korrespondierenden schlitzförmigen Durchbrüche versehen. Infolge dieser Ausbildung wird eine durch Kontakt mit den Gelenkblechen verursachte Beschädigung des Polsterbezugs beim Umklappen der Rückenlehne vermieden. Die Durchbrüche und die in ihnen angeordneten Gelenkbleche sind allerdings von Fahrzeuginnenraum her sichtbar. Diese bekannten Sitze sind darüber hinaus im Hinblick auf das Eindringen von Verschmutzungen in den Gelenkbereich und die Vermeidung von Verletzungen beim Umklappen unbefriedigend.The cushion parts of the seat part and backrest are also provided on the side facing the seat occupant with a preferably one-piece, but possibly also multi-part cushion cover. This cover essentially has a low elasticity in the areas covering the upholstery parts and can be made of leather, for example. The upholstery cover is provided with corresponding slit-shaped openings in the area of the recesses in the backrest. As a result of this design, damage to the upholstery cover caused by contact with the joint plates is avoided when the backrest is folded down. The openings and the articulated plates arranged in them are visible from the vehicle interior. These known seats are also unsatisfactory with regard to the penetration of dirt into the joint area and the avoidance of injuries when folding down.
Aufgabetask
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Sitz mit einem optisch und funktionell befriedigendem Polsterbezug bereitzustellen.
LösungThe invention has for its object to provide a generic seat with a visually and functionally satisfactory cushion cover. solution
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Polsterbezug die schlitzförmigen Ausnehmungen der Rückenlehne sitzteilseitig zumindest teilweise abdeckt und im Bereich dieser Abdeckungen aus einem elastisch dehnbaren Material gefertigt ist.The object is achieved according to the invention in that the upholstery cover at least partially covers the slot-shaped recesses in the backrest on the seat part side and is made of an elastically stretchable material in the area of these covers.
Durch diese Ausbildung sind die schlitzförmigen Ausnehmungen vom Fahrzeuginnenraum her in Gebrauchsstellung der Rückenlehne nicht oder nur geringfügig sichtbar und vor Verschmutzung oder Eingriff weitgehend geschützt. Beim Umklappen in die Nichtgebrauchsstellung, bei welcher die Gelenkbleche nicht mehr von der Unterseite, sondern von der Sitzfläche her in die Rückenlehne hineinragen, paßt sich die Abdeckung hingegen der Kontur der Gelenkbleche an.As a result of this design, the slot-shaped recesses are not or only slightly visible from the vehicle interior in the use position of the backrest and are largely protected against contamination or interference. When folding down into the non-use position, in which the joint plates no longer protrude into the backrest from the bottom, but from the seat, the cover adapts to the contour of the joint plates.
Die Rückenlehne ist dabei mit Vorteil über zumindest zwei zueinander beabstandete Gelenkbleche drehbar mit dem Sitzteil verbunden, wobei sich ein die elastischen Abdeckungen miteinander spannend verbindendes elastisches Element, insbesondere ein Spannband vom Polsterbezug durch die schlitzförmigen Ausnehmungen über die Rückseite der Rückenlehne erstreckt. Das elastische Element unterstützt die Rückverformung der elastischen Abdeckung nach dem Wiederaufrichten der Rückenlehne und gewährleistet in Gebrauchsstellung eine faltenfreie und sichere Anlage des Polsterbezugs an der Rückenlehne.The backrest is advantageously rotatably connected to the seat part via at least two spaced-apart joint plates, wherein an elastic element that connects the elastic covers to one another, in particular a tensioning strap, extends from the upholstery cover through the slot-shaped recesses over the back of the backrest. The elastic element supports the reshaping of the elastic cover after the backrest has been straightened up and, in the position of use, ensures that the upholstery cover is securely and wrinkle-free against the backrest.
Ein bei einem derartigen Sitz verwendbarer Polsterbezug besteht aus einem ersten, dem Sitzteil zugeordneten Bezugssegment und einem zweiten, der Rückenlehne zugeordneten Bezugssegment, das im Übergangsbereich zum ersten Bezugssegment schlitzförmige Durchbrüche aufweist, welche durch Abdeckungen aus einem elastisch dehnbaren Material zumindest teilweise
verschlossen sind. Die Abdeckungen können beispielsweise über vorzugsweise U-förmig ausgeführte Nähte in das Bezugssegment eingebunden werden, wobei die Abdeckungen nicht an das dem Sitzteil zugeordnete Bezugssegment angenäht werden. Zur Verbesserung der Anlage des Polsterbezugs kann ferner ein elastisches Element, insbesondere ein Spannband vorgesehen sein, das sich rückseitig zwischen zwei zueinander beabstandete Abdeckungen erstreckt. Das elastische Element ist dabei bevorzugt in den Nähten der Abdeckungen mit dem Polsterbezug vernäht.A cushion cover that can be used in such a seat consists of a first reference segment assigned to the seat part and a second reference segment assigned to the backrest, which has slot-shaped openings in the transition area to the first reference segment, which at least partially by covers made of an elastically stretchable material are closed. The covers can, for example, be integrated into the reference segment via preferably U-shaped seams, the covers not being sewn onto the reference segment assigned to the seat part. To improve the abutment of the upholstery cover, an elastic element, in particular a tensioning strap, can also be provided, which extends on the back between two spaced-apart covers. The elastic element is preferably sewn in the seams of the covers with the cushion cover.
Die Bruchdehnung des Materials der Abdeckungen beträgt bevorzugt mindestens das 2fache, bevorzugt das 3fache, insbesondere jedoch das 4fache der Bruchdehnung des übrigen Polsterbezugs. Dieser kann im Wesentlichen, also in den die Polsterteile verdeckenden Bereichen beispielsweise aus einem textilen Flächengebilde, insbesondere einem Gewebe, aus einem Leder oder einem Kunstleder mit einer Bruchdehnung von weniger als 100%, bevorzugt weniger als 75%, insbesondere jedoch weniger als 50% bestehen.The elongation at break of the material of the covers is preferably at least 2 times, preferably 3 times, but in particular 4 times the elongation at break of the remaining cushion cover. This can essentially consist, that is, in the areas covering the upholstery parts, for example of a textile fabric, in particular a woven fabric, of a leather or an artificial leather with an elongation at break of less than 100%, preferably less than 75%, but in particular less than 50% ,
Die im Polsterbezug einstückig angeordneten Abdeckungen im Bereich der schlitzförmigen Ausnehmungen der Rückenlehne bestehen hingegen mit Vorteil aus einem mit Elastomerfasern versetzten textilen Flächengebilde, insbesondere einer Polyester- oder Baumwollmaschenware, das eine Bruchdehnung von mindestens 100%, bevorzugt mindestens 150%, insbesondere mindestens 200% aufweist.The covers arranged in one piece in the upholstery cover in the area of the slit-shaped recesses of the backrest, on the other hand, advantageously consist of a textile fabric with elastomer fibers, in particular a polyester or cotton knitted fabric, which has an elongation at break of at least 100%, preferably at least 150%, in particular at least 200% ,

Fig. 4 den Sitz nach Fig. 1 in rückwärtiger AnsichtFig. 4 shows the seat of FIG. 1 in a rear view
Der in den Figuren 1 bis 4 abgebildete Fahrzeugsitz umfaßt ein Sitzteil 1 aus einem Polsterteil 2 und einer metallischen Struktur 3, die mit dem Fahrzeug- boden verbunden ist, sowie eine mit einem Polsterteil 4 versehene Rückenlehne 5, die ihrerseits ebenfalls eine metallische Struktur 6 aufweist. Aus dem hinteren Bereich des Sitzteil 1 ragen zwei zueinander beabstandete, starr mit dessen metallischer Struktur 3 verbundene Gelenkbleche 7 senkrecht nach oben bis in die Rückenlehne 5. Diese ist mit korrespondie- renden Gelenkstücken 8 versehen, die ihrerseits starr mit der metallischen Struktur 6 der Rückenlehne 5 verbunden sind. Gelenkbleche 7 und Gelenkstücke 8 bilden im unteren Teil der Rückenlehne 5 ein Drehgelenk mit einer horizontal und quer zur Blickrichtung des Sitzinsassen ausgerichteten Drehachse 9 aus.
Die Rückenlehne 5 weist im Bereich der Gelenkbleche 7 schlitzförmige Ausnehmungen 10 auf, um einen ausreichenden Bewegungsraum für das Drehgelenk zu schaffen. Während das Gelenkblech 7 in Gebrauchsstellung (Fig. 2) von unten in die Ausnehmung 10 der Rückenlehne 5 eindringt, ragt es in Nichtgebrauchsstellung (Fig. 3) von der Sitzfläche (Anlagefläche des Sitzinsassen) her in die Ausnehmung 10 hinein.The vehicle seat shown in FIGS. 1 to 4 comprises a seat part 1 made of a cushion part 2 and a metallic structure 3, which is connected to the vehicle floor, and a backrest 5 provided with a cushion part 4, which in turn also has a metallic structure 6 , From the rear area of the seat part 1, two articulated plates 7, spaced apart from one another and rigidly connected to its metallic structure 3, project vertically upwards into the backrest 5. This is provided with corresponding articulated pieces 8, which in turn are rigid with the metallic structure 6 of the backrest 5 are connected. Joint plates 7 and joint pieces 8 form in the lower part of the backrest 5 a swivel joint with an axis of rotation 9 oriented horizontally and transversely to the direction of view of the seat occupant. The backrest 5 has slot-shaped recesses 10 in the area of the joint plates 7 in order to create sufficient space for the pivot joint to move. While the joint plate 7 penetrates into the recess 10 of the backrest 5 from below in the use position (FIG. 2), it projects into the recess 10 from the seat surface (contact surface of the seat occupant) in the non-use position (FIG. 3).
Der Fahrzeugsitz ist ferner mit einem einstückigen Polsterbezug 11 aus einem ersten, das Polsterteil 2 des Sitzteils 1 bedeckenden Bezugssegment 12 sowie einem mit diesem vernähten zweiten, das Polsterteil 4 der Rückenlehne 5 bedeckenden Bezugssegment 13 versehen. Die Bezugssegmente 12 und 13 bestehen aus einem Material mit relativ geringer Dehnfähigkeit, beispielsweise Leder, das jedoch im Hinblick auf Optik und Haptik hohe Anforderungen erfüllt.The vehicle seat is further provided with a one-piece upholstery cover 11 comprising a first reference segment 12 covering the upholstery part 2 of the seat part 1 and a second reference segment 13 sewn to the upholstery part 4 of the backrest 5. The reference segments 12 and 13 consist of a material with a relatively low elasticity, for example leather, which, however, fulfills high requirements with regard to appearance and feel.
Das der Rückenlehne 5 zugeordnete Bezugssegment 13 weist im Bereich der schlitzförmigen Ausnehmungen 10 Durchbrüche 14 auf, die den Gelenk- blechen 7 beim Umklappen der Rückenlehne 5 in die Nichtgebrauchsstellung den nötigen Bewegungsraum schaffen und ein Einreißen des Bezugssegments 13 durch einen Kontakt mit den Gelenkblechen 7 verhindern. Die Durchbrüche 14 sind zumindest im oberen Bereich mit einer elastischen Abdeckung 15 verschlossen, die aus einem flächigen Material hoher Dehnfähigkeit bestehen und jeweils über eine U-förmig ausgebildete Naht 16 in den Polsterbezug 11 eingenäht sind, jedoch keine unmittelbar Verbindung zum Bezugssegment 12 aufweisen. In Gebrauchsstellung verschließen die Abdeckungen 15 die schlitzförmigen Ausnehmungen 10 sitzteilseitig im Wesentlichen, so dass die Gelenkbleche 7 und die Gelenkstücke 8 weitgehend unsichtbar und vor versehentlichem Eingriff geschützt sind (Figuren 1 und 2). Beim Umklappen der Rückenlehne 5 legen sich die
elastischen Abdeckungen 15 zuerst an die Gelenkbleche 7 an und werden dann bis zum Erreichen der Nichtgebrauchsstellung gedehnt (Figur. 3). Aufgrund ihrer Elastizität wird ein Einreißen der Abdeckungen 15 oder der die Abdeckungen 15 mit dem Bezugssegment 13 verbindenden Nähte 16 vermieden. Außerdem nehmen die Abdeckungen 15 infolge ihres Rückstellvermögens wieder ihre ursprüngliche Lage ein, wenn die Rückenlehne 5 in die Gebrauchsstellung zurückgeklappt wird.The reference segment 13 assigned to the backrest 5 has openings 14 in the area of the slot-shaped recesses, which create the necessary movement space for the joint plates 7 when the backrest 5 is folded into the non-use position and prevent the reference segment 13 from tearing due to contact with the joint plates 7 , The openings 14 are closed, at least in the upper region, with an elastic cover 15, which consist of a flat material of high elasticity and are sewn into the upholstery cover 11 via a U-shaped seam 16, but have no direct connection to the reference segment 12. In the position of use, the covers 15 essentially close the slot-shaped recesses 10 on the seat part side, so that the hinge plates 7 and the hinge pieces 8 are largely invisible and protected against accidental intervention (FIGS. 1 and 2). When folding the backrest 5 down elastic covers 15 first on the hinge plates 7 and are then stretched until the non-use position is reached (FIG. 3). Because of their elasticity, tearing of the covers 15 or the seams 16 connecting the covers 15 to the reference segment 13 is avoided. In addition, the covers 15 return to their original position due to their resilience when the backrest 5 is folded back into the use position.
Eine einwandfreie Anlage des Sitzbezugs 11 bei erneutem Erreichen der Gebrauchslage wird ferner durch ein elastisches Element 17 in Form eines Spannbands 18 herbeigeführt, das an jedem seiner Enden in den Nähten 16 mit einer der Abdeckungen 15 verbunden ist und sich durch die Ausnehmungen 10 um die Rückseite 19 der Rückenlehne 5 herum erstreckt (Figur 4).
Proper seating of the seat cover 11 when the position of use is reached again is further brought about by an elastic element 17 in the form of a tensioning strap 18, which is connected at each of its ends in the seams 16 to one of the covers 15 and extends through the recesses 10 around the rear 19 of the backrest 5 extends around (Figure 4).
