Description

Sitz, insbesondere Fahrzeugsitz, und Verfahren zu seiner Herstellung Seat, in particular vehicle seat, and method for its production
Beschreibungdescription
Die Erfindung betrifft einen Sitz, insbesondere für ein Kraftfahrzeug, mit einer über Gelenkeinrichtungen schwenkbar angeordneten Rückenlehne mit einem Polsterkörper und einem diesen zumindest partiell abdeckenden Sitzbezug, wobei die Gelenkeinrichtung mindestens ein von der Sitzbasis nach oben ragendes Beschlagteil aufweist, welches in eine schlitzförmige Ausnehmung der Rückenlehne ragt und dort mit dieser gelenkig verbunden ist, sowie ein Verfahren zur Herstellung eines derartigen Sitzes.The invention relates to a seat, in particular for a motor vehicle, with a backrest which can be pivoted via articulated devices, with a cushion body and a seat cover which at least partially covers it, the articulated device having at least one fitting part which projects upward from the seat base and which fits into a slot-shaped recess in the backrest protrudes and is articulated there, as well as a method for producing such a seat.
Stand der TechnikState of the art
Ein gattungsgemäßer Fahrzeugsitz ist aus der Druckschrift DE 38 00 924 A1 bekannt. Der dort beschriebene Sitz besteht aus einem Sitzteil und einer gegenüber diesem neigungsverstellbaren Rückenlehne, die jeweils eine gepolsterte und mit einem Sitzbezug versehene Metallstruktur aufweisen. Von der als Sitzbasis fungierenden Metallstruktur des Sitzteils ragen zwei quer zur Sitzrichtung beabstandete Beschlagteile nach oben, mit welchen die Metallstruktur der Rückenlehne über weitere Beschlagteile gelenkig verbunden ist. Im Bereich der nach oben ragenden Beschlagteile sind Polster und Sitzbezug der Rückenlehne mit schlitzförmigen Ausnehmungen versehen, die eine Kollision zwischen dem Beschlagteil und der Rückenlehne bei der Neigungsverstellung vermeiden.A generic vehicle seat is known from the document DE 38 00 924 A1. The seat described there consists of a seat part and a backrest that can be tilted relative to it, each of which has a padded metal structure provided with a seat cover. From the metal structure of the seat part that acts as the seat base, two fitting parts spaced transversely to the seat direction protrude upwards, with which the metal structure of the backrest is articulated via further fitting parts. In the area of the upwardly projecting fittings, the upholstery and seat cover of the backrest have slit-shaped recesses provided that avoid a collision between the fitting part and the backrest during the inclination adjustment.
Derartige Sitzkonstruktionen sind verbreitet und haben sich in der Praxis bewährt. Bei großen schlitzförmigen Ausnehmungen in Verbindung mit dünnen Sitzpolstern, insbesondere bei Fahrzeugrücksitzen, kann jedoch das Problem auftreten, dass die unteren, jenseits der Gelenkeinrichtungen befindlichen Randbereiche der Polsterung eine geringe Steifigkeit aufweisen, wodurch die Spannung des Sitzbezugs in diesem Bereich unzureichend ist. Dies beeinträchtigt zwar nicht die Funktion, kann jedoch durch Falten oder Verzug zu einer Verschlechterung der Optik des betreffenden Sitzes führen.Such seat constructions are common and have proven themselves in practice. In the case of large slot-shaped recesses in connection with thin seat cushions, in particular in the case of vehicle rear seats, however, the problem can arise that the lower edge regions of the upholstery located beyond the articulation devices have a low level of rigidity, as a result of which the tension of the seat cover in this area is insufficient. Although this does not impair the function, it can lead to a deterioration in the appearance of the seat in question due to folding or warping.
Aufgabetask
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Sitz mit verbesserten optischen Eigenschaften bereitzustellen.The invention has for its object to provide a generic seat with improved optical properties.
Lösungsolution
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Unterkante des Sitzbezugs in Bereich der schlitzförmigen Ausnehmung mit Mitteln zur Aufnahme eines Befestigungselements ausgestattet ist, welches mit der Sitzbasis verbindbar ist. Infolge dieser Ausbildung wird gewährleistet, dass die seitlichen Polsterteile der Rückenlehne auch dann ihre Designposition einnehmen, wenn die Rückenlehne zuvor in erheblichem Maße verschwenkt wurde, beispielsweise durch Vorklappen auf das Sitzteil. Die betreffenden Bereiche des Sitzbezugs sind daher in Designposition stets ausreichend und reproduzierbar vorgespannt. Um eine Montage auch bei relativ breiten abzuspannenden Polsterbereichen zu ermöglichen, wird nach einer bevorzugten Ausführungsform der Erfindung vorgeschlagen, das Befestigungselement mit einem an der Sitzbasis angeordneten Befestigungsgegenelement lösbar zu verbinden.The object is achieved in that the lower edge of the seat cover in the area of the slot-shaped recess is equipped with means for receiving a fastening element which can be connected to the seat base. As a result of this design, it is ensured that the side cushion parts of the backrest also assume their design position if the backrest has previously been pivoted to a considerable extent, for example by folding forward onto the seat part. The relevant areas of the seat cover are therefore always sufficiently and reproducibly pre-tensioned in the design position. In order to enable assembly even with relatively wide upholstery areas to be braced, it is proposed according to a preferred embodiment of the invention to releasably connect the fastening element to a fastening counter-element arranged on the seat base.
Die Mittel zur Aufnahme des Befestigungselements umfassen vorzugsweise eine in den Sitzbezug eingelassene, taschenartige Lasche. Mit Vorteil ist das Befestigungselement als sich längserstreckender, insbesondere zylinderförmiger Körper ausgebildet, welcher im Wesentlichen parallel zur Gelenkachse von der schlitzförmigen Ausnehmung her in die Lasche des Sitzbezugs einschiebbar ist. Ferner ist der sich längserstreckende Körper nachfolgend vorzugsweise in umgekehrter Richtung entlang Längsachse auf und/oder in das Befestigungsgegenelement auf- und/oder einschiebbar. Hierzu kann der sich längserstreckende Körper hülsenartig ausgebildet werden, so dass er auf ein zylinderförmiges Befestigungsgegenelement aufschiebbar ist. Dieses kann seinerseits als Schraubenkopf einer zur Fixierung des Beschlagteils an der Sitzbasis verwendbaren Schraube ausgebildet werden, so dass die Erfindung im Wesentlichen durch Modifikation ohnehin vorhanderer Bauteile des Sitzes realisierbar ist.The means for receiving the fastening element preferably comprise a pocket-like tab embedded in the seat cover. The fastening element is advantageously designed as a longitudinally extending, in particular cylindrical, body which can be pushed into the tab of the seat cover essentially parallel to the hinge axis from the slot-shaped recess. Furthermore, the longitudinally extending body can subsequently preferably be pushed and / or pushed in in the opposite direction along the longitudinal axis onto and / or into the fastening counter-element. For this purpose, the longitudinally extending body can be designed like a sleeve, so that it can be pushed onto a cylindrical fastening counter-element. This in turn can be designed as a screw head of a screw that can be used to fix the fitting part to the seat base, so that the invention can be implemented essentially by modifying existing components of the seat.
Der Sitzbezug wird durch Verbinden des Befestigungselements mit dem Befestigungsgegenelement in aufrechter Lehnenstellung üblicherweise nach unten gespannt, um die gewünschte falten- und verzugfreie Lage des Sitzbezugs zu bewirken.The seat cover is usually stretched downwards by connecting the fastening element to the fastening counter element in the upright backrest position in order to bring about the desired wrinkle-free and warp-free position of the seat cover.
Das Verfahren zur Herstellung eines erfindungsgemäßen Sitzes ist dadurch gekennzeichnet, dass zunächst die Sitzbasis sowie die gepolsterte und mit dem Sitzbezug und der Gelenkeinrichtung versehene Rückenlehne gefertigt wird. Diese wird nachfolgend auf die Sitzbasis aufgesetzt, wobei die nach oben ragenden Beschlagteile der Gelenkeinrichtungen mit der Sitzbasis unter Ausbildung der Befestigungs- oder Befestigungsgegenelemente verbunden werden. Durch Einbringen des Befestigungselements in die Tasche wird dem Sitzbezug die notwendige Spannung verliehen.The method for producing a seat according to the invention is characterized in that first the seat base and the upholstered backrest provided with the seat cover and the articulation device are manufactured. This is subsequently placed on the seat base, the upwardly projecting fitting parts of the articulation devices with the seat base to form the fastening or fastening counter-elements get connected. By inserting the fastener into the bag, the seat cover is given the necessary tension.
Falls sowohl ein Befestigungselement als auch das zugeordnete Befesti- gungsgegenelement verwendet werden, wird das Befestigungselement nach dem Einbringen in den Sitzbezug vorzugsweise mit dem zuvor mit der Sitzbasis verbundenen Befestigungsgegenelement lösbar formschlüssig verbunden.If both a fastening element and the associated fastening mating element are used, the fastening element is preferably detachably positively connected to the fastening mating element previously connected to the seat base after being introduced into the seat cover.

Fig. 5 die Ausführung nach Fig. 3 in seitlicher Ansicht. Die in Fig. 1 dargestellte Fahrzeugrücksitzbank 1 besteht aus einem Sitzteil 2 und einer Rückenlehne 3, die über zwei zueinander quer zur Fahrtrichtung beabstandete, gegebenenfalls sperrbare Gelenkeinrichtungen 4 um eine horizontale Drehachse 5 gegenüber dem Sitzteil 2 schwenkbar ist. Im Bereich der Gelenkeinrichtungen 4 ist die Rückenlehne 3 mit von deren Unterkante nach oben führenden schlitzförmigen Ausnehmungen 6 versehen.Fig. 5 shows the embodiment of FIG. 3 in a side view. The vehicle rear bench seat 1 shown in FIG. 1 consists of a seat part 2 and a backrest 3 which can be pivoted about a horizontal axis of rotation 5 with respect to the seat part 2 by means of two articulated devices 4 spaced apart from one another transversely to the direction of travel. In the area of the articulation devices 4, the backrest 3 is provided with slot-shaped recesses 6 leading upward from its lower edge.
Wie aus Fig. 2 ersichtlich, besteht jede Gelenkeinrichung 4 aus einem von der Sitzbasis 7 nach oben ragenden ersten Beschlagteil 8, das gelenkig mit einem zweiten, an der Metallstruktur 9 der Rückenlehne 3 angeordneten Beschlagteil 10 verbunden ist. Die Sitzbasis 7 kann ein Bauteil sein, auf welches das Sitzteil 2 aufsetzbar ist, oder einen Bestandteil der Metallstruktur des Sitzteils 2 darstellen. Im erstgenannten Fall könnte die Sitzbasis 7 sogar einstückig an die Fahrzeugkarosserie angeformt werden. Das erste Beschlagteil 8 ist über eine Lasche 11 und mittels Schrauben 12, 12' starr mit der Sitzbasis 7 verbunden, von denen in Fig. 2 nur die vorderste Schraube 12 sichtbar ist.As can be seen from FIG. 2, each articulation device 4 consists of a first fitting part 8 which projects upwards from the seat base 7 and which is articulated to a second fitting part 10 arranged on the metal structure 9 of the backrest 3. The seat base 7 can be a component on which the seat part 2 can be placed, or it can be part of the metal structure of the seat part 2. In the former case, the seat base 7 could even be integrally formed on the vehicle body. The first fitting part 8 is rigidly connected to the seat base 7 via a tab 11 and by means of screws 12, 12 ', of which only the foremost screw 12 is visible in FIG. 2.
Die Metallstruktur 9 der Rückenlehne 3 ist mit einem Polsterkörper 13 versehen, der mit einem Sitzbezug 14 überzogen ist. Jenseits der Gelenkeinrichtung 4 bildet der Polsterkörper 13 einen nur oben angebundenen Flügel 15 aus, der eine geringe Steif igkeit aufweist und bei der Montage der Schraube 12 nach vorne oder hinten verschwenkt werden kann. Im unteren Bereich des Flügels 15 ist eine Tasche 16 in den Sitzbezug 14 eingearbeitet, die nur zur Schraube 12 hin geöffnet ist. In diese Tasche 16 greift ein zylinderförmiges, sich parallel zur Drehachse 5 erstreckendes Befestigungselement 17 ein, welches den Flügel 15 bei Gebrauchsstellung der Rückenlehne 3 nach unten vorspannt und den Sitzbezug 14 in diesem Bereich strafft. Das Befestigungselement 17 ist im Ausführungsbeispiel unmittelbar als verlängerter Schraubenkopf 18 der Schraube 12 ausgebildet, so dass zur Durchführung der Erfindung keine zusätzlichen Bauteile erforderlich. Grundsätzlich könnte jedoch auch ein mit dem Beschlagteil 8 beispielsweise durch Schweißen unlösbar verbundenes Befestigungselement verwendet werden.The metal structure 9 of the backrest 3 is provided with a cushion body 13, which is covered with a seat cover 14. Beyond the articulation device 4, the cushion body 13 forms a wing 15 which is only connected at the top and has a low rigidity and can be pivoted forwards or backwards when the screw 12 is installed. In the lower area of the wing 15, a pocket 16 is incorporated into the seat cover 14, which is only open towards the screw 12. A cylindrical fastening element 17, which extends parallel to the axis of rotation 5, engages in this pocket 16, which biases the wing 15 downward when the backrest 3 is in use and tightens the seat cover 14 in this area. In the exemplary embodiment, the fastening element 17 is designed directly as an elongated screw head 18 of the screw 12, so that no additional components are required to carry out the invention. In principle, however, a fastening element could also be used which is permanently connected to the fitting part 8, for example by welding.
Bei der Fertigung der Fahrzeugrücksitzbank wird die mit der funktionsfähigen Gelenkeinrichtung 4 versehene Rückenlehne 3 auf die Sitzbasis 7 derart aufgesetzt, dass das Beschlagteil 8 durch die Schraube 12 mit der Lasche 11 starr verbindbar ist. Hierzu muß der Flügel 15 nach vorne oder hinten gebogen werden, so dass der Schraubenkopf 18 zugänglich ist.In the manufacture of the vehicle rear seat bench, the backrest 3 provided with the functional joint device 4 is placed on the seat base 7 in such a way that the fitting part 8 can be rigidly connected to the bracket 11 by the screw 12. For this purpose, the wing 15 must be bent forwards or backwards so that the screw head 18 is accessible.
Anschließend wird der Schraubenkopf 18 unter nochmaliger Verformung des Flügels 15 in die Tasche 16 eingeführt.The screw head 18 is then inserted into the pocket 16 with further deformation of the wing 15.
Falls der Flügel ein ungünstiges Höhen/Breitenverhältnis aufweist und/oder aufgrund seiner Steifigkeit eine derartige Verformung nicht schadlos zuläßt, kann durch die in den Fig. 3 bis 5 gezeigte Weiterentwicklung Abhilfe geschaffen werden.If the wing has an unfavorable height / width ratio and / or because of its rigidity such deformation does not allow harmless, the further development shown in FIGS. 3 to 5 can be used to remedy the situation.
Bei der dort gezeigten Ausführung ist der Schraubenkopf 18 kürzer ausgeführt, so dass er nicht oder nur geringfügig in die Tasche 16 hineinragt. Die komplexe Verformung des Flügels 15 beim Einführen des Schraubenkopfes 18 ist somit geringer oder kann sogar ganz entfallen. In die Tasche 16 wird stattdessen als Befestigungselement 17 vorab eine der Taschenlänge entsprechende Hülse 19 eingeschoben, die nachfolgend auf den relativ kurzen Schraubenkopf 18 als Befestigungsgegenelement 20 aufgesetzt und dadurch indirekt mit der Sitzbasis verbunden wird. Wie in Fig. 4 dargestellt, ist hierzu nur eine der Länge des Schraubenkopfes 18 entsprechende geringer Verformung des Flügels 15 erforderlich. Eine Demontage der Rückenlehne 3 wird durch die beschriebenen Ausführungen nicht behindert, da die Vorspannung des Flügels 15 durch Herausziehen des Befestigungs- oder Befestigungsgegenelements 17, 20 aus der Tasche 16 reversibel ist. In the embodiment shown there, the screw head 18 is shorter, so that it does not protrude into the pocket 16, or protrudes only slightly. The complex deformation of the wing 15 when inserting the screw head 18 is thus less or can even be omitted entirely. Instead, a sleeve 19 corresponding to the pocket length is inserted into the pocket 16 as a fastening element 17, which is subsequently placed on the relatively short screw head 18 as a fastening counter-element 20 and thereby indirectly connected to the seat base. As shown in FIG. 4, only a slight deformation of the wing 15 corresponding to the length of the screw head 18 is required for this. Dismantling of the backrest 3 is not hindered by the described embodiments, since the pretensioning of the wing 15 is reversible by pulling the fastening or fastening counter-element 17, 20 out of the pocket 16.
