Description

Kopfstütze für einen Fahrzeugsitz Headrest for a vehicle seat
Die Erfindung betrifft eine Kopfstütze für einen Sitzkissen und Rückenlehne aufweisenden Fahrzeugsitz gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a headrest for a seat cushion and backrest having a vehicle seat according to the preamble of patent claim 1.
Bei einer bekannten Kopfstütze dieser Art (DE 43 05 909 C2) weist der das Kopfpolster tragende Halter zwei im Parallelabstand zueinander verlaufende Haltestangen auf, die an einem Ende durch eine Querstange einstückig miteinander verbunden sind. Die Haltestangen sind in zwei in der Rückenlehne integrierten Führungshülsen höhenverstellbar aufgenommen. Auf der Querstange sitzt ein Drehelement, das seinerseits auf einem rechtwinklig zu der Querstange ausgerichteten U-förmigen Bügel sitzt, an dem die Polsterung des Kopfpolsters befestigt ist. Das Kopfpolster kann damit einerseits in Richtung der Sitztiefe verschoben werden und andererseits in jede Verschiebestellung um eine durch die Querstange verlaufende Schwenkachse gekippt werden. Somit lässt sich das Kopfpolster durch Höheneinstellung an die Körpergröße des Sitzbenutzers anpassen und durch Horizontalverschieben in Richtung Sitztiefe und durch Neigungseinstellung um seine parallel zur Rückenlehne verlaufende Schwenkachse an den Kopf des Sitzenden heranführen. Das Kopfpolster der Kopfstütze kann damit entsprechend der Sitzgröße des Sitzbenutzers immer optimal eingestellt werden, was einerseits ein angenehmes Anlehnen des Hinterkopfes am Kopfpolster erlaubt und anderseits eine unter Sicherheitsaspekten optimale Kopfabstutzung im Crashfall gewährleistet. Dies setzt jedoch voraus, dass der Sitzende die durch die Sitzform des Fahrzeugsitzes vorgegebene normale Sitzhaltung einnimmt, in der sein Körper etwa mittig zum Fahrzeugsitz ausgerichtet ist.In a known headrest of this type (DE 43 05 909 C2), the holder which supports the head cushion has two holding rods which run parallel to one another and which are integrally connected to one another at one end by a transverse rod. The handrails are accommodated in two height-adjustable guide sleeves integrated in the backrest. On the crossbar sits a rotating element, which in turn sits on a U-shaped bracket oriented at right angles to the crossbar, to which the upholstery of the head cushion is attached. The head cushion can thus be moved on the one hand in the direction of the seat depth and on the other hand can be tilted into any displacement position about a pivot axis running through the crossbar. Thus, the headrest can be adjusted to the height of the seat user by adjusting the height and brought to the head of the seated person by moving horizontally in the direction of the seat depth and by adjusting the inclination around its pivot axis running parallel to the backrest. The head cushion of the headrest can thus always be optimally adjusted according to the seat size of the seat user, which on the one hand allows the back of the head to lean comfortably on the head cushion and on the other hand ensures optimal head support in the event of a crash in terms of safety. However, this presupposes that the person sitting the assumes a normal sitting posture predetermined by the seat shape of the vehicle seat, in which its body is aligned approximately in the center of the vehicle seat.
Mitunter nehmen Sitzbenutzer auch von dieser normalen Sitzhaltung abweichende Sitzpositionen ein, wenn sie sich z.B. aus Gründe der zeitweisen Entspannung an den an der Rückenlehne des Fahrzeugsitzes ausgeformten Seitenbacken anlehnen. In einem solchen Fall steht das normalerweise mittig zur Rückenlehen platzierte Kopfpolster der Kopfstütze nicht mehr im Kopfbereich des Sitzenden. Auch bei Fondbänken, die wahlweise mit drei oder zwei Sitzbenutzern belegt werden können, treten Sitzpositionen der Sitzbenutzer auf, bei denen die Kopf ols- ter nicht mehr mittig zum Sitzplatz angeordnet sind. Bei einer Dreierbesetzung der Fondbank sitzen die Sitzbenutzer relativ eng aneinander, wobei jedem Sitzplatz die Kopfstütze funktionsgerecht zugeordnet ist. Ist hingegen die Fondbank nur mit zwei Personen besetzt, so nehmen diese wegen des größeren Platzangebots erfahrungsgemäß eine etwas andere Platzierung ein, bei welcher der Abstand zur Fahrzugseitenwand größer ist. In diesem Fall der Zweierbesetzung der Fondbank sind die Kopfstützen dann seitlich zu den Kopfmitten versetzt und können ihre Abstützfunktion nicht optimal wahrnehmen.Occasionally, seat users also assume sitting positions that deviate from this normal sitting posture, e.g. if they for reasons of temporary relaxation, lean against the side cheeks formed on the backrest of the vehicle seat. In such a case, the head cushion of the headrest, which is normally placed in the center of the backrest, is no longer in the head area of the seated person. Even with rear seats, which can optionally be occupied by three or two seat users, seat positions of the seat users occur in which the heads are no longer arranged in the center of the seat. If the rear bench seats three, the seat users sit relatively close to each other, with the headrest assigned to each seat in a functional manner. If, on the other hand, the rear bench seat is only occupied by two people, experience has shown that due to the larger amount of space available, they occupy a slightly different position in which the distance to the side wall of the vehicle is greater. In this case of two people seated in the rear bench, the headrests are then laterally offset from the center of the head and cannot optimally perform their support function.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Fahrzeugsitz die Kopfstütze so zu gestalten, dass auch bei von dem Sitzbenutzer eingenommen Sitzpositionen auf dem Fahrzeugsitz, die nicht der durch die Sitzform vorgegebenen, normalen Sitzposition entsprechen, die Kopfstütze ihre Abstützfunktion für den Hinterkopf des Sitzbenutzers sowohl im normalen Betrieb als auch im Crashfall zu erfüllen vermag.The invention has for its object to design the headrest in a vehicle seat so that even when the seat user occupies seating positions on the vehicle seat that do not correspond to the normal seating position specified by the seat shape, the headrest serves as a support function for the back of the seat user in normal operation as well as in the event of a crash.
Die Aufgabe ist erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst .The object is achieved by the features of claim 1.
Die erfindungsgemäße Kopfstütze hat den Vorteil, dass durch die nunmehr geschaffene Möglichkeit der Querverschiebung des Kopfpolsters relativ zur Rückenlehne der Sitzbenutzer bei einer Sitzhaltung, in der sein Kopf nicht in Sitzmitte sondern dazu seitlich versetzt ist, das Kopfpolster jetzt soweit verschieben kann, dass es wieder mittig zum Kopf des Sitzenden platziert ist. Damit kann die Kopfstütze in Hinblick auf die Abstützung des Kopfes des Sitzbenutzers in der veränderten Sitzposition in gleich optimaler Weise wirken wie in der durch die Sitzform vorgegebenen, normalen Sitzhaltung des Sitzbenutzers in Sitzmitte.The headrest according to the invention has the advantage that the now created possibility of transverse displacement of the Head cushions relative to the backrest of the seat user in a seated posture in which his head is not offset in the middle of the seat but to the side, can now move the head cushion so far that it is again centered on the head of the seated person. With regard to the support of the head of the seat user in the changed seat position, the headrest can thus act in the same optimal manner as in the normal seat posture of the seat user in the middle of the seat, which is predetermined by the shape of the seat.
Die Querverschiebung des Kopfpolsters relativ zur Rückenlehne, also die Längsverschiebung des Kopfpolsters längs seiner Schwenkachse, kann von Hand vorgenommen werden aber auch durch eine Antriebseinheit bewirkt werden, die auf elektrischer, pneumatischer oder hydraulischer Basis arbeitet.The transverse displacement of the head cushion relative to the backrest, that is to say the longitudinal displacement of the head cushion along its swivel axis, can be carried out by hand but can also be effected by a drive unit which works on an electrical, pneumatic or hydraulic basis.
Vorteilhafte Ausführungsformen der erfindungsgemäßen Kopfstütze mit zweckmäßigen Weiterbildungen und Ausgestaltungen der Erfindung sind in den weiteren Patentansprüchen angegeben.Advantageous embodiments of the headrest according to the invention with expedient further developments and refinements of the invention are specified in the further claims.
Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im folgenden näher beschrieben. Es zeigen in schematischer Darstellung:The invention is described below with reference to an embodiment shown in the drawing. In a schematic representation:

Fig. 3 einen Schnitt längs der Linie III - III in Fig. 2.3 shows a section along the line III-III in FIG. 2.
Der in Fig. 1 ausschnittweise dargestellte Fahrzeugsitz weist in bekannter Weise ein hier nicht zu sehendes Sitzkissen, ei- ne an dem Sitzkissen schwenkbar gehaltene Rückenlehne 10 sowie eine Kopfstütze 11 auf. Die Kopfstütze 11 umfasst ein oberhalb der Rückenlehne 10 angeordnetes Kopfpolster 12 für die Hinterkopfabstützung eines Sitzbenutzers sowie einen das Kopfpolster tragenden Halter, der in der Rückenlehne 10 höhenverstellbar verankert ist. Der als U-förmige Haltebügel ausgeführte Halter 13 weist zwei im Parallelabstand zueinander verlaufende Haltestangen 14, 15 und eine die beiden Haltestangen 14, 15 an deren einem Ende einstückig miteinander verbindende Querstange 16 auf. Die Haltenstangen 14, 15 sind in bekannter Weise in Führungshülsen, die in der Rückenlehne 10 integriert sind, höhenverstellbar aufgenommen und in jeder Höhenverstellposition in der Rückenlehne 10 verrastbar. Die Hδhenverstellbarkeit des Kopfpolsters 12 ist in Fig. 1 durch den Doppelpfeil 26 symbolisiert. Auf die Darstellung der Hö- henverstellvorrichtung, die allgemein bekannt ist und beispielhaft in der DE 43 05 902 C2 beschrieben ist, ist hier verzichtet worden.The vehicle seat shown in detail in FIG. 1 has, in a known manner, a seat cushion that cannot be seen here, ne on the seat cushion pivotally held back 10 and a headrest 11. The headrest 11 comprises a head cushion 12 arranged above the backrest 10 for supporting the back of the head of a seat user and a holder which supports the head cushion and is anchored in the backrest 10 in a height-adjustable manner. The holder 13, which is designed as a U-shaped holding bracket, has two holding rods 14, 15 which run parallel to one another and a cross rod 16 which integrally connects the two holding rods 14, 15 at one end thereof. The holding rods 14, 15 are accommodated in a known manner in guide sleeves, which are integrated in the backrest 10, in a height-adjustable manner and can be locked in the backrest 10 in any height-adjusting position. The height adjustability of the head cushion 12 is symbolized in FIG. 1 by the double arrow 26. The representation of the height adjustment device, which is generally known and is described by way of example in DE 43 05 902 C2, has been omitted here.
Das Kopfpolster 12 ist einerseits um eine parallel zur Oberkante der Rückenlehne 10 ausgerichtete Schwenkachse 17 (Fig.The head cushion 12 is on the one hand about a pivot axis 17 aligned parallel to the upper edge of the backrest 10 (FIG.
1 und 2) schwenkbar und andererseits in Richtung seiner Schwenkachse 17 längsverschieblich am Halter 13 festgelegt, und zwar auf der Querstange 16 des Halters 13. Die Schwenkbarkeit des Kopfpolsters 12 ist in Fig. 1 durch den Doppelpfeil 27 und die Längsverschiebbarkeit durch dem Doppelpfeil1 and 2) pivotable and on the other hand fixed in the direction of its pivot axis 17 on the holder 13, namely on the crossbar 16 of the holder 13. The pivoting of the head cushion 12 is in Fig. 1 by the double arrow 27 and the longitudinal displacement by the double arrow
28 symbolisiert. Wie die Schnittdarstellungen der Fig. 2 und28 symbolizes. As the sectional views of FIGS. 2 and
3 zeigen, weist das Kopfpolster 12 einen Versteifungskörper 18 sowie eine Polsterung 19 auf, die den Versteifungskörper 18 außen umkleidet. Im Versteifungskörper 18 sind eine Querbohrung 20 sowie seitlich links und rechts je ein Hohlraum 21 ausgebildet, der zur Unterseite des Kopfpolsters 12 hin offen ist. Die beiden Hohlräume 21 sind über die Querbohrung 20 miteinander verbunden, die an jedem Ende jeweils in einem der Hohlräume 21 mündet. In je einen Hohlraum 21 ist eine Haltestange 14 bzw. 15 des Halters 13 von unten eingeführt, und die die beiden Haltestangen 16 verbindende Querstange 16 des Halters 13 erstreckt sich durch die Querbohrung 20 hindurch. Auf der Querstange 16 sitzt mindestens eine Lagerhülse 22, die fest mit dem Versteifungskörper 18 verbunden ist. Die Lagerhülse 22 ist so gestaltet, dass sie auf der Querstange 16 einerseits drehbar und andererseits längsverschiebbar ist . Im Ausführungsbeispiel der Fig. 2 sind zwei im Axialabstand voneinander angeordnete Lagerhülsen 22 auf der Querstange 16 vorgesehen, von denen in Fig. 2 nur die linke Lagerhülse 22 zu sehen ist. Jede Lagerhülse 22 wirkt mit einem Axialanschlag 23 zusammen, der den Verschiebeweg der Lagerhülse 22 und damit den Querverschiebeweg des Kopfpolsters 12 in eine Verschieberichtung begrenzt. Im beschriebenen Ausführungsbei- spiel ist der Axialanschlag 23 als Ringscheibe 24 ausgeführt, die axial unverschieblich auf der Querstange 16 festgelegt ist. Wird das Kopfpolster 12 in Fig. 2 maximal nach links verschoben, so schlägt nach einem Verschiebeweg die ringförmige Stirnfläche der Lagerhülse 22 an der Ringscheibe 24 an, wodurch die weitere Verschiebung des Kopfpolsters 12 in diese Richtung blockiert ist.3 show, the head cushion 12 has a stiffening body 18 and a padding 19 which surrounds the stiffening body 18 on the outside. In the stiffening body 18, a transverse bore 20 and laterally left and right each have a cavity 21 which is open to the underside of the head cushion 12. The two cavities 21 are connected to one another via the transverse bore 20, each of which is in one of the ends at each end Cavities 21 opens out. In each cavity 21, a support rod 14 or 15 of the holder 13 is inserted from below, and the cross rod 16 connecting the two support rods 16 of the holder 13 extends through the transverse bore 20. At least one bearing sleeve 22 is seated on the crossbar 16 and is fixedly connected to the stiffening body 18. The bearing sleeve 22 is designed so that it is rotatable on the crossbar 16 on the one hand and longitudinally displaceable on the other hand. In the exemplary embodiment in FIG. 2, two bearing sleeves 22 arranged at an axial distance from one another are provided on the transverse rod 16, of which only the left bearing sleeve 22 can be seen in FIG. 2. Each bearing sleeve 22 interacts with an axial stop 23, which limits the displacement of the bearing sleeve 22 and thus the transverse displacement of the head cushion 12 in one direction of displacement. In the exemplary embodiment described, the axial stop 23 is designed as an annular disk 24, which is fixed axially immovably on the crossbar 16. If the head cushion 12 is maximally displaced to the left in FIG. 2, the annular end face of the bearing sleeve 22 strikes the annular disk 24 after a displacement path, as a result of which the further displacement of the head cushion 12 in this direction is blocked.
Um einerseits die Hohlräume 21 im Kopfpolster 12 nach unten abzudecken und andererseits die Querverschiebung des Kopfpolsters 12 relativ zu den Haltestangen 16 nicht zu beeinträchtigen, ist jeder Hohlraum 21 von einem Faltenbalg 25 abgedeckt, der einerseits die Haltestange 14 bzw. 15 umschließt und anderseits an der Polsterung 19 an der Unterseite des Kopfpolsters 12 befestigt ist. In Fig. 2 ist lediglich der linke Faltenbalg 25 zu sehen.In order on the one hand to cover the cavities 21 in the head cushion 12 downwards and on the other hand not to impair the transverse displacement of the head cushion 12 relative to the support rods 16, each cavity 21 is covered by a bellows 25 which on the one hand encloses the support rod 14 or 15 and on the other hand on the Padding 19 is attached to the underside of the head cushion 12. Only the left bellows 25 can be seen in FIG. 2.
Bei der beschriebenen Kopfstütze muss die Querverschiebung des Kopfpolsters 12 in Richtung dessen Schwenkachse 17 manu- eil vorgenommen werden. In Fig. 1 ist dabei eine mögliche Querverschiebestellung des Kopfpolsters 12 relativ zu dem in der Kopfstütze 11 festgelegten Halter 13 strichpunktiert angedeutet. Die in Fig. 1 ausgezogen dargestellte Position des Kopfpolsters 12, in der das Kopfpolster 12 mittig zur Rückenlehne 10 ausgerichtet ist, kann eine Rastposition aufweisen, um die normale Gebrauchsstellung des Kopfpolsters 12 mühelos und zuverlässig herzustellen.In the headrest described, the transverse displacement of the head cushion 12 in the direction of its pivot axis 17 must be be made quickly. In Fig. 1, a possible transverse displacement position of the head cushion 12 relative to the holder 13 fixed in the headrest 11 is indicated by dash-dotted lines. The position of the head cushion 12 shown in solid lines in FIG. 1, in which the head cushion 12 is aligned centrally to the backrest 10, can have a latching position in order to produce the normal use position of the head cushion 12 effortlessly and reliably.
Selbstverständlich ist es auch möglich, die Querverschiebung des Kopfpolsters 12 motorisch, z.B. durch einen elektrischen Stellmotor, vorzunehmen. Auch eine pneumatische oder hydraulische Querverschiebung des Kopfpolsters 12, die vom Sitzbenutzer über einen Stellknopf ausgelöst wird, ist möglich.Of course, it is also possible to motorize the transverse displacement of the head cushion 12, e.g. by an electric servomotor. A pneumatic or hydraulic transverse displacement of the head cushion 12, which is triggered by the seat user via an adjusting button, is also possible.
Die beschriebene Kopfstütze, deren Kopfpolster 12 einerseits höhenverstellbar, andererseits querverschiebbar und um die Verschiebeachse schwenkbar ausgebildet ist kann zusätzlich noch so ausgebildet werden, dass sie in Richtung Sitztiefe, also senkrecht zu ihrer Schwenkachse 17 verschiebbar ist, so dass sie zusätzlich noch näher an den Hinterkopf des Sitzenden herangeführt oder vom Hinterkopf etwas weggenommen werden kann. Eine solche zusätzliche Verstellmöglichkeit des Kopf- polsters 12 in Richtung Sitztiefe ist in der eingangs zitierten DE 43 05 909 C2 beschrieben. The described headrest, the head cushion 12 of which is on the one hand height-adjustable, on the other hand can be displaced transversely and pivoted about the displacement axis, can also be designed such that it can be displaced in the direction of the seat depth, that is to say perpendicular to its pivot axis 17, so that it is additionally closer to the back of the head of the seated person or something can be removed from the back of the head. Such an additional possibility of adjusting the head cushion 12 in the direction of the seat depth is described in DE 43 05 909 C2 cited at the beginning.
