Description
Die Erfindung betrifft eine Kopfstütze für Fahrzeugsitze nach dem Oberbegriff des Hauptanspruchs.The invention relates to a headrest for vehicle seats according to the preamble of the main claim.
Aus der DE-OS 33 42 460 ist eine Kopfstütze für Fahrzeug sitze bekannt, deren Kopfstützenpolster entlang der Schenkel eines U-förmigen Rahmens höhenverstellbar und an diesen festlegbar ist. Um eine derartige Kopfstütze unfallsicher zu gestalten, muß der Rahmen, der die in das Kopfstützenpolster eingeleiteten Aufprallkräfte abstützt, besonders widerstandsfähig gebaut sein. Dies bedingt für die Werkstoffauswahl und die Bearbeitungsqualität des Rahmens einen nicht unerheblichen Aufwand.DE-OS 33 42 460 is a headrest for a vehicle known seats, the headrest pads along the Leg of a U-shaped frame adjustable in height and on this can be determined. To such a headrest To make it accident-proof, the framework that forms part of the The headrest cushion supports the impact forces introduced, be built to be particularly robust. This requires for the material selection and the processing quality of the Framework a not inconsiderable effort.
In der DE-OS 25 45 840 ist eine Überrollstütze be schrieben, die aus einer Stützkonstruktion besteht, die in die Rückenlehne eines Fahrzeugsitzes eingebaut ist, an welche eine in die Stützkonstruktion integrierte Kopf stütze anschließt. Ein derartiger, durch die Stützkon struktion gebildeter Rahmen bietet keine Variationsmög lichkeit in der Anordnung der Kopfstütze und auch keine Höhenverstellung des Kopfstützenpolsters zur günstigsten Anpassung des Kopfstützenpolsters an die Größe einer dort sitzenden Person. Außerdem kann eine Überrollstütze, die mit der Lehnenverstellung ihre Neigung verändern muß, nicht als optimale Abstützung für das Fahrzeug und für das daran befestigte Kopfstützenpolster angesehen werden.In DE-OS 25 45 840 a roll support is wrote, which consists of a support structure that in the backrest of a vehicle seat is installed which is a head integrated into the support structure support connects. Such, by the support con The structure of the frame does not offer any variation in the arrangement of the headrest and none Height adjustment of the headrest cushion at the cheapest Adjustment of the headrest cushion to the size of one there seated person. In addition, a roll support that must change their inclination with the backrest adjustment, not as optimal support for the vehicle and for that headrest pads attached to it can be viewed.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungs gemäße Kopfstütze herstellungsgünstig und dennoch unfall sicher zu verwirklichen.The invention has for its object a genus appropriate headrest cheap to manufacture and still an accident to implement safely.
Die Aufgabe wird durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst.The task is characterized by the characteristics of the Main claim solved.
An einen in einem Fahrzeug vorhandenen Überrollbügel werden höchste Sicherheitsansprüche gegen ein Nachgeben unter Belastung gestellt. Wird nun den einzelnen Fahr zeugsitzen jeweils für sich ein U-förmiger Überrollbügel zugeordnet, und dieser hinter dem Sitz am Fahrzeugboden abgestützt, so ergibt dieser Rahmen für das Kopfstützen polster eine besonders sichere Lagermöglichkeit.On a roll bar present in a vehicle are the highest security requirements against yielding put under stress. Now the individual driving each have a U-shaped roll bar assigned, and this behind the seat on the vehicle floor supported, this results in a frame for the headrests upholstery is a particularly safe storage option.
Eine Höhenverstellung des Kopfstützenpolsters kann einer seits durch eine Verschiebung des U-förmigen Überroll bügels in den Führungen seiner Schenkel und andererseits durch eine Verschiebung des Kopfstützenpolsters entlang der Schenkel des Überrollbügels erfolgen. One can adjust the height of the headrest cushion partly by shifting the U-shaped rollover bracket in the guides of his legs and on the other by moving the headrest cushion along the legs of the roll bar are made.
Dabei ist für jede neu eingenommene Einstellposition in bekannter Weise eine Verriegelung gegen weiteres Ver schieben vorzusehen.It is in for each newly set position known way a lock against further Ver push to provide.
Ein Sicherheitsoptimum wird erreicht, wenn der quer verlaufende Steg des Überrollbügels bei jeder Anpassung der Höhe des Kopfstützenpolsters an eine sitzende Person mit diesem mitverschoben wird und jeweils hinter der Aufprallfläche des Kopfstützenpolsters verbleibt, so daß dieses durch den Überrollbügel eine Verstärkung bei Belastung in Fahrzeuglängsrichtung erfährt. Um dies zu erreichen, werden für den Überrollbügel und das Kopf stützenpolster unabhängig voneinander regelbare Antriebe vorgesehen, damit der Überrollbügel bei einem Crash rasch in seine höchste Position austreibbar ist, während das Kopfstützenpolster in seiner eingestellten Lage abgestützt verbleibt. Diese Abstützung kann durch den Antrieb selbst oder auch durch eine unabhängig steuerbare Arretierung für das Kopfstützenpolster erfolgen.A safety optimum is achieved when the cross running bar of the roll bar with every adjustment the height of the headrest cushion to a seated person is moved with this and behind each Impact surface of the headrest cushion remains so that this is reinforced by the roll bar Experienced load in the vehicle longitudinal direction. To do this reach for the roll bar and the head support pads independently controllable drives provided so that the roll bar quickly in a crash can be driven out into its highest position while the Headrest cushion supported in its set position remains. This support can be done by the drive itself or also by an independently controllable lock for the headrest pads are made.
Bei einer derart individuellen Einstellmöglichkeit der Höhe des Kopfstützenpolsters bietet es sich an, in das Kopfstützenpolster eine obere Umlenkung für den Sicher heitsgurt zu integrieren, so daß mit der Polsterverstel lung automatisch auch eine passende Höheneinstellung des oberen Gurtumlenkpunkts erfolgt.With such an individual setting option Height of the headrest cushion offers itself in that Headrest cushion an upper deflection for the safe integrate the seat belt so that with the cushion adjuster suitable height adjustment of the upper belt deflection point.
Die Gegenstände weiterer Ansprüche bilden weitere vor
teilhafte Ausgestaltungsmöglichkeiten.
The subjects of further claims form further before partial design options.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is in the drawing shown.
Die Fig. 1 und 2 zeigen in einer Seiten- und in einer Rückansicht eine Kopfstütze für einen Fahrzeugsitz mit einem an einem Überrollbügel festgelegten Kopfstützenpol ster, mit mehreren Darstellungen einstellbarer Höhen des Kopfstützenpolsters und des Überrollbügels. Figs. 1 and 2 show in a side and a rear view of a headrest for a vehicle seat with a fixed on a roll bar Kopfstützenpol art, with adjustable heights several views of the headrest cushion and of the roll bar.
In einem Kraftwagen ist hinter einem Fahrzeugsitz 1 ein Überrollbügel 2 abgestützt, der durch ein U-förmig gebo genes Rohr gebildet ist und bei einem Überschlag des Fahrzeugs eine auf dem Sitz 1 sitzende Person derart überragt, daß diese Person z.B. vor dem Eindrücken des Daches in deren Kopfbereich geschützt wird.In a motor vehicle, a rollover bar 2 is behind a vehicle seat 1 is supported, the shape of U-gebo by a genes tube is formed and a person sitting on the seat 1 person surmounted in a rollover of the vehicle such that that person, for example, prior to injection of the roof in whose head area is protected.
Der Überrollbügel 2 dient erfindungsgemäß zusätzlich als Rahmen 3, der zur Festlegung eines in seiner Höhe ein stellbaren Kopfstützenpolsters 4 geeignet ist.The roll bar 2 is also used according to the invention as a frame 3 , which is suitable for fixing an adjustable headrest cushion 4 in height.
Diese Höhenverstellung des Kopfstützenpolsters 4 kann z.B. realisiert werden, wenn der Überrollbügel 2 geradlinig höhenverschiebbar ist und einen Verstellbereich umfaßt, mit dem das Kopfstützenpolster 4 in alle gewünschten Positionen transportierbar ist.This height adjustment of the headrest cushion 4 can be realized, for example, if the roll bar 2 can be shifted in height in a straight line and includes an adjustment range with which the headrest cushion 4 can be transported to all desired positions.
Im gezeigten Ausführungsbeispiel ist das Kopfstützenpol ster 4 entlang der Schenkel 5, 6 des Überrollbügels 2 höhenverschiebbar. In the exemplary embodiment shown, the headrest pole 4 is vertically displaceable along the legs 5 , 6 of the roll bar 2 .
Das Kopfstützenpolster 4 weist in bekannter Weise einen stabilen Innenkörper und einen weichgepolsterten Überzug auf und lagert zwei Hülsenstücke 7, 8 im selben Abstand, den die Schenkel 5, 6 des U-förmigen Überrollbügels 2 einnehmen, so daß das Kopfstützenpolster 4 mit den Hül senstücken 7, 8 auf die Schenkel 5, 6 aufschiebbar und entlang diesen verschiebbar ist. Diese Höheneinstellung wird durch einen regelbaren Antrieb 9 vorgenommen, der hier in stark vereinfachter Abbildung durch ein auf eine Zahnstange 10 an einem Hülsenstück 7 wirkendes Zahnrad 11 dargestellt ist. Die Festlegung des Kopfstützenpolsters 4 nach jedem Verschiebevorgang wird entweder durch bekannte, steuerbare Arretierungen oder aber durch einen Antrieb mit einem selbsthemmenden Getriebe verwirklicht.The headrest cushion 4 has a stable inner body and a soft-padded cover in a known manner and supports two sleeve pieces 7 , 8 at the same distance that the legs 5 , 6 of the U-shaped roll bar 2 occupy, so that the headrest cushion 4 with the sleeve pieces 7 , 8 can be pushed onto the legs 5 , 6 and moved along these. This height adjustment is made by a controllable drive 9 , which is shown here in a highly simplified illustration by a gear 11 acting on a rack 10 on a sleeve piece 7 . The fixation of the headrest cushion 4 after each shifting process is realized either by known, controllable detents or by a drive with a self-locking gear.
Darüber hinaus ist hier auch der Überrollbügel 2 in Führungen 12, 13 seiner Schenkel 5, 6 verschiebbar und durch einen regelbaren Antrieb 14, wie z.B. durch ein Zahnrad 15, das auf eine Zahnstange 16 am Schenkel 5 wirkt, in verschiedene Positionen steuerbar. Dadurch wird erreicht, daß ein quer verlaufender Steg 17 des Überroll bügels 2 bei jeder Anpassung der Höhe des Kopfstützenpol sters 4 an die Größe einer sitzenden Person jeweils hinter einer Aufprallfläche 18 des Kopfstützenpolsters 4 ver bleiben kann, und dieses dadurch bei Belastung in Fahr zeuglängsrichtung zusätzlich stützt.In addition, the roll bar 2 is also displaceable in guides 12 , 13 of its legs 5 , 6 and can be controlled in various positions by a controllable drive 14 , such as, for example, a gear wheel 15 , which acts on a rack 16 on the leg 5 . This ensures that a transverse web 17 of the roll bar 2 with each adjustment of the height of the headrest pole sters 4 to the size of a seated person can stay behind an impact surface 18 of the headrest cushion 4 ver, and this thereby also under load longitudinally driving direction supports.
Damit der Überrollbügel 2 bei einem sich anbahnenden Überschlag des Fahrzeugs in seine schützende, am höchsten ausgefahrene Position 19 überführt werden kann, ist dessen regelbarer Antrieb 14 durch einen Crash-Impuls aus seiner Wirkstellung auskuppelbar, wonach ein nicht näher darge stelltes Feder-Dämpfer-System 23 den Überrollbügel 2 rasch ausfährt, und dieser wiederum arretierbar ist.So that the roll bar 2 can be transferred to its protective, highest extended position 19 when the vehicle is about to roll over, its controllable drive 14 can be disengaged from its active position by a crash pulse, after which a spring-damper system, not shown in more detail 23 the roll bar 2 extends quickly, and this in turn can be locked.
Im Kopfstützenpolster 4 ist seitlich eine obere Umlenkung 20 für einen Sicherheitsgurt 21 festgelegt, deren Höhe dadurch ebenfalls automatisch an die Körpergröße ver schiedener Personen anpaßbar ist.In the headrest cushion 4 , an upper deflection 20 is fixed laterally for a seat belt 21 , the height of which can also be automatically adjusted to the size of different people.
In seiner abgesenktesten Lage schließt das Kopfstützen polster 4 direkt an ein Lehnenteil 22 des Fahrzeugsitzes 1 an, so daß auch für kleine Personen eine angenehme und verletzungssichere Anlehnmöglichkeit gegeben ist.In its most lowered position, the headrest cushion 4 connects directly to a backrest part 22 of the vehicle seat 1 , so that even for small people there is a pleasant and injury-proof leaning possibility.
