Die
Der Erfindung liegt die Aufgabe zu Grunde, eine Kopfstütze der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Kopfstütze mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, a headrest of to improve the type mentioned above. This object is achieved by a headrest solved with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
Dadurch, daß das Prallelement ein Halteelement aufweist und daß eine schwenkbare, unbelastete Klinke in einer schließenden Stellung das Halteelement hält, im Crashfall freigibt und nach dem Crashfall für einen Reset der Kopfstütze in jeder ihrer möglichen Stellungen für das Halteelement aufnahmebereit ist, steht eine einfache Sicherung oder Verriegelung des Prallelementes für den Normalfall zur Verfügung, die mit wenigen Bauteilen auskommt. Der Reset der Kopfstütze nach einem Crash ermöglicht einen erneuten Einsatz der Kopfstütze, was Material- und Werkstattkosten spart. Durch die – in einem gewissen Bereich – freie Bewegungs möglichkeit der Klinke können Mittel für eine definierte Stellung der Klinke, beispielsweise eine vorspannende Feder oder dergleichen, entfallen, was die Herstellungskosten senkt. Die Aufnahmebereitschaft wird durch die Geometrie der Klinke gewährleistet. So weist die Klinke vorzugsweise eine Anlaufschräge auf, an welche das anlaufende Halteelement in wenigstens einer Stellung der Klinke in Anlage gelangt. Durch die schräge Fläche dreht das Halteelement die Klinke und öffnet sie dabei, so daß das Halteelement in das Klinkenmaul gelangen kann. Das Klinkenmaul weist vorzugsweise eine Lippe auf, an welche das anlaufende Halteelement in wenigstens einer Stellung der Klinke, die dann bereits geöffnet ist, auch direkt in Anlage gelangen kann, um in das Klinkenmaul zu gelangen. Vorzugsweise wird die frei bewegliche Klinke normalerweise, d.h. beim Normalgebrauch der Kopfstütze, durch einen mittels eines Magneten gehaltenen Steuerhebel in ihrer schließenden Stellung gehalten.Thereby, that this Baffle element has a holding element and that a pivotable, unloaded Latch in a closing Position holding the holding element, releases in the event of a crash and after the crash for a reset of the headrest in each their possible Positions for the holding element is receptive, is a simple backup or locking the baffle element for the normal case available, the works with few components. The reset of the headrest after a crash allows one reuse of the headrest, which saves material and workshop costs. By - in one certain area - free Movement possibility the latch can Funds for a defined position of the pawl, for example, a biasing Spring or the like, eliminated, which reduces the cost. The receptivity is ensured by the geometry of the pawl. Thus, the latch preferably has a run-on slope, to which the incoming Retaining element comes into abutment in at least one position of the pawl. By the oblique area the holding element rotates the pawl and opens it, so that the holding element can get into the jaw mouth. The jack mouth preferably a lip, to which the starting holding element in at least a position of the pawl, which is then already open, also directly in Appendix can reach to get into the jaw mouth. Preferably the free-moving latch normally, i. in normal use the headrest, by a held by a magnet control lever in their closing Held position.
Das Halteelement ist vorzugsweise weiträumig in das Prallelement eingelagert, um eine großflächige Kraftübertragung und damit geringe Flächenpressungen zu gewährleisten. So weist das Prallelement vorzugsweise eine Aufnahme für das Halteelement auf, in welche das Halteelement – vorzugsweise mit einem abgekröpften Mittelbereich – formschlüssig einlegbar ist und welche durch einen Deckel schließbar ist. Der vorzugsweise als Feder ausgebildete Energiespeicher beaufschlagt das vorzugsweise metallisch ausgebildete das Halteelement vorzugsweise direkt, so daß auch keine hohen Flächenpressungen zwischen Metall und Kunststoff auftreten.The Retaining element is preferably stored over a wide area in the impact element, a large-scale power transmission and thus low surface pressures to ensure. Thus, the baffle preferably has a receptacle for the holding element in which the holding element - preferably with a cranked central region - positively inserted is and which can be closed by a lid. The preferably designed as a spring energy storage acts on the preferably metallic formed the holding element preferably directly, so that too no high surface pressures between metal and plastic occur.
Durch obere und untere Schwingen, welche eine von der Parallelität abweichende Ausrichtung zueinander einnehmen, also durch ein von der Parallelogrammform abweichendes Viergelenk, wird das System der Kopfstütze stabilisiert. Dadurch wird in der Ausgangsstellung ein Totpunkt im Viergelenk vermieden, welcher das Ausfahren im Crashfall erschweren könnte. Des weiteren kann der bei Kräften von vorne oder von oben auf die Schwingen wirkende relevante Hebelarm kurz gehalten werden. Schließlich kann auch ein günstigerer Auffangwinkel erreicht werden. Erreicht wird dies alles vorzugsweise durch unterschiedliche Längen der Schwingen, beispielsweise indem die unteren Schwingen länger als die oberen Schwingen sind, soweit es die Abstände der Gelenke im Viergelenk betrifft. Die langen unteren Schwingen haben noch den Vorteil, daß beim Ausfahren des Viergelenks das auf dem Prallelement vorgesehene Polsterteil sich weitgehend tangential in Fahrtrichtung nach vorne bewegt, was eine einfachere Verblendung erlaubt und Kollisionen im unteren Bereich verhindert.By upper and lower wings, which deviate from the parallelism Take alignment with each other, so by one of the Parallelogrammform deviating four-joint, the system of the headrest is stabilized. As a result, in the initial position, a dead center in the four-bar linkage avoided, which could complicate the extension in the event of a crash. Of another can at the forces of Relevant lever arm acting on the wings at the front or from above be kept short. After all can also be a cheaper Falling angle can be achieved. This is achieved all preferably through different lengths the swinging, for example by the lower wings longer than the upper wings are, as far as the distances of the joints in the four-joint concerns. The long lower wings still have the advantage that when extending of the four-bar link provided on the baffle padding moves largely tangentially forward in the direction of travel, which allows easier veneering and collisions at the bottom prevented.
Mehrere Crashstellungen, die dann durch eine Crashsperre jeweils nach hinten gesperrt sind, haben den Vorteil, daß im Crashfall das sich vorwärts bewegende Prallelement unmittelbar nach Kontakt mit dem sich nach hinten bewegenden Kopf des Insassens gesperrt werden kann. Der Kopf wird dann möglichst weit vorne aufgefangen und erhält keinen zusätzlichen Impuls durch eine ungebremste Kopfstütze. Dies verhindert zusätzliche Belastungen für den Insassen. Für eine einfache und kostengünstige Realisierung einer solchen Crashsperre ist in bevorzugter Ausführung am Träger ein wenigstens teilweise bewegliches Crashsperrenteil und an wenigstens einer der Schwingen oder einem zusammen mit den Schwingen bewegten Bauteil eine Crashsperrenverzahnung vorgesehen, welche in jeder Crashstellung mit dem Crashsperrenteil zusammenwirkt, wobei beispielsweise durch mehrere Zähne mehrere Crashsteilungen definiert werden. Durch eine Art Sägezahnform wird die Sperrwirkung auf eine Richtung beschränkt, d.h. die Vorwärtsbewegung des Prallelementes wird nicht behindert. Um die Crashsperre wieder zu öffnen, kann beispielsweise am Crashsperrenteil eine Drucktaste vorgesehen sein.Several crash positions, which are then locked by a crash barrier in each case to the rear, have the advantage that in the event of a crash, the forward moving baffle element can be locked immediately after contact with the head of the occupant moving backwards. The head is then caught as far forward and receives no additional impulse through an unchecked headrest. This prevents additional stress for the occupant. For a simple and cost-effective implementation of such a crash barrier is in a preferred embodiment on the support an at least partially movable crash lock part and at least one of the rockers or a moving together with the rocking member a crash barrier toothing provided, which cooperates with the crash barrier part in each crash position, for example by several teeth several crashes be defined. By a kind of sawtooth shape, the blocking effect is limited to one direction, ie the forward movement of the baffle element is not hindered. To reopen the crash barrier, a pushbutton can be provided, for example, on the crash barrier part.
