Description
Die Erfindung betrifft eine aktive Kopfstütze, insbesondere für einen Kraftfahrzeugsitz, welche durch eine bei einem Frontal- bzw. Heckaufprall auslösbare Antriebseinrichtung zumindest in der Höhe verstellbar ist, wobei die Kopfstütze ein die Abstützfläche für den Kopf eines Sitzbenutzers bildendes Polsterteil sowie eine das Polsterteil in der jeweiligen Stützposition haltende Trageinrichtung aufweist, die durch zumindest eine Tragstange mit der Rückenlehne verbunden ist.The The invention relates to an active headrest, in particular for a Motor vehicle seat, which by a in a frontal or rear impact releasable Drive device is adjustable at least in height, wherein the headrest a the support surface for the head a seat occupant forming upholstery and a padded part in the respective support position holding carrying device, by at least one support rod with the backrest connected is.
Es sind aktive Kopfstützen bekannt, bei denen das Stützkissen zur Abstützung des Kopfes eines Insassen in seiner vertikalen Ausdehnung veränderbar ausgebildet ist. Insbesondere ist das Stützkissen in vertikalen Richtung, bevorzugt schräg nach vorne und oben, teleskopierbar ausgebildet, so daß bei einem Unfall eine teleskopierte Kopfstütze erreicht wird, welche eine Nachhintenbewegung des Kopfes über die obere Stützkissenkante verhindert.It are active headrests known where the support pillow for support the head of an occupant in its vertical extent changeable is trained. In particular, the support cushion is in the vertical direction, preferably obliquely forward and upward, telescopically formed, so that at a Accident a telescoped headrest is reached, which a Nachhintenbewegung of the head over the upper support cushion edge prevented.
Bei dieser Lösung besteht das Stützkissen aus zumindest zwei in vertikaler Richtung zueinander beweglichen Kissenteilen, wobei zumindest eines der Kissenteile mit der Antriebskraft eines Kraftspeichers (Antriebseinrichtung) beaufschlagbar ist. Eine derartige Kopfstütze ist jedoch kompliziert im Aufbau sowie umständlich in der Handhabung, da der Kraftspeicher innerhalb der Kopfstütze bzw. der Kissenteile angeordnet ist, welche lediglich über Stützeinrichtungen (Tragstangen) mit der Rückenlehne verbunden sind.at this solution the support pillow is made out at least two vertically movable pad parts, wherein at least one of the cushion parts with the driving force of a Force accumulator (drive device) can be acted upon. Such headrest However, it is complicated in construction and cumbersome to use, since arranged the energy storage within the headrest or the cushion parts which is just over support devices (Support bars) with the backrest are connected.

weitere Lösung
zur Erhöhung
der Sicherheit des Insassen geht aus der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Sicherheit und den Bedienungskomfort für den Benutzer eines Kraftfahrzeugsitzes mit der eingangs genannten Kopfstütze mit einfachen Mitteln noch weiter zu erhöhen.Of the The present invention is based on the object of safety and the ease of use for the user of a motor vehicle seat with the aforementioned headrest to increase even further with simple means.
Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 erfindungsgemäß dadurch gelöst, dass die Antriebseinrichtung einen sich etwa im Bereich zwischen der Rückenlehne und der Kopfstütze bzw. dem Polsterteil entfaltenden Airbag aufweist.These Task becomes in connection with the characteristics of the generic term of the Patent claim 1 according to the invention thereby solved, that the drive device extends approximately in the area between the backrest and the headrest or the cushion part unfolding airbag.
Wesentliche Vorteile dieser Ausbildung bestehen darin, dass die Kopfstütze im Falle eines Frontal- bzw. Heckaufpralls durch die Antriebseinrichtung derart in der Höhe verstellt wird, dass eine sichere Abstützung des Kopfes sowohl bei einem großen als auch bei einem kleinen Sitzbenutzer gewährleistet ist.basics Advantages of this training are that the headrest in the case a frontal or rear impact by the drive device so in height it is adjusted that a secure support of the head both at a big one as well as a small seat user is guaranteed.
Für eine derartige aktive Verstellung der Kopfstütze ist gemäß der Erfindung eine im oberen Bereich der Rückenlehne angeordnete Antriebseinrichtung mit einem im Spalt zwischen der Kopfstütze und der Rückenlehne aufblasbaren Airbag vorgesehen, welche bei Aktivierung, beispielsweise durch eine zentrale Airbag-Steuerung, die Kopfstütze zumindest nach oben verstellt.For such active adjustment of the headrest is according to the invention one at the top of the backrest arranged drive means with a in the gap between the Headrest and the backrest inflatable airbag provided, which when activated, for example by a central airbag control, the headrest at least moved upwards.
Durch die aktive Verstellung wird die Abstützfläche der Kopfstütze in eine Position gebracht, in der eine etwa gleichzeitige Abstützung des Sitzbenutzers sowohl an der Rückenlehne als auch an der Kopfstütze stattfinden kann. Eine gefährliche Krümmung bzw. Überbelastung der Halswir belsäule des Sitzbenutzers beim Heckaufprall bzw. einem Zurückschleudern in den Kraftfahrzeugsitz nach beispielsweise einem Frontalaufprall wird durch diese Verstellung der Kopfstütze vermieden.By The active adjustment becomes the support surface of the headrest in one Positioned in an approximately simultaneous support of the Seat occupant both on the backrest as well as on the headrest can take place. A dangerous one curvature or overloading the cervical spine of the seat occupant during the rear impact or a spin-back in the motor vehicle seat after, for example, a frontal impact is avoided by this adjustment of the headrest.
Die aktive Verstellung der Kopfstütze erfolgt unabhängig von der in der Höhe bzw. in der Neigung eingestellten Position der Kopfstütze. Nach der Auslösung der Antriebseinrichtung wird somit eine sichere Anlage (Abstützung) des Kopfes des Sitzbenutzers auch bei einer versehentlich nicht richtig oder zu niedrig eingestellten Kopfstütze erreicht. Da gleichzeitig zwischen der nach oben bewegten Kopfstütze und der Oberkante der Rückenlehne eine zusätzliche Abstützfläche gebildet wird, werden auch mögliche Verletzungen durch Trageinrichtungen der Kopfstütze, wie beispielsweise Tragstangen, vermieden.The active adjustment of the headrest takes place independently from the height or tilted position of the headrest. To the trigger The drive device is thus a safe system (support) of the Head of the seat occupant even if accidentally not correct or headrest set too low. At the same time between the upwardly moving headrest and the top edge of the backrest formed an additional support surface will be possible injuries by support means of the headrest, such as support bars, avoided.
Ein weiterer Vorteil der vorgeschlagenen Ausführung besteht darin, daß die Kopfstütze bei einer Verstellung nach oben derart verriegelbar ausgebildet ist, daß eine zusätzliche Aufnahme von etwa in vertikaler Richtung wirkenden Kräften, beispielsweise bei einem nachfolgenden Überschlag des Kraftfahrzeuges, durch die Kopfstütze möglich ist.Another advantage of the proposed embodiment is that the headrest is formed locked in an upward adjustment so that an additional recording of about in vertical direction acting forces, for example, in a subsequent rollover of the motor vehicle, by the headrest is possible.
