Description
Die
Erfindung betrifft eine Rückenlehne
nach dem Oberbegriff von Patentanspruch 1 des Hauptpatents
Als sensorgesteuerter Antrieb für die, Arretiervorrichtung ist beim Hauptpatent ein pyrotechnisches Antriebselement vorgesehen. Derartige Antriebselemente reagieren im Crashfall zwar schnell, sie sind jedoch aufwendig und teuer.When sensor-controlled drive for the, locking device is a pyrotechnic in the main patent Drive element provided. Such drive elements react Although fast in the event of a crash, they are complex and expensive.
Der Erfindung liegt die Aufgabe zugrunde, einen einfachen trägheitssensitiven, direkten Antrieb für die Arretiervorrichtung zu schaffen.Of the Invention is based on the object, a simple inertia-sensitive, direct drive for to provide the locking device.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.The solution This object is achieved with the features of claim 1.
Im normalen Gebrauchszustand ist die Kopfstütze starr mit der Tragstruktur der Rückenlehne verbunden. Die Arretierung der Halterung kann dabei große Kräfte aufnehmen, ohne das die Reaktionsgeschwindigkeit im Crashfall gemindert wird.in the normal state of use, the headrest is rigid with the support structure connected to the backrest. The locking of the holder can absorb large forces, without the Reaction speed is reduced in the event of a crash.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.preferred Embodiments of the invention will become apparent from the dependent claims.
Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:below becomes a preferred embodiment of the invention with reference to the drawings described in detail. It demonstrate:
