Die Aufgabe der vorliegenden Erfindung besteht darin, einen Fahrzeugsitz der eingangs genannten Art so auszubilden, dass mit relativ einfachen konstruktiven Mitteln die Belastung eines Fahrzeuginsassen durch einen Heckcrash minimiert und damit die Rückhaltefunktion des Fahrzeugsitzes bei einem Heckcrash optimiert wird.The The object of the present invention is a vehicle seat of the type mentioned above in such a way that with relatively simple constructive means the burden of a vehicle occupant minimizes a rear crash and thus the retention function of the vehicle seat is optimized in a rear-end crash.
Vorteilhafte und zweckmäßige Weiterbildungen der Aufgabenlösung sind in den Unteransprüchen angegeben.advantageous and appropriate training the task solution are in the subclaims specified.
Die Erfindung schlägt eine Deformationsvorrichtung vor, die bei Überschreitung eines vorgebbaren Beschleunigungsschwellwertes anspricht und den Lehnenrahmen zunächst in eine translatorische und dann in eine rotatorische Bewegung versetzt. Hierdurch wird die durch einen Heckcrash in die Rückenlehne des Fahrzeugsitzes eingetragene Energie weitestgehend abgebaut und somit die Belastung des Fahrzeuginsassen erheblich verringert.The Invention proposes a deformation device which, when exceeding a predefinable Acceleration threshold responds and the back frame initially in a translatory and then put into a rotational movement. hereby is due to a rear crash in the backrest of the vehicle seat enlisted energy degraded as much as possible and thus the burden of Vehicle occupants significantly reduced.
Die
Deformationsvorrichtung wird vorteilhafterweise durch zwei im Lehnenrahmen
bzw. an der Lehnenverstelleinrichtung oder im Sitzadapter (
Gemäß einer vorteilhaften Weiterbildung der Erfindung sind die beiden Langlöcher in Fahrtrichtung hintereinander angeordnet, wobei das in Fahrtrichtung vordere Langloch in Fahrtrichtung gerade verlaufend und das in Fahrtrichtung hintere Langloch bogenförmig oder winkelförmig ausgebildet ist. Das bogenförmige oder winkelförmige Langloch weist in weiterer vorteilhafter Ausgestaltung der Erfindung einen ersten, in Richtung des vorderen geraden Langlochs verlaufenden Abschnitt für eine translatorische Bewegungsphase des Lehnenrahmens bzw. der Lehnenverstelleinrichtung und einen sich darin nach vorn in Fahrtrichtung anschließenden abgebogenen oder abgewinkelten, zweiten Abschnitt für eine sich der translatorischen Bewegungsphase anschließende rotatorische Bewegungsphase des Lehnenrahmens bzw. der Lehnenverstelleinrichtung relativ zum Sitzadapter auf, wobei der Lehnenrahmen bzw. die Lehnenverstelleinrichtung relativ zum Sitzadapter nach hinten verschwenkt.According to an advantageous embodiment of the invention, the two slots are arranged one behind the other in the direction of travel, wherein the front in the direction of travel elongated hole in the direction of travel straight and the rear in the direction of travel slot is arcuate or angular. The arcuate or angular slot has in a further advantageous embodiment of the invention, a first, extending in the direction of the front straight slot portion for a translational movement phase of the back frame or Lehnenverstelleinrichtung and a subsequent forward in the direction of travel bent or angled, second section for a the translational movement phase subsequent rotational movement phase of the backrest frame or the Lehnenverstelleinrichtung relative to the seat adapter, wherein the back frame or the Lehnenverstelleinrichtung pivoted relative to the seat adapter to the rear.
Zur Erzielung der Verschwenkung des Lehnenrahmens bzw. der Lehnenverstelleinrichtung relativ zum Sitzadapter in der rotatorischen Bewegungsphase ist der abgebogene oder abgewinkelte, zweite Abschnitt des hinteren Langlochs in Fahrtrichtung schräg nach oben verlaufend ausgebildet.to Achieving the pivoting of the backrest frame or Lehnenverstelleinrichtung relative to the seat adapter in the rotational movement phase the bent or angled, second section of the rear Oblong hole in direction of travel oblique designed to extend upward.
Der Deformationswiderstand der Deformationsvorrichtung ist durch Wahl des Verhältnisses Schraubbolzendurchmesser/Langlochbreite einstellbar, wodurch der Beschleunigungsschwellwert voreinstellbar ist.Of the Deformation resistance of the deformation device is by choice the ratio bolt diameter / slot width adjustable, whereby the acceleration threshold can be preset is.
Eine weitere Möglichkeit den Beschleunigungsschwellwert zu beeinflussen besteht über die Wahl des Drehmomentes des in den Langlöchern verschiebbaren, in den Sitzadapter oder in die Lehnenverstelleinrichtung einschraubbaren Schraubbolzens.A another possibility to influence the acceleration threshold exists over the choice the torque of slidable in the slots, in the Seat adapter or in the Lehnenverstelleinrichtung screwed Bolt.
