Description
Die Erfindung betrifft eine Kopfstütze für Kraftfahrzeugsitze gemäß Oberbegriff der Ansprüche 1 und 2.The The invention relates to a headrest for motor vehicle seats according to the generic term of claims 1 and 2.
Eine der häufigsten Verletzungen im täglichen Straßenverkehr sind Nackenverletzungen eines Fahrzeuginsassen in Folge eines so genannten Peitschenschlages seines Kopfes bei einem Heck-Crash. Um solche Verletzungen zu vermeiden bzw. zu vermindern sind Kraftfahrzeugsitze mit so genannten heckcrashaktiven Kopfstützen entwickelt worden. Bei diesen Sitzen wird die bei einem Heck-Crash auf die Rückenlehne des Kraftfahrzeugsitzes wirkende Trägheitskraft des Körpers eines Sitzinsassen durch entsprechende Übertragungsmechanismen derart auf die Kopfstütze übertragen, dass diese sich nach vorn zum Kopf des Sitzinsassen hin bewegt. Dadurch wird dem so genannten Peitschenschlag des Kopfes des Sitzinsassen entgegengewirkt.A the most common Injuries in the daily road traffic are neck injuries of a vehicle occupant as a result of so called whiplash of his head in a rear-crash. To avoid or reduce such injuries are motor vehicle seats developed with so-called rear crash-active headrests. at These seats will be in a rear crash on the backrest the vehicle seat acting inertial force of the body of a Seat occupants by appropriate transmission mechanisms such transferred to the headrest that this moves forward towards the seat occupant's head. Thereby becomes the so-called lash of the head of the seat occupant counteracted.
