Abstract
Description
Die vorliegende Erfindung betrifft einen Kraftfahrzeugsitz mit einem auf vorderen und hinteren Lenker höhenverstellbar gelagerten Sitzteil gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a motor vehicle seat with a on the front and rear handlebar height adjustable mounted seat part according to the generic term of claim 1.
An Höhenverstellvorrichtungen von Kraftfahrzeugsitzen werden hohe Sicherheitsanforderungen gestellt, da auf diese im Crashfall sehr hohe Belastungen wirken, die zu unerwünscht großen Sitzverlagerungen führen können, wodurch das Verletzungsrisiko von Fahrzeuginsassen erhöht wird. Dabei ist es besonders problematisch, wenn bei einem Heckcrash der Kraftfahrzeugsitz bei hoher Einstellung nach hinten schlägt.At height adjustment devices motor vehicle seats are subject to high safety requirements Since these act in the event of a crash very high loads, the undesirably large seat displacements to lead can, whereby the risk of injury is increased by vehicle occupants. It is particularly problematic when a rear-end crash Motor vehicle seat strikes at high setting to the rear.
Es
sind Sitzhöhenverstellungen
bekannt, bei denen die beiden hinteren Lenker direkt angetrieben werden,
wobei dann die Antriebsorgane die hinteren Lenker in jeder eingestellten
Höhenlage
crashsicher arretieren. Das Vorsehen von Antrieben für jeden
der hinteren Lenker erhöht
jedoch die Herstellungskosten und ist aus Platzgründen häufig nicht
realisierbar. Es sind daher Kraftfahrzeugsitze bekannt, bei denen nur
einer der hinteren Lenker direkt angetrieben ist, wobei der Lenker
auf der gegenüberliegenden
Sitzseite im Crashfall durch ein trägheitssensitives Element blockiert
wird. Ein derartiger Kraftfahrzeugsitz ist in der
Die
Die oben beschriebenen, bekannten Lösungen haben den Vorteil, dass die Höhenverstellung in jeder eingestellten Höhenlage crahsicher blockiert ist, haben aber den Nachteil, dass sie relativ aufwendig sind.The described above, known solutions have the advantage that the height adjustment in every adjusted altitude crahsicher is blocked, but have the disadvantage that they are relative are expensive.
Neben
höhenverstellbaren
Kraftfahrzeugsitzen sind auch faltbare Kraftfahrzeugsitze bekannt, bei
denen Rückenlehne
und Sitzteil so miteinander gekoppelt sind, dass sich der Kraftfahrzeugsitz
beim Vorklappen der Rückenlehne

anhebt (z.B.
Aufgabe der vorliegenden Erfindung ist es, einen Kraftfahrzeugsitz gattungsgemäßer Art zur Verfügung zu stellen, bei dem im Falle eines Crashs ein übermäßiges Absacken zum Fahrzeugboden hin mit einfachen Mitteln verhindert wird.task The present invention is a motor vehicle seat of the generic type to disposal to provide, in the event of a crash excessive bagging to the vehicle floor is prevented by simple means.
Diese Aufgabe wird erfindungsgemäß mit einem Kraftfahrzeugsitz gelöst, der die Merkmale des Anspruchs 1 aufweist.These Task is according to the invention with a Motor vehicle seat solved, having the features of claim 1.
Als trägheitssensitives Element kommt erfindungsgemäß also ein einfaches Pendel zur Anwendung, welches im Heckcrashfall nach hinten bzw. im Frontcrashfall nach vorn in eine Stützposition ausschlägt, in der auf das Sitzteil wirkende Kräfte in das Chassis abgeleitet werden. Die Pendelstütze entlastet damit die Antriebsorgane der Höhenverstellung bzw. die Verriegelung. Der Vorteil des einfachen Aufbaus der trägheitssensitiven Blockierung des Sitzteils wird bei höhenverstellbaren Sitzen damit erkauft, dass die Pendelstütze nicht im gesamten Höheneinstellbereich des Sitzes ihre Wirkung entfalten kann, sondern in Abhängigkeit von ihrer Länge und dem Anbringungsort ihrer Schwenkachse als Anschlag dient, der ein weiteres Absacken des Sitzteils im Crashfall verhindert. Dabei werden die Länge der Pendelstütze und der Anbringungsort ihrer Schwenkachse sinnvoller Weise so gewählt, dass das Sitzteil aus seiner höchsten Höheneinstellung nur z.B. bis zur Hälfte des Verstellweges nach unten absacken kann, wodurch verhindert wird, dass das Sitzteil vollständig nach unten durchschlägt. Das trifft auch auf die faltbaren Sitze zu. Damit wird dem Umstand Rechnung getragen, dass im Crashfall bei sehr hoch eingestellten Sitzen die Verletzungsgefahr durch Verlagerung des Sitzes besonders groß ist.When inertia sensitive Element thus comes according to the invention simple pendulum for application, which in the rear crash case to the rear or in the front crash case forward to a support position ausschlägt in the forces acting on the seat part be derived in the chassis. The pendulum support thus relieves the drive organs the height adjustment or the lock. The advantage of the simple construction of the inertia-sensitive Blocking of the seat part becomes with height-adjustable seats with it bought that pendulum support not in the entire height adjustment range of the seat can take effect, but in dependence of their length and the mounting location of its pivot axis serves as a stop, the prevents further sagging of the seat part in the event of a crash. there become the length the pendulum support and the location of their pivot axis meaningful way chosen so that the seat part from its highest height adjustment only e.g. to the half of the adjustment can sag down, thereby preventing that the seat part is complete blows down. This also applies to the foldable seats. This will take into account the circumstance worn that in the event of a crash at very high adjusted seats Risk of injury due to relocation of the seat is particularly large.
In vorteilhafter Ausgestaltung der Erfindung ist die Pendelstütze deformierbar ausgeführt, so dass im Crashfall ein kontrollierter Energieabbau erfolgt.In Advantageous embodiment of the invention, the pendulum support is deformable executed so that in the event of a crash a controlled energy reduction takes place.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den übrigen Unteransprüchen.Further advantageous embodiments of the invention will become apparent from the other dependent claims.
