Die Erfindung betrifft eine Struktur für einen Fahrzeugsitz, welcher mit einer schrägen Stützfläche zum Vermeiden des Durchtauchens des Sitzinsassen im Falle einer Unfalls (Anti-Submarining) ausgestattet ist.The invention relates to a structure for a vehicle seat, which is equipped with an inclined support surface for avoiding the immersion of the seat occupant in the event of an accident (anti-submarining).
Fahrzeugsitze mit einer Schaumstruktur bzw. einem energieabsorbierenden Strukturelement bzw. einer Anti-Durchrutscheinrichtung sind allgemein bekannt, insbesondere aus den Druckschriften DE 198 56 162 A1 , DE 198 44 307 A1 , DE 195 41 999 C2 und DE 10 2004 035 598 A1. Hierbei ist nachteilig, dass keine gewichtsmäßig optimierte Lösung für ein Strukturelement eines Sitzteils eines Fahrzeugsitzes bereitgestellt wird.Vehicle seats with a foam structure or an energy-absorbing structural element or an anti-slip device are generally known, in particular from the publications DE 198 56 162 A1, DE 198 44 307 A1, DE 195 41 999 C2 and DE 10 2004 035 598 A1. A disadvantage here is that no weight-optimized solution for a structural element of a seat part of a vehicle seat is provided.
Aufgabe der vorliegenden Erfindung ist es, einen Fahrzeugsitz mit einem Sitzteil und einer Stützfläche zur Vermeidung oder zur Verminderung eines Antisubmarining-Effekts (Durchrutschen eines Teils des auf dem Fahrzeugsitz befindlichen Sitzinsassen unter einen Beckengurt bei einem Vorwärtsunfalls) zu schaffen, wobei zum einen die erforderliche Stabilität des Sitzteil erreicht wird, zum anderen aber auch eine gewichtsmäßig optimierte sowie montagetechnisch einfache Ausbildung realisiert wird.Object of the present invention is to provide a vehicle seat with a seat part and a support surface to avoid or reduce an anti-submarining effect (slipping a portion of the seat occupant seated on the vehicle seat under a lap belt in a forward crash), on the one hand, the required stability the seat part is achieved, but on the other hand, a weight optimized and easy mounting technology is realized.
Die Aufgabe wird gelöst durch einen Fahrzeugsitz mit einem Sitzteil, wobei das Sitzteil eine Stützfläche zur Vermeidung oder zur Verminderung eines Antisubmarining-Effekts (Durchrutschen eines Teils des auf dem Fahrzeugsitz befindlichen Sitzinsassen unter einen Beckengurt bei einem Vorwärtsunfalls) aufweist, wobei das Sitzteil zwischen der Stützfläche und einem Wabenelement eine Schaumstruktur aufweist. Hierdurch ist es erfindungsgemäß vorteilhaft möglich, dass auf die Stützfläche im Falle eines Unfalls wirkende Kräfte (insbesondere solche Kräfte, die der Beckenknochen oder dem Beckenknochen benachbarte Knochen oder sonstige Körperteile des auf dem Fahrzeugsitz befindlichen Sitzinsassen auf die Stützfläche als Folge der bei einem Unfall in Richtung der Erstreckungsrichtung des Sitzteils ausgehend von der Rückenlehne (d.h. bei einem Vorwärtsunfalls, wenn der Sitz in Fahrtrichtung ausgerichtet ist) ausüben) trotz eines vergleichsweise dünnen Materials der Stützfläche derart in das Sitzteil weitergeleitet werden, dass es zu einem insgesamt vorteilhaften Verhalten des Sitzteils dadurch kommt, dass weder eine zu große Deformation (d.h. bei zu geringer Festigkeit der Stützfläche) mit dem Risiko eines zu großen Durchrutschens des Sitzinsassen noch eine zu geringe Deformation (d.h. bei zu großer Festigkeit der Stützfläche) mit dem Risiko zu großer Kräfte auf Teile des Sitzinsassen, insbesondere Teile des Beckenknochens, erfolgt.The object is achieved by a vehicle seat having a seat part, the seat part having a support surface for avoiding or reducing an anti-submarining effect (slippage of a part of the seat occupant located on the vehicle seat under a lap belt in a forward crash), wherein the seat part between the support surface and a honeycomb member having a foam structure. As a result, it is advantageously possible according to the invention for forces acting on the support surface in the event of an accident (in particular those forces which are adjacent to the pelvic bone or the pelvic bone or other body parts of the seat occupant located on the vehicle seat on the support surface as a result of an accident in the direction of the extension direction of the seat part starting from the backrest (ie in a forward accident, when the seat is aligned in the direction of travel exercise) despite a comparatively thin material of the support surface are forwarded in the seat part that it an overall advantageous behavior of the seat part comes from the fact that neither too great a deformation (ie too low strength of the support surface) with the risk of too much slipping of the seat occupant still too little deformation (ie too great strength of the support surface) with the risk To large forces on parts of the seat occupant, especially parts of the pelvic bone occurs.
Erfindungsgemäß ist es insbesondere bevorzugt, dass die Stützfläche als Sitzkissenträger ausgebildet ist und insbesondere eine wannenförmige oder flächig erstreckte Formgebung aufweist. Hierdurch ist es erfindungsgemäß vorteilhaft möglich, dass sich oberhalb des Sitzkissenträgers in herkömmlicher Weise eine Polsterung des Sitzteils befindet, die einen großen Komfort für den Sitzinsassen für den Normalgebrauch des Fahrzeugsitzes bietet.According to the invention, it is particularly preferred that the support surface is designed as a seat cushion carrier and in particular has a trough-shaped or areally extended shape. As a result, it is advantageously possible according to the invention for there to be a padding of the seat part in a conventional manner above the seat cushion support, which provides great comfort for the seat occupant for normal use of the vehicle seat.
Weiterhin ist erfindungsgemäß bevorzugt, dass die Stützfläche als eine metallene Stützfläche und/oder als eine ein Kunststoffmaterial aufweisende Stützfläche vorgesehen ist. Hierdurch kann die Stützfläche besonders kostengünstig und gewichtsmäßig leicht ausgebildet werden, so dass insgesamt der Fahrzeugsitz ein geringes Gewicht aufweist und damit potentiell auch mit geringeren Kosten herstellbar ist.Furthermore, it is preferred according to the invention that the support surface is provided as a metal support surface and / or as a support surface having a plastic material. In this way, the support surface can be made particularly cost-effective and lightweight, so that overall the vehicle seat has a low weight and thus potentially can be produced at a lower cost.
Ferner ist es erfindungsgemäß bevorzugt vorgesehen, dass die Stützfläche zu einer Vorderkante des Sitzteils hin ansteigend vorgesehen ist. Eine solche Anordnung der Stützfläche erlaubt es in vorteilhafter Weise eine gute Antisubmarining-Wirkung zu erzielen, dass die Gefahr des Durchrutschens eines Sitzinsassen unter den Beckengurt zu verringern.Furthermore, it is preferably provided according to the invention that the support surface is provided ascending to a front edge of the seat part. Such an arrangement of the support surface advantageously makes it possible to achieve a good anti-submarine effect, which reduces the risk of a seat occupant slipping under the lap belt.
Erfindungsgemäß ist weiterhin auch bevorzugt, dass die Stützfläche als dünnwandige und im Falle eines Unfalls zur Deformation vorgesehene Stützfläche vorgesehen ist. Durch die Formgebung und Materialstärke der Stützfläche ist es damit erfindungsgemäß vorteilhaft möglich, eine große Variabilität hinsichtlich des Deformationsverhaltens zu erzielen.According to the invention, it is also preferable for the support surface to be provided as a thin-walled support surface intended for deformation in the event of an accident. Due to the shape and material thickness of the support surface, it is thus possible according to the invention advantageously to achieve a large variability with respect to the deformation behavior.
Weiterhin ist es erfindungsgemäß auch bevorzugt vorgesehen, dass unterhalb der Stützfläche die Schaumstruktur und das Wabenelement angeordnet ist, wobei die Schaumstruktur insbesondere das Wabenelement stoffschlüssig mit der Stützfläche verbindend vorgesehen ist.
