"Sitz für Kraftwagen""Seat for motor vehicles"
Bei Unfällen, insbesondere beim Frontalaufprall eines Fahrzeuges, kann es vorkommen, daß angegurtete Fahrzeuginsassen aufgrund der Nachgiebigkeit des Sitzkissens nach unten in das Sitzkissen hineingedrückt werden, wobei der Beckengurt am Unterleib hochrutscht und sich unter die Rippen schiebt. Verletzungen von inneren Organen, hohe Kopfverzögerungen bzw. unzulässige HIC-VTerte des Kopfes sowie teilweise Kopfverletzungen durch Aufprall auf Fahrzeugteile können die Folge sein.In the event of accidents, especially in the event of a frontal collision with a vehicle, it can happen that vehicle occupants are belted due to the flexibility of the seat cushion are pressed down into the seat cushion, the lap belt slides up the abdomen and slides under the ribs. Injuries to internal organs, high head lags or inadmissible HIC-V values of the head as well as partially Head injuries from impact with vehicle parts can result.
Bekannt sind Fahrzeugsitze, bei denen ein Schaumstoffpolster in einen schalenförmigen Rahmen eingelegt ist. Durch eine relativ geringe Dicke des Polsters auf einer nach vorn hin ansteigenden Schale im vorderen Bereich soll erreicht werden, daß der Insasse beim Frontalaufprall nach kurzem Federweg von der Schale abgefangen wird und somit das Gesäß des Insassen über den normalen Federweg hinaus nicht weiter in das Sitzkissen eintauchen und einfedern kann. Diese Gestaltung geht jedoch erheblich zu Lasten des Sitzkomforts. Sie hat ein relativ hartes Aufsitzen und damit eine erhebliche Komforteinbuße zur Folge.Vehicle seats are known in which a foam padding is inserted into a bowl-shaped frame. Due to a relatively small thickness of the pad on a forward rising shell in the front area should be achieved that the occupant in a frontal collision after a short spring deflection is caught by the shell and thus the buttocks of the occupant cannot continue beyond the normal spring travel can dip into the seat cushion and deflect. However, this design is significantly at the expense of seating comfort. It results in a relatively hard sitting and thus a considerable loss of comfort.
Der Erfindung lag die Aufgabe zugrunde, einen Fahrzeugsitz zu schaffen, der ohie jeglichen Verlust an Sitzkomfort mitThe invention was based on the object of creating a vehicle seat that would have any loss of seating comfort

einfachen und billigen Mitteln wirksam verhindert, daß bei Unfällen, insbesondere Frontalaufprall, das Gesäß des Fahrzeuginaassen über den normalen Federweg des Sitzkissens hinaus in letzteres einfedern kann.simple and cheap means effectively prevents that at Accidents, especially head-on collisions, hit the buttocks of the vehicle can deflect into the latter beyond the normal travel of the seat cushion.
Diese Aufgabe wird erfindungsgemäß gelöst durch die im kennzeichnenden Teil des Anspruches 1 enthaltenen Merkmale.This object is achieved according to the invention by the im characterizing part of claim 1 contained features.
Möglichkeiten zur Herbeiführung der Volumenänderung des Luftkissens sind in den Ansprüchen 2 bis 4 beschrieben.Possibilities for bringing about the change in volume of the air cushion are described in claims 2 to 4.
Das im Anspruch 5 enthaltene Merkmal ermöglicht eine optimale Beaufschlagung des Luftkissens durch den Benutzer des Sitzes.The feature contained in claim 5 enables an optimal Acting on the air cushion by the user of the Seat.
Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. In der Zeichnung zeigenThe subject matter of the invention is to be described in more detail below with the aid of an exemplary embodiment shown in the drawing explained. Show in the drawing
Fig. 1 schematisch einen Längsschnitt durch einen erfindungsgemäß ausgestatteten Fahrzeugsitz, und1 schematically shows a longitudinal section through a vehicle seat equipped according to the invention, and
Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1.FIG. 2 shows a section along the line II-II in FIG. 1.
Das in der Zeichnung dargestellte Sitzkissen 1 eines Fahrzeugsitzes weist ein Polsterformteil 2 auf, das über Federn 3 gegenüber dem Sitzkissenrahmen k abgefedert ist. Unterhalb de· PoTsterformteils 2 ist ein blasebalgähnliches Luftkissen 5 angeordnet, das sich unten am Sitzkissenrahmen k abstützt.The seat cushion 1 of a vehicle seat shown in the drawing has a molded upholstery part 2 which is cushioned by means of springs 3 with respect to the seat cushion frame k. A bellows-like air cushion 5 is arranged below the molded cushion part 2 and is supported at the bottom on the seat cushion frame k.
Dieses Luftkissen 5 weist Mittel für eine Veränderung seines Volumens auf, die so ausgelegt bzw. bemessen sind, daß dasThis air cushion 5 has means for changing his Volume that is designed or dimensioned so that the

Luftkissen normale Federungsbewegungen des Sitzes durch Änderungen seines Volumens mitmacht, ohne dabei den Sitzkomfort zu beeinträchtigen, während es bei plötzlicher, kurzzeitiger dynamischer Belastung sein Volumen beibehält und so den Sitz verhärtet.Air cushion takes part in normal suspension movements of the seat by changing its volume, without impairing the comfort of the seat, while it maintains its volume in the event of sudden, short-term dynamic loads so the seat hardens.
Hierzu können entweder definierte Abströmöffnungen 6 vorgesehen sein, die auch als Ventil 7 ausgebildet sein können. Die Volumenänderung kann aber auch ermöglicht werden durch poröse Wandungsteile 8 des Luftkissens 5·For this purpose, either defined outflow openings 6 can be provided, which can also be designed as a valve 7. The change in volume can also be made possible by porous wall parts 8 of the air cushion 5
Eine optimale Beaufschlagung des Luftkissens 5 wird dadurch erreicht, daß dieses auf seiner Oberseite und/oder seiner Unterseite durch eine starre Platte 9 abgedeckt ist.An optimal application of the air cushion 5 is thereby achieves that this is covered by a rigid plate 9 on its upper side and / or its lower side.
