Abstract

The car seats are rigidly supported on the floor construction (8) and have a reinforced seat back (1). This is extended over the head of the seat occupant to form a streamlined headrest (3). This reaches to just under the roof of the car. The frame is strong enough to prevent the roof from caving in if the vehicle rolls over. The construction is simpler than a purpose built body frame. It can be fitted to any vehicle and does not encroach on the space inside the vehicle.

Description

Uberrollstütze zum Abstützen der Dachkonstruktion vonRoll-over support to support the roof structure of

Personenkraftwagen" Die Erfindung betrifft eine überrollstütze für Personenkraftwagen. Passenger cars "The invention relates to a roll-over support for Passenger cars.

nie Erfindung verhindert bei eventuellen Unfällen mit Überschlagen des Fahrzeuges das Eindrücken des Daches.Invention never prevents possible accidents with overturning of the vehicle pressing in the roof.

Es ist bekannt, daß zur Verhinderung des Eindrückens eines flaches hei verschiedenen Fahrzeugen verstärkte nachkonstruktionen oder nachträglich Rohrkonstruktionen eingebaut werden.It is known that to prevent the impression of a flat Reinforced replicas of various vehicles or subsequent tubular structures to be built in.

Diese bekannten Schutzvorrichtungen sind aufwendig und umständlich.These known protective devices are complex and cumbersome.

nie Erfindunq hat die Aufhabe einen überrollschutz auf billigere und nicht umständliche Art zu ermöglichen Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine entsprechende StUtzkonstruktion, z.B. Pahmenkonstruktion, in den Rückenlehnen des Vordersitzes einaehaut wird. Fine solche Stützkonstruktion in der Sitzlehne muß bis knapp unter das Wagendach, zumindestens aher höher als der Kopf des Sitzenden, reichen.Never invention has the aim of a roll-over protection on cheaper and not to enable cumbersome way This object is achieved according to the invention solved that a corresponding support structure, e.g. frame structure, in the Backrests of the front seat is covered. Fine such support structure in the The seat back must be just below the roof of the car, at least a little higher than the head of the sitter, rich.

Die Vorteile der Erfindung sind, daß aufwendige und umständliche Zusatzkonstruktionen entfallen und der Sitz eine integrierte Kopf stütze besitzt.The advantages of the invention are that complex and cumbersome additional constructions omitted and the seat has an integrated headrest.

Beim Überrollen des Fahrzeuges werden durch den stabilen Rahmen in der Rückenlehne die Belastungen direkt an den Fahrzeugrahmen weitergeleitet. Durch die günstige Lage der Rückenlehnen der Vordersitze wird ungefähr in der Wagenmitte in Längsrichtung die Belastung an vier Punkten (2 Außenwände und 2 Sitzlehnen) aufqenommen.When the vehicle rolls over, the stable frame in the backrest puts the loads directly on the vehicle frame forwarded. Due to the favorable position of the backrests of the front seats, it is approximately in the middle of the car In the longitudinal direction, the load was absorbed at four points (2 outer walls and 2 seat backs).

Ein Ausffihrunqsbeisnlel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Fig. 1 Längsschnitt durch einen PKW Fig. 2 Rückenansicht der Sitzlehne Der Überrollbügel 7 ist in der RUckenlehne 1 der Vordersitze so eingebaut, daß die Rahmenkonstruktion 7 mit der Oberkante 4 knann bis unter die Dachkonstruktion 6 reicht. Die Rahmenkonstruktion 7 ist so konstruiert, daß die Rückenlehne 1 und Kopfstütze 3 angebracht werden kann.Fig. 1 longitudinal section through a car Fig. 2 back view of the seat back The roll bar 7 is installed in the backrest 1 of the front seats so that the The frame construction 7 with the upper edge 4 can reach under the roof construction 6 enough. The frame structure 7 is constructed so that the backrest 1 and headrest 3 can be attached.
