Abstract

The entire length of the webbing in contact with the body is provided with inflatable chambers. In case of a sudden deceleration following an impact the chambers are rapidly inflated to provide an extended contact surface between the webbing and body and at the same time also the retractor mechanism blocking device operates. The chambers are fitted with bleeder valves which allow the air trapped in the inflated chambers to escape gradually at a rate related to the body weight of the user. By this process the impact energy of the body is gradually dissipated to a residue value which then is taken up by the webbing itself.

Description

Sicherheitsgurte für KraftfahrzeugeSeat belts for automobiles

Sicherheitsgurte für Kraftfahrzeuge sind in vielen Ausführungen bekannt.Seat belts for motor vehicles are known in many designs.

Die wohl gebräuchlichste Ausführung für das nicht bei Rennen eingesetzte Kraftfahrzeug ist der automatische Dreipunkt-Sicherheitsgurt. Dieser automatische Dreipunkt-Sicherheitsgurt zeichnet sich dadurch aus, daß er dem Fahrer genügend Bewegungsfreiheit lässt (Bedienung von Schaltern, Suchen im Handschuhfach, das Suchen im Radio, bedienen der Handbremse usw.) Bei plötzlicher Spannung der Gurte wird durch eine Arretierung die Aufroll- bzw.Probably the most common version for that which is not used in races Motor vehicle is the automatic three-point seat belt. This automatic A three-point seat belt is characterized by the fact that it is sufficient for the driver Freedom of movement (operating switches, searching in the glove compartment, searching on the radio, operating the handbrake, etc.) If the belt is suddenly tensioned the roll-up resp.

Abrolivorrichtung der Sicherheitsgurte blockiert und somit der sich dahinter befindliche Körper festgehalten. Der Nachteile dieser Sicherheitsgurte ist, daß im Falle einer Kollision a) bedingt durch die geringe Gurtbreite teilweise erhebliche Verletzungen (Knochen und Rippenbrüche, Leber und Milzrisse, Verletzungen im Unterleib usw.) verursacht werden b) der Körper trotz des Sicherheitsgurtes oft noch die Möglichkeit hat, wie beispielsweise bei einem Frontalaufprall des Fahrzeuges, nach vorne in Richtung des Lenkrades zu schleudern und dadurch ein Aufprall des Körpers auf das Lenkrad, das Armaturenbrett oder sogar auf die Scheibe, ermöglicht.Abrolivorrichtung the seat belts blocked and thus the itself bodies behind it held. The disadvantages of these seat belts is that in the event of a collision a) partially due to the narrow belt width significant injuries (broken bones and ribs, liver and spleen tears, injuries in the abdomen, etc.) b) the body often despite the seat belt still has the option, for example in the event of a frontal collision with the vehicle, to fling forward in the direction of the steering wheel and thereby an impact of the Body on the steering wheel, the dashboard or even on the windshield.

Gegenstand der Erfindung ist;: ein Dreipunkt-Sicherheitsgurt mit den herkömmlichen Vorteilen, aber ohne dessen Nachteile. Diese Aufgabe wird dadurch gelöst, daß das Prinzip des herkömmlichen automatischen Dreipunkt-Sicherheitsgurtes beibehalten wird, aber die auf den Körper aufliegenden Gurte über Luftkammern verfügen, die so konstruiert sind, daß sie sich im Falle einer Kollision im Bruchteile einer Sekunde aufblasen und somit die Auflagefläche der Gurte vergrößern, gleichzeitig durch dieses Aufblasen wird die Arretierung der Gurte blockiert und der Körper in seiner gerade befindlichen Position festgehalten. Die Luftkammern enthalten auch Ablassventile durch die die Luft entweichen kann, bedingt durch das auf sie wirkende Gewicht des aufgefangenen Körpers. Dadurch wird der Schwung des Körpers stark abgebaut. Den noch verbleibenden Schwung fängt dann der Sicherheitsgurt auf.The subject of the invention is ;: a three-point seat belt with the conventional advantages, but without its disadvantages. This is what makes this job solved that the principle of the conventional automatic three-point seat belt is retained, but the belts resting on the body have air chambers, which are designed in such a way that in the event of a collision they move apart by a fraction of a Inflate for a second and thus increase the contact surface of the belts, at the same time This inflation blocks the belts from being locked in place and the body is in held in its current position. The air chambers also contain Drain valves through which the air can escape, due to what is acting on them Weight of the caught body. This greatly reduces the body's momentum. The seat belt then absorbs the remaining momentum.

Ausgelöst wird das Aufblasen der Luftkammer durch einen Sensor, der in Millisekunden auf eine unfalltypische Verzögerung reagiert.The inflation of the air chamber is triggered by a sensor, the reacts in milliseconds to a typical accident delay.
