Abstract

The padded car bumper is braced on the car body by one or more flexible tubes. The tubes are connected to an air- pump driven off the engine with the output pressure of the pump corresponding to the engine speed, or road speed. As the vehicle is driven faster the pressure increases and the tubes are inflated harder. The spacing of the bumper from the car body thus increases with speed, and increases the impact absorbing capability of the bumper.

Description

Beschreibung des PNEUMATISCHEN STOSSABSORBERS Titel: PNEUMATISCHER STOSSABSORBER Anwen Bungsgebiet: Die Erfindung betrifft eine Verbesserung der Sicherheitsmassnahmen im Strassenverkehr.Description of the PNEUMATIC SHOCK ABSORBER Title: PNEUMATIC SHOCK ABSORBER Field of application: The invention relates to an improvement in safety measures in traffic.

Zseck: Der PNEUMATISCHE STOSSABSORBER kann anstelle von herkommlichen Stosstangen an Kraftfahrzeugen verwendet werden, wodurch im Falle eines Unfalls, die Wucht vermindert und die Aufprallenergie neutralisiert wird. Mit dieser Erfindung werden die Unfallschaden an Personen und Gegenstanden sehr viel geringer sein.Purpose: The PNEUMATIC SHOCK ABSORBER can replace conventional Bumpers are used on motor vehicles, which in the event of an accident, the impact is reduced and the impact energy is neutralized. With this invention the accident damage to people and objects will be much less.

Beschreibung: Es handelt sich um zwei Typen von PNEUMATISCHEN STOSSABSORBERN.Description: There are two types of PNEUMATIC SHOCK ABSORBERS.

Typ 1 ist besonders gut ver-endbtr fur die hintere Stosstange des Fahrzeuges. Dieser Typ des PNEUMATISCHEN STOSSABSORBERS besteht aus zwei uber die besamte Breite des Fahrzeuges verlaufende Stangen, die ineinander verschiebbar sind (oder aus einem verformbarem Teill, dern Zwischenraum mit luftgefüllten Gummikörpern (z.B. £igeln) aufgefullt ist. Der hintere Teil der Stosstange ist direkt mit dem Chassis verbunden und ist starr, während der vordere Teil sich eindrucken lasst. Type 1 is particularly well finished for the rear bumper of the Vehicle. This type of PNEUMATIC SHOCK ABSORBER consists of two over the entire width of the vehicle extending rods that can be slid into each other (or from a deformable part, the gap with air-filled rubber bodies (e.g. hedgehogs) is filled up. The rear part of the bumper is directly connected to the Chassis connected and rigid, while the front part can be impressed.

i:ie Pneukörper (GUMMIKÖRPER) haben die Aufgabe, die Aufprallenergie zu neutralisieren, z.B., zur Verminderung der Wucht der Aufprallunfälle. i: he tire bodies (RUBBER BODIES) have the task of the impact energy to neutralize, e.g. to reduce the impact of impact accidents.

Typ 2 ist besonders gut çeeignet fur die vordere Stoßtange an Kraftfahrzeugen und besteht aus zwei über die gesamte Front des Fahrzeuges verlaufende Stangen, welche ineinander eingeschoben oder eingeßru@kt werden konnen. Zwischen diesen beiden Teilen entsteht ein freier Raum. der hinteie Teil dieser slJei Stangen ist wiederum am Chassis befestigt und unbeweglich. Der vordere Teil agegen ist beweglich, er ist ausfahrbar und einziehbar. Dieses geschieht folgendermassen: Zwischen diesen beiden Teilen befindet sich ein aus Gummi bestehender aufblasbarer Schlauch. Bein stehenden Fahrzeug ist der Schlauch luftleer, daher zieht er sich zusammen. Das bewirkt, dass die beiden Stosstangenteile sich in diesem Zustand durch Federn zusammenziehen und den Massen der herkömmlichen Stosstangen entsprechen. Type 2 is particularly well suited for the front bumper on motor vehicles and consists of two bars running over the entire front of the vehicle, which are inserted into each other or may be included. Between these two parts create a free space. the rear part of these slJei rods is in turn attached to the chassis and immobile. The front part, on the other hand, is movable, it is extendable and retractable. This happens as follows: Between these Both parts have an inflatable tube made of rubber. leg When the vehicle is stationary, the hose is evacuated, so it contracts. That causes the two bumper parts to contract in this state by springs and correspond to the masses of conventional bumpers.

Der grosse Vorteil zeigt sich,wenn as Fahrzeug sich in Fahrt befindet.The big advantage becomes apparent when the vehicle is in motion.

Bei der Fahrt wird die Luft vom Motor-Ventilator (od. durch eine zusatzlich eingebaute Luftpumpe) in diesen Schlauch gepumpt, wodurch sich der Schlauch aufbläst und den vorderen Teil der Stosstange nach vorne hinaus schiebt. Der Vorteil ist, dass sich der Schlauch relativ zur Geschwindigkeit des Fahrzeuges weiter aufbläst und so den vorderen Teil der Stosstange ausschiebt. Durch diese ausfahrbare Stosstange wird eine grossere Knautschzone vor dem Fahrzeug geschaffen. Dieser PNEUMKTISCHE STOSSABSORBER ist in der Lage die Aufprallenergie sehr viel weicher aufzufangen und zu neutralisieren. Durch Ventile kann der Luftdruck so reguliert werden, dass mit Zunahme der Geschwindigkeit , die Stosstange weiter ausgefahren wird und einen grosseren Dämpfungseffekt erzielt.When driving, the air from the motor fan (or by an additional built-in air pump) is pumped into this hose, causing the hose to inflate and pushes the front part of the bumper forward. The advantage is, that the hose continues to inflate relative to the speed of the vehicle and so pushes out the front part of the bumper. Through this extendable bumper a larger crumple zone is created in front of the vehicle. This PNEUMATIC TABLES SHOCK ABSORBER is able to absorb the impact energy much more gently and neutralize. Valves can be used to regulate the air pressure so that as the speed increases, the bumper is extended further and one greater damping effect achieved.

Die Wirkung dieser PNEUMATIK STOSSABSORSER Stosstange kann noch durch Mitverwendung von Hydraulik oder Federn verstärkt werden.The effect of this PNEUMATIC SHOCK ABSORBER bumper can still through Use of hydraulics or springs can be reinforced.

Diese Erfindung kommt vor allem den Fussgängern zugute, die sehr oft bei kleinen Unfällen erheblich verletzt werden.This invention is of particular benefit to pedestrians, who very often be seriously injured in minor accidents.

Durch den pneumatischen Effekt wird die Aufprallwucht in solchen Fällen erheblich gemindert.In such cases, the impact force is reduced by the pneumatic effect considerably reduced.
