Abstract

Pneumatic shock absorber for motor vehicle adapted to protect vehicle body and occupant(s) at impact speeds up to 10 km/h by elastic deformation, comprises an extruded deformable, plastics tube filled with compressed air under 0.5 - 5.0 bar, heat-sealed at both ends, and fitted with a valve doubling a relief pressure valve. Advantages include possible mass prodn. with standardised dimensions; saving of relatively costly mounting brackets; free from corrosion; re-usability after minor damage caused by elastic deformation. Can be fitted simply by glueing to smooth flat vehicle body component (which also promotes even distribution of impact energy).

Description

Titel Pneumatische SicherheitsstoßstangeTitle Pneumatic Safety Bumper

Anwendungsgebiet Die Erfindung betrifft eine pneumatische Sicherheitsstoßstange für Personen- und Lastkraftwagen.Field of application The invention relates to a pneumatic safety bumper for cars and trucks.

Zweck und Aufgabe Vereinfachung der Herstellung und Montage von Stoßstangen bei Kraftfahrzeugen, Absorption von kinetischer Energie bei Kollisionen bis ca.Purpose and task To simplify the manufacture and assembly of bumpers in motor vehicles, absorption of kinetic energy in collisions up to approx.

10 Stundenkilometer.10 km / h.

Stand der Technik Viele Autohersteller unternehmen Versuche, die Sicherheit der Kraftfahrzeuginsassen durch nachgiebig gestaltete Stoßfängerkonstruktionen aus Stahl-, Kunststoff- und Gummielementen zu erhöhen. Ebenso sollen durch relativ teure und aufwendige Konstruktionen die Kaskoversicherungsklassen durch Schadenverringerung niedrig gehalten werden.State of the Art Many automakers are making attempts to improve safety of the vehicle occupants through flexible bumper constructions To increase steel, plastic and rubber elements. Likewise, through relatively expensive ones and elaborate constructions, the comprehensive insurance classes through damage reduction be kept low.

Lösung Ein extrudiertes Kunststoffteil in der Grundform eines Schlauches wird an den Enden verschweißt und über ein Ventil, das gleichzeitig als Uberdruckventil wirkt, mit Druckluft von 0,5 bis 5 bar gefüllt.Solution An extruded plastic part in the basic shape of a hose is welded at the ends and via a valve that doubles as a pressure relief valve acts, filled with compressed air from 0.5 to 5 bar.

Erzielbare Vorteile Vereinheitlichung und damit Verbilligung von Stoßstangen bei Kraftfahrzeugen.Achievable benefits Standardization and thus cheaper bumpers in motor vehicles.

Einsparung der aufwendigen Halterungen.No need for expensive brackets.

Keine Korrosion.No corrosion.

Wiederverwendbarkeit nach Bagatellschäden infolge elastischer VerformungReusability after minor damage due to elastic deformation

Claims (1)

Oberbegriff 1. Pneumatische Sicherheitsstoßstange für Kraftfahrzeuge mit Schutz der Karosserie und der Insassen bei Aufprallgeschwindigkeiten bis ca.Generic term 1. Pneumatic safety bumper for motor vehicles with protection of the body and the occupants at impact speeds of up to approx. 10 km/h durch elastische Verformung, Kennzeichnender Teil dadurch gekennzeichnet, daß die pneumatische Sicherheitsstoßstange aus verformbarem Kunststoff mit Druckluftfüllung von 0,5 bis 5 bw.und Sicherheitsventil besteht. 10 km / h due to elastic deformation, a characteristic part as a result characterized in that the pneumatic safety bumper is made of deformable plastic with a compressed air filling of 0.5 to 5 respectively and a safety valve. Oberbegriff des Unteranspruchs 2. Pneumatische Sicherheitsstoßstange nach Anspruch 1, Kennzeichnender Teil des Unteranspruchs dadurch gekennzeichnet, daß die Kunststoffstoßstange auf einem glattflächigen Karosserieteil aufliegen kann und dadurch die Aufprallenergie gleichmäßig verteilt wird. Außerdem ist eine Montage durch minimale Befestigungspunkte sowie durch Aufkleben möglich.Preamble of dependent claim 2. Pneumatic safety bumper according to claim 1, characterizing part of the sub-claim, characterized in that that the plastic bumper can rest on a smooth-surfaced body part and thereby the impact energy is evenly distributed. In addition, there is an assembly possible through minimal attachment points as well as by gluing.
