Abstract

Safety and blocking rod linkages (11,12) at front and rear of vehicle once released are sprung out mechanically, pneumatically or hydraulically relative the mass center of the vehicle. The linkages (11,12) can be extended simultaneously or in sequence in response to braking or speed-responsive proximity sensors reacting to source of danger. The linkages can also be extended simultaneously at a delayed rate determined by the relaxing of the mechanical linkage springs.

Description

Die bisher bekannten und in der Praxis angewendeten Sicher­ heitseinrichtungen gegen die Folgen von Auffahrunfällen oder Frontalkarambolagen haben zwar die Unfallschwere für Fahr­ zeuginsassen im Ausmaß reduziert. Die technische Fortentwicklung hinsichtlich der allgemeinen Fahrgeschwindigkeit, der Reduzierung des Fahrzeuggewichts u. a. haben jedoch gleichzei­ tig die Wirkungsweise der heute üblichen Sicherheitselemente relativiert. An bekannten Sicherheitselementen werden hierzu Gurte und Airbags genannt, weiterhin werden konstruktionsseitig Knautschzonen im Fahrzeug vorgesehen. Alle diese Einrich­ tungen sind auf die Insassensicherung ausgerichtet, das Fahr­ zeug dagegen wird als Unfallfolge teildemoliert oder weitge­ hend zerstört.The previously known and used in practice safety devices against the consequences of rear-end collisions or Frontal carambol have the accident severity for driving witness occupants reduced in extent. The technical development in terms of general driving speed, the Reduction of vehicle weight and a. but have at the same time the mode of operation of the security elements common today relativized. Known security elements are used for this purpose Belts and airbags are also called construction Crumple zones provided in the vehicle. All of these furnishings are geared towards occupant safety, driving On the other hand, witness is partially demolished or widespread as an accident destroyed.

Ziel der vorliegenden Neuerung ist es, die immer noch unzu­ reichende Insassensicherung zu verbessern sowie das Fahrzeug gegen die gröbsten Zerstörungen bei Karambolagen zu schützen.The aim of the present innovation is that it is still too sufficient occupant protection to improve as well as the vehicle to protect against the coarsest damage to billiards.

Die Einrichtung, die bei Front- und Heckkarambolagen die Prallenergie voll oder zu großen Teilen elastisch aufnimmt und damit schwere Schäden an Insassen und Fahrzeug verhindert, ist in Fig. 1 dargestellt. Sie besteht als Beispiel aus zwei parallel in Fahrtrichtung angeordneten Hydraulikzylindern (1) die mit je zwei entgegengesetzt wirkenden Kolben (2) und geführ­ ten Kolbenstangen (3) ausgestattet sind. Mittig ist als Elas­ tizitätselement eine starke Druckfeder (4) eingefügt, die unter Vorspannung steht. Die Sperren (5) und (6) verhindern eine un­ gesteuerte Kolbenbewegung. Weiterhin ist der Zylindermantel zwischen den Kolbensperren mit einer Rohrleitung (7) versehen, die über ein Steuerventil (8) mit einer Druckkammer (9) ver­ bunden ist, die durch eine Ladepumpe (10) mit Druckluft gefüllt werden kann. In Fig. 1 sind Rohrleitung, Steuerven­ til, Druckkammer und Ladepumpe aus Gründen der übersicht­ lichen Darstellung in die Bildebene geklappt.The device which absorbs the impact energy fully or to a large extent elastically in front and rear billiards and thus prevents serious damage to occupants and vehicle is shown in FIG. 1. It consists as an example of two hydraulic cylinders ( 1 ) arranged parallel to the direction of travel, each with two oppositely acting pistons ( 2 ) and guided piston rods ( 3 ). A strong compression spring ( 4 ) is inserted in the middle as an elasticity element and is under tension. The locks ( 5 ) and ( 6 ) prevent uncontrolled piston movement. Furthermore, the cylinder jacket between the piston locks is provided with a pipeline ( 7 ) which is connected via a control valve ( 8 ) to a pressure chamber ( 9 ), which can be filled with compressed air by means of a charge pump ( 10 ). In Fig. 1 pipeline, Steuererven valve, pressure chamber and charge pump are folded for the sake of clarity union representation in the image plane.

Das Konzept der durch die Erfindung gewährleisteten Gefahrenminderung ist wie folgt beschrieben:
Bei Gefahrerkennung durch den KFZ-Führer wird er durch Teil- oder Vollbremsung auf die Situation reagieren. Durch die Bremsung wird ein Funktionsablauf eingeleitet, der sich so darstellt:
The concept of risk reduction guaranteed by the invention is described as follows:
If the driver detects danger, he will respond to the situation by braking partially or fully. Braking initiates a functional sequence that is represented as follows:

  • a) Bei Vollbremsung: Öffnung der Sperre (5), Entspannung der Druckfeder und Ausfahren des Gestänges (11) mit Kolben und Kolbenstange nach vorn in Fahrtrichtung.a) With full braking: opening the lock ( 5 ), relieving the pressure spring and extending the linkage ( 11 ) with the piston and piston rod to the front in the direction of travel.
  • b) Nachströmen der Druckluft in den Zylinder und Ausfahren des Kolbens auf Endstellung.b) Afterflow of compressed air into the cylinder and extension of the piston to the end position.
  • c) Nach Frontalaufprall wird Gestänge(11) elastisch zurück­ gedrückt, bis Sperre (5) wieder einklinkt. Dadurch wird Sperre (6) gelöst und fährt Gestänge (12) unter gleichen Bedingungen nach hinten aus.c) After a frontal impact, the linkage ( 11 ) is pressed back elastically until the lock ( 5 ) engages again. This releases the lock ( 6 ) and extends the linkage ( 12 ) to the rear under the same conditions.
  • d) Erfolgt nach Vollbremsung kein Aufprall nach Geschwindig­ keitsrückgang, wird das Ausfahren des Kolbengestänges nach hinten unabhängig ausgelöst.d) If there is no impact at high speed after full braking decrease, the extension of the piston rod triggered independently to the rear.
  • e) Unabhängig vom Reaktionsvermögen des Fahrers erfolgt das Ausfahren der Gestänge, wenn sensorisch eine rasche Annäherung des Fahrzeuges an eine Gefahrenquelle gemessen wird.e) Independent of the driver's ability to react the extension of the linkage when sensory a quick Approach of the vehicle measured to a source of danger becomes.

Im Parkbetrieb (ruhender Verkehr) wird eine verminderte Ausfahrrate front und heckseitig vorgenommen, die wesent­ lich durch die entspannte Länge der Druckfeder bestimmt wird. Dadurch wird sicher gestellt, dass Fahrzeugberüh­ rungen vom ausgerüsteten Fahrzeug aus gesehen nur an den dafür vorgesehenen Gestängeteilen erfolgen.In park operation (stationary traffic), one is reduced Extension rate made front and rear, the essential Lich determined by the relaxed length of the compression spring becomes. This ensures that vehicle contact from the equipped vehicle only on the provided parts of the linkage.
