Abstract
Description
Die Erfindung betrifft eine Sicherheitseinrichtung für Kraftfahrzeuge gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a safety device for motor vehicles according to the preamble of claim 1.
Eine
Sicherheitseinrichtung der gattungsgemäßen Art
beschreibt z. B. die
Aufgabe der Erfindung ist es, eine Sicherheitseinrichtung der gattungsgemäßen Art vorzuschlagen, die im relevanten Fußraumbereich des Kraftfahrzeuges im Crashfall erhöhte, schützende Dämpfungseigenschaften bereitstellt.task The invention is a safety device of the generic type To propose way in the relevant footwell of the motor vehicle increased in the event of a crash, protective damping properties provides.
Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung beschreiben die Unteransprüche.These Object is according to the invention with the characterizing Characteristics of claim 1 solved. Advantageous embodiments The invention describes the subclaims.
Erfindungsgemäß wird vorgeschlagen, dass die Dämpfungsplatte durch zumindest zwei Dämpfungsabschnitte gebildet ist, von denen zumindest einer durch bei einem Unfall aktivierte Mittel derart verschiebbar ist, dass im Bereich der Fußauflage des Insassen die doppelte Dicke der Dämpfungsplatte vorliegt. Somit gelingt es, im regulären Betriebszustand des Kraftfahrzeuges bei üblicher Dämpfung von Fahrgeräuschen, etc. ausreichenden Fußraum bereitzustellen und gleichzeitig in einem Crashfall eine erhöhte, schützende Dämpfung zu den unteren Extremitäten der Insassen zu schaffen.According to the invention proposed that the damping plate by at least two damping sections is formed, of which at least a means activated by an accident means so displaced is that in the footrest of the occupant double the Thickness of the damping plate is present. Thus, it succeeds in the regular operating condition of the motor vehicle in usual Damping of driving noise, etc. sufficient Provide footwell and at the same time in a crash an increased, protective cushioning too to create the lower extremities of the occupants.
Bevorzugt können beide Dämpfungsabschnitte aufeinander zu verschiebbar sein. Dies ermöglicht geringere Verschiebewege, die zu einer deutlich verkürzten Ansprechzeit der Sicherheitseinrichtung beitragen.Prefers Both damping sections can face each other be displaceable. This allows smaller displacement paths, which leads to a significantly reduced response time of the safety device contribute.
In vorteilhafter Weise können die aneinander anliegenden Trennflächen der Dämpfungsabschnitte der Dämpfungsplatte rampenförmig derart schräg ausgeführt sein, dass sie als Abweiser wirkend eine Verschiebung der Dämpfungsplatten übereinander begünstigen.In Advantageously, the adjoining interfaces the damping portions of the damping plate ramped be designed obliquely so that they serve as a deflector acting to favor a shift of the damping plates one above the other.
Ferner können die Verschiebung eines oder beider Dämpfungsabschnitte der Dämpfungsplatte mittels zumindest eines Crashsensors auslösbar sein. Derartige Crashsensoren z. B. für die Auslösung von Airbags sind in modernen Kraftfahrzeugen ohnehin vorhanden und können entsprechend ohne Mehraufwand genutzt werden.Further can be the displacement of one or both damping sections the damping plate by means of at least one crash sensor be triggered. Such crash sensors z. For example the deployment of airbags are in modern vehicles anyway available and can be used accordingly without extra effort become.
Zur Erzielung einer funktionell günstigen Konstruktion bei geringem Montageaufwand können die Dämpfungsabschnitte der Dämpfungsplatte in einem gemeinsamen Rahmen mit seitlichen Führungen verschiebbar angeordnet sein, die praktisch als Vormontageeinheit in den Fußraum des Kraftfahrzeuges montierbar ist.to Achieving a functionally favorable construction low installation costs, the damping sections the damping plate in a common frame with lateral Guides to be arranged slidably, practically as a pre-assembly unit can be mounted in the footwell of the motor vehicle.
Dabei können die Dämpfungsabschnitte bevorzugt über vorgespannte Federn betätigbar sein, deren Halterung bei einem Unfall lösbar ist. Die Halterung kann gegebenenfalls so ausgeführt sein, dass bei einem unfallbedingten Auftreten von Stößen bzw. Verzögerungen ein selbsttätiges Auslösen auftritt.there the damping sections can preferably over preloaded springs be actuated, the holder at an accident is solvable. The bracket may optionally be designed so that in an accidental occurrence from bumps or delays an automatic Triggering occurs.
Bevorzugt wird jedoch vorgeschlagen, dass die Halterung der Federn mechanisch, elektrisch oder pyrotechnisch lösbar ist. Dies stellt eine zuverlässige Funktion der Sicherheitseinrichtung auch über eine lange Betriebszeit des Kraftfahrzeuges sicher.Prefers However, it is proposed that the mounting of the springs mechanically, electrically or pyrotechnically solvable. This constitutes one Reliable function of the safety device also over a long operating time of the motor vehicle safely.
Des weiteren können in vorteilhafter Weise einer oder beide Dämpfungsabschnitte der Dämpfungsplatte bei einem Unfall mittels Gaszylinder verschiebbar sein, die pyrotechnisch gezündet und druckbeaufschlagt werden.Of others can advantageously one or both Damping sections of the damping plate at a Accident be displaced by gas cylinder, the pyrotechnic be ignited and pressurized.
Schließlich können auch die Mittel zum Verschieben der Dämpfungsabschnitte an den seitlichen Führungen des die Dämpfungsplatte einfassenden Rahmens vorgesehen sein, wodurch eine die gesamte Sicherheitseinrichtung umfassende Vormontageeinheit geschaffen wird, die nur noch schaltungstechnisch mit einem Crashsensor zu verbinden ist.After all can also be the means for moving the damping sections on the lateral guides of the damper plate be provided enclosing frame, whereby one the entire safety device comprehensive pre-assembly unit is created, which only circuit technology to connect with a crash sensor.
Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand der grob schematischen Zeichnung näher erläutert.One Embodiment of the invention is described below of the roughly schematic drawing explained in more detail.
