Abstract
Description
Die Erfindung betrifft eine Sicherheitsgurtvorrichtung, aufweisend ein zumindest teilweise aufblasbares, mindestens zwei Gurtbandlagen aufweisendes Gurtband.The invention relates to a safety belt device, comprising an at least partially inflatable, at least two Gurtbandlagen exhibiting webbing.
Aus
Nachteilig hierbei ist die Tatsache, dass beim Aufblasvorgang im Bereich des Beckens eine Gurtlose entsteht, so dass sich im Falle eines Unfalls die Vorverlagerung des Insassen im Becken vergrößert und dies zu einer schlechteren Ankopplung an das gesamte System führt.The disadvantage here is the fact that during the inflating process in the area of the pelvis belt slack arises, so that increases in the event of an accident, the forward displacement of the occupant in the pool and this leads to a poorer coupling to the entire system.
Aufgabe der vorliegenden Erfindung ist es daher, eine Sicherheitsgurtvorrichtung mit aufblasbarem Gurtband bereitzustellen, die insbesondere im Beckenbereich, also im Beckengurtbandbereich, eine möglichst geringe Gurtlose beim Einsatz erzeugt, um eine möglichst gute Anbindung des Fahrzeuginsassen zu gewährleisten.The object of the present invention is therefore to provide a safety belt device with an inflatable belt, which, in particular in the pelvic area, ie in the lap belt area, generates the smallest possible belt slack during use in order to ensure the best possible connection of the vehicle occupant.
Dieses Problem wird gelöst durch eine erfindungsgemäße Sicherheitsgurtvorrichtung nach Anspruch 1.This problem is solved by a safety belt device according to the invention according to
Die erfindungsgemäße Sicherheitsgurtvorrichtung weist auf ein zumindest teilweise aufblasbares, mindestens zwei Gurtbandlagen aufweisendes Gurtband, wobei das Gurtband gurtaufrollerstraffbar – also straffbar ist mittels eines Gurtaufrollers – ist bzw. im Einsatz gurtaufrollergestrafft wird.The seatbelt device according to the invention has an at least partially inflatable, at least two Gurtbandlagen exhibiting webbing, the webbing gurtaufollerpermeable - so is tightened by means of a belt retractor - is or gurtaufrollergestrafft in use.
Einer der Kerngedanken der vorliegenden Erfindung ist es, die im Vergleich zum Stand der Technik relativ große Gurtlose zu minimieren, indem das aufblasbare bzw. aufgeblasene Gurtband im Einsatz gestrafft wird über den Gurtaufroller.One of the principles of the present invention is to minimize belt slack relative to the prior art by tightening the inflated webbing in use over the belt retractor.
Beispielsweise und insbesondere, da sich dies in der Praxis als besonders vorteilhaft herausgestellt hat, ist es, mittels einer einzigen Aktuationseinheit, beispielsweise und insbesondere einer Gasgeneratoreinheit, beispielsweise und insbesondere einer pyrotechnischen Gasgeneratoreinheit, sowohl das Gurtband im Einsatz zu straffen bzw. dass das Gurtband straffbar ist als auch das Gurtband zumindest teilweise aufblasbar ist bzw. im Einsatz zumindest teilweise aufgeblasen wird.For example, and in particular, since this has proved to be particularly advantageous in practice, it is by means of a single Aktuationseinheit, for example, and in particular a gas generator unit, for example, and in particular a pyrotechnic gas generator unit, both to tighten the webbing in use or that the webbing tightened is as well as the webbing is at least partially inflatable or is at least partially inflated in use.
In diesem Kontext ist es vorteilhaft, wenn zwischen den beiden Gurtbandlagen eine Schlauchlanze angeordnet ist, insbesondere, wenn die Schlauchlanze ein Schutzgewebe aufweist, um ein zuverlässiges und sicheres Aufblasen im Einsatzfall sicherzustellen und eine Verletzung des Fahrzeuginsassen durch die pyrotechnisch erzeugten Gase möglichst zu vermeiden.In this context, it is advantageous if between the two Gurtbandlagen a hose lance is arranged, in particular, if the hose lance has a protective fabric to ensure reliable and safe inflation during use and avoid injury to the vehicle occupant as possible by the pyrotechnic gases.
Besonders vorteilhaft ist es, wenn die Gurtbandlagen gemeinsam an einer Strafferwelle des Gurtaufrollers angebracht sind, um eine besonders einfache und dennoch zuverlässige Ausführungsform bereitzustellen.It when the Gurtbandlagen are mounted together on a tightening shaft of the belt retractor to provide a particularly simple, yet reliable embodiment is particularly advantageous.
Weiterhin ist es von Vorteil, wenn die erfindungsgemäße Sicherheitsgurtvorrichtung derart eingestellt ist, dass vor dem Einsetzen der Gurtaufrollerstraffung des Gurtbandes das Gurtband im Bereich zwischen Schloßzunge und Gurtaufroller bereits zumindest nahezu vollständig bis vollständig aufgeblasen ist – dies wird in der Regel durch entsprechend angeordnete Sensoren und eine elektronische Auswerteeinheit nebst eventuell weiterer elektronischer oder elektromechanischer Module realisiert –, um auf diese Weise praktisch keine Gurtlose im Beckenbereich des Fahrzeuginsassen im Falle eines Einsatzes zu haben.Furthermore, it is advantageous if the safety belt device according to the invention is set such that prior to insertion of the belt retractor of the webbing, the webbing in the area between the latch plate and belt retractor is already at least almost completely completely inflated - this is usually by appropriately arranged sensors and a realized electronic evaluation together with possibly further electronic or electromechanical modules - to have virtually no slack in the pelvic region of the vehicle occupant in the event of use in this way.
Weiterhin ist es von Vorteil, wenn das Gurtband endbeschlagstraffbar – also straffbar ist über einen Endbeschlag, also über einen Beschlag, an dem das Gurtband endseitig fixiert ist –, ist bzw. im Einsatz endbeschlaggestrafft wird und/oder das Gurtband schloßzungenstraffbar – also straffbar ist über die Schloßzunge bzw. über das im Einsatz mit der Schloßzunge verbundene Gurtschloß – ist bzw. im Einsatz schloßzungengestrafft wird, um neben der Gurtaufrollstraffung eine noch intensivere Straffung des Gurtbandes bereitzustellen.Furthermore, it is advantageous if the strap is endbeschlagstraffbar - so tightened via a fitting, so a fitting to which the strap is fixed end, is - or in use endbeschlagfft and / or the strap lockable tongue - so tightened is about the buckle or on the connected in use with the buckle buckle - is or in use latches strained to provide an even more intense tightening of the webbing next to the Gurtaufrollstraffung.
Schließlich ist es von Vorteil, wenn mittels der Aktuationseinheit das Gurtband endbeschlagstraffbar ist bzw. im Einsatz endbeschlaggestrafft wird, um auf diese Art und Weise mit Hilfe lediglich der einzigen Aktuationseinheit sowohl eine Gurtaufrollerstraffung als auch eine Endbeschlagstraffung zu realisieren, was zu einer sehr effektiven Straffung des Gurtbandes und somit einer hohen Sicherheit führt bei einer relativ einfachen und kostengünstigen Ausführungsform, beispielsweise und insbesondere mittels einer pyrotechnischen Gasgeneratoreinheit.Finally, it is advantageous if by means of the actuation unit, the webbing is endbeschlagffbar or end fittings tightened in use to realize in this way with the help of only the single Aktuationseinheit both a belt retractor and a Endbeschlagstraffung, resulting in a very effective streamlining the Gurtbandes and thus a high security leads in a relatively simple and inexpensive embodiment, for example, and in particular by means of a pyrotechnic gas generator unit.
