Abstract

The seat has a cushion (1), a backrest (3), and if necessary a headrest (5), and is fitted to the interior of aircraft or motor vehicles, in order to hold passengers who are restrained by safety belts. It has a unit which is fitted to the front section of the cushion, and which stores energy when in its initial position. The unit can release energy (9) over the full width of the hump (11) in this section, in order to adjust the shape of the cushion. The unit may be an airbag module, or may have one or more spring elements.

Description

Die Erfindung betrifft einen Sicherheitssitz bestehend aus Sitzkissen, Rückenlehne und ggf. Kopfstütze, vorzugsweise für den Innenraum von Kraftfahrzeugen und Flugzeugen, für einen Fahr-/Fluggast mit angelegtem Sicherheitsgurt.The invention relates to a safety seat consisting of Seat cushion, backrest and possibly headrest, preferably for the interior of automobiles and airplanes, for one Passenger / passenger wearing a seat belt.

Auswertungen von Unfallsimulationen mittels dynamisch arbeitender Versuchsanordnungen, wie Schlitten- oder Crash-Anlagen, zeigen, daß sich ungeschützte Fahrgäste am häufigsten durch Aufprall auf die Lenkanlage und die Armaturentafel verletzen. Eine Analyse der Straßenverkehrsunfälle bestätigt dies. Erst durch die Einführung des Sicherheitsgurts, insbesondere des Dreipunkt-Sicherheitsgurts, eine Kombination von Hüft- und Schrägschultergurt, mit dem der Fahrgast mit dem Fahrzeug verbunden ist sowie der Verbesserung in Form des Automatik-Sicherheitsgurts und des Einsatzes von Gurtstrammern haben zu einer 50 bis 60%-igen Verringerung des Verletzungsgrades beim Aufprall des Fahrgasts, insbesondere auf die Windschutzscheibe und Armaturentafel geführt. Der Aufprall, insbesondere des Kopfs und des Brustkorbs auf die Lenkanlage, hervorgerufen durch die rotatorische Vorwärtsbewegung des Oberkörpers des Fahrgasts infolge der starken Fahrzeugverzögerung, kann jedoch von einem Sicherheitsgurt nur unzureichend verhindert werden. Um solche Unfälle zu vermeiden, sind Airbag-Module entwickelt worden, die im wesentlichen aus einem Gasgenerator, einem Generatorträger und einem eingefalteten Gassack aufgebaut und vorzugsweise im Lenkrad und beifahrerseitig in der Armaturentafel eingefügt sind. Beim Aufprall eines Fahrzeugs auf ein massives Hindernis wird der Gasgenerator gezündet und durch das sich bildende Gas der Gassack entfaltet, aufgeblasen und füllt den Zwischenraum zwischen dem Lenkrad bzw. der Armaturentafel und dem Oberkörper des Fahrgasts aus. Evaluation of accident simulations using dynamic working experimental arrangements, such as sled or Crash systems show that unprotected passengers on the most often by impact on the steering system and the Injury the dashboard. An analysis of the Road traffic accidents confirm this. Only through that Introduction of the seat belt, especially the Three-point seat belts, a combination of hip and Oblique shoulder strap with which the passenger with the vehicle is connected as well as the improvement in the form of Automatic seat belts and the use of belt tensioners have a 50 to 60% reduction in Degree of injury in the event of a passenger impact, in particular led to the windshield and dashboard. Of the Impact, especially of the head and chest on the Steering system caused by the rotary Forward movement of the upper body of the passenger as a result of strong vehicle deceleration, but can be caused by one Seat belts can only be prevented inadequately. To such To avoid accidents, airbag modules have been developed which essentially consists of a gas generator, a Generator carrier and a folded gas bag built and preferably in the steering wheel and in the passenger side Dashboard are inserted. When a vehicle collides the gas generator is ignited on a massive obstacle and unfolded by the gas forming, inflated and fills the space between the steering wheel or the Dashboard and the upper body of the passenger.  

Durch diese Maßnahmen läßt sich das Risiko schwerer Unfallverletzungen deutlich reduzieren und damit die passive Sicherheit entscheidend erhöhen. Dennoch sind fallweise Verletzungen der unteren Extremitäten, insbesondere der Knie des Fahrgasts, wegen des relativ geringen Abstands der Oberschenkel zur Armaturentafel zu beobachten. Bei einem Aufprall des Fahrzeugs auf ein massives Hindernis beginnt nach der ersten Berührung der Fahrgast aufgrund seiner Massenträgheit nach vorn zu rutschen. Wenn in diesem Falle der Dreipunkt-Sicherheitsgurt den Fahrgast nicht fest am Sitz hält, werden die unteren Extremitäten und das Becken des Fahrgasts soweit nach vorn verlagert, daß insbesondere die Knie gegen den unteren Abschnitt der Armaturentafel schlagen.These measures make the risk more difficult Significantly reduce accidental injuries and thus the passive Increase security significantly. Still are case by case Injuries to the lower extremities, especially the knees of the passenger, because of the relatively small distance between the Watching thighs to the dashboard. At a Impact of the vehicle against a massive obstacle begins after the first touch of the passenger due to its Mass inertia to slide forward. If in this case the Three-point seat belt does not hold the passenger firmly on the seat holds the lower extremities and pelvis Passengers shifted so far forward that in particular the Hit the knee against the lower section of the dashboard.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, die Verlagerung der unteren Extremitäten und des Beckens des Fahr-/Fluggasts auf ein solches Maß zu reduzieren, daß im Falle eines Aufpralls des Fahrzeugs auf ein massives Hindernis das Verletzungsrisiko für die untere Extremitäten auf ein Minimum reduziert ist.It is therefore the object of the present invention that Relocation of the lower extremities and pelvis To reduce passengers / passengers to such a degree that in In the event of a vehicle colliding with a massive obstacle the risk of injury to the lower extremities Minimum is reduced.

Gelöst ist diese Aufgabe durch die im Patentanspruch 1 angegebenen Merkmale.This problem is solved by the in claim 1 specified characteristics.

In den Ansprüchen 2 und 3 sind vorzugsweise Ausführungsformen der Erfindung gemäß Patentanspruch 1 beschrieben.In claims 2 and 3 are preferred embodiments described the invention according to claim 1.

Der über die Breite des vorderen Abschnitts der Sitzfläche des Sitzkissens verlaufende Höcker verhindert eine Verlagerung der unteren Extremitäten und des Beckens des Fahrgastes in Richtung zur Armaturentafel hin. Das Gesäß wird weich und ohne Rückprallkräfte abgefangen und die Füße durch Hochdrücken der Oberschenkel aus dem Fußraum zurückgezogen, so daß diese dort nicht eingeklemmt werden können. Das Eintauchen des Oberkörpers der Fahrgasts in den entfalteten Gassack eines ggf. im Lenkrad oder auf der Beifahrerseite angebrachten Airbag-Moduls verläuft ebenfalls günstiger. Der erfindungsgemäß ausgebildete Sicherheitssitz ist auch für die Anordnung in der Hintersitzanlage eines Kraftfahrzeugs geeignet.The across the width of the front portion of the seat of the Seat cushions running humps prevent a shifting of the lower extremities and pelvis of the passenger in Direction to the dashboard. The buttocks become soft and without Rebound forces are absorbed and the feet by pushing the  Thighs withdrawn from the footwell so that these there cannot be pinched. The immersion of the Upper body of the passengers in the unfolded airbag one if necessary, in the steering wheel or on the passenger side Airbag module is also cheaper. Of the Safety seat designed according to the invention is also for the Arrangement in the rear seat system of a motor vehicle suitable.

Der eingefaltete Gassacks des Airbag-Moduls kann zwischen dem Formpolster und der Auflage des Sitzkissens, zwischen der Auflage und dem Bezug des Sitzkissens, in der Auflage oder im Formpolster angeordnet sein.The folded airbag of the airbag module can be between the Form cushion and the support of the seat cushion, between the Pad and the cover of the seat cushion, in the pad or in Shaped cushion can be arranged.

In the event of a possible impact of the motor vehicle on a massive obstacle, sensors housed in the vehicle respond, which, for. B. an ignition current on the igniter of the gas generator, which in turn ignites the squib and thus the propellant for inflating the gas bag ( 9 ) of the airbag module ( 7 ). When using a spring element assembly ( 8 ), this is triggered. After a period of time in the millisecond range, the gas bag ( 9 ) of the airbag module ( 7 ) is fully inflated or the spring elements ( 10 ) of the spring element assembly ( 8 ) are completely relieved, so that over the entire width of the front section of the seat cushion a hump ( 11 , 12 ) of the safety vehicle seat.
