Abstract
Description
Die Erfindung betrifft eine Rückhaltevorrichtung für einen auf einem Fahrzeugsitz plazierten Fahrzeugin sassen der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a restraint for a vehicle placed on a vehicle seat sat the specified in the preamble of claim 1 Genus.
Die Rückhaltewirkung des Sicherheitsgurtes wird während eines Frontalaufpralls durch eine günstige Insassenkinematik wesentlich verbessert. Hierzu gehört ein sehr hoch gelegenes Abstützniveau des Sitzkissens, das beim Crash nicht nachgibt und dadurch ein Durch tauchen des angegurteten Insassens nach unten nicht zuläßt. Aus Sitzkomfortgründen kann jedoch dieses Niveau nicht grundsätzlich in die unfalltechnisch höchste Position gelegt werden.The restraint effect of the seat belt is during a head-on collision by a cheap one Occupant kinematics significantly improved. Which also includes a very high support level of the seat cushion, that does not give way in a crash and therefore a through do not dive the belted occupant down allows. However, this can be done for reasons of seating comfort Level not basically in the accident technology highest position.
Bei einer bekannten Gurthaltevorrichtung der eingangs genannten Art (DE-OS 33 37 232) wird daher mittels eines Hebemechanismus die vordere Sitzkante beim Crash angehoben, so daß diese kurz vor dem Auftreffen des beim Frontalaufprall nach vorn beschleunigten Insassens in der unfalltechnisch optimalen Position liegt. Hier zu weist der Hebemechanismus einen karosseriefesten Luftzylinder auf, in dem beim Crash schlagartig ein Druck aufgebaut wird. Die Druckluft wird über eine Druck luftleitung einem im Sitzkissen integrierten Luft kissen zugeführt. Das Luftkissen wird aufgeblasen und bewirkt eine Anhebung der Vorderkante des Sitz kissens.In a known belt holding device at the beginning mentioned type (DE-OS 33 37 232) is therefore by means of the front edge of a seat during a crash raised so that this shortly before the impact of the In the event of a frontal impact, the occupant accelerates forward is in the optimal position in terms of accident technology. Here the lifting mechanism assigns a body-fixed one Air cylinder in which there is a sudden pressure in the event of a crash is built up. The compressed air is over a pressure air duct an air integrated in the seat cushion pillow fed. The air cushion is inflated and raises the front edge of the seat kissing.
Die Wirksamkeit der Rückhaltevorrichtung hängt aber auch entscheidend von der Lage des Verzweigungs punktes zwischen dem Diagonal- und Beckengurtabschnitt des Sicherheitsgurtes in Relation zum Hüftknochen des Sitzenden ab. Bei manchen Fahrzeugsitzen, ins besondere bei Fondsitzen, liegt dieser, bei angelegtem Sicherheitsgurt am Gurtschloß sich ausbildende Ver zweigungspunkt aus anderen zwingenden Gründen, z.B. wegen der guten Zugänglichkeit des Gurtschlosses, nicht in einer optimal tiefen Position, so daß die Rückhaltevorrichtung trotz der auf optimalem Niveau liegenden Stützfläche des Sitzkissens ihre maximale Wirkung nicht entfalten kann.The effectiveness of the restraint depends, however also crucial from the location of the branch point between the diagonal and lap belt section the seat belt in relation to the hip bone of the seated. In some vehicle seats, ins especially with rear seats, this is when the seat is on Seat belt on the buckle ver branch point for other imperative reasons, e.g. because of the good accessibility of the buckle, not in an optimally deep position, so that the Restraint device despite the optimal level lying support surface of the seat cushion their maximum Effect can not develop.
Der Erfindung liegt die Aufgabe zugrunde, eine Rückhalte vorrichtung der eingangs genannten Art mit verbesserter Rückhaltewirkung zu schaffen.The invention has for its object a retention device of the type mentioned with improved To create restraint.
Die Aufgabe ist bei einer Rückhaltevorrichtung der im Oberbegriff des Anspruchs 1 angegebenen Gattung erfin dungsgemäß durch die Merkmale im Kennzeichnungsteil des Anspruchs 1 gelöst.The task is with a restraint in Preamble of claim 1 specified genus inventions according to the characteristics in the labeling part of claim 1 solved.
Die erfindungsgemäße Rückhaltevorrichtung hat den Vor teil, daß unabhängig von den Plaziermöglichkeiten des Gurtschlosses am Sitzunterrahmen oder Karosserieboden im Crashfall der Verzweigungspunkt zwischen Diagonal- und Beckengurtabschnitt immer so tief liegt, daß in Verbindung mit der um einen vorgegebenen Betrag angehobenen Stützfläche eine optimale Insassen kinematik erzielt wird. Die erfindungsgemäße Rückhal tevorrichtung ist vor allem bei Fahrzeugsitzen ein setzbar, die aus Sitzkomfortgründen eine niedrige Sitzvorderkante und eine hohe Gurtschloßlage auf weisen, wie dies bei Fondsitzen mit durchgehender Bank der Fall ist.The restraint device according to the invention has the front part that regardless of the placement options of the Belt buckle on the seat subframe or body floor in the event of a crash, the branching point between diagonal and lap belt section is always so low that in Link with the by a predetermined amount raised support surface an optimal occupant kinematics is achieved. The backing according to the invention The device is mainly used in vehicle seats settable, a low for seating comfort reasons Front edge of seat and a high belt buckle position point, as is the case with rear seats with continuous Bank is the case.
Vorteilhafte Ausführungsformen der Erfindung mit zweckmäßigen Weiterbildungen ergeben sich aus den Ansprüchen 2-7.Advantageous embodiments of the invention with Appropriate further training results from the Claims 2-7.
Eine vorteilhafte Ausführungsform der Erfindung ergibt sich dabei aus Anspruch 2. Durch einen solchen Sitz keil wird der angegurtete Fahrzeuginsasse bei Crash nach kurzem Federweg des gefederten Sitzpolsters abgefangen, so daß das Gesäß des Fahrzeuginsassens nicht weiter in das Sitzkissen eintauchen kann. Durch die Deformierbarkeit des Sitzkeils wird ein Teil der Bewegungsenergie des Fahrzeuginsassens zusätzlich ab gebaut. Als deformierbare Sitzkeile können Blechkon struktionen, umschäumte Rohrkonstruktionen, Kunststoff schalen etc. verwendet werden.An advantageous embodiment of the invention results itself from claim 2. By such a seat the belted vehicle occupant becomes wedge in the event of a crash after a short spring travel of the sprung seat cushion intercepted so that the buttocks of the vehicle occupant cannot immerse further in the seat cushion. By the deformability of the seat wedge becomes part of the Kinetic energy of the vehicle occupant additionally built. As deformable seat wedges, sheet metal con structures, foamed pipe constructions, plastic bowls etc. can be used.
Die Erfindung ist anhand von in der Zeichnung darge stellten Ausführungsbeispielen im folgenden näher be schrieben. Es zeigen jeweils in schematischer Darstel lung:The invention is based on Darge in the drawing provided exemplary embodiments in the following wrote. They each show a schematic representation lung:
Fig. 1 und 2 jeweils eine Seitenansicht eines Fahrzeug sitzes mit einer Rückhaltevorrichtung für einen Fahrzeuginsassen gemäß einem ersten und zweiten Ausführungsbeispiel. Fig. 1 and 2 are a side view of a vehicle seat with a retaining device for a vehicle occupant according to a first and second embodiment.
Der in Fig. 1 schematisch skizzierte Fahrzeugsitz weist in bekannter Weise ein Sitzkissen 10 und eine Rückenlehne 11 auf. Wie üblich besteht das Sitzkissen 10 aus einem gefederten Sitzpolster 12, das auf einem Sitzunterrahmen 13, meist in Form einer Sitzschale, befestigt ist.The vehicle seat schematically outlined in FIG. 1 has a seat cushion 10 and a backrest 11 in a known manner. As usual, the seat cushion 10 consists of a sprung seat cushion 12 , which is attached to a seat frame 13 , usually in the form of a seat shell.
Die dem Fahrzeugsitz zugeordnete Rückhaltevorrichtung für einen auf dem Fahrzeugsitz plazierten Fahrzeug insassen weist einen Sicherheitsgurt 14 und einen Gurtver schluß 15 zur Verriegelung des Sicherheitsgurtes nach Anlegen durch den Fahrzeuginsassen auf. Von dem zwei teiligen, aus Einsteckzunge 16 und Aufnahmeteil 17 beste henden Gurtverschluß 15 ist die Einsteckzunge 16 am Sicherheitsgurt 14 und das Aufnahmeteil 17 am Sitzunter rahmen 13 festgelegt. Bei in das Aufnahmeteil 17 ein gesteckterEinsteckzunge 16 wird der Sicherheitsgurt 14 von dem Gurtverschluß 15 in zwei Gurtabschnitte, den Diagonalgurt 18 und den Beckengurt 19, unterteilt.The associated with the vehicle seat restraint for a vehicle seated on the vehicle occupant has a seat belt 14 and a belt buckle 15 for locking the seat belt after being put on by the vehicle occupant. Of the two-part, from tongue 16 and receiving part 17 best existing belt buckle 15 , the tongue 16 on the seat belt 14 and the receiving part 17 on the seat frame 13 is fixed. When the tongue 16 is inserted into the receiving part 17 , the seat belt 14 is divided by the belt buckle 15 into two belt sections, the diagonal belt 18 and the lap belt 19 .
Zu der Rückhaltevorrichtung gehört noch ein Hebemecha nismus 20 zum Anheben des Abstützniveaus im vorderen Endbereich 21 des Sitzkissens 10 bei Frontalaufprall. Hierzu ist im Sitzkissen 10 ein deformierbarer Sitz keil 22 vorgesehen, der um einen zum hinteren Sitz ende 37 verlagerten Drehpunkt 23 am Sitzunterrahmen 13 schwenkbar gehalten ist und eine zum vorderen Sitzende 24 hin ansteigende Keilfläche 25 aufweist. Der Sitz keil 22 kann als Blechkonstruktion, als umschäumte Rohrkonstruktion oder als Kunststoffschale ausgebildet sein. Zur Verstellung des Sitzkeils 22 zwecks Anheben des vorderen Endbereichs 21 des Sitzkissens 10 greift der Hebemechanismus 20 an dem dem vorderen Sitzende 24 zugekehrten Vorderende 26 des Sitzkeils 22 an. To the retention device still includes a Hebemecha mechanism 20 for raising the support level in the front end region 21 of the seat cushion 10 in the event of a frontal impact. To this end a deformable seat is provided a wedge 22 in the seat cushion 10, the displaced at one end to the rear seat 37 pivot point is pivotally supported on the seat frame 13 and 23 comprises a seat to the front end 24 toward wedge surface rising 25th The seat wedge 22 can be designed as a sheet metal construction, as a foam-encased tubular construction or as a plastic shell. In order to adjust the seat wedge 22 for the purpose of lifting the front end region 21 of the seat cushion 10 , the lifting mechanism 20 engages the front end 26 of the seat wedge 22 facing the front seat end 24 .
Der Hebemechanismus 20 weist ein scherenartiges Spreizgetriebe 27 mit zwei über ein Gelenk 28 verbun denen Schenkeln 29, 30 und einen pyrotechnischen Linearantrieb 31 auf. Das Spreizgetriebe 27 ist an dem freien Ende des einen Schenkels 29 nahe dem vorderen Ende des Sitzunterrahmens 13 an diesem schwenkbar gelagert und mit dem freien Ende des anderen Schenkels 30 an dem vorderen Ende 26 des Sitzkeils 22 angelenkt. Das frei bewegliche Gelenk 28 ist mit dem Linearantrieb 31 gekoppelt und so angeordnet, daß bei Einwirken einer Zugkraft auf das Gelenk 28 die Schenkelaufspreizrichtung des Spreiz getriebes 27 zum vorderen Sitzende 24 hin gerichtet ist.The lifting mechanism 20 has a scissor-like expansion gear 27 with two legs 29 , 30 connected via a joint 28 and a pyrotechnic linear drive 31 . The expansion gear 27 is pivotally mounted on the free end of one leg 29 near the front end of the seat subframe 13 and articulated with the free end of the other leg 30 on the front end 26 of the seat wedge 22 . The freely movable joint 28 is coupled to the linear drive 31 and arranged so that when a tensile force acts on the joint 28, the leg expansion direction of the expansion gear 27 is directed towards the front seat end 24 .
Der in Fig. 1 nur schematisch skizzierte pyrotech nische Linearantrieb 31 ist bekannt und z.B. in der DE-PS 23 49 891 detailliert beschrieben. Prinzipiell besteht er aus einem Zylinder 32, in welchem ein Kolben 33 mittels einer im Crashfall gezündeten pyrolytischen Treibladung 34 in Axialrichtung des Zylinders 32 antreibbar ist. Der Kolben 33 ist über ein erste Zugelement 35, z.B. Stahlseil, mit dem Gelenk 28 des Spreizgetriebes 27 verbunden. Der etwa horizontal ausgerichtete Zylinder 32 ist an dem Sitz unterrahmen 13 gelenkig befestigt, damit das Zugelement 35 bei der mit Aufspreizung der Schenkel 29 des Spreiz getriebes 27 verbundenen Schwenkbewegung des Gelenks 28 geradlinig ausgerichtet bleibt.The only schematically outlined in Fig. 1 pyrotechnic linear actuator 31 is known and described in detail, for example, in DE-PS 23 49 891. In principle, it consists of a cylinder 32 in which a piston 33 can be driven in the axial direction of the cylinder 32 by means of a pyrolytic propellant charge 34 ignited in the event of a crash. The piston 33 is connected to the joint 28 of the expansion gear 27 via a first tension element 35 , for example a steel cable. The approximately horizontally aligned cylinder 32 is articulated to the seat subframe 13 so that the tension element 35 remains aligned with the pivoting movement of the joint 28 associated with the spreading of the legs 29 of the expansion gear 27 .
An dem Gelenk 28 ist ein zweites Zugelement 36 in Form eines Stahlseiles befestigt und mit dem Aufnahmeteil 17 des Gurtver schlusses 15 verbunden. Statt an dem Gelenk 28 kann das zweite Zugelement 36 auch unmittelbar am ersten Zugele ment 35 oder am Kolben 33 selbst befestigt sein. Nahe dem hinteren Sitzende 37 ist am Sitzunter rahmen 13 eine Umlenkrolle 38 drehbar gelagert. Die Umlenkrolle 38 ist dabei so angeordnet, daß das zweite Zugelement 36 an dem Aufnahmeteil 17 des Gurt verschlusses 15 mit einer Zugkraft angreift, die schräg nach unten und wegweisend von dem vorderen Sitzende 24 gerichtet ist.At the joint 28 , a second tension element 36 is fastened in the form of a steel cable and connected to the receiving part 17 of the Gurtver circuit 15 . Instead of the joint 28 , the second tension element 36 can also be attached directly to the first tension element 35 or to the piston 33 itself. Near the rear seat end 37 , a guide roller 38 is rotatably mounted on the seat frame 13 . The deflection roller 38 is arranged so that the second tension element 36 on the receiving part 17 of the belt fastener 15 engages with a tensile force which is directed obliquely downward and pointing away from the front seat end 24 .
Die Wirkungsweise der vorstehend beschriebenen Rückhaltevorrichtung ist wie folgt:The operation of those described above The restraint is as follows:
Im normalen Betriebsfall stützt sich das Sitzpolster 12 des Sitzkissens 10 federnd auf dem Sitzkeil 22 ab. Bei Belastung des Sitzkissens 10 nimmt der schwenkbare Sitzkeil 22 an der Einfederung des Sitzpolsters 12 teil und wird von dem auf dem Sitzkissen 10 plazierten Fahr zeuginsassen nicht als unangenehm harte Kante empfun den.In normal operation, the seat cushion 12 of the seat cushion 10 is supported resiliently on the seat wedge 22 . When the seat cushion 10 is loaded, the pivotable seat wedge 22 takes part in the deflection of the seat cushion 12 and is not perceived by the vehicle occupant placed on the seat cushion 10 as an uncomfortably hard edge.
Bei Frontalaufprall des Fahrzeugs wird über einen auf die extreme Fahrzeugverzögerung ansprechenden Sensor die pyrotechnische Treibladung 34 des Linearantriebs 31 gezündet. Durch die Expansion des Gases wird der Kol ben 33 schlagartig im Zylinder 32 in Richtung zum vor deren Sitzende 24 hin beschleunigt. Über das erste Zugelement 35 wird das Spreizgetriebe 27 in die in Fig. 1 strichliniert gezeichnete Stellung überführt. Durch die Schenkelaufspreizung des Spreizgetriebes 27 wird der Sitzkeil 22 an seinem Vorderende 26 um die Höhe A in Vertikalrichtung angehoben. Zugleich wird über das zweite Zugelement 36 der Gurtverschluß 15 um eine Wegstrecke B schräg nach unten in eine tiefere Position verlagert. Dadurch ist eine äußerst günstige Insassenkinematik erzielt, in welcher der Insasse tief in das Sitzkissen 10 hineingezogen wird und mit dem Gesäß auf die steil aufgerichtete Keilfläche 25 des Sitzkeils 22 mit sehr hochliegendem vorderen Ende auftrifft. Das Spreizgetriebe 27 ist so ausgebildet, daß es in seiner Spreizstellung sperrt und der Sitz keil 22 damit dem Insassen einen erheblichen Rückhalte widerstand entgegensetzt. Damit ist zuverlässig ver hindert, daß der angegurtete Insasse unter dem Sicher heitsgurt hindurchrutscht und der Beckengurtabschnitt 19 am Unterleib hochrutscht und sich hier unter die Rippen schiebt.In the event of a frontal impact of the vehicle, the pyrotechnic propellant charge 34 of the linear drive 31 is ignited by a sensor which responds to the extreme vehicle deceleration. Due to the expansion of the gas, the piston 33 is suddenly accelerated in the cylinder 32 in the direction toward the front end 24 thereof. The expansion gear 27 is transferred to the position shown in broken lines in FIG. 1 via the first tension element 35 . Due to the spreading of the legs of the expansion gear 27 , the seat wedge 22 is raised at its front end 26 by the height A in the vertical direction. At the same time, the belt fastener 15 is shifted obliquely downward by a distance B into a lower position via the second tension element 36 . This results in extremely favorable occupant kinematics, in which the occupant is drawn deep into the seat cushion 10 and strikes the buttocks on the steeply erected wedge surface 25 of the seat wedge 22 with the front end lying very high. The expansion gear 27 is designed so that it locks in its spread position and the seat wedge 22 so that the occupant resists considerable restraint. This reliably prevents ver that the belted occupant slips under the seat belt and the lap belt portion 19 slides up on the abdomen and slides under the ribs here.
Das in Fig. 2 dargestellte weitere Ausführungsbeispiel einer Rückhaltevorrichtung stimmt weitgehend mit der in Fig. 1 erläuterten Rückhaltevorrichtung überein, so daß gleiche Bauteile der Rückhaltevorrichtung mit gleichen Bezugszeichen versehen sind. Der einzige Unterschied besteht in der Ausbildung des Hebe mechanismus 120, dessen Bezugszeichen daher um 100 gegenüber gleichartigen Bezugszeichen in Fig. 1 erhöht sind. Der Hebemechanismus 120 besteht wie derum aus einem identisch ausgebildeten Spreizge triebe 127 und einem pyrotechnischen Antrieb, hier jedoch einem Rotationsantrieb 139 mit Aufwickelrolle 140. Auf der Aufwickelrolle 140 werden die beiden als Stahlseile ausgebildeten Zugelemente 135 und 136 aufgewickelt. Das Spreizgetriebe 27 ist so angeordnet, daß die Schenkelspreizrichtung zum hinteren Sitzende 37 hin gerichtet ist. Der Rotationsantrieb 139 ist nahe dem hinteren Sitzende 37 an dem Sitzunterrahmen 13 so ange ordnet, daß das auf die Aufwickelrolle 140 auflaufende zweite Zugelement 136 auf den Gurtverschluß 15, von dem in Fig. 2 nur das Aufnahmeteil 17 dargestellt ist, eine Zugkraft ausübt, die - identisch wie in Fig. 1 - schräg nach unten zum hinteren Sitzende 37 weisend gerichtet ist.The further exemplary embodiment of a restraint device shown in FIG. 2 largely corresponds to the restraint device explained in FIG. 1, so that the same components of the restraint device are provided with the same reference numerals. The only difference is the design of the lifting mechanism 120 , the reference numerals of which are therefore increased by 100 compared to similar reference numerals in FIG. 1. The lifting mechanism 120 again consists of an identically designed expansion gear 127 and a pyrotechnic drive, but here a rotary drive 139 with a winding roller 140 . The two tension elements 135 and 136 designed as steel cables are wound on the winding roller 140 . The expansion gear 27 is arranged so that the leg expansion direction is directed towards the rear seat end 37 . The rotary drive 139 is arranged near the rear seat end 37 on the seat subframe 13 so that the second pulling element 136 running onto the take-up reel 140 onto the belt buckle 15 , of which only the receiving part 17 is shown in FIG. 2, exerts a tensile force which - Identical as in Fig. 1 - directed obliquely downward toward the rear seat end 37 .
Im Crashfall treibt der pyrotechnische Rotations antrieb 139 die auf seiner Antriebswelle drehfest sitzende Aufwickelrolle 140 in Fig. 2 im Uhrzeiger sinn an. Beide Zugelemente 135 und 136 werden auf gewickelt. Das an dem Gelenk 128 des Spreizgetriebes 127 angreifende erste Zugelement 135 bewirkt damit in gleicher Weise eine Aufspreizung des Spreizgetrie bes 127 und eine Anhebung des schwenkbar am Sitzunter rahmen 13 gehaltenen Sitzkeils 22. Das am Aufnahmeteil 17 des Gurtverschlusses 15 angreifende zweite Zug element 136 bewirkt eine Verlagerung des Gurtverschlus ses 15 nach unten in Richtung zum Sitzunterrahmen 13.In the event of a crash, the pyrotechnic rotary drive 139 drives the take-up reel 140 , which is rotationally fixed on its drive shaft, in the clockwise direction in FIG. 2. Both tension elements 135 and 136 are wound on. The acting on the hinge 128 of the expansion gear 127 first pull element 135 thus causes a spreading of the expansion gear bes 127 and an increase in the pivotally mounted on the seat subframe 13 seat wedge 22nd The attacking on the receiving part 17 of the belt buckle 15 second train element 136 causes a shift of the belt buckle ses 15 down towards the seat frame 13th
