Abstract
Description
Die Erfindung betrifft einen Kindersitz für Kraftfahrzeuge mit Sicherheitsgurten zum Zurückhalten des Körpers bei Auffahr- od. dgl. Unfällen, um schwere Körperverletzungen zu vermeiden.The invention relates to a child seat for motor vehicles with seat belts to restrain the body Collision or the like. Accidents to serious injuries avoid.
Bei den bekannten Kindersitzen sind die Schultergurte des Rückhaltesystems starr mit der Rückenlehne verbunden. Im Falle eines Unfalls wird die kinetische Energie des Ober körpers des Kindes durch die Schultergurte abgefangen. Eine umfangreiche Untersuchung in jüngster Zeit (Test, 1990, H. 4, S. 35 ff) kam zu dem Ergebnis, daß der Kopf und die Halswirbelsäule der Kinder am stärksten gefährdet sind und daß die Kinder die Belastungen bei einem Unfall viel weniger zu ertragen in der Lage sind als Erwachsene.In the known child seats, the shoulder straps are the Restraint system rigidly connected to the backrest. in the In the event of an accident, the kinetic energy of the waiter child's body is caught by the shoulder straps. A extensive recent investigation (Test, 1990, H. 4, p. 35 ff) came to the conclusion that the head and the Children's cervical spine are most at risk and that the child's loads in an accident are much less are able to endure as adults.
Nach Berichten über Unfälle von Kleinkindern sollen Genick brüche und Querschnittslähmungen vorgekommen sein, wenn sie in Kindersitzen mit Hosenträgergurten untergebracht waren. Solche Unfallfolgen werden darauf zurückgeführt, daß der Oberkörper des Kindes zu fest umschnürt ist bzw. an der Rückenlehne des Sitzes festgehalten wird, und der im Ver hältnis zum übrigen Körper noch sehr schwere Kopf bei einem Aufprall des Fahrzeugs zu plötzlich nach vorn schnellt, der Oberkörper sich jedoch nicht im gleichen Maße mitbewegt. Weiterhin kommt hinzu, daß der Kopf und Oberkörper im An schluß an die Vorwärtsbewegung eine Rückwärtsbewegung aus führen, durch die ebenfalls Schäden verursacht werden können.According to reports of accidents involving young children, neck should be fractures and paraplegia have occurred if they were placed in child seats with harness belts. Such consequences of the accident are attributed to the fact that the The child's torso is tied too tightly or on the Backrest of the seat is held, and the Ver relationship to the rest of the body still very heavy head in one Impact of the vehicle suddenly jumps forward However, the upper body does not move to the same extent. In addition, the head and upper body in the An exclude a backward movement from the forward movement cause damage can.
Der Erfindung liegt die Aufgabe zugrunde, Kindersitze, ins besondere Kleinkindersitze der in Betracht kommenden Art so zu verbessern, daß das Verletzungsrisiko in bezug auf den Oberkörper und insbesondere die Halswirbelsäule und den Kopf des Kindes auf ein Mindestmaß gesenkt wird.The invention has for its object child seats ins special toddler seats of the type under consideration to improve the risk of injury in relation to the Upper body and especially the cervical spine and head of the child is reduced to a minimum.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorge schlagen, den mit die Schultern des Kindes übergreifenden Hosenträgergurten ausgestatteten Kindersitz in der Weise auszubilden, daß zwischen den oberen Enden der Gurte und deren Befestigungspunkten an der Rückenlehne wenigstens ein Federkraftspeicher angeordnet ist. Dieser ist vorzugsweise einstellbar ausgebildet, um seine Dämpfungswirkung dem Gewicht bzw. der Masse des Oberkörpers des Kindes in ein facher Weise anpassen zu können.To solve this problem, according to the invention beat that overlapping the child's shoulders Child seat belts equipped in the manner train that between the top ends of the straps and whose attachment points on the backrest at least one Spring energy store is arranged. This is preferred adjustable to its damping effect Weight or mass of the child's upper body in one to be able to adjust
Durch diese erfindungsgemäß vorgeschlagene Maßnahme wird erreicht, daß im Falle eines Auffahr- od. dgl. Unfalls der Oberkörper des Kindes dem Vorschnellen des relativ schweren Kopfes folgen kann und dessen Vorwärtsbewegung progressiv verzögert wird, so daß das plötzliche Abknicken der Hals wirbelsäule weitestgehend gemildert wird und die daraus resultierenden Schäden auf ein Mindestmaß reduziert werden.Through this measure proposed according to the invention achieved that in the event of a drive-up or the like Upper body of the child rushing to the relatively heavy Head can follow and its forward movement progressively is delayed, causing the sudden kinking of the neck spine is largely mitigated and the resulting resulting damage can be reduced to a minimum.
Eine weitere Verbesserung eines derart ausgebildeten Kinder sitzes ist dadurch erreichbar, daß man zwischen dem Rücken des Kindes und der Rückenlehne des Sitzes ein im Querschnitt keilförmiges Stützpolster anordnet, welches auf- und abwärts bewegbar ist, und das bei sich nach vorn bewegendem Ober körper den keilförmigen Raum zwischen dem Rücken und dem Kopf und der Rückenlehne des Sitzes ausfüllen soll, um so ein plötzliches Zurückschleudern vor allem des Kopfes zu verhindern.Another improvement of such a trained child The seat can be reached by moving between the back of the child and the back of the seat a in cross section arranges wedge-shaped support pad, which is up and down is movable, and this with the upper moving forward body the wedge-shaped space between the back and the Head and backrest of the seat should fill, so a sudden fling back, especially of the head prevent.
Weitere Merkmale des erfindungsgemäß ausgebildeten Kinder sitzes gehen aus den Unteransprüchen wie auch aus der nach folgenden Beschreibung eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels hervor.Further features of the children trained according to the invention fit from the subclaims as well as from the following description of a schematic in the drawing illustrated embodiment.
Die Fig. 1 und 2 der Zeichnung zeigen je eine Seiten ansicht eines Kindersitzes gemäß der Erfindung in seiner prinzipiellen Konzeption, wobei in Fig. 1 das Kind in normaler Haltung und in Fig. 2 in seiner Haltung nach einem Unfall dargestellt ist. Figs. 1 and 2 of the drawing each show a side view of a child seat according to the invention in its basic design, in Fig. 1, the child is shown in a normal position and in Fig. 2 in its position after an accident.
Der Kindersitz 11 besteht üblicherweise aus einem Grund gestell 12 mit einem Sitz 13 und einer Rückenlehne 14, an welchen ein Sitzpolster 15, ein Lehnenpolster 16 und Seiten lehnen 17 befestigt sind.The child seat 11 usually consists of a base frame 12 with a seat 13 and a backrest 14 , to which a seat cushion 15 , a backrest cushion 16 and sides 17 are attached.
Das Rückhaltesystem für das auf dem Kindersitz 11 sitzende Kind besteht z. B. aus einem Beckengurt 18 und einem Hosen trägergurt 19, dessen beide oberen Abschnitte 20 die Schultern des Kindes übergreifen und dessen obere Enden 21 durch Schlitze 22 od. dgl. in der Rückenlehne 14 wie auch im Lehnenpolster 16 hindurchgeführt und nach unten umgelenkt und mit wenigstens einer Feder 23 oder einem aus mehreren Federn bestehenden Federsystem verbunden sind. Die Federn 23 sind ihrerseits an dem Grundgestell 12 oder an der Rücken lehne 14 befestigt.The restraint system for the child sitting on the child seat 11 consists, for. B. from a lap belt 18 and a trouser strap 19 , the two upper sections 20 overlap the shoulders of the child and the upper ends 21 through slots 22 or the like. In the backrest 14 as well as in the backrest pad 16 and deflected downwards and with at least one spring 23 or a spring system consisting of several springs are connected. The springs 23 are in turn attached to the base frame 12 or backrest 14 .
Im Falle eines Auffahr- od. dgl. Unfalls kippt der Oberkörper des Kindes, wie Fig. 2 erkennen läßt, nach vorn, wobei dessen Bewegung durch die aus den Schlitzen 22 in der Rückenlehne 14 gegen die Rückstellkraft der Federn 23 her ausgezogenen Gurtenden 21 progressiv abgebremst wird. In the event of a collision or the like. The upper body of the child tilts forward, as can be seen in FIG. 2, its movement progressively due to the belt ends 21 being pulled out of the slots 22 in the backrest 14 against the restoring force of the springs 23 is braked.
Die Federn 23 oder das an deren Stelle vorgesehene Feder system sollten hinsichtlich ihrer Federeigenschaften ein stell- oder verstellbar oder auch auswechselbar sein, damit sie eine solche Federkennlinie haben, die in bezug auf das Körpergewicht des Kindes, insbesondere die Masse des Ober körpers und des Kopfes einen optimalen Verlauf hat, um eine gewünschte Bewegungsdämpfung zu erreichen. Zwar wird der Kopf seiner großen Masse wegen ebenso wie bisher nach vorn geschnellt werden, jedoch ist das Abknicken der Halswirbel säule durch den ebenfalls, hierbei aber abgebremst nach vorn geschnellten Oberkörper gemildert.The springs 23 or the spring system provided in their place should be adjustable or adjustable or also interchangeable with regard to their spring properties, so that they have such a spring characteristic which is related to the body weight of the child, in particular the mass of the upper body and the head has an optimal course in order to achieve a desired movement damping. Because of its large mass, the head will be flipped forward as before, but the kinking of the cervical vertebrae is alleviated by the upper body, which also flies forward but is slowed down.
Um das Rückschnellen des Kopfes und des Oberkörpers des Kindes abzufangen, ist am oberen Ende der Rückenlehne 14 ein keilförmiges Stützpolster 24 angeordnet, das vertikal beweg lich ist und das dann zwischen den Kopf und den Oberkörper des Kindes und das Lehnenpolster 16 gezogen wird, wenn das Kind unfallbedingt nach vorn kippt. Hierzu dient eine Zug vorrichtung 25, die jeweils dann wirksam wird, wenn ein Unfall passiert ist. Die Zugvorrichtung 25 besteht bei spielsweise aus Bändern und an diesen angreifenden Federn und steht unter einer Vorspannung. Die Zugvorrichtung 25 bzw. das von dieser herabzuziehende keilförmige Stützpolster 24 wird beispielsweise dann ausgelöst und herabgezogen, wenn eine entsprechende Sperre von den nach vorn gezogenen Schultergurten aufgehoben worden ist.In order to intercept the snapback of the child's head and upper body, a wedge-shaped support cushion 24 is arranged at the upper end of the backrest 14 , which is vertically movable and which is then pulled between the child's head and upper body and the backrest cushion 16 when that Child tilts forward due to accident. For this purpose, a train device 25 is used , which is effective when an accident has occurred. The pulling device 25 consists, for example, of ribbons and springs acting on them and is under a prestress. The pulling device 25 or the wedge-shaped support pad 24 to be pulled down by it is triggered and pulled down, for example, when a corresponding lock has been lifted by the shoulder straps pulled forward.
