Abstract

A safety mounting for a car seat belt has the belt secured to the seat itself, with the shoulder anchorage point (6) at one side near the top edge of the seat back. The seat back has rake control and is secured in its setting by a strut (8) set between guides (13) in the side of the squab and the seat back. The strut folds in the centre (9) to allow rake adjustment, using a hand release (15). A spring (14) pulls the strut into the rigid locking position in which it provides full support for the seat back in impacts. The seat belt fittings moves with the seat adjustment.

Personenkraftfahrzeuge Die Erfindung bezieht sich auf einen Sitz für Fahrzeuge, insbesonderte Personenkraftfahrzeuge, der in dem Oberbegriff des Patentanspruchs 1 angegebenen Art. Passenger vehicles The invention relates to a seat for vehicles, in particular passenger vehicles, which are included in the generic term of Claim 1 specified type.

Wenn der Wunsch besteht, das der Schulter eines Fahrzeuginsassen zugeordnete Ende einer Sicherheitsgurtanordnang an der Oberkante der Lehne eines Fahrzeugsitzes zu verankern, um auf diese Weise eine von der Stellung des Fahrzeugsitzes in dem Fahrzeug unabhängige, gleichbleibend gute Lage des Sicherheitsgurtes am Körper des Fahrzeuginsassen zu gewährleisten, dann ergeben sich Schwierigkeiten für die gefahrlose Aufnahme der bei einem RUckhaltefall auftretenden Gurtkräfte in der Sitzlehne. Insbesondere bei Fahrzeugsitzen, deren Sitzlehnen verschwenkbar sind, treten so erhebliche Probleme auf, daß eine derartige Ausführung bisher jedenfalls serienmäßig nicht verwirklicht worden ist.If there is a desire, the one assigned to the shoulder of a vehicle occupant End of a seat belt assembly on the upper edge of the backrest of a vehicle seat to anchor in this way one of the position of the vehicle seat in the Vehicle-independent, consistently good position of the seat belt on the body of the To ensure vehicle occupants, then difficulties arise for the safe Absorption of the belt forces occurring in the case of restraint in the seat back. In particular In the case of vehicle seats, the seat backs of which can be pivoted, considerable problems arise on that such a design has so far not been realized in series in any case has been.

Die der vorliegenden Erfindung zugrundeliegende Aufgabe besteht daher darin, einen Sitz für Fahrzeuge der eingangs genannten Bauart zu schaffen, der für die Aufnahme des Schulterbefestigungspunktes der Sicherheitsgurtanordnung an der Oberkante der Sitzlehne geeignet ist. Die Konstruktion soll möglichst einfach und kostengünstig sein und zudem eine neue Möglichkeit der Verriegelung der Sitzlehne in den verschiedenen Stellungen gegenüber dem Sitzpolster ermöglichen.The object on which the present invention is based therefore exists therein, a seat for vehicles of the type mentioned to create the one for receiving the shoulder attachment point of the seat belt assembly at the top of the seat back is suitable. The construction should be as simple as possible and be inexpensive and also a new way of locking the seat back in the various positions in relation to the seat cushion.

Die Lösung dieser Aufgabe erfolgt gemäß dem Kennzeichen des Patentanspruchs 1. Dabei wird davon ausgegangen, daß die bei einem Rückhaltefall in die Oberkante der Sitz lehne eingeleiteten Gurtrückhaltekräfte über das zwischen der Sitzlehne und dem Sitzpolster angeordnete Gestänge direkt in das Sitzpolster und von dort in den Fahrzeugboden übertragen wird.This problem is solved in accordance with the characterizing part of the patent claim 1. It is assumed that in the event of a restraint in the upper edge The seat back restraint forces introduced via the between the seat back and the seat cushion arranged linkage directly into the seat cushion and from there is transferred to the vehicle floor.

Gemäß einer bevorzugten Aus führungs form der Erfindung soll das Gestänge als Kniehebel mit einem mittleren, eine Verschwenkung um einen begrenzten Schwenkwinkel erlaubenden Gelenk ausgebildet sein, so daß durch Verschwenkung des Kniehebels aus seiner Ruhestellung heraus die Festlegung der Kniehebelenden in den Führungen des Sitzpolsters und/oder der Sitzlehne zur Verstellung in eine andere Neigungsstellung der Sitzlehne gegenüber dem Sitzpolster gelöst werden kann.According to a preferred embodiment of the invention, the linkage as a toggle lever with a middle, a pivoting around a limited pivot angle Allowing joint be designed so that by pivoting the toggle lever its rest position out the definition of the toggle lever ends in the guides of the Seat cushion and / or the seat back for adjustment in a different inclination position the seat back can be released from the seat cushion.

Weitere Ausgestaltungen der Erfindung ergeben sich gemäß den Unteransprüche.Further refinements of the invention result from the subclaims.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung in schematischer Darstellungsweise gezeigt, das im folgenden näher erläutert wird. Die Zeichnung zeigt eine Seitenansicht eines Pahrzeugsitzes mit der erfindungsgemäßen Ausgestaltung.In the drawing, an embodiment of the invention is in schematic Representation shown, which is explained in more detail below. The drawing shows a side view of a vehicle seat with the embodiment according to the invention.

Dabei wird mit 1 der Fahrzeugsitz insgesamt, mit 2 dessen Sitzpolster und mit 3 dessen gegenüber dem Sitzpolster in der Neigung um einen Schwenkpunkt 4 verstellbare Sitzlehne bezeichnet. 5 deutet einen dem Sitz 1 zugeordneten Sicherheitsgurt an, dessen der Schulter des hier nicht dargestellten Fahrzeuginsassen zugeordnetes Ende an einem Befestigungspunkt 6 an der Oberkante der Sitz lehne 3 verankert ist. Diese Verankerung kann sowohl in der Weise erfolgen, daß das Ende des Gurtes mittels eines üblichen Gurtbeschlages an der Oberkante der Lehne 3 befestigt ist als auch in der Weise, daß an der Oberkante der Sitzlehne 3 eine ein Ende des Sicherheitsgurtes aufwickelnde, ebenfalls an sich bekannte Gurtaufickeivorrichtung gehalten ist.With 1 the vehicle seat becomes overall, with 2 its seat cushion and with 3 of its opposite to the seat cushion in the inclination about a pivot point 4 called adjustable seat back. 5 indicates a seat belt assigned to the seat 1 at whose the shoulder of the vehicle occupant, not shown here associated end at a fastening point 6 on the upper edge of the seat back 3 is anchored. This anchoring can be done in such a way that the end of the belt attached to the upper edge of the backrest 3 by means of a conventional belt fitting is as well as in such a way that at the upper edge of the seat back 3 one end of the Belt winding device that winds up the seat belt, also known per se is held.

Um die Sitzlehne 3 nun von der Ubertragung der bei einem Rückhalbefall auftretenden Gurtkräfte weitgehend zu entlasten, ist ein die Sitzlehne 3 mit dem Sitzpolster 2 verbindendes Stützgestänge in Form eines Kniehebels 7 vorgesehen. Dieser Kniehebel besteht aus zwei Hebelarmen 8a und 8b, die mittels eines mittleren Gelenkes 9 um einen begrenzten Schwenkwinkel um die gestreckte Lage herum gegeneinander verschwenkbar sind. Die beiden voneinander abgewandten Enden 10 und 12 der beiden Hebelarme 8a und 8b sind in seitlichen Längsführungen 11 und 13 an dem Sitzpolster 2 bzw. an der Sitzlehne 3 in der Weise geführt, daß sie in verschiedenen Stellungen durch eine hier nicht weiter gezeigte Klemm- oder Einrastvorrichtung festlegbar sind. Dabei ist es auch durchaus denkbar, daß nur eines der beiden Enden 10 und 12 in einer Führung verschiebbar ist, während das andere Ende feststeht.To the seat back 3 now from the transmission of a back half case To largely relieve occurring belt forces, the seat back 3 with the Support rods connecting the seat cushion 2 in the form of a toggle lever 7 are provided. This toggle lever consists of two lever arms 8a and 8b, which by means of a middle Joint 9 against each other by a limited pivot angle around the extended position are pivotable. The two opposite ends 10 and 12 of the two Lever arms 8a and 8b are in lateral longitudinal guides 11 and 13 on the seat cushion 2 or on the seat back 3 in such a way that they are in different positions can be fixed by a clamping or latching device not shown here are. It is also quite conceivable that only one of the two ends 10 and 12 is displaceable in a guide, while the other end is fixed.

In der Zeichnung ist der Kniehebel 7 in seiner Ruhestellung gezeigt, in die er ständig von einer Feder 14 gedrängt wird. Dabei wird von den beiden Hebelarmen 8a und 8b, sowie von den zwischen dem Gelenkpunkt 4 uniden Enden 10 bzw. 12 des Kniehebels 7 liegenden Teile des Sitzpolsters bzw. der Sitzlehne ein ungleichmäßiges Viereck gebildet, bei dem der von den beiden Hebelarmen 8a und 8b des Kniehebels eingeschlossene Winkel am Gelenk 9 kleiner als 1800 ist.In the drawing, the toggle lever 7 is shown in its rest position, into which it is constantly urged by a spring 14. This is done by the two lever arms 8a and 8b, as well as from the unid between the hinge point 4 ends 10 and 12 of the Knee lever 7 lying parts of the seat cushion or the seat back an uneven Formed a square in which the two lever arms 8a and 8b of the toggle lever included angle at the joint 9 is less than 1800.

Zur Verstellung des Kniehebels aus dieser der Verriegelungsstellung der Sitzlehne 3 gegenüber dem Sitzpolster 2 entsprechenden Ruhestellung ist eine beispielsweise als Zugseil ausgebildete Handhabe 15 vorgesehen, bei deren Betätigung in Richtung auf den Dreipunkt 4 hin der sich zwischen den beiden Hebelarmen 8a und 8b des Kniehebels 7 befindende Winkel in Richtung auf die gestreckte Lage der beiden Hebelarme hin vergrößert wird. Durch diese Verstellung des Kniehebels aus seiner Ruhelage heraus wird gleichzeitig die Festlegung des oder der Endpunkte 10 bzw. 12 des Kniehebels 7 in den Führungen 11 bzw. 13 gelöst, so daß diese nun in der bzw. den Führungen unter Verstellung der Neigung der Sitzlehne 3 gegenüber dem Sitzpolster 2 frei verschoben werden können. Bei Freigabe der Handhabe 15 würde die in dem Ausführungsbeispiel als Druckfeder ausgebildete Feder 14 den Kniehebel wieder in seine Ruhestellung zurückdrtokenj in der die Endpunkte 10 und 12 des Kniehebels wieder festgelegt sind.To adjust the toggle lever from this locking position the seat back 3 relative to the seat cushion 2 is a corresponding rest position Handle 15 designed as a pull rope, for example intended, when actuated in the direction of the three-point 4 that is between the two Lever arms 8a and 8b of the toggle lever 7 located angle in the direction of the stretched Position of the two lever arms is increased. Through this adjustment of the knee lever at the same time the determination of the end point (s) is made from its rest position 10 and 12 of the toggle lever 7 released in the guides 11 and 13, so that these now in the guide or guides while adjusting the inclination of the seat back 3 opposite the seat cushion 2 can be moved freely. When the handle 15 is released the spring 14, designed as a compression spring in the exemplary embodiment, the toggle lever back to its rest position in which the end points 10 and 12 of the toggle lever are set again.

Der Kniehebel braucht nur auf der Seite des Fahrzeugsitzes angebracht zu werden, an der sich auch der der Schulter des Fahrzeuginsassen zugeordnete Befestigungspunkt des Sicherheitsgurtes befindet. Dies kann entweder auf der Fahrzeugaußenseite oder aber auch auf der der Fahrzeugmitte zugewandten Seite des Sitzes sein. Durch die in der Zeichnung gezeigte Einrichtung kann zudem die bisher übliche Verstell- und Verriegelungsvorrichtung der Sitzlehnen gegenüber den Sitzpolstern entfallen.The knee lever only needs to be attached to the side of the vehicle seat at which the fastening point assigned to the shoulder of the vehicle occupant is also located seat belt is located. This can either be on the outside of the vehicle or but also be on the side of the seat facing the center of the vehicle. Through the The device shown in the drawing can also use the usual adjustment and There is no need for a locking device for the seat backs with respect to the seat cushions.
