Description

Sitz für Kraftfahrzeuge, der bei Verzögerung des Fahrzeugs unter der Massenkraft relativ zu seinem Tragrahmen in Fahrtrichtung verschiebbar ist Die Erfindung bezieht sich auf einen Sitz für Kraftfahrzeuge, der bei Verzögerung des Fahrzeugs unter der Massenkraft relativ zu seinem Tragrahmen in Fahrtrichtung verschiebbar ist und im Bereich seiner hinteren Kante an einer nach vorn unten und in einem davorliegenden Bereich an einer nach vom oben verlaufenden Schrägfläche geführt ist, von denen die hintere Schrägfläche am Tragrahmen vorgesehen ist.Seat for motor vehicles, which when the vehicle decelerates under the Mass force is displaceable relative to its support frame in the direction of travel The invention refers to a seat for motor vehicles that is used when the vehicle decelerates Slidable under the inertia force relative to its support frame in the direction of travel is and in the area of its rear edge on one down in front and one in front of it Area is guided on an upward sloping surface, of which the rear inclined surface is provided on the support frame.

Ein Sitz dieser Art ist bekannt. Die Führungen am Tragrahmen sind bei diesem Sitz durch gekrümmte U-Schienen gebildet. In diesen U-Schienen, die beidseitig des Sitzes angeordnet sind, greifen je zwei beidseitig des Sitzes angebrachte Laufrollen ein. Je eine Laufrolle befindet sich hinten am Sitz. Je eine Laufrolle befindet sich etwa in dessen Mitte. Die Lehne und der eigentliche Sitz sind fest miteinander verbunden. Läuft der Sitz relativ zu seinem Tragrahmen vor, so kippt er nach rückwärts, wobei die Lehne mitkippt und im Ergebnis weiter nach hinten ragt als in Normalstellung. Das bedeutet, daß dieser Sitz beispielsweise nicht als rückwärtiger Sitz in einem Kraftfahrzeug verwendet werden kann, wo üblicherweise für das Rückwärtskippen der Lehne kein Raum ist. Die RollenU-Schienen-Führung dieses Sitzes hat ferner den Nachteil, daß man den Sitz nicht ohne weiteres, was bei der Innenreinigung des Fahrzeugs erforderlich ist, vom Tragrahmen abheben kann. Auch können sich die Rollen in ihren Führungen unter Umständen verklemmen, wenn nämlich der Sitz gegenüber dem Tragrahmen verkantet wird. Da die vorderen Laufrollen etwa im Mittelbereich an dem Sitz angeordnet sind und praktisch so angeordnet sein müssen, wenn die Führungsschienen nicht weit über die Vorderkanten des Sitzes hinaus verlängert werden sollen, muß überdies der Schwerpunkt von, Sitz und Person, damit eine sichere Wirkungsweise gewährleistet ist, relativ weit hinten liegen, was wohl auch der Grund dafür ist, daß Rücklehne und eigentlicher Sitz aneinander befestigt sind.A seat of this type is known. The guides on the support frame are formed by curved U-rails in this seat. In these U-rails, which are arranged on both sides of the seat, two rollers attached to each side of the seat engage. One roller is located at the back of the seat. One roller is located approximately in the middle of the seat. The backrest and the actual seat are firmly connected to one another. If the seat moves forward relative to its support frame, it tilts backwards, with the backrest also tilting and, as a result, protrudes further back than in the normal position. This means that this seat cannot be used, for example, as a rear seat in a motor vehicle, where there is usually no room for the backrest to tilt backwards. The roller U-rail guide of this seat also has the disadvantage that the seat cannot be easily lifted off the support frame, which is necessary when cleaning the inside of the vehicle. The rollers can also jam in their guides under certain circumstances, namely if the seat is tilted relative to the support frame. Since the front rollers are arranged approximately in the middle area of the seat and practically have to be arranged if the guide rails are not to be extended far beyond the front edges of the seat, the focus of the seat and the person must also be ensured so that a safe operation is guaranteed , lie relatively far back, which is probably the reason that the backrest and the actual seat are attached to one another.

Der Erfindung liegt die Aufgabe zugrunde, die neben dem Fahrer und auf den rückwärtigen Sitzen sitzenden Fahrgäste in den verhältnismäßig häufigen Fällen, in denen plötzlich bei einer unteren oder einer mittleren Geschwindigkeit stark gebremst werden muß, davor zu bewahren, nach vom geschleudert zu werden.The invention is based on the object, in addition to the driver and Passengers sitting on the rear seats in the relatively frequent ones Cases where suddenly at a lower or a medium speed must be braked strongly to prevent being thrown forward.

Der erfindungsgemäße Sitz ist dadurch gekennzeichnet, daß die Lehne unabhängig vom eigentlichen Sitz am Tragrahmen gehalten ist und die vordere Schrägfläche aus einer von der Vorderkante des Sitzes nach rückwärts unten verlaufenden Führung besteht, die auf dem Tagrahmen aufliegt. Die Trennung von Lehne und eigentlichem Sitz ist an sich bekannt, jedoch bei einer Vorrichtung, bei der der eigentliche Sitz durch eine äußere Kraft, nicht aber durch die Massenkraft von Sitz und Person (selbst), gekippt wird.The seat according to the invention is characterized in that the back is held independently of the actual seat on the support frame and the front inclined surface from a guide running backwards and downwards from the front edge of the seat exists, which rests on the tag frame. The separation of the backrest and the real thing Seat is known per se, but in a device in which the actual Sitting by an external force, but not by the inertia of the seat and the person (itself), is tilted.

Ein erfindungsgemäßer Sitz liegt lose auf dem Tragrahmen auf, kann also leicht etwa zum Reinigen des Fahrzeuginnern abgenommen werden. Verklemmen kann er sich praktisch nicht, denn er kann sich etwas schräg gegenüber der Mittellinie des Tragrahmens relativ zum Tragrahmen verschieben lassen. Hinzu kommt, daß vorhandene Sitze und Tragrahmen leicht im Sinn der Erfindung umgebaut werden können. Schließlich dürfte ein erfindungsgemäßer Sitz sich auch dann sicher unter der Wirkung der Massenkraft im gewünschten Sinn verschieben, wenn der Schwerpunkt von Sitz und Person nicht so weit hinten liegt wie bei dem vorbekannten, oben beschriebenen Sitz: Er wird nämlich stets im Bereich der Vorderkante des Tragrahmens abgestützt.A seat according to the invention rests loosely on the support frame so they can easily be removed for cleaning the interior of the vehicle, for example. Can jam he is practically not, because he can be a little diagonally opposite the center line the support frame can be moved relative to the support frame. In addition, there is that existing Seats and support frames can be easily converted in accordance with the invention. In the end A seat according to the invention should then also be safe under the action of the inertia force Move in the desired direction if the focus of the seat and person is not is as far back as in the previously known seat described above: it will namely always supported in the area of the front edge of the support frame.

In Ausbildung der Erfindung weist der Sitz eine an sich bekannte - bei Verzögerung des Fahrzeugs unter der Massenkraft ansprechende Sperre zur Verriegelung der Rückenlehne auf. Die Sperre kann aus einem Pendelhaken bestehen, der beim Ausschwingen in eine Halterung des Tragrahmens einrastet. Die Figuren zeigen ein Ausführungsbeispiel, und zwar F i g. 1 einen Sitz in Normalstellung; F i g. 2 denselben Sitz nach Verschiebung in die das Vorschleudem der Person hindernde Schräglage. Der Rahmen 1 des Sitzpolsters 2 liegt normalerweise lose auf dem Tragrahmen 3. Der Rahmen 1 ist - 1--1. vorderseitig mit zwei von vorn nach hinten schräg nach unten verlaufenden Gleitschienen4 versehen. Entsprechende, jedoch von vorn nach hinten ansteigende Gleitschienen 5 befinden sich an der Rückseite des Tragrahmens 3. In embodiment of the invention, the seat comprises a per se known - in an engaging lock when deceleration of the vehicle under the inertial force to lock the backrest. The lock can consist of a pendulum hook that snaps into a holder of the support frame when it swings out. The figures show an exemplary embodiment, namely FIG. 1 a seat in the normal position; F i g. 2 the same seat after being moved into the inclined position preventing the person from being thrown forward. The frame 1 of the seat cushion 2 normally lies loosely on the support frame 3. The frame 1 is - 1--1. Provided on the front with two slide rails4 running downwards at an angle from front to back. Corresponding slide rails 5 that rise from the front to the rear are located on the rear side of the support frame 3.

Bei starkem Bremsen oder einer ähnlichen Verzögerung verläßt der Sitz 1, 2 unter der Einwirkung der Massenkraft, die auf ihn und auf die auf ihm sitzende Person einwirkt, die Stellung nach Fig. 1 derart. daß die Sitzvorderkante auf Grund der am Sitz 1, 2 befestigten Gleitschienen 4, die über die Vorderkante des Tragrahmens3 gleiten, nach oben steigt, während das rückwärtige Ende des Sitzes 1, 2 auf den schräg nach unten gerichteten Gleitschienen 5 nach unten gleitet und dabei das Hochsteigen der vorderen Kante des Sitze 1, 2 unterstützt. An die nach vorn kippbare, vom Sitz 1, 2 getrennte Rücklehne 6 ist ein als Pendelgewicht wirksamer Fanghaken 7 angelenkt, der im Fall eines starken Bremsens nach vorn schwingt und einen Gegenhaken 8 am Tragrahmen 3 hintergreift, so daß die Lehne 6 gegen Verschwenken nach vorn verriegelt wird. Der Fanghaken 7 ist so angeordnet, daß er bei normalem langsamem Vorkippen der Rückenlehne 6 am Gegenhaken 8 vorbeigeht.In the event of heavy braking or a similar delay, the seat 1, 2 leaves the position according to FIG. 1 under the action of the inertia force which acts on it and on the person sitting on it. that the front edge of the seat due to the slide rails 4 attached to the seat 1, 2, which slide over the front edge of the support frame 3, rises upwards, while the rear end of the seat 1, 2 slides downwards on the obliquely downward slide rails 5 and thereby the Rising up the front edge of the seats 1, 2 supports. On the forward tiltable backrest 6, which is separate from the seat 1, 2, an effective pendulum weight catch hook 7 is articulated, which swings forward in the event of heavy braking and engages behind a counter hook 8 on the support frame 3 so that the backrest 6 prevents it from pivoting forward is locked. The catch hook 7 is arranged in such a way that it passes the counter hook 8 when the backrest 6 is slowly tilted forward normally.
