Abstract

The invention relates to a motor-vehicle seat with an approximately U-shaped hoop which is assigned to the seat cushion, the free leg ends of which hoop are mounted on the seat frame such that they can be moved in a pivoting manner about a pivoting axis lying at the rear and the web of which hoop, which connects the two legs and determines the inclination of the seat-user's thighs, bears in a supporting manner near to the front side of the seat cushion and on the lower side thereof, the supporting effect being brought about by at least one device which can lock the hoop relative to the seat frame. In a motor-vehicle seat of this type, an effective spacing safeguard is provided by virtue of the fact that in normal driving mode the hoop follows the spring movements of the seat cushion and the lockable device is only transferred into its operative position by a weight, which is suspended in a swinging manner and can be deflected counter to the force of a spring, when a predetermined vehicle deceleration is exceeded.

Description

Die Erfindung betrifft einen Kraftwagensitz mit einem dem Sitzkissen zugeordneten, etwa U-förmigen Bügel, dessen freie Schenkelenden um eine hinten liegende Schwenkachse schwenkbeweglich am Sitzrahmen gelagert sind und dessen beide Schenkel verbindender Steg, den Anstellwinkel der Oberschenkel des Sitzbenutzers bestimmend, nahe der Vor­ derseite des Sitzkissens und unterseitig desselben ab­ stützend anliegt, wobei die Abstützung durch mindestens eine, den Bügel gegenüber dem Sitzrahmen blockierbare Einrichtung herbeigeführt wird.The invention relates to a motor vehicle seat with a Seat cushion associated, approximately U-shaped bracket, the free leg ends around a rear pivot axis are pivotally mounted on the seat frame and its web connecting both legs, the angle of attack of Determining the thigh of the seat user, near the front the side of the seat cushion and the underside of the same is supportive, the support by at least one that locks the bracket to the seat frame Establishment is brought about.

Ein derartiger Kraftwagensitz, bei dem die blockierbare Einrichtung als Neigungsverstelleinrichtung ausgebildet ist, kann der DE-OS 36 24 398 als bekannt entnommen wer­ den. Bei einem Frontalaufprall verhindert der Bügel wohl ein zu starkes Einsitzen des Sitzbenutzers und wirkt dabei als Abstandssicherung, jedoch ist im normalen Fahrbetrieb, insbesondere bei schwächerer Polsterauflage und einsei­ tigem Einfedern der Sitzkomfort stark beeinträchtig, da der harte Bügel durch das Polster hindurch wahrzunehmen ist.Such a motor vehicle seat, in which the lockable Device designed as a tilt adjustment device is, the DE-OS 36 24 398 known as known the. In the event of a head-on collision, the bracket prevents it excessive sitting by the seat user and works as a distance safeguard, but in normal driving, especially with weaker upholstery and one egg cushioning severely affects seating comfort because  perceive the hard temple through the upholstery is.

Aufgabe der Erfindung ist es, eine Abstandssicherung zu schaffen, die im normalen Fahrbetrieb selbst bei einsei­ tigem Einfedern als angenehm empfunden wird, die jedoch bei einem Aufprall des Fahrzeugs mit äußerst geringer zeitlicher Verzögerung wirksam wird, ohne daß hierzu eine Relativverschiebebewegung von Sitzteilen zueinander not­ wendig ist.The object of the invention is to secure a distance create that in normal driving even at einsei compression is perceived as pleasant, however in the event of an impact of the vehicle with extremely low time delay takes effect without this Relative displacement movement of seat parts to each other not is agile.

Diese Aufgabe wird bei einem Kraftwagensitz der im Ober­ begriff des Anspruches 1 angegebenen Gattung erfindungsgemäß durch die Merkmale im Kennzeichenteil des Anspruches 1 gelöst.This task is carried out in a car seat in the upper Concept of claim 1 specified genus according to the invention by the features in the characterizing part of the Claim 1 solved.

Durch die DE-OS 28 43 669 ist zwar bereits eine Abstands­ sicherung bekannt, die den Federungsbewegungen des Sitz­ kissens im normalen Fahrbetrieb keinen Widerstand entge­ gensetzt und die erst im Aufprallfall wirksam werden soll, jedoch bedarf es zur Arretierung der Sicherung einer Verschiebebewegung des Federkerns und der Polsterauflage in Fahrtrichtung nach vorn. Eine derartige Verschiebebewegung ist nicht in jedem Fall gegeben oder setzt erst mit zeitlicher Verzögerung ein, insbesondere wenn man bedenkt, daß bei einem Frontalaufprall durch das Aktivieren eines Gurtraffers zum Aufprallzeitpunkt eine nach vorn gerichtete Verschiebung des Federkerns und der Polsterauflage verhindert wird. DE-OS 28 43 669 is already a distance fuse known, the suspension movements of the seat kissens no resistance during normal driving set and which should only take effect in the event of an impact, however, one is required to lock the fuse Sliding movement of the spring core and the cushion pad in the direction of travel forward. Such one Movement is not always given or only starts with a delay, in particular if you consider that in a frontal impact by the Activate a belt retractor at the time of impact forward displacement of the innerspring and the Upholstery is prevented.  

Bei einem bevorzugten Ausführungsbeispiel der Erfindung weist die blockierbare Einrichtung eine vertikal geführte Zahnstange und die auslenkbare Masse mindestens einen Zahn auf, der bei ausgelenkter Masse in eine zugeordnete Zahn­ lücke der Zahnstange eingreift.In a preferred embodiment of the invention the blockable device has a vertically guided Rack and the deflectable mass at least one tooth on, with the deflected mass in an assigned tooth gap of the rack engages.

Es ist aber auch möglich, die blockierbare Einrichtung mit einer vertikal geführten Stange zu versehen und die aus­ lenkbare Masse in ihrer ausgelenkten, durch eine Federrast gesicherten Stellung als Anlaufkeil für die abwärts stre­ bende Stange auszubilden.But it is also possible to use the blockable device to provide a vertically guided rod and the steerable mass in its deflected, by a spring catch secured position as a starting wedge for the downstairs stre training rod.

Der Gegenstand der Erfindung wird nachfolgend anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Er zeigt:The object of the invention is described below with reference to two embodiments shown in the drawing explained in more detail. He shows:

Fig. 1 eine Sitzanordnung mit einer ersten, als Zahnrast ausgebildeten blockierbaren Ein­ richtung und Fig. 1 shows a seat assembly with a first, designed as a tooth lock blockable A direction

Fig. 2 in größerem Maßstab eine zweite, die Funk­ tion eines Anlaufkeils übernehmende bloc­ kierbare Einrichtung. Fig. 2 on a larger scale a second, the func tion taking over a starting wedge bloc kbare device.

Ein in Fig. 1 vereinfacht dargestellter Kraftwagensitz 1 besteht aus einer Rückenlehne 2 und einem auf einem Un­ tergestell 3 ruhenden Sitzkissen 4. Von einem randseitig den Sitzbezug 5 aufnehmenden Sitzrahmen 6 streben einen nicht näher gezeigten Federkern bildende Federn nach oben, von denen der Einfachheit halber nur zwei Schraubendruck­ federn 7 angedeutet sind. Die Federn stützen sich ober­ seitig an einem Rahmen 8 ab, an dem nahe der Vorderseite 9 des Sitzkissens 4 auch ein die beiden Schenkel 10 eines U-förmigen Bügels 11 verbindender Steg 12 anliegt. Der Bügel 11 ist um eine sitzrahmenseitige Schwenkachse 13 schwenkbeweglich gelagert, wobei durch eine Schenkelfeder 14 stets eine leichte Anlage des Bügels 12 unterseitig des Sitzkissens 4 erfolgt.A simplified form in Fig. 1 illustrated motor vehicle seat 1 comprises a backrest 2 and a stationary on a Un tergestell 3 seat pad 4. From an edge of the seat cover 5 receiving seat frame 6 strive to form a spring core, not shown, springs, of which, for the sake of simplicity, only two helical compression springs 7 are indicated. The springs are supported on the upper side on a frame 8 , on which a web 12 connecting the two legs 10 of a U-shaped bracket 11 also abuts near the front 9 of the seat cushion 4 . The bracket 11 is pivotally mounted to a seat frame-side pivot axis 13, which always takes place on the underside 12 by a leg spring 14 a slight conditioning of the bracket of the seat cushion. 4

Dem Bügel 11 zugeordnet ist eine blockierbare Einrichtung 15, die erst wirksam wird, wenn eine vorbestimmte Fahr­ zeugverzögerung eintritt und die nur dann den Bügel 11 in seiner jeweiligen Lage festlegt, während im normalen Fahrbetrieb der Bügel 11 den Federbewegungen des Sitzkis­ sens 4 ungehindert folgen kann.The bracket 11 is assigned a blockable device 15 , which takes effect only when a predetermined driving tool delay occurs and which only then defines the bracket 11 in its respective position, while in normal driving operation of the bracket 11 the spring movements of the Sitzkis sens 4 can follow unhindered .

Gemäß Fig. 1 besteht die blockierbare Einrichtung 15 aus einer in Höhenrichtung geführten und in ein Langloch 16 im Schenkel 10 eingreifenden Zahnstange 17. Dieser ist eine gegen die Kraft einer Feder 18 beim Erreichen einer vor­ bestimmten Fahrzeugverzögerung in Pfeilrichtung auslenk­ bare Masse 19 mit einem Zahn 20 zugeordnet, der bei aus­ gelenkter Masse 19 in eine zugekehrte Zahnlücke 21 der Zahnstange 17 eingreift, wobei ein ortsfester Anschlag 22 die Auslenkbewegung der Masse 19 begrenzt.Referring to FIG. 1, the lockable device 15 from a guided in the height direction and in a slot 16 in the leg 10 engaging rack 17. This is a against the force of a spring 18 when reaching a certain vehicle deceleration in the direction of the arrow bare mass 19 associated with a tooth 20 , which engages in a tooth gap 21 of the toothed rack 17 from steered mass 19 , with a fixed stop 22 the deflection movement the mass 19 limited.

Tritt unfallbedingt ein Eingriff des Zahnes 20 in die zu­ geordnete Zahnlücke 21 der Zahnstange 17 ein, so erfolgt über diese ein kraftschlüssiges Abstützen des Bügels 11 ein, der nun als Abstandssicherung für die Oberschenkel des Sitzbenutzers wirkt. Dadurch wird während des Unfall­ ablaufes zuverlässig verhindert, daß der Insasse in das Sitzkissen hineingedrückt wird, wobei der Beckengurt nach oben rutscht und wegen des nun ungünstigen Gurtverlaufes schwere innere Verletzungen hervorrufen kann.If, due to an accident, the tooth 20 engages in the tooth gap 21 of the toothed rack 17 that is assigned to it, then a force-fit support of the bracket 11 takes place, which now acts as a spacer for the thighs of the seat user. This reliably prevents the occupant from being pressed into the seat cushion during the course of the accident, the lap belt slipping upwards and, due to the now unfavorable course of the belt, being able to cause serious internal injuries.

Wie Fig. 2 zeigt, kann der Bügel 11 auch dadurch an einer Abwärtsbewegung gehindert werden, daß in das Langloch 16 im Schenkel 10 eine in Höhenrichtung geführte Stange 23 eingreift, die bei einem Frontalaufprall gegen die einen Anlaufkeil bildende ausgelenkte Masse 19 anläuft. Damit die Masse 19 in ihrer Auslenklage sicher gehalten wird, ist eine Federrast 24 vorgesehen, die aus ortsfesten Rasten 25 und einer Feder 26 besteht, die je nach Aus­ lenkweite der Masse 19 in eine der Rasten 25 eingreift.As shown in Fig. 2, the bracket 11 can also be prevented from moving downward by engaging a rod 23 guided in the vertical direction in the elongated hole 16 in the leg 10 , which rod 23 runs against the deflected mass 19 forming a starting wedge in a frontal impact. So that the mass 19 is held securely in its deflection position, a spring catch 24 is provided, which consists of fixed detents 25 and a spring 26 which, depending on the steering distance from the mass 19, engages in one of the detents 25 .
