Die Erfindung betrifft eine Sicherheitsvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1 sowie ein Verfahren zum Ansteuern einer solchen Sicherheitsvorrichtung.The invention relates to a safety device with the features of the preamble of claim 1 and a method for driving such a safety device.

Sitzpolster gebildet wird. Die Sicherheitsvorrichtung umfasst weiterhin ein der Sitzfläche zugeordnetes Sicherungselement und eine mit dem Sicherungselement inSeat pad is formed. The safety device further comprises a securing element associated with the seat surface and one with the securing element in

Dieser Effekt wird in Fachkreisen englischsprachig auch als "submarining" bezeichnet.Forward displacement in the direction of travel under the seat belt, especially the lap belt, submerges. This effect is referred to in English as "submarining".
Die Sitzfläche bildet dabei einen Bestandteil des Kraftfahrzeugsitzes, dem die Sicherheitsvorrichtung zugeordnet ist. Sie bildet jedoch gleichzeitig auch einen Bestandteil der Sicherheitsvorrichtung selbst, da sie gemeinsam mit dem Sicherungselement die Vorverlagerung des Beckens einer auf der Sitzfläche sitzenden Person begrenzen soll. Hierzu wird das Sicherungselement mittels der Verstelleinrichtung näher an die Sitzfläche (des Sitzpolsters) herangeführt, wobei es gegebenenfalls auch zu einer gewissen Deformation der Sitzfläche kommen kann. Allerdings wird hierbei nicht die räumliche Lage der Sitzfläche als Ganzes (etwa durch Verschwenken der Sitzfläche) verändert.The seat forms a part of the vehicle seat, which is associated with the safety device. However, at the same time, it also forms part of the safety device itself, since together with the securing element it is intended to limit the forward displacement of the pelvis of a person sitting on the seat. For this purpose, the securing element is brought closer by means of the adjusting device to the seat surface (of the seat cushion), wherein it possibly also lead to a certain deformation of the seat. However, this does not change the spatial position of the seat as a whole (for example, by pivoting the seat).
Eine solche Sicherheitsvorrichtung ist aus dem Dokument WO 2004/007237 bekannt. Im Crash-Fall bzw. beim Auslösen eines PreCrash-Warnsystems wird die Sitzfläche des Kraftfahrzeugsitzes durch die Verstellung des Sicherungselements versteift, um ein Herausrutschen einer auf dem Fahrzeugsitz befindlichen Person unter dem Sicherheitsgurt hindurch zu verhindern. Nach dem Unfall kann das Sicherungselement wieder in seine Ruhelage zurückgestellt werden.Such a security device is known from document WO 2004/007237. In the event of a crash or when triggering a PreCrash warning system, the seat of the motor vehicle seat is stiffened by the adjustment of the securing element to prevent slipping out of a person located on the vehicle seat under the seat belt. After the accident, the fuse element can be returned to its rest position.
Der Erfindung liegt die Aufgabe zugrunde, die Einsatzmöglichkeiten der eingangs beschriebenen Sicherheitsvorrichtung zu vermehren.The invention has the object to multiply the possible uses of the safety device described above.
Die Aufgabe wird von einer Sicherheitsvorrichtung mit den Kennzeichen des Anspruchs 1 gelöst. Die Verstelleinrichtung ist dadurch nicht mehr darauf beschränkt, das Sicherungselement zwischen einer Ruheposition und einer Sicherungsposition zu verstellen, sondern kann über die Verstelleinrichtung auch in eine oder mehrere Zwischenpositionen verstellt werden, was eine nützliche Zusatzfunktion bereitstellt. Dadurch kann z.B. ein manuelles Verstellen der Sitzhärte ermöglicht werden.The object is achieved by a safety device with the characteristics of claim 1. The adjusting device is thereby no longer limited to adjust the securing element between a rest position and a securing position, but can also be adjusted via the adjusting device in one or more intermediate positions, which provides a useful additional function. Thereby, e.g. a manual adjustment of the seat hardness are enabled.
Unter der Ruheposition wird dabei die unterste Stellung des Sicherungselements verstanden, also die Position des Sicherungselements, die von der Sicherungsposition am weitesten entfernt ist. In der Sicherungsposition befindet sich das Sicherungselement in seiner obersten Stellung. Sicherungsposition und Ruheposition bilden die Umkehrpunkte der maximalen Verstellbahn des Sicherungselements. Das Sicherungselement kann also durch die Verstelleinrichtung in eine Position bzw. Lage relativ zur Sitzfläche gestellt werden, die entweder der Sicherungsposition, der Ruheposition oder mindestens einer Zwischenposition dazwischen entspricht.Under the rest position is understood to be the lowest position of the securing element, ie the position of the securing element which is furthest away from the securing position. In the securing position, the securing element is in its uppermost position. Safety position and rest position form the reversal points of the maximum displacement of the fuse element. The securing element can thus be set by the adjusting device in a position or position relative to the seat, which corresponds to either the securing position, the rest position or at least one intermediate position therebetween.
Bevorzugt ist das Sicherungselement durch die Verstelleinrichtung in mehrere Zwischenpositionen zwischen der Ruheposition und der Sicherungsposition verstellbar. Insbesondere kann die Verstelleinrichtung zum im Wesentlichen stufenlosen Verstellen des Sicherungselements zwischen der Ruheposition und der Sicherungsposition dienen. Die Positionierungsmöglichkeiten des Sicherungselements werden dadurch erhöht. Bei einer Ausführungsform ist durch Einstellen der Position des Sicherungselements die Sitzhärte der Sitzfläche einstellbar. Dabei kann ein Regelungs- oder Bedienelement vorgesehen sein, mittels dem die Sitzhärte z.B. manuell einstellbar ist. Durch Verschieben bzw. Einstellen einer mittels des Sicherungselementes erzeugbaren Sitzrampe kann ein Sitzschaum des Kraftfahrzeugsitzes unterschiedlich komprimiert werden und somit die Sitzhärte unterschiedlich eingestellt werden. Dies bietet einen individuell einstellbaren und dadurch erhöhten Sitzkomfort für den Fahrzeuginsassen.Preferably, the securing element is adjustable by the adjusting device in a plurality of intermediate positions between the rest position and the securing position. In particular, the adjusting device can serve for the substantially continuous adjustment of the securing element between the rest position and the securing position. The positioning possibilities of the security element are thereby increased. In one embodiment, by adjusting the position of the securing element, the seat hardness of the seating surface is adjustable. In this case, a control or operating element can be provided by means of which the seat hardness, for example, is manually adjustable. By displacing or adjusting a seat ramp which can be generated by means of the securing element, a seat foam of the motor vehicle seat can be compressed differently and thus the seat hardness can be adjusted differently. This offers individually adjustable and thus increased seating comfort for the vehicle occupants.
Die Verstelleinrichtung ist bevorzugt so ausgebildet, dass sie durch automatisches Einstellen der Position des Sicherungselements relativ zur Sitzfläche die Sitzhärte derThe adjusting device is preferably designed so that it by adjusting the position of the securing element relative to the seat surface, the seat hardness of
Sitzfläche an eine Geschwindigkeit des Kraftfahrzeuges anpasst, in der sich derFit seat to a speed of the motor vehicle, in which the
Kraftfahrzeugsitz mit der Sicherheitsvorrichtung befindet. Diese Sitzhärtenanpassung kann z.B. mittels Sensoren wie z. B. Querbschleunigungssensoren des Fahrzeuges adaptiv zum Fahrstil erfolgen, um so z.B. einen besseren Halt des Fahrers bei einem „sportlichen" Fahrstil zu ermöglichen.Motor vehicle seat is located with the safety device. This seat hardness adjustment may e.g. by means of sensors such. B. lateral acceleration sensors of the vehicle are adaptive to the driving style, so as to e.g. to allow a better grip of the driver in a "sporty" driving style.
Die Sicherheitsvorrichtung weist bevorzugt mindestens einen Verstellmotor auf, mittels dem die Verstelleinrichtung das Sicherungselement bewegt. Durch eine Bewegung des Sicherungselements relativ zur Sitzfläche, insbesondere durch Kompression des Sitzschaumes, wird auf die Sitzfläche eingewirkt, ohne notwendigerweise deren Lage zu verändern.The safety device preferably has at least one adjusting motor, by means of which the adjusting device moves the securing element. By a movement of the securing element relative to the seat, in particular by compression of the seat foam, is acted upon the seat, without necessarily changing their position.
In einer besonders bevorzugten Ausführungsform der Sicherheitsvorrichtung ist die Verstelleinrichtung als automatische Verstelleinrichtung ausgebildet, die mit Sensoren zum Detektieren des Fahrverhaltens eines Kraftfahrzeuges kommuniziert, in dem die Sicherungsvorrichtung für einen Kraftfahrzeugsitz des Kraftfahrzeuges eingebaut ist. Die Sensoren senden ein Signal aus, wenn sie eine Gefahrensituation, insbesondere eine Crash-Situation detektieren. Auf dieses Signal hin verstellt die Verstelleinrichtung automatisch das Sicherungselement in die Sicherungsposition, um so durch das Erzeugen einer (geneigten, insbesondere zum vorderen Sitzende hin ansteigenden) Sitzrampe ein Durchrutschen einer Person unter einem Sicherheitsgurt („submarining") zu verhindern. Das Verstellen des Sicherungselements erfolgt dabei nicht nur aus der Ruheposition heraus, sondern auch wenn es zuvor in einer Zwischenposition eingestellt war. In einer Weiterbildung dieser Ausführungsform weist die Verstelleinrichtung mindestens eine Vibrationsfunktion auf, in der die Verstelleinrichtung das Sicherungselement zwischen mindestens zwei unterschiedlichen Positionen relativ zur Sitzfläche in einer Vibrationsbewegung hin- und herbewegt. Dies geschieht auf ein Signal der Detektoren hin, und dient zur Warnung vor einer Gefahrensituation als haptisches Warnsignal über die Sitzfläche. Die oszillierende Vibrationsbewegung erlaubt eine haptische und gutfühlbare Warnung im Beckenbereich. In Kombination mit ACC (Active Cruise Control) oder PreCrash Sensorik kann diese Option zur Warnung des Fahrers ausgenutzt werden.In a particularly preferred embodiment of the safety device, the adjusting device is designed as an automatic adjusting device which communicates with sensors for detecting the driving behavior of a motor vehicle in which the safety device for a motor vehicle seat of the motor vehicle is installed. The sensors emit a signal if they detect a dangerous situation, in particular a crash situation. In response to this signal, the adjusting device automatically adjusts the securing element into the securing position so as to prevent a person from slipping underneath a safety belt ("submarining") by generating a (inclined, in particular rising towards the front seat) seat ramp takes place not only from the rest position, but also if it was previously set in an intermediate position. In a development of this embodiment, the adjusting device has at least one vibration function, in which the adjusting device moves the securing element back and forth between at least two different positions relative to the seat surface in a vibrating motion. This is done in response to a signal from the detectors, and serves as a warning of a dangerous situation as a haptic warning signal on the seat. The oscillating vibration movement allows a haptic and good feeling warning in the pelvic area. Combined with ACC (Active Cruise Control) or PreCrash sensors, this option can be used to alert the driver.
Bevorzugt erfolgt dabei die Vibrationsbewegung des Sicherungselements um die aktuell eingestellte Position des Sicherungselements herum. Ist das Sicherungselement in einer Zwischenposition eingestellt, so können die Umkehrpunkte der Vibrationsbewegung zwei weitere Zwischenpositionen sein, von denen die eine näher an der Ruheposition und die andere näher an der Sicherungsposition liegt als die eingestellte Zwischenposition. Alternativ dazu kann die Vibrationsbewegung auch zwischen der eingestellten Zwischenposition und einer anderen Position als Umkehrpunkte der Vibrationsbewegung erfolgen, also z.B. zwischen der eingestellten Zwischenposition einerseits und der Sicherungsposition, der Ruheposition oder einer weiteren Zwischen position andererseits. Dabei wäre auch eine Vibrationsbewegυng zwischen der Ruheposition und der Sicherungsposition möglich, was aber abhängig von deren Abstand zueinander aufgrund der extremen Hubhöhe einen schlechteren Komfort für die auf dem Kraftfahrzeugsitz sitzende Person zur Folge hätte.The vibration movement of the securing element preferably takes place around the currently set position of the securing element. If the securing element is set in an intermediate position, the points of reversal of the vibrating movement can be two further intermediate positions, one of which is closer to the rest position and the other closer to the securing position than the set intermediate position. Alternatively, the vibratory motion may also occur between the adjusted intermediate position and another position as reversal points of the vibratory motion, e.g. between the set intermediate position on the one hand and the securing position, the rest position or another intermediate position on the other. In this case, a Vibrationsbewegυng between the rest position and the securing position would be possible, but depending on their distance from each other due to the extreme lifting height would have a worse comfort for the person sitting on the vehicle seat person result.
In einer Weiterentwicklung dieser Ausführungsform weist die Verstelleinrichtung mehrere Vibrationsfunktionen auf, in denen die Verstelleinrichtung in Abhängigkeit der von den Sensoren zum Detektieren des Fahrverhaltens des Kraftfahrzeuges detektierten Gefahrensituation unterschiedliche Teile des Sicherungselements zwischen mindestens zwei unterschiedlichen Positionen relativ zur Sitzfläche in einer Vibrationsbewegung hin- und herbewegt. So kann der Fahrer anhand der ausgeführten Vibrationsbewegung zwischen unterschiedlichen, von den Sensoren detektierten Gefahrensituationen wie z.B. dem Abkommen von der Fahrbahn, dem Unterschreiten eines Sicherheitsabstandes zu einer bestimmten Fahrzeugseite hin oder dem Überschreiten der zulässigen Höchstgeschwindigkeit unterscheiden. Dabei sind durch die Verstelleinrichtung bevorzugt eine rechte Seite und eine linke Seite des Sicherungselements separat zwischen mindestens zwei Positionen relativ zur Sitzfläche in einer Vibrationsbewegung hin- und herbewegbar. Das separate Ansteuern eines linken oder rechten Teils des Sicherungselements ist besonders dazu geeignet, den Fahrer vor dem Abkommen von der Fahrbahn in der entsprechenden Fahrzeugrichtung bzw. dem Unterschreiten eines Sicherheitsabstandes in dieser Richtung zu warnen.In a further development of this embodiment, the adjusting device has a plurality of vibration functions, in which the adjusting device reciprocates different parts of the securing element between at least two different positions relative to the seat surface in a vibrating motion as a function of the danger situation detected by the sensors for detecting the driving behavior of the motor vehicle. Thus, based on the executed vibration movement, the driver can differentiate between different dangerous situations detected by the sensors, such as the agreement from the roadway, the falling below a safety distance to a specific vehicle side or exceeding the permissible maximum speed. In this case, by the adjustment preferably a right side and a left side of the securing element back and forth separately between at least two positions relative to the seat in a vibrating motion and forth. The separate driving of a left or right-hand part of the securing element is particularly suitable for warning the driver of the lane departure in the corresponding vehicle direction or falling below a safety distance in this direction.
Bevorzugt weist die Verstelleinrichtung mindestens zwei Verstellmotoren auf, nämlich einen, der einer rechten Seite des Sicherungselements zugeordnet ist, und einen, der dessen linker Seite zugeordnet ist. Mittels der Verstellmotoren ist die rechte Seite und die linke Seite des Sicherungselements separat in mindestens eine sich zwischen der Sicherungsposition und der Ruheposition befindliche Zwischenposition verstellbar sowie ansteuerbar.Preferably, the adjusting device has at least two adjusting motors, namely one associated with a right side of the securing element and one associated with the left side thereof. By means of the adjusting motors, the right side and the left side of the securing element is separately adjustable and controllable in at least one intermediate position located between the securing position and the rest position.
Gemäß einer bevorzugten Weiterbildung der Erfindung ist die zur Betätigung des Sicherungselementes vorgesehene Verstelleinrichtung gekoppelt mit Mitteln zur Aktivierung eines motorisierten Sicherheitsgurtsystems des entsprechenden Kraftfahrzeugsitzes. Hiermit kann in kritischen Fahrsituationen, in Ergänzung und parallel zu den vorbeschriebenen Funktionen des Sicherungselementes, eine automatische Straffung des Sicherheitsgurtes hervorgerufen werden, das (insbesondere in einer Pre- Crash-Phase) dem entsprechenden Fahrzeuginsassen zusätzlichen Halt vermittelt. Hierdurch kann dem Fahrzeuginsassen insbesondere auch ein Gefühl der Unterstützung in kritischen Fahrsituationen, wie z. B. Schleudersituationen, vermittelt werden.According to a preferred development of the invention, the adjusting device provided for actuating the securing element is coupled with means for activating a motorized safety belt system of the corresponding motor vehicle seat. This can be caused in critical driving situations, in addition to and parallel to the above-described functions of the security element, an automatic tightening of the seat belt, which (especially in a pre-crash phase) provides the appropriate vehicle occupant additional support. In this way, the vehicle occupant in particular a sense of support in critical driving situations, such. B. Schleudersituationen be taught.
In einer Ausführungsform ist das Sicherungselement unterhalb einer Polsterung der Sitzfläche, insbesondere im Kraftfahrzeugsitz selber, angeordnet und wird in einem Crash-Fall mittels der Verstelleinrichtung näher an die Sitzfläche herangeführt. Insbesondere lässt sich das Sicherungselement dabei auf einer Sitzschale des Sitzteils anordnen. Dadurch kann das Sicherungselement bei einem Crash-Fall auf einfache Weise in Richtung der Sitzfläche bewegt werden, so dass Sitzfläche und Sicherungselement eine im Wesentlichen entlang der Erstreckungsrichtung des Sicherungselements wirksame Schwelle bilden, die dem Vorverlagern des Beckens einer auf dem Kraftfahrzeugsitz sitzenden Person entlang der gesamten Breite des Kraftfahrzeugsitzes entgegenwirken. Vorteilhaft ist das Sicherungselement als Rampe ausgebildet, die so angeordnet ist, dass sie auf die Sitzfläche bzw. auf dessen Polsterung durch Druck einwirkt.In one embodiment, the securing element is below a padding of the seat, in particular in the motor vehicle seat itself, arranged and is brought closer in a crash case by means of the adjustment closer to the seat. In particular, the securing element can be arranged on a seat shell of the seat part. As a result, the securing element can be moved in the event of a crash in a simple manner in the direction of the seat, so that seat and securing element form a substantially effective along the extension direction of the securing element threshold, the Vorverlagern the pelvis of a person sitting on the vehicle seat person along the entire Counteract the width of the vehicle seat. Advantageously, the securing element is designed as a ramp, which is arranged so that it acts on the seat or on its padding by pressure.
Das Sicherungselement weist hierzu bevorzugt einen Verstellabschnitt auf, der bei der Zustellbewegung des Sicherungselements in eine solche Position gebracht wird, dass er (zusammen mit der Sitzfläche) die Vorverlagerung des Beckens einer auf der entsprechenden Sitzfläche sitzenden Person begrenzt.For this purpose, the securing element preferably has an adjustment section which is brought into such a position during the advancing movement of the securing element that it limits (together with the seating surface) the forward displacement of the pelvis of a person sitting on the corresponding seat.
Ferner weist das Sicherungselement mindestens einen Abschnitt, z.B. in Form eines Endabschnitts, auf, über den das Sicherungselement entlang seiner Bewegungsrichtung geführt ist und an dem gegebenenfalls auch eine Antriebseinrichtung angreifen kann.Furthermore, the securing element has at least one section, e.g. in the form of an end portion, on, over which the securing element is guided along its direction of movement and on which optionally also a drive device can act.
Die Zustellbewegung des Sicherungselements in einem Crash-Fall kann als Translation, als Rotation oder als eine Kombination einer Translation mit einer Rotation ausgebildet sein. Alle drei Varianten einer Zustellbewegung haben gemeinsam, dass sich das Sicherungselement in Richtung des Beckens der auf der Sitzfläche des Kraftfahrzeugsitzes sitzenden Person bewegt.The feed movement of the securing element in a crash case can be designed as a translation, as a rotation or as a combination of a translation with a rotation. All three variants of a feed movement have in common that the securing element moves in the direction of the pelvis of the person sitting on the seat of the motor vehicle seat.
Die erfindungsgemäße Aufgabe wird weiterhin durch ein Verfahren nach Anspruch 21 zum Ansteuern einer erfindungsgemäßen Sicherheitsvorrichtung gelöst, die einem Kraftfahrzeugsitz eines Kraftfahrzeuges zugeordnet ist. Danach wird von mindestens einem Sensor zum Detektieren des Fahrverhaltens des Kraftfahrzeuges ein Signal an die Verstelleinrichtung gesendet, die daraufhin automatisch das Sicherungselement verstellt, insbesondere eine Vibrationsbewegung des Sicherungselements bewirkt.The object of the invention is further achieved by a method according to claim 21 for driving a safety device according to the invention, which is associated with a motor vehicle seat of a motor vehicle. Thereafter, a signal is sent to at least one sensor for detecting the driving behavior of the motor vehicle to the adjusting device, which then automatically adjusts the securing element, in particular causes a vibration movement of the securing element.
Die erfindungsgemäße Sicherheitsvorrichtung stellt ein System zur Verfügung, welches gleichzeitig als leistungsfähiges Komfort-, Warn- und Rückhaltesystem fungieren kann und erweitert die Funktionen der aus dem Dokument WO 2004/007237 bekannten "Reversiblen Aktiven Sitzrampe".The safety device according to the invention provides a system which can simultaneously function as a powerful comfort, warning and restraint system and extends the functions of the "reversible active seat ramp" known from document WO 2004/007237.

Figur 1 zeigt einen schematischen Querschnitt durch einen Kraftfahrzeugsitz 1 , in den eine Sicherheitsvorrichtung integriert ist. Der Kraftfahrzeugsitz 1 weist eine Lehne 10 sowie eine sich entlang einer Fahrzeuglängsachse X (und zugleich der Sitzlängsrichtung) erstreckende Sitzfläche 3 auf, auf der eine Person 2 Platz nehmen kann, für die ein Sicherheitsgurt 11 zum Angurten vorgesehen ist.Figure 1 shows a schematic cross section through a motor vehicle seat 1, in which a safety device is integrated. The motor vehicle seat 1 has a backrest 10 as well as a seat surface 3 extending along a vehicle longitudinal axis X (and at the same time the seat longitudinal direction) on which a person 2 can sit, for which a safety belt 11 is provided for fastening.
Die Sicherungsvorrichtung weist neben der Sitzfläche 3 ein Sicherungselement 4 auf, das unterhalb einer Polsterung der Sitzfläche 3 im Kraftfahrzeugsitz 1 angeordnet und integriert ist. Eine Verstelleinrichtung 5 ist über ein Getriebe mit dem Sicherungselement 4 gekoppelt. Das Sicherungselement 4 ist als quer zur Fahrzeuglängsachse X (Sitzlängsrichtung) verlaufendes (schalen- oder balkenartiges) Element ausgebildet (vgl. Figuren 2, 3, 4a und 4b), das von unten an die Polsterung der Sitzfläche angelenkt ist und über die Verstelleinrichtung 5 in unterschiedlichen Positionen relativ zur Sitzfläche 3 eingestellt werden kann. Dabei kann es gegebenenfalls zu einer gewissen Deformation der Sitzfläche 3 kommen. Allerdings wird hierbei nicht die räumliche Lage der Sitzfläche 3 als Ganzes (etwa durch ein Verschwenken) verändert, sondern nur deren Form und Härte (durch Bildung einer Sitzrampe). Während gemäß Figur 1 das Sicherungselement 4 im (in Sitzlängsrichtung betrachtet) mittleren Bereich der Sitzschale angeordnet ist, bildet es gemäß Figur 2 den vorderen Bereich der Sitzschale selbst.The securing device has, in addition to the seat surface 3, a securing element 4 which is arranged and integrated beneath a padding of the seat surface 3 in the motor vehicle seat 1. An adjusting device 5 is coupled via a transmission with the securing element 4. The securing element 4 is designed as a (shell-like or bar-like) element extending transversely to the vehicle longitudinal axis X (seat longitudinal direction) (see FIGS. 2, 3, 4a and 4b), which is articulated from below to the upholstery of the seat surface and via the adjusting device 5 in FIG different positions relative to the seat 3 can be adjusted. It may possibly come to a certain deformation of the seat 3. However, this does not change the spatial position of the seat 3 as a whole (for example, by pivoting), but only its shape and hardness (by forming a seat ramp). While according to Figure 1, the securing element 4 is arranged in the (viewed in the seat longitudinal direction) central portion of the seat, it forms according to Figure 2, the front portion of the seat itself.
Das Sicherungselement 4 ist verschiebbar ausgebildet und zwischen einer Ruheposition R und einer Sicherungsposition S verstellbar, vergl. in Figur 2, die die Umkehrpunkte der Verschiebungsbewegung des Sicherungselements 4 bilden. In der Ruheposition R ist das Sicherungselement 4 am weitesten von der Sitzfläche 3 entfernt, in der Sicherungsposition S ist das Sicherungselement 4 zur Erzeugung einer Sitzrampe maximal in das Sitzpolster der Sitzfläche 3 hereingedrückt. In der Sicherungsposition S wirkt das Sicherungselement 4 auf die Sitzfläche 3 ein, ohne dessen Lage relativ zum Sitz zu verändern, damit die Sitzfläche 3 und das Sicherungselement 4 zusammen (durch Bildung einer Sitzrampe) verhindern, dass die mit dem Sicherheitsgurt 11 des Fahrzeugsitzes 3 angegurtete Person 2 bei einer Crash-bedingten Vorverlagerung in Fahrtrichtung X unter dem Sicherheitsgurt 11 , speziell dessen Beckengurt, hindurchtaucht.The securing element 4 is designed to be displaceable and adjustable between a rest position R and a securing position S, cf. FIG. 2, which form the reversal points of the displacement movement of the securing element 4. In the rest position R, the securing element 4 is furthest away from the seating surface 3; in the securing position S, the securing element 4 is pushed in to the maximum extent into the seat cushion 3 of the seat surface 3 in order to produce a seat ramp. In the securing position S, the securing element 4 acts on the seat surface 3, without changing its position relative to the seat, so that the seat surface 3 and the securing element 4 together (by forming a seat ramp) prevent that belted with the seat belt 11 of the vehicle seat 3 Person 2 in a crash-related advancement in the direction of travel X under the seat belt 11, especially the lap belt, submerged.
Zwischen der Ruheposition R und der Sicherungsposition S besitzt das Sicherungselement 4 so viele Zwischenpositionen Z, dass es im Wesentlichen stufenlos zwischen der Ruheposition R und der Sicherungsposition S verstellbar ist.Between the rest position R and the securing position S, the securing element 4 has so many intermediate positions Z that it can be adjusted substantially continuously between the rest position R and the securing position S.
Die Verstellbewegung des Sicherungselements 4 erfolgt in dem in den Figuren dargestellten Ausführungsbeispiel linear, sie kann aber alternativ auch entlang einer anderen Bahnbewegung erfolgen.The adjustment movement of the securing element 4 takes place linearly in the exemplary embodiment shown in the figures, but alternatively it can also take place along another path movement.
Die Position des Sicherungselements 4 beeinflusst die Sitzhärte der Sitzfläche 3 und kann mittels der Verstellvorrichtung 5 eingestellt werden. Das Sicherungselement 4 kann aufgrund seiner Verschiebbarkeit weiter entfernt von Becken und Oberschenkel platziert werden, was eine höhere Schaumdicke der Sitzfläche 3 bewirkt und für einen besseren Sitzkomfort dient. Die Verstellvorrichtung 5 kann manuell bedient oder über ein nicht dargestelltes Betätigungselement angesteuert werden, das mit der Verstellvorrichtung 5 so gekoppelt ist, dass diese das Sicherungselement 4 in die gewünschte Position bewegt.The position of the securing element 4 influences the seat hardness of the seat surface 3 and can be adjusted by means of the adjusting device 5. Due to its displaceability, the securing element 4 can be placed farther away from the pelvis and thigh, which causes a higher foam thickness of the seat surface 3 and for a better Seating comfort is used. The adjusting device 5 can be operated manually or controlled via an actuating element, not shown, which is coupled to the adjusting device 5 so that it moves the securing element 4 in the desired position.
Die Verstelleinrichtung 5 ist so ausgebildet, dass sie in einem Crash-Fall das Sicherungselement 4 automatisch näher an die Sitzfläche 3 heranführt, so dass die Sitzfläche 3 und das Sicherungselement 4 eine im Wesentlichen entlang der Erstreckungsrichtung des Sicherungselements 4 quer zur Fahrtrichtung X wirksame Schwelle bilden, die dem Vorverlagern des Beckens einer auf dem Kraftfahrzeugsitz sitzenden Person 2 entlang der gesamten Breite des Kraftfahrzeugsitzes 1 entgegenwirken.The adjustment device 5 is designed so that it automatically brings the securing element 4 closer to the seat surface 3 in a crash, so that the seat surface 3 and the securing element 4 form a substantially along the extension direction of the securing element 4 transverse to the direction X effective threshold , which counteract the Vorverlagern of the pelvis of a person sitting on the motor vehicle seat 2 along the entire width of the vehicle seat 1.
Der Crash-Fall wird durch Sensoren festgestellt bzw. durch ein Pre-Crash System detektiert, das den Unfall bereits vor dessen Eintreten detektiert und daraufhin ein Signal an die Verstelleinrichtung 5 sendet, die das Sicherungselement 4 unmittelbar vor dem Unfall aus seiner eingestellten Position in die Sicherungsposition S verstellt, um so eine frühzeitige Rückhaltung der Person 2 zu gewährleisten und ein Submarining zu vermeiden.The crash case is detected by sensors or detected by a pre-crash system that detects the accident before it occurs and then sends a signal to the adjusting device 5, the fuse element 4 immediately before the accident from its set position in the Adjusting position S adjusted so as to ensure early retention of the person 2 and to avoid submarining.
Die Figur 3 zeigt eine schematische Ansicht auf das Sicherungselement 4 der Figuren 1 und 2, anhand der eine weitere Funktion der Sicherheitsvorrichtung beschrieben wird. Das Sicherungselement 4 ist als Balken ausgebildet, der über zwei Stangen eines Gestänges 8 mit zwei Verstellmotoren 6 gekoppelt ist. Dabei erstreckt sich das Gestänge 8 entlang der Verstellrichtung des Sicherungselements.FIG. 3 shows a schematic view of the securing element 4 of FIGS. 1 and 2, with reference to which a further function of the safety device will be described. The securing element 4 is designed as a bar, which is coupled via two rods of a linkage 8 with two adjusting motors 6. In this case, the linkage 8 extends along the adjustment direction of the securing element.
Die Verstellmotoren 6 wirken über Zahnräder 7 auf das Gestänge 8 derart ein, dass es entlang seiner Erstreckungsrichtung verschoben wird. Die Verstellmotoren 8 sind Teil der Verstelleinrichtung 5. Werden sie betätigt, wird das Gestänge 8 verschoben und die Position des damit verbundenen Sicherungselements 4 verändert.The adjusting motors 6 act via gears 7 on the linkage 8 such that it is displaced along its extension direction. The adjusting motors 8 are part of the adjusting device 5. If they are actuated, the linkage 8 is displaced and the position of the associated securing element 4 is changed.
Warnen nicht dargestellte Sensoren des Kraftfahrzeuges vor einer Gefahrensituation, insbesondere einem Auffahrunfall bzw. vor einem zu geringen Sicherheitsabstand, so werden die Verstellmotoren 6 automatisch betätigt. Sie wechseln rhythmisch ihre Drehrichtung und erzeugen über die Zahnräder 7 eine Vibrationsbewegung des Gestänges 8. Das Gestänge 8 überträgt die Vibrationsbewegung auf das Sicherungselement 4, das so auf die Polsterung der Sitzfläche 3 einwirkt, dass für die auf dem Kraftfahrzeugsitz 1 befindliche Person 2 ein haptisches Warnsignal in Form eines vibrierenden Sitzes wahrnehmbar ist. Das Sicherungselement 4 bewegt sich dabei zwischen der eingestellten Zwischenposition Z und einer davon beabstandeten Zwischenposition Z' hin- und her. Die Vibrationsbewegung kann auch um die Ruheposition R und die Sicherungsposition S herum erfolgen, wenn das Sicherungselement 4 in der Warnsituation in dieser Position eingestellt ist.Warn not shown sensors of the motor vehicle in front of a dangerous situation, especially a rear-end collision or too small safety distance, the adjusting motors 6 are automatically actuated. They rhythmically change their direction of rotation and generate via the gears 7 a vibratory movement of the linkage 8. The linkage 8 transmits the vibratory motion to the Securing element 4, which acts on the upholstery of the seat 3, that for the person 2 located on the vehicle seat 1, a haptic warning signal in the form of a vibrating seat is perceptible. The securing element 4 thereby moves back and forth between the adjusted intermediate position Z and an intermediate position Z 'spaced therefrom. The vibration movement can also take place around the rest position R and the securing position S, when the securing element 4 is set in the warning situation in this position.
Die Figuren 4a und 4b zeigen wie die Figur 3 eine schematische Ansicht auf das Sicherungselement 4. Die Verstellmotoren 6 bestehen aus einem rechten Verstellmotor 6a und einem linken Verstellmotor 6b. Diese Verstellmotoren 6a und 6b sind einzeln ansteuerbar. Gemäß Figur 4a wird nur der rechte Verstellmotor 6a angesteuert und bewegt über die rechte Stange 8a des Gestänges 8 die rechte Seite 4a des Sicherungselements 4, die eine Vibrationsbewegung ausführt.FIGS. 4a and 4b, like FIG. 3, show a schematic view of the securing element 4. The adjusting motors 6 consist of a right adjusting motor 6a and a left adjusting motor 6b. These adjusting motors 6a and 6b are individually controllable. According to FIG. 4a, only the right-hand adjusting motor 6a is actuated, and via the right-hand rod 8a of the linkage 8 moves the right-hand side 4a of the securing element 4, which performs a vibratory movement.
Analog dazu wird in der in Figur 4b gezeigten Situation nur der linke Verstellmotor 6b angesteuert, der die linke Seite 4b des Sicherungselements 4 zu einer Vibrationsbewegung veranlasst.Analogously, in the situation shown in FIG. 4b only the left adjusting motor 6b is actuated, which causes the left side 4b of the securing element 4 to vibrate.
Eine solche einseitige Vibrationsbewegung auf der linken oder rechten Seite ist für die auf dem Kraftfahrzeugsitz 1 befindliche Person 2 auch nur in der entsprechenden Sitzseite als Warnsignal zu fühlen. Ein solches Warnsignal wird automatisch bewirkt, wenn das Kraftfahrzeug von der vorgeschriebenen Fahrspur abkommt oder abzukommen droht. Dabei korreliert die Seite, an der das Fahrzeug von der Spur abkommt mit der Sitzseite, in der das Warnsignal ausgelöst wird.Such a unilateral vibration movement on the left or right side is to feel for the person located on the vehicle seat 1 2 only in the corresponding seat side as a warning signal. Such a warning signal is automatically effected when the motor vehicle departs from the prescribed lane or threatens to come off. The page at which the vehicle leaves the track correlates with the seat side in which the warning signal is triggered.
Beim unabsichtlichem Verlassen der Fahrspur nach rechts oder links kann die rechtsseitige oder linksseitige oszillierende Bewegung des Sicherungselementes 4 zur Warnung oder Aufforderung des Fahrers, die Spur zu korrigieren, ausgenutzt werden. Dies setzt eine spezielle Sensorik (z.B. Video) voraus, die der Verstelleinrichtung 5 das Signal zum Ausführen der Vibrationsbewegung übersendet.When unintentionally leaving the lane to the right or left, the right-hand or left-hand oscillating movement of the securing element 4 can be used to warn or prompt the driver to correct the lane. This implies a special sensor (e.g., video) which sends the adjusting means 5 the signal to carry out the vibratory motion.
Zur Verbesserung des Seitenhalts bei Kurvenfahrten kann die Sitzhärte in Abhängigkeit von der Kurvengeschwindigkeit und der Fahrtrichtungsänderung auch automatisch einseitig verändert werden. In diesem Fall erfolgt die beschriebene rechts- 'bzw. linksseitige Bewegung des Sicherungselementes 4 nicht oszillierend sondern stetig. Damit das Sicherungselement 4 eine einseitige Bewegung ausführen kann, ist der Ankoppelpunkt mit dem Gestänge 8 mit Spiel versehen und nicht als starre Verbindung ausgeführt. To improve the lateral support when cornering, the seat hardness can also be automatically adjusted on one side depending on the cornering speed and the direction of travel change. In this case, the right-described 'and left-side movement is carried out of the fuse element 4 is not oscillating but steadily. So that the securing element 4 can perform a one-sided movement, the coupling point is provided with the linkage 8 with play and not designed as a rigid connection.
