Stand der Technik State of the art
Die vorliegende Erfindung betrifft einen Fahrzeugsitz mit einem Sitzteil und einer Rückenlehne, bei der das Sitzteil und die Rückenlehne von einer Gebrauchs- in eine Einstiegs- und in eine Ladeposition verstellbar sind. The present invention relates to a vehicle seat with a seat part and a backrest, in which the seat part and the backrest are adjustable from a used to an entry and into a loading position.
Derartige Fahrzeugsitze sind aus dem Stand der Technik bekannt. In der Gebrauchsposition kann ein Fahrzeuginsasse auf dem Sitzteil des Fahrzeugsitzes Platz nehmen. In der Einstiegsposition werden das Sitzteil und die Rückenlehne so verstellt, dass sich der Einstiegsraum hinter dem Fahrzeugsitz vergrößert. In der Ladeposition soll die Rückenlehne im Wesentlichen so angeordnet sein, dass eine ebene Ladefläche mit dem Laderaum entsteht. Da die Bauraumverhältnisse in den meisten Kraftfahrzeugen sehr begrenzt sind, ist insbesondere eine ebene Ladefläche in der Regel nicht gegeben. Such vehicle seats are known from the prior art. In the use position, a vehicle occupant can sit on the seat part of the vehicle seat. In the entry position, the seat part and the backrest are adjusted so that increases the entry space behind the vehicle seat. In the loading position, the backrest should essentially be arranged in such a way that a flat loading area is created with the loading space. Since the space conditions are very limited in most motor vehicles, in particular a flat cargo area is usually not given.
Offenbarung der Erfindung Disclosure of the invention
Es war deshalb die Aufgabe der vorliegenden Erfindung, einen Fahrzeugsitz zur Verfügung zu stellen, der die Nachteile des Standes der Technik nicht aufweist. Insbe- sondere soll ein Fahrzeugsitz zur Verfügung gestellt werden, der vergleichsweise bauraumkompakt ausgebildet ist, eine Einhandbedienung beim Umklappen erlaubt, in der Ladeposition eine möglichst große Ladefläche bereitstellt, einen großen Einstiegsraum gewährleistet und kostengünstig zu realisieren ist. Gelöst wird die Aufgabe mit einem Fahrzeugsitz mit einem Sitzteil und einer Rückenlehne, bei dem das Sitzteil und die Rückenlehne von einer Gebrauchs- in eine Einstiegs- und in eine Ladeposition verstellbar sind, wobei die Rückenlehne an einem Fuß beweglich gelagert ist und das Sitzteil in der Gebrauchsposition an einer vorde- ren Lagerung und an dem Fuß gelagert ist und die vordere Lagerung und der Fuß jeweils unabhängig voneinander sowie relativ zu der Fahrzeugkarosserie bewegbar sind. Die vorliegende Erfindung betrifft einen Fahrzeugsitz für ein Kraftfahrzeug. Derartige Fahrzeugsitze weisen ein Sitzteil und eine Rückenlehne auf. Der Fahrzeugsitz kann einer oder mehreren Personen Platz bieten. In seiner Gebrauchsposition ist das Sitzteil im Wesentlichen horizontal und die Rückenlehne im Wesentlichen vertikal vorgesehen. Von dieser Gebrauchsposition können das Sitzteil und die Rückenlehne zum einen in eine Einstiegs- und zum anderen in eine Ladeposition verbracht werden. In der Einstiegsposition werden zumindest Teile des Fahrzeugsitzes so verstellt, dass der Raum hinter der Rückenlehne des Fahrzeugsitzes vergrößert wird, um das Einsteigen von Fahrzeuginsassen, die hinter dem erfindungsgemäßen Fahrzeugsitz Platz nehmen möchten, zu erleichtern. In der Ladeposition wird insbesondere die Rü- ckenlehne von der Vertikalen in die Horizontale verstellt, um eine ebene Ladefläche mit dem Laderaum des Fahrzeuges zu erzeugen, wobei dabei insbesondere das Sitzteil nicht im Weg sein darf und gemäß der vorliegenden Erfindung dafür abgesenkt wird. Erfindungsgemäß ist nun die Rückenlehne des Fahrzeugsitzes an einem Fuß beweglich, insbesondere drehbar, gelagert. Diese Bewegung dient vorzugsweise auch für eine sogenannte Komfortverstellung, um die Rückenlehne an die Physionomie des Sitzinsassen anzupassen. Das Sitzteil ist in seiner Gebrauchsposition in seinem vorderen Bereich an einer vorderen Lagerung, insbesondere einer Schwinge, und in seinem hinteren Bereich an dem Fuß, an dem auch die Rückenlehne vorgesehen ist, gelagert. Weiterhin erfindungsgemäß sind die vordere Lagerung und der Fuß jeweils unabhängig voneinander sowie relativ zu der Fahrzeugkarosserie bewegbar. It was therefore the object of the present invention to provide a vehicle seat which does not have the disadvantages of the prior art. In particular, a vehicle seat is to be made available, which is comparatively space-compact, allows one-handed operation when folding, provides the largest possible loading area in the loading position, ensures a large boarding room and is inexpensive to implement. The object is achieved with a vehicle seat with a seat part and a backrest, in which the seat part and the backrest of a utility in an entry and a loading position are adjustable, the backrest is movably mounted on a foot and the seat part in the Use position on a front Ren storage and is mounted on the foot and the front storage and the foot are each independently and relative to the vehicle body movable. The present invention relates to a vehicle seat for a motor vehicle. Such vehicle seats have a seat part and a backrest. The vehicle seat can accommodate one or more persons. In its use position, the seat part is substantially horizontal and the backrest is provided substantially vertically. From this position of use, the seat part and the backrest can be spent on the one hand in an entry and the other in a loading position. In the entry position, at least parts of the vehicle seat are adjusted so that the space behind the backrest of the vehicle seat is increased in order to facilitate the boarding of vehicle occupants who want to take a seat behind the vehicle seat according to the invention. In the loading position, in particular, the backrest is adjusted from the vertical to the horizontal in order to produce a flat loading area with the loading space of the vehicle, wherein in particular the seat portion must not be in the way and lowered according to the present invention. According to the invention, the backrest of the vehicle seat is now movable on a foot, in particular rotatably mounted. This movement is preferably also used for a so-called comfort adjustment in order to adapt the backrest to the physiognomy of the seat occupant. The seat part is in its use position in its front region on a front bearing, in particular a rocker, and in its rear region on the foot, on which the backrest is provided, stored. Furthermore, according to the invention, the front bearing and the foot are each movable independently of one another and relative to the vehicle body.
Dadurch ist eine sehr kompakte Bauweise möglich und das Sitzteil kann unabhängig von der Rückenlehne in die jeweils gewünschte Position verbracht werden. This makes a very compact design possible and the seat part can be spent regardless of the backrest in the desired position.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen sowie der Beschreibung unter Bezugnahme auf die Zeichnungen entnehmbar. Vorzugsweise weist das Sitzteil in seinem hinteren Bereich, in dem sich das Gesäß des Sitzinsassen befindet, ein Führungsmittel, beispielsweise einen Bolzen, auf, der mit einer Führung, beispielsweise einer Kulisse, die an dem Fuß vorgesehen ist, zusammenwirkt und entlang dieser Kulisse bewegt wird, beispielsweise linear verscho- ben werden kann. Dadurch ist es möglich, das Sitzteil unabhängig von dem Fuß zu bewegen. Advantageous embodiments and modifications of the invention are the dependent claims and the description with reference to the drawings. Preferably, the seat part in its rear area, in which the buttocks of the seat occupant is, a guide means, such as a bolt, which cooperates with a guide, for example a gate, which is provided on the foot, and is moved along this backdrop , for example, can be shifted linearly. This makes it possible to move the seat part independently of the foot.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass die Führung eine Öffnung, über die das Führungsmittel die Führung bei einer Überführung des Fahrzeugsitzes von der Gebrauchsposition in die Lade- bzw. Einstiegsposition verlässt, aufweist. Insbesondere umfasst die Kulisse eine Kulissenöffnung beispielsweise an dessen Oberseite, über die der Bolzen die Kulissenführung für die Einnahme der Einstiegsposition verlässt. Darüber hinaus ist vorzugsweise vorgesehen, dass das Führungsmittel in der Gebrauchsstellung im Bereich der Öff- nung angeordnet ist, insbesondere unmittelbar unter der Öffnung angeordnet ist. Dadurch lässt sich ohne großen zusätzlichen Aufwand dafür sorgen, dass das Führungsmittel die Führung verlässt, wenn der Fahrzeugsitz in die Ladeposition überführt werden soll. Weiterhin ist es vorgesehen der Bolzen in der Einstiegsposition außerhalb der Kulisse und in der Gebrauchs- und Ladeposition innerhalb der Kulisse angeordnet ist. According to a further embodiment of the present invention, it is provided that the guide has an opening, via which the guide means leaves the guide during a transfer of the vehicle seat from the use position to the loading or entry position. In particular, the backdrop includes a gate opening, for example, at the top, via which the bolt leaves the slotted guide for taking the entry position. In addition, it is preferably provided that the guide means is arranged in the use position in the region of the opening, in particular is arranged directly below the opening. This makes it possible without much additional effort that the guide means leaves the guide when the vehicle seat is to be transferred to the loading position. Furthermore, it is provided that the bolt is arranged in the entry position outside the scenery and in the use and loading position within the backdrop.
Vorzugsweise sind sowohl die vordere Lagerung als auch der Fuß mit einem Preferably, both the front bearing and the foot with a

In its rear area, in which the buttocks of the seat occupant is provided, the seat part 3 is also mounted on the foot 5. The foot 5 is connected to the longitudinal adjustment 6, in the present case by means of two bearings, the middle bearing 5.1 and the rear bearing 5.2. Both the front bearing 3.2 and the middle and the rear bearing 5.1, 5.2 are each provided in the present case as a rocker, each having a lever which has at its first and at its second end in each case a pivot bearing. In the front rocker 3.2 is a pivot bearing with the seat part 3 and the other pivot bearing with the longitudinal adjustment. 6 connected. In the middle and rear rocker 5.1, 5.2 each have a pivot bearing with the foot 5 and the other pivot bearing with the longitudinal adjustment 6 is connected. The skilled person understands that the bearings 3.2, 5.1 and 5.3 can also be connected directly to the body, in the event that the vehicle seat according to the invention has no longitudinal adjustment. In its rear region, the seat part 3 in the present case, a guide / storage means 3.1, for example a bolt on which engages in the present case in the use position of the vehicle seat 1 in a guide 5.3, here a link, which the guide means 3.1 on the one hand leads and / or stores, but also allows a relative movement between the seat part 3 and the foot 5. Preferably, the guide 5.3 and / or the guide means 3.1 are provided so that the connection between the rear part of the seat part 3 and the foot 5 can be selectively released. Preferably, in the front region of the seat part 3, a drive 4, here an electric motor, is provided, with which it is possible to adjust the seat part 3 relative to the front bearing 3.2 and / or the front bearing 3.2 relative to the body of the vehicle.
Figur 1a zeigt den Fahrzeugsitz 1 in seiner sogenannten Gebrauchsposition, in der ein Fahrzeuginsasse auf dem Fahrzeugsitz 1 Platz nehmen kann. FIG. 1a shows the vehicle seat 1 in its so-called use position, in which a vehicle occupant can sit on the vehicle seat 1.
Figur 1 b zeigt die sogenannte Einstiegsposition. Dafür wird die Verbindung zwischen dem Sitzteil 3 und dem Fuß 5 gelöst und das Sitzteil 3 kann, beispielsweise mittels des Motors 4, von seiner im Wesentlichen horizontalen Lage in eine vertikale Position verstellt werden. Danach wird die Verbindung zwischen dem Fuß 5 und der Längsverstellung teilweise gelöst und der Fuß 5 kann, hier gegen den Uhrzeigersinn, in den von dem Sitzteil freigegebenen Raum verdreht werden. Dadurch entsteht hinter dem erfindungsgemäßen Fahrzeugsitz 1 mehr Platz, der den Sitzinsassen, die in der Sitzreihe hinter dem erfindungsgemäßen Fahrzeugsitz Platz nehmen, mehr Raum zum Einstieg gibt. Figure 1 b shows the so-called entry position. For the connection between the seat part 3 and the foot 5 is released and the seat part 3 can, for example by means of the motor 4, be adjusted from its substantially horizontal position to a vertical position. Thereafter, the connection between the foot 5 and the longitudinal adjustment is partially released and the foot 5 can be rotated, here counterclockwise, in the released from the seat part space. This creates behind the vehicle seat 1 according to the invention more space, which gives the seat occupants who sit in the row of seats behind the vehicle seat according to the invention, more room to board.
Figur 1c zeigt den erfindungsgemäßen Fahrzeugsitz 1 in seiner sogenannten Ladeposition, in der die Rückenlehne 2 im Wesentlichen horizontal vorgesehen ist. Dafür wird zunächst die vordere Lagerung 3.2 im Uhrzeigersinn gedreht, wodurch das Sitzteil 3, insbesondere dessen vorderer Bereich, zum einen abgesenkt, aber auch nach links, von dem Fuß 5 weg, verschoben wird. Dabei verschiebt sich der hintere Bereich des Sitzteils 3 entlang der Kulisse 5.3 und die Bewegung wird durch die Kulisse begrenzt. Durch diese Absenkung bzw. Verschiebung des Sitzteils 3 steht für die Rückenlehne 2 mehr Platz zur Verfügung, so dass diese zumindest annähernd horizon- tal und damit eben zu dem restlichen Laderaum vorgesehen werden kann. Figure 1c shows the vehicle seat 1 according to the invention in its so-called loading position, in which the backrest 2 is provided substantially horizontally. For this, first the front bearing 3.2 is rotated clockwise, whereby the seat part 3, in particular its front area, lowered for a, but also after left, away from the foot 5, is moved. In this case, the rear portion of the seat part 3 shifts along the backdrop 5.3 and the movement is limited by the backdrop. As a result of this lowering or displacement of the seat part 3, more space is available for the backrest 2, so that it can be provided at least approximately horizontally and thus just to the rest of the load compartment.
Figuren 2a bis 2c zeigen eine weitere Ausführungsform des erfindungsgemäßen Fahrzeugsitzes 1 . Im Wesentlichen kann auf die Ausführungen gemäß Figur 1 a - 1 c Bezug genommen werden, wobei in dem vorliegenden Fall der Elektromotor durch einen Linear-Antrieb, insbesondere einen pneumatischen oder hydraulischen Antrieb, ersetzt worden ist. Dieser Antrieb 4 wird zwischen der Längsverstellung 6 und dem Sitzteil 3 vorgesehen und kann dieses zum einen relativ zu der Lagerung 3.2 verdrehen. Der Antrieb 4 kann aber auch alternativ oder zusätzlich dazu eingesetzt werden, die vordere Lagerung 3.2 relativ zu der Längsverstellung zu verdrehen. Auch hier erkennt der Fachmann, dass eine Längsverstellung nicht unbedingt von- nöten ist, sondern die vordere Lagerung 3.2 bzw. der Fuß 5 auch direkt mit der Fahrzeugkarosserie verbunden sein kann. FIGS. 2 a to 2 c show a further embodiment of the vehicle seat 1 according to the invention. Essentially, reference may be made to the embodiments according to FIGS. 1a-1c, wherein in the present case the electric motor has been replaced by a linear drive, in particular a pneumatic or hydraulic drive. This drive 4 is provided between the longitudinal adjustment 6 and the seat part 3 and this can rotate relative to the storage 3.2 for a. However, the drive 4 can also be used alternatively or in addition to rotate the front bearing 3.2 relative to the longitudinal adjustment. Here, too, the person skilled in the art recognizes that a longitudinal adjustment is not absolutely necessary but the front bearing 3.2 or the foot 5 can also be connected directly to the vehicle body.
