Description

Fahrzeugsitz  vehicle seat
TECHNISCHES GEBIET TECHNICAL AREA
Die Erfindung betrifft einen Fahrzeugsitz gemäß dem Oberbegriff des Patentanspruchs 1 . Sie betrifft weiterhin ein Fahrzeug mit einem derartigen Fahrzeugsitz. The invention relates to a vehicle seat according to the preamble of patent claim 1. It further relates to a vehicle with such a vehicle seat.
HINTERGRUND DER ERFINDUNG BACKGROUND OF THE INVENTION
Fahrzeugsitze sollen Fahrzeugpassagiere komfortabel und sicher im Fahrzeug positionieren. Außerdem muss der als Fahrersitz vorgesehene Fahrzeugsitz so verstellbar sein, dass große und kleine Menschen Lenkrad und Pedalerie durch entsprechende Anpassung der Sitzeinstellung erreichen. Vorgesehen sind dazu Längs-, Höhen- und Lehnenneigungsverstellungen. Die Längsverstellbarkeit wird bei Fahrzeugsitzen üblicherweise durch Lagerung des Sitzes auf Sitzschienen gewährleistet. Für nicht an der Fahrzeugführung beteiligte Fahrzeugpassagiere wird häufig auch gefordert, eine Ruhe- oder Liegesitzstellung des Fahrzeugsitzes zu ermöglichen. Zwar ist es bekannt, für eine Liegesitzposition oder eine bequeme zurückgelehnte Sitzposition die Rückenlehne des Fahrzeugsitzes in einen flacheren Winkel zu verstellen, doch bleibt dabei üblicherweise der Sitzboden, d.h. das Sitzteil, auf dem die Person sitzt, in derselben Stellung wie bei einer aufrecht stehenden Rückenlehne. Um eine möglichst bequeme Ruhe- oder Liegesitzposition einzunehmen, sollte jedoch auch das Sitzteil des Fahrzeugsitzes mit seinem vorderen, von der Rückenlehne abgewandten Ende nach oben aufgestellt werden. Zwar ist es grundsätzlich möglich, mittels einer in vielen Fahrzeugsitzen vorhandenen Sitzneigungsverstellung die Neigung des Sitzkissens unabhängig von der Lehnenneigung zu verstellen, doch wird durch eine solche separate Verstellung von Sitzboden und Rückenlehne in eine Ruhe- oder Liegesitzposition das spätere Zurückführen des Sitzes in eine aufrechte Sitzposition erschwert. Vehicle seats are intended to position vehicle passengers comfortably and safely in the vehicle. In addition, the intended as a driver's seat vehicle seat must be adjustable so that large and small people reach the steering wheel and pedals by adjusting the seat adjustment. Provided for this are longitudinal, vertical and backrest inclination adjustments. The longitudinal adjustability is usually ensured in vehicle seats by mounting the seat on seat rails. For not involved in the vehicle management vehicle passengers is often required to allow a rest or reclining position of the vehicle seat. While it is known to adjust the backrest of the vehicle seat to a shallower angle for a reclining seating position or a comfortable reclined seating position, the seat bottom, ie, the seat portion on which the occupant sits, usually remains in the same position as an upright backrest , For the most comfortable resting or reclining position However, should also be the seat part of the vehicle seat with its front, facing away from the back end facing up. Although it is in principle possible to adjust the inclination of the seat cushion independently of the backrest inclination by means of a seat angle adjustment present in many vehicle seats, such a separate adjustment of the seat bottom and backrest into a rest or reclining position will subsequently return the seat to an upright sitting position difficult.
DARSTELLUNG DER ERFINDUNG PRESENTATION OF THE INVENTION
Aufgabe der vorliegenden Erfindung ist es daher, einen gattungsgemäßen Fahrzeugsitz so auszugestalten, dass eine Neigung des gesamten Fahrzeugsitzes aus einer Normalposition in eine Ruhe- oder Liegesitzposition und ein Zurückverstellen in die Normalposition schnell und komplikationslos möglich sind. Object of the present invention is therefore to provide a generic vehicle seat in such a way that an inclination of the entire vehicle seat from a normal position in a rest or Liegesitzposition and Zurückverstellen in the normal position quickly and without complications are possible.
Diese Aufgabe wird gelöst mit den Merkmalen des Patentanspruchs 1 . This object is achieved with the features of patent claim 1.
Der erfindungsgemäße Fahrzeugsitz ist versehen mit einem Sitzteil und einer daran angebrachten Rückenlehne. Der Fahrzeugsitz ist aus einer im Wesentlichen aufrechten Sitzposition in eine Ruhe- oder Liegesitzposition verlagerbar. Es ist eine Höhenverstelleinrichtung vorgesehen, die ein vorderes Höhenverstellelement und ein hinteres Höhenverstellelement aufweist, das jeweils an einem oberen Schwenkgelenk mit einem Sitzboden im Sitzteil des Fahrzeugsitzes und an einem unteren Schwenkgelenk mit einem fahrzeugstrukturseitigen Sitzkonsolenelement gekoppelt ist und das jeweils zur Einstellung der Höhe und der Neigung des Sitzteils mittels einer jeweiligen Höhenverstelleinrichtung verstellbar ist. Erfindungsgemäß ist dabei vorgesehen, dass zusätzlich zur Höhenverstelleinrichtung eine unabhängig von dieser betätigbare Kippverstelleinrichtung vorgesehen ist, die das vordere Höhenverstellelement aufweist und mit der der Abstand zwischen dem oberen Schwenkgelenk und dem unteren Schwenkgelenk des vorderen Höhenverstellelements veränderbar ist. The vehicle seat according to the invention is provided with a seat part and a backrest attached thereto. The vehicle seat is displaceable from a substantially upright sitting position to a resting or reclining position. A height adjustment device is provided which has a front height adjustment element and a rear height adjustment element which is coupled in each case to an upper pivot joint with a seat bottom in the seat part of the vehicle seat and at a lower pivot joint with a vehicle body side seat console element and each for adjusting the height and inclination the seat part is adjustable by means of a respective height adjustment device. According to the invention it is provided that in addition to the height adjustment device is provided independently of this actuatable Kippverstelleinrichtung that the front Has height adjustment and with which the distance between the upper pivot joint and the lower pivot joint of the front Höhenverstellelements is variable.
VORTEILE ADVANTAGES
In der aufrechten Sitzposition ("Normalposition") ist der Fahrzeugsitz an die Körpermaße und Bedürfnisse der auf dem Fahrzeugsitz sitzenden Person individuell angepasst, was insbesondere beim Fahrersitz von Bedeutung ist. Nach einer zeitweiligen Nutzung des Fahrzeugsitzes als Ruhe- oder Liegesitz sollte der Fahrzeugsitz schnellstmöglich wieder in diese Normalposition zurückverstellbar sein, sodass die Person nicht erst wieder die für sie geeignete Normalposition aufwändig ermitteln und einstellen muss. Dies ist insbesondere dann erforderlich, wenn nach einer Fahrstrecke, in der das Fahrzeug autonom pilotiert worden ist, der Fahrer wieder die Steuerung des Fahrzeugs übernehmen muss. Diese Anforderung wird mit dem Fahrzeugsitz gemäß der Erfindung erfüllt, da die Kippverstelleinrichtung, die eine Neigung des Fahrzeugsitzes in die Ruhe- oder Liegesitzposition ermöglicht, unabhängig von der Höhenverstelleinrichtung und damit unabhängig von Komponenten der Sitzverstelleinrichtung betätigbar ausgebildet ist. In the upright sitting position ("normal position"), the vehicle seat is individually adapted to the body dimensions and needs of the person sitting on the vehicle seat, which is particularly important in the driver's seat. After a temporary use of the vehicle seat as a rest or reclining seat of the vehicle seat should be back as quickly as possible back to this normal position, so that the person does not first again consuming the appropriate normal position to determine and adjust. This is necessary in particular if, after a route in which the vehicle has been autonomously piloted, the driver must again take over control of the vehicle. This requirement is met with the vehicle seat according to the invention, since the Kippverstelleinrichtung, which allows an inclination of the vehicle seat in the rest or reclining position, regardless of the height adjustment device and thus independently of components of the seat adjustment is formed operable.
Weitere bevorzugte und vorteilhafte Ausgestaltungsmerkmale des erfindungsgemäßen Fahrzeugsitzes sind Gegenstand der Unteransprüche 2 bis 6. Further preferred and advantageous design features of the vehicle seat according to the invention are the subject of the dependent claims 2 to 6.
Vorzugsweise weist die Kippverstelleinrichtung einen Verlängerungsmechanismus für das vordere Höhenverstellelement auf. Preferably, the Kippverstelleinrichtung has an extension mechanism for the front height adjustment.
Von Vorteil ist es dabei, wenn der Verlängerungsmechanismus einen Spindeltrieb aufweist. Alternativ kann der Verlängerungsmechanismus ein Mehrgelenkgetriebe, insbesondere ein Viergelenkgetriebe, aufweisen. It is advantageous if the extension mechanism has a spindle drive. Alternatively, the extension mechanism may comprise a multi-link transmission, in particular a four-bar linkage.
In einer vorteilhaften Weiterbildung weist das vordere Höhenverstellelement einen mehrteilig ausgebildeten Lenker auf, dessen einer Teil die Höhenverstelleinrichtung bildet oder aufnimmt und dessen zumindest einer weiterer Teil den Verlängerungsmechanismus bildet. In an advantageous development, the front height adjustment element has a multi-part handlebar, one part of which forms or absorbs the height adjustment device and whose at least one further part forms the extension mechanism.
Ebenfalls von Vorteil ist es, wenn das vordere Höhenverstellelement einen hydraulisch, pneumatisch, elektrisch oder elektromagnetisch wirkenden Aktuator aufweist, der den Verlängerungsmechanismus betätigt. It is also advantageous if the front height adjustment element has a hydraulically, pneumatically, electrically or electromagnetically acting actuator which actuates the extension mechanism.
