Abstract
Fahrzeugsitz, insbesondere Kraftfahrzeugsitz, mit wenigstens einem Paar von automatisch einstellbaren Seitenwangen am Sitzteil und/oder an der Rückenlehne, wobei die Einsteller für die Seitenwangen in Abhängigkeit von Beschleunigungen des Fahrzeugsitzes betätigt werden, dadurch gekennzeichnet, dass bei Kurvenfahrten die kurvenäußere Seitenwange zum Sitzbenutzer hin bewegt und die kurveninnere Seitenwange vom Sitzbenutzer weg bewegt wird.Vehicle Seat, in particular motor vehicle seat, with at least one pair of automatic adjustable side cheeks on the seat part and / or on the backrest, being the adjuster for the side cheeks in dependence actuated by accelerations of the vehicle seat, characterized in that that when cornering the curve-side sideways towards the seat user out moved and moved the inside of the curve sideways away from the seat user becomes.
Description
Die Erfindung betrifft einen Fahrzeugsitz, insbesondere einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a vehicle seat, in particular a motor vehicle seat, with the features of the preamble of claim 1.
Bei
Kurvenfahrten wirken auf den Körper Querbeschleunigungswerte,
die von dem Sitzbenutzer durch eine entsprechende Haltekraft kompensiert werden
müssen.
Bekannte Fahrzeugsitze weisen hierfür erhöhte Seitenwangen auf, mit denen
ein besserer Seitenhalt erreicht wird. Der Sitzbenutzer hat dadurch
eine reduzierte Haltekraft aufzubringen. Gemäß der
Der Erfindung liegt die Aufgabe zu Grunde, einen Fahrzeugsitz der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch einen Fahrzeugsitz mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, a vehicle seat of the beginning to improve the type mentioned. This object is achieved by a vehicle seat with the features of claim 1 solved. advantageous Embodiments are the subject of the dependent claims.
Dadurch, dass bei Kurvenfahrten die kurvenäußere Seitenwange zum Sitzbenutzer hin bewegt und die kurveninnere Seitenwange vom Sitzbenutzer weg bewegt wird, wird der Seitenhalt verbessert durch eine angepasste Seitenabstützung mit einem gleichbleibenden, seitlichen Halt und Druck. Die Ausgleichsbewegung der kurveninneren Seitenwange verhindert dabei, dass der Sitzbenutzer auf der Kurveninnenseite belastet wird, und ermöglicht seinem Körper, in diese Richtung auszuweichen. Zusätzlich zu diesen automatisch beweglichen Seitenwangen kann eine drehbare, d.h. in ihrer Neigung einstellbare Sitzschale vorgesehen sein, die bei einer Kurvenfahrt die Gesäßunterstützung verbessern kann.Thereby, that when cornering the curve-side side cheek to the seat user moved away and the inside curve sideways away from the seat user is moved, the lateral support is improved by a customized side support with a consistent, lateral hold and pressure. The compensation movement the inside of the curve prevents the seat user from doing so on the inside of the turn is loaded, and allows his body, in to avoid this direction. In addition to These automatically movable side bolsters can be a rotatable, i.e. be provided in their inclination adjustable seat shell, the improve buttocks support when cornering can.
Im folgenden ist die Erfindung anhand eines Ausführungsbeispiels näher erläutert.in the The following is the invention with reference to an embodiment explained in more detail.
Im Ausführungsbeispiel weist ein Fahrzeugsitz für ein Kraftfahrzeug an seinem eine Sitzfläche definierenden Sitzteil und an seiner eine Lehnenfläche definierenden Rückenlehne jeweils Seitenwangen auf. Mittels Einsteller sind diese Seitenwangen relativ zur Sitzfläche bzw. zur Lehnenfläche einstellbar, beispielsweise in Bezug auf den Abstand der Seitenwangenoberkante relativ zu einer solchen Fläche („Höhe"), vorzugsweise aber in alle drei Raumrichtungen. Die Seitenwangen sind vorzugsweise unabhängig voneinander einstellbar, beispielsweise pneumatisch oder elektromotorisch. Das Sitzteil weist zur Aufnahme des Sitzpolsters eine Sitzschale auf, die vorzugsweise auf einstellbaren Blattfedern gelagert ist. Diese Blattfedern, im folgenden als Schwingfedern bezeichnet, können elektrisch oder pneumatisch einstellbar sein. Die verschiedenen Einsteller sind an eine gemeinsame Steuereinheit (oder jeweils an eine eigene Steuereinheit) angeschlossen, an welcher Beschleunigungssensoren für alle drei Raumrichtungen angeschlossen sind. Die Beschleunigungssensoren sind beispielsweise in den Seitenwangen angeordnet.in the embodiment has a vehicle seat for a motor vehicle at its seat part defining a seat and at its one back surface defining backrest each side cheeks on. By means of adjuster, these side cheeks are relative to the seat or to the backrest surface adjustable, for example, in relation to the distance of the side cheek top relative to such a surface ("Height"), but preferably in all three directions. The side cheeks are preferably independently adjustable from each other, for example pneumatically or by electric motor. The seat part has a seat shell for receiving the seat cushion, which is preferably mounted on adjustable leaf springs. These Leaf springs, hereinafter referred to as vibrating springs, can be electric or be pneumatically adjustable. The different adjusters are connected to a common control unit (or each to its own Control unit) connected to which acceleration sensors for all three spatial directions are connected. The acceleration sensors are arranged for example in the side walls.
Durch die Querbeschleunigung bei einer Kurvenfahrt regelt die Steuereinheit die Geschwindigkeit und den Weg der verschiedenen Einsteller so, dass eine Erhöhung des Seitenhalts des Sitzbenutzers erfolgt, wodurch eine optimale Anpassung und Unterstützung bei der Kurvenfahrt erreicht wird. Die kurvenäußeren Seitenwangen werden entgegen der Fliehkraft zum Sitzbenutzer hin und die kurveninneren Seitenwangen zum Ausgleich vom Sitzbenutzer weg bewegt. Die Bewegung kann dabei rein radial bezüglich der Kurve sein, ein Anheben der äußeren bzw. Absenken der inneren Seitenwange sein oder eine Kombination von beiden Möglichkeiten sein.By the lateral acceleration when cornering controls the control unit the speed and the way of the different adjuster so that an increase of the lateral support of the seat occupant, whereby an optimal Customization and support when cornering is achieved. The curve-side sidewalls are opposed the centrifugal force towards the seat user and the inside of the curve side bolsters moved to compensate for the seat user away. The movement can be purely radially with respect be the curve, a lifting of the outer or Lower the inner side panel or a combination of both ways be.
Mittels der einstellbaren Schwingfedern kann auch die Sitzschale durch Verdrehen oder Verkippen in ihrer Neigung der Kurvenfahrt angepaßt werden und damit die Gesäßabstützung geneigt werden. Vorzugsweise wird bei der Kurvenfahrt der kurvenäußere Rand der Sitzschale angehoben und der kurveninnere Rand abgesenkt.through The adjustable oscillating springs can also be used to turn the seat shell by turning it or tilting in their tendency to cornering and so that the buttocks support inclined become. Preferably, when cornering the outside edge of the curve raised the seat and lowered the inside edge of the curve.
Außer für die Kurvenfahrt können die einstellbaren Schwingfedern auch dazu eingesetzt werden, um durch Drehungen der Sitzschale über die Becken- und Wirbelbewegung die Bandscheiben zu massieren.Except for the cornering can The adjustable oscillating springs are also used to through rotations of the seat over the pelvic and vertebral movement to massage the intervertebral discs.
Für einen erleichterten Einstieg kann die Steuereinheit so programmiert sein, dass bei Beendigung der Fahrt die Einsteller die Seitenwangen in Parkstellungen in der Ebene der Sitzfläche bzw. der Lehnenfläche bewegen und bei Aufnahme der Fahrt die Seitenwangen aus diesen Ebenen heraus in ihre Gebrauchsstellungen fahren.For easier entry, the control unit can be programmed so that when the end of the ride, the adjuster move the side cheeks in parking positions in the plane of the seat or the backrest surface and when taking the ride, the side cheeks from these levels out in their Driving the operating positions.
