Abstract

The seat has a seat cushion (3) and an adjustable leg supports. The leg support consists of a foam part in some regions. The foam part comprises openings, which permit deformation of the foam part. The openings are distributed on the leg part in a transverse direction. The foam part and the leg part are provided with a pad material, which slides on the foam part during an adjustment of the leg part.

Description

Die Erfindung betrifft einen Fahrzeugsitz mit einer verstellbaren Schenkelauflage.The The invention relates to a vehicle seat with an adjustable leg rest.

Fahrzeugsitze mit einer verstellbaren Schenkelauflage sind im Stand der Technik hinlänglich bekannt. Dabei kann entweder die Schenkelauflage als Einzelteil oder als Verlängerung des Sitzkissens verstellt werden. Eine Sitztiefenverstellung kann auch durch ein Verschieben des kompletten Sitzkissens erfolgen. Die Verstellung ist sowohl manuell als auch elektrisch möglich.car seats with an adjustable leg rest are in the prior art adequately known. It can either the thigh support as a single part or as an extension be adjusted the seat cushion. A seat depth adjustment can also done by moving the entire seat cushion. The adjustment is possible both manually and electrically.

Wenn die Schenkelauflage als Einzelteil verschoben wird, entsteht zwischen der Hinterkante der Schenkelauflage und der Vorderkante des Sitzkissens ein Spalt, in dem sich Schmutz und Krümel sammeln können. Außerdem kann der Spalt eine Beeinträchtigung des Sitzkomforts mit sich bringen, er wirkt auch in optischer Hinsicht störend. Bei einer Verschiebung des gesamten Sitzkissens wird die Person in Verstellrichtung verschoben, was dazu zwingt in die vorherige Sitzposition nachzurücken.If the thigh support is moved as an item, arises between the trailing edge of the thigh support and the leading edge of the seat cushion a gap where dirt and crumbs can collect. In addition, can the gap an impairment of seating comfort, it also works optically disturbing. With a displacement of the entire seat cushion is the person shifted in the direction of adjustment, which forces to the previous one Nachzusücken seat position.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Fahrzeugsitz mit einer verstellbaren Schenkelauflage zu schaffen, welcher die Nachteile des Standes der Technik beseitigt und welcher den Sitzkomfort und das optische Erscheinungsbild erheblich verbessert.It is therefore an object of the present invention, a vehicle seat to provide with an adjustable leg rest, which the Disadvantages of the prior art eliminated and which the seating comfort and significantly improves the visual appearance.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen Fahrzeugsitz mit einem Sitzkissen und einer verstellbaren Schenkelauflage, wobei die Schenkelauflage aus einem Schaumteil besteht, welches eine bestimmte Anzahl von Durchbrüchen aufweist, die eine Verformung des Schaumteils erlauben.According to the invention this Task solved by a vehicle seat with a seat cushion and an adjustable Leg rest, wherein the leg rest of a foam part exists, which has a certain number of breakthroughs, which allow a deformation of the foam part.

Infolge dieser Ausgestaltung wird durch die Durchbrüche in der Schenkelauflage eine Stauchung und Dehnung in verschiedenen Richtungen ermöglicht, so dass allein durch eine Verformung der Schenkelauflage eine Verstellung der Schenkelauflage erreicht wird.As a result This embodiment is characterized by the openings in the leg rest allows compression and expansion in different directions so that solely by a deformation of the thigh support an adjustment the thigh support is reached.

Die Unteransprüche beinhalten vorteilhafte Weiterbildungen und Ausgestaltungen des Gegenstandes des Anspruchs 1.The under claims contain advantageous developments and refinements of Subject of claim 1.

Gemäß einer vorteilhaften Weiterbildung erlaubt das Schaumteil sowohl eine Stauchung als auch eine Dehnung in verschiedene Richtungen, vorzugsweise in der Länge und/oder in der Breite, so dass die Schenkelauflage sowohl in der Breite als auch in der Länge an die jeweiligen Bedürfnisse des Nutzers angepasst werden kann.According to one advantageous development, the foam part allows both a compression as well as an elongation in different directions, preferably in the length and / or in width, so that the thigh support both in the Width as well as in length to the respective needs of the user can be adjusted.

Wenn gemäß einer bevorzugten Ausgestaltung die Durchbrüche in Querrichtung gleichmäßig über das Schaumteil verteilt sind, kommt es zu keiner einseitigen Querschnittsschwächung, so dass ein gleichmäßiger Widerstand einen hohen Sitzkomfort gewährleistet.If according to a preferred embodiment, the openings in the transverse direction uniformly over the Foam part are distributed, there is no unilateral cross-sectional weakening, so that a uniform resistance ensures a high level of comfort.

Damit in jeder Stellung der Schenkelauflage eine kontinuierliche und faltenfreie Sitzoberfläche erhalten bleibt, gleitet nach einer vorteilhaften Ausgestaltung das Polstermaterial, mit dem das Schaumteil und das Sitzkissen bezogen sind, bei einer Verstellung der Schenkelauflage über das Schaumteil.In order to in each position of the thigh support a continuous and wrinkle-free seating surface maintains, slides according to an advantageous embodiment the cushioning material with which the foam part and the seat cushion are upholstered are, with an adjustment of the thigh support on the foam part.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung anhand der Zeichnungen. Es zeigen:Further Details, features and advantages of the invention will become apparent the following description with reference to the drawings. Show it:

1 eine perspektivische Ansicht des erfindungsgemäßen Fahrzeugsitzes, und 1 a perspective view of the vehicle seat according to the invention, and

2 eine Draufsicht des erfindungsgemäßen Fahrzeugsitzes. 2 a plan view of the vehicle seat according to the invention.

In den 1 und 2 ist ein erfindungsgemäßer Fahrzeugsitz 1 dargestellt. Der Fahrzeugsitz 1 besteht in bekannter Weise aus einer Rückenlehne 2, einem Sitzkissen 3 und einer verstellbaren Schenkelauflage 4. Die verstellbare Schenkelauflage 4 wird zumindest bereichsweise von einem Schaumteil gebildet, welches eine bestimmte Anzahl von Durchbrüchen 5 aufweist, die eine Verformung des Schaumteils erlauben. Die Durchbrüche 5 sind in Querrichtung so über das Schaumteil verteilt, so dass ein gleichmäßiger Widerstand des Schaumteils einen guten Sitzkomfort in den Fahrzeugsitzen 1 gewährleistet.In the 1 and 2 is a vehicle seat according to the invention 1 shown. The vehicle seat 1 consists in a known manner of a backrest 2 , a seat cushion 3 and an adjustable thigh pad 4 , The adjustable thigh support 4 is at least partially formed by a foam part, which has a certain number of breakthroughs 5 has, which allow deformation of the foam part. The breakthroughs 5 are distributed in the transverse direction over the foam part, so that a uniform resistance of the foam part a good seating comfort in the vehicle seats 1 guaranteed.

Die Durchbrüche 5 in dem Schaumteil sind derart angeordnet, dass das Schaumteil sowohl eine Stauchung als auch eine Dehnung in verschiedene Richtungen, vorzugsweise in der Länge und/oder in der Breite, ausführen kann. Dadurch ist eine Anpassung des Fahrzeugsitzes 1 an die individuellen Bedürfnisse möglich.The breakthroughs 5 in the foam part are arranged such that the foam part can perform both a compression and an elongation in different directions, preferably in the length and / or in the width. This is an adaptation of the vehicle seat 1 to the individual needs possible.

Damit bei einer Verstellung des Formteils eine kontinuierliche und faltenfreie Sitzoberfläche erhalten bleibt, gleitet das Polstermaterial, mit welchem das Sitzkissen 3 und die Schenkelauflage 4 bezogen sind, bei einer Verstellung der Schenkelauflage 4 über das Schaumteil.So that during an adjustment of the molding a continuous and wrinkle-free seating surface is maintained, the cushioning material slides, with which the seat cushion 3 and the thigh pad 4 are related to an adjustment of the thigh support 4 over the foam part.
