Description

The invention relates to a chair with a functional fitting, consisting of a chassis, which is preferably rotatably mounted on a rotary foot, a backrest part, a seat part and a leg rest, wherein the leg rest is hingedly connected to the seat part and the leg rest in the sitting position substantially below the seat part is folded and unfolded in the lying position in front of the seat part, that the seat part is extended by the leg rest.

In such armchairs usually have the seat part and the leg rest on a continuous padding. The adjustable fitting of the chair must be designed for an appealing design so that the upholstery is tightened with the leg rest folded out.

To achieve this, the legrest must be simultaneously pivoted and extended when unfolding.

From the DE202004011998U1 a chair has become known, in which this object is achieved by a two-part leg rest, wherein the parts of the leg rest during pivoting against each other are displaced.

However, it is disadvantageous that a drawstring is necessary for transferring the extended in the lying position parts of the swiveled leg rest in the retracted position in the sitting position.

Another disadvantage is that due to the short adjustment when pivoting from the sitting to the lying position and vice versa it comes to an undesirably jerky adjustment of the chair, whereby the comfort impression is narrowed.

Furthermore, the chair is complicated and therefore expensive to manufacture.

The invention is therefore based on the object to develop a chair of the generic type so that there is a more even, harmonious movement during pivoting of the chair and so the comfort impression is increased.

Also, the armchair should do without aids such as drawstrings or ropes and have an overall simple and inexpensive to implement construction.

Furthermore, the armchair should allow different designs in terms of leg rest design.

This object is achieved with the features listed in the protection claim 1.

Reference to an embodiment of the invention will be explained in more detail.

The accompanying drawings show in a schematic side view in

1 a chair according to the invention in sitting position,

2 Armchair according to 1 in lying position,

3 Armchair according to 1 with parallel to the seat part ( 3 ) arranged footrest,

4 Armchair according to 3 in lying position.

In the figures, an inventive armchair with functional fitting is shown.

The armchair consists of a body ( 1 ) with optionally armrests and / or a rotary foot ( 2 ), a seat part ( 3 ), a backrest part ( 4 ), a chassis ( 5 ) and a swing-out leg rest ( 6 ).

The leg rest ( 6 ) includes two pivotally mounted on the seat part ( 3 ) hinged, mutually parallel rails ( 6b ) each having a telescopic guide on which a telescoping leg support element ( 6a ) in the longitudinal direction of the rails ( 6b ) is arranged movable.

The seat part ( 3 ) is over between the seat part ( 3 ) and chassis ( 5 ) hinged front and rear handlebar levers ( 7a respectively 8th ) from a seated position displaced to the front edge of the chair ( 1 ) to a reclining position displaced to the trailing edge of the chair ( 2 ) and back to the seat position adjustable.

The front handlebar lever ( 7a ) has a strut ( 7b ), which, with the interposition of a control lever ( 10 ) hinged to the telescopic leg rest element ( 6a ) connected.

The displacement of the seat part ( 3 ) from its front seat position to the rear and vice versa, z. B. by shifting the weight of the seated person, on the one hand causes a pivoting of the handlebar lever ( 7a ) around the hinge point ( 9 ) with simultaneous pivoting of the strut ( 7b ), whereby the connection of the strut ( 7b ) with the telescopic leg rest element ( 6a ) via the control lever ( 10 ) an inevitable swinging or swinging the leg rest ( 6 ) synchronously with the movement of the seat part ( 3 ) is effected so that the leg rest ( 6 ) when moving the Seat part ( 3 ) to the rear from a substantially below the seat part ( 3 ) pivoted into a seat part ( 3 ) extending, approximately horizontal position is swung out.

At the same time, during the inward or outward swing of the leg rest ( 6 ) the leg rest element ( 6a ) along the on the seat part ( 3 ) hinged rails ( 6b ) telescopically in the longitudinal direction of the rails ( 6b ) retracted or extended.

For this purpose, according to the invention for defined control of the input and Ausschwenkbewegung the leg rest ( 6 ) on the one hand and the retraction and extension movement of the telescoping leg rest element ( 6a ) on the other hand provided that a guide lever ( 11 ) with its one end in the hinge point ( 12 ) with the seat part ( 3 ) and its other end in the hinge point ( 13 ) with the control lever ( 10 ) connected is.

Preferably, those on the seat part ( 3 ) hinged rails ( 6b ) and the guide levers ( 11 ) in a same horizontal axis on the seat part ( 3 ) hinged.

The leg rest element ( 6a ) is pivoted in, below the seat part ( 3 ) located position of the leg rest ( 6 ) so that the leg rest ( 6 ) has as short a length as possible ( 1 ).

When swung out, the seat part ( 3 ) lengthening, horizontal position of the leg rest ( 6 ) is the leg rest element ( 6a ) for increasing the length of the leg rest ( 6 ) extended ( 2 ).

According to the invention, it proves to be particularly advantageous if the rear handlebar lever ( 8th ) preferably has an approximately at least twice as long as the front handlebar lever ( 7a ), the front handlebar lever ( 7a ) in the sitting position at an angle of less than 20 degrees to the seat part ( 3 ), the front handlebar lever ( 7a ) and the strut ( 7b ) when adjusting the seat part ( 3 ) from the sitting to the lying position by an angle of more than 90 degrees in the hinge point ( 9 ) and the rear handlebar lever ( 8th ) when adjusting the seat part ( 3 ) from the sitting to the lying position by an angle of less than 60 degrees in the hinge point ( 21 ) is pivoted.

The interaction of all the above features ensures the desired smooth, harmonious movement, both in the adjustment of the sitting in the lying position and vice versa only a slight body weight displacement of the seated person is required.

At the same time, the chair according to the invention is characterized by a simple and cost-effective to be realized construction.

Another advantage of the chair according to the invention lies in the variability of the leg rest arrangement, it can, based on the seat part ( 3 ), Slopes of the leg rest ( 6 ) of 30-80 degrees or one parallel to the seat part ( 3 ), to the leg rest ( 6 ) connected footrest ( 6c ) ( 3 u. 4 ) and so the design of the chair can be significantly influenced.
