Description

The invention relates to a chair with a Hebelverstellgetriebe for a swing-out footrest, with a body, a chassis, which is optionally rotatably mounted on a swivel base, a back, a seat part and a fold-out footrest, wherein the seating between a sitting and lying position is pivoted what the seat part relative to the chassis is displaced to the rear and the footrest is coupled to the seat part, that it is pivoted when moving the rear seat part, the footrest folded in the sitting position substantially below the seat part and in the lying position so before the seat part is folded out so that the seat part is extended by the footrest.

Such chairs usually have a seat part and footrest extending, continuous padding. Here, the adjustment fitting of the chair for an attractive design must be designed so that the upholstery is taut with the footrest extended.

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

From the pamphlets DE 10 2012 204 670 A1 and DE 20 2004 011 998 U1 Seating furniture have 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 belt drive / tension band system is necessary for transferring the extended in the lying position parts of the swiveled leg rest in the retracted position in the seat position and relatively expensive and susceptible to wear, telescopic guide rails are required to move the parts of the leg rest.

A further disadvantage is that the swung-out leg rest does not assume a stable position, so that with only slight movements of the user's lower leg, the leg rest is moved in the horizontal and in the vertical direction. However, this is not desirable because the leg rest should only be adjusted when the total body weight is shifted.

From the DE 20 2012 000 227 U1 and the DE 20 2012 102 378 U1 Seating are known in which the leg rest is formed by a one-piece footboard, which is arranged in the sitting position at an acute angle to the seat part. The disadvantage here is that voluminous Scherengelenkketten are required for pivoting the leg rest, which are located in the lateral viewing area far below the seat part, so that at least for modern seating with swivel base and open side armrests, this solution is not suitable because the aesthetics of the chair disturbed too much would.

From the DE 201 04 538 U1 is a chair known in which the scissor hinge chains used for pivoting the leg rest are arranged very space saving, but this construction is not suitable for a chair with seat part and footrest extending, continuous padding, as guided due to the sweeping movement curve of the scissors articulated chains Leg rest would result in overstretching of a continuous padding during pivoting of the leg rest. A further disadvantage is that a total of six adjustment lever are required for the adjustment of the front portion of the seat part and for the adjustment of the footrest, whereby the manufacturing cost is relatively large.

Based on the described prior art, the present invention seeks to provide a Hebelverstellgetriebe for pivoting a footrest for a chair of the type mentioned, which is particularly space-saving, doing without guide rails and its realization with design and manufacturing technology simple means is possible ,

The above object is achieved by a chair with the features listed in claim 1.

By the features according to the invention, it is possible to provide a Hebelverstellgetriebe for pivoting an obliquely arranged below the seat part footrest, which claimed according to the invention a space of about three to four lever widths below the seat part in the sitting position of the chair and only has swivel joints instead of guide rails.

Furthermore, a continuous upholstery extending over the seat part and footrest without overstretching during the pivoting of the footrest from the sitting to the lying position is tightened and the swung-out leg rest assumes a stable, fixed position.

The invention allows for various embodiments. To further clarify its basic principle, three of them are shown in the drawing and will be described below.

This shows in

1 an inventive seating in sitting position of the chair;

2 a chair according to 1 lying position of the chair;

3a a detailed view according 1 ;

3b a detailed view according 3a with partially pivoted footrest;

4 a detailed view according 1 using an intermediate piece ( 6c );

5 a detailed view according 4 lying position of the chair;

7 a chair according to 6 lying position of the chair;

8a a detailed view according 6 with partially pivoted footrest;

8b a detailed view according 8a , further pivoted.

The 1 to 3a , b show a basic form of the seat according to the invention.

An inventive seating 1 consists of a body and / or a swivel base 2 a chassis 5 , A back part, not shown in the figures, a seat part 3 and a fold-out footrest 6 , where the seating furniture 1 between an in 1 shown sitting position and one in 2 shown lying position is pivotable. For pivoting the seat 1 is the seat part 3 opposite the chassis 5 displaceable. The footrest 6 is like that with the seat part 3 coupled, that this when moving the seat part 3 , z. B. by shifting the weight of the seated person, is pivoted.

The seat part 3 and the footrest 6 have a continuous padding 4 on.

The footrest 6 is pivoted when unfolding and extended so that the padding 4 with unfolded footrest 6 is streamlined.

The footrest 6 is about at least one Hebelverstellgetriebe 9 , in particular in the form of four, in operative connection, arranged in pairs, articulated levers 13 . 14 . 15 . 16 , to the seat part 3 or chassis 5 connected.

The seat part 3 is over between seat part 3 and chassis 5 hinged front and rear handlebar levers 7 respectively 8th from one to the front edge of the chair 1 relocated and in the 1 and 4 shown sitting position in a to the rear edge of the chair 1 relocated and into the 2 and 5 shown lying position adjustable.

The footrest 6 is preferably by a one-piece footboard 6b formed, which has a greater width than the distance of the toggle lever pairs and a length which, in the sitting position of the chair 1 , more than half, preferably more than two-thirds of the distance from the seat part leading edge 24 to the riot level of the chair 1 matches, with the footrest 6 such with the adjustment of the seat part 3 coupled is that these when moving the seat part 3 is pivoted, with the footrest 6 in pivoted position at least partially below the lowest point of the Hebelverstellgetriebes 9 and substantially obliquely below the seat part 3 is arranged and with one of the front edge of the seat part 3 vertical plane enclosed an angle of 10 ° to 90 °, and in the lying position, the footrest 6 so in front of the seat part 3 swung out, that is the seat part 3 through the footrest 6 is extended.

The lever adjustment gear 9 is according to the invention with a first end of a first articulated lever 13 on the chassis 5 hinged and the toggle lever 13 about his articulation point 10 to the chassis 5 extended and forms the front handlebar lever 7 of the seat part 3 with a first end of a second articulated lever 14 on the chassis 5 or on the seat part 3 hinged, the first and the second toggle lever 13 . 14 with their free ends on a third toggle lever 15 hinged, the third toggle lever 15 with its free end to a Fußteilbeschlag 6a the footrest 6 hinged, and one in a middle area of the first 13 or the second articulated lever 14 articulated fourth articulated lever 16 with its free end on the foot fitting ( 6a ) of the footrest 6 hinged.

The displacement of the seat part 3 on the one hand causes a pivoting of the front handlebar lever 7 around the hinge point 10 with simultaneous pivoting of the first articulated lever 13 , The one with the first toggle lever 13 operatively connected further transmission elements 10 . 11 . 12 . 14 . 15 . 16 . 19 . 20 . 25 . 26 ensure by their arrangement an inevitable Einschwenkung or swinging the footrest 6 synchronous with movement of the seat part 3 ,

In a particularly preferred arrangement according to the invention of the four joint levers operatively connected to one another 13 . 14 . 15 . 16 is the on the chassis 5 hinged first toggle lever 13 with its free end at the first end of the third articulated lever 15 hinged, the second end of the foot fitting 6a the footrest 6 hinged, the second toggle lever 14 hinged to the chassis and with its other end on the third toggle 15 articulated, and a in a central region of the second articulated lever 14 articulated fourth articulated lever 16 with its other end on the foot fitting 6a the footrest 6 hinged, wherein the longitudinal axes of the third and fourth articulated lever 15 . 16 in sitting position of the chair 1 are oriented substantially horizontally.

Here is the articulation point 11 of the second articulated lever 14 on the chassis 5 closer to the front edge of the chair 1 and, based on the floor, preferably positioned by about a lever width higher than the articulation point 10 of the first articulated lever 13 on the chassis 5 while in seating position of the chair 1 the articulation point 11 of the second articulated lever 14 on the chassis 5 closer to the rear edge of the chair 1 is positioned as a pivot point 12 the front handlebar lever 7 on the seat part 3 ,

In seating position of the chair 1 is a point of articulation 25 of the fourth articulated lever 16 at the foot fitting 6a the footrest 6 closer to the front edge of the chair 1 as a point of articulation 26 of the third articulated lever 15 at the foot fitting 6a the footrest 6 positioned.

This inventive lever arrangement of Hebelverstellgetriebes 9 in which the individual toggle lever 13 . 14 . 15 . 16 do not cross each other in the form of an articulated scissors, in conjunction with the inventive arrangement of the articulation points 10 . 11 . 12 . 25 . 26 guaranteed unlike the one from the publication DE 201 04 538 U1 Scherengelenkketten revealed that the footrest 6 during pivoting from the sitting to the lying position of a "flat" movement curve near the seat part 3 follows, leaving at least one of the pivot points 25 of the third and / or fourth articulated lever 15 . 16 at the foot fitting 6a the footrest 6 opposite one, in the seating position of the chair 1 , from this point of articulation 25 clamped horizontal plane during the entire pivoting of the footrest 6 rising from the sitting in the reclining position.

This ensures that during the pivoting of the footrest 6 a over seat part 3 and footrest 6 extending, continuous padding 4 without overstretching the padding 4 is rolled off.

The 3a and 3b show that the seating furniture according to the invention 1 during a first phase of pivoting the footrest 6 from the sitting position to the lying position, the distance between the seat part leading edge which is decisive for the unwinding of the upholstery 24 and footboard leading edge 6b only increased by about 10 mm, with the out of the DE 201 04 538 U1 known seating, the distance has already increased by about 80 mm with the same footrest position.

According favored, the slight increase in the distance between the seat part leading edge 24 and footboard leading edge 6b during the first pivoting phase of the footrest 6 in that, in the seating position of the chair 1 , the longitudinal axes of the first and second articulated levers 13 . 14 , from the seat part 3 looking towards the floor, diverge while taking an angle 23 of at least 3 °, preferably about 12 ° -14 °, and that of the longitudinal axes of the first and second articulated levers 13 . 14 included angles 23 during the pivoting of the chair 1 from the sitting to the lying position continuously reduced to about 0 ° or beyond, leaving the seat in the seating position 1 apart longitudinal axes of the first and second articulated levers 13 . 14 in the lying position of the chair 1 to run towards each other.

Furthermore, the small increase in the distance between the seat part leading edge 24 and footboard leading edge 6b during the first pivoting phase of the footrest 6 thereby favors that, in sitting position of the chair 1 , the longitudinal axis of the second articulated lever 14 is predominantly vertically aligned with one of the front edge of the seat part 3 vertical plane spanned an angle <45 °.

During a later pivoting phase of the footrest 6 in the direction of lying position of the chair 1 there is a requirement for a possible extended orientation of the Hebelverstellgetriebes 9 for sufficient tightening of the continuous upholstery 4 lying position of the chair 1 ,

According to the invention, this in turn is advantageous to that of the longitudinal axes of the first and second articulated levers 13 . 14 trapped, during the pivoting of the chair 1 from the sitting to the lying position continuously decreasing angle 23 and a bent course of the third toggle lever 15 in the area of its articulation point 19 with the second toggle lever 14 in the direction of its articulation point 20 with the first toggle lever 13 so that especially in a final pivoting phase of the footrest 6 an extension of the Hebelverstellgetriebes 9 takes place, at which, in lying position of the chair 1 , the longitudinal axes of the second articulated lever 14 and fourth articulated lever 16 at an angle 22 of more than 140 degrees to each other.

In terms of the least possible space occupied Leververstellgetriebes 9 from according to the invention about three to four lever widths below the seat part 3 in sitting position of seating furniture 1 It is advantageous according to the invention, when the third and fourth articulated levers 15 . 16 have a greater length than at least one of the first and second toggle levers 13 . 14 ,

In addition to the requirement of the least possible space occupied at the same time sufficient travel of the Hebelverstellgetriebes 9 for streamlining the continuous upholstery 4 in the swung-out position of the footrest 6 be guaranteed.

For this purpose, the invention provides that in the sitting position of the chair 1 the front handlebar lever 7 at an acute angle to the seat part 3 less than 10 degrees and the longitudinal axes of the front handlebar lever 7 and first toggle 13 at an angle 21 of more than 135 degrees to each other.

This in turn allows the front handlebar lever 7 and the first toggle lever 13 when adjusting the seat part 3 from the sitting position to the lying position around its point of articulation 10 on the chassis 5 be pivoted by more than 110 degrees, creating a sufficient travel of the Hebelverstellgetriebes 9 is made available.

Advantageously in accordance with the invention, the adjustment of the front region of the seat part ( 3 ) and the adjustment of the footrest ( 6 ) over a total of four joint levers ( 13 . 14 . 15 . 16 ), whereby the articulated levers ( 13 . 14 . 15 . 16 ) Do not cross each other in the form of a hinged scissors, the goal of a seating furniture with only three to four lever widths below the seat part space consuming Leververstellgetriebe for pivoting an obliquely arranged below the seat part footrest available, the Hebelverstellgetriebe exclusively swivel joints instead Having guide rails, wherein a extending over the seat part and footrest, continuous upholstery without overstretching during the pivoting of the footrest is tightened from the sitting to the lying position was thus achieved.

Furthermore, the seating according to the invention is characterized by a structurally simple construction, since only four pivotally operable joint levers are needed for adjusting the front portion of the seat part and for adjusting the footrest, at the same time a large pivoting angle of the footrest of about 145 ° 165 ° is provided during the pivoting of the chair from the sitting to the lying position.

The 4 and 5 show a second advantageous embodiment of the seat according to the invention 1 , This embodiment is particularly based on the features of claims 20 to 22.

In contrast to the first embodiment, which is suitable for seating 1 in which the footrest 6 in pivoted position obliquely below the seat part 3 is arranged and with one of the front edge of the seat part 3 spanned vertical plane encloses an angle of about 10 ° to 70 °, this second embodiment is for such seating 1 suitable in which the footrest 6 with the vertical plane encloses an angle of about 70 ° to 90 °, so that the footrest 6 almost parallel to the seat part 3 is arranged.

Here, in contrast to the first embodiment, the Hebelverstellgetriebe 9 with at least one of the third and / or fourth toggle lever 15 . 16 at one of the Fußteilbeschlag 6a the footrest 6 upstream and articulated with this intermediate piece 6c hinged, and the footrest 6 via a connecting lever 18 with the Hebelverstellgetriebe 9 and the intermediate piece 6c coupled.

According to the invention, the third and the fourth articulated levers are preferred 15 . 16 at a distance from one another at a Fußteilbeschlag 6a the footrest 6 upstream and articulated with this intermediate piece 6c hinged, with one of the toggle lever 16 over the range of its point of articulation 17 at the intermediate piece 6c is extended and at its free end at the first end of a connecting lever 18 hinged, the second end hinged to the Fußteilbeschlag 6a the footrest 6 connected.

The displacement of the seat part 3 on the one hand causes a pivoting of the intermediate piece 6c , During the pivoting of the intermediate piece 6c becomes the toggle lever at the same time 16 around its point of articulation 17 at the intermediate piece 6c pivoted, causing the footrest 6 opposite the intermediate piece 6c is pivoted.

Advantageously according to the invention during the pivoting of the seat 1 from the sitting to the lying position, the intermediate piece 6c pivoted about 100 ° and at the same time the Fußteilbeschlag 6a the footrest 6 opposite the intermediate piece 6c pivoted about 65 °.

The aforementioned features allow a greater tilt angle of the footrest 6 in comparison to the first embodiment.

Due to the inventive design space-saving design of Hebelverstellgetriebes 9 is one on the footrest 6 attached footboard 6b in sitting position of the chair 1 for the most part Part below the lowest point of the Hebelverstellgetriebes 9 and with a short distance to the seat part 3 arranged, creating a beneficial slim design of the chair 1 is possible.

The 6 to 8a , b show a third embodiment of the seat according to the invention 1 ,

In this embodiment, which is based in particular on the features of claims 26 to 29, in contrast to the first two embodiments, the seat part 3 and the footrest 6 no continuous padding on.

The footrest 6 and / or the seat part 3 have in the side view respectively an approximately L-shaped appearance and are in the seating position of the chair 1 so arranged to each other that the footrest 6 almost parallel to the seat part 3 runs and the respective short legs of the L-shaped parts at their free ends in such a collision with a slight gap formation that seat part 3 and footrest 6 together have an approximately U-shaped appearance.

From the publication DE 201 04 538 U1 is such a chair known, which is disadvantageous in that the footrest is relatively short and in swung-Postion of the footrest a large gap between the seat part and footrest is present, whereby the comfort impression of the user is reduced due to the non-continuous leg rest.

It is desirable that in a "floor-free" seating of the type mentioned, the footrest is pivoted with minimal gap formation to the seat part in the lying position and thereby has a much greater length compared to the known from the prior art footrest.

To solve this problem, an inventive seating furniture 1 in principle, the known from the above first embodiment of the invention adjustment mechanism 7 . 8th . 9 on, with the inventive advantage that during a first phase of the pivoting of the footrest 6 from the sitting position to the lying position, the front edge of the footrest 6 a "flat" movement curve near the seat part leading edge 24 follows, in this third embodiment can be used to that in the swung-out position of the footrest 6 a nearly continuous leg rest due to only a small gap formation between the seat part 3 and footrest 6 arises.

The 8a and 8b show that the seating furniture according to the invention 1 the front edge of the footrest 6 during the first half of the pivoting phase of the chair 1 from the sitting position to the lying position of a movement curve near the seat part leading edge 24 with a distance of only a few millimeters follows, while in the case of the DE 201 04 538 U1 known seating with scissor link chains the distance at the same footrest position ( 8b ) has already increased by about 80 mm.

This has the consequence that the footrest at the out of the DE 201 04 538 U1 known seating must be relatively short, about 260 mm, so as not to touch the ground during pivoting. In order nevertheless to achieve a sufficient length of stay, the footrest must be relatively far extended in the lying position, which in turn has a large gap formation between the seat part and footrest result.

When seating furniture according to the invention 1 can the footboard 6b have a length of 350 mm, so that the Hebelverstellgetriebe 9 can be controlled so that the gap formation between seat part 3 and footrest 6 lying position of the chair 1 about 90 mm compared to that from the DE 201 04 538 U1 known seating can be reduced without the deck length is shortened in comparison.

Supportive according to the invention for the control of the Hebelverstellgetriebes 9 to achieve the smallest possible gap formation between the seat part 3 and footrest 6 is that the articulation point 25 of the fourth articulated lever 16 at the foot fitting 6a the footrest 6 at a distance of about one to two lever widths from the back of the shorter leg of the Fußteilbeschlag 6a the footrest 6 attached footboard 6b is positioned and that the articulation point 26 of the third articulated lever 15 at the foot fitting 6a the footrest 6 closer to the back of the foot fitting 6a the footrest 6 attached footboard 6b , preferably at about one to two lever widths, is positioned as the hinge point 25 of the fourth articulated lever 16 at the foot fitting 6a the footrest 6 ,

The pivoting of the front handlebar lever 7 by more than 110 degrees, preferably by about 130 degrees, allows the longitudinal axis of the second articulated lever 14 lying position of the chair 1 , viewed from the rear edge of the chair toward the front edge of the chair, opposite one of the pivot point 11 of the second toggle lever 14 on the chassis 5 spanned horizontal plane is rising and that the longitudinal axis of the first articulated lever 13 , lying position of the chair 1 , Almost horizontally aligned, causing the pivoting of the footrest 6 in an area above the seat part leading edge 24 is favored.

The aim of providing a floor-free seating furniture, which has a nearly continuous leg rest in a pivoted position due to only a small gap formation between the seat part and footrest and thereby a much greater length of the footrest compared to the known from the prior art footrest, was thus achieved.
