Definitions
- the invention relates to a chair fitting for motorized inclination adjustment of a backrest and for motorized folding and folding a two-part legrest.
- the fitting is completely preassembled at the factory between two side plates connected to crossbars, on each of which a side wall is to be fastened with an armrest, that seat fitting links are articulated directly or indirectly on each side plate, to which a mounting bracket for fastening a seat frame , over the length of which it extends approximately, is articulated, and the leg support parts are articulated directly or indirectly with a scissor arm as support arm, which each carry the leg supports on angle pieces, and a mounting plate for holding a backrest frame is articulated directly or indirectly on the mounting bracket and that a backrest cross member is arranged between the two-sided mounting plates and a seat cross member is arranged between the two-sided mounting brackets and between this and the backrest cross member Drive member of a backrest adjustment motor extends and that between the two scissors extends a scissor cross member, between which and one of the traverses extends a drive member of a leg rest drive motor, or that the drive member of the leg rest motor extends between a cross member and
- the basic structure which carries the entire handlebar and drive means and also the backrest, seat and support elements to be mounted on it, consists of the two outer side boards, on which the side parts are to be attached with the armrests, and the intermediate parts firmly connected to them traverses.
- the handlebars are made of flat iron, e.g. T. as far as a narrow free space is required, cranked, arranged close to the boards, and the mounting brackets and elbows extend with their mounting legs to accommodate the seat frame or the plate-shaped leg supports each inwards.
- the basic structure also includes the drives with the motors.
- the drive forces are transmitted directly or indirectly from the motors via cross bars to the fitting parts to be moved symmetrically on both sides.
- Spindle motors are preferably provided as the drive means and are very easy to link.
- the entire basic structure is accommodated on its side boards in load-bearing side walls that support the armrests and side upholstery.
- There is no separate base frame for the furniture since all other furniture parts, the backrest, the seat and the leg support plates are held and fastened to the base structure.
- the transverse stability of the furniture results not only from the crossbeams through the cross bars and the furniture parts screwed on at an angle, which extend from side fittings to side fittings.
- Legrest fitting link connected and is adjusted together with this by the legrest adjustment drive.
- the seat is thereby coupled to the leg supports so that the seat links are approximately parallel when the supports are raised and are inclined forward when the supports are set, so that in this position the seat is lowered further at the front and is essentially at a constant height when being adjusted at the rear , Since the backrest is articulated on the seat mounting bracket in the rear area and the backrest adjustment drive is located between the seat and the backrest, the respective backrest position relative to the seat remains unaffected by the legrest adjustment, the seat and backrest are displaced together approximately horizontally.
- the mounting angle of the seat and the mounting plate of the back are articulated to one another on a mounting angle extension which is arranged approximately at the middle height of the seat and the back between them near the back cushion.
- the two cushions are close together in the sitting position and only move about an amount in the lying position that corresponds to half the seat cushion height.
- the joints and mounting parts, which are closely attached to the side of the upholstery, are offset sufficiently downwards in the gap so that they do not interfere.
- the mounting bracket and the mounting plate are each connected to a backrest scissor link, the links of which are designed and articulated in such a way that the backrest cushion and the seat cushion always touch in the upper area during the backrest adjustment and there is no gap between them.
- the seat mounting bracket has a downward extension for the articulation of the lower seat-side handlebar.
- the upper scissor arm on the seat side is articulated close to the lower rear seat end above the other scissor arm.
- the backrest scissor links are arranged in a multi-part scissors, whereby advantageous adaptations of the movements different upholstery are possible. This makes it particularly advantageously possible to touch the backrest and seat cushions in the entire adjustment range of the backrest almost without sliding the cushions onto one another, thus avoiding increased wear on the contact points.
- the leg supports are adjusted via the movement of the seat frame, the motor being fastened to a traverse and its adjusting spindle moving the seat frame back and forth via a pivoting lever which engages in the rear seat frame area.
- the coupling of the seat frame in the front area with the support bracket links enables the leg supports to be adjusted.
- the cross member between the leg support links is omitted and allows greater freedom from this area.

- Support fitting link in an enlarged section of area X according to FIG. 9;
- FIG. 11 shows a view A - A according to FIG. 10 in section
- FIG. 12 shows a top view of the fitting from FIG. 9.
- FIG. 1 shows a side view of an armchair in the reclining position, one side wall of which has been removed and a complete assembly on the side wall 42 at the rear of the picture.
- is screwed assembly which consists of symmetrical, congruent fitting assemblies in the picture, each of which is held on a side plate 4, of which the one lying in the picture behind is screwed to the side wall 42. Since the side fitting assemblies are symmetrical, the same reference symbols are always used for parts that belong together.
- Extending between the side plates 4, as shown in FIG. 2, are stable cross members 40, 41, which are tubularly welded into suitable plate recesses or otherwise detachably or firmly connected.
- a seat fitting link 24, 34A is articulated, on each of which a mounting bracket 20 is articulated on the other side, to the inwardly directed leg of which a seat frame of a seat is screwed.
- the mounting bracket 20 is connected to the mirror image with a stable seat cross member 22.
- a mounting bracket extension 20A extends from the mounting bracket 20 upwards to approximately half the height of the seat cushion, to which a fitting plate as a mounting plate 10 of the backrest 1 or a backrest frame is hinged, to which it is laterally screwed several times.
- Said back joint 23 on the mounting plate 10 lies a little way below the surface of the back cushion.
- a backrest cross member 12 is arranged from mounting plate 10 to mounting plate.
- a backrest adjustment motor 11 is articulated on this backrest cross member 12 and on the seat cross member 22 with a drive member 13, preferably a spindle.
- the seat 2 is pressed forward on the seat mounting bracket 20, being supported on the short front link 34A.
- the backrest 1 is pivoted upward with the mounting plate 10, as shown in FIGS. 3 and 4 in different phases.
- the front seat link 34A continues beyond its plate joint in the seat-side upper scissor arm 34 of the support fitting link and is adjusted together with its drive.
- the backrest 1 In the rest position shown in FIG. 1, the backrest 1 is inclined slightly rising towards the rear and the seat cushion 2 is inclined slightly towards the back and is shifted a hand wide in the direction of the backrest 1, but there is a gap of a few centimeters between the two pads.
- the surface of two leg supports 3A, 3B extend at a somewhat lower level to each other, which are articulated on both sides with angle pieces 30A, 3OB, each screwed to support fitting links 34 - 38, which consist of an auxiliary link 38 and scissors 34 - 37 , which is articulated on the other side plate 4.
- the scissors 34-38 have relatively long levers which extend approximately from the seat to the floor when the scissor joint passes approximately its lowest point when pivoting, as can be deduced from FIGS. 3 and 5, which shows an intermediate state or the pivoted-in state of the leg supports 3A , 3B show.
- the front leg support 3B is pivoted in vertically and extends at a short distance above to below the frame of the seat 2 and below to a few centimeters above the floor. In the transverse direction, as shown in FIG. 2, it closes the entire front area between the armchair side walls 42 with a small lateral distance.
- the rear leg support 3A is folded in approximately parallel to the front, spaced from it, so that there is also space for upholstery. According to FIG. 2, the lateral extension of the rear leg support 3A is somewhat smaller than that of the front, so that there is space on the side for the scissors and the flange of the angle pieces 30A, 30B. So that the rear leg support 3A pivots from the vertical position into the approximately horizontal support position according to FIG. 1 when the scissors are actuated, the downward leg of the angle piece 30A is on the one hand on a front scissor arm 36 and on the other hand with an auxiliary link 38 on a rear Scissor arm 35 articulated.
- the visibility conditions of the support fitting links 34 - 38 in FIG. 1 correspond to a view I - I from the center in FIG. 2 of the fitting shown above.
- the rear scissor links 34, 35 are arranged one above the other close to the side plate 4 and the front scissor links 36, 37 to the right and left of these. This narrow design of the scissors arrangement prevents the occurrence of torsional moments.
- the outer front scissor arm 37 is approximately twice as wide as the rest. As a result, it has a much higher section modulus and in no travel position does such a gap form between the front scissor arms into which a finger fits that could be squeezed as a result.
- the rear scissor arms 34, 35 are also in their narrowest position, which is shown in FIG. 1, so far apart that fingers fit between them and there is therefore no risk of being crushed.
- FIGS. 6-8 show a second embodiment of the backrest linkage, which takes place via scissors gears 14-17.
- the views FIGS. 6 and 7 are from section VI - VI; the side boards and the rear seat link are not shown there for better clarity.
- FIG. 6 shows the backrest 1 in an upright position and FIG. 7 in a completely lowered position.
- the upholstery of the backrest 1 and the seat 2 touch in all positions; there is no annoying gap in which loose cushions or ends of clothes can be pulled or pinched.
- the seat fitting 20 has a downwardly directed mounting bracket extension 2OB, on which the seat-side scissor arms 14, 15 are articulated, offset one above the other.
- the backrest-side scissor arms 16, 17 are directed upwards on the one hand and spaced one above the other and articulated one behind the other on a mounting plate 10B and connected to the backrest 1 on its frame.
- the backrest cross member 2OB to which the backrest adjustment motor 11 is connected is cranked.
- the backrest cross member 2OB extends between mounting plates 10B. These, as well as all the backrest drive elements and the backrest scissor drive, are in all backrest positions under the seat and backrest upholstery, and these upholstery extend laterally to close to the side walls of the armchair.
- FIG. 9 shows an armchair in a further exemplary embodiment of the backrest scissor links 14 - 17 and the leg support drive 31, 33.
- the backrest scissor links 14, 15, 16, 17 together with other backrest scissor links 15A, 16A form a multistage scissors in the manner of a Nuremberg pair of scissors.
- the backrest 1 is shown in an upright position.
- the seat-side scissor arm 15 is pivotally connected to the back-side scissor arm 16 and the scissor arm 14 via two further scissor arms 16A and 15A to the back-side scissor arm 17.
- the backrest-side scissor arm 16 is spaced apart from the back-side scissor arm 17. This results in an advantageous possibility of adapting the movement of the backrests to different structures, so that the upholstery of the backrest 1 and the seat 2 is again also advantageous in every position Touch in such a way that there is no gap.
- the motor 31 of the leg support adjustment drive is articulated on the cross member 40, its support adjustment spindle 33 is pivotable on a cross member 22A hinged.
- the cross member 22A lies between two pivot levers 43 and is connected to these.
- the pivot levers 43 are pivotally mounted on the side boards 4 and are pivotally connected to the mounting brackets 20 at their upper ends.
- the support fitting links 34 are coupled in a coupled manner and in doing so extend the leg supports 3A, 3B.
- the leg supports 3A, 3B are thus adjusted indirectly via the movement of the mounting bracket 20.
- the advantage here is that the cross member 32 is omitted and more space is created for the retraction of the leg supports 3a, 3B.
- FIG. 10 shows an enlargement of the area X according to FIG. 9, the coupling of the mounting bracket 20 to the bracket fitting link 34 via a bolt 44.
- the bracket fitting link 34 has an angled extension for this purpose with an elongated hole 34B which is connected to the bolt 44 and thus to the Mounting bracket 20 is connected. It is particularly advantageous to use an elongated hole, since significantly lower drive forces are required for adjusting the leg supports.
- FIG. 11 shows a view of the section A - A of FIG. 10.
- the elongated hole 34B is provided with a low-friction design, for example a bushing 34C.
- the bolt 44 which also has a bushing 34D, is guided with low friction.
- the material of the bushings 34C, 34D is preferably plastic.
- FIG. 12 shows a top view of the fitting according to FIG. 9.
- a plurality of centering bolts 18 and also round screw holes 19 are introduced therein.
- the seat frame can thus be inserted with the centering bolts (18) into suitable centering holes and held in position when the fixing screws are screwed in through the screw holes 19.
- the backrest frame and the side walls are pre-drilled with templates or fitted with screw bolts or bushings, so that the backrest and the side boards are easily screwed into position there.
- the mounting brackets and / or the side plates 4 are preferably introduced into the centering bolts 18, as a result of which these are received in suitable bores and are to be screwed together in a centered position.
