    seating
    The invention relates to a chair, consisting of a body with side cheeks, held between the side bolsters seat part, a footrest, a back and a fitting system for adjusting the seat part, the back part and for moving the footrest from a pivoted non-use position into a pivoted-use position the fitting system consists of a chassis with attached to the side walls of the seat fitting plates, which are connected by trusses together to form a rigid unit, and hinged to the fitting plates articulated scissors, which hold the footrest, being hinged to the fitting plates on lever levers supporting the Hold seat part and by means of which the seat part from a to the front edge of
    Seating displaced basic position is adjustable in a displaced to the trailing edge of the chair rest position, wherein the articulated scissors are switched by the displacement of the seat part and swing out, each articulated scissors consists of scissor levers which are hinged together, the free ends of a first and second scissor lever each on a fitting plate and the free ends of a third and fourth lever are hinged to a footrest bearing coupling, a first lever is extended via the pivot point on the fitting plate and hinged to the serving as a lever extension in each case the first, front support member of the seat part , Wherein, in each case an adjusting lever is articulated at the rear end of each fitting plate, on which the second rear support part of the seat part is articulated.
    Such a chair is known from DE 101 23 308 A1.
    The functional fitting for this known seating is extremely simple and very functional. Therefore, the furniture equipped with this fitting is to provide cost-effective.
    From DE 200 00 926.5 U 1 a chair with a similar fitting training is known. Here, however, a motor-linear acting actuator is provided by means of which the adjustment of the fitting and thus the different position of the chair can be realized. In addition, the chair described in this document is still equipped with a stand-up, which is also actuated by means of the actuator.
    Also this armchair is extremely functional and has proven itself in practice.
    A disadvantage, however, is seen in the fact that in this training two rotary braces are required, which are coupled to the actuator and by means of which the corresponding functions of
    Armchairs can be performed. Such rotary traverses are more expensive to manufacture than rigid trusses, which are used only to stabilize the fitting system. Due to the cost pressure, there is a need to provide seating with similar functions available, which are simpler in spite of an electric motor linear drive.
    To solve this problem, the invention proposes that the two rear support members are interconnected by a rigid cross member, projects from a support lever down to the riot plane of the chair, that on the support lever, the motor housing of an electromotive linear actuator is hinged, of which Motor housing protrudes a spindle-like part, in the direction approximately parallel to the seat below the seat of the seat part to the front edge of the chair out that arranged on the spindle-like part a driver in the manner of a spindle nut and adjustable by the spindle of the spindle-like part along the same the driver is hinged to a connected to a pedestal of the chair lever that is arranged in the basic position of the seat of the driver approximately in the central region of the spindle-like part, said means of the actuator upon rotation of the spindle-like part, the seat part of the Gr and position in the rest position is adjustable while the footrest is swinging, in which case the driver retains its position relative to the body of the chair and the actuator including spindle-like part is moved to the rear edge of the body in a first position.
    With this design, it is possible, on the one hand to use an electromotive linear actuator to perform the function of the chair, on the other hand, can be dispensed with the use of so-called rotary traverses. Instead, only a rigid cross member as an abutment is required, which can be made much cheaper available, as is the case with rotary traverses. The installation of such hardware systems in the corresponding
    Seating furniture is simplified because the installation situation is easier with rigid trusses than with rotary trusses.
    Conventionally, the electromotive actuator is operable by a wired or wireless remote control by the user. A significant feature of the invention is that the rigid cross member can be used as a fixed abutment for the actuator, which is suitably fixed to the crossbar, so that it is preferably located centrally between the fitting plates and allows a symmetrical application of force. The driver, which is designed in the manner of a spindle nut, is supported on an abutment, which is formed by a connected to the pedestal of the chair lever. By actuating the actuator, it is thus possible to move the entire seat part from the basic position to the rest position and back to the normal position, the driver constantly retains its position and the entire seat part by means of the spindle-like part of the actuator
    Actuator and traverse is adjusted relative to the body of the chair.
    In a manner known per se, it is provided that the extension of the first lever is arranged with the articulation point on the first, front support member in the basic position between the front edge of the chair and the pivot point of the second lever and in the rest position between the pivot point of the second lever and the trailing edge of the chair.
    Preferably, it is also provided that the first lever rests in the rest position, that is, when the footrest pivoted out, against a limit stop of the fitting plate.
    Also in a conventional manner it is provided that at the second, rear support member each have a pivot lever to which the back of the chair is attached, and a toggle for pivoting the back part or the pivot lever is articulated, the toggle preferably against the force of a tension spring is actuated, which is clamped between the pivot lever and a lever of the toggle lever.
    It is preferably provided that by means of the actuator in the spindle of the spindle-like part, the back part is adjustable from a steeper basic position into a flat-inclined rest position, whereby also the driver retains its position relative to the body of the chair and the actuator including spindle-like part to the rear edge of the Body is adjusted to a second position.
    In order to equip the seating additionally with a Aufstehhilfsfunktion, it is provided that the base of the chair consists of a Fußfußteil as a coupling, are hinged on the one hand in pairs four-bar linkages, on the other hand hinged to the fitting plates as coupling, so that the seating furniture in total from the normal position is adjustable in a raised slightly sloping forward sloping Aufstehhilfsposition that the joints of a toggle lever pair are formed on the fitting plates by a Drehtraverse on which one ends of the toggle lever of the toggle pair are fixed, which protrudes from the Drehtraverse the lever, which on the driver is hinged to the actuator, that the pivoting of the lever is limited so that it is pivotable from the stand-up position to the normal position, and that the driver by means of the actuator from the basic position in a stand-up position corresponding position along the spin delartigen part in the direction of the actuator is optionally adjustable to the stop on the housing.
    When operating the Aufstehhilfsfunktion the seating is first to move to the normal position in which the seat part and the back part occupy the basic position. If then the actuator is not operated in the direction in which the adjustment of the seat part and the back part can be done, but in the opposite direction, the driver moves on the spindle-like element in the direction of the motor or the motor housing, said by the rotary beam acted on the appropriate lever of the four-bar linkage, so that they sit up and lift the entire armchair and adjust to a slightly inclined forward sloping position. This position corresponds to the stand-up auxiliary position, wherein the travel limit occurs in that the driver starts to the motor housing or the like frame-fixed parts. During the return movement into the basic position, the driver runs along the spindle-like element approximately to its middle. In this position, the four-bar chain and the operable by the crossbar lever has reached its final position beyond which these parts are not movable. Upon further actuation of the drive in the same direction then the spindle-like part is moved in the quasi-fixed driver and thereby adjusted the seating from the basic position to the rest position and the backrest in the comfort position.
    The construction is significantly simplified compared to the equivalent state of the art and therefore more cost-effective to make available.
    An embodiment of the invention is illustrated in the drawing and described in more detail below. It shows:
    Figure 1, the seating in the basic position, partially cut;
    Figure 2, the seating in a first
    Rest position;
    Figure 3, the chair in the rest position with back flat inclined backrest;
    Figure 4 fitting parts of the chair in the
    Position seen in Figure 3;
    Figure 5 fitting parts of the chair in the
    Aufstehhilfsposition.
    In the drawing, a chair is shown, which has a body with side cheeks 1, a held between the side walls seat part 4, a footrest 5 and a back part 6. Furthermore, a fitting system for adjusting the seat part 4, the back part 6 and for displacing the footrest 5 from a pivoted non-use position shown in Figure 1 in a pivoted-use position shown in Figure 2 is provided. The fitting system consists of a chassis with on the side walls 1 of the chair opposite fitting mounting plates 2, which are connected by trusses 10,11 together to form a rigid unit. Furthermore, the fitting system consists of hinged to the fitting plates 2 hinge chains 12 which hold the footrest 5. In this case, hinged to the fitting plates on lever 13, 14 support members 15,16 holding the seat part 4 and means of which the seat part 4 from a displaced to the front edge of the chair base position according to Figure 1 in a displaced to the trailing edge of the seat rest position shown in FIG 2 and Figure 3 is adjustable. The articulated scissors 12 are swung by the displacement of the seat part 4 from the basic position in the rest position and swung back by shifting back into the basic position. Each articulated scissors consists of scissor levers 17,18,19,20, which are hinged together (at 21, 22 and 23), wherein the free ends of one and two scissor levers 17,18 each on a fitting plate 2 and the free ends of a third and fourth lever 19,20 are hinged to a footrest 5 bearing coupling 24. A first lever 17 is extended over the pivot point 25 on the fitting plate 2. This extension is the lever 13. At the extension (13) in each case the first front support member 15 of the seat part 4 is articulated. At the rear end of each fitting plate 2 each have a lever 14 is hinged, on which the second and rear support member 16 is articulated.
    The two rear support members 16 are connected to each other by a rigid cross member 26 from which a support lever 27 protrudes down to the support plane of the chair. On the support lever 27, the motor housing of an electromotive linear actuator 9 is hinged, from which a spindle-like part 28 protrudes, in the direction approximately parallel to the seat surface of the seat part 4 to the front edge of the chair. On this spindle-like part 28, a driver 29 in the manner of a spindle nut, arranged and adjustable. The spindle-like part 28 is rotated by the actuator 9 and thereby the driver 29 along the spindle-like part 28 moves. At the driver 29 a connected to a pedestal of the chair lever 30 is hinged.
    The fitting plate 2 is equipped in the front area with a downwardly projecting extension 3. As can be seen from Figure 1, in the basic position of the seat of the driver 29 is arranged at a distance from the ends of the spindle-like part 28 approximately in its central region. By means of the actuator 9 Drehxing the spindle-like part 28, the entire seat part 4 is moved from the basic position to the rest position shown in FIG 2 and thereby swung out the footrest 5. The driver 29 retains its position relative to the body of the chair, while the actuator 9 along with spindle-like part and thus coupled seat part 4 and the coupled thereto backrest 6 to the rear edge of the body adjusted to a first position.
    As can be seen from Figure 2, a Reststellweg 31 is present between the free end of the spindle-like part 28 and the driver 29. The meaning will be explained later.
    The extension 13 of the first lever 17 of the articulated shears 12 is arranged with the articulation point 32 of the first front support member 15 in the basic position of Figure 1 between the front edge of the seat and the articulation point 33 of the second articulated lever 18, while in the rest position according to Figure 2 between the articulation point 33 of the second lever 18 and the trailing edge of the chair is arranged. The first lever 17 is in the rest position according to Figure 2, ie with pivoted footrest 5, at a Wegbegrenzungsanschlag 34. On the second rear support member 16, a pivot lever 35 is articulated, on which the back part 6 is fixed. Further, a toggle lever 36 is articulated between the support member 16 and the pivot lever 35, which serves to pivot the backrest 6. The toggle lever is preferably actuated against the force of a tension spring 37, between the pivot lever 35 and a
    Lever 38 of the toggle lever is clamped. By means of the actuator 9, the back part 6 is moved from a steeper basic position into a flat inclined rest position upon rotation of the spindle-like part 28 from the position according to FIG. 2 into the position according to FIG. Here, the driver 29 retains its position relative to the body of the chair, while the actuator 9 together with spindle-like part 28 is further adjusted to the rear edge of the body in a second position, which is shown in Figure 3. The travel is limited by the remaining distance 31.
    In order to be able to move the seating to a standing-up auxiliary position, as illustrated in FIG. 5, the following is provided.
    The pedestal of the chair consists of a Standfußteil 39 as coupling, are hinged to the pair of four-bar linkages 40, on the other hand hinged to the fitting plates 2 and 3 as coupling, so that the seating furniture in total from the normal position of Figure 1 in a raised, slightly after sloping downwards
    Stand-up auxiliary position according to Figure 5 is adjustable.
    The articulation points of a pair of articulated levers 41 on the fitting plates 2, 3 are formed by a rotary crosshead 42, to which the ends of the articulated levers 41 of the articulated lever pair are fixed. Of the rotary crosshead 42 of the lever 30 protrudes, which is hinged to the driver 29 of the actuator 9. The pivoting of the lever 30 is limited in the downward movement, so that it is from the stand-up auxiliary position according to Figure 5 in the normal position shown in Figure 1 is pivotally, but not beyond.
    The driver 29 is adjustable by means of the actuator 8 from the basic position of Figure 1 in the stand-up auxiliary position according to Figure 5 along the spindle-like member 28 towards the actuator 9, where appropriate, to the stop on the housing. As a result of the adjusting movement and the resulting rotation of the rotary cross-member 42, the levers of the four-bar chain 40 are raised or swiveled so that the two positions according to FIG. 1 and FIG. 5 can be adjusted.
    The limitation of the sliding movement of the seat part 4 forward takes place by a stop of the cross member 11 on parts of the rear stop 16, so that the seat part 4 from the rest position shown in Figure 2 in the basic position shown in Figure 1 is displaced, but not beyond.
    The invention is not limited to the embodiment, but in the context of Offenbarlang often variable.
    All new, disclosed in the description and / or drawing single and combination features are considered essential to the invention.
