Definitions

  • the invention relates to a piece of work seating, with a backrest hinged to a seat and with a base frame on which the seat is supported in its front region via a joint and the backrest is supported by a support lever articulated at lumbar height, the support lever being approximately below the center of the seat on Underframe is articulated.
  • the seating furniture in which the seat inclination and the back inclination can be changed in a certain ratio to one another are known in various embodiments.
  • the seating furniture In the unloaded state, the seating furniture, when the seat is generally horizontal, has an angle of 90 ° between the seat and the backrest, which angle is maintained as long as the user is in a working position only loaded the seat. If the user wants to lean back into a rest position, the known seat furniture tilts - generally only after releasing a lock - the seat surface slightly downwards by a small angle at the rear end and swivels the backrest by a two to three times larger Angle backwards, with angles of up to 130 ° between the seat and back surface for the rest position.
  • the invention has for its object to provide a work seating with synchronous seat and backrest adjustment that - while avoiding complex mechanics - an effective support also in the area of the lumbar vertebrae and in the rest position approximately from the hollow of the knee to the shoulder blades Ensuring the support surfaces fit against the user's body.
  • the solution to this problem is achieved in that the seat and the backrest merge into one another via an arcuate, bendable intermediate part and that the connecting line of the two articulation points of the support lever in the basic position at an angle between 0 to 25 °, preferably between 15 to 25 ° , is inclined to the vertical.
  • the steep position of the support lever in the basic position ensures that when changing from an upright working posture to a reclined posture, the backrest is first moved considerably more horizontally backwards than downwards. In conjunction with the widening and quasi-rolling intermediate part between the seat and backrest, this provides a uniform and extensive support of the entire body at the transition to the rest position.
  • the anatomy of the human body is taken into account in such a way that when changing to a rest position, the upper body not only swings backwards like a lever around a joint, but also that the body also over the pelvis of the pelvis rolls a little to the rear and the upper body also collapses somewhat while moving the at least lower lumbar vertebrae back.
  • the seating furniture according to the invention is adapted to these body movements and proves to be a very tight, comfortable support.
  • the backrest is convexly curved in the vertical longitudinal section towards the seat and that the lower half of the backrest is inclined forward in the basic position. This enables a very good support of the lower lumbar vertebrae and the cross area when sitting upright, in which the lower part of the spine is also slightly inclined forward.
  • the seat leads according to the invention a clear one Evasive movement backwards so that the user's pelvis can roll and the spine can move into a more extended and backward inclined position.
  • the distance between the two articulation points of the support lever is approximately twice as large as the distance between the lower articulation point of the support lever and the front seat articulation point and that these articulation points define an acute-angled triangle in the basic position.
  • the constellation of these articulation points results in a coordinated behavior of the seat and backrest inclinations in the different seating positions of the human body.
  • the flexible intermediate part proves to be of great advantage in the invention since it makes mechanical sliding joints, toggle levers or similar complex mechanics superfluous.
  • the seat pivot is about a quarter of the seat depth behind the front seat edge and that the front third of the seat is bent downward to a greater extent than the front seat edge is pivoted up when the furniture is pivoted back.
  • the lower articulation point of the support lever can be offset from the center of the seat by about 10% of the seat depth, which among other things results in a great stability of the seating furniture against tipping.
  • the backrest can be concavely curved in cross section to the seat and can be provided with a strongly drawn lumbar bulge, on which the upper articulation point of the support lever is arranged.
  • these measures improve the support and, on the other hand, enable the support levers to be set very steeply without impairing the appearance of the seating furniture.
  • the seat and the backrest consist of a one-piece plastic shell.
  • the shell can have semi-cylindrical bearings with a snap edge at the front seat pivot point for receiving a horizontal bearing axis attached to the base frame.
  • the seating furniture can be manufactured as a chair or as an armchair with armrests. In the latter case, elastic armrests are provided, which are attached to the articulation points of the seat and backrest on the seating furniture. These armrests can already be dimensioned accordingly deliver the entire return spring force for the seating furniture alone. Instead of or in addition to the springback via the armrests, it can also be provided that the support lever is loaded directly or indirectly at its lower end by a return spring.
  • the seating furniture can be equipped with a device for adjusting the bias of the return spring in order to be able to adapt to the weight and size of the user.
  • the chair can be equipped with a device for locking the support lever at least in the basic sitting position.
  • either a torsion axis as the lower linkage of the support lever or coil or leaf spring or a gas spring can be provided as the return spring, which act on a cam projecting radially from a lower bearing shaft.
  • a column-shaped base frame 1 and 2 has a column-shaped base frame 1, from which at the upper end, approximately below the middle of the seat, a flat, broad support arm 2 protrudes obliquely upwards, which carries a horizontal axis 3 'at its front end, on which the seat 4 is articulated in its front area.
  • a horizontal shaft 5 ' is mounted, at the two ends of which a support lever 6 is rigidly attached, the other end of which is approximately at lumbar height on a backrest 7 of the seating at position 8 at approximately lumbar height are articulated.
  • the articulation points 3, 5 and 8 form an acute-angled triangle, the connecting line V between the articulation points 5 and 8 being approximately twice as long as the distance between the articulation points 3 and 5 on the base frame.
  • the connecting line V between the articulation points 5 and 8 of the support lever 6 is inclined at an angle ⁇ of approximately 20 ° with respect to the vertical. 1 is determined by a stop (not shown) to the front.
  • the seat 4 and the backrest 7 consist of a one-piece plastic shell and are connected to one another in a virtually articulated manner by a middle or intermediate part 9 which is almost flat in cross section.
  • the radius of curvature of this flexible intermediate part 9 is approximately 10 cm in the basic position.
  • the backrest 7 is convex towards the seat - seen in the vertical longitudinal section - and the lower half 10 of the backrest 7 is inclined forward in the basic position.
  • the backrest 7 is also curved in a horizontal cross-section concave to the seat and with a strongly drawn loin Bulb 11 provided, at which the upper articulation points of the two support levers 6 are designed in the form of bearing eyes 12 (FIG. 5).
  • the front seat pivot point 3 lies about a quarter of the seat depth T behind the front edge 13 of the seat, and the front third of the seat is bent downward.
  • the seat 4 is substantially horizontal and the backrest 7 in the middle e-oriented vertically out of g, as shown by the dash-dot lines S and R in Fig. 1 indicated.
  • the entire seat pivots on the one hand about its front articulation point 3 downwards by a small angle ⁇ , but the relatively steep support lever 6 of the backrest 7 additionally forces a pivoting movement backwards by an angle ⁇ .
  • a considered point P lying at the lumbar level thus executes a movement component X in the horizontal direction, which is considerably larger than its movement component Y in the vertical direction, when moving into the position P 'of the rest position. This corresponds to the natural movement of the body (see FIGS.
  • FIGS. 1 and 2 shows the chair according to FIGS. 1 and 2 in a further development - as an armchair with elastically resilient armrests 19 which are fastened to the seat or to the backrest in the region of the articulation points 3 and 8.
  • the seat and backrest each comprise an approximately U-shaped support tube frame 21, 22, in the open ends of which bent spring steel pieces 23 are inserted with their ends.
  • the bent spring steel pieces 23 in turn form the flexurally elastic zone analogous to the intermediate part 9 of the embodiment according to FIG. 1, and they are also strongly curved in accordance with the seat shell representations according to FIGS. 5 and 13.
  • the two support levers 6 and G ' are each mounted in the base frame via a torsion axis 24, 24', which deliver the resilience.
  • the torsion axes are received by a cross member 25 to which they are rigidly attached in the center, see also FIG. 6.
  • FIG. 6 illustrates a device with which the clamped middle ends of the torsion axes 24/24 'can be preloaded.
  • return springs are preferably provided in the form of cylindrical coil springs or a leaf spring assembly, which are arranged within the support arm 2.
  • the leaf spring assembly 2S lies on one End between an L-shaped receptacle 29 arranged on the support arm 2 and an abutment 30 screwed onto the support arm 2. Its free end lies on the foot end of a cap screw 31 which passes through a cam 32 which is rotatably connected to the horizontal shaft 5 by a clamping ring 33 ' connected is.
  • the leaf spring assembly 28 is bent around its abutment 30 and is thus preloaded.
  • the restoring force is exerted on the backrest 7 by two helical springs 34 arranged parallel next to one another.
  • the coil springs 34 enclose bolts 35, which at one end penetrate a movable abutment plate 36, which forms a support surface for the coil springs 34.
  • the second support surface of the coil springs 34 forms a pressure plate 3S, which is firmly connected to the bolts 35.
  • the bolts are each rotatably connected to a cam 39 of the horizontal shaft 5 ′ via a fork head 37.
  • the bolts 35 are mounted in corresponding bores in the rigid support plate 40 and also protrude beyond the support plate 40 in the rest position.
  • the support plate 40 carries an L-shaped bend 41 with an inclined plane 42
  • Bearing piece 43 on the inclined plane 42 of which a slide 44 is seated, which is provided with a threaded bore directed onto the inclined plane.
  • a knurled head screw 45 which the bend 41 and the bearing piece 43 with a large. If clearance is penetrated and screwed into the slider 44, the abutment plate 36 can be moved together with the slider and the spring preload can thus be set.
