Definitions

  • the invention relates to a pivotable seat assembly with backrest that allows a change in the angle of attack of the backrest by simple body pressure.
  • Such seating arrangements are particularly suitable as office chairs, but can also be used as system seating, for example as equipment of waiting halls and other public spaces, in various means of transport, such as buses, trains or aircraft, or as leisure furniture, such as TV chairs or garden chairs.
  • the complicated structure of a conventional synchronous mechanism often prevents easy replacement of individual components of the seat assembly, eg. B. the replacement of seat or backrest.
  • the difficult to be solved connection with a possibly existing base frame is often perceived as disturbing.
  • adjustable seat assemblies pivoting the seat back to a rearward position typically increases the distance between the upper body and a reference point, such as a computer keyboard. For larger pivoting angles, it can come to that convenient until then handling objects at a workplace suddenly out of reach, but at least outside of an area in which a comfortable handling is possible lie. As a result, a change in the position of the entire seat assembly is required by dislocation, which is a considerable inconvenience especially in heavy office chairs or seating without mobile undercarriage.
  • a seat for an office chair with an adjustable by body weight shift seat and back is known.
  • the seat and back can be pivoted about a fixed pivot axis relative to a frame like a swing.
  • the conventional seat assembly according to DE 38 00 754 C2 with the fixed pivot axis has the following disadvantages in terms of stability and seating comfort.
  • pivoting is realized, which corresponds to the movement of a children's swing (swing principle).
  • the seat portion moves backwards so that the person, for example, to reach a desk, must continue to tilt forward.
  • the center of gravity shifts forwards away from the Pivot axis.
  • the seated person needs to rest his legs to avoid tipping forward.
  • An additional disadvantage is that the person has to get in the opposite movement to the opposite movement in the swing or give a "jerk". For pivoting a strong body displacement is necessary.
  • JP 51-141074 discloses a chair in which the seat and back is suspended on both sides in the armrests, each with two rollers in curved scenes.
  • a chair which has a curved sitting or lying surface, which is supported by rollers movably mounted in a frame, so that the chair can be transferred from a sitting position to a lying position.
  • US Pat. No. 2,217,756 discloses a chair that can be tilted backwards on a ball rail mounted on an upwardly curved guide rail.
  • US 6 056 363 discloses an armchair which is mounted rolling on a curved rail, so that it is pivotable between sitting positions and lying positions.
  • the object of the invention is to provide an improved seating arrangement, with which the disadvantages of conventional pivotable seat assemblies are overcome and in particular allows a stable sitting and independent of the body weight of the seated with little effort a synchronous movement of the seat and backrest.
  • the seat assembly should also have a reliable and maintenance-free construction even with prolonged use.
  • the object of the invention is also to specify equipped with such improved seating arrangements seating and applications of the seat assembly.
  • a pivotable seat assembly includes at least one mechanical component that can perform a rolling movement on a supporting frame member. Due to the design of the area on the supporting frame element, on which the rolling movement takes place, and / or the surface of the rolling element, which comes into contact with the supporting frame element, an adaptation of the rolling characteristic to different requirements in pivotable seating arrangements can be realized. This rolling characteristic significantly determines the adjustment behavior of the seat assembly.
  • the supporting frame member is designed so that it does not limit the adjustment of the seat assembly and does not affect the comfort.
  • the invention proposes in particular further to develop a generic seat assembly to the effect that at least one rolling element are rigidly connected to a carrier to which in turn the seat is fixed, wherein when pivoting the seat surface of the carrier relative to the at least one Rolling surface is pivoted.
  • a fundamentally changed pivot principle is realized according to the invention, which in contrast to the conventional swing principle (fixed pivot axis) has a movement sequence such as a cradle, in which the current pivot axis during the pivoting movement in the same direction as the center of gravity of the seated person shifts (weighing principle).
  • a movement sequence such as a cradle, in which the current pivot axis during the pivoting movement in the same direction as the center of gravity of the seated person shifts (weighing principle).
  • a backrest is connected, which is pivoted in the case of rolling around the rolling angle.
  • rigidly connected to the rolling component is a support to which a seat is attached.
  • the carrier between the rolling element and the seat ensures that that, depending on its length in the rolling movement in addition to the angular change of the carrier position, a horizontal displacement of the position of the seat takes place. This horizontal displacement of the seating position is greater, the greater the distance between the seat and the rolling surface.
  • the rolling element forms a rocker whose movement is associated with a pivoting of the backrest and a horizontal displacement of the seat, associated with a slight increase or decrease of the seat.
  • rolling element expressly refers to any integrated in the moving part of a pivotable seat assembly surface that allows a rolling movement according to the invention.
  • carrier encompasses any stable connection between the seat surface and the rolling element that is sufficient to transmit the weight of a seated person to the rolling surface.
  • "Pivotability" of the seat assembly according to the invention refers to the ability to change the position and orientation, in particular of the backrest and the seat, by the user, in particular by a seated person by shifting his weight or by repelling his legs or arms. There is both an adjustment, d. H. a movement in a changed position and fixation in this, as well as a pivoting, d. H. includes a dynamic behavior.
  • the supporting frame element has a flat rolling surface, while the rolling element has a curved surface, the shape of which is selected depending on the practical requirements for the seating and pivoting behavior and the stability of the seat device.
  • the radius of curvature of the rolling member or the rolling surface can be changed to the edges of the respective surface in order to realize a specific pivoting behavior. It can be provided, for example, that the force required to swing out the movable part of the seat assembly from a central position increases with increasing pivoting angle.
  • an active-dynamic sitting is provided near the middle position, which should correspond to an upright posture.
  • a sufficient pressure force on the backrest can be compensated, allowing a relaxed leaning.
  • a particularly advantageous embodiment is to attach the supporting frame element or the rolling surface located thereon at a position which lies above the center of gravity of the movable part of the seat assembly.
  • the carrier connected to the rolling element can lead from this downward, which always ensures a suspended position of the seat connected to this carrier.
  • the seat thus forms together with the carrier and the rolling component a pendulum assembly that assumes a stable starting position even without the presence of restoring mechanical components.
  • the backrest connected to the pivoting assembly via the rolling element leads to an additional influence on the mechanical equilibrium position. Since the influence of the weight of the backrest is low in an average loaded seat assembly, this influence on the position of the mechanical balance during normal use of the seat assembly remains low.
  • the magnitude of the return torque can be adjusted to about the same with a deflection of the shuttle assembly is great, as the acting in the reverse direction tipping moment, which arises by the leaning of the seated person to the backrest. Since both moments depend linearly on the body weight of the seated, no weight-dependent restoring forces must be generated by additional mechanical components.
  • the dimensioning of the moving parts and / or the shape and position of the rolling surface can be such that the most accurate possible cancellation of mutual torques takes place, which leads to a pivoting of the seat assembly by very low pressure forces. This is often perceived as very pleasant when pivoting by mere body pressure.
  • parts of the seat assembly can also be dimensioned so that the oppositely acting moments do not cancel completely, which means that for pivoting the backrest - albeit small - but clearly noticeable force must be applied.
  • a particularly advantageous embodiment with high-lying rolling surface offers seating furniture that have armrests. It is possible to accommodate inside these armrests both rolling surfaces on supporting frame elements and on this in the form of rockers rolling off mechanical components to which the seat hangs. This automatically provides the advantage of a relatively high position of the rolling surface, which is limited only by possibly relevant standard specifications (DIN, etc.), associated with high stability by the pendulum action and at the same time effective use of anyway for the armrests to be provided space , The size of such a chair thus hardly differs from one without the pivoting shown.
  • DI possibly relevant standard specifications
  • the surfaces coming into contact during rolling can also be designed or positioned in such a way that a small restoring force is generated in the area of maximum pivoting, but in positions near the starting position for instability of the system, for example by a convex elevation of the rolling surface, is provided.
  • This requires a constant active maintenance of the standard seating position, but at the same time allows pivoting in a clearly rearward and leaning against leaning seating position, which can be taken for occasional relaxation.
  • the required actuating forces can be kept low.
  • the pivotal characteristic of the seat arrangement according to the invention can be predetermined by the design of the rolling surfaces on the one hand and the rolling surfaces on the other hand.
  • one or both of said surfaces may be convex or concave depending on the desired pivotal characteristic.
  • one of the surfaces mentioned can be flat and the other surface convex.
  • the rolling component and / or the supporting frame element can be particularly advantageous to provide the rolling component and / or the supporting frame element with an exchangeable rolling surface.
  • This can be achieved for example by a change of use, which can be done with a few simple steps, eg. B. can connect via a bayonet or a hook and loop fastener with the respective part, and containing a surface that is adapted to the particular requirements of the desired rolling characteristic.
  • an insert with a circular rolling surface can be rapidly replaced by an insert having a convex parabolic or hyperbolic rolling surface, or by an insert containing a rolling surface in which various troughs for fixing various pivoting positions are located.
  • end stops can be equipped with releasable detents in order to temporarily fix the seat in the pivoted state.
  • the pivoting characteristic is already given by placing the movable part of the seat assembly on the supporting frame member with the corresponding rolling surface. Connecting or movement influencing elements may therefore be superfluous, allowing a quick replacement of the moving parts of the seat assembly. This may be particularly important if such seating arrangements are used as system seating, and a rapid change of a large number of seats is required, for example, in a change in the color design of the furniture in public spaces.
  • a further advantageous embodiment includes a geometric optimization of the rolling surfaces beyond an additional influence of the rolling characteristic by elastic or damping components. For example, by occupying the rolling surface with a plastic material, a permanent damping of the pivoting movement can be realized. This creates a constant resistance to a pivoting of the seating position even with optimized geometry, which leads to on the one hand, the seat position is not adjusted too easily by slight movements, but on the other hand not for any desired pivoting a possibly existing lock must be solved. At the same time, this embodiment has the advantage that almost the same actuating force is required for each pivoting angle. With sufficient design of the damping effect already mentioned friction-enhancing wedge elements for fixing the seating position superfluous.
  • Another advantage of storage on wheels is the small shift of the center of gravity in the horizontal direction, which ensures a high level of stability even with free-standing seating.
  • This can be achieved for example by coordinated running profiles of rolling surface and / or rolling surface. Due to the size and at the same time low stress on the contacting surfaces, even with frequent pivoting in seating arrangements according to the invention, very little signs of wear occur. At the same time, the pivoting realized in this way is almost silent.
  • the noise-reducing materials the noise can be reduced even further. For this purpose, in particular pads made of felt or rubber in question.
  • the seat is connected to the rolling element.
  • a rigid connection can be provided, so that the seat assembly behaves like a rocking chair during pivoting.
  • a modified embodiment is to connect the seat movable with the carrier. When pivoting, the horizontal and vertical position, but not the orientation of the seat is predetermined. The alignment of the seat is rather active by the sitter, which leads to the avoidance of incorrect loading in the lumbar region and forms an additional active-dynamic component.
  • the movable connection between the seat and the support can advantageously be effected by elastic connecting elements.
  • the seat assembly Since only the provision of one or more sufficiently solid rolling surfaces is required for the functioning of the seat assembly according to the invention, on which the movable assembly can roll, the seat assembly is also suitable for installation without contact with the ground. Corresponding support on which the rolling surfaces are located or mounted by changing systems, for example, can be mounted directly on walls or other support structures, so no limitation the ground clearance takes place and still the full functionality can be used. The same applies to a use in means of transport.
  • the provision of the rolling surfaces can also be done on a quickly mounted frame member that can be attached, for example, by clamping means or mere plugging on a table top.
  • a quickly mounted frame member that can be attached, for example, by clamping means or mere plugging on a table top.
  • Are the rolling surfaces approximately in the plane of the table top can be placed as a movable assembly a seat, which is equipped with corresponding rolling elements and forms a child seat, which is firmly connected to the table according to the invention.
  • the same principle can be realized with appropriate design of the mounting means and the frame member at each place, which is to be provided at short notice with a comfortable seating device.
  • the construction principle according to the invention advantageously allows a problem-free adaptation of the seat arrangements to a wide variety of requirements resulting from the respective use. Due to the consistent division of the assemblies used in rigid and movable components, wherein the rigid components by their connection to the supporting frame member are characterized and the movement of all movable components is determined by the movement of the rolling element, a particularly simple expandability can be realized by other structural details, which leads to the special versatility of the seat assembly.
  • the seat arrangement according to the invention is particularly suitable for use with alternating load, ie a change between typical working postures, for example in the office, and typical postures that serve predominantly relaxation (so-called power napping). Especially in relaxed postures is due to lack of active maintenance of muscle tension of a physiological and as complete as possible support of the body, especially the spine, a special significance. Therefore, it is particularly advantageous to equip the seat assembly according to the invention with backrests that optimally ensure this function.
  • Two-part backrests with headrest have proven to be particularly advantageous, which are divided so that the headrest is firmly connected to an upper backrest area, which acts as a shoulder and neck support. Another lower back area is designed to support the lower back, especially the lumbar region.
  • the relative movement of the two backrest parts is advantageously synchronized with the change of the sitting position, ie during the movement from an upright to a backward posture and vice versa.
  • synchronization connecting means are used in a known manner, which are to be mounted between movable and rigid parts of the seat assembly.
  • the entire supporting frame element is available for attachment of a synchronization mechanism to rigid parts.
  • Fig. 1 shows an office chair without covering and paneling.
  • a supporting frame member 3 is attached via a gas spring 2, the fork-shaped up to the level of the armrests (not shown here) and is completed there by two horizontal support 4, which point in the direction of the armrests substantially ,
  • the tops of these carriers are flat and forms the rolling surfaces 5 for the movement sequence according to the invention.
  • a rolling element 6 which is bounded on its underside by a convex surface 7, which can roll on the rolling surface 5 of the supporting frame member 3.
  • Fixed to this rolling element 6 is a downwardly leading support 8 to which a seat 10 is fastened via connecting elements 9.
  • the connecting elements 9 are formed depending on the embodiment rigid or elastic. With rigid connecting elements 9 pivots the seat 10 with the carrier 8. By elastic Connecting elements 9 is a pivoting of the seat 10 about a horizontal axis transverse to the seat direction possible. Also connected to the rolling element 6 is a simple backrest 11 whose angle with respect to the rolling element 6 can be preset with a clamping device 12. During a rolling movement of the rolling element 6, the backrest 11 is pivoted about exactly the rolling angle. At the same angle pivots the carrier 8, on which the seat 10 depends. This leads to a horizontal displacement of the seat 10 with only a small change in the height of the seat 10. The elastic connecting elements 9, it is possible to keep the seat 10 regardless of the pivoting always in a horizontal position. The rolling movement can be inhibited by the positioning of corresponding hard rubber rollers 13, 13 'between rolling surface 5 and rolling component 6, whereby a fixation of the respective sitting position occurs.
  • the underside of the rolling element 6 has a curved surface which, in cooperation with the preferably flat rolling surface 5, determines the pivoting behavior of the seat arrangement.
  • different pivot characteristics are adjustable. For example, an asymmetric curvature may be provided which is flatter forward (with a larger radius of curvature) forward and rearward (with a narrower radius of curvature) relative to the seating direction, the radius of curvature being variable from the center to the edge of the bottom.
  • the influence of the pivoting movement by varying the shape of the rolling surface is an important advantage of the seat assembly according to the invention.
  • the structure of the pivoting mechanism is also considerably simpler than, for example, in a chair with synchronous mechanism.
  • the seat assembly according to the invention has the following particular advantage in use. Because the weight of a sedentary Person attacks on the rigidly attached to the rolling elements support in the manner of a lever on the rolling elements, they perform a real rolling movement, with the contact point between the rolling elements and the rolling surface moves depending on the pivoting direction on the rolling surface. Accordingly, the current center of curvature of the rolling components, through which the current pivot axis extends. The thus moving pivot axis remains in the vicinity of the center of gravity, so that a more stable seating behavior and even a growing with increasing external steering braking effect is achieved. The pivoting movement is thus automatically damped, limiter can be omitted. The seated person can automatically swing back to the horizontal position by simply picking up the feet from the floor in a self-stabilizing configuration of the rolling elements.
  • Fig. 2 In the front view shown in Fig. 2 is particularly the embodiment of the supporting frame member 3 and the rolling surfaces 5 can be seen. Due to the fork shape of the frame member 3, there is no reduction in the space available on the chair.
  • the flat rolling surfaces 5 are located approximately at the level of the armrests (not shown here).
  • the rolling elements are designed so that they have a smooth surface 7, which can roll on the rolling surface 5 and each have on the outside next to the supporting frame element 3 a bead 14 having a guide along the rolling surface 5 guaranteed.
