Definitions
- the invention relates to a swiveling seat arrangement with a backrest, which by simple body pressure changes the Angle of the backrest.
- Such seating arrangements are particularly suitable as office chairs, but can also as system seating, for example as equipment for waiting rooms and other public spaces, in different modes of transportation, like buses, trains or planes, or as leisure furniture, like TV armchairs or garden chairs.
- the complicated structure of a conventional synchronous mechanism often prevents the simple exchange of individual components the seating arrangement, e.g. B. the exchange of seat or back.
- the difficult to solve connection with a any existing base is often seen as a nuisance.
- From DE 38 00 754 C2 is a seat for an office chair with a adjustable seat and backrest by shifting body weight known.
- the seat and back part can be relative to one Frame pivoted like a swing around a fixed swivel axis become.
- the conventional seat arrangement according to DE 38 00 754 C2 with the has fixed swivel axis in terms of stability and the seating comfort the following disadvantages.
- the movement sequence corresponds to a children's swing (swing principle).
- the seat part moves to the rear, so that the person is, for example, one To reach the desk, must tilt further forward. This shifts the focus away from the front Pivot axis. In this situation, the seated person must support with your legs to avoid tipping forward.
- An additional disadvantage is that the person for the opposite movement in the non-pivoted state Get momentum or give yourself a "jerk". For pivoting a strong body shift is necessary.
- Pins or gears that run in slots have an undesirable high mechanical resistance. In the course of use, for example, it occurs due to material deformation or contaminants to an undesirable Jamming or squeaking.
- the object of the invention is to provide an improved seating arrangement specify the disadvantages of conventional swivel Seating arrangements can be overcome and in particular a stable Sit with and regardless of the body weight of the person sitting synchronized movement of seat and backrest with little effort allows.
- the seating arrangement is also intended to be one Reliable and maintenance-free construction even with prolonged use have.
- the object of the invention is also with such improved seating arrangements and equipped seating Specify applications of the seating arrangement.
- a pivotable seat arrangement at least one mechanical component contains a rolling motion on a supporting frame element can execute.
- an adjustment can be made the rolling characteristics to different requirements realize in swiveling seat arrangements.
- This rolling characteristic largely determines the adjustment behavior of the seating arrangement.
- the supporting frame element is designed so that it the adjustment possibilities of the seat arrangement are not limited and does not affect seating comfort.
- a generic seating arrangement in this regard continue to develop that at least one rolling component are rigidly connected to a carrier, on the turn the seat is attached, whereby when pivoting the seat the carrier relative to the at least one rolling surface is pivoted.
- a backrest is connected to the rolling component, which is pivoted by the roll angle in the event of roll.
- a rigidly connected to the rolling component Carrier to which a seat is attached.
- the carrier between the rolling component and the seat surface ensures that depending on its length during the rolling motion in addition to the change in angle the carrier position a horizontal shift the position of the seat. This horizontal shift The greater the distance, the greater the seating position between the seat and the rolling surface.
- the rolling The component forms a seesaw, the movement of which swivels the backrest and a horizontal shift the seat, combined with a slight increase or Lowering the seat, is connected.
- the term “rolling component” refers expressly also on each in the movable part of a pivotable Seat arrangement integrated surface, the rolling movement according to the invention allows.
- the term carrier includes each stable connection between the seat and the rolling Component sufficient to support the weight of a seated person to be transferred to the rolling surface.
- the seating arrangement according to the invention denotes the ability that the position and orientation especially of the backrest and the seat of the user, especially a seated Person by shifting weight or by pushing off with the legs or arms are changed. It’s both a pretense, d. H. a move to a changed position and fixation in this, as well as panning, d. H. a dynamic Behavior includes.
- the seating arrangement under load can already be sufficient Stability of the seating arrangement is ensured in every position become.
- the rolling surface i.e. the load-bearing frame element, well below or at the same height relative to the center of gravity of the movable part of the seat assembly, for example a straight rolling surface
- the center of curvature of the rolling Adjust the surface of the rollable component so that he clearly above the center of gravity of the movable part of the seat assembly lies, which leads to self-stabilization similar to that Principle of a "standing man" leads.
- the supporting frame element has a flat rolling surface, while the rolling component has a curved surface, the Shape depending on the practical requirements for the seat and Swivel behavior and the stability of the seat equipment selected is.
- for additional stabilization be provided to make the rolling surface itself concave and through a possibly variable radius of curvature the rolling Guide component like in a bowl.
- the radius of curvature of the rolling component or the rolling surface can to be changed to the edges of each area to realize certain pivoting behavior. For example, it can be provided that the force required to the movable part of the seat assembly from a central position swing out, increases with increasing swivel angle.
- a particularly advantageous embodiment is that load-bearing frame element or the rolling surface located thereon to be installed in a position that is above the center of gravity of the movable part of the seat assembly.
- the connected to the rolling component Carrier of this can lead down to whatever is hanging position of the seat connected to this support provides.
- the seat thus forms together with the carrier and the rolling component a pendulum assembly, which without Presence of resetting mechanical components a stable Starting position.
- the one connected to the swivel assembly via the rolling component Backrest leads to an additional influence the mechanical equilibrium. Because the influence of weight the backrest with an average load Seat arrangement is small, this remains on the situation the mechanical balance when used as intended the seating arrangement low. With a suitable choice of the curvature of the surfaces touching when rolling, the length of the carrier, on which the seat hangs, and positioning of the rolling surface in relation to the center of gravity, the size of the restoring torque can be if the pendulum assembly is deflected, that it’s about the same size as the reverse one Tilting moment caused by the leaning of the seated on the Backrest is created. Because both moments are linear from body weight of the seated, no weight-dependent restoring forces are required generated by additional mechanical components.
- the dimensioning of the moving parts and / or the shape and location of the rolling surface can be such that a possible accurate cancellation of the mutual torques takes place, too a pivoting of the seat arrangement due to very low pressure forces leads. This is indicated by a mere swiveling Body pressure is often perceived as very pleasant.
- parts of the seating arrangement can also be dimensioned in such a way that the opposing moments are not complete pick up, which causes the backrest to pivot a - albeit minor - but clearly noticeable Force must be applied.
- a particularly advantageous embodiment with a high rolling surface is ideal for seating furniture that has armrests.
- the size of such Seating is hardly different from one without the pivotability shown.
- Further advantageous configurations include a lockability the swiveling seat arrangement in every adjustment position. This can be done by positioning mechanical locking Components between the rolling surface and the rolling surface happen. These components have a high coefficient of friction on, even low pressure forces are sufficient to achieve an effective To achieve a wedge effect and an effective stop of the rolling motion to effect and thus a further pivoting prevent.
- the surfaces that come into contact when rolling off can also be designed or positioned so that a small Restoring force generated in the area of maximum pivoting will be in positions near the starting position, however for instability of the system, for example due to a convex elevation of the rolling surface, is taken care of. That requires constant active maintenance of the standard seating position, however, allows pivoting at the same time in a clearly backward and stable sitting position when leaning, which are taken for occasional relaxation can. In this embodiment, too, the required Actuating forces are kept low.
- the pivoting characteristic of the invention Seat arrangement by the design of the rolling Areas on the one hand and the rolling surfaces on the other hand become.
- the rolling component can be particularly advantageous and / or the supporting frame element with an interchangeable Roll surface to be provided.
- This can be done, for example, by a Exchange insert can be realized, which can be done in a few simple steps, z. B. with a bayonet or a Velcro can connect the respective part and which contains a surface, the respective requirements for the desired rolling characteristics is adjusted. So an application with a circular rolling surface quickly thanks to an insert with convex parabolic or hyperbolic rolling surface or through an insert that contains a rolling surface in which different troughs for fixing different swivel positions be replaced.
- end stops be equipped with detachable locks to the To temporarily fix the seat in the swiveled state.
- Another advantageous embodiment includes a geometric Optimizing the rolling surfaces also an additional Influencing the rolling characteristics through elastic or damping components. For example, by occupancy the rolling surface with a permanent plastic material Damping the pivoting movement can be realized. Thereby there is constant resistance even with optimized geometry against a swiveling of the sitting position, which leads to that on the one hand the sitting position is not too easy due to low Movements are blocked, but on the other hand not for everyone deliberate pivoting any existing lock released must become. At the same time, this embodiment has the advantage that almost the same positioning force for each swivel angle is required. With adequate design of the damping effect are already mentioned friction-increasing wedge elements unnecessary to fix the seating position.
- Another advantage of storage on rollers is the low Shift of the center of gravity in the horizontal direction, what a high level of stability even with free-standing seating provides.
- Independent of the principle of the rolling movement according to the invention and the associated synchronization of a pivoting the backrest with a forward displacement of the seat it is appropriate to use either the supporting frame element and / or to design the rolling component so that during the rolling movement a lateral guidance of the rolling component given is.
- This can be done, for example, by one another coordinated running profiles of rolling surface and / or rolling surface will be realized. Due to the size and at the same time small It also stresses the contacting surfaces frequent pivoting in seat arrangements according to the invention very little wear. At the same time it is like that realized pivoting almost silently.
- appropriate materials or corresponding coating of Moving parts with noise-reducing materials can Noise development can be reduced even further. Come for this especially felt or rubber coverings.
- a rigid connection can be provided be so that the seating arrangement when swiveled like a Rocking chair behaves.
- a modified configuration exists in movably connecting the seat to the carrier. at a pivoting becomes the horizontal and vertical position, but not predetermined the orientation of the seat. The alignment the seat is rather actively carried out by the person sitting, what to avoid incorrect strain in the lumbar region leads and an additional active-dynamic component forms.
- the flexible connection between the seat and the beam can advantageously be done by elastic connecting elements.
- the seating arrangement is also suitable for an installation without contact with the ground.
- Appropriate carriers on which the rolling surfaces are located or attached by changing systems can be, for example, directly on walls or other Support structures can be mounted, so no restriction there is ground clearance and still full Functionality can be used. The same applies to use in transportation.
- the provision of the rolling surfaces can also be done quickly to be assembled frame element, for example, by Clamping devices or simply attaching them to a table top can be.
- the rolling surfaces are approximately in the Level of the table top, a seat shell as a movable assembly be put on with the corresponding rolling Components is equipped and forms a child seat that in the pivoting options according to the invention with the Table is connected.
- the same principle can be used with the corresponding Design of the assembly means and the frame element realize any place that is short term with a comfortable Seat equipment is to be provided.
- the construction principle according to the invention advantageously enables easy adjustment of the seating arrangements various requirements resulting from the respective use result.
- the rigid components through their connection to the load-bearing frame element are marked and the movement of all moving Components determined by the movement of the rolling component a particularly simple expandability can be added to other Realize constructive details, which makes them particularly versatile the seating arrangement leads.
- other accessories that change with the seating position to be moved with, through more or less direct Connection with the rolling component, for example by mounting on the seat or the carrier already mentioned attach, which automatically results in a synchronized movement of these accessories.
- the seat arrangement according to the invention is particularly suitable for one Use with changing loads, d. H. a change between typical working postures, for example in the office, and typical sitting postures that are mainly used for relaxation (so-called power napping). Especially with relaxed postures one comes due to a lack of active maintenance of muscle tension physiological and as complete as possible support of the body, especially the spine, too. It is therefore particularly advantageous for the seat arrangement according to the invention to be equipped with backrests that optimally perform this function guarantee. Two parts have proven to be particularly advantageous Proved backrests with headrests that are divided that the headrest is firmly connected to an upper backrest area is that acts as a shoulder and neck support. Another lower backrest area is for supporting the lower back area, especially the lumbar area.
- the relative movement of the two backrest parts advantageously takes place synchronized with the change of seating position, i.e. during the movement from an upright to a backward sitting position and vice versa.
- Wise connecting means used between moving and rigid parts of the seat assembly.
- the seat arrangement according to the invention stands for an attachment of a Synchronization mechanics on rigid parts practically the whole load-bearing frame element available.
- the invention is illustrated below with reference to a Embodiment with certain mechanical parts for implementation the rolling motion when pivoting the seat assembly explained without referring to the specifically described form of each Parts to be restricted. Rather, the invention can also realized with other forms of the supporting and / or moving parts be a rolling motion when pivoting the Allow seating arrangement. Details of seating arrangements that whose upholstery and covering are known per se not described below. Also known per se Parts especially of office chairs, such as. B. a synchronous mechanism, not described below.
- Fig. 1 shows an office chair without covering and cladding.
- a mobile foot 1 known per se is via a gas pressure spring 2 attached a supporting frame member 3, the fork-shaped to the level of the armrests (not shown here) and there is completed by two horizontal beams 4, the point essentially in the direction of the armrests.
- the tops this carrier is flat and forms the rolling surfaces 5 for the sequence of movements according to the invention.
- a rolling component 6 On each of these rolling surfaces is a rolling component 6, which on his Underside is limited by a convex surface 7, which on the rolling surface 5 of the supporting frame element 3 can roll.
- Attached to this rolling component 6 is a downward one leading carrier 8, on which a seat surface via connecting elements 9 10 is attached.
- the connecting elements 9 are rigid, depending on the embodiment or formed elastic. Swiveled with rigid connecting elements 9 the seat 10 with the carrier 8.
- elastic Connecting elements 9 is a pivoting of the seat surface 10 possible about a horizontal axis transverse to the seat direction.
- a simple one Backrest 11 the angle of which with respect to the rolling Component 6 can be preset with a clamping device 12 can.
- the carrier 8 is pivoted through the same angle which the seat 10 hangs. This leads to a horizontal shift the seat 10 with only a slight change in height the seat surface 10.
- the elastic connecting elements 9 it is possible to seat 10 regardless of the pivoting always keep in a horizontal position.
- the rolling motion can be done by positioning appropriate hard rubber rollers 13, 13 'between rolling surface 5 and rolling component 6 are inhibited, thereby fixing the respective Sitting position occurs.
- the underside of the rolling component 6 has a curved one Surface that in cooperation with the preferred flat rolling surface 5 determines the pivoting behavior of the seat arrangement.
- the geometry of the component 6 is different Swivel features adjustable. For example, an asymmetrical Curvature can be provided, which is relative to the seat direction flatter at the front (with a larger radius of curvature) and towards the rear is steeper (with a narrower radius of curvature), where the radius of curvature from the center to the edge of the bottom can be changeable. Influencing the swivel movement by varying the shape of the rolling surface important advantage of the seating arrangement according to the invention
- the structure of the swivel mechanism is also considerably simpler than, for example, a chair with synchronous mechanism.
- the seat assembly of the present invention has the following in use special advantage. Because the weight of a seated Person over the rigidly attached to the rolling components Lever-type carrier on the rolling components attacks, they perform a real rolling movement, whereby the point of contact between the rolling components and the rolling surface depending on the swivel direction on the rolling surface emotional. The current center of curvature moves accordingly of the rolling components through which the current Swivel axis runs. The pivot axis thus moving stays close to the center of gravity, making a more stable Sitting behavior and even a growing with increasing external steering Braking effect is achieved. The swivel movement is now automatically damped, there is no need for limiters. The sedentary people can with a self-stabilizing training the rolling components by simply picking up the feet automatically swing back from the floor to the horizontal position.
- Fig. 2 In the front view shown in Fig. 2 is particularly the Design of the supporting frame element 3 and the rolling surfaces 5 recognizable. Due to the fork shape of the frame element 3 comes 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). To ensure lateral guidance, the rolling components are designed so that they have a smooth surface 7 that roll on the rolling surface 5 can and on the outside next to the load-bearing Frame element 3 have an edge bead 14, which is a guide guaranteed along the rolling surface 5.
- the seating arrangement according to the invention has the following others Benefits.
- the seating comfort is due to the increased stability significantly improved.
- the seat arrangement has one simple mechanical construction with symmetrical components, that can be produced with just one tool.
