Definitions

  • the invention relates to a chair with a support frame, a seat plate and a backrest, which is provided with an arm extending below the seat plate, which is pivotally articulated on the support frame, the arm connecting the rear part of the seat plate via a pivotable connection with the latter carries and the front part of the seat plate is connected to the support frame via a bearing device and the bearing device has at least one spiral spring member which is held on one side on the support frame and on the top of which rests a bearing part attached to the seat plate in the region of its spring-deflectable free end.
  • a chair of this type is known for example from DE 196 07 136 A1.
  • the chair described therein has one.
  • Seat plate and a backrest connected to it for common adjustment, an upright section and a lower arm projecting laterally therefrom.
  • the seat plate is pivotally connected to a support frame fixed to a base near its front edge via a pivot bearing.
  • the lower arm of the backrest protruding under the seat plate is pivoted to the support frame and supports the rear part of the seat plate.
  • the swivel bearing consists of the swivel shaft and an elongated slot link, which is designed to rise towards the backrest.
  • the swivel shaft is fixed on the underside of the seat, while the slotted slot is fixed on the support frame.
  • the rear part of the seat plate is articulated between the articulation point of the arm on the support frame and the upright section of the backrest on the arm.
  • a chair of the type mentioned is known from DE 12 97 306 B.
  • the rear part of the seat plate is carried by the bending spring member which is connected to the support frame in the region of its end facing the front of the chair. In the central area of its longitudinal extent, it is supported on a support element of the support frame.
  • the pretensioning of the spiral spring element must be changed greatly depending on the weight of the user. If a chair is intended for use by several different, heavy people, significant changes in the setting must be made to enable ergonomic sitting. There is also a risk of incorrect settings. Furthermore, the range within which the setting of the pretension of the spiral spring element can be changed is limited.
  • a relatively expensive gas pressure spring is provided in a conventional manner between the swivel frame for the backrest and the support frame of the chair.
  • the front part of the seat plate is carried by a carrier connected to the support frame and the rear part of the seat plate is articulated to the swivel frame.
  • Bending spring members are provided between the support bearing the front part of the seat plate and the swivel frame to support the gas pressure spring.
  • the object of the invention is to provide an ergonomically advantageous, but simply constructed and very inexpensive to manufacture synchronous mechanism, in which weight compensation is also achieved for users of different weights.
  • the spiral spring member When the backrest is pivoted backwards, the spiral spring member is deflected against the spring force, the guide surface forming a counter bearing.
  • the bearing on the top of the spiral spring member or another bearing part attached to the seat plate can rest against this guide surface. Since in the undeflected state the flexible spring element is prestressed against the bearing part resting on its upper side, this bearing part or can be used when the seat plate is loaded by a user - except during peak loads when lowering down or when the user sits completely in the area of the front edge on the seat plate the further bearing part attached to the seat plate is held against the guide surface, as a result of which a controlled synchronous sequence is achieved when the backrest is pivoted backwards.
  • a leaf spring assembly which has advantageous resilient properties and is very inexpensive can advantageously be used as the bending spring member.
  • the chair according to the invention shown in FIGS. 1 and 2 has a support frame 1. This can be mounted in a conventional manner pivotable about a vertical axis 2 at the upper end of a central vertical column 3, which is supported by a cross 4.
  • a backrest 5 of the chair is connected to an arm 7 which extends below a seat plate 6 and which is articulated on the support frame 1 so as to be pivotable about an axis 8.
  • the arm 7 carries the rear part of the seat plate 6 (including upholstery) via a connection which can be pivoted about the axis 9, a tab 10 projecting downwards being provided for the pivotable connection of the seat plate 6 to the arm 7.
  • the front part of the seat plate 6 is connected to the support frame 1 via a bearing device 11.
  • the bearing device 11 has a spiral spring member 12 in the form of a leaf spring assembly, which is held on one side on the support frame 1 on the side of its end facing the backrest 5.
  • the other end 13 of the spiral spring member 12, which is free in this exemplary embodiment, can be deflected in a spring-elastic manner and lies in the area adjoining this end 13 the to the front of the chair falling down 14 of the flexible spring member on the seat plate 6, namely on a protruding from this down tab 15 attached bearing part 16, so that the front part of the seat plate 6 is supported by the flexible spring member 12.
  • the bearing part 16 also bears against a guide surface 17 which is arranged above the bearing part 16 and forms a counter bearing upwards.
  • the top 14 of the spiral spring member 12 and the guide surface 17 are here - seen in side view - at an angle to each other and run towards each other in the direction of the back of the chair.
  • the bearing part 16 is pulled backwards by the connection of the seat plate 6 with the arm 7 along the guide surface 17, the spiral spring member 12 being deflected downward.
  • the angle between the guide surface 17 and the upper side 14 of the spiral spring member 12 influences the strength of the deflection of the spiral spring member 12 and thus the strength of the spring force opposing the deflection.
  • the spring force opposing the deflection also increases as a function of the deflection angle of the backrest 5.
  • a stop is provided, which is not shown in the drawing for the sake of clarity.
  • this stop could be formed by a leg which limits the movement of the bearing part 16 along the guide surface 17 to the rear and projects downward from the guide surface 17.
  • a clamping bolt 18 is provided which passes through the spiral spring member 12 through a through hole 19.
  • the clamping bolt 18 has an external thread and is screwed into an internal thread of a part 20 rigidly connected to the supporting frame 1.
  • the clamping bolt 18 has a radially projecting collar 21, which rests on the spiral spring member 12 in the area around the through opening 19.
  • the spiral spring member 12 is in the area of the through hole 19 of the support frame 1 or of the internal thread provided part 20 of the support frame 1 and is biased by the collar 21 against the bearing part 16.
  • this pretension can be adjusted by screwing in the clamping bolt 18 to a greater or lesser extent.
  • the pretensioning means that the bearing part 16 does not lift off the guide surface 17 even when the seat plate 6 is loaded by a user. By adjusting the preload, the spring force opposing a pivoting back of the backrest 5 can be changed.
  • two separate bearing parts 16 can also be provided for this purpose, which can be arranged one behind the other, for example in the image plane of FIGS. 1 and 2.
  • the bearing part bearing against the guide surface 17 and also attached to the seat plate could be attached rigidly or displaceably against the force of a spring to the seat plate or to a part connected to it.
  • this can be designed as a roller, in particular if rotatable on the seat plate 6 for contact with the upper side 14 of the spiral spring member 12 and for contact with the guide surface 17 or an associated part arranged rollers are provided, a slight wear of these surfaces 14 and 17 and the bearing parts is achieved.
  • spiral spring members 12 arranged one behind the other, for example perpendicular to the plane of the drawing in FIG.
  • two spiral spring elements 12 arranged in the form of leaf spring assemblies which are arranged on both sides of the section 23 of the support frame 1 and extend under the front area of the seat plate 6, on the upper sides 14 of which a bearing part 16 designed as a rotatable roller rests and between which the section 23 with the the guide surface 17 provided thereon, on which a roller also lies.
  • These rollers can all be rotatably mounted about the same axis, which is held on both sides by tabs 15.
  • part of the leaf springs of the leaf spring package lying below the top leaf spring are shorter than the top leaf spring and end before the free end of the leaf spring top leaf spring.
  • the bearing part 16 rests on a weakened region of the spiral spring member 12, as a result of which better suspension of the seat surface is achieved in the non-pivoted state of the backrest.
  • the guide surface 17 is approximately horizontal in the exemplary embodiment shown, an inclination of the guide surface with respect to the horizontal is also possible, which is preferably less than 45 °. An inclination of less than 30 ° is particularly preferred.
  • the angle between the top 14 of the spiral spring member 12 and the guide surface 17 is preferably in the range between 15 ° and 50 °.
  • clamping bolt 18 having an external thread
  • another clamping device could also be provided to achieve a pretensioning of the spiral spring member 12.
  • other flexible spring members than a leaf spring assembly would also be conceivable, for example rod-shaped flexible spring members.
  • a leaf spring package however, has a particularly good spring characteristic, at an affordable price.
  • the backrest In the position of the backrest which is pivoted backwards, it could have been pivoted, for example, by an angle of 24 °, while the seat has been pivoted by an angle of 8 °.
  • the front edge of the seat surface preferably remains at the same height or lifts slightly when the backrest is pivoted back.
