Definitions

  • the invention relates to a chair, in particular a chair, with a chair mechanism, which allows a change in the angle between the seat and back and thereby generates an angle of change counteracting restoring force at least in one direction of movement.
  • Seating furniture are often adjustable to allow the user to change his sitting position.
  • the adjustability includes a change in the angle between the seat surface and the backrest, the angle change being caused by pivoting back, i. a backward pivoting, the backrest is accomplished.
  • pivoting back can be conveniently achieved by the user leaning back against the backrest, a mechanism is conveniently used to return the backrest to push the backrest toward its home position (before pivoting back).
  • the necessary force (restoring force) can be made available, for example, by pistons, coil springs or torsion springs.
  • a chair of this kind is for example from the EP 1989 963 B1 known.
  • the office chair described therein has a seat plate and a backrest.
  • the Backrest is attached to an approximately L-shaped support arm, which extends to below the seat plate and there runs out into a spiral spring, wherein it is rotatably connected to the chair base at the transition to the bending spring.
  • the free end of the spiral spring is supported on the underside of the seat plate.
  • the spiral spring is not formed there as part of the support arm, but held between three support elements. Two of the support members are disposed on one side of the bending spring respectively at the ends thereof, while the third is positioned on the opposite side of the spiral spring and between the other two support members.
  • the approximately L-shaped support arm has an extension which forms one of the terminal support elements, which presses on pivoting back of the backrest from above on the bending spring.
  • the spring stiffness can be adjusted via the central support element, which is connected to the chair base via a clamping bolt.
  • From the WO2008 / 000295A1 is a chair with a curved spring element known, one end of which is fixedly connected to the base of the chair and the other end fixed to a relatively movable seat support. Upon enlargement of the angle between a likewise existing backrest support and the seat carrier latter is pulled backwards from the backrest support and pulls the associated with the seat support end of the spring element, which increases its curvature and a restoring force is generated.
  • the EP2050360A1 teaches a chair with a complicated shaped spring element, which has a plurality of spring arms, wherein the spring element is connected at several points fixed to the chair mechanism. A bending load applied to the free ends of the spring element or to protuberances thereof when the machine leans back on the mechanism produces a return action on the backrest.
  • the present invention provides an alternative chair mechanism and a chair with such a mechanism.
  • the mechanics should be simple and thus inexpensive to manufacture. Further advantages and objects of the present invention will become apparent from the following description.
  • a seating furniture is disclosed
  • the seat of the chair serves a person to sit on it.
  • the term "seat” is here to be understood in general as a part of the chair, which is designed to serve the purpose mentioned. It can further be provided that the seat surface or the thighs of a person sitting on it are aligned substantially horizontally. Depending on the application, a deviation from the horizontal of up to 30, 20 or 10 degrees is conceivable.
  • the seat is connected via a seat support to a base, wherein the seat surface and / or the seat support are formed either immovable or movable relative to the base.
  • the seat surface and / or the seat carrier may be designed to be displaceable and / or rotatable relative to the base. In this case, a displacement from the front to the rear and vice versa is preferred, or a rotation about a rotation axis running from left to right, in particular substantially horizontal.
  • the backrest of the chair is used for leaning against a person sitting on the seat.
  • the term "backrest” is generally to be understood as a part of the seat which is designed to serve the stated purpose. It can further be provided that, in the upright position of the backrest, the backrest is oriented essentially upright or vertically and / or the back of a leaning person is oriented substantially vertically or upright. Depending on the application, a deviation from the vertical of up to 40, 30 or 20 degrees is conceivable.
  • the backrest is connected to the base via a backrest support.
  • the backrest and / or the backrest support are preferably movable relative to the base and / or the seat surface and / or the seat support, in particular rotatable or pivotable in order to achieve the change in the angle between the backrest and the seat surface.
  • they are formed by the seat and / or seat support and / or from the base rotatable (or pivotable). It is advantageous if the backrest is movable together with the backrest support.
  • the backrest support is substantially L-shaped and / or has a leg extending essentially along the backrest and transversely to a leg connected to the base, which advantageously extends to below the seat surface and / or the seat support .
  • the backrest support can be connected on a left and a right side with the seat support and the bending spring can then extend to between these connection points.
  • the seat and / or backrest may be pliable or soft (e.g., padded or resilient) for comfort, in particular, more pliable or softer than the user's body surface so as to conform to the shape of the body when sitting.
  • the backrest is arranged at an angle to the seat surface.

  • the seating furniture has a mechanism for changing the said angle between the seat surface and the backrest, which is designed to generate an enlargement opposite and / or counteracting restoring force when the angle is increased.
  • the restoring force preferably acts on the backrest support. It leads to a movement of the same in the direction back to its starting position.
  • the restoring force is generated by means of a bending spring, which is advantageously a leaf spring. It may be designed for this purpose to learn a change in shape, in particular a change in their bending, when changing the angle between the seat and backrest.
  • the bending spring could be substantially straight before the shape change, ie in its initial shape, and have a curvature or a greater curvature (as before the shape change) after the change in shape.
  • the stored by the change in shape in the spiral spring energy can then convert them into the restoring force, the bending spring returns to its original shape.

Due to the connection between the backrest support 55 and the seat support 35, the seat support 35 is pulled backwards and, depending on the embodiment of the connection, when the backrest support 55 is pivoted backwards. This prevents withdrawal of the shirt from the pants when leaning back. However, the seat support 35 could also be immobile relative to the base 13 and / or be firmly connected thereto.

Since the support member 85 is spaced from the axis of rotation 95, rotation of the back support 55 results in rotation of the support member 85 and movement (in response to movement of the seat back support 55) to and from the flexure spring 73. Regardless of the specific embodiment, it is advantageous if one of the support elements 85 is designed to be movable, with its movement being coupled to the movement of the backrest support 55 and the movement path being the location at which the bending spring 73 is in the starting position of the backrest support 55. or the space she occupies.
