Definitions
- the invention relates to a chair, in particular office chair, with an over a backrest carrier articulated on a backrest and with one synchronously movable seat, the front area via a sliding guide and the rear area via a seat link with the seat support connected is.
- the synchronous mechanism serves to adjust the backrest change the position of the seat at the same time.
- the invention is therefore based on the object of a chair, in particular a chair Office chair, with a particularly suitable and easy-to-implement synchronizing mechanism specify.
- the invention is based on the consideration that with a chair or Seating with adjustable seat and adjustable backrest the adjustment options from the seat on the one hand and the backrest on the other can be viewed independently.
- the construction thus points initially two degrees of freedom.
- the backrest can be adjusted only a single degree of freedom when the articulation of the backrest on the seat support in a simple manner via the rigid with the backrest connected backrest support is realized on the seat support via a single Rotational axis is rotatably attached.
- the seat can be more complex Have adjustment options, being analogous to the adjustability of the backrest nevertheless it can be assumed that the setting options the seat can be written with a single degree of freedom.
- the movement can do both a translation and a tilting movement or a combination of different forms of movement.
- a coupling of the movements of the seat on the one hand and the backrest on the other hand it should first ensure that every possible position a position of the seat is assigned to the backrest, as a result of which the entire Construction is limited to one degree of freedom.
- These requirements as well as a coupling mechanism that is both permanently stable and structurally simple are rotated by a sliding guide with the seat connected seat handlebars met the backrest support. This is given a particularly simple synchronous mechanism.
- the driver pin on the backrest support and the elongated hole guide can be provided in the seat link.
- the sliding guide provided in the front seating area can be adjusted in the seat support provided slot and one guided therein, rigid with the seat connected axis or be realized by a cylinder. Regardless of that advantageously an obliquely downward in the direction of the seat support front sliding guide provided. Due to the inclined arrangement of the as Length compensation element effective front sliding guide of the seat will not only an undesirable lifting of the front edge of the seat when Avoid tilting the backrest, but rather lowering it The front edge of the seat is reached when the backrest is tilted back. This Lowering is more pronounced, the more the inclination of the sliding guide deviates from the horizontal and runs towards the vertical.
- the seat link connected to the seat outward inclination of the seat handlebars forward and down becomes more ergonomic
- the seat increases when you lean back the backrest mainly lowers in its rear area, while at the same time the front edge of the seat back and forth moved down. This gives the seat in the desired manner in its rear area a greater range of motion than in the front Area.
- the chair 1 designed as an office chair according to FIG. 1 comprises a fixed one only partially shown stand 2 connected seat support 3. With the seat support 3, a backrest 5 is rotatably connected via a backrest link 4. The The backrest 5 is from the rest position shown in FIGS. 1 and 3 out into the reclined position shown in FIGS. 2 and 4 or Tilt position backwards. The backrest 5 is inclined by a rotation about a pivot point D1. For this, the one with the backrest 5 is fixed connected backrest link 4 connected to the seat support 3 via an axis of rotation A, wherein the pivot point D1 essentially through the central axis of this axis of rotation A is given.
- the seat link 7 is with the seat support 3 via a swivel D2 and with the seat 6 in the rear Area, i.e. in the rear seat 6 facing the backrest 5 connected rotatably via a swivel joint D3.
- the pivots D2 and D3 are again realized by corresponding axes of rotation A, via which the seat link 7 with the seat support 3 on the one hand and with the seat 6 on the other hand rotatably connected is.
- the seat 6 is connected to the seat support 3 via a sliding guide 8.
- the sliding guide 8 can in a manner not shown as an elongated hole in the seat support 3 and guided rigid therein connected to the seat 6 Axis 9 or - as shown - designed as a cylinder guided in the seat support 3 his. This is then rotatably connected to the seat 6 via the axis 9.
- the sliding guide 8 is inclined in the direction of the base 2.
- the seat link 7 lies with the seat surface 6 connecting upper pivot D3 based on the seat 6 lower than that the back link 4 with the seat support 3 connecting pivot D1, while this is in the rest position below the pivot point D3.
