Definitions
- the invention relates to a chair, in particular an office chair, with a tiltable by means of weight shift a frame-mounted seat plate.
- the seat plate of such chairs is used by the chair user Lean against the backrest against his body weight a spring force in the rear area inclined downwards.
- This Spring force can be adjusted individually according to the body weight of the Chair user can be adjusted so that a lighter chair user just like a heavy chair user the seat lean down solely by his body weight can without, for example, an additional To push away the edge of the table or the like.
- a chair user can feel the restoring force adjust the spring so that the seat is first by leaning down against the backrest inclines. So far, the restoring force has been set by means of a rotary knob attached below the seat.
- the invention has for its object a chair of the type mentioned Kind of going to improve that attitude the restoring force of the spring becomes more comfortable.
- the invention solves the task with a chair type mentioned, in which the seat plate in its front Half is pivotally connected to the frame and on a position further back over the seat plate at least one lever is articulated to the frame, at least one below the seat plate on the frame mounted leg spring a restoring force on the seat plate exercises and an abutment of the at least one leg spring on the seat plate depending on the body weight of the chair user is adjustable.
- the adjustment of the abutment of the leg spring is possible quickly and with almost no effort.
- the adjustable abutment as a parallel to the seat plate sliding, between the seat plate and the front Leg of the leg spring attached rod is formed so the chair user can easily and comfortably by moving the restoring force of the rod along the chair Adjust the leg spring according to your wishes.
- the adjustment of the return spring is particularly convenient make when the sliding rod at least one Side protrudes from the side of the seat plate.
- the inclination of the backrest can increase the seating comfort in a manner known per se at the same time as the inclination of the Seat plate to be adjustable, with the backrest becoming stronger tilts than the seat plate, which is ergonomically cheaper.
- the to an undesirable pressure on the legs of the chair user could lead to the inclination mechanism of the seat plate be designed so that the seat plate in its front half via at least one pivotally arranged on the seat plate Tab is connected to the frame. Then the whole Move the seat plate slightly backwards when tilting. alternative this can also be done in the front of the seat plate Area pivotable about a pivot axis fixed to the frame and the connection between the seat plate and the frame in the longitudinal direction of the chair be movable.
- Fig. 1 shows a seat plate 10, which is mounted on a frame 11 is.
- the seat plate 10 is in the rear area tiltable below (Fig. 2).
- In the front half is the seat plate 10 via a pivotally arranged on the seat plate 10 Tab 12 connected to the frame 11.
- Another one the rear position is the seat plate 10 via a lever 13 articulated to the frame 11.
- Below the seat plate 10, a leg spring 14 is mounted on the frame 11.
- the leg spring 14 exercises one with its legs 19 and 20 Restoring force on the seat plate 10 thus pushes us seat plate 10 inclined downward in the rear area Discharge back up to the original position.
- the Leg spring 10 receives its pretension by adding to the seat plate arranged abutments 15 and 16 on their legs 19th and press 20.
- the abutment 16 can be along an elongated hole 17 are moved. By moving the abutment 16 in the slot 17 can bias the leg spring 14 can be set individually, which means the restoring force the spring 10 depending on the body weight of the chair user can be varied.
- the abutment 16 has in the starting position of the seat plate 10 shown in FIG. 1 no contact to the leg 19 of the spring 14, which is on Support frame 11. Only when the seat plate 10 is inclined (Fig. 2), the abutment 16 comes into contact with the leg 19. The leg 20, however, is in all positions of the Seat plate 10 on this.
- the abutment 16 is in the example shown as a rod formed, which protrudes laterally on the seat plate 1.
- the backrest of the Chair not shown here are attached.
- At Inclination of the seat plate 10 does not incline here the backrest or the extension 18 shown in more detail simultaneously with the seat plate 10, but the Backrest or the extension 18 tends more than that Seat plate 10. This is ergonomic for the chair user cheaper.
