6 4 2 7 6 Adjustable office chair Regleröar arbetssto1

The invention relates to an adjustable chair, in particular an office chair, in which the seat frame fits on rollers or recesses which can move on the chair frame so that when the seat moves forward its rear part lowers and the front part 5 rises or remains substantially level. , and the backrest frame of which is articulated from the bottom to the frame of the seat: a lm tatty is centered on the chair frame! enr that when the Kali of the adventurer sits backwards, the seat part moves forwards, the backrest and the seat part can be locked in place by fixing the frame of the seat part with respect to the frame of the chair 10 ..

In particular, the invention is directed to · ..

The invention will now be described, by way of example, with reference to an embodiment of the invention shown in the figures of the accompanying drawing, to which the invention is not limited.

Figure 1 shows a cross-section from the side of a product structure according to the invention.

Fig. 2 shows a diagram illustrating the operation of the chair adjustment mechanism when adjusting the position of the chair.

The frame of the chair is formed by a tubular frame in which the handle supports 1 and 2, the tubular guides 3 under the seat connected to them, a pair of guides fit at an angle of about 20-30 ° at the rear and at an angle of 5-10 ° at the front inclined t upwards, and the guidewires interconnect the intermediate tubes 4 and 5, to which the height adjustment of the chair inert leg 6 oi: is attached.

20 The seat part 8 of the chair consists of a tubular mngost j 7, a cushion jr attached to it, a curtain il uv. ta. The body 7 has InakrruiU: roller pairs 9 and LO, on top of which it is possible to enter it along the nhdepa ^ 3. In connection with the rollers 9,10, the stops 11 pivoting under the guides 3, which prevent the Seat Lrtonmi, are from the frame.

The tubular frame 12 of the backrest 15 is connected to the seat part 7 via the joint 13 and to the frame of the armrest 1 by means of the articulated arm 14 and the joint by means of pins 3 3 and 19. corresponding. The frame i 2 is provided with suitable padding and upholstery, which are of a type known per se and have a more detailed condition. there is no reason to comment in this context.

The position of the seat and at the same time the backrest is determined by the throttle 16 mounted between the seat frame 7 and the chair frame 3, which can be locked to a certain length by means of a lever 17 35.

When the backrest is rear A relaxed 15 ", the lever arm 1 '·" is preferably substantially horizontal.

Thus, by choosing the length of the lever arm 14 and the size and position of its pivot sector, as well as the slope of the front and rear guides, the correct trajectories of the chair back 15 and seat 8 can be realized while providing a simple and durable chair.
