- a seat depth adjustment has preferably been telescopic Excerpts on, by pushing in or pulling out these extracts the contact surface for the thighs individually can be adjusted. Full support of the pad and thus the thigh is with this Type of construction only possible with a great deal of effort.
- the invention has for its object a chair of the type mentioned kind of improving that he's one with one simple structural design provided seat depth adjustment which is easy to use.
- the invention solves this problem by means of a chair of the type mentioned, in which the front edge of the Upholstery on one with one arranged below the seat Shaft-connected control element is attached and attached to the Shaft is arranged at least one toothed washer over which a Endless toothed belt or an endless chain is guided, the Belt or chain firmly connected to the seat shell and a second tooth lock washer that is common with the first tooth lock washer is adjustable parallel to the seat shell, is guided, so by pulling up or pushing down the control element the front edge of the pad is adjustable forwards or backwards is.
- This makes it easy to constructively realize a seat depth adjustment that also at the same time is easy to use for the user.
- the shaft can expediently be connected to the at least one first toothed washer and the at least one second toothed washer be arranged on a common component that is relative adjustable to the seat shell.
- the component can advantageously be a web, on the front end the shaft with the first pulley and on the rear end of which is supported by the second toothed washer.
- the Web on a rod connected to the seat shell guided socket be attached.
- the rod and bushing can be connected to each other be lockable.
- two first toothed disks can be arranged on the shaft, via the each run an endless toothed belt or an endless chain are.
- the shaft can be a hexagon shaft and the ones mounted on it Toothed lock washers can each have a hexagon hole.
- the power transmission from the control element to the toothed lock washer reliably thanks to a positive connection ensured.
- Fig. 1 shows a control element 10 in the form of a rib, the a manner not shown here with a shaft 11 connected is.
- the endless timing belts 13 are by means of a fastening element 15 with the in Fig. 2nd seat plate 21 firmly connected.
- the second tooth lock washers 14 and the shaft 11 with the first toothed disks 12 are each supported on a web 16.
- the webs 16 point for this purpose, an opening 32 to receive the shaft 11.
- the Crosspieces 16 are connected to a socket 19 by means of screws 17 and 18 screwed tight.
- the bushings 19 are in turn on rods 20 slidably guided.
- Fig. 2a shows the seat plate 21 of a work chair, the a cushion 22 is covered.
- the a cushion 22 is covered.
- At the bottom of the seat shell 21 one of the webs 16 can be seen on which one of the second toothed disks 14 and the shaft 11 are mounted.
- Pulleys 24 lock the endless toothed belt 13, which over the Toothed washers 12 and 14 is guided. So one on the A person sitting in a chair does not have the front edge with their thighs 23 of the cushion 22 accidentally adjusted backwards.
- On the shaft 11 is the rod-shaped control element 10 mounted, also with the front edge 23 of the cushion 22 is connected.
- Fig. 2b shows how the front edge 23 of the cushion 22 through Swiveling the control element 10 backwards and downwards is rolled up, which results in a lower seat depth than that shown in Fig. 2a.
- Fig. 3 shows a detailed view of the seat plate 21, by means of Screws 30 and 31 the rod 20 is arranged.
- the Web 16 is in the manner shown in Fig. 1 with the socket 19 connected, the socket 19 on the rod 20 in Longitudinal direction of the rod 20 is displaceable. So can also the web 16, which has an opening 32 in its front region for receiving the shaft 11, in the longitudinal direction of the rod 20 are moved.
