The innovation concerns a chair with a support frame for one Seat and a backrest.

It is known, the seat and the backrest by means of a A large number of screws through a manual operation Fasten frame. This is disadvantageous because an excessive amount of time is required in relation to the other operations in the manufacture of the chair.

The innovation is based on the task of specifying a generic chair for the purpose of more efficient production on an industrial scale, in which the assembly of the various Components is simplified, but also requires less time.

According to the innovation, this aim is achieved in that it has elastic hooking devices by means of which the seat surface and the backrest are clamped or clamped to the frame.

Preferred embodiments of the innovation are shown in the drawing and are explained in more detail below. Schematischi show it

Figure 6 is a side view of the backrest according to Figure 4 in Section along the line VI-VI.

Referring first to Figure 1, the innovation according to the invention contains Chair has a rigid load-bearing frame 7 made, for example, of a metal tube shaped essentially in a conventional manner, is and has two horizontal cross bars 8, 9 on which; a seat 10 can be attached. In addition, the Frame 7 has an approximately rectangular frame 11 which is curved in its vertical plane and to which a backrest 12 is attached can be. The seat and the backrest are preferably made of plastic. As Figures 2 and 3 show, the Seat 10 anatomically shaped and contains in its lower part a large number of longitudinal reinforcement ribs 13,

which are interconnected by a pair of transverse ribs 14, 15 located near two opposite sides of the chair. Near the transverse rib 14 shows the Seat 10 has two aligned hook elements 16, which protrude downwards and face the interior of the seat are, similarly, the seat 10 carries near de-r Cross rib 15 or the like a plurality of hooking teeth. 17 that too align with each other, protrude downwards and face the inside of the seat.

The hook elements 16 allow clamping with the transverse rung 8 of the frame 7, while the hooking teeth 17 are elastic cooperate with the front cross strut 9. Note that the cross struts 8 and 9 in Figure 2 are only partially and dashed, are shown.

The seat surface 10 can therefore easily be attached to the frame 7 in a detachable manner by a simple clamping and hooking process, for which no screws or special tools are required.

Referring to Figures 4-6, the backrest 12 of the chair includes a plastic skeleton that is generally C-shaped Has cross section and the side surface fits loosely into the interior of the frame 11. On the front, the lateral surface of the backrest 12 an extension to the outside with a peripheral edge 18. On the back sits down the side surface of the backrest 12, however, in three ways

Jumps continue, similar to the edge 18, but only on one extend certain part of the circumference} is in particular a projection 19 (Figures 5 and 6) in an upper middle arranged, while two projections 20, 21 (Figure 5) extend longitudinally the vertical sides of the backrest 12 extend "

The edge 18 and the projections 19-21 cooperate in such a way that that they ensure the clamping of the backrest 12 with the frame 11 of the frame 7} are for this reason the edge 18 towards the front of the backrest and the projections 19-21 inclined towards the rear and thus form one Reception seat for the frame 11.

The hanging of the backrest 12 (which is preferably padded and covered, so that the clamping force against the frame is increased) takes place in such a way that the upper part of the backrest is inserted obliquely into the frame 11, namely as follows, that the metal tube is located between the edge 18 and the projection 19. The backrest is then brought up to the frame 11, the lower part of the rim 18 being brought to abut against the metal pipe. Then you leave the backrest slide sideways (for example to the left), following the radius of curvature of the frame 11 until the metal tube between the rim 18 and the projection 20 snap into place, which flex resiliently and therefore a further limited lateral sliding movement the backrest 12 allow. In this way it is possible to have the backrest on the opposite side as well the frame 11 to hang, the metal tube also between

the edge 18 and the projection 21 come to rest. Also the attachment the backrest 12 is thus carried out in a safe manner by means of a quick and easy clamping, which is obviously reversible and for that no special tools or additional fastening devices required are. In addition to the advantages already mentioned, given the simplicity of the described Operations of the chair in accordance with the renewal also in disassembled Condition can be shipped from the place of manufacture and assembled at the place of destination. This allows the space required decrease of chairs during transport, which is obvious is beneficial.
