lichen a bowl-shaped shape with a bottom part 5 and an upright lip 6 running around the circumference of the shell. The bottom part of the shell is with it provided below facing grooves 7, which are formed during the casting or injection molding process in this and for receiving serve to hold the seat serving portions 8 of the chair frame.

Furthermore, an inner or upper shell 9 is provided, which is also made of a suitable synthetic plastic and is essentially the shape of an inverted bowl with a circumferential, having upwardly facing lip 10. On the top On the surface of the inner shell there is a padding 11, for example made of foam plastic, rubber or some other Upholstery material and at least partially in di <& circumferential groove 12 formed between the upwardly facing lip and the sides of the bowl-shaped shell extends into it. An upholstery cover fabric 13 is stretched over the upholstery and over the upwardly facing lip into the interior of the shell, for example up to the point indicated by the reference numeral 14, at which the cover material by means of brackets or otherwise attached to the inside of the shell.

The shape of the upper part of the lip 6 on the lower shell can best be seen in FIG. 5 · Kin essentially vertical wall section 15 of the lip terminates in an inwardly rounded section 16 on the inside of the lip forms a shallow groove 17 around its entire circumference near the top of the lip.

The upwardly facing lip 10 is thinner than the remainder of the upper shell and has such a thickness that gives the lip a sufficiently high elasticity. In addition, the size of the inner shell is such that it can be pressed into the outer shell when it is covered with the upholstery material, whereby the elastic The lip of the inner shell is initially deformed inwards and over the rounded portion 16 of the lip located on the lower shell slides away and then in turn deformed outside so that the peripheral edge of the elastic lip 10 engages in the peripheral groove 17 on the outer shell and holds the upholstery fabric in place. The underside of the inner shell can be secured with downward facing posts 18 (Fig. 4) be provided, which rest with their lower ends on the inside of the outer shell. Screws 19 ', through which the chair frame is connected to the seat surface can be screwed into these posts 18.

With such a structure, no part of the inner shell 9 is visible in the assembled state of the seat, at the same time the fastening of the cover material is covered. The outer shell 4 and not the padding takes up most of the stress, especially when it comes to a chair that is shared with others Chairs stacked together »can be grounded by nesting the chairs. While the inner shell is anatomical Shaped canoe and should be adapted to the body shape, the shape of the outer shell is not subject to any requirements this kind.

The same structure is used for the backrest 3 of the chair, the shape being designed differently in accordance with the different intended use. So can the outer shell, for example, be provided on both sides with a projection 19 in which there is a cylindrical Recess for receiving the ends of the backrest forming pipe sections 20 are located, as well as with a Ashtrays 21 provide his penau as with the seat the backrest also consists of an inner and an outer molded piece, and the upholstery cover is over a led away upward or outward-facing lip, which is elastic below the edge of the outer shell
