Foam seating furniture.

The fire refers to seating made of foam, in particular Shell armchairs, which consist of a foam body, and which are preferably attached to a wooden or steel frame are.

It is already known to cast the body of seating furniture from foam in a mold, and this body in certain places such as covering the seat, the backrest, the top of the armrests with softer foam afterwards, the for example is glued on. This has the disadvantage that the connection between the two layers is not perfect and that it is also difficult to combine large areas at the same time to glue. When you simply hang up such

Layers, slippage of these layers cannot be ruled out, even if, for example, the edges of the layers are covered with adhesive strips or the like. Are provided.

The aim of the innovation is to create seating furniture made of foam, in which the parts made of flexible foam are applied in a particularly simple and durable manner.

According to the innovation, this is achieved in that the body of the chair consists of rigid foam and that at certain points a layer of soft foam is poured onto the body.

Rigid foam and / or flexible foam on polyurethane are preferred: base built.

The places where soft foam is poured onto the body of the chair are places of particular stress on the chair, so that it is doubly important here that it is flawless There is a connection between the support layer and the body. By pouring on the soft foam layer, it becomes flawless Connection guaranteed to the greatest possible extent, because the two parts cast with one another are evenly and permanently inseparable from one another are connected. The soft foam can, for example, be poured onto the body at certain points, but it can the entire body can also be provided with a layer of soft foam in the manner of a cover, whereof then preferably on the particularly important places the thickness of the poured-on layer is chosen to be thicker than in other places.

The process of pouring the flexible foam onto the rigid foam body goes on in a known manner the body is cast from rigid foam, that this body is then given a correspondingly modified shape and the layer there is poured from soft foam. Should the whole body have a uniform strength or a strength that can be varied in certain places having a layer of flexible foam are poured, happens

this is expediently done in two stages, with the top in the first stage
/ and in the second stage the underside of the soft foam layer is poured. Then the frame is attached to the body of the chair in the usual way.

The hiring is described below in conjunction with the drawing explained using an exemplary embodiment.

Fig. 1 shows in a side sectional view an embodiment of a chair according to the invention according to the section line H-II in Fig. 2,

FIG. 2 is a sectional front view taken along line I-I of FIG. 1 and

Fig. 3 is a section similar to the representation of FIG another embodiment of the innovation.

The body 1 of the chair is cast in a conventional manner from rigid foam. It has a foot frame 2 which is also designed in a conventional manner, but which can have any other design than that shown in the drawing. A layer 3 of soft foam is poured onto the body 1 of the chair, which in the illustrated embodiment according to FIGS. 1 and 2 represents the seat surface. Furthermore, in this embodiment of a shell chair, the armrest 4 on the body 1 is pulled up sideways and a layer 5 of soft foam is also poured onto this armrest 4, which is either continuous with the layer 3 or is omitted in the almost vertical parts of the body 1 is.

In Pig. 3, the layer 6 of soft foam completely surrounds the body 1 of the chair; however, the thickness of layer 6 needs not to be constant, but rather it can, in the particularly important ones Areas, such as the backrest, the seat and the armrests, must be made thicker than in the other areas. Such a change in the layer thickness of the layer 6 can be made in the simplest possible manner by appropriately shaping the shape of the dome Way to achieve.
