Seat for public transport

Te üie innovation concerns a seat for public persons- ';! traffic, consisting of a profile frame with a cushioned seat cushion covered by a seat cover made of a heavy flammable and low-smoke material.

H There are essentially two types of public seats

f * Means of transport, especially trams, underground trains and S-Bahn

_V: NEN. In the first type, a profile frame is provided which

;! - has a solid plate that serves axs abutment for seat springs. at

the second type has the suspension via the seat material.

Both types have the disadvantage that they are relatively high

'' have to be built and also for upholstery materials made of heavy

ί flammable material that is only in a relatively low level

(; Strength can be produced, are not suitable.

The innovation is directed to a seat of the first-mentioned type, by means of which the aforementioned disadvantages are avoided , and the particular for the use of flame retardant and low-smoke cushioning materials is suitable. Seats according to the innovation can have an opposite State of the art considerable weight savings and can be produced with a considerable reduction in production costs.

This object is achieved according to the invention by a seat with the features mentioned at the outset, which continues to do so ι is characterized in that at least two opposing profile strips of the seat one facing the center of the frame,

overhead groove, the web of which has recesses that are open at the top, and all profile strips have one open to the center of the frame, horizontally running groove for receiving a fire-retardant plate and one on the outside of the frame, downwards Have an open groove for receiving the ends of the seat cover.

A preferred embodiment of the seat according to the innovation results from the characterization of claim 2.

Further advantageous embodiments of the innovation emerge from the following description, with reference to the drawings Is referred to. Show it:

Fig. 1 in a perspective view, partially cut away, an overall view of the seat according to the invention, and

FIG. 2 shows a section along line I-I of FIG. 1 FIG. 3 shows a section along the line H-II in FIG. 1.

The frame consists of the profile strips 1,2 with at least the opposing profile strips formed identically are. The connection of the profile strips 1,2 with each other is done using screws through holes 3 at the corners out vmd can be held in a screw channel.

There are zigzag springs between the profile strips (for example 1) 4 used, which support a seat cushion 5 made of flame-retardant and low-smoke material.

If profile strips 2 are used with different heights, for example to compensate for the inclination of the

(I lit

Glawe, DeIfs, Moll & Partner - ρ 11457/85 - page 4

Seat frame can be possible, this compensation is done by additional support materials 6.

The seat cushion 5 is covered in a known manner by a seat cover 7.

As shown in Fig. 2, the profile strip 1 is a hollow profile made of light metal with a substantially rectangular cross-section.

As shown in FIG. 2, the profile strip 1 has an upwardly open groove on the side facing the center of the frame whose web 9 has an inwardly facing bead 10 and recesses 11 that are open at the top.

The profile strips 1 and 2, the profile strip 2 also being a hollow profile made of light metal with a rectangular cross-section is, have to the frame center, at the same distance from the lower edge of the profile, a horizontally running groove 12 into which a fire-retardant plate can be used. A downwardly open groove 14 is arranged on the outside of the frame, into which the seat cover 7 ends and can be fastened.

Inside the profile strips 1 and 2 is a screw channel provided, the distance of which from the walls of the profile strips is fixed by a web 16.

To build a seat, the four profile strips 1, 2 are detachable connected to one another via the screw channel 15. Before the fourth profile strip is attached, the groove 12 the plate 13 in the already connected profile strips 1,2 inserted. The zigzag springs 4 are inserted into the groove 8 via the recesses 11 under tensile stress and secured by the bead 10 against slipping out.

The seat cover 7 is tensioned via C.as seat cushion 5 placed on the springs, and it is fastened in the groove 14. This can be done by a clamping device or by nailing to a wooden wedge (not shown)
