Drawings

FIG. 1 is a schematic view of the chair of the present invention;

fig. 2 is a structural sectional view of the flame retardant layer of the seat of the present invention.

As shown in fig. 1 and 2, the chair back 1, the seat cushion 2, the foaming layer 3, the carbonized core layer 4, the inorganic plate layer 5, the flame retardant paint layer 6, the upright post 7, the cross beam 8, the upright beam 9 and the mounting seat 10.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 and fig. 2, the present embodiment provides a fireproof and flame-retardant seat, which includes a seat body and a seat base, wherein the seat body is mounted on the seat base. The seat body comprises a seat back 1 and a seat cushion 2, wherein the seat back 1 and the seat cushion 2 can adopt an integrated structure as shown in figure 1 or a split structure. Of course, the seat body may be provided with only the seat cushion 2 and not the seatback 1.

In this embodiment, back of the chair 1 and cushion 2 are foaming layer 3, carbomorphism sandwich layer 4 and inorganic plate layer 5 by outer (refer to the one side towards the passenger) to interior (refer to the one side towards the seat base member) in proper order, wherein, foaming layer 3 adopts PVC wood to mould the substrate, adopt the fire-retardant resin of environment-friendly to glue to bind between each layer, this structure not only can prevent effectively that the seat body from burning because of being heated, also can not warp under high temperature environment, also can satisfy the environmental protection requirement simultaneously, effectively avoid the injury that causes the human body.

In the embodiment, the outer surfaces of the chair back 1 and the seat cushion 2 are coated with the flame-retardant paint layer 6, so that the appearance can be beautified, and the flame-retardant effect can be further realized.

In this embodiment, the seat base includes the upright post 7, the cross beam 8 and the upright beam 9, and the upright post 7, the cross beam 8 and the upright beam 9 are preferably made of stainless steel, which not only ensures the bearing capacity, but also is beneficial to weight reduction.

The bottom of the vertical beam 9 is arranged at one end of the cross beam 8 in a bolt connection mode, and the lower part of the other end of the cross beam 8 is fixed at the top of the vertical column 7 in a welding mode. The chair back 1 is arranged at one side of the vertical beam 9, and the cushion 2 is arranged above the cross beam 8.

Crossbeam 8 and cushion 2 are through first mount pad 10 fixed connection, and first mount pad 10 can adopt mouth-shaped structure, U-shaped structure, zigzag structure, L shape structure etc. has first mounting hole (not shown in the figure) on first mount pad 10, pastes together between the lower surface of first mount pad 10 and cushion 2, and first mount pad 10 and crossbeam 8 are together through bolt fixed connection.
