Abstract

The seat for a vehicle, in particular for an aircraft, comprises a core of plastics material (16), a covering (12) of a textile material, and a layer (14) of flame-resistant polysiloxane which is applied, by brushing or calendering, to the inside of the covering (12). The flame-resistant polysiloxane preferably comprises a diorganpolysiloxane, finely-divided silica and/or other fillers, finely-divided TiO2, platinum, a hardener and a nitrogen compound. <IMAGE>

Description

SPECIFICATION A seat for a vehicle, in particular for an aircraft The present invention relates to a seat for a vehicle, in particular for an aircraft.
Extensive efforts have been made, especially in the design of aircraft interiors, to design seats in such a way that in the event of fire the flames spread as slowly as possible and thus give the passageengers sufficient time to get out of the aircraft.
Thus it is known, for example, to surround a core of plastics material with an additional thin layer consisting of a flame-retarding foam. There are, however, practical problems in applying this additional layer to the core of plastics material; the flame-retarding effect of this additional foam is, moreover, relatively poor per unit weight and so a relatively thick additional layer of foam has to be used.
Thus the present invention aims to provide a seat for a vehicle, in particular for an aircraft, which does not suffer from the above mentioned disadvantages.
A seat is proposed, in particular, in which the additional layer consisting of the flame-retarding material may be easily applied.
According to the present invention there is provided a seat for a vehicle, in particular for an aircraft, comprising: a) a core of plastics material, b) a covering of a textile material on the core of plastics material, c) a layer of a flane-retarding material between the core of the plastics material and the covering, and d) a layer of a flame-resistant polysiloxane provided on the inside of the textile material.
The advantages of the present invention derive in particular from the fact that the covering of the textile material is provided woth a layer of a flame-resistant polysiloxane; this surface material may be easily manufactured in the desired size and/or design, the polysiloxane being brushed or calender-coated onto the covering. The machines which are required for this are available in the desired dimensions so that heavy financial investment is unnecessary.
According to a preferred embodiment, the polysiloxane is applied as thinly as possible, favourable results being achieved if the layer thickness is from 0.1 to 0.6mm thick, in particular from 0.3 to 0.4mm thick.
Tests have shown that aircraft seats made in accordance with the invention can meet all the relevant requirements and can easily allow the evacuation time of 90 seconds which is laid down by American regulations.
According to one preferred embodiment a polysiloxane is used, as is described in European Patent Application No.0051212. Apolysiloxaneofthistype comprises a diorganopolysiloxane, finely-divided silica and/or other fillers, finely-divided Tio2, platinum, a hardener and a nitrogen compound.
This polysiloxane has to be hardened at a temperature above 60"C under ambient pressure or excess pressure over a pre-determined period of time, thus producing the so-called A-stage of vulcanisation.
Subsequent vulcanisation for from 1 to 24 hours may be carried out, which leads to the B-stage of vulcanisation.
When the polysiloxane is brushed on, the two hardening stages are successively carried out. If the polysiloxane is calender-coated, vulcanisation to stage A is carried out during the calender-coating operation, and is followed by vulcanisation to stage B.
The covering of the textile material, which is present in a single surface form, and the applied layer of the flame resistant polysiloxane are applied to the core of plastics material in the usual manner, so that the preparation steps which were hitherto necessary for applying an additional layer between the core of plastics material and the covering are no longer necessary.
An embodiment of the present invention will now be described in more detail, by example only, with reference to the accompanying diagrammatical drawings which shows a section through part of an aircraft seat.
The aircraft seat which is shown in the drawing and which is indicated genrally by the reference numeral 10 has a core of plastics material 16 which may consist of, for example, of a polyurethane foam, If required, this core of plastics material 16 may be held in the desired shape and position by a support (not shown).
The outside of this core of plastics material 16, which is already in the shape of an aircraft seat 10, is provided with a coating of a conventional covering 12 of a textile material and a layer 14 which is closely connected to the coating 12, the layer 14 comprising a flame-resistant polysiloxane.
The layer 14 of the flame resistant polysiloxane is brushed or calender-coated onto the inside of the covering 12 of the textile material, the vulcanisation of the polysiloxane to stage A and to stage B taking place in two successive stages.
The composition of the polysiloxane which is preferably used may be taken from European Patent Application No. 0051212 (Bayer AG). This flame resistant polysiloxane comprises a diorganopolysiloxane, finely-divided silica and/or other fillers, finely-divided titanium dioxide, platinum, and a hardener and a nitrogen compound.
If the polysiloxane is brushed onto the covering in an unvulcanised form, the two vulcanisation steps to stage A or B have to be subsequently carried out.
When the polysiloxane is being calender-coated vulcanisation to stage A is carried out during the calender-coating operation; vulcanistaion to stage B has then to be subsequently carried out in the conventional manner.
