Abstract: It consists of continuous production of a woven or unwoven piece of textile fibers, to whose piece a layer that is going to be the middle one is affixed on the back surface. It is thick enough to offer resistance to the passing of a thermostable material that will be finally affixed to the same, wherein it will remain imbedded. The textile compound formed of the two layers referred to first of all, the second layer being an unwover layer, is subjected to a hot pre-forming process. Then it is inserted in a mold in which the thermostable material formed by a polyester-fiber glass mass is placed, hot pressing the whole and obtaining a rigid and resistance sheet-like body, whose visible surface is covered with the layer of textile compound that is highly resistant to vandalism.

Abstract: They improve the passenger's passive safety and comfort. They are comprised of a deformable frame to absorb the energy transmitted in the presence of an impact, without any portion of the same becoming detached. The design thereof has no sharp angles or edges and in the back there are perfectly inserted accessories. The footrest is also hidden without projecting, having blunt forms.The frame has two crossbars (6) secured to the side feet (4.) The chassis or bed of the seat is formed by two triangular side plates (8, 9) braced by two cylindrical bars (13) passing through cross members (7) welded to the crossbars (6.) The back (3) is hinged to the top angular area of these plates (8, 9) and is adjustable as its frame (12) has an extension (17) connected to an adjustment mechanism (19) with an automatic instant blocking system.Optionally, the seat on the aisle is shiftable.The headrest is cushioned in the back since the rear frame remains lower.
