Title
(EN) PROCESS FOR PRODUCING MOTOR VEHICLE SEAT CUSHIONING
(FR) PROCÉDÉ DE RÉALISATION D'UNE MATELASSURE DE SIÈGE DE VÉHICULE AUTOMOBILE
Abstract
(EN)
The invention relates to a method for creating a motor vehicle seat cushion, the said method providing a cover comprising a format (2) of a complex comprising a layer of covering material (3) and a sublayer of elastically compressible foam (4), and arranging on the said sublayer a film (8) based on thermoplastic polyurethane, the said film having a melting point and a melt mass-flow index such that it breaks down under the action of the heat released during the formation of the foam, the said film being provided with a reinforcing thin-film (11) so as to form a two-layer barrier against the penetration of foam, the said reinforcing thin-film being based on a thermoplastic polyurethane with a melting point higher than that of the said film and having a melt mass-flow index lower than that of the said film, so as to have greater strength than the said film so that its breakdown under the action of heat is delayed.
(FR)
L'invention concerne un procédé de réalisation d'une matelassure de siège de véhicule automobile, ledit procédé prévoyant une coiffe comprenant un format (2) d'un complexe comprenant une couche de matériau de revêtement (3) et une sous-couche de mousse (4) élastiquement compressible, et de disposer sur ladite sous-couche un film (8) à base de polyuréthane thermoplastique, ledit film ayant un point de fusion et un indice de fluidité en masse tels qu'il se dégrade sous l'action de la chaleur dégagée lors de la formation de la mousse, ledit film étant pourvu d'une pellicule de renfort (11) de manière à former une barrière bicouche d'entrave à la pénétration de mousse, ladite pellicule étant à base de polyuréthane thermoplastique de point de fusion supérieur à celui dudit film et d'indice de fluidité en masse inférieur à celui dudit film, de manière à présenter une résistance accentuée par rapport audit film pour se dégrader de façon retardée sous l'action de la chaleur.
