Title (EN) CUSHION MADE FROM PLASTIC FOAM
(FR) COUSSIN EN PLASTIQUE MOUSSE
Abstract:
(EN) The cushion consists of a wedge-shaped bottom portion (2) of plastic foam, which changes impression hardness and carrying capacity at fluctuating temperature and air humidity, and of a wedge-shaped top portion (1) of a soft, more porous plastic foam, which from the backwardly inclined front surface (3) shows decreased thickness towards the rear edge of the cushion. A large number of through-going holes extending from the top surface of the cushion unto its under surface are functioning as ventilating channels which impede the formation of a moist environment and of local heating. The cushion is suitable for impeding the development of pressure sores and is in particular intended for cushions used in wheelchairs.
(FR) Le coussin décrit se compose d'une partie de dessous en forme de coin (2) en plastique mousse dont la dureté au contact et la capacité portante varient avec les fluctuations de la température et de l'humidité de l'air, ainsi que d'une partie de dessus en forme de coin (1) en plastique mousse mou plus poreux dont l'épaisseur décroît depuis la surface antérieure inclinée vers l'arrière (3) en direction du bord postérieur du coussin. Un grand nombre de trous traversants s'étendant de la surface de dessus du coussin jusqu'à sa surface inférieure servent de conduits de ventilation, qui empêchent la formation d'une atmosphère humide et d'un réchauffement local. Un tel coussin sert à empêcher la formation sur la peau des escarres dues à la compression des tissus et il est notamment conçu pour être utilisé avec des fauteuils roulants.
