Abstract
Un cojín neumático, caracterizado esencialmente por el hecho de que dos piezas de tejido, de cualquier forma, se recubren por la parte interior con un material plástico soldable, o caucho, u otro, formando un contorno pegado y unos tramos transversales igualmente soldados en la zona central, dando lugar, una vez hinchado, a un contorno uniforme comunicante con las cavidades del centro, lo cual da lugar a dos depresiones iguales por ambas caras del cojín y a un ligero almohadillado central, haciéndolo apto para la colocación de la cabeza, como almohada, o bien como asiento según convenga, comprendiendo un tubo válvula de llenado y tapón obturador de forma ensanchada.
