Abstract

DISPOSITIVO DE REGULACION DE LA TENSION DE LA CAPA DE APOYO DE UN ASIENTO, CONSTITUIDA POR UNA CAPA DE RESORTES (6,7) DE TENSION REGULABLE DISPUESTA ENTRE DOS ELEMENTOS OPUESTOS (3,4) DE UN ARMAZON (1). SE CARACTERIZA PORQUE LA CAPA DE RESORTES (6,7) SE UNE A UNO (3 O 4) DE LOS ELEMENTOS DEL ARMAZON POR UN MATERIAL CON MEMORIA DE FORMA (10) A FIN DE OBTENER UN INCREMENTO DE LA TENSION DE LA CAPA CUANDO ESTE ES LLEVADO, POR CALENTAMIENTO, A UNA TEMPERATURA DETERMINADA, EN ASOCIACION CON UN DISPOSITIVO DE BLOQUEO (13), EN ESPECIAL PARA CONSERVAR DICHO INCREMENTO DE LA TENSION AL PRODUCIRSE LA SUPRESION DE DICHO CALENTAMIENTO.DEVICE FOR REGULATING THE TENSION OF THE SUPPORT LAYER OF A SEAT, CONSISTING OF A LAYER OF SPRINGS (6,7) OF ADJUSTABLE TENSION ARRANGED BETWEEN TWO OPPOSING ELEMENTS (3,4) OF A FRAME (1). IT IS CHARACTERIZED BECAUSE THE SPRING LAYER (6,7) IS JOINED TO ONE (3 OR 4) OF THE ELEMENTS OF THE FRAME BY A MATERIAL WITH MEMORY OF FORM (10) IN ORDER TO OBTAIN AN INCREASE IN THE TENSION OF THE LAYER WHEN THIS IT IS TAKEN, BY HEATING, TO A CERTAIN TEMPERATURE, IN ASSOCIATION WITH A LOCKING DEVICE (13), ESPECIALLY TO KEEP SUCH INCREASE OF THE TENSION WHEN THE SUPPRESSION OF SUCH HEATING OCCURS.
