Abstract

UN DISPOSITIVO PARA INCORPORARLO EN EL RESPALDO DE UN ASIENTO, PARA PROPORCIONAR UN SOPORTE LUMBAR AJUSTABLE, QUE CONSTA DE UN ELEMENTO DE PLATAFORMA (3) SUSPENDIDO POR UNOS RESORTES TENSORES (2) EN UN ARMAZON DEL ASIENTO (1) PARA SOPORTAR LOS COJINES DE UN RESPALDO. EL ELEMENTO DE PLATAFORMA (3) TIENE UNOS RIELES LATERALES ALARGADOS (5,9) ENTRE LOS CUALES SE EXTIENDEN UNOS ALAMBRES TRANSVERSALES (10) QUE PROPORCIONAN EL SOPORTE DE PLATAFORMA. ENTRE LAS PORCIONES RESPECTIVAS DE CADA UNO DE LOS RIELES (5,9) HAY UNIDO UN ALAMBRE TIPO BOWDEN (21) PARA APLICAR UNA FUERZA DE COMPRESION LONGITUDINAL, LO QUE HACE QUE LOS RIELES (5,9) SE ARTICULEN HACIA AFUERA HASTA UN PUNTO DE ARTICULACION (150) PARA VARIAR EL SOPORTE LUMBAR PROPORCIONADO POR LOS ALAMBRES TRANSVERSALES (10).
