Abstract

SE PROPORCIONA UN APARATO PARA AJUSTAR LA POSICION DE UN RESPALDO (24) EN RELACION A UN ASIENTO (20) DE SILLA. EL RESPALDO (24) INCLUYE UNA CAÑA (30) ALARGADA QUE TIENE UNA PORCION (32) INFERIOR CURVADA. PREFERIBLEMENTE, UN MUELLE (58) MANIOBRABLE ENGANCHA LA CAÑA (30) PARA INCLINARLA EN UNA DIRECCION HACIA ARRIBA. UN ALOJAMIENTO (28) ESTA ADAPTADO PARA RECIBIR DESLIZABLE LA PORCION (32) CURVADA DE LA CAÑA (30) Y CONDUCIR EL MUELLE. UN MECANISMO DE ALDABA (62, 34) ESTA ADAPTADA PARA ENGANCHAR LA CAÑA (30) PARA BLOQUEAR EL RESPALDO (24) EN UNA POSICION DESEADA, Y UN MIEMBRO ACTUADOR (66) ESTA ADAPTADO PARA MOVER EL MECANISMO DE ALDABA (62, 34) ENTRE UNA POSICION DE CONEXION Y DESCONEXION. EN OPERACION, EL MECANISMO (62, 34) DE ALDABA SE DESCONECTA PARA PERMITIR QUE LA CAÑA (30) DEL RESPALDO SE MUEVA EN UNA CAMINO CURVILINEO A UNA ALTURA DESEADA Y QUE CORRESPONDE A POSICION ANGULAR, Y SE RECONECTA PARA BLOQUEAR LA CAÑA (30) DEL RESPALDO EN DICHA POSICION.
