The invention is composed of two permanent magnets facing the same two poles, so as to prolong the pressure when the leg is in the extended position, so as to avoid the change of knee weight, Since the weight will be supported by the knee to thigh press and the lower half of the tights, it is called the "bridge knee.". Each roller has four permanent neodimi magnets, 1.5 mm in diameter and 3.0 m in length.Located at both ends of the two rotators The magnets face the same poles to ensure that the tension in the active position is rejected (separated). Two permanent magnets lose space on the knee. The mechanical system is located on both sides of the knee. In the sujecion pocket, it can be external or internal. There is a device on the right and left of each knee. The space between the magnets is called the middle plate. The invention also includes a device driven by two voltages, which are combined in the non active position of the intermediate plankton,They grow in the position of long legs (straight lines), by their movement on their eccentric axis and through a slot.La presente invencion esta comprendida por dos imanes permanentes enfrentados a polos iguales logrando que los tensores se alarguen cuando la pierna esta en posicion extendida logrando asi evitar la accion del peso sobre la rodilla, ya que el peso sera soportado por la sujecion de la rodillera al muslo en la parte superior y por la corva en el extremo inferior, de ahi el nombre de "rodillera puente". Cada rodillera lleva cuatro imanes permanentes de neodimio de 1.5 centimetros de diametro y de 3 centimetros de largo, ubicados en los dos extremos de los dos tensores que lleva cada lado de la rodillera. Los imanes estan enfrentados a polos iguales para lograr la repulsion (separacion) de los tensores en la posicion activa. El sistema mecanico para la restauracion del espacio perdido en la rodilla por dos imanes permanente se ubica en los costados de la rodillera en bolsillos de sujecion que pueden ser ext
