A hip joint for orthopedic orthesis comprising a pelvic attachment (2) to which the tops of two arms (3) are articulated, and in which the arms (3) are adapted to be rigidly coupled to the top of respective thigh-leg-foot braces and are provided with respective hip locking devices (23) that can be disengaged manually to allow the patient to sit; two bushes (6) having substantially vertical axes are fixed laterally to the pelvic attachment and two shafts (10) are articulated to the bushes (6); the arms (3) are articulated to the shafts (10) in a downward region about substantially horizontal axes; the arms are provided with elements (20,21) for kinematic connection to the bushes (6), so that each torsion of the shaft (10) with respect to the bush (6) is matched by a rotation of the arm (3) with respect to the shaft (10); and the arms are connected by motion transmission elements (31,32) adapted to complementarily transmit the rotation-torsion movements from one arm to the other.

Abstract
A hip joint for orthopedic orthesis comprising a pelvic attachment (2) to which the tops of two arms (3) are articulated, and in which the arms (3) are adapted to be rigidly coupled to the top of respective thigh-leg-foot braces and are provided with respective hip locking devices (23) that can be disengaged manually to allow the patient to sit; two bushes (6) having substantially vertical axes are fixed laterally to the pelvic attachment and two shafts (10) are articulated to the bushes (6); the arms (3) are articulated to the shafts (10) in a downward region about substantially horizontal axes; the arms are provided with elements (20,21) for kinematic connection to the bushes (6), so that each torsion of the shaft (10) with respect to the bush (6) is matched by a rotation of the arm (3) with respect to the shaft (10); and the arms are connected by motion transmission elements (31,32) adapted to complementarily transmit the rotation-torsion movements from one arm to the other.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
