Patent ID: 8105255

Claim:
An orthosis for the correction of the position of a two-jointed body joint extending across the two body parts ( 5 , 30 ) interconnected by the body joint, the orthosis being provided with first and second arms ( 7 , 8 ), which are held in position on the body parts ( 5 , 30 ) by a respective fastening means ( 3 , 4 ) and are interconnected by a pivot joint ( 6 ) adjacent to the body joint, the pivot joint ( 6 ) being formed by a central adjusting ring ( 12 ) bordered by the first and second arms ( 7 , 8 ) for bending the body parts ( 5 , 30 ) necessary for normal movement, said pivot joint comprising: an axle ring ( 14 ) being coaxial with respect to the central adjusting ring ( 12 ) for one arm; and a ring bearing ( 13 ) being eccentric with respect to the axle ring ( 14 ) for the other arm, the rotational plane ( 15 ) of which is pivotable with respect to the rotational plane ( 16 ) of the axle ring ( 14 ) by rotating the central adjusting ring ( 12 ) in such a way at such an angle that the arm ( 8 ), supported by the ring bearing ( 13 ) and in conjunction with the body part ( 30 ) retained by it, assumes a pivoting position of this body part ( 30 ) as opposed to the stretched normal position, depending on the rotation angle on the central adjusting ring ( 12 ) in relation to the first arm ( 7 ) connected to the axle ring ( 14 ); wherein the central adjusting ring ( 12 ) has a rotationally fixed connection with an end plate ( 35 ) covering the ring bearing ( 13 ) toward the outside, via a coupling ( 18 , 19 ) feeding through the ring bearing ( 13 ), said end plate ( 35 ) allowing the adjustment of the rotational plane ( 15 ) the second arm ( 8 ) to the rotational plane ( 16 ) of the first arm ( 7 ), wherein the ring bearing ( 13 ) includes a single projection ( 34 ) facing said end plate ( 35 ), the projection ( 34 ) having a peripheral side having a semi-circular portion and a flat section ( 18 ), the coupling ( 18 , 19 ) being formed by the flat section ( 18 ) on the peripheral side of the projection ( 34 ) which matches a flat part ( 19 ) of the end plate ( 25 ).
