| 摘要 |
The invention relates to a knee orthosis comprising two parts, upper (6) and lower (7), each provided with at least one attachment means (8, 9) linking supporting parts (25, 25'), suitable for attaching said upper (6) and lower (7) parts respectively to a thigh and to a leg, wherein both of said parts (6, 7) are linked via bi-centric articulation means (10, 11) suitable for enabling each of said parts to pivot about a common axis (16, 16') between the ends of the supporting parts (25, 25') and an intermediate part forming a connection rod. Said orthosis comprises a cord (12) linking the common axis between the connection rod connecting an articulation means (11) to the upper portion of the orthosis, with the distal end of an arm forming one of the supporting parts (25') of the lower portion (7) of the orthosis. The length of said cord is determined such that the cord exerts a given traction on the attachment points of the two ends of the cord when the upper (6) and lower (7) portions are pivoted in relation to one another so as to stretch toward the alignment of the axes thereof (X1, X2). |
