| 摘要 |
<p>The invention relates to a shoulder mechanism for an orthosis, permitting a ball-type articulation between a support (1) and an orthosis arm (100), comprising a first intermediate element (2) mounted so as to turn on the support about a first axis of articulation (A1), a second intermediate element (4) mounted so as to turn on the first intermediate element about a second axis of articulation (A2), the arm being mounted so as to turn on the second intermediate element about a third axis of articulation (A3). According to the invention, the first axis of articulation (A1) extends in a longitudinal horizontal direction, the first intermediate element having a circular rail (3) on which the second intermediate element (4) slides and which has a geometric axis defining the second axis of articulation (A2), which extends vertically when the arm is at rest, the cicular rail extending around the shoulder.</p> |
