摘要 |
The invention relates to a shoulder mechanism for an orthosis, providing a ball type joint between a support and an orthosis upper arm, comprising a first intermediate element mounted to pivot on the support about a first pivot axis, a second intermediate element mounted to pivot on the first intermediate element about a second pivot axis, the upper arm being mounted to pivot on the second intermediate element about a third pivot axis. According to the invention, the first pivot axis extends in a longitudinal horizontal direction, the first intermediate element including a circular rail on which the second intermediate element slides and that presents a geometrical axis defining the second pivot axis that extends vertically when the upper arm is at rest, the circular rail extending to go around the shoulder on the outside.
