<p>The device has a rear lateral attachment zone (54) with five rigidifying ribs (71-75) that separate six cavities (81-86), and a base plate (3). Flexion forces induced in the base plate are distributed along an opening (12) with respect to the ribs. Contours of the cavities include right portions and curved portions. The right portions delimit the ribs and the curved portions connect the right portions. The flexion forces are induced in the base plate between the attachment zone and an anchoring zone by the traction forces on a connection.</p> |
