  • the adjustment device may comprise a rotary part integral with the stop, the rotary part being able to rotate, between the first position and the second position, around the compression axis.
  • the rod can be elastically flexible. Thus, it can stiffen rather than block the elastic joint when the rotation of the rod is restricted in the first position of the stop of the adjustment device. Furthermore, the rod can be curved. Configured in this way, it can in particular at least partially bypass the compression spring, to be arranged therein compactly, without enlarging the imprint of the flexible element in a plane perpendicular to the compression axis and without interfering with compression. of the compression spring.
  • the compression spring can in particular be helical.

  • the adjustment device can act simultaneously on the stiffness of several compression springs.
  • two rods of the plurality of mechanisms can be connected by a joint.
  • This articulation can in particular comprise a flexible sleeve receiving respective ends of the two rods.
  • the flexible sleeve can in particular be split in order to facilitate its bending.
