Abstract
This device comprises two coaxial elements mounted rotatably with respect to a spring, and two seats for positioning the spring. Each seat comprises a dorsal pivot projection configured in two coaxial elements. The pivot projection is delimited by a cylinder portion whose section is a first circular arc whose tangent forms an angle α with the axis of the spring. The section of each receptacle is formed by a second circular arc, having the same center and radius of curvature as the first circular arc, the tangent of which forms with the axis of the spring an angle γ greater than α. The pivot axes are parallel to one another at a distance L, and are included in a plane located at a distance R from the rotation axis. The maximum deflection angle of the device is δ. γ is within the range [arctg(L/2R)−δ/8 to arctg(L/2R+δ].
