Patent ID: 8851497

Claim:
A support for bicycle saddle, comprising: a support rod, connected, at an upper part thereof, to the saddle and engaged slidingly in a lower support element, rigidly fixed or integrally shaped by a bicycle frame; an actuator member suitable to exert a thrust force on the rod in an axial direction, said actuator member being housed internally to said bicycle frame, in a lower part with respect to the rod; a blocking member, associated with said lower support element and suitable to fix a position of said rod in a configuration chosen by a cyclist, said blocking member comprising a tilting body pivoted on an eccentric longitudinal axis, said body being suitable to rotate about said eccentric longitudinal axis between a first blocking position, wherein a surface of said tilting body is in contact with said rod, at a contact surface of said rod, through an opening in said lower support element, and a second disengagement position, wherein the surface of said tilting body is spaced from said rod, said blocking member further comprising an actuator means for exerting a stress at said eccentric longitudinal axis, in order to take and keep said tilting body in the first blocking position, said contact surface comprising a curvilinear profile having a varying radius of curvature, said surface comprising a first lower portion, located under a substantially horizontal plane passing by said eccentric longitudinal axis when said tilting body is in said blocking position, said first lower portion having a curvilinear profile having a constant radius of curvature, said surface comprising a second upper portion, located above the substantially horizontal plane passing by said eccentric longitudinal axis when said tilting body is in said blocking position, said second upper portion having a curvilinear profile having an increasing radius of curvature.
