摘要

The mechanism adjusts a bicycle saddle vertically, having an upright sliding in a saddle tube. There is a support (6) fixed to the top end of the tube (1), and which has a thruster (7) with an inclined face, moved by a lever (9) towards the axis of the upright. The inclined face bears against a complementary one on a slide (8), which also has a face bearing against the upright. The lever can be fixed to a cam (91a) acting against the thruster, moving it and the slide to and from the upright.
