• the shells 10, 1 1 surround the buttocks following the pedaling movement. It is emphasized that it is necessary to form a suitably shaped surface conforming to the region of the ischium and the upper part of the femur, and for this section views and scale drawings are given in Figures 8, 9 , 10.
• the support cups 10, 11 certainly provide the transverse and longitudinal resistance of the cyclist's pelvis, but not the freedom of movement. Moreover, because of this freedom of pivoting, these cups 10, 11, pivoting, create instability for the pool.
• the movement of the thighs necessarily produces a movement of leverage and lifting of the back part of the buttocks, when the thigh goes down. It is therefore a movement of up and down imposed on the pelvis that goes against the stable behavior of it and is particularly a source of fatigue.
• document PCT / EP94 / 00284 describes a saddle composed of two bearing surfaces in the form of abutments curved from front to back to surround the contour of the gluteus maximus muscles.

• the support contours formed by the edge of cavities or orifices receiving locally the ischions ensure by embedding good adhesion to the saddle.
• the slightly inclined forward and down position promotes ischial adherence to the saddle and gives more efficiency to pedal stroke by putting the gluteal muscles, those of the thigh and those of the hock, in optimal position of tension.

• the invention develops a saddle which, although said "bike saddle” is a seat used in many applications requiring a sitting position. While the lateral portions of the known saddles extending transversely of the elongate central portion have a transverse convex shape, they are replaced by two lateral supports in the form of independent support contours whose shape does not correspond to any convex transverse shape because the cross-section saddle support contours according to the invention is slightly concave upwards and inclined forwardly.
• the saddle according to the invention is perfectly adapted to the morphology of the human body, both for a stationary position and for a dynamic position, the support contours being the surfaces by which the body can rest comfortably without hindering muscular work during pedaling.

• the saddle avoids intercrural friction and its disadvantages and promotes the effectiveness of the pedaling gesture by eliminating any friction of the saddle with the inner thighs.
• the saddle offers a fixed, stable and solid support (bone) to the pelvis of the cyclist where the muscles going to the thigh leave.
• the saddle allows a total freedom of movements and thus a better mechanical performance of the pedaling while setting the pelvis. As the gluteal muscles are outside the bearing areas of the ischia, they are totally free.
• the branches constituted by blades are a particularly simple embodiment since they are advantageously the extensions of the support, itself connected by an attachment (adjustable) to the frame of the bike.
• the branches are advantageously blades connected to the support by a bent portion which gives each blade a certain flexibility, independent of that of the other blade, allowing excellent shock absorption.
