Abstract: Saddle made of composite material, in particular for a bicycle, comprising a support structure provided with a padding having a seating surface. The support structure comprises a plurality of first layers of high-rigidity composite material having an opening formed centrally therein and a second layer of composite material with a rigidity less than that of the first layers, fixed to the latter along a superimposed surface covering the opening so as to form an elastically yielding zone which is preferably located in the prostatic and ischiatic zones of the seat of the saddle.

Abstract: A ventilated support structure for a vehicle, such as a bicycle, comprising an upper side having a seat surface which is supported on a rigid or semi-rigid frame on which is anchored elastically flexible padding there between. The support structure may further comprise an aperture in an anterior portion of the frame. The aperture may be oriented at least partly in a direction of forward travel of the vehicle. An air distribution channel is connected to the aperture and is also connected to a plurality of air discharge openings to ventilate the seat surface.

Abstract: A method for manufacturing integral elastic supports formed by an upper covering (2), by an intermediate filler (3) and by a semirigid shell (4) entails the use of a mold with a hollow lower part, a flat upper part, and at least one intermediate plate. The method includes the following steps: opening of the mold; deposition on the lower part of a covering sheet with an excess border; securing of the excess border by means of the locking plate; deformation of the covering sheet in vacuum; pouring of a first layer of a gel compound in the fluid state; coupling of a semirigid shell to the upper part of the mold; pouring of a second layer of an expandable resin in the fluid state; closing of the mold; opening of the mold and removal of the finished support.
