Abstract
Saddle made of composite material, in particular for a bicycle, which comprises a support structure (2) provided with a padding (3) having, associated above it, a seating surface (7). The support structure (2) comprises a plurality of first layers (8) of high-rigidity composite material having an opening (11) formed centrally wherein and a second layer (9) of composite material with a rigidity less than that of the first layers (8), fixed to the latter along a superimposed surface covering the opening (11) so as to form an elasticaly yielding zone which is preferably located in the prostatic and ischiatic zones of the seat (7) of the saddle (1).
Claims19
Saddle made of composite material, in particular for a bicycle, of the type comprising a support structure (2) provided with a padding (3) having, associated above it, a seating surface (7), characterized in that said support structure (2) comprises at least one first layer (8) of composite material and at least one second layer (9) of composite material having a form different form that of said first layer (8) and fixed thereto along a superimposed surface (10) of said layers, to define portions with varying rigidity on said support structure (2).
Saddle made of composite material according to any one of the preceding claims, characterized in that said first layer (8) is made from a high-rigidity composite material and in that said second layer (9) is made from a composite material with a rigidity less than that of said first layer 18).
Saddle made of composite material, in particular for a bicycle, of the type comprising a support structure (2) provided with a padding (3) having, associated above it, a seating surface (7), characterized in that said support structure (2) is obtained by means of a plurality of differently formed superimposed layers (8) of composite material fixed together along superimposed surfaces (10), said layers (8) defining at least one elastically yielding zone formed by a smaller number of said superimposed layers (8).
Method for the manufacture of a saddle made of composite material, in particular for a bicycle, of the type comprising a step involving moulding, in a mould, of a cover (3) made of expanded elastomer material on top of a support structure (2), characterized in that it comprises the following operating steps:
- first hollow-punching of one or more first layers (8) of fabric consisting of high-rigidity composite material, defining substantially the profile of the support structure (2);
- formation of at least one opening (11) inside said first layers (8);
- second hollow-punching of at least one second layer (9) of fabric consisting of composite material with a rigidity less than that of said first layer (8);
- superimposition of said first layers (8) and said second layer (9) inside a mould;
- moulding and fixing of said first and second layers (8, 9) inside said mould by means of a thermosetting resin.
