Abstract:
A method for producing a bicycle saddle, comprising:(a) forming a rigid saddle base having a support region with a converging part and a diverging part, a lateral flange extending around the support region, a hole formed in the diverging part, a concave inner surface defined by the support region and the lateral flange, and a convex outer surface opposite to the concave inner surface;(b) placing the saddle base in a male mold including a projecting mold part with a surface which is contoured to substantially complement the concave inner surface of the saddle base, and an indentation formed in the surface of the projecting mold part, wherein the saddle base is positioned on the surface in such a manner that the lateral flange is entirely in contact with the surface and that a portion of the support region adjacent to the indentation is spaced from the surface;(c) placing a foam material in a female mold which has a mold cavity;(d) causing the projecting mold part to project into the mold cavity until the mold cavity is closed, and until the convex outer surface of the saddle base extends entirely in the mold cavity; and(e) forming a saddle cushion that covers entirely the convex outer surface of the saddle base by causing the foam material to expand and fill a space in the mold cavity around the projecting mold part and then fill the indentation through the hole in the saddle base.
