ABSTRACT:
A saddle includes a body of thermoplastic material constituting a load-bearing structure on which a padding of expanded plastics material is fitted. The padding is made of an ethylene vinyl acetate copolymer which does not require the application of a covering layer. The padding is formed by injection moulding and allowed to expand to a size larger than the final size. The padding is then placed on the load-bearing structure and is firmly coupled to the load-bearing structure upon cooling and shrinking.
