ABSTRACT:
The disclosed gelatinous cushion comprises a gelatinous material enclosed in a membrane fixed to a support. The membrane has at least one told and the gelatinous material assumes the shape of the fold. The fold is arranged in such a way that the membrane unfolds when pressure is exerted on the cushion. Advantages: the elimination of the membrane effect due to the compression of the gelatinous material in the membrane, the improvement of wearing comfort and of dampening properties. Application in particular to the making of highly comfortably nose-pads for eyeglass frames.
