Abstract: This invention relates to a process for manufacturing cushion and mattress elements made of supple, open-cell cellular matter, by casting into a mould, from a head ensuring mixture of at least two basic components, of the product thus formed; said mould is transferred from a preparation station where a demoulding agent is projected, to be presented beneath said head; the latter is displaced along a continuous path covering at least all the surface of the mould and at a speed ensuring, on the one hand, a uniform distribution of the product and, on the other hand, a total time of passage less than the maximum expansion time of the product projected at the beginning of this path; a cover is closed on said mould, and the latter is transferred towards standby stations where it remains thus for a time longer than that of maturing of the cellular matter obtained; the cushion element thus constituted is removed and the mould is transferred back towards the preparation station.

Abstract: The present invention elates to inflatable cells for cushion and mattress elements, and in particular for medical applications, the elements comprising a soleplate that has a bottom support surface that is plane plus said telescopic cells that extend perpendicularly from and that are fixed to said soleplate in a matrix that covers the top surface of the element, each cell being made out of a flexible material forming an airtight external skin that encloses an internal volume, each of which is in communication with the internal volume of at least one adjacent cell.
