摘要

The invention relates to a method for making a seat element from a portion of upholstery (1) comprising a covering layer made of a relatively compact plastic material, a network formed by a continuous layer-structure of metallic springs (5) whose intermeshed coils are, on one side, substantially flush against the lower face of the cover (1) and an intermediate linking layer (3) made of a foam of plastic material partially embedding the coils of the layer-structure of springs (5). …??According to the invention, the peripheral border (7) of the said upholstery portion is clamped in a mould (11) to be injected, this mould having a cavity (9) into which the said border (7) penetrates, a thermoplastic material with an added foaming agent is injected under low pressure into the said cavity and this thermoplastic material is allowed to cure therein. …IMAGE…
