Seat cushion fabrication method for motor vehicle, involves closing lid such that washer is supported on periphery of orifice, injecting mixture of compressible foam into molding space, and demolding seat cushion after expansion of foam

摘要

The method involves providing a foam based sealing washer (8) that is made of elastically compressible material. A section of a hole (9) in the washer is similar to a free end of a molding stud of a lid and to a peripheral envelope encompassing a ventilation orifice (5). The washer is enforced on the free end of the stud. A barrier material (2) is placed in a tank. The lid is closed such that the washer is supported on a periphery of the orifice. A primer mixture of compressible foam is injected into a molding space. A seat cushion (1) is demolded after expansion of the foam.
