Process and supporting mould for producing bolsters, in particular head rests for motor vehicle seats, by foam-filling bag-like bolster coverings

摘要

In the foam-filling of prefabricated bolster coverings (13) for the production of bolsters (6), which may contain insert parts (10) if appropriate, in order to avoid soiling of the bolster covering (13) by foam from the outside, use is made of a clamping plate (9), which is fastened on the inside on a tie rod (8), which is led through the cover (4) of a supporting mould (1) and is designed as a threaded spindle (8), while on the outside there is arranged a clamping piece (17), which is designed as a threaded nut (17) and has a hand lever (16) for securely clamping, as a result of which the edge (15) of the opening (12) of the bolster covering (13) can be clamped in a sealing manner between the cover (4) and clamping plate (9). <IMAGE>
