Method for producing headrest of motor vehicle seat, involves attaching detection workpiece with structure, where workpiece and armature are indexed with respect to mold after expansion of foam to obtain headrest

摘要

The method involves providing an armature (1) comprising two legs (2), and providing a structure (4) with an interlocking unit of the armature. A mold (14) is provided with two channels of a passage that branches outwardly for forming an indexing unit (17) of a frame with respect to the channels of the mold. A mixture is injected into a cap (8) resiliently compressible foam precursor. A detection workpiece is attached with the structure, where the workpiece and the armature are indexed with respect to the mold after expansion of the foam to obtain a headrest.
