Abstract

An intermediate electrical connecting apparatus (14) for a seat-heating system (10) includes a first junction (48) and a second junction (50). The first junction (48) is electrically coupled to a first heating element segment (30) of a heating element (18). The second junction (50) is electrically coupled to a second heating element segment (32) of the heating element (18). A seam segment (52) is electrically coupled between the first junction (48) and the second junction (50) and includes a plurality of redundant electrically conductive connections (54), which have a spacing arrangement therebetween.
