Abstract
The disclosure relates to an electrically heated vehicle seat (1) with cover fabric portions (5,6), heating element (7) and padding (4) sewn together with a plurality of first seams (11-16 and 21-26) and second seams (10,19,20,29). The heating element has heating portions separated from each other by the first seams and communication portions which electrically connect to each other the heating portions which have been separated by the first seams. The first seams are sewn through the heating element without crossing the heating portions or communication portions. The second seams are not sewn through the heating element and neither are they sewn through the padding.
The disclosure also relates to a method of manufacturing an electrically heated vehicle seat, where cover fabric portions are sewn together with the heating element and padding using a plurality of seams. First seams are sewn through cover portions, heating element and padding, such that they do not cross the heating portions or communicaton portions in the heating element. Second seams are sewn solely through cover portions so that they cross or extend adjacent to the first seams in the vicinity of their ends.
