Abstract
A thread for sewing occupant protection devices includes a spun thread and a thermoplastic elastomer coating. The thread can be used to form a sewn seam joining two fabric panels together to create an airbag. The seam can create needle holes in the two fabric panels. The seam can be heated after assembly of the airbag, such that the thermoplastic elastomer coating displaces off of the spun thread and fills in any needle holes.
