ABSTRACT:
An automatic seat belt system makes use of a drive member, for example, a drive tape for causing a runner to move back and forth along a guide rail mounted from the side roof to the center pillar within the room of an automobile. The drive tape is formed of a stretched tape made of a polyamide resin such as nylon 11 or nylon 12. The drive tape requires a low material cost and exhibits superb resistance to tensile and compression forces. The former advantage enables to reduce the overall manufacturing cost of the automatic seat belt system. On the other hand, the latter advantage permits use of a narrower and thinner drive tape, whereby permitting an overall size reduction to the automatic seat belt system. Owing to the possibility of using such a narrow drive tape, the drive tape can be arranged in a state bent in its widthwise direction without increasing its sliding resistance to any substantial degree.
