Seat belt device for motor vehicle for retaining occupant during accidents, has seat belt provided with section that is rollable on retractor at end of belt, where section is formed from material with higher tensile strength than seat belt

摘要

The device (1) has a flat seat belt (7) provided with a section (6) that is rollable on a retractor (4) at an end of the seat belt, where the end is turned toward the retractor. The section is formed from a material with a higher tensile strength than the seat belt, where length of the section is measured such that the section does not come into contact with an occupant when the occupant wears the seat belt. The section exhibits a circular cross-section area, where aspect ratio of the seat belt to the section is approximately 2:1.
