Seat belt webbing and passenger-holding device using it

摘要

A seat belt webbing has an elongation at initial yield point of 6 % or less, tenacity at 8 % elongation of 1.5 to 7 kN, tenacity at break of 15 kN or more, elongation under load of 11.1 kN of 10 to 40 % and an energy absorption work amount of 600 J/m or more. A passenger-holding device comprises the seat belt webbing and a seat belt retractor portion having a lock mechanism for stopping rotation or a take-up shaft in response to acceleration or abrupt unwinding of a webbing.
