<P>PROBLEM TO BE SOLVED: To provide a seat belt which is spread along a width and then expanded by injecting a liquid. <P>SOLUTION: The seat belt has a bag part 114 formed in a bag shape, and the bag part 114 has a brittle part 115 to be broken as its internal pressure rises; and the liquid is injected into the bag part 114 to cause a rise in internal pressure, and the brittle part 115 is then broken to widely spread a belt body 11. Further, the seat belt includes means 12 of injecting the liquid, and the belt body 11 has a one-side part 111, a center part 112, and an other-side part 113 in order in a spread state; and the one-side part 111 and other-side part 113 are folded inward toward the center part 112 in an unspread state to be made narrower, the bag part 114 is formed while being surrounded with the one-side part 111, other-side part 113 and center part 112, and the one-side part 111 and other-side part 113 are bound together at ends in a width direction to constitute the brittle part 115. <P>COPYRIGHT: (C)2013,JPO&INPIT |
