PURPOSE:To minimize the travel of a belt in the longitudinal direction of an elongated hole and to accomplish smooth operation of a winder by forming curved portions at both end portions in the longitudinal direction of the elongated bole of an outlet for a passive seat belt, which is disposed at the lower portion of a door, and forming a circular arc portion at both ends of the outlet. CONSTITUTION:A passive seat belt includes winders for the seat belt, disposed at the upper and lower portions of a door to freely take up the seat belt, wherein the middle portion of the belt is supported by a car body floor, and an outlet 61 for guiding the seat belt 3 is provided on the winder 2 disposed at the lower portion of the door. The outlet 61 has a linear portion 611 inclined about 30 deg. with respect to the vertical line not to cause a large twisting when the belt is installed at the waist of a crew, curved portions 612, 613 formed at both end portions thereof in the longitudinal direction and circular arc portions 614, 615 formed at both ends thereof. At the time of drawing out the belt, the travel of the belt in the longitudinal direction of an elongated hole of the outlet is minimized to prevent the belt from being caught by both end portions of the elongated hole, so that the winder can be smoothly operated. |
