Silent, rattle-free passive seat belt system

摘要

A passive seat belt system is constructed of a guide rail, a slider movable along the guide rail, a webbing, a drive member for driving the slider, a bushing for connecting the drive member and slider in a state maintained in contact to each other with a gap left between the drive member and guide rail at the position of the bushing and on a side opposite to the slider, and contact members provided on the drive member with the bushing interposed therebetween. The contact members are in contact with the guide rail on a side opposite to the slider. Instead of the bushing and contact members, a cam may be provided between the drive member and slider for causing the slider to move in a direction away from the drive member when the drive member moves in a longitudinal direction.
