    Abstract: A system for preventing sliding vehicle doors from opening during collisions is disclosed. The system includes at least one roller assembly of a sliding door connected to a guiderail on a vehicle body. The roller assembly includes a protruding member that interfaces with a protrusion engaging member attached to the vehicle body. During normal operation, the protruding member clears the protrusion engaging member. During a collision in which the sliding door is pushed laterally outwards, the protruding member contacts the protrusion engaging member and stops the outward motion of the sliding door. In some cases, a vehicle includes corresponding protruding members and protrusion engaging members for both an upper roller assembly and a lower roller assembly of a sliding door.

    Abstract: A large diameter portion is provided on one side of a closing side drum in an axial direction, a small diameter portion having a diameter gradually decreasing from the large diameter portion to the other side of the closing side drum is provided on the other side of the closing side drum, a partition wall disposed between adjacent small diameter cable grooves in the axial direction of the closing side drum to prevent a closing side cable from slipping out of the small diameter cable grooves is provided in the small diameter portion. Accordingly, the thick partition wall provided in the small diameter portion can reliably prevent the closing side cable from slipping out (derailing) from the small diameter cable grooves even when a winding position of the closing side cable on the closing side drum is changed and transferred from the large diameter portion to the small diameter portion.
