US Patent 10161174 Vehicle having a braked sliding door

A vehicle has a sliding door fitted with a rotatable brake member to apply a braking force to the sliding door when the vehicle is on a slope. The brake member is automatically rotated about a pivot axis X-X by a moveable member forming part of an actuator when the vehicle is resting on a slope into a position in which a braking force is applied to the sliding door by the interaction of the brake member with an elongate track in the form of a sliding door support track.
