Opening and closing system for a motor vehicle sliding door

Abstract

Opening and closing system for motor vehicle sliding door, which can be displaced along guide rails between an open position and a closed position, with a brake device for braking the sliding door. The brake device is designed in such that it is activated automatically during displacement of the sliding door when a collision state is indicated or signaled or exists during opening and/or when a jamming state is indicated or signaled or exists during closing (pre-crash situation). The opening and closing system can thus react without any time delay to a jamming or collision state and can rapidly brake the displacement of the relatively heavy sliding door. At the same time or with a time offset, a drive motor for the motorized movement of the sliding door can be braked and/or reversed. The opening and closing system can be used both for manually operated and automatic sliding doors.
