The invention discloses an active safety belt structure comprising a safety belt. A compression cavity is disposed in the safety belt; an air sac is foldably arranged in the compression cavity; a slit is formed in one side of the safety belt; the end part of the air sac is provided with an air inlet; the air sac is formed by a wedging section and a narrowing section communicated with the wedging section; an end surface of the wedging section facing one side of the slit is inwardly recessed arc-shaped; the external diameter of the narrowing section gradually decreases along a downward vertical direction of the air inlet; one end of the slit close to a movable part of the safety belt is stitched via a stitching line; the main contact parts between the safety belt main body and the upper trunk are areas from the shoulders to the chest part and to the belly side; due to the structural characteristics of the belly side area, more soft tissues are provided and excellent buffering effect can be achieved; the wedging section is mounted on the upper end of the air sac and is adaptive to the contact parts; and injection damage to the contact parts by the middle of the air sac after collision can be prevented.
