The invention discloses an active protection safety belt applied to automobile safety 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; and the external diameter of the narrowing section gradually decreases along a downward vertical direction of the air inlet. During quick changes of driving vehicle states, the safety belt and an air pump connected with a vehicle driving safety system start to work and directly inflate the air sac; 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.
