A harness type safety belt absorbs dropping shocks to a user who accidentally falls from an elevated position. If the user fails to apply a rope hook to a life line and falls from the elevated position, an air bag in a mounting body inflates to absorb the dropping shock to reduce the dropping impact applied to the user. If the user falls with the rope hook connected to the life line, the rope suspends the user. The body of the user is supported by a waist belt, shoulder belts and thigh belts. Therefore a tension applied by the rope to the body of the user is dispersed to each of the belts so the body of the user is stably supported.
