Abstract: The invention addresses the basic problem of providing a lifesaving means 1 for a life jacket RW, wherein said life jacket offers a higher degree of buoyancy in an emergency. This is achieved in principle by inserting an additional lifesaving means 1 into a life jacket RW and activating the additional lifesaving means 1 via sensors S in conjunction with a control unit 9 or by manual actuation, such that the buoyancy is greater overall than that of the life jacket RW itself. Buoyancy that is reliable in an emergency is present if the body of a person can be kept above water without additional movement by the person. Depending on the clothing worn, the buoyancy is greater than 150N. Triggering preferably occurs automatically.
