Abstract
A method performed by a retraction control system of a vehicle for controlling refraction of a seat belt of a reversible seat belt refractor arrangement for a vehicle occupant is provided. The control system determines fulfillment of an activation condition based on an initiating input derived from a vehicle situation sensing system, which initiating input indicates that the vehicle, at an initiating time instant, is considered likely to be, or is about to become, involved in a hazardous situation and/or uncomfortable dynamic situation. The control system generates an activation signal utilizable for initiation of retraction of the seat belt. If the control system determines absence of fulfillment of a confirming condition within a predetermined confirming time period, and/or if the control system determines fulfillment of an abort condition within a predetermined abort time period, the control system generates a deactivation signal utilizable for aborting the initiation.
