<p>The present invention relates to a device, a method and a motor vehicle comprising said device and/or method for belt tightener activation in a vehicle in rollover accidents. The device according to the present invention comprises a device for activating at least one belt tightener (102) in a safety belt system (101) in a vehicle(100), such that said vehicle (100) comprises at least one sensor element (103) to monitor and transmit data (104) containing information about the drivability of a region (108) in front of the vehicle to a calculation unit (105) situated in the vehicle (100), the vehicle comprises at least one tilt sensor (106) to receive and send data containing information about the vehicle's lateral tilt (107) to the calculation unit (105), and the calculation unit (105) is adapted to send a signal to the safety belt system (101) to activate the belt tightener (102) when the vehicle's angle of lateral tilt (107) exceeds a predetermined value (a, b). A distinguishing aspect of the invention is that said predetermined value (a, b) is represented by a first value (a) if said drivability data indicate no increased rollover risk to the vehicle (100) and by a second value (b) if said drivability data indicate an increased rollover risk to the vehicle, the second value (b) being smaller than the first value (a).</p> |
