A cargo restraining system for a vehicle comprising an extended flexible structure movably connected to a positioning arrangement, wherein the flexible structure is adapted for holding cargo arranged on a cargo floor of a vehicle cargo compartment in position in relation to the cargo floor, wherein the flexible structure is sized to cover at least a part of the cargo floor, wherein the positioning arrangement is adapted for enabling movement of the flexible structure between a storage position (P ST) and a load securing position (P LS), wherein in the storage position (P ST) the flexible structure is adapted to be positioned on a first height from the cargo floor, wherein in the load securing position (P LS) the flexible structure is adapted to be positioned on a second height from the cargo floor, wherein the first height is different from the second height, wherein the positioning arrangement comprises two or more holding devices (5a,5b,5c,5d), wherein a positioning member (16a,16b,16c,16d) is movably connected to each holding device (5a,5b,5c,5d), wherein the flexible structure at different positions along an outer periphery comprises two or more connection members (6a,6b,6c,6d), wherein each connection member (6a,6b,6c,6d) is adapted to be connected to a corresponding positioning member (16a, 16b, 16c, 16d), wherein each positioning member (16a,16b,16c,16d) is connected to an actuator, wherein the actuator is adapted for moving each positioning member (16a,16b,16c,16d) in relation to the corresponding holding device (5a,5b,5c,5d) for positioning the flexible structure between the storage position (P ST) and the load securing position (P LS), wherein each positioning member (16a,16b,16c,16d) is connected to the actuator via a wire structure, wherein each wire structure is adapted for displacing the corresponding positioning member (16a,16b,16c,16d) in relation to the corresponding holding device (5a,5b,5c,5d) upon activation of the actuator, wherein when the actuator is pulling the wire structures, the positioning members (16a,16b,16c,16d) are moved in a direction downwards in relation to the holding devices (5a,5b,5c,5d) towards the floor structure, characterized in that each positioning member (16a,16b,16c,16d) is connected to the corresponding holding device (5a,5b,5c,5d) via a spring (10a,10b,10c,10d), wherein each spring (10a,10b,10c,10d) is adapted for displacing the corresponding positioning member (16a,16b,16c,16d) in relation to the corresponding holding device (5a,5b,5c,5d), wherein when the actuator is releasing the wire structures, the positioning members (16a,16b,16c,16d) are moved in a direction upwards in relation to the holding devices (5a,5b,5c,5d) towards a ceiling structure due to the forces exerted on the positioning members (16a,16b,16c,16d) by the springs (10a,10b,10c,10d). wherein the positioning arrangement is adapted for enabling movement of the flexible structure between a storage position (P ST) and a load securing position (P LS), wherein in the storage position (P ST) the flexible structure is adapted to be positioned on a first height from the cargo floor, wherein in the load securing position (P LS) the flexible structure is adapted to be positioned on a second height from the cargo floor, wherein the first height is different from the second height, wherein the positioning arrangement comprises two or more holding devices (5a,5b,5c,5d), wherein a positioning member (16a,16b,16c,16d) is movably connected to each holding device (5a,5b,5c,5d), wherein the flexible structure at different positions along an outer periphery comprises two or more connection members (6a,6b,6c,6d), wherein each connection member (6a,6b,6c,6d) is adapted to be connected to a corresponding positioning member (16a, 16b, 16c, 16d), wherein each positioning member (16a,16b,16c,16d) is connected to an actuator, wherein the actuator is adapted for moving each positioning member (16a,16b,16c,16d) in relation to the corresponding holding device (5a,5b,5c,5d) for positioning the flexible structure between the storage position (P ST) and the load securing position (P LS), wherein each positioning member (16a,16b,16c,16d) is connected to the actuator via a wire structure, wherein each wire structure is adapted for displacing the corresponding positioning member (16a,16b,16c,16d) in relation to the corresponding holding device (5a,5b,5c,5d) upon activation of the actuator, wherein when the actuator is pulling the wire structures, the positioning members (16a,16b,16c,16d) are moved in a direction downwards in relation to the holding devices (5a,5b,5c,5d) towards the floor structure, characterized in that each positioning member (16a,16b,16c,16d) is connected to the corresponding holding device (5a,5b,5c,5d) via a spring (10a,10b,10c,10d), wherein each spring (10a,10b,10c,10d) is adapted for displacing the corresponding positioning member (16a,16b,16c,16d) in relation to the corresponding holding device (5a,5b,5c,5d), wherein when the actuator is releasing the wire structures, the positioning members (16a,16b,16c,16d) are moved in a direction upwards in relation to the holding devices (5a,5b,5c,5d) towards a ceiling structure due to the forces exerted on the positioning members (16a,16b,16c,16d) by the springs (10a,10b,10c,10d).
