A safety device, in particular one such as an under-run guard for improving the road safety of a large or heavy vehicle for vulnerable individuals such as pedestrians and cyclists, comprises an inflatable panel 100 mountable on a side portion of the vehicle 10. A biasing means (110, figure 7) is provided to bias the panel into a retracted configuration adjacent the side of the vehicle. The panel and the biasing means are configured such that, upon deployment, inflation of the panel overcomes the force exerted by the biasing means such that the panel is deployed toward the ground surface so as at least partially to obstruct the exposed area between the vehicle and the ground. The biasing means may comprise springs (172) or elastic cords or straps to apply a retracting tension to the inflatable panel. Linear elements such as roller chains (180) may guide the inflatable panel in a balanced manner. A brush (160) may be provided at a lower edge of the panel to close any gap between the panel and the ground. |
