A safety-belt arrangement comprises a safety-belt (10), one end of which is connected to a retractor (11) and the other end of which is connected to a spool (13) to be wound on the spool. The spool is slidably mounted on a bar (15) which is located adjacent the side wall of the vehicle, and which is extends rearwardlay of the front seat of the vehicle towards a rear seat. The spool (13) is rotatable about an axis which is coincident with the axis of the bar for altering the amount of safety-belt wound on the spool. A pre-tensioner (18) with a load-limiting effect is provided to apply, by means of a wire (19) a rotational force to a wheel (21) which is splined to the shaft, the reel (13) also being splined to the shaft.
