A spring-driven reeling mechanism for safety belts 17 in motor vehicles has a belt reel 11 which is rotationally fixedly connected to a first draw reel 12 with a spiral-shaped guide groove 15. A flexible draw member 13 is wound into the guide groove 15 and extends to a second draw reel 14 with a spiral-shaped guide groove 18. The two draw reels 12, 14 taper in opposite axial directions. The draw reel 14 is acted on by a spiral spring 16 in a direction of rotation such that the safety belt 17 is wound onto the belt reel 11. The spiral spring 16 is accommodated in a hollow cavity 21 of the second draw reel 14.

Spring-driven reeling mechanism for safety belts (17) in motor vehicles comprising a belt reel (11) which can be blocked against rotation in the pull-out direction by a pull-out lock (40) triggerable by accelerations caused by an accident and/or with an attempted rapid pull-out of the safety belt (1

Spring-driven reeling mechanism for safety belts (17) in motor vehicles comprising a belt reel (11) which can be blocked against rotation in the pull-out direction by a pull-out lock (40) triggerable by accelerations caused by an accident and/or with an attempted rapid pull-out of the safety belt (17) and which is rotationally fixedly connected to a first draw reel (12) which tapers in an axial direction and has a spirally-shaped groove (15) on its periphery; wherein the first draw reel (12) is rotationally fixedly connected, via a flexible draw member (13) wound contrary to the direction of winding of the safety belt (17) on the belt reel (11) into the guide groove (15) and secured at one end to the first draw reel (12), to a second draw reel (14) which tapers in the opposite axial direction and is arranged parallel to and aligned sideways relative to the first draw reel (12), with the second draw reel (14) having a spiral guide groove (18) and with the other end of the draw member (13) being secured to the second draw reel (14) and being wound into the guide groove (18), wherein said second draw reel (14) is biased by a spring arrangement (16) in a direction such as to wind the draw member (13) onto the second draw reel (14) and the safety belt (17) onto the belt reel (11), and wherein the two guide grooves (15, 18) are so shaped and arranged on the draw reels (12, 14) that the tensioned draw member (13) which connects the two draw reels (12, 14) passes essentially kink-free into the two draw member windings on the draw reels (12, 14), characterized in that the spring arrangement (16) is accommodated in a hollow cavity (21) of the second draw reel (14) which is surrounded at least partly by the guide groove (15), and the hollow cavity (21) is covered by a cover (52) secured axially to the second draw reel (14) in such a way that the spring arrangement (16) is only surrounded by parts which rotate with the second draw member (14).
