ABSTRACT:
A spring driven belt reeling mechanism for safety belts (17) in motor vehicles has a belt reel (11) which is rotationally fixedly connected to a first thread reel (12), having a helical guide groove (15). A flexible thread (13) is wound onto the guide groove (15) and extends to a second thread reel (14) with a helical guide groove (18). The two thread reels (12, 14) taper in opposite axial directions. The second thread reel (14) is acted on by a spiral spring (16) in the direction of rotation such that the safety belt (17) is wound onto the belt reel (11). The spiral spring (16) is arranged in its own spring housing (49) in such a way that it is rotationally fixedly mounted radially outwardly at the spring housing (49) and radially inwardly at a spring core bearing (30).
