ABSTRACT:
A safety belt retractor is provided with a dual-tension comfort function. Between the belt reel and housing a retractor spring and an auxiliary spring of weaker spring force than said retractor spring are connected functionally in series via a ratchet wheel. The rotation of said ratchet wheel is selectively blockable by a pawl. The transition between diminished and undiminished tension in the webbing takes place gently, jerk-free and silently because the rotation of the ratchet wheel is inhibited by a brake means as long as the auxiliary spring is not completely or at least almost completely tensioned. Said brake means includes lever-like engagement elements which are pivotally mounted on the ratchet wheel and which are moved by the pressure exerted by the outer periphery of the auxiliary spring in the axial direction to activate a friction brake.
