ABSTRACT:
A safety belt reeling device with comfort function has a housing and a reeling shaft rotatably supported in the housing. A pawl wheel is fastened to the reeling shaft and switchable between a locked position in which rotation of the pawl wheel is blocked and a release position in which the pawl wheel is rotatable. A winding spring, connected with a first end to the housing and with a second end to the pawl wheel, is provided for rotating the reeling shaft when the pawl wheel is in the release position. A comfort spring with a weaker spring force than the winding spring is provided. The comfort spring is connected with a first end to the pawl wheel and with a second end to the reeling shaft. The pawl wheel has a stay with a first and a second end. The first end of the comfort spring is guided in a single loop about the first end of the stay. An elastically deformable dampening element is positioned between the first end of the stay and the single loop. The dampening element reduces the load impact on the comfort spring, when the pawl wheel is switched into the release position, by allowing a displacement of the single loop relative to the stay.
