A winding device includes a case that includes a cable lead-out path, a rotating body that is accommodated in the case and is supported to be rotatable, and a cable that has one end connected to the rotating body to be wound in the case and the other end passing through the cable lead-out path of the case to be pulled out to an outside of the case. In the winding device, a first foreign substance removing portion and a second foreign substance removing portion which remove foreign substances pulled in together with the cable, are provided in the cable lead-out path, and the second foreign substance removing portion is capable of removing the foreign substances smaller than the foreign substances that are removable by the first foreign substance removing portion.

A belt reel (14) for a belt retractor (10) has a rotational axis (R) and a reel body (16) that is provided as a reel for a webbing (24) and has a first axial circumferential circle (34). The reel body (16) further includes a radial constriction (32) having a second axial circumferential circle (36), wherein the constriction (32) is arranged centrally on the reel body (16) in the axial direction (A) and wherein the circumference of the second axial circumferential circle (36) amounts to a maximum of 95% of the circumference of the first axial circumferential circle (34). Moreover, a belt retractor (10) comprising such belt reel (14) is described.

A seat belt retractor which is mounted in a mounting space formed on a backrest of a seat installed in a vehicle and comprises a spindle module including webbing and a spindle having the webbing wound on the outer surface thereof, wherein the spindle is arranged along the longitudinal direction of the vehicle corresponding to the thickness direction of the backrest in the mounting space, such that by rotating the direction in which the spindle, on which the webbing is wound, is installed, the width in the longitudinal direction mounted on the backrest of the seat can be minimized, thereby making the retractor more slender.

The disclosure relates to adjusting a vehicle seat configuration inside a vehicle. The vehicle seat configuration can comprise a vehicle seat and an actuator system for adjusting the vehicle seat configuration. The actuator system can comprise at least one actuator, and the at least one actuator can comprise a brushless electric motor. A corresponding method can comprise receiving, by a controller comprising a processor, at least one signal indicative of a collision situation of the vehicle, and providing, by the controller, upon receival of the at least one signal, control instructions for the actuator system to adjust the vehicle seat configuration.

The present application discloses a child safety seat and a safety belt adjustment system thereof. The safety belt adjustment system includes: an automatic retracting device including a retracting shaft and a retractor, the retracting shaft being configured to be connected to a safety belt, the retractor driving the retracting shaft to perform a retracting rotation, so as to tension the safety belt in a buckled state; and a first locking device including a drive button and a locking member; the drive button being configured to drive the retracting shaft to perform a release rotation. The locking member has a locked position. In the locked position, the locking member locks the retracting rotation of the retracting shaft.

A belt tightener for a safety belt system in a motor vehicle comprises at least one electric actuator. A decentralized, independent electric energy store designed to store a sufficient amount of electric energy for operating the actuator is dedicated to the belt tightener.
