The invention describes a mainspring (10) for a belt retractor (24). Furthermore, a belt retractor (24) for a seat belt device of a vehicle is provided which comprises a belt reel (26) which is supported rotatably about a central axis (26a) in a belt retractor housing (28), and a mainspring (10) for rotationally restoring the belt reel (26). Accordingly, the mainspring (10) includes plural windings (30) extending in a substantially helically nested manner in its state mounted in the belt retractor (24). The mainspring (10) is disposed substantially concentrically to the central axis (26a).

The invention discloses a belt retractor comprising a frame (10), a belt reel (12) which is arranged rotatably in the frame (10) and can receive a seat belt (14), at least one load limiter (16) which enables the belt reel (12), when it overcomes a braking torque provided by the load limiter (16), to rotate relative to the frame (10) so as to release seat belt (14), and a switchable clutch (26) including a switching cage (22) and coupling elements (24), wherein the switching cage (22) can be shifted by means of an actor (28) from an open position in which the coupling elements (24) are maintained disengaged from the belt reel (12) to a closed position in which the coupling elements (24) engage the belt reel (12). In order to achieve a compact design, the belt retractor includes an actuator (38) which is coupled to the actor (28) and a freewheel (40) which couples the switching cage (22) to the actuator (38) so that the actuator (38) can shift the switching cage (22) from the open position to the closed position.

A webbing retractor includes a spool, a motor, a force limiter mechanism, a first rotating body, a second rotating body, a ratchet gear, a pawl body and a control section. The ratchet gear is provided at one of the first rotating body or the second rotating body. The pawl body is provided at another of the first rotating body or the second rotating body. The pawl body can engage with the ratchet gear in a case in which the first rotating body rotates toward one side, and engagement of the pawl body with the ratchet gear being cancelled in a case in which the first rotating body rotates toward another side. The control section drives the motor to rotate in reverse, such that the first rotating body rotates toward another side in a case in which a physical amount relating to load of the passenger exceeds a predetermined value during forward rotational driving.

A winding device includes a base, a driving member and two operation gears. The winding device further includes two shafts extending through each of the arms, each of the operation gears, and each of the ears. The base is provided with two arms. The driving member is provided with two ears. Each of the operation gears has a plurality of toothed portions and a plurality of push grooves. Each of the toothed portions has a release face. Each of the arms is provided with a first slideway in which a first push member is slidably mounted. Each of the ears is provided with a second slideway in which a second push member is slidably mounted. Thus, the driving member is driven reciprocally to wind the safety belt gradually, such that the tension of the safety belt is adjusted.
