Embodiment Construction

[0036] figure 1 A seat belt retractor 10 of a vehicle seat belt system, not shown in detail, according to a first embodiment is shown. The seat belt retractor 10 has a frame 12 in which a seat belt reel 14 is rotatably mounted, on which a seat belt (not shown) is wound, the seat belt being wound on the seat belt reel 14 And it can be pulled out from the belt reel along the belt pulling direction R.

[0037] On the locking side 16 of the seat belt retractor 10 ( figure 1 center right), the belt reel 14 has a locking pawl, not shown, which in the deflected position engages in a first locking engagement 18 which is formed directly on the frame 12 and The belt reel 14 is thus locked.

[0038] In the axial direction A of the seat belt reel 14 facing outwards next to the seat belt reel 14 is arranged a coupling disc 20 which is connected to the seat belt reel 14 in such a way that it can be rotated relative to the seat belt reel 14 by a predetermined amount. degree. A return sp...

Abstract

The invention relates to a seatbelt retractor (10) of a vehicle seatbelt system, having a frame (12) and a belt coil (14) which is mounted in the frame (12) and which is connected to a coupling disc (20) that can be rotated by a specified degree relative to the belt coil (14). The coupling disc (20) is equipped with a blocking pawl (24) which is arranged so as to be radially deflectable out of a base position and which engages into a blocking toothing fixed to the frame in a deflected position in order to block the coupling disc (20). The blocking pawl (24) is connected to the coupling disc (20) via two spring portions (42, 44) which are formed on at least one spring element, and each of the two spring portions (42, 44) has a pawl-side end, which is fixed to the blocking pawl (24), and a coupling disc-side end, which is fixed to the coupling disc (20).

Description

technical field [0001] The invention relates to a safety belt retractor of a vehicle safety belt system. Background technique [0002] During normal operation of the belt retractor, the belt can be pulled out of its belt reel against only slight resistance. Conversely, in the locked state of the belt retractor, belt extension is blocked in order to prevent further belt withdrawal. The latching state can be initiated in two ways: on the one hand, vehicle-sensitive engagement, ie if the acceleration force acting on the vehicle exceeds a certain threshold value, or belt-sensitive engagement, ie if the belt is pulled out The acceleration acting in the direction of the safety belt exceeds a predetermined threshold value. [0003] In the case of known seat belt retractors, the described vehicle-sensitive or seat belt-sensitive locking of the seat belt reel is carried out via a coupling disc which rotates together with the seat belt reel during normal operation. , but is rotatab...
