A belt retractor () includes a frame () provided with locking teeth (). A belt reel () is rotatably supported in the frame () and provided on at least one axial end with ratchet teeth () adapted to engage in the locking teeth (), when the belt reel () is shifted from a home position into a locked position. A locking bearing () interacts with the belt reel () on the side where the ratchet teeth () are arranged and keeps the belt reel in the home position up to a first load threshold. A load bearing () interacts with the belt reel on the opposite side and keeps the latter in the home position up to a second load threshold. The first load threshold is lower than the second load threshold.

Belt retractor, and method for locking a belt retractor

A seat belt retractor () comprises a frame (), a belt reel () which is rotatably mounted in the frame (), and a blocking pawl () which is provided at the belt reel () and is capable of engaging with a blocking teeth system (). The blocking teeth system () is provided at a blocking ring () which is mounted at the frame () in a rotationally limited manner.

Seat belt retractor

An inertia sensor for vehicle-sensitive activation of a belt retractor blocking mechanism, has a mass body, a support for the mass body, and a sensor lever having a control pawl and being mounted on the support for swivelling motion about a swivel axis and resting on the mass body. The support is provided with a first circular cylindrical surface area with a axis which is parallel to the swivel axis and runs through the center of gravity of the mass body. An appendix is formed on the first circular cylindrical surface area of the support for mounting the support to the belt retractor. Further, a belt retractor with the inertia sensor and injection molds for molding the support and the sensor lever are provided.
