Abstract
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.
