<p>The inertia safety belt winder comprises a spring-loaded winder shaft on which is rotatably mounted an inertia locking plate (7). During jerky acceleration of the winder shaft, the locking plate moves in the axial direction of the winder shaft into a locking position from a release position in which its locking elements are disengaged from counter-locking elements on the housing, by axial oblique cam and counter-cam surfaces (14a, 15a) on the locking plate and winder shaft. In the winder shaft is at least one angled recess (15), and on the locking plate is at least one hooked projection (14) which when assembled is inserted in the recess against the action of a release spring, to form a bayonet-type connection. In the rotational phase of bayonet closure movement, the cam surface which is on the hooked projection abuts against the counter-cam surface in the recess.</p> |
