LASANORDNING VID SEKERHETSSELAR FOR FORDON

摘要

A locking device for seat belts intended for vehicles of the type in which a strap being a part of the seat belt is automatically drawn into and wound up on a rotatable coiling shaft when the seat belt is not used, to temporarily lock the shaft. The device comprises a ratchet means non-rotatably arranged on the shaft; a locking means fixedly mounted in relation to the shaft; at least one locking body accommodated in the locking means and arranged for displacement from a neutral position to a locking position in which the locking body engages with the ratchet means for preventing rotation of the shaft; and a rotatably mounted guiding means. The guiding means is provided with a guiding surface for the locking body and is coupled to the shaft at the beginning of the locking operation to be turned by the shaft on its rotation due to withdrawal of strap from a normal position to a locking position and thereby to move the locking body to the locking position.
