Abstract
A seat belt lock with a Hall sensor for detection of a locking state of a seat belt lock having a metal seat belt lock frame arranged in a housing. The seat belt lock frame has an upper part and a lower part, connected to a define slit-like channel. A spring-loaded locking device for an inserted seat belt latch is mounted on the seat belt lock frame. A spring-loaded ejector for the inserted seat belt latch is arranged in the channel. The Hall sensor interacts with a permanent-magnetic component, whose distance relative to the Hall sensor is changeable based on translatory movement of the ejector in the case of actuation of the locking mechanism. The Hall sensor is arranged on or in the seat belt lock frame and is covered by a metal shielding element, which extends essentially parallel to the seat belt lock frame and forms a flow concentrator.
