<p>An electronic safety ski binding is provided with a holding magnet system as the tripping device of an unlocking device. The holding magnet system comprises a permanent magnet and an electromagnet. The unlocking device is set in operation by the holding magnet system when the excitation current (energising current) is switched on. In order to make an electronic safety ski binding usable in practice, the holding magnet system is constructed such that it has a relatively high efficiency, which results in a relatively low electricity consumption. The holding-magnet system is a quadrilateral frame structure whose base strip forms a permanent magnet (2), whose side strips are soft-iron cores (3, 4) and whose head strip forms a clapper-type armature (hinged armature) (5). The clapper-type armature (5) extends on one side beyond the soft-iron core (4) and forms a two-armed lever which can pivot about the frame corner point (13) and on whose second arm (9) a spring engages, which loads the clapper-type armature in the opening direction. Coils (6, 7) are arranged on the soft-iron cores opposite the clapper-type armature (5). <IMAGE></p> |
