Optics () for an illumination device (), as well as an illumination device () comprising such optics. The optics comprise at least one lens () with a light entry surface () and a light exit surface (). A stepped lens structure (), such as a Fresnel structure, is formed on the light exit surface. A recurring surface structure, such as periodically arranged prominences () and deepenings (), are formed on the light entry surface ().

Optics for an illumination device and illumination device

A switch for a belt buckle of a seatbelt device including at least two contact elements () abutting on each other or reaching into abutment on each other in a cavity of the switch, wherein at least one of the contact elements () is configured as a movable contact spring. An insertion channel () is provided into which a belt tongue, a locking part, an ejector () or a part movably coupled with one of these parts is insertable and removable at least with a section during the locking and unlocking movement of the belt tongue. A movably supported coupling member () protrudes with a first section () into the insertion channel () and includes a second section () associated with the contact spring. The movably supported coupling member () abuts via the second section () on the contact spring in a position-independent manner.

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.
