Abstract: A switch adapter is integrateable into a seat belt lock and used for monitoring the locking and unlocking state of the lock. The switch adapter includes a monolithic plastic part and is at least two adapter areas which are movable with respect to each other. The first adapter area carries a first switch element and the second adapter area carries a second switch element. The switch adapter is suitably integrateable into the lock of the seat belt which is provided with a frame and a locking element which is movably mounted so as to switch the seat belt buckle between a locking position and an unlocking position. The switch adapter is used for detecting the locking state of the seat belt locking element. For this purpose, the switch adapter and the locking element are actively connectable to each in such a way that the switching state of the switching adapter and the position of the locking element are modifiable only simultaneously.

Abstract: Hall sensor arrangement is disclosed for detection of the change in the position of two components which can move relative to one another into two end positions, with a Hall sensor with at least one Hall measurement field (H; H1, H2) and a field magnet. An actuator is provided for transmitting to the Hall sensor the change in the position of the two components which can move relative to one another. The Hall sensor and the field magnet are combined into a preassembled structural unit. When the position of the field magnet changes relative to the Hall sensor from one end position into the other end position the polarity of the magnetic field acting on the Hall measurement field (H; H1, H2) can change, e.g., the polarity becomes reversed.

Abstract: The disclosure relates to a switch adapter integrateable into a seat belt lock and used for monitoring the locking and unlocking state of the lock. Said switch adapter is embodied in the form of a monolithic plastic part and is provided with at least two adapter areas which are movable with respect to each other. The first adapter area carries a first switch element and the second adapter area carries a second switch element. Said switch adapter is in suitably integrateable into the lock of the seat belt which is provided with a frame and a locking element which is movably mounted with respect thereto, makes it possible to lock the seat belt buckle in the locking element thereof in a locking position and is unlocked in the unlocking position. The switch adapter is used for detecting the locking state of the seat belt locking element.
