The buckle assembly can further include a magnet operably coupled to the latch, and an electronic switch operably positioned in the housing. The latch is configured to move between a first latch position in which the latch is disengaged from the tongues, and a second latch position in which the latch is engaged with the tongues. Movement of the latch from the first latch position to the second latch position moves the magnet relative to the electronic switch. In some embodiments, the electronic switch can include a Hall effect sensor that outputs a signal in response to movement of the magnetic field that is indicative of the engagement status of the latch.

A webbing adjustment device has a cover, a frame, a slider, and a guiding ring member. The frame is up and down moveably disposed in the cover. The slider is located in the cover, is moveably disposed in a body of the frame, and has a through slot formed through the slider. Webbing inserted through the through slot is locked or unlocked by a relative motion between the frame and the slider. The guiding ring member is detachably disposed on the cover, and has a guiding ring and a positioning element connected to the guiding ring. The webbing is inserted through the guiding ring.
