The present application includes embodiments for a belt adjustment system. The belt adjustment system can be configured to engage a belt comprising a plurality of belt teeth. The belt engagement system can include a buckle portion that includes a belt clamp configured to couple the belt to the buckle, a lever pivotally movable between a first position and a second position, and a belt-engaging tab, the tooth-engaging tab positionable between a tooth-engaging position and a tooth-disengaging position responsive to the position of the lever on. The belt adjustment system can include a tool housing having a first wall and a second wall that form a slot. A tool comprising a distal end and a proximal end can be coupled to the tool housing, the tool positionable within the slot between a closed position and an open position.

A safety device for preventing accidental discharge of an airbag. A lower portion of the safety device includes two opposing sidewalls at least partially defining a cavity for holding a seat belt buckle assembly. An upper portion of the safety devices is hingedly coupled to the lower portion. The safety device also includes a mechanism for securely latching the upper portion to the lower portion and a mechanism for releasing the upper portion from the lower portion when the upper portion is securely latched to the lower portion to allow the upper portion to rotate away from the lower portion.

The present disclosure relates to a helmet buckle. The helmet buckle according to the present disclosure comprises: a base part (100) for guiding a band part (400) to slide when the band part (400) advances or retreats; a locking part (200) rotatably coupled to the base part (100), and fastened to the band part (400); and an operating part (300) which is rotatably coupled to the base part (100), and which rotates the locking part (200) so as to separate the locking part (200) from the band part (400) if the operating part rotates at least a predetermined angle with respect to the base part (100).

A safety belt buckle assembly is provided, wherein the safety belt buckle assembly includes: a main body; a connection member connected to the main body and configured to be releasably connected to a buckle member, and including a hooked portion, a body portion and an operation portion, the body portion being swingably connected to the main body, the hooked portion being configured to be hooked on the buckle member; a reel column positioned to the main body and configured for a belt to wind around; and a locking member movably connected to the main body and movable between a locking position and a release position; wherein when the locking member is in the locking position, the locking member and the reel column clamp the belt, and when the locking member is in the release position, the locking member and the reel column unclamp the belt.
