摘要： A seat belt buckle adapted to releasably engage a latch plate 42 having an aperture 40 therein, the buckle comprising a rigid frame 10 including a base 12 having an opening therein, upstanding side walls 14 adapted to guide the latch plate longitudinally of the frame, a bar 16 extending transversely of the frame between the side walls, the bar being spaced above the base, a locking member 24 pivotally mounted on the frame and pivotal between a lower latched position and an upper unlatched position, the locking member carrying a downwardly projecting locking element 38 engageable in the aperture 40 in the latch plate 42 to retain the latch plate in place and passing into the opening, a slider 44 slidable longitudinally of the locking member between a first position in which it is located under the bar 16, to retain the locking member in the lower latched position and a second position in which it is resiliently engaged against the rear of the bar to retain the locking member in its upper unlatched position, a push button 52 to push the slider from its first position to its second position, a slider spring 48 to urge the slider towards its first position, a pair of wings 30 extending laterally from the locking member and engaging in the side walls to pivotally and resiliently mount the locking member for movement between its upper and lower positions and a pair of arms 34 extending laterally along the member, the pair of arms engaging abutments on the rigid frame to prevent flexing of the wings beyond their elastic limit.

摘要： A retainer mechanism for a safety belt includes a retraction reel on which the safety belt web is wound and first and second locking members mounted adjacent the reel and movable relative to the frame to clamp the web itself or allow the web to move. Displacement of the second locking member, and thus of the first locking member, may be caused e.g. by an inertia mechanism on the reel and/or by an acceleration/de-celeration sensitive mechanism and/or by a projection adjacent the end of the web.

摘要： The safety belt pre-tension assembly comprises a support 14, a safety belt buckle 10 mounted on the support for axial displacement relative to the support, a housing 40, a winding reel 44 mounted within the housing and a helical power spring 52 associated with the reel to cause rotation of the winding reel. A flexible cable 34 has one end connected to the winding reel, so that the flexible cable will be wound thereon upon operation of the power spring. The other end of the flexible cable 34 is connected to the buckle 10 to move the buckle axially in a first direction effective to tension a safety belt held by the buckle. Actuation means 54-70 are provided to trigger actuation of the spring 52 upon the actuation means being subjected to a deceleration greater than the predetermined value. Locking means 26-32 are provided to allow the buckle to move in the first direction only, but not in the opposite direction.
