摘要： A seat belt buckle 10, having a pivoted locking member 26 adapted to releasably engage with a cross-bar 34 of an apertured latch plate 24 insertable within a latch passage 22 in the seat belt buckle, includes a rigid frame 12 having an apertured rectangular base plate 14, upstanding side walls 16 extending from longitudinal edges of the base plate 14, and a fixed bar 18 extending across the width of the base plate 14, parallel to, and spaced apart from, the base plate, the fixed bar 18 being secured at each end thereof to a respective side wall 16. The locking member 26 is pivotally supported by the frame side walls 16 so as to pivot about an axis substantially parallel to, and spaced apart from, the fixed bar 18 of the frame 12, between a latched position, in which the locking member 26 retains the latch plate 24 within the latch passage 22 in the buckle, and an unlatched position, in which the locking member 26 is held clear of the latch passage 22, the locking member 26 including a depending lock bar 32 extending therefrom, which lock bar 32 extends across the latch passage 22 and into an aperture 60 of the apertured base plate 14 of the frame 12 when the locking member 26 is in the latched position, there being a predetermined clearance existing between a forward edge 86 of the lock bar 32 and a forward edge 80 of the aperture 60 when the locking member 26 is in the latched position. The locking member 26 is pivoted in the frame side walls 16 by elastically-deformable integral wing portions 28, which wing portions will elastically deform when the buckle in a latched condition is subjected to applied loads beyond a predetermined limit, so as to allow the forward edge 86 of the lock bar 32 to make contact with the forward edge 80 of the aperture 60 in the apertured base plate 14. A shaped blocking member 46 is slidably mounted upon the locking member 26 for longitudinal movement relative to the locking member between a first position, where the locking member is in the latched position and the blocking member 46 is interposed between the fixed bar 18 and the locking member 26 to block any pivotal movement of the locking member towards the unlatched position, and a second position, where the locking member 26 is in the unlatched position and the blocking member 46 engages the fixed bar 18 to retain the locking member 26 in the unlatched position.

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 seat belt buckle 10, adapted to releasably engage with a latch plate 24 insertable within a latch passage 22 in the seat belt buckle 10, comprises: a rigid frame 12 having an open forward end 11 defining the latch passage 22, an opposite rearward end 13 adapted to be attached to a seat belt, an apertured rectangular base plate 14, an upstanding side wall 16 extending from each longitudinal edge of the base plate 14, and a fixed bar 18 extending across the width of the base plate 14 between the forward and rearward ends thereof, parallel to, and spaced apart from, the base plate 14, the fixed bar 18 being secured at each end thereof to a respective side wall 16. A locking member 26 is pivotally supported by said frame side walls 16 so as to pivot about an axis substantially parallel to, and spaced apart from, the fixed bar 18 of the frame, between a latched position as shown, in which the locking member 26 retains the latch plate 24 within the latch passage 22 in the buckle 10, and an unlatched position, in which the locking member 26 is held clear of the latch passage 22. A shaped blocking member 46 is slidably mounted upon the locking member 26 for longitudinal movement relative to the locking member 26 between a first position, where the locking member 26 is in the latched position and the blocking member 46 is interposed between the fixed bar 18 and the locking member 26 to block any pivotal movement of the locking member 26 towards the unlatched position, and a second position, where the locking member 26 is in the unlatched position and the blocking member 46 engages the fixed bar 18 to retain the locking member 26 in the unlatched position. A push button 20 is slidably mounted on the frame side walls 16 above the latch passage 22, for longitudinal movement relative to the frame base plate 14 so as to move the blocking member 46 from the first position to the second position. A coil spring 54 located between the blocking member 46 and the locking member 26 biases the blocking member 46 towards the first position. The fixed bar 18 is provided with a substantially knife-edged portion 27 which faces the rearward end 13 of the buckle 10 and extends across the width of the base plate; and the shaped blocking member 46 is provided with a sloping face 50 which makes essentially a line contact with the substantially knife-edged portion 27 of the fixed bar 18 throughout the pivotal movement of the locking member 26 from the unlatched position to a position in which the coil spring 54 can snap the blocking member 46 into the first position.
