A seat belt buckle which is adapted to releasably engage a latch plate 42 having an aperture 40 therein. The buckle comprises a rigid frame 10 including a base 12 and upstanding side walls 14 adapted to guide the latch plate 42 longitudinally of the frame 10. A locking member 24 is mounted on the frame and carries a downwardly projecting locking element 38. The locking member 24 is pivotable between a lower latched position in which the locking element 38 engages the aperture 40 in the latch plate 42 to retain the latch plate in place, and an upper unlatched position. A pair of wings 30 extend laterally from the locking member 24 and engage in the side walls 14 to pivotally and resiliently mount the locking member 24 for movement between its upper and lower positions. The wings 30 are capable of elastic flexing upon axial loading of the locking member 24 by the latch plate 40. At least one stop member 34 extends laterally from the locking member 24 and engages abutments on the rigid frame 10, at least when the locking member 24 is in its lower position, to prevent flexing of the wings 30 beyond their elastic limit and the at least one stop member 34 is joined to an adjacent one of the wings 30 outside the side walls 14 of the frame 10. |
