ABSTRACT:
A seat belt buckle includes a housing having a pivotally mounted detent movable between a latched position in which a latch tab on the detent is inserted into an aperture in a latch plate and an unlatched position permitting latch plate entry and exit from the buckle. The detent is biased to the unlatched position by a detent spring. A keeper is slidably movable on the housing between an extended position overlying the detent to block detent movement to the unlatched position by inertia forces and a retracted position permitting detent movement to the unlatched position. An end depress pushbutton is slidably mounted on the housing for extension by a spring and retraction by the seat occupant depressing the pushbutton. Pushbutton retraction retracts the keeper from blocking the detent so the detent spring moves the detent to the unlatched position. Mating abutments on the keeper and detent maintain the keeper in the retracted position while the detent spring holds the detent in the unlatched position so that a subsequent entry of the latch plate into the buckle may be accomplished without the added effort necessary to move the detent out of the way. The pushbutton spring returns the pushbutton to the extended position subsequent to each retraction. A flexure element attached to the detent extends into the path of latch plate entry and pivots the detent to the latched position simultaneous with arrival of the latch plate at the fully inserted position within the buckle.
