Abstract: A buckle apparatus for use in a seatbelt system is arranged such that when a tongue plate is inserted into a buckle body, the tongue plate retaining portion of a lock plate pivotally supported on one side of the tongue plate insertion passage extends through an opening formed in the tongue plate and projects out to the other side of the insertion passage so as to engage with a subsidiary lock plate. Accordingly, the lock plate which prevents the tongue plate from being undesirably pulled out is supported by the buckle body on both sides of the tongue plate and therefore can bear a large load. To release the tongue plate, the subsidiary lock plate is pivoted so as to disengage from the lock plate, which requires only a reduced force.

Abstract: Disclosed is a novel pivot structure for a seat belt buckle wherein a base plate of a seat belt buckle is connected to an anchor stay by way of a pin and spring means interposed therebetween in such a manner that the buckle may pivot relative to the anchor stay about the pin along the major surface of the anchor stay and, additionally, away from the major surface. The spring means biases the buckle toward a neutral position in which the buckle aligns with the axial line of the anchor stay. Thus, the seat belt buckle is maintained in a relatively rigid state relative to the anchor stay so that a tongue plate may be easily aimed and inserted thereinto. However, once the seat belt is securely fastened by the engagement of the tongue plate and the seat belt buckle, the buckle may pivot in any direction relative to the anchor stay and therefore will readily bend to conform to the body of the person wearing the seat belt and improve the comfort in wearing the seat belt.

Abstract: In a safety belt for a car or the like, a buckle is provided to receive a tongue releasably. The buckle includes a latch member engageable with the tongue, a U-shaped base defining an opening in the direction of insertion of the tongue and supporting the latch member turnably, and a bridge secured to the lower end of the base and having engagement portions which when the tongue is in a state kept in engagement with the latch member, are kept in engagement with the tongue at two points. Owing to this structure, the tongue can be firmly held without play and the buckle can withstand large forces and moments applied thereto by way of the tongue.

Abstract: A buckle apparatus for use in a seatbelt system is arranged such that when the tongue plate of the seatbelt is inserted into the buckle body, the pawl of a lock plate is inserted into an opening formed in the tongue plate. Since the projecting end of the pawl is separated from the corresponding opening formed in the buckle body, a relatively small force can release the tongue plate from the buckle apparatus. However, when the force applied to the tongue plate for pulling it out from the buckle apparatus increases, a lock plate holder is deformed by virtue of this force. In consequence, the pawl engages with the opening of the buckle body, and retaining wings provided on the side of the lock plate remote from the pawl also engage with the corresponding portions of the buckle body. Accordingly, the lock plate is supported by the buckle body at two portions on both sides of the portion thereof which engages with the tongue plate, so that the lock plate can bear a large tongue plate pulling out force.
