  • Patent number: 4555832
    Abstract: Disclosed herein is a buckle assembly suitable for use in a vehicle seat belt. The buckle assembly includes a clinched anchor block fixed on a wire and having an interlocking portion projecting downwardly therefrom, a buckle base having a bottom wall defining a matching interlocking portion, which is in engagement with the interlocking portion of the anchor block, and a pair of side walls extending downwardly from the bottom wall. The anchor block is connected directly to both of the side walls of the buckle base. The interlocking portion of the anchor block is press-fit in the matching interlocking portion in the bottom wall of the buckle base. The clinch force of the anchor block against the wire is thus not reduced by the fixing work of the anchor block to the buckle base.
