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.

A buckle assembly which comprises a clinched anchor block fixedly connected to a wire and provided with a first interlocking portion at an upper part and a second interlocking portion at a lower part, a buckle base having at least one bottom wall provided with an interlocking portion which is staked with the second interlocking portion, and a support member held on the buckle base and engageable with the first interlocking portion. Owing to the adoption of the above structure, the buckle assembly according to this invention is generally flat and can withstand relatively great loads.
