Abstract: A buckle structure contains a male buckle, two fastening arms, and a resilient sheet. The male buckle includes a first opening, a second opening opposite to the first opening, an external fence, and an accommodation cavity, wherein the external fence has two first orifices. Each of the two fastening arms includes a through hole, an engagement portion, a first abutting face, a second abutting face, and a column rotatably connected with the first orifice and the through hole so that the first abutting face and the second abutting face are located in the accommodation cavity of the male buckle, and the engagement portion of each fastening arm extends out of the first opening of the male buckle. The resilient sheet is formed in a U shape and includes a convex arc face and two contacting segments arranged on two ends of the resilient sheet respectively.

Abstract: Adjustable fire fighters' suspenders that are physiologically conformable when used with bunker pants. The suspenders are designed for comfort, proper fit, and flexibility in movement that corresponds with the movement of the wearer during normal fire fighting activities. The suspenders include a back sliding loop and elastic straps which have a predetermined limit of stretch at the four ends of the shoulder straps which connect the suspenders to the bunker pants. The suspenders provide an improved distribution of weight and increased support of heavy bunker pants and reduce the problem of "bunker bounce".
