Load carriage systems are described including one or more of a first chest panel, a first back panel, and a self-adjusting cummerbund connecting the first chest panel and the first back panel. The self-adjusting cummerbund may include a tensioning mechanism configured to allow the cummerbund to extend and retract, and may be configured to provide varying resistive force. The tensioning mechanism may include one or more of a sliding portion, a continuous patterned length of material that is folded over itself, and an elastic member that is attached to the sliding member and the length of material. Body armor plates may be held between outer and inner chest panels and/or between outer and inner back panels. A strip of webbing may be used to secure the body armor plate between the outer and inner panels.

Disclosed is a cylinder-retaining apparatus for a breathing apparatus comprising first and second fixing point and a strap apparatus secured to the first fixing point and the second fixing point. The strap apparatus forms a main strap loop for extending around and securing one or more cylinders. The cylinder-retaining apparatus is configurable in: i) an expanded configuration in which the main strap loop provides a first effective length for securing a first number of cylinders; and ii) a contracted configuration in which a portion of a strap of the strap apparatus is folded to form a secondary strap loop and the secondary strap loop is secured to a third fixing point such that the main strap loop forms a second effective length which is shorter than the first effective length and for securing a second number of cylinders less than the first number of cylinders.

An improved strap tie-down device that includes two primary components, namely a base frame and a lever arm, and further includes a cam and a locking mechanism.

A belt buckle has a main body, a rotatable shaft assembly, an elastic member and a controlling member. The main body has a front piece and two side pieces paired and connected with each other. A shaft rod and a stopping portion and an arced edge are formed on the side piece. The elastic member is provided inside the rotatable shaft assembly and is pivoted together on the shaft rod. The controlling member uses its controlling ends to be pivoted on the shaft rod. When the toothed portion is pushed to rotate the rotatable shaft assembly, the engaging bar of the rotatable shaft assembly can slide along the arced edge of the side piece. At this time, the controlling end of the controlling member is not linked by the engaging bar, the controlling member can be fixed in place when the belt is penetrated.
