A rescue strap assembly comprising a connector, an adjuster, a mechanical advantage assembly, and a strap having a first end, an intermediate portion, and a second end. The first end is operatively connected to the connector and the mechanical advantage assembly, the intermediate portion is routed through the adjuster, and the mechanical advantage assembly is configured and arranged to engage at least a portion of the intermediate portion.

The present application includes embodiments for a belt adjustment system. The belt adjustment system can be configured to engage a belt comprising a plurality of belt teeth. The belt engagement system can include a buckle portion that includes a belt clamp configured to couple the belt to the buckle, a lever pivotally movable between a first position and a second position, and a belt-engaging tab, the tooth-engaging tab positionable between a tooth-engaging position and a tooth-disengaging position responsive to the position of the lever on. The belt adjustment system can include a tool housing having a first wall and a second wall that form a slot. A tool comprising a distal end and a proximal end can be coupled to the tool housing, the tool positionable within the slot between a closed position and an open position.

Described herein is a retractable safety assistive belt assembly for use in transferring disabled or senior patients. The belt assembly includes a retractor assembly, a buckle mechanism, a latch member, a quick-release button, a strap or band member, and an optional belt clip attached to an external part of a housing. The strap or band member optionally includes measurement markers. In a related embodiment, an optional belt assembly case is provided for storage and portability of the belt assembly.

In a buckle device, a buckle body is held in an upper part of a boot, and a lower part of the boot is supported from the lower side by a frame and a protector. Here, an upper left inclination surface of the boot and the lower left inclination surface of the protector are inclined in a downward direction as being directed inward in the right-left direction of the boot. Therefore, in a case in which a load is input to the boot from the upper side, it is possible to apply a displacement force to the boot inward in the right-left direction of the protector, and to suppress the downward displacement of the boot with respect to the frame and the protector.
