A compact ratcheting buckle mechanism which enables significant mechanical advantage can be used in a multitude of devices. The compact ratcheting buckle mechanism comprises a base plate which holds a ratchet tab and release tab, which are spring-loaded and held in place by pivot pins which pass through slots in the base plate. The ratchet and release tabs are then able to articulate. The ratchet tab teeth engage with a compatible ratchet ladder strap, which passes through the compact ratcheting buckle mechanism linearly when the ratchet tab is articulated. The release tab holds applied tension in the compact ratcheting buckle mechanism, and is substantially covered by the ratchet tab to ensure for a compact design and low chance of accidental release. The compact ratcheting buckle mechanism can be released through a defined pincer motion, disengaging both the ratchet tab and release tab teeth from the compatible ratchet ladder strap.

A buckle having an adjustable loop end forming a primary plane with opposing side walls. The adjustable loop end has a central bar positioned between a first strap opening and a second strap opening. A pair of slots operable to receive the terminal ends of the central bar are recessed into the interior surface of the opposing side walls with the bottom edges of the slots being longer than the top edges. A pair of tabs on opposite ends of the central bar extend outward from the central bar along a longitudinal axis of the primary plane and towards the second strap or belt opening. Optionally, a protrusion extends from a lower surface of the fixed loop end wherein the protrusion is positioned at a right angle with respect to a vertical axis of the primary plane.

An end cover to be attached to an end of a string is provided. The end cover includes a finger-hooking projecting portion having a first finger-hooking face, and a base portion having a second finger-hooking face, and the second finger-hooking face is provided at a position to suppress a rotation of the end cover as a support point of the first finger-hooking face when a pulling force acts on the string using the first finger-hooking face.

A buckle with a string adjustment portion includes a plug and a socket. The plug includes: a tightening string member attachment portion configured to slidably lock a string member and adjust a length of the string member; and leg portions which are inserted into and engaged with the socket. The socket includes a fitting portion including an insertion opening. An insertion hole through which the string member is inserted is formed to penetrate the tightening string member attachment portion, and a portion connecting the leg portions side of the insertion hole serves as a second bar. The second bar is located on an insertion direction side of the leg portions with respect to a position where an end portion of the plug and the insertion opening of the socket are abutted against each other, in a state where the leg portions are engaged with the socket.

A belt adjuster configured to secure a belt of a child car seat. The belt is squeezed and/or compressed between a belt bar and a frame to prevent movement of the belt. The belt adjuster includes a trigger configured to function as a lever. In one example, the lever extends from a belt bar to the trigger, such that force applied to the trigger actuates the belt bar. The lever is configured to multiply a force applied to the trigger to reduce the force needed to release the belt. In one embodiment, a force vector applied to the trigger is in a parallel and opposite direction from a force vector of the belt bar. In another embodiment, a force vector applied to the trigger is in a parallel and/or transverse direction from a force vector of the belt bar.

A tilt-lock adjuster system includes a tilt-lock adjuster that is used to tighten and loosen webbing. The tilt-lock adjuster includes an indicator configured to indicate when proper tension is applied to the webbing. The tilt-lock adjuster has a frame to which the indicator is slidably coupled and a web bar slidably coupled to the frame. The web bar is asymmetric for one way assembly with the frame. The web bar has a web engagement notch that is concave for enhancing locking of the webbing to the frame. The web bar has a frame guide slidably engaged to the frame. The frame defines a web opening in which the frame engagement ledge extends. The frame guide of the web bar includes a key guide foot. The frame has an orientation notch configured to receive the key guide foot of the web bar.
