Buckle assemblies having load indicating features and associated systems and methods are disclosed herein. In one embodiment, a buckle assembly includes a tang having an opening that receives a web to secure the buckle assembly to a vehicle or a seat structure. The tang also includes an elongate aperture and one or more deformable protrusions along the edge of the aperture. The tang is operably coupled to a buckle frame via a coupling member that extends through the aperture. Upon the application of a sufficient load to the tang, the coupling member deforms the protrusion(s), allowing the tang to move relative to the frame. Movement of the tang relative to the frame can move a colored load indicating region to a position that is visible through a window in a housing of the buckle assembly.

1. A buckle assembly, comprising: a frame having a first aperture;a tang having a second aperture, wherein the second aperture includes a first edge portion opposite a second edge portion, wherein the tang includes an inwardly facing protrusion on at least one of the first edge portion or the second
1. A buckle assembly, comprising: a frame having a first aperture;a tang having a second aperture, wherein the second aperture includes a first edge portion opposite a second edge portion, wherein the tang includes an inwardly facing protrusion on at least one of the first edge portion or the second edge portion of the second aperture, wherein the inwardly facing protrusion at least partially defines a first end portion of the second aperture and a second end portion of the second aperture; anda coupling member operably coupling the tang to the frame, wherein the coupling member extends through the first aperture in the frame and through the first end portion of the second aperture in the tang. 2. The buckle assembly of claim 1 wherein the tang is movable relative to the frame via deformation of the inwardly facing protrusion and associated movement of the coupling member from the first end portion of the second aperture to the second end portion of the second aperture, in response to a design-level load applied to the tang. 3. The buckle assembly of claim 2, further comprising an electrical switch mounted to the tang and operable to deactivate an occupant restraint system warning indicator when the coupling member extends through the first end portion of the second aperture. 4. The buckle assembly of claim 2, further comprising a visual load indicator coupled to the tang, wherein movement of the tang relative to the frame moves the visual load indicator from a first position to a second position to visually indicate the application of the design-level load on the buckle assembly. 5. The buckle assembly of claim 4, further comprising a housing having a window, wherein the visual load indicator includes a first portion having a first color and a second portion having a second color, and wherein the second portion is not visible through the window when the load indicator is in the first position, and the second portion is visible through the window when the load indicator is in the second position. 6. The buckle assembly of claim 1 wherein the second aperture comprises a figure eight shaped opening in the tang. 7. The buckle assembly of claim 1 wherein the second aperture is non-circular. 8. The buckle assembly of claim 1, further comprising: a switch operably coupled to the tang;a pawl pivotally mounted to the frame; anda pawl extension coupled to the pawl, wherein the pawl extension is operable to actuate the switch upon insertion of a web connector into the buckle assembly. 9. The buckle assembly of claim 1, further comprising a load indicator operable to provide an indication of the position of the coupling member within the second aperture. 10. A buckle assembly for releasably engaging a web connector, the buckle assembly comprising: a frame having a first aperture;a pawl pivotally attached to the frame and having a latch positioned to releasably engage the web connector;a tang having a second aperture that includes a first end portion and a second end portion, wherein the tang includes a first inwardly facing obstruction on a first edge portion of the second aperture and a second inwardly facing obstruction on a second opposing edge portion of the second aperture, wherein the first obstruction and the second obstruction are positioned between the first end portion and the second end portion; anda coupling member extending through the first aperture and the first end portion of the second aperture to secure the tang to the frame, wherein the obstructions are deformable under a design-level load to permit movement of the coupling member from the first end portion to the second end portion. 11. The buckle assembly of claim 10, further comprising a housing having a window, and a load indicator having a load indicating region, wherein movement of the coupling member from the first end portion of the second aperture to the second end portion includes movement of the load indicating region to a position adjacent to the window. 12. The buckle assembly of claim 10 wherein the second aperture includes a figure eight shape. 13. The buckle assembly of claim 10, further comprising an electrical switch positioned such that engagement of the web connector with the buckle assembly actuates the switch when the coupling member extends through the first end portion of the second aperture. 14. The buckle assembly of claim 13 wherein engagement of the web connector with the buckle assembly does not actuate the switch when the coupling member extends through the second end portion of the second aperture. 15. The buckle assembly of claim 13, further comprising a pawl extension coupled to the pawl, wherein the pawl extension is operable to actuate the switch via rotation of the pawl. 16. The buckle assembly of claim 10 wherein the design-level load is applied via forces acting on the tang and on the pawl. 17. A load indicating buckle assembly, comprising: a frame having a first aperture;a tang having a second aperture, wherein one of the first aperture and the second aperture is circular, and the other of the first aperture and the second aperture is elongated, and wherein inwardly facing protrusions on opposing edge portions of the elongated aperture at least partially define a first end portion and a second end portion of the elongated aperture; anda coupling member extending through the circular aperture and the first end portion of the elongated aperture to secure the tang to the frame, wherein the protrusions are deformable under a design-level load to permit movement of the coupling member from the first end portion to the second end portion. 18. The buckle assembly of claim 17, further comprising a pawl rotatably coupled to the frame, and a switch, wherein application of the design-level load includes movement of the switch from an actuable position to a non-actuable position. 19. The buckle assembly of claim 18, further comprising a pawl extension coupled to the pawl, wherein the pawl extension includes a contact feature positioned to engage the switch via rotation of the pawl. 20. The buckle assembly of claim 17, further comprising a load indicator having an indicating region, wherein application of the design-level load includes movement of the indicating region from a non-visible position to a visible position. 21. The buckle assembly of claim 17 wherein the coupling member includes a cylindrical central portion, and wherein the cylindrical central portion extends through the circular aperture and the elongated aperture.
