Helmet fit system and methods

A fit adjustment system for a helmet defining a helmet cavity, comprising:

• a flexible member comprising a flexible layer, the flexible layer comprising a transverse segment extending between a first lateral vertex and a second lateral vertex, a first oblique segment, and a second oblique segment, wherein the first oblique segment and the second oblique segment meet at an upper vertex, wherein the first oblique segment meets the transverse segment at the first lateral vertex, and wherein the second oblique segment meets the transverse segment at the second lateral vertex;
• an attachment member fixed to the flexible member at an attachment location and configured for attaching the flexible member to the helmet;
• a lace;
• and a lace tightening assembly attached to and supported by the flexible member and operatively associated with the lace, wherein the lace tightening assembly comprises an elongate housing fixed to the flexible layer, the elongate housing comprising a dial seat configured to accommodate a dial of the lace tightening assembly, the elongate housing further comprising a pair of arms integrally formed with, and extending from opposite sides of, the dial seat, wherein each arm includes one or more lace guides for routing the lace along a length of the flexible member, and wherein the transverse segment, the first oblique segment, and the second oblique segment define an opening therebetween in the flexible layer.

A fit adjustment system for a helmet defining a helmet cavity, comprising:

• a first flexible layer formed of an elastomer and a second flexible layer joined to the first flexible layer to form a two-layer structure, a lower portion of which extends below a bottom edge of the helmet when the helmet is worn, and wherein the two-layer structure is sufficiently flexible for repeated folding into the helmet's cavity when not worn, the first flexible layer comprising a transverse segment extending between a first lateral vertex and a second lateral vertex, a first oblique segment, and a second oblique segment, wherein the first oblique segment and the second oblique segment meet at an upper vertex, wherein the first oblique segment meets the transverse segment at the first lateral vertex, and wherein the second oblique segment meets the transverse segment at the second lateral vertex;
• an elongate housing comprising a dial housing fixed between the first and second flexible layers and defining a dial seat which is exposed through a dial opening in the first flexible layer, the elongate housing further comprising first and second arms extending in opposite directions from the dial housing;
• and a lace-tightening system operatively associated with the dial housing and comprising a dial rotatably coupled to the dial seat and at least one lace engaged with the dial, wherein the lace is routed through at least one pair of left and right lace guides protruding through the first flexible layer, each of the left and right lace guides located on an opposite side of the dial, each of the left and right lace guides included in a respective one of the first arm or the second arm, and wherein the transverse segment, the first oblique segment, and the second oblique segment define an opening therebetween in the first flexible layer.
