Abstract

According to one embodiment of the invention, a fitting system for a helmet is provided. The fitting system includes a belt having supported racks coupled to a belt adjustment device. The belt adjustment device is operable to allow a user to tighten the belt, and release the belt at a single touch of a release actuator. The belt adjustment device and the racks are configured to hug the occiput of a user when the helmet is properly worn. The belt adjustment device is also operable to hold the rear straps of the helmet apart but is not attached to the helmet. The belt defines a collapsible button for securing a pad. The pad defines a substantially lateral compressed strip that is operable to urge the pad against the belt. The belt adjustment device and the belt are configured to allow rear straps of the helmet to approximately directly approach the chin of the user.

Claims23

Dependent claims

An adjustment apparatus for a helmet, the helmet having a belt disposed inside the helmet, the belt having a first end portion and a second end portion that are coupled such that the belt forms a loop, the adjustment apparatus comprising:

a base having a first end and a second end, the base defining a first aperture at a first side and a second aperture at a second side of the base between the first and the second ends;
a channel defined in the base and extending from the first end to the second end, the channel configured to receive the first and the second end portions of the belt at the first end and the second end, respectively;
an adjuster positioned at least partly in the channel and configured to engage both the first and the second end portions of the belt, the adjuster operable to adjust the size of the loop by urging the first and second end portions along the channel in opposite directions, the adjuster at least partly protruding from the second aperture of the base;
a pawl positioned in the base proximate to the adjuster, the pawl operable to engage the adjuster to prevent a movement of the adjuster in at least one direction;
a release actuator coupled to the pawl via the first aperture of the base, the release actuator operable to disengage the pawl from the adjuster;
and
a hoop spring coupled to the pawl and operable to urge the pawl against the adjuster so that the pawl is engaged with the adjuster.

4 more elements

A system for fitting a helmet on a head of a user, the helmet having a first strap and a second strap anchored at a rear portion of the helmet, the system comprising:

a belt disposed at least partly in an interior of the helmet, the belt having a first curved rack gear and a second curved rack gear that extend toward the rear portion of the helmet, each of the first and the second curved rack gears having a side that is attached to a curved flange and a radius of curvature of approximately 16 inches, the belt defining a first hole and a second hole;
a rib positioned across the first hole;
a button suspended over the second hole by a pair of collapsible legs coupling the button and the belt, the button having a footprint that fits within the second hole;
a belt adjustment mechanism not directly attached to the helmet, the belt adjustment mechanism comprising:
a pinion gear engaged with the first and the second curved rack gears of the belt;
a wheel gear coaxially attached to the pinion gear;
a ratchet engaged with the wheel gear;
a release actuator coupled to the ratchet and positioned in a location separate from the wheel gear;
a first end slidably coupled to the first strap;
and
a second end positioned approximately 135 millimeters from the first end and slidably coupled to the second strap;
wherein the wheel gear is operable to incrementally urge the first and the second curved rack gears in opposite directions using the pinion gear by turning in a first direction, the ratchet is operable to prevent the wheel gear from turning in a second direction that is opposite from the first direction, and the release actuator is operable to disengage the ratchet from the wheel;
and
a pad defining a button hole, an compressed arcuated strip and a compressed strip having an approximately same orientation and width as the rib, the pad coupled to the button of the belt at the button hole and woven through the first hole and the rib, wherein the compressed strip of the pad underlies the rib, and the compressed arcuated strip is disposed approximately along the length of the pad.
