Methods, apparatus, systems and articles of manufacture are disclosed including6 a connector for a flexible substrate including a first connector piece including a first plurality of through holes and a second connector piece including a second plurality of through holes, the second connector piece disposable in opposition to the first connector piece to align the first plurality of through holes and the second plurality of through holes to define, via the first plurality of through holes and the second plurality of through holes, a grommet and a plurality of fastener receivers. The connector also includes a channel, defined at least in part by the first connector piece, extending across the first connector piece.

A resilient clip can be used for covers for equipment. The resilient clip has a portion that can be inserted into a channel on the equipment, a portion that can be attached to a cover, and a portion that can be used to remove the clip from the channel.

An adjustable-length tensile member, for example, a strap for a wearable pack, can include a fastener member defining first and second apertures and a cross-member positioned therebetween. A strap can extend through the first aperture in a first direction, over the cross-member and through the second aperture in a direction opposite to the first direction. A cover plate can matingly engage with the fastener member to obscure a segment of the strap from view. Wearable packs can incorporate such adjustable-length tensile members. Methods for assembling such adjustable-length tensile members are also disclosed.

A container includes a pair of flaps, which can be brought close to one another, one of the flaps having a buttonhole; and a clasp designed to get through the buttonhole. The clasp includes an anchoring portion, which is fixed to the other one of the flaps; a wide portion, which is designed to prevent the clasp from moving apart from the buttonhole; and an intermediate connection portion, connected, through a pair of hinges, to the anchoring portion and to the wide portion, respectively. The wide portion and the anchoring portion are configured to rotate relative to the intermediate portion, so that the clasp is able to assume a plurality of operating conditions. The buttonhole is designed to interact with the clasp based on the operating condition assumed by the clasp, allowing the flaps or walls be brought close to one another or preventing them from moving apart.

A panel system includes a tab panel having at least one tab extending therefrom. The tab panel has a core and a facesheet adjacent the core. The panel system includes a slot panel having at least one slot receiving the corresponding tab of the tab panel therein. The slot panel has a core and a facesheet adjacent the core. The panel system includes a clip positioned between the tab panel and the slot panel. The clip is at least partially received in the slot. The clip has a tab panel securing member being secured to the tab panel and the clip has a slot panel securing member being secured to the slot panel. The clip securely joins the tab panel to the slot panel.

A football helmet includes a plastic shell with side regions having an ear flap with a face guard connector, an ear opening, a slot, and a snap connector. The helmet also includes an internal padding assembly removably connected to the plastic shell and including a jaw pad with a force attenuating layer. When the helmet is worn, a front edge of the jaw pad is positioned both in front of a coronal plane and below a basic plane of a head of the helmet wearer. A chin strap assembly releasably secures the helmet to the wearer and includes a lower flexible strap extending outwardly from each side of a central protective member. When the helmet is worn, an extent of the lower flexible strap is received by the slot when said strap is affixed to the snap connector. The shell also includes a raised central band integrally formed as part of the shell and extending across the crown region to the rear region. An arrangement of elongated vent openings flank the raised central band.

A locking retainer can include a strap that at least partly bounds an internal area and includes a locking arm with a locking pin that extends into the internal area and a release tab extending opposite the locking arm and away from the internal area. The strap can have a locking configuration in which, with a slidable support within the internal area, the locking pin extends into two locking apertures to lock the slidable support at a fixed length. The locking tab can be moved towards the internal area to move the strap into an unlocking configuration in which the locking pin is removed from the internal area to release the locking pin from the two locking apertures.

A spring clip includes a first frangible feature extending between a first cantilever bar and a support post and a second frangible feature extending between a second cantilever bar and the support post. The frangible features provide a readily perceived indication of proper spring clip installation.

A system and method including a a fastener clip assembly including a tub configured to engage and be secured to a slot in a chassis. The tub is configured to be secured to the slot bases at least upon the tub comprising two or more tabs. The tabs are attached to the tub along a top portion of each of the tabs, and each of the tabs are configured to bend along the top portion of the tabs. Each of the tabs are configured to bend in response to the tub being inserted into the slot and to bend back to original positions of each of the tabs. Bottom portions of each the tabs secure the tub to the slot.

A football helmet includes a plastic shell with side regions having an ear flap with a face guard connector, an ear opening, a slot, and a snap connector. The helmet also includes an internal padding assembly removably connected to the plastic shell and including a jaw pad with a force attenuating layer. When the helmet is worn, a front edge of the jaw pad is positioned both in front of a coronal plane and below a basic plane of a head of the helmet wearer. A chin strap assembly releasably secures the helmet to the wearer and includes a lower flexible strap extending outwardly from each side of a central protective member. When the helmet is worn, an extent of the lower flexible strap is received by the slot when said strap is affixed to the snap connector. The shell also includes a raised central band integrally formed as part of the shell and extending across the crown region to the rear region. An arrangement of elongated vent openings flank the raised central band.
