Abstract: A safety helmet (1) has a circumferential module ring (2), made especially of a thermoplastic plastic. The module ring (2), has a plurality of plug-in slots (3), which are located at spaced locations from one another in the direction of the module ring (2). This provides standardized simultaneous mounting possibilities for various functional accessories with plug elements complementary to the plug-in slots (3).

Abstract: This protective helmet comprises a rigid or semi-rigid external shell comprising a plurality of rigid or semi-rigid flaps joined together and a compressively deformable internal liner acting as a shock absorber, the latter also comprising several elements associated with said flaps. At least some of the flaps that constitute the external shell are capable of moving relative to each other at their respective means of connection and the elements that constitute the internal liner associated with the flaps in question are designed so that they retract inside the volume defined by the helmet during relative displacement of the corresponding flaps.

Abstract: Headgear of the type having an outer layer and a relatively flexible inner layer includes a belt which extends around the inner layer within the outer layer, and a tensioning device which can tension the belt causing the belt to urge the inner layer inward away from the outer layer and against the helmet wearer's head. Preferably, the tensioning device includes a chinstrap assembly releasably fastened to the front of the helmet.

Abstract: A shin guard includes a plate made of a rigid material sandwiched between two layers of flexible material, such as foam. The two flexible layers are attached to each other around a periphery of at least one of the flexible layers. The plate includes a center panel attached to only one of the flexible material layers. The plate also includes two side panels hingedly attached to the center panel so that the panels can move with respect to the center panel. The panels are not attached to either layer of flexible material so the panels can move with respect to both flexible material layers.

Abstract: The head cooling apparatus is housed in a case removably fitted within an existing hat crown of a hat, without structural modification to the hat. The case has a plurality of air vents including an intake and a trio of vents which direct air across a hat wearer's head. The fan within the case is adjacent to the intake. The non-evaporative refreezable cooling cartridge is removably fitted within the case. The switched power source within the case is in communication with the fan and a power source. The fan forces air into the intake, across the cooling cartridge and out the vents toward a wearer's head.

Abstract: A chin pad assembly and method of construction thereof provides an outer shell of plastics material having straps attached thereto and an inner cushion member attached to the shell independently of the straps. The shell has an outer surface and an inner surface providing a pocket with a pair of openings formed in the shell between the outer and inner surfaces. The inner cushion member is received in the pocket of the shell and provides a pocket to receive a wearer's chin. An attachment mechanism has a pair of elongate members extending from an outer surface of the cushion member. Each of the elongate members is received through a separate one of the openings in the shell and coupled outwardly from the outer surface of the shell to releasably attach the cushion member to the shell independently of the straps.

Abstract: A covering for a sports helmet is provided. The covering including a band having at least a portion composed of a first heat shrink material. The band being sized to cover the sports helmet after an application of heat to the first heat shrink material. Also provided is a sports helmet.

Abstract: In a protective helmet, especially a bicycle helmet, having a head band made of plastic, which is fastened to the helmet calotte and which is height adjustable for adapting to the head anatomy of the wearer, provision is made that the head band is supported on both sides of the helmet calotte so as to be pivotable and that extensions are provided that extend at both end regions of the head band approximately perpendicular to the same toward the top and interior of the helmet, which engage into holding elements that are fixed in the helmet calotte, the extensions being adjustable lengthwise relative to the holding elements.

Abstract: A suspension system and chin strap assembly for a helmet including two downwardly extending top straps; strap adjusters coupled proximate the end portions of each top strap; a helmet attachment means coupled to each of the top straps; a headband coupled to each of the top straps; a front strap that is adjustably coupled to a first front strap adjuster and a second front strap adjuster; a nape pillow pad is coupled to the front strap, and a portion of a quick release buckle and a strap ring are slideably coupled to the front strap; a chin strap coupled to the quick release buckle and a strap ring; and a back strap that is adjustably coupled to a first back strap adjuster and a second back strap adjuster and attached to a nape pillow pad.

Abstract: A replacement pad kit for use in an Advanced Combat Helmet (ACH) system helmet comprises a plurality of replacement pads for disposition within an ACH helmet. At least one of the replacement pads comprises a fabric layer for contacting the skin of a wearer, an anti-bacterial hydrophilic foam layer, a shock absorption SRF foam layer, and a hook and loop fastener material for engaging some of the plurality of pad receiving hook and loop type fasteners.

Abstract: An apparatus including an inner face, an outer face coupled to the inner face, an opening for receiving a hand of a wearer, and means for separating the pocket created by the coupling of the inner and outer face such that the apparatus fits securely around the wearer hand. A thumb covering is connected to the apparatus in order to allow the wearer to fully use an opposable thumb.

Abstract: A wind rectifying member positioned between two ventilation covers on the top of a helmet is adjustably supported by fitting members of support structures mounted within each ventilation cover. The fitting members adjust the forward and rearward positioning of the rectifying member and its angle of tilt relative to the wind direction. The fitting members extend through openings in facing side walls of the ventilation covers and into indentations in the ends of the rectifying member.
