The present invention provides a safety gear for cycling comprising a cycling gear, a turn signal component, a turn signal component circuit comprising a turn signal switch, a brake signal component, a brake signal component circuit comprising a brake signal switch. The turn signal switch and the brake signal switch can sense the roll and pitch motion of a cyclist's head to control the on or off of the turn signal component and the brake signal component respectively. This present invention allows the cyclist to keep both of his hands on the handle bar throughout a whole journey to maintain balance and control of bicycle, even though the cyclist needs to turn on the corresponding signals.

A helmet comprising and outer liner and an inner liner slidably coupled to an interior surface of the outer liner is disclosed. The outer liner comprises an interior surface and the inner liner comprises an exterior surface. The inner liner is composed of an elastically deformable material. A majority of the interior surface of the outer liner and a majority of the exterior surface of the inner liner are both substantially parallel to a pseudo-spherical surface having a coronal cross section that is circular with a first radius and a sagittal cross section that is circular with a second radius different from the first radius. The inner liner is elastically deformable along the interior surface of the outer liner in response to rotation of the outer liner relative to the inner liner caused by an impact to the helmet.

A protective helmet may include an energy management material inside an outer surface, a rim positioned on an outwardly facing surface between an inner surface and the outer surface, a sweat management pad assembly with an absorbent forehead pad positioned in a front portion of the helmet proximate the rim, the assembly including at least one absorbent extension tab extending from the absorbent forehead pad and across a portion of a surface of the rim outward of the inner surface of the energy management material, wherein the absorbent extension tab extends at least half a distance across the rim between the inner surface and the outer surface, and a fastener positioned between the absorbent extension tab and the rim and coupling the absorbent extension tab to the rim.

Helmet with visor having a shell structure shaped is to at least partly cover the user's head. The visor is hinged to the opposite sides of the shell and mobile with respect to the shell between a raised position and a lowered position where it provides a protective extension of the helmet at the eyes of the user. The visor is manually switchable from the raised and lowered positions by using a magnetic coupling between the visor and the shell which guides and keeps the visor stable in the raised and lowered position and in a plurality of intermediate positions.

The disclosure relates to a bone conduction-based Bluetooth wireless riding helmet comprising a helmet body, a regulator at an interior of the helmet body, a brim at a front end of the helmet body, and a drawstring connecting two sides of a bottom of the helmet and the drawstring is fixed on the helmet through a quick release buckle; wherein an interior of the helmet body is provided with a removable bone conductor that is electrically connected with a power system and a control system; wherein the control system is electrically connected with a regulating device on the drawstring. The disclosure has the following beneficial effects. On the bone conduction-based helmet, a bone conduction-based vibrator sound source is embedded on each side of the helmet and perfectly integrated with the helmet, so that sounds can be clearly heard even when both ears of a rider are covered and even when it is used in a noisy environment.

A safety helmet with retractable brim comprising a helmet shaped body having a slot presented on a downward facing surface of a front section. The safety helmet includes a brim that translates within the slot between a retracted and a downward configuration. In the retracted configuration the brim is received within the slot. In the downward configuration the second end of the brim does not extend beyond the forward facing surface of the helmet. A pivoting element is configured to pivotally couple the brim proximate to the lip of the slot. The pivoting element allows the brim to move between the downward configuration and a forward configuration. In the forward configuration the brim extends outward beyond a forward facing surface of the helmet shaped body. A first locking element is configured to maintain the brim in the forward configuration.

A composite geometry structure for the absorption and dissipation of the energy generated by an impact includes a plurality of hollow cells, adjacent and stably connected to each other. On each cell there are identified one or more arc elements which develop starting from two juxtaposed areas of the same perimeter edge of the cell, such arc elements being configured to be elastically deformed.

A helmet, in particular to a bicycle helmet, having a plurality of ventilation openings and at least one evaporation cooler that is arranged in a ventilation opening.
