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 helmet has a helmet shell and a visor pivotally connected to the helmet shell. The helmet further has an electrical device attached to the visor. First and second helmet electrical contacts are attached at both sides of the helmet and are adapted for electrically connecting to an electrical power source. First and second visor electrical contacts are attached to each side of the visor and are electrically connected to the electrical device. The first and second visor electrical contacts are pivotally connected to the helmet shell about first and second pivot axes passing through the first and second helmet electrical contacts respectively. The first and second visor electrical contacts are in contact with the first and second helmet electrical contacts respectively, at all positions of the pivoting visor.

A helmet has a helmet shell, a visor connected to the helmet shell, an electrical device attached to at least one of the helmet shell and the visor, and an electrical connector assembly. The electrical connector assembly has a flexible member having a first end magnetically connected to the helmet shell, which is electrically connected to the electrical device. The electrical connector assembly also has a connector connected to a second end of the flexible cord that is electrically connected to the electrical device via the flexible cord. The connector is adapted to connect to a power source.

A protective system including: a protective suit capable of withstanding the force of an impact without tearing, the protective suit including: a head portion; a neck portion connected to the head portion; a torso portion connected to the neck portion; a fluid bladder formed in at least two of the head portion, neck portion and torso portion, the fluid bladder containing a fluid; and an alert indicator for indicating when the force of an impact on the fluid bladder exceeds a predetermined threshold.

A system is disclosed for attaching a bump cap to a welding headgear. The system includes a bump cap, and an attachment member. The attachment member is configured to attach the bump cap to a welding headgear.

A helmet includes a shell having an interior surface and a padding configured to provide progressive impact resistance. The padding includes a first padding layer and a second padding layer. The first padding layer has a first side configured to conform to the interior surface of the shell and an opposing second side that defines a plurality of first continuous extensions arranged in a spaced configuration defining a plurality of first recesses therebetween. The second padding layer has a third side configured to conform to a head of a wearer of the helmet and an opposing fourth side that defines a plurality of second continuous extensions arranged in a spaced configuration defining a plurality of second recesses therebetween.

A helmet includes a shell having an interior surface, a padding disposed along the interior surface of the shell, and a chinbar. The padding defines a first engagement surface positioned at a first lateral side of the padding and a second engagement surface positioned at an opposing second lateral side of the padding. The chinbar includes a cage, a first flange, and a second flange. The cage includes a first end defining a third engagement surface and a second end defining a fourth engagement surface. The third engagement surface interfaces with the first engagement surface and the fourth engagement surface interfaces with the second engagement surface. The first flange extends from the first end of the cage. The second flange extends from the second end of the cage. The first flange and the second flange of the chinbar are embedded within the padding.

A motion restrictor device is wearable with a helmet to reduce the risk of head or spine injury caused by injurious movement of the helmet. The device includes a harness wearable by a user of the helmet and a helmet-engaging component supported on the harness. The helmet-engaging component presents laterally spaced apart, fore-and-aft extending helmet-engagement surfaces positioned on opposite sides of the neck of the user when the device is worn.

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.
