A training apparatus, system and method for teaching proper athletic technique in contact sports. A first strap portion may be attached to a football helmet, and a second strap portion attached to shoulder pads. The apparatus provides feedback on the user's technique as tension is applied to the first and second strap portions, for example when the user attempts to lower their head during tackling or blocking, and causing detachment upon exceeding a threshold detachment force.

The invention is intended to protect football players, race car drivers and others. An apparatus that dampens impacts and prevents rapid movement of user's head protected by helmets. Two embodiments are disclosed using piston configuration. In one embodiment, the piston is moving inside a housing filled with a viscoelastic fluid and the other is a locking piston dampener mechanism.

An energy absorbing protective material includes an encapsulating layer defining two or more pouches, which define an internal closed cavity. A frangible glass foam material may be located within the cavity and configured to absorb an impact force upon the pouch. A non-frangible material may also be located within the cavity adjacent at least a portion of the frangible foam glass material. The encapsulating layer may include vinyl, rubber and/or plastic. The non-frangible material may include padding, rubber, polyurethane, polystyrene, and/or expanded polystyrene.

Systems and methods for selectively attaching an accessory mount to a helmet are disclosed. A carrier may be used to position the accessory mount on the helmet. The accessory mount may be positioned on the helmet without engaging the rim of the helmet. The carrier may be compatible with various accessory mounts to permit mounting of different accessories. The accessory mount may be a powered mount for attachment to a Night Vision Device (NVD) such as Enhanced Night Vision Goggles (ENVG), or the accessory mount may be a non-powered accessory mount.

A helmet that includes vents in the shell and removable plugs that may be positioned in the vents to provide an airtight seal while maintaining the aerodynamic shape of the helmet. The vent has an outer vent opening in the outer wall surface of the shell and an inner vent opening in the inner wall surface of the shell. The plug includes a resilient lower surface and an upper surface opposite the resilient lower surface. The resilient lower surface has a lower peripheral lip that compresses when the plug is pushed through the outer vent opening and the inner vent opening and that subsequently expands after the lower peripheral lip passes through the inner vent opening so that the lower peripheral lip engages a portion of the inner wall surface of the shell. The upper surface has an upper peripheral lip configured to conform to a portion of the outer wall surface of the shell when the plug is inserted in the vent.

The present invention is directed to a helmet wearing determination system including a imaging means that is installed in a predetermined position and images a two-wheel vehicle that travels on a road; and a helmet wearing determination means that processes an image imaged by the imaging means, estimates a rider head region corresponding to a head of a person who rides on the two-wheel vehicle that travels on the road, compares image characteristics of the rider head region with image characteristics according to the head at a time when a helmet is worn or/and at a time when a helmet is not worn, and determines whether or not the rider wears the helmet.

A horse training goggle assembly includes a pair of goggles that may be worn by a jockey riding a horse during race training. The goggles have a frame and a lens that is removably positioned in the frame. A tracking unit is coupled to the goggles and the tracking unit is in electrical communication with a global positioning system (GPS) to identify a physical location of the jockey. Moreover, the tracking unit calculates a speed and direction of the horse during the race training. A display is embedded within the lens and the display is visible to the jockey when the goggles are worn. The display displays indicia in the lens and the display is electrically coupled to the tracking unit to display data relating to the speed and direction of the horse. A communication unit is coupled to the goggles for verbal communication between the jockey and the trainer.

Disclosed is a helmet with neck protection, which comprises a helmet shell, a collision displacement sensor disposed in the helmet shell, a gas generator disposed at an inner side of a lower rim of the helmet shell, an airbag stored in the lower rim of the helmet shell. The gas generator is connected to the airbag. The collision displacement sensor is connected to the gas generator through a restraint control module and a wire in order for the gas generator to release gas to inflate the airbag when the collision displacement sensor senses danger, therefore the airbag forms an air curtain falling down to protect the cervical vertebra. The airbag is folded and hidden in the helmet and is opened to fall down to form an annular air curtain under dangerous circumstances to stand against the shoulder to support the helmet to reduce the pressure caused to the neck.

A protective helmet has an outer shell configured for surrounding a head of a user and at least one accessory attachment rail connected to the outer shell. The accessory attachment rail has a body having a front end, a rear end, and one or more slots between the front end and the rear end. Each of the one or more slots is configured for removably receiving at least one helmet accessory. A locking mechanism is associated with each of the one or more slots for automatically locking the at least one helmet accessory in the one or more slots upon insertion of the at least one helmet accessory within the one or more slots and for preventing removal of the at least one helmet accessory from the one or more slots. At least one connection element is provided for connecting the accessory attachment rail to the outer shell.
