What it is Filled
A hockey helmet is protective headgear worn in ice hockey and related forms of hockey, typically combining a rigid outer shell, an impact-attenuating liner and a retention system to reduce head injury risk from impacts.
In scope
- Helmet shell, impact-management liner and head coverage
- Sizing, adjustment and retention systems
- Interfaces with cages, visors and other documented accessories
- Product identification, certification evidence and use restrictions
- Inspection, care, impact history and retirement decisions
Out of scope
- Standalone cages, visors and mouthguards beyond their helmet interfaces
- Goalkeeper masks as a distinct protective equipment kind
- Medical diagnosis or treatment of head injuries
- Hockey rules beyond requirements governing helmet use
- Manufacturer product lines and individual helmet records as separate catalogue kinds
Why it exists Filled
Enable an agent to recognise a hockey helmet, assess its fit and service condition, and determine whether its documented configuration is suitable for an intended hockey activity.
Distinguishing features Filled
- Documentation identifies hockey as an intended activity; resemblance to a skating or cycling helmet is insufficient.
- The headgear combines a protective shell, an impact-management interior and a means of retaining it on the head.
- A cage or visor alone is face protection and does not constitute a hockey helmet.
- A helmet fitted with a cage must be distinguished from a purpose-built goalkeeper mask using its construction and manufacturer designation.
- The registered kind must be distinguishable from a named commercial model, a size variant and a serialised physical unit.
What robots and AI may and may not do Filled
Must not
- Approve a cracked, modified or uncertified helmet for play.
- Advise painting, drilling or adding parts that the maker says void certification.
- Share a player's concussion or medical history beyond those entitled to it.
Only with a human decision
- Clearing a player to return after a suspected concussion.
May
- Inspect a hockey helmet for cracks, loose fittings, worn liners and expired certification.
- Help a player find the correct size and fit using the maker's guidance.
Moral aspects Filled
- Head injuries in hockey can cause lasting brain damage, especially in young players.
- Pressure to keep playing leads people to hide symptoms.
Who is affected
- Players, including children
- Parents and coaches
Owners Filled
Steward
The player or team that owns it; the league sets equipment rules.
