They actually aren't helmets, they're called DOC Bands, and they help to reshape their heads. Lila's head is really flat in the back and Jack's ears are about an inch out of alignment with each other and his eyes are not even close to being parallel.
A hockey helmet is worn by players of ice hockey and inline hockey to help protect the head from potential injury when hit by the puck, sticks, skates, boards, other players, or the ice.
Hockey helmets grip the head from inside by cupping the back of head, or the occipital protuberance. Helmet manufacturers will have a chart that relates their helmet sizes to head measurements.
Quints is a 2000 Disney Channel Original Movie starring Kimberly J. Brown as the older sister of a set of quintuplets.
Jamie Grover (Kimberly J. Brown) is an only child who resents the constant attention her parents give her. Her wish is finally granted when her mother becomes pregnant. When her mother gives birth to quintuplets, Jamie's life changes dramatically. She discovers she might not want the same things her parents want for her, but nonetheless, her parents focus all of their attention on her baby brothers and sisters (Adam, Becky, Charlie, Debbie, and Eddie). When Adam becomes terribly ill, she discovers that she really doesn't mind the babies, and that she does have the courage to let her parents know she has dreams of her own.
A helmet is a form of protective gear worn to protect the head from injuries.
Ceremonial or symbolic helmets (e.g., UK policeman's helmet) without protective function are sometimes used. The oldest known use of helmets was by Assyrian soldiers in 900BC, who wore thick leather or bronze helmets to protect the head from blunt object and sword blows and arrow strikes in combat. Soldiers still wear helmets, now often made from lightweight plastic materials.
Personal protective equipment (PPE) refers to protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. "Protective clothing" is applied to traditional categories of clothing, and "protective gear" applies to items such as pads, guards, shields, or masks, and others.
The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it does not eliminate the hazard at source and may result in employees being exposed to the hazard if the equipment fails.
