Poorly fitting sports helmets can transmit impact to the head; a conforming silicone gel liner absorbs and distributes energy inside the shell.
An aperture, resilient wiper, and alignment feature keep sunglasses or goggles attached to a bicycle helmet when not in use.
A movable cover hides removable chin-guard mounts, blocking dirt and moisture while preserving helmet aerodynamics and reducing noise.
A helmet inflatable chamber uses a torso-mounted inflator to protect the neck without adding bulky hardware inside the helmet.
A semi-rigid chin strap uses incremental adjustment and pivoting to improve helmet fit while moving into a retained storage position.
Elastic members unfold a honeycomb or bellows protection unit around the head, enabling impact absorption and repeated use without inflation hardware.
Anchoring points tension a simplified liner into the helmet’s curved interior while preserving ventilation and easing replacement.
Rotatable adjustment members reposition the headband for sagittal and circumferential fit while keeping the helmet frame close to the user's head.
Interchangeable nesting pods and a load distribution plate spread impact forces while adapting helmet fit to different head sizes.
A soft edge protector cushions helmet visor contact, safeguarding the nose and chin from abrasion-induced cuts while preserving visibility.
An articulated cheek plate extends hard-hat coverage to the face sides and chin, while a clamp secures it against the visor.
Breakaway shear connections let the outer helmet layer move at impact while honeycomb tubes absorb energy and preserve airflow.
Fluid bladders redistribute impact pressure across helmet, neck, and torso sections while conditioning body temperature to address concussion and hyperthermia risks.
An alveolar frontal band uses closed-bottom cells and openings to improve forehead airflow and limit sweat reaching the face.
A resilient wiper in a helmet aperture engages an eyewear arm to prevent sunglasses or goggles from being lost when not in use.
Modular pads dissipate impact forces while internal sensors capture force, direction, and location data for real-time helmet monitoring.
A support plate nests in a racing-suit pocket and tethers the helmet, restraining the head and neck without a bulky external device.
