Head Rests TRIZ Cases
- Movable Headrest with Spring-Loaded Tail Extension
A spring-loaded tail extension maintains a gapless surface between the headrest and backrest for children of varying heights.
- Vehicle Headrest Foam Connecting Part Design
A vehicle headrest uses a pour-in-place foam connecting part to join the mounting bracket.
- Car Seat Headrest Wing Energy Absorption
Layered foams and crush plates in a headrest wing structure disperse side impact energy while maintaining structural strength.
- Vehicle Headrest with Drowsiness Alarm and Whiplash Prevention
A vehicle headrest integrates a drowsiness alarm system and vibration mechanism to support the driver's head.
- Headrest Control Apparatus with Lateral Sliding Locking Mechanism
A headrest control apparatus uses a lateral sliding second fixing member to adjust position without continuous pushing.
- Headrest Guide Shaft Eccentricity Management
Differential guide shaft gaps absorb eccentricity, maintaining rigidity while reducing wear and rattling.
- Collapsible Headrest With Flexible Membrane for Stowage
A collapsible headrest uses a flexible membrane and wedge members to expand or compress its thickness for stowage within a seat back.
- Polyamide-Polyethylene Resin Composition for Vehicle Parts
A polyamide-polyethylene resin composition incorporates ultra-high molecular weight siloxane and inorganic fillers to enhance surface durability.
- Vehicle Seat Headrest Connector Mounting Structure
Merged seatback frame holder eliminates separate components, reducing installation time and complexity.
- Elastic Bearing Device for Vehicle Headrest Rod
An elastic bearing device compensates for dimensional tolerances in vehicle headrest support rods, preventing rattling.
- Head Restrastry Fins Transfer Energy to Vehicle Glass
Bracket fins extend through the headrest bun to break vehicle glass, dissipating energy while maintaining compact interior space.
- Dynamic Damper Headrest with Segmented Attachment for Front-Rear Vibration Control
A headrest dynamic damper uses a segmented attachment member to fix an elastic member along its perimeter, enabling weight displacement in the front-rear direction.
- Movable Visor for Head Restraint Display Glare Reduction
A movable visor shields a head restraint display from glare and environmental debris, resolving the trade-off between protection and viewing accessibility.
- Movable Headrest Assembly with Pivotable Side Impact Portions
Pivotable side impact portions on a movable headrest assembly eliminate seat obstruction for taller occupants while maintaining child safety protection.
- Vehicle Headrest Two-Point Contact Whiplash Protection
A vehicle headrest uses a two-point contact system to stabilize the occupant's head during impact events.
- Leaf Spring Bearing for Vehicle Headrest Height Adjustment
A leaf spring bearing with a low friction layer biases the headrest inner member against the seat back outer member.
- Power Articulating Headrest Assembly with Foldable Linkages
Segmentation and nesting principles allow a power articulating headrest to fold for compact shipping while maintaining multi-directional adjustment.
- Integral Headrest Frame with U-Shaped Rod Assembly
An integral single-frame headrest inserts a U-shaped rod into a hollow cavity to resolve strength versus manufacturing complexity trade-offs.
- Vehicle Seat Headrest Locking Mechanism Offset Suppression
Segmenting locking and stopper functions resolves offset transformation under impact, eliminating high part accuracy requirements.
- Headrest Functional Module Integration via Elastic Fastening
Elastic fastening clips secure the module to reduce noise while meeting ECE 17 stability criteria.
- Ratchet Headrest for Reduced Impact and Whiplash
A mechanical headrest uses a ratchet mechanism to translate toward an occupant's head during collision, providing dynamic cushioning without electronics.
- Headrest Folding Device Ratchet Mechanism
A headrest folding device uses a ratchet mechanism to transfer operation force from a release lever to a lock link.
- Automotive Headrest Modular Cover Assembly
Segmented covers eliminate textile folding in overlap regions, simplifying manufacturing.
