Belt Retractors TRIZ Cases
- Vehicle Seat Impact Absorber with Rotating Base and Deformable Member
A vehicle seat impact absorbing device uses a deformable member between rotating base members to absorb collision energy.
- Seat-belt retractor magnetic flux guide for sensor placement
Stationary magnetic flux guide channels field variations from rotating element to distant Hall sensor, resolving assembly constraints.
- Belt Retractor Switchable Force-Limiting Coupling Mechanism
A belt retractor coupling element uses a bridging device to delay locking hook engagement until a preset rotation angle.
- Safety Belt Heating Assembly with Integrated PCB Protector
Heating assembly integrated into tubular webbing with dual printed circuit boards secured in a protective housing.
- Twin Shoulder Strap Harness RetraCTOR With Intermediate Shaft Load Distribution
An intermediate shaft couples twin webbing spools to dynamically distribute impact loads, reducing chest deflection during off-center collisions.
- Seat Belt Retractor Inertial Sensor Vibration and Contamination Protection
Magnetic force constrains the movable mass within a sealed sensor chamber, preventing premature lock-up caused by vehicle vibration and mud contamination.
- Vehicle Seatbelt Control Device Buckle State Detection
A vehicle seatbelt control device detects buckle switch states to manage belt tension and storage operations efficiently.
- Worm Gear Helix Angle Optimization for Thrust Force Management
Optimizing worm gear helix angles redirects axial thrust to the frame, eliminating heavy case reinforcement and reducing seat belt retractor weight.
- Seatbelt Control Device Load Switch Timing
A seatbelt control device manages pretensioner activation and force limiter load settings through real-time collision detection.
- Segmented Passenger Restraint Housing for Vehicle Safety Compliance
Segmenting the restraint housing frame allows integrated mounting brackets to meet safety compliance without increasing device complexity.
- Seat-belt pretensioner coupling element release mechanism
Shaft rotation disengages the pretensioner drive wheel, eliminating ready positioning and reducing axial stress on the coupling element.
- Webbing Take-Up Cover Member Radial Displacement Suppression
An opposing suppressing portion prevents outward displacement of a webbing take-up cover member caused by spiral spring urging force.
- Perpendicular Motor Webbing Take-up Device for Compact Seatbelt Retractor
Positioning the motor between leg plates with a perpendicular shaft reduces volume and weight while maintaining clutch access.
- Helical Gear Unit for Compact Seat Belt Tensioner Design
A helical gear unit connects the electric motor to the drive wheel in a reversible seat belt tensioner.
- Belt Tensioner Plastically Deformable Stop Sealing
A belt tensioner uses a plastically deformable stop to create reliable piston sealing contact.
- Seatbelt Retractor Fluid Damping for Reusable Load Limiting
A seatbelt retractor uses a piston and damping fluid to absorb inertia energy during vehicle impacts.
