Vehicle Safety Belts TRIZ Cases

A spring-preloaded blocking lever and projection stabilize electrical seatbelt locking, reducing noise and avoiding orientation-dependent complexity.

Modular guide blocks let a safety belt tensioner change cable deflection angle or direction without redesigning the full assembly.

Complementary cap receiving areas guide and latch the plug housing, enabling error-free electrical blocking connection without line stress.

An electromagnet and second spring let the blocking lever engage the control disc quickly without axis alignment, cutting lock time and noise.

A pyrotechnic hook retracts the seatbelt lap webbing during impact to improve occupant kinematics and maintain buckle engagement.

Resilient upper and lower sleeves linked by a strap keep seatbelt webbing and the tongue aligned while resisting twist near the buckle.

A linear guide block routes the tension cable parallel to piston travel, expanding seat belt tensioner mounting options while stabilizing assembly.

A deflector shield and sealing ring contain hot pretensioner gas, maintain cylinder pressure, and preserve seat belt restraining force.

A detachable harness and booster seat improve child belt fit, portability, and protection across different user sizes and vehicles.

Stationary sleeve guides piston to prevent compressed gas escape through cable bushing, ensuring efficient tensioning.

Relocating the sealing member to an intermediate accommodation portion prevents gas leakage without enlarging the gas passage, suppressing pressure loss.

A lockable spool device secures a strap running-end at a selectable length using an axel and spring mechanism.

Radial wire positioning prevents interference during spool rotation, enabling longer energy absorbing strokes for vehicle occupant restraint.

An arrangement member moves an operation member to instantly switch a seat belt retractor from automatic locking to emergency locking without winding webbing.

A vehicle dynamics control system adjusts intervention intensity based on surroundings sensor data to prevent lateral breakaway.

A webbing winding device lock unit uses a spring tab and ratchet teeth to engage the mechanism without biasing springs.

Fixed hook portion anchors segmented guide member to prevent engagement loss between pinion and balls, ensuring efficient rotation.

A seat belt retractor uses a variable torsion bar to manage webbing tension during collision events.

A belt retractor integrates a sensor immobilization mechanism with its planetary gear assembly to manage child safety activation.

Axial insertion of a fixing component reduces torsion shaft length while a high-rigidity washer prevents deformation during assembly.

Mounting the control disc on the cover cap eliminates axial tolerance and wobbling that disrupts sensor lever engagement reliability.

A hollow belt shaft connects a load limiting device to a tensioning unit, reducing interference between devices.

Dynamic vehicle spacing optimizes radiator air flow, reducing fan power demand and fuel consumption.

A seat belt accessory uses a deformable connecting member to adjust spacing between the strap and passenger.

Extracted bushing shields cable from hot gas, simplifying housing design and sealing complexity.

A bayonet connector device with interlocking male and female engagement structures provides secure rotational locking for vehicle occupant restraint systems.
