Safety Belts TRIZ Cases

Sensors measure lifeline distance and trigger a drum stopper to apply friction, preventing falls by constraining cable extension beyond safe working distances.

Segmenting the ventral attachment zone from the dorsal closure prevents accidental detachment while allowing easy donning.

A pivot arm linkage adjusts harness separation to free rear rider hands while maintaining stability.

Rear-mounted counterweights guide along ladder sides via pulleys, preserving climber space without platform modifications.

A lineman harness adapter uses a three-point back attachment to distribute weight evenly across the user's torso.

Identical flanges pivot 180 degrees along a vertical axis to form symmetrical grips, eliminating separate tooling for left and right hands.

A mechanical load indicator uses a spring and spinning member to signal when horizontal lifelines reach required tension levels.

Preliminary action installs the L-shaped body and clamp before door opening, eliminating unprotected time windows for personnel.

A belt tensioner divides tensioning force into partial forces to charge a piston and traction element concurrently.

Flexible polyurethane foam forms a pet seat cavity that routes vehicle seat belts, preventing chewing damage while maintaining secure attachment.

A strap with a thickness gradient transition region manages energy absorption through controlled tearing.

A seatbelt pretensioner uses porous intermediates and vent holes to safely dissipate residual gas pressure, preventing injury during disassembly.

A locking jaw assembly uses inserting bolts to constrain a controlling member against ratchet teeth on a support rod.

Segmented pawls engage a protrusion to stop rope seat rotation, eliminating guide pin breakage and spring slip risks.

Dividing the monolithic anchor head into two side rods simplifies manufacturing and reduces assembly time compared to complex through-hole processing.

A seatbelt pretensioner cylinder uses a movable piston to tension the restraint webbing directly.

A safety device uses two brake assemblies to arrest falls or control descent speeds.

Segmented web harness belt combines ventilation mesh with ballistic protection to resolve the trade-off between user cooling and structural complexity.

Elbow linkage extends the anchor spike into roofing material, resolving weak anchoring reliability without adding device complexity.

Segmented fixing rod segments prevent restoring spring disengagement, ensuring reliable safety locking during fall events.

An adjustable webbing belt accommodates varying user sizes to replace multiple specialized systems, reducing device complexity.

Segmented bodies with a hinged second part align with cable tension, preventing structural damage during high-stress events.

A pivotable gate enables mid-rope access to bollards, solving attachment difficulties at height and eliminating the need to thread ropes from the free end.

A transparent reservoir and LED indicator provide visual substance level monitoring and spray path illumination.

A tubular fall indicator acts as a force-transmitting component between the pulling and anchoring elements of a preloading assembly.

Folding a flat webbing strap into nested layers creates a seamless tubular loop that eliminates hard edges and reduces abrasion on tie-in points.

Garments with integrated torso and leg strap systems enable rapid extraction of individuals during rescue operations.

A movable safety mechanism in a junction box enables users to switch between aerial tracks without unhooking.

A safety line traveller uses a reconfigurable braking mechanism to enable sliding movement along the line.

A controlled descent safety harness uses a rack and Kevlar webbing to prevent rope tangling during fall arrest.

A belay device uses a movable karabiner along a curved guide path to transition between unlocking and blocking positions for rope control.

A flexible drive member rotates a spool more than 360 degrees to retract the seat belt during a crash event.

A vehicle restraint system uses a movable member and retractors to secure occupants during travel.

A mobile eave hook device with wheels and an arched member anchors to roof edges.

L-shaped guide rail moves buckle to lumbar position, suppressing submarine phenomenon without seat modification.
