Seat Suspension Devices TRIZ Cases

Air spring pressure automatically adjusts seat damper hardness to match driver weight and road vibration, improving comfort and end-stop protection.

Sensor-based damping control switches modes from normal to maximum damping when seat motion exceeds thresholds, reducing vibration and bottoming out.

Occupant condition data corrects active suspension attitude control to reduce resonance-frequency vibration and improve support during vehicle motion.

Prefiltered road data lets the seat suspension anticipate high-frequency inputs while avoiding phase-delay issues on low-frequency hills and curves.

Occupancy sensing switches a suspended vehicle seat into a protective mode that locks position and raises damping to prevent suspension damage.

A center-balanced rotary actuator moves the seat linkage linearly to cut twist, wear, and acceleration transmission in compact suspensions.

A crash-triggered piston drives the scissor seat downward in rollovers, preserving head clearance from the cab crossbeam.

A decoupled air spring, damper, and self-levelling valve keep seat height adjustment separate from preload for consistent vibration damping.

Pressure sensors and a trained model auto-adjust the seat, backrest, and headrest to fit body shape and reduce manual setup time.

A piston-driven stop member lowers a raised scissor seat during rollover to prevent head contact with the cab crossbeam.

Rolling rails, shock absorbers, and springs isolate lateral seat motion to reduce driver vibration and discomfort on rough roads.

A mechanical assembly converts vertical motion into horizontal damping, separating spring and damper action to cut friction and residual vibration.

A lateral spring and linkage layout cuts forklift seat installation space while keeping stable suspension and adapting support to different user masses.

A motor-driven gear belt repositions the scissor arm rolling axle to damp seat vibration without damper end stops or overshoot.

Grooved seat support and padding create an internal airflow volume that cuts mounting parts, reduces weight, and improves ventilation.

A rigid-foam spring element and linked retaining arms guide seat scissor motion with less friction, lower maintenance, and consistent damping.

An integrated scissor-arm suspension cushions seat roll and vertical motion while reducing complexity and enabling adjustable spring stiffness.

Differential link angles, spring mechanisms, and dampers improve front-rear and vertical seat vibration and impact absorption.

Real-time sensor control and low-friction damping reduce seat suspension sticking, vibration, and energy transfer to the occupant.

Vehicle body vibration sensing lets active suspension react before seat motion occurs, improving damping response, stability, and sensor count.

Automatic torsion-angle sensing and elastic force adjustment keep the seat suspension at its balanced point to improve vibration and impact absorption.

A scissor seat suspension uses paired fluid springs and fluid transfer to absorb roll and vertical motion while keeping the seat nearly horizontal.

A variable working volume adjusts air spring pressure to keep seat height stable while avoiding slow, noisy compressor-based regulation.

A seat design sets the seating-member to frame-displacement ratio at 20 or more to preserve damping, reduce body-seat motion, and improve ride comfort.

A two-stage seat suspension uses an intermediate frame and direct base-to-seat damper path to absorb vibration and impact with less structural complexity.

Differentiated link angles isolate front-rear seat motion, improving vibration and impact absorption on uneven vehicle terrain.

A linearly displacing lock member fixes the suspension seat within its vertical travel, simplifying the mechanism and stabilizing occupant support.

Vertical motion is converted into horizontal damping to cut friction, reduce residual acceleration, and save suspension space.

A pivoted linkage gives a vehicle seat suspension damper higher damping away from neutral and lighter return damping to cut bounce and improve comfort.

Two cooperative non-back-drivable actuators control seat roll and heave in compact vehicle spaces while cutting power use and bulk.

A motion-sensor-controlled seat damper adapts in real time to road vibration and occupant weight, reducing oscillation and manual adjustment.

A chassis-mounted retaining member locks the suspended seat platform during impact to prevent forward shift, pivoting, and pelvis injury.

A vehicle seat vertical suspension check belt system routes a belt band around a lower axle to transfer forces between guide frames.

A vehicle seat height adjustment device integrates a pneumatic damping element with a counteracting spring to manage vertical movement.

A stratified seat structure uses layered viscoelastic materials to absorb excitation frequencies and dissipate mechanical energy through internal friction.

Nested spiral springs inside a tubular frame reduce construction complexity and space requirements while maintaining high suspension comfort.

Disk spring stacks in a quasi-zero-stiffness isolator absorb lateral vibrations from the seat base, preventing amplification at the seat back.

A vehicle seat suspension adjusts spring unit position via an adjusting device to change extension force.
