Vehicle Seats TRIZ Cases

A recessed seat container, tube, and funnel let users urinate while seated in vehicles, improving privacy, safety, and waste containment.

A cam wedge and pivot rod package lets a vehicle headrest dump smoothly with push-button or cable actuation while reducing mechanism complexity.

A single fluid-filled bladder pivots headrest side parts through lever arms, simplifying lateral support adjustment and protecting the mechanism.

A lateral translation linkage lets a reclining cabin seat stow partly in a housing, saving space while preserving comfort and egress.

A ledged head indentation and neck cradle stabilize the head, resist twisting moments, and improve lateral support during long trips.

A seat unlocking unit keeps a visible indicator active until all locking devices are secured, simplifying multi-lock status checks.

An annular headrest and chest support adjust in height and angle to ease forward-leaning rest, breathing, and neck-back strain.

Microcoils pocketed in a quilted sleep layer move spring support closer to the sleeper, improving pressure relief, airflow, and mattress life.

Sliding and hinged side wings widen head support in economy aircraft seats while staying compact enough for standard seat-back dimensions.

Gentle pressure at selected body contact points promotes upright posture and mobility without straps or bracing that trigger resistance.

A torsion-spring headrest pivots upright in use and retracts when lowered, improving rear visibility while avoiding torso contact discomfort.

Wire loops and a retainer mount the headrest to the seat panel so it moves with occupant shifts and avoids mesh panel damage.

Flush rear and side seatback doors combine rigid panels with flexible fabric sidewalls to add storage space without bulky external compartments.

Closed-surface seat channels maintain airflow without through-openings, reducing dirt entry and making chair shells easier to clean.

A movable bent conductor in a seat pad groove cuts friction and bending stress, preventing load sensor wire disconnection under seating loads.

Separate pneumatic cushion chambers let aircraft passengers vary seat firmness, support, and leg position beyond fixed foam seating.

Independently controlled air cells vary pressure and stiffness to reduce seat hot spots, uneven loading, and vibration on long flights.

A four-link leg rest mechanism replaces complex six-axis motion to cut parts and weight while improving downward support and operating force.

Extendible chin-support pads on child seat headrest side wings help keep a sleeping child's head upright while allowing size adjustment.

Titanium- and copper-alloyed steel coil springs improve stress distribution and durability in mattress cores without added bulk.

Slits in the case side walls let longer shaft portions insert with less resistance, improving vehicle baggage hook load bearing.

A low-profile clip uses resilient engagement and transverse release elements to secure cushions while allowing fast removal in harsh marine conditions.

Dual synchronized cams and latches let a vehicle head restraint fold for rear visibility while sustaining higher impact loads with less noise.

A hollow-loop thermoplastic network cuts compression noise while keeping cushioning and low weight through controlled hollowness, fiber size, and weld density.

A seat-integrated toilet uses a concealed waste bag and locking seat structure to provide private, hygienic vehicle use without plumbing.

A single-piece U-shaped rod combines headrest retention and actuation to cut parts, lower assembly cost, and improve impact resistance.

A pivoting headrest nests inside the seat back while a flexible panel covers the cavity, preserving comfort, appearance, and easy deployment.

A gear-driven rotary shaft and elastic member cut motor power, weight, and noise in a seatback footrest while improving rear passenger comfort.

Embedded tubular foam springs with reinforcement ribs balance impact support and ride comfort while reducing seat cushion cost and complexity.

Segmented pads with adhesive strips and absorbent polymer fit varied seats, contain spills, and keep car seat strap openings clear.

Electrostatic discharge fibers in seat suspension detect occupancy and posture from electrical changes without adding bulky sensing hardware.

A lifting airbag separates the seat cover from massage airbags, allowing smooth position adjustment under occupant load with a smaller actuator.

A shock-resistant headrest opening places a non-contact microphone inside to collect voice clearly while reducing head impact.

An oblique-face locking member removes upright headrest gaps, reduces wear-driven complexity, and simplifies seat assembly and cost.

A thermoplastic random-loop bonded structure cuts compression set while retaining hardness under repeated loading for cushioning uses.

Localized hardness zoning softens the seat surface and stiffens the base to reduce thigh pressure, limit buttock sinking, and improve fit.

Telescoping legs, rotatable anchors, and angle locks turn a compact travel pillow into stable head and neck support with adjustable height and privacy.

A sheet-like fastening member is sandwiched under a foot bracket to stop floor mat edge rise, avoid seat rail interference, and keep sliding smooth.

A movable restraint bar uses thigh-contact sensing to lock only on effective passenger contact, improving fit and retention across rider sizes.

An integrated hook, lip, and projection lock a tablet holder bezel in place without extra fasteners, improving attachment security and assembly speed.

A tapered sacral bladder with angled iliac bladders and sensor-based pressure adjustment helps maintain neutral pelvic posture and reduce hyper-flexion.

A two-section pawl spring lets a vehicle headrest lock at upright and inclined positions, then return to upright with a compact ratchet.

A base-and-cover mount clamps seatback struts to hold accessories securely while preserving headrest adjustability and fit flexibility.

Pre-boring pipe ends into thin-walled sections enables 5 mm+ R chamfers with less forming force, reducing cracks and meeting safety standards.

Curved guide rails move the seat frame forward and tilt it smoothly, improving rest-position comfort without extra actuators.

Elastic seat panels move independently to fit passenger shapes, improving load transfer while cutting aircraft seat weight.

A lateral lock pin and lock-hole layout replaces long shafts, cutting headrest adjuster weight, thickness, and part complexity.

A tensioned diaphragm over a contoured seat pan cuts contact pressure and beam contact, enabling thinner, lighter aircraft seat cushions.

Smaller perimeter spring pockets strengthen cushion edges and reduce foam use while the central spring matrix preserves contouring and support.
