Inverts the fixing bracket position to lower frame height while integrating the belt anchor to reduce component count.

A seat belt webbing guide adjusts vertically via a spring-biased latch plate and release member to fit occupant torso positions.

An oblique support section extends longitudinally from vertical supports to reduce material volume while maintaining mechanical stability under load.

L-shaped bracket design distributes load across multiple plates to enhance structural integrity during vehicle collisions.

A vehicle seat frame connecting mechanism uses plug elements and recesses for rear-engagement attachment to a floor rail.

Relocating the pivot axis to the backrest upper area creates a force tripod that distributes loads via vectors, reducing frame weight while maintaining safety.

A U-shaped motorcaravan seat uses a braced frame to distribute forces across multiple anchorage points for secure passenger restraint.

A vehicle seat back frame anchors a fold-down spring to a tilting member for smooth reclining motion.

A seat depth adjuster uses a vertical locking unit with an unlocking lever to move a carrier plate along guide tracks.

Electrically connecting the metal seat frame to the vehicle chassis creates a Faraday cage that contains electromagnetic radiation from onboard electronics.

Bend a metallic sheet to form a U-shaped main body with an undercut flange using opposite press directions, eliminating the angle modification process.

A vehicle seat fitting uses radial centering cams to align the fastening ring with the driver for precise assembly.

Cushion structure dissipates crash energy via shell displacement, reducing injury risk while maintaining secure ISOFIX attachment.

A plastic webbing guide shell reinforced with a metal member resists twisting and damage when the belt is positioned outside the guide.

A vehicle seat lever uses a protrusion sliding on a shield projecting portion to restrain distal-end wobbling during rotation.

Segmented mounting plates isolate leg support functions from seat adjustment mechanisms, preventing interference with reclining or longitudinal movements.

A support guide device connects side and center cushion frames to distribute passenger weight across the vehicle body.

Second extension portions overlap side walls to suppress inward bending while avoiding interference with surrounding members.

A deformable bracket system absorbs rear impact energy through controlled elastic and plastic deformation of the head restraint support structure.

An oblique mounting surface on a rotating seat link moves a belt fixture to maintain constant tension during height adjustments.

A vehicle seat attachment element uses a sleeve and hollow cylinder to secure mounting across multiple axes.

A spline shaft-like molded form-fitting unit inserts into a seat component receiver to create a secure rotational mold closure for backrest angle adjustment.

A vehicle seat frame structure uses a shaft-hub connection with angular clearance to uncouple the spring device from the backrest frame part.

A vehicle seat bottom plate structure uses obliquely arranged reinforcing sections to distribute load and enhance rigidity.

Segmented plastic seat pan profiles reduce material usage while maintaining crash safety by aligning with the vehicle frame cross members.

Melt-solidification of a protruding iron portion within an aluminum thin plate hole reduces intermetallic compounds while maintaining joint strength.

Slit bolster segments incline outward under hip pressure to expand seating surface area, accommodating large hips without increasing vehicle seat volume.

A motor vehicle seat backrest uses a loop and hook fastening system to secure the structure.

A seat unit with a recessed pedestal and slide guides moves secondary components laterally for flexible passenger configurations.

Outer peripheral beads on a seat back frame panel member enhance rigidity, resolving insufficient strength at the outer edge.

An integrated convex restriction part prevents seat belts from falling into gaps between adjacent seat backs, improving usability without adding complexity.

Five radial reinforcing portions connect to a tubular mounting portion on a vehicle seat holding member, preventing detachment during use.

Segmented support elements route forces directly to the floor, reducing weight while maintaining stability.

A vehicle seat locking unit employs a hollow-cylinder counter-contour nested within a bearing bolt to resolve shear stress weakness while simplifying assembly.

Asymmetrical seat cushion frame panels adjust support distances to maintain ride quality when offset objects reduce the supported area.
