A sliding track, pivot bracket, roller, and spring supports let a rear seat switch orientation and move onto the open tailgate for compact storage.

Inward flange portions relocate cushion spring attachment, freeing side-wall space, simplifying the frame, and reducing seat pad deformation.

Adjusting the upper suspension wire changes the back rest swing center to match shoulder blade height, improving posture stability and reducing wear.

By removing the cushion side frame and integrating links and brackets, this seat structure cuts weight while preserving support and seatback connection.

A lever-driven latch and rotation shaft let the seat frame fold toward the seat back, saving space while reducing part count and maintenance.

A three-link seat pitching mechanism replaces a four-bar layout to cut parts while improving rigidity, impact resistance, and walk-in operability.

A tub-shaped seat support with flexible sides and a tensioned surface cuts weight and parts while improving durability and cleanability.

Routing the backrest tilt axis through the seat connecting tube cuts installation space and preserves forefoot room behind the seat.

A seat-driven linkage raises the vehicle load floor to remove the step at folded seat backs and make cargo sliding easier.

Overmolded plastic film strips replace metal seat-back suspension sheets to cut weight, simplify assembly, reduce noise, and support airbag guidance.

Independent support links let a vehicle seat rotate into facing or relaxed postures with fewer parts, lower weight, and less cabin interference.

Pivoting seatback panels add seating space and form a flat load floor, while biasing members and limiters reduce noise and vibration.

A coaxial fixing element joins the spindle and worm gear to improve crash-load capacity and torque transfer in vehicle seat adjusters.

A variable-thickness tubular seat back preserves strength while reducing weight and freeing more passenger living space.

Recessed cross-member geometry cuts seat frame weight while preserving stiffness and improving occupant comfort through smarter material placement.

A pivoting backrest and retaining mechanism let one vehicle seat frame switch between single-seat and bench configurations with stable support.

Separating the load sensor from the front link shaft in the seat fore-aft direction preserves height adjustment while keeping the seat compact.

A reinforced fixing member on the seat cushion back uses spaced attachment points and through holes to secure luggage more reliably.

A hook, cable, and strap latch lets a vehicle seat fold from various positions while reducing part count, weight, and maintenance.

A linked front-foot closed section boosts seat support stiffness while cutting parts, weight, and packaging space in vehicle assembly.

Open-section seat back frames overlap and laser weld to raise rigidity and joint strength while limiting weight, deflection, and noise.

Shape memory members tilt the seat cushion against cornering forces, adding lateral support only during high acceleration to preserve normal driving comfort.

A floating support surface uses frictional energy conversion to extend stopping distance and reduce crash forces on passengers or cargo.

A compact nested seat mechanism pivots, extends, lowers, and tilts the OEM seat to ease wheelchair transfer without replacing safety-critical seating.

By removing the cushion side frame and using rails, links, and brackets, this seat structure cuts weight while preserving height and angle adjustment.

Reduced outer diameter contact surfaces enable secure welding between equal diameter pipes and collars, boosting torsional strength without adding weight.

A seat mounting member with a deformable core absorbs directional forces through controlled structural deformation.

Synchronization bar merges force transfer and crash absorption to reduce manufacturing costs while preventing occupant submarining.

Upward-extending appendages anchor waist belts between seats, resolving frame absence constraints for off-road vehicle occupant restraint.
