Seat Frames TRIZ Cases

A seat bottom cross beam positioned on support block flanges provides lateral structural reinforcement without penetrating the cushion layer.

In situ injection molding bonds fiber layers to a pre-molded part using low viscosity reactive matrix impregnation, eliminating separate GMT stacking steps.

Offset coupling member distributes load energy through bracket deformation, reducing stress concentration at the joining area.

A laser welding method uses austenitic filler material to join TWIP steel and low carbon steel.

A vehicle seat back side portion uses a rotation-restricting portion to prevent wobbling and enhance rigidity.

Chamfered transverse tube bearing surfaces clamp connecting parts to prevent axial movement and ensure secure rotation fixation.

Arching side walls with variable height provide a secure structure for upholstery lining installation on mass transit vehicle chairs.

Multi-bar link mechanism lifts the front end and lowers the rear end to achieve a neutral thigh angle, reducing driver fatigue during long drives.

Accelerometer-driven air bladders inflate seat bolsters to maintain occupant position during cornering.

A pivot bracket raises the seat cushion edge to eliminate vertical gaps during recline.

A vehicle seat back frame connects side frames via upper and lower members with a connecting pipe, mounting the seat belt retractor on a dedicated bracket.

Inverting fixing portions inwardly within the operation knob axis reduces side frame area while maintaining structural rigidity and operational stability.

Sacrificial energy absorption disc absorbs impact energy through controlled fracture, reducing head rebound speed and improving passenger safety.

A bush absorbs welding heat between gear plate and bearing to prevent thermal damage, while a welded retainer increases coupling force.

Plate-shaped cushion panel features ischial region through holes for occupant pressure relief.

A conveyance seat frame incorporates a resonance suppressing portion formed by continuously arranged non-penetrating recesses and protrusions.

A modular vehicle seating insert uses a universal shell structure with standardized connection features to support interchangeable seat modules.

A chamfered bolt and floating bushing system centers attachment means for secure vehicle seat base clamping.

Synchronized inward punch dies swage projecting housing edges through aligning slots, resolving misalignment and weak attachment in foldable headrest assembly.

Elastic deformation adjusts bearing clearance before plastic stamping eliminates tolerance sorting costs.

Segmented side frames with fragile portions absorb rear collision energy while maintaining normal rigidity and controlling backward inclination.

A compressible member interposed between chassis and seat attachment portions absorbs impact forces during vehicle operation.

A vehicle seat uses a mobile beam and cam mechanism to lock components securely.

A manual recline swivel mechanism uses a single locking key to engage spindle gears and gear plates for shell assembly adjustment.

A vehicle seat recliner second flange uses a single circular outer surface to join the frame.

An integrated seat shell merges tilt and cushion adjustments into a unified structure, canceling engagement via a flip-up operation to reduce part count.

A vehicle seat speaker assembly directs audio toward passengers using a support frame with side projections, minimizing disruption to other occupants.

A vehicle head restraint assembly uses a stationary hub and integral bearing surfaces to pivot the core portion.
