Seat Frames TRIZ Cases

Segmenting the cushion frame allows independent rotation of front and rear portions, suppressing leg raising and back shifting during recline.

A vehicle seat back frame uses a transmission rod to channel width-direction loads into a resin spacer.

Pre-formed grooves on the seat frame accept protrusions from side members, securing rigidity while preventing separation under external impacts.

A damped pivot mechanism controls seat bottom rotation to prevent occupant submarining during frontal impacts.

Integrated mounting bracket secures flexible hoses to seat frames, preventing kinking that compromises weight sensor accuracy.

Segmented safety assembly uses flexible connecting member and fixed floor anchor to distribute impact forces without occupying trunk volume.

Segmented tilt restriction mechanism with offset abutting member reduces occupied area while maintaining back frame angle.

A vehicle seat striker uses a threaded shaft to fasten the seatback frame through upholstery.

Front and rear hooks anchor S-shaped springs to the frame, eliminating complex engagement mechanisms that increase manufacturing costs.

A vehicle seat fitting system uses a spring steel quick fastener to secure the drive shaft and driver axially.

Segmented belt frame and modular restraint system enable functional upgrades without redesigning the permanent vehicle structure.

An injection molded thermoplastic seat backrest embeds elongated reinforcements to reduce weight while maintaining structural integrity.

Laser welding attaches the encapsulating ring to the housing plate, preventing heat-related distortions and improving torque strength.

A structural material integrates thin steel members with reinforced portions to balance strength and toughness profiles.

A conveyance seat unit adjusts its neck load portion based on occupant body shape and sex to reduce impact forces.

A tiltable belt guide surface prevents seatbelt slippage while a regulation member stops excessive inclination to avoid pressing the lock release switch.

Segmented attachment points distribute crash loads across multiple resilient regions, resolving stability issues in single-plane floor mounts.

An integrated connecting member merges the headrest frame and bracket into a single structural unit.

A passenger seat uses a floating bearing to allow smooth movement along guide rails.

Optimized boron-steel composition achieves 1170 MPa yield strength, resolving the trade-off between weight reduction and weldability in seat structures.

Integrating seat anchors with the rear bulkhead reduces installation time by eliminating separate mounting operations on the floor panel.

Segmented lever brackets distribute forces across multiple fixing points while an intermediary cable guide prevents entanglement in the panel frame structure.

A vehicle seat bearing structure uses folded side edges to form a U-shaped profile that increases mechanical strength without adding material thickness.

Segmented deformation brackets manage impact forces by translating the head restraint toward the seatback, reducing whiplash risk.

A foamless seating assembly uses a tension assembly to apply simultaneous force to flexible straps on inner and outer support members.
