Movable Seats TRIZ Cases

Sliding trays bridge passenger and cargo zones via rails, resolving access time trade-offs while maintaining structural stability.

Segmented locking elements prevent rear-end separation during crashes, reducing device complexity and manufacturing costs.

A wire harness routing device uses a slidable holding member to position the linear part along a rail.

Overlapping flange elements with nested rolling tracks provide structural stability for vehicle seats under high rotational loads.

A lock spring support structure with an uplift prevention projection holds the supported portion in place.

Coupled legs rotate to adjust an angle, displacing the support element vertically and longitudinally to reduce adjustment time.

A raising mechanism uses a driving member to pivot front and rear blocks for height adjustment.

Multiple wedge members lock inner and outer gear plates, preventing loosening during vehicle vibrations by distributing contact points.

An angled pin-guide surface forces the pivot pin into a retracted state during insertion, simplifying the attachment mechanism and reducing assembly complexity.

A rear vehicle seat integrates a pivotable storage hoop that extends outwardly to provide secure cargo support.

Hinged backrests and retractable pads enable multi-position seating while concealing mechanisms to maximize aft deck space.

An integrated mass element detects high acceleration to trigger a locking mechanism, preventing uncontrolled sliding during accidents.

A vehicle seat hinge mechanism uses a stepped-down recess in an annular rim to guide a stop member for angular position adjustment.

Longitudinally crowned worm gears localize contact to reduce noise and vibration while improving component robustness.

Integral stamped pawls with matching planar surfaces replace forged components to eliminate time-consuming manufacturing steps.

A vehicle seat controller moves a front seat assembly to an accommodation position using integrated sensors and actuators.

An asymmetric tooth profile prevents tip-to-tip non-locking conditions in vehicle seat mechanisms, eliminating complex tolerancing requirements.

A seat cushion tilting apparatus adjusts the cushion angle independently of the seat back position to enable desired relaxation postures.

A mobile device queries a database of physical characteristics to retrieve matching seat settings, eliminating trial-and-error adjustments.

Segmented walls dissipate impact forces to maintain structural integrity without requiring expensive high-strength materials.

An embedded track and swivel adapter resolve accessibility contradictions by allowing lateral repositioning and rotation of a child seat within a vehicle.

Clipped manual lever assembly eliminates translational stops to reduce seat track complexity and unit cost.

A deceleration-triggered pawl engages a toothed segment to lock the seat linkage before belt loads build, preventing occupant movement.

Elastomeric buffers absorb shocks to improve comfort without increasing weight, resolving the contradiction between portable handling and user back pain.

A vehicle seat anchor bracket uses segmented brackets to resist collision loads while minimizing weight.

A disc recliner assembly uses a lost motion bushing connection to gang two mechanisms together for simultaneous seat back adjustment.

Motorized pinion pivots seatback frame via gear system for controlled movement between upright and folded positions.

Bent wire springs stabilize lock plates in sliding devices, preventing force deviations that cause operational instability.

A sliding device incorporates a load receiving portion to inhibit movable rail deformation under compressed loads.

An asymmetric locking design applies standard engagement on one side and load-responsive deformation on the other to resolve weight versus strength trade-offs.

A vehicle seat fitting system uses a prestressed latch on one side to secure the backrest pivot axis without additional actuation forces.

A normally open relay in the seat motor circuit blocks power during collisions to prevent unintended actuation while allowing rescue access.

Two rotatable adapter elements secure electric drive units to vehicle seat frames, resolving fixed positioning limits.

A seat angle regulator uses a friction-based resistance torque structure to transmit drive cam motion directly to an eccentric wheel.

Interlocking clamping elements direct crash forces into a reinforcing profile, preventing overstress on the rail pair.

A cylindrical bearing bush with a blocking section engages a body-side backrest bearing to pivot and lock the vehicle rear seat structure.

A seat deformation element uses a sectionally reshaped weakened area to tear open under impact forces.

A seat adjustment mechanism uses a pull-wire system to transmit user force for secure locking.
