Back Rests TRIZ Cases

Inward contact zone engages vehicle body to reduce flexing and improve comfort in prisoner transport seats.

Rotatable rail portions absorb path deviations to eliminate rattling noise from fixed striker connections.

Link brackets and rotary screws move an elastic support panel to resolve stability and deformation issues in vehicle seats.

Direct contact injection eliminates border separation members, reducing thickness and cost while maintaining hardness differences.

Bracket-mounted bolt fasteners prevent resin creep deformation by distributing clamping force across a larger contact area.

Inclined upper cross member connects to side brackets, resolving frame compatibility issues across different vehicle types.

A quick-release mechanism decouples strap tension from installation, allowing fast backrest removal without manual adjustment.

Curvilinear backrest pad with integrated gripping structure engages operator hips and back for stability.

An elastic connection member allows lumbar vertebrae to sink into the upper opening, reducing concaved terrain discomfort while maintaining headrest protection.

A vehicle seat side support structure uses a recessed rear face material to disperse body pressure.

Detachable backrest element relocates to the seat pan, creating a continuous bed-like surface while minimizing structural weight and space requirements.

Flat surfaces on a clip and rod mechanically engage to maintain headrest position, eliminating reliance on biasing elements for positional stability.

Deployable airbag assembly inflates within the seat thigh support region to adjust the support surface angle.

Elastic tensioning member biases seat belt cover extension to adjust positioning within vehicle seat assembly for varying passenger sizes.

A seat adjustment device moves a vehicle seat from a comfort position to an upright position using transition signals during automated driving mode switchover.

A vehicle seat cushion uses a flat spring with movable clamp rollers to adjust its swing range and restoration force.

A deformable cell with a contraction zone absorbs impact energy between the seat frame and trim cover.

A vehicle seat backrest adjusts width via an elongated crossbar connecting longitudinal supports.

An impact pad with expandable polypropylene foam absorbs collision energy while maintaining structural support and occupant comfort.

Integrating a thermoplastic matrix with fiber reinforcement achieves high stiffness and impact strength while maintaining lightweight design and recyclability.

Non-expandable surface structures introduce tensile loads to overcome cover resilience, reducing side airbag reaction time.

Composite polypropylene and modified olefin elastomer foam eliminates metal frames to reduce weight while maintaining impact resistance.

A vehicle seat backrest uses a lateral displacement device to move the upper section out of view.

An inverted U-shaped bridge positions motors vertically above lumbar bands, reducing volume in vehicle seating while enabling four-way adjustability.

Guide pins slide along slots while lumbar unit rotates rearward, projecting the headrest forward to prevent neck injury without compromising riding comfort.

Asymmetric backrest recesses provide targeted arm and elbow support, resolving the trade-off between rear visibility and driver comfort.

A pyrotechnic actuator pulls an inflatable airbag via a tether to position the safety component over a vehicle occupant.
