What the claims cover, in plain language
Claim 1 defines a seat cushion comprising a cushion cover, clamping shell, clamping plate, and rubber pad. The cover has elastic bands connecting to the clamping shell. Inside the shell, a sliding column carries a pull head and a limiting toothed plate, biased by a spring. A storage groove receives the toothed plate when pulled. The clamping plate, attached to the elastic band, has tooth grooves that mesh with the toothed plate to lock the position. The claim further specifies a leaning bag with a unidirectional air inlet valve, telescopic air pipe, and pedal balloon for inflation, along with breathable nets and magnetic therapy blocks.
Claim 2 specifies the cushion core is hydrophilic sponge. Claim 3 states the elastic bands and cover are connected by sewing, and the cover is cotton cloth. Claim 4 details the connection between the sliding column, spring, and pull head. Claims 5-10 refine the meshing of the toothed plate, the dimensions of the slots relative to the plates, and the material of the breathable nets (nylon).
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for US production
This patent was filed only in China and is currently active in that jurisdiction. It has no US or other foreign counterpart. Making or selling this specific configuration in China requires the owner’s permission. For US production, the patent itself does not restrict sales in the United States, but the underlying technology must be checked against existing US patents.
Two points to settle early:
- Other patents may exist. Ergonomic seat accessories and locking mechanisms are heavily patented fields in the US. While this specific combination (toothed slider + inflatable bag) appears novel in this filing, similar ratchet-based strap adjusters or integrated lumbar bladders may be covered by prior US utility patents. A freedom-to-operate (FTO) review focusing on mechanical strap adjusters and integrated pneumatic lumbar systems is recommended before tooling.
- Material Compliance. The use of hydrophilic sponge and specific fabrics requires verification against US flammability standards for upholstered furniture, which differ from general textile rules.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Cushion Shape | Square, rectangular, or contoured profiles to match specific chair types. |
| Cover Fabric | Cotton (as patented), polyester blends, or moisture-wicking technical fabrics. |
| Core Material | Density and thickness of the hydrophilic sponge; memory foam alternatives. |
| Locking Mechanism | Tooth pitch and count for finer adjustment steps; plastic vs. metal sliding columns. |
| Lumbar Bag | Size and shape of the inflatable bladder; manual vs. electric pump integration. |
| Colorways | Full range of Pantone-matched colors for cover, bands, and plastic components. |
Things to plan for (US market)
- CPSC 16 CFR 1640 / ASTM F1449 - Flammability standards for upholstered furniture. Foam cores and fabric covers must pass smolder and open flame tests.
- Proposition 65 (California) - Requires warnings if certain chemicals (often found in plastics, foams, or dyes) exceed safe harbor levels.
- REACH (if exporting to EU) - While not US-specific, global supply chains often require REACH compliance for chemical substances in plastics and textiles.
- UL Standards (for electric pumps) - If the pedal pump is replaced with an electric motor, UL certification for electrical safety is required.
How a project runs
- Inquiry - Define cushion dimensions, fabric preferences, and quantity.
- Design - Create CAD models for the clamping shells, sliding columns, and mold cavities for the sponge.
- Prototype - 3D print mechanical parts; hand-sew initial fabric samples to test fit and locking action.
- Pilot Run - Injection molding for shells, cutting and sewing for covers, assembly of inflatable bags.
- Production - Mass manufacturing of components, final assembly, packaging, and quality control checks.
Quantities & timeline
The clamping shells and sliding columns require precision injection molds. The sponge core needs die-cutting tools or CNC foam cutters. The inflatable bag requires heat-sealing dies. Lead times depend on mold complexity and fabric sourcing. Send us your target dimensions, fabric choices, estimated order volume, and delivery schedule and we will reply with options.
