What the claims cover, in plain language

Claim 1 - a baby carrier with a snap button system (male on shoulder strap, female on drum bag) and an integrated structure for the shoulder strap and bulge.

Claim 3 - specifies a waist belt with webbing and buckle, and a detachable waist pad with two loops for threading the webbing.

Claim 4 - the inner side of the waist pad has three arc-shaped air guide grooves.

Claim 5 - introduces detachable connecting belts in an “X” shape, linking the drum bag’s first ear piece and the waist pad’s second ear piece via spring ladder buckles.

Claim 6 - a top flap sewn on the outer side of the waist pad covers the second ear pieces.

Claim 7 - side pads consisting of first and second gaskets sandwich the lower part of the shoulder strap.

Claim 8 - details the slide rail mechanism with a slide rail cover and a line position to limit the sliding distance of the slide buckle, enabling width adjustment.

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 has lapsed, so it no longer restricts anyone in China either. It has no US or other foreign counterpart.

Two points to settle early:

  • Other patents may exist. The baby carrier market is highly competitive with numerous active patents regarding ergonomic seating, buckle mechanisms, and load-distribution structures held by major brands like Ergobaby, Tula, and Babiators. A freedom-to-operate (FTO) review is essential before tooling to ensure the specific slide-rail width adjustment and X-strap configuration do not infringe existing US IP.
  • Safety Standards Compliance. US regulations for infant carriers are strict. The design must meet ASTM F223 requirements for structural integrity and labeling, which may influence material choices and testing protocols beyond the patent description.

Customization and manufacturing

What can be customized

AreaOptions
FabricCotton, polyester blends, mesh panels for breathability
Padding MaterialEVA foam, memory foam, or high-density polyurethane for drum bag/waist pad
Buckle TypePlastic quick-release vs. metal hardware for connecting belts
Rail MechanismInjection-molded plastic slide rails vs. metal track systems
ColorwaysPantone-matched dyeing for webbing and fabric
Logo PlacementEmbroidery or woven labels on the top flap or shoulder straps

Things to plan for (US market)

  • ASTM F223 - Standard Consumer Safety Specification for Soft Infant and Toddler Carriers. Mandatory for sale in the US. Covers flammability, structural integrity, and small parts.
  • CPSC Guidelines - General safety rules for children’s products, including tracking labels.
  • California Prop 65 - If using certain plastics or dyes, screening for chemicals known to cause cancer or reproductive harm is required.
  • Flammability Testing - Fabrics used in carriers must pass specific burn rate tests per ASTM standards.

How a project runs

  1. Inquiry - Define target age range, weight capacity, and aesthetic preferences.
  2. Design - CAD modeling of the slide rail mechanism and pattern grading for the drum bag.
  3. Prototype - Sew samples with functional slide rails and test X-strap tension.
  4. Pilot run - Small batch production for safety testing (drop tests, pull tests).
  5. Production - Bulk cutting, sewing, injection molding of buckles/rails, and final QC.

Quantities & timeline

Injection molds for the slide rail covers and spring buckles require precision tooling. Fabric sourcing and color matching typically take 2-3 weeks. Safety certification testing adds 4-6 weeks.
