On a 40-150 cm i-Size car seat, "40-150 cm" is the complete approved stature range. Read the internal modes separately. In the documented BW25 configuration, 40-105 cm is an integral restraint using the seat's harness, while 100-150 cm is a non-integral booster configuration in which the vehicle's adult three-point belt restrains the child. Orientation and installation hardware also change by mode, so the model label and manual matter more than the headline range alone.
An OEM child car seat fabric specification should identify the seat model, destination market, cover part map, visible fabric, backing or laminate, padding, binding, thread, attachment parts, logo method, labels, care instructions, color reference, test methods and pass criteria. Approve four physical stages: material swatch, sewn cover, fitted seat and packed production sample. A buyer should never release bulk production from a digital rendering or Pantone number alone.
A useful baby car seat factory audit follows one model from its UN R129 approval communication to the bill of materials, incoming components, molding, sewing, assembly, functional checks, Conformity of Production records and packed sample. Do not award the supplier because it shows a certificate, a clean showroom or a crash-test video. Approve it only when the legal entity, approved product identity, actual production site and current records connect without unexplained gaps.
Approve car seat artwork as one controlled set, not as separate label, manual and carton jobs. Start with the full approval identity and configuration matrix. Then check the on-seat markings, exterior packaging notices, complete user instructions, physical quick-start guide where applicable, translations, QR destination and a photographed production sample. A designer's PDF proves layout approval; it does not prove that the printed label is the right size, visible in use or attached to the approved seat revision.
UN R129 Conformity of Production, usually shortened to CoP, is the control system used to keep an approved child restraint in conformity with its approved type during production. A useful buyer review connects the approval identity to the controlled product revision, materials and components, production checks, markings and instructions, test records, change history and treatment of nonconforming product. A certificate, a factory inspection checklist or one test result cannot replace that chain.
Blow molding forms a hollow plastic part by closing a mold around a molten tube called a parison and inflating it with air. Injection molding pushes molten polymer through gates and runners into a closed mold cavity that defines the part. For a car seat project, choose the process after defining the part geometry, interfaces, material, required functions and approved configuration. Then inspect samples for process-specific risks. Never accept "blow molded" or "injection molded" as a standalone safety or quality claim.
