Weight and Height Parameters for Stature-Based Newborn Fit
Under ECE R129 standards, child safety seats classify occupant ISOFIX infant car seat primarily by standing stature rather than approximate weight brackets alone.
For the MY-566 newborn car seat, engineering begins at 40 cm to protect neonates and extends up to 87 cm, securing reliable spinal alignment through early infant growth stages.
Approved stature range ensuring proper harness slot heights from hospital discharge through 87 cm.
Optimized shell weight for practical carrying and vehicle handling without sacrificing structural rigidity.
Anatomical Fit for First-Stage Protection
- Supports infants starting at 40 cm with dedicated newborn wedge and body cushions.
- Dedicated rear-facing geometry cradles cervical spines and reduces head deflection.
- Precision shoulder-belt routing prevents strap slippage on narrow neonatal shoulders.
MY-566 Stature Sizing Specifications
OEM distributors and brand partners can verify the technical dimensional criteria for global regulatory compliance.
| Parameter | Technical Standard | Engineering Objective |
|---|---|---|
| Stature Range | 40 cm to 87 cm (ECE R129) | Provides snug torso fit and correct harness strap height at every growth phase |
| Seat Orientation | Strictly rear-facing configuration | Distributes frontal crash loads uniformly along the entire back and neck shell |

Dedicated Rear-Facing Architecture for Newborn Spinal Protection
Engineered strictly for rear-facing transit from 40 to 87 cm, the MY-566 shell channels frontal collision energy across the entire backrest to safeguard cervical vertebrae before infants transition into stage-based convertible all-in-one car seats.
Full-Cradle Energy Dissipation Shell
Reinforced polypropylene shell structure absorbs crash deceleration forces, evenly supporting the newborn head, neck, and dorsal spine.
Ergonomic Newborn Incline Alignment
Internal contours help maintain an open airway (per manual geometry) and prevent chin-to-chest flexion during travel without compromising impact restraint.
Deep Side-Wing Lateral Shielding
Integrated energy-absorbing side wings isolate the infant head from intrusion vectors during side-impact collision events.
Dedicated rear-facing support from birth up to 87 cm.
Lightweight structural build for agile logistics and handling.
Validated under ECE R129 dynamic criteria including side-impact.
Dedicated rear-facing geometry for the newborn stature window.
