什么是

儿童安全座椅阶段试点帮助家长梳理从后向式安全座椅到前向式带安全带座椅、增高座椅以及成人安全带的 progression。它将孩子的生日或年龄与可选的体重和身高测量值结合起来，报告当前阶段、座椅类型、安全带指导、临近的座椅限制以及预计的下一次转换时间。这使 Openclaw Skills 能够用于回答诸如何时将座椅转为前向式，或孩子是否已经准备好使用增高座椅等常见问题。
该技能是信息指南，不能替代儿童座椅说明书、适用的州法律或实际安装建议。它明确不包括针对特定车辆的安装帮助，并在需要时引导用户联系认证的儿童乘客安全技术员。其指导参考 AAP、NHTSA 和 Safe Kids Worldwide；座椅说明书和当地法律优先。

应用场景

家长询问已满两岁的孩子是否可以转为前向式。
照护者想知道孩子的年龄和体型是否表明已经适合使用增高座椅。
家庭询问孩子何时可以停止使用增高座椅并改用成人安全带。
家长想将孩子的测量值与座椅的后向式或其他限制进行比较。
家庭正在为新生儿做准备，希望了解汽车安全座椅阶段的概况。
照护者根据年龄、体重和身高请求下一阶段的预计日期。
用户需要提醒，为处于增高座椅年龄的孩子应用五步安全带贴合检查清单。

工作原理

收集孩子的生日，或以月为单位的年龄，以及可获得的体重（磅）和身高（英寸）。在已知时询问当前座椅类型，包括是否支持延长后向式使用。
使用可获得的测量值运行随附的 Python 阶段脚本。添加 --json 以获得机器可读输出，或添加 --belt-fit 以请求五步安全带贴合检查清单。
阅读判断字段：POSITION NOW、SEAT NOW 和 HARNESS NOW。
查看所有 WARNING: 行。这些行表示某项测量值已达到或超过座椅限制，可能意味着到了转换时间。
将 NEXT TRANSITION 作为预测值使用，它基于由年龄、体重或身高驱动的最早日期。日期使用文档所述的粗略生长模型，是估计值而非保证值。
对于考虑使用增高座椅的孩子，应用五步安全带贴合测试；五项标准必须全部通过。遵循具体座椅说明书和当地法律。

配置指南

该技能会调用 scripts/car_seat_pilot.py 中的 Python 3 脚本。提供的 SKILL.md 未指定包管理器、单独的安装命令或额外依赖；在脚本可用时，从技能目录运行该脚本。
确认 Python 3 可用。
提供生日或年龄，并在可获得时提供体重和身高。使用脚本要求的测量单位：磅和英寸。
使用相应选项运行脚本：
python3 scripts/car_seat_pilot.py --birthday 2024-03-15 --weight-lb 24 --height-in 31
若要获得机器可读输出或安全带贴合检查清单，请添加文档中说明的标志：
python3 scripts/car_seat_pilot.py --birthday 2024-03-15 --weight-lb 24 --height-in 31 --json
python3 scripts/car_seat_pilot.py --birthday 2024-03-15 --weight-lb 24 --height-in 31 --belt-fit
使用有效的 YYYY-MM-DD 格式生日。将预计的转换日期视为估计值，并在采取行动前检查座椅自身的限制、说明书和州法律。如有安装问题，请联系认证检查站。

数据架构

该技能接受测量输入并报告阶段评估；提供的 SKILL.md 未说明持久化存储或运行时生成的文件。
输入或输出 描述
生日或年龄 优先使用生日；年龄（月）可作为替代输入。
体重 可选的儿童体重，单位为磅。
身高 可选的儿童身高，单位为英寸。
当前座椅类型 可选背景信息，例如典型座椅或延长后向式可转换座椅。
位置和座椅判断 当前建议的阶段位置和座椅类型，显示在判断区块中。
安全带指导 当前安全带规则，包括阶段特定的肩带位置和上固定带提醒。
警告 针对达到或超过座椅限制的测量值发出的通知。
下一阶段转换 根据年龄、体重或身高并使用文档所述生长模型估算的日期。
安全带贴合检查清单 面向增高座椅年龄儿童的可选五步评估。
参考分类包括 references/stage-rules.md（阶段规则、肩带位置、上固定带指导、法律差异、有效期和碰撞后指导）以及 references/growth-model.md（预测假设和误差范围）。使用 --json 调用脚本时，可以输出 JSON。

高级特性

--json 选项提供机器可读结果，适用于需要结构化输出的工作流。
可选的 --belt-fit 模式，用于提示五步安全带贴合检查清单。
限制警告会标记达到或超过座椅规定限制的测量值。
使用文档所述生长模型，结合年龄、体重和身高（包括其不确定性）预测下一阶段转换时间。
提供阶段特定指导，涵盖后向式、前向式带安全带、增高座椅和成人安全带阶段。
提供关于安全带肩带方向、前向式上固定带使用、座椅有效期以及碰撞后更换的安全背景；座椅说明书和当地法律优先。
明确的范围边界：该技能不提供针对特定车辆的安装说明，并建议有关问题咨询认证的儿童乘客安全技术员。

Car Seat Stage Pilot

Overview

Car-seat stages (rear-facing → forward-facing harness → booster → adult belt) are governed by THREE clocks at once: the child's age, weight, and height — plus the specific seat's limits. Parents get this wrong constantly: turning the seat at age 1 because "their legs look cramped", boosting a 3-year-old because "she's tall for her age", or dropping the booster at 6 because "the belt looks fine". Mis-staging is one of the most common — and most dangerous — usage errors found in car-seat check events.

This skill converts a birthday (or age in months) plus optional measurements into a definitive stage verdict: what position, what seat type, what harness rule applies right now, which limits are close, and when the next transition is projected.

When to Use

"My son just turned 2 — can I turn his seat around now?"
"She's 4 and 42 lb — is it booster time?"
"When can my kid stop using a booster?"
"The seat manual says RF to 40 lb — my toddler is 38 lb, how long do we have?"
"New baby arriving — what seat stage do we buy?"
Any request involving child age + car seat position/type/transition.

Don't use for: installation help for a specific vehicle (angle, tightness, anchor locations) — that's a certified Child Passenger Safety Technician job; direct the user to a local check station.

How It Works — Numbered Steps
Collect inputs: birthday (best) or age in months; weight in lb; height in inches; current seat type if known (typical vs extended-rear-facing convertible).
Run the stage engine: python3 scripts/car_seat_pilot.py --birthday 2024-03-15 --weight-lb 24 --height-in 31 Add --json for machine output, --belt-fit to force the 5-step belt-fit checklist.
Read the verdict block: POSITION NOW / SEAT NOW / HARNESS NOW.
Check WARNING: lines — they fire when a measurement is at/over a seat limit (transition now).
Use NEXT TRANSITION to answer "when": earliest of age-, weight-, and height-driven dates from a crude growth model (see references/growth-model.md).
For booster-age children, run through the 5-step belt-fit test verbatim — all five must pass.
The Four Stages (quick reference)

Stage Position Age guide Size gate Key rule

1. Infant/convertible Rear-facing birth–2+ y RF to seat max (often 40–50 lb) Max out the seat, don't race the birthday
2. Harness Forward-facing ~2–4+ y ≥40 lb typical floor Straps AT/ABOVE shoulders + top tether
3. Booster Forward-facing ~4–10 y until 4'9" + belt-fit pass Lap+shoulder belt only, never lap-only
4. Adult belt Back seat 8–12 y 5-step test passes Back seat until age 13

Common Pitfalls

Treating age 2 as the goal for turning. Age 2 is the FLOOR, not the target — keep rear-facing until the seat's RF limits are exhausted (many seats go to 40–50 lb).
Strap height direction. Rear-facing: at or BELOW shoulders. Forward-facing: at or ABOVE. This is the #1 harness error and flips at the transition.
Forgetting the top tether. Forward-facing installs need the tether even with lower anchors.
Boostering on height alone. A tall 3-year-old stays in the harness; maturity (sitting the whole ride) gates the booster as much as size does.
Mixing belt + lower anchors unless the seat manual explicitly permits both.
Expiring seats. Seats expire 6–10 years from manufacture (plastic fatigue) — check the label.
After any crash most manufacturers (and NHTSA) say replace the seat, even if it looks fine.

Example

Parent: "Daughter is 30 months, 24 lb, 31 in — grandma says she can face forward now."

$ python3 scripts/car_seat_pilot.py --birthday 2024-03-15 --weight-lb 24 --height-in 31
POSITION NOW: FORWARD-FACING (age floor passed at 24 mo)
SEAT NOW: convertible or combination seat installed FF
HARNESS NOW: 5-point harness + top tether
NEXT TRANSITION: Booster window opens (age ~4 + 40 lb) — 2028-03-15

Answer: yes, she may face forward (age floor passed), but she is ONLY 24 lb —
the harness stage continues for years; booster talk is ~2 years early.

Safety Note

Guidance basis: AAP 2018 policy statement, NHTSA, Safe Kids Worldwide. The child's seat manual and state law always supersede this tool. When in doubt, direct to a free certified car-seat inspection station (NHTSA's "car seat inspection station" locator).
