瞎扯淡
米国好多车都没有latch, isofix更是压根没听说过
警察给新家长上安全课的时候明确说的安全带和latch在安全性上是一样的
还扯什么预紧, 用安全带固定座椅也是要把安全带全扯出来然后慢慢放回去的 这样安全带就锁死了 跟latch差不多的
有功夫上网看看科普视频不行么…

【 在 iThinkPad 的大作中提到: 】
: 儿童座椅，一定要isofix标准的，下面2个卡子，直接卡到isofix上
: 上面还有一个卡子，用带子勾住isofix的上固定口
: 这样才结实

why?'

According to both the National Highway Traffic Safety Administration (NHTSA) and the American Academy of Pediatrics (AAP), the middle seat is safest for kids too. In fact, the NHTSA recommends that all children under the age of 13 ride in the back — ideally in the center. But there’s a major caveat to this recommendation: the middle car seat is only safest if a full seat belt (rather than just a lap belt) is used. So if you’re driving an older car without a full, 3-point seat belt, your children are better off sitting in a back window seat.

The rear center seat is also recommended as the best place for kids’ car seats. In fact, the AAP found that children in the rear center seat have a 43 percent lower risk of injury than children in the rear window seats. Check your state’s child-safety laws for more info on child restraint requirements.

: 不是司机背后的位置最安全么，放在那里，把左边门的儿童安全锁锁上，然后都从右边下，多好。
