[已过期]Cosco Topside 儿童车载座椅

:因为孩子太小，安全带是按照大人的身高体重设计的，小孩坐在这种座椅上才能被安全带固定，而且不会被安全带伤害。比如小孩太矮，lap belt可能会勒到肚子，发生碰撞时伤害肝脏和胃；shoulder belt可能勒到脖子而不是胸部，小孩可能觉得不舒服就把安全带移到胳膊下面甚至背后，非常危险。 //@kubrick: 只知道法律强制必须使用 但一直不明白像这种年龄段的这种规格的安全座椅有啥实际保护作用？

:The booster seat boosts your child high enough for your vehicle's lap and shoulder belts to restrain her safely. Without a booster seat in the event of a crash, an adult seat belt can actually cause injury rather than prevent it. For example, if the lap belt rests on your child's tummy (which it's likely to do without a booster), she could suffer stomach, liver, or spleen damage in a crash. And if the shoulder belt rests against her neck rather than her chest, she may try to move it under her arm (where it could crack her ribs and damage internal organs) or behind her back (where it offers no protection at all against head, neck, and spinal injuries). //@kubrick: 只知道法律强制必须使用 但一直不明白像这种年龄段的这种规格的安全座椅有啥实际保护作用？
