大家好，在客運上看到呼籲繫安全帶的英文，如下
To ensure your own safety, please fasten your seat belt when seated here
to avoid a fine.
想請問的是when seated...是不是應該要寫做when seating才對？
我的理解，這部分是分詞構句，可改寫為
when you are seating here...或when you seat here....
但seat應該是主動，用分詞構句後要作seating才是吧？
請教各位，謝謝。

是說when you are seated 被安排到該座位的意思？
可是一般座位不都自己挑的嗎，有這種用法嗎

感謝各位，原來是我孤陋寡聞，seat確實有這樣的反身受詞用法：
She seated herself at her desk.
我應該先查辭典的QQ
-----
加上另一位熱心網友解說：
若你還無法理解就想成這樣吧
When (you are) seated (by yourself)
----
另外當seat當形容詞用則有這樣的用法：
Paul was seated at his desk.
而有些辭典則直接用動詞的被動來看，因此如果把這裡的seated當成動詞的過去分詞
表示被動，就可以有客運那段分詞構句的形式了。
感謝！
