is there any definition for "of some kind"

[kwfine]

Could you help me find a definition for the words "of some kind" in the following sentence:

"But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind."

Thanks in advance!

Welcome to the forums.

"Of some kind" = some form of seat belt [in this sentence].

Kind here means a group of something with similar characteristics, or a particular type of something.

Thank you so much for the help, Anglika!

I see that most often a noun, followed by "some" sometimes is countable, while sometimes it doesn't, for example:
"some people" in which people is a countable noun, while
the work in "some work" isn't.
why?

"Some" takes on various meanings, depending on the context in which it is used. Have a look here for uses: Cambridge Dictionaries Online - Cambridge University Press
