max_len = 10
strings = str.scan /.{1,#{max_len}}/

You never mentioned that you want word splitting.

irb(main):011:0> str = "Ein König mit Krone ist besser als ohne"
=> "Ein König mit Krone ist besser als ohne"
irb(main):015:0> str.scan %r{\S.{0,#{max_len - 1}}(?!\S)}
=> ["Ein König mit", "Krone ist", "besser als ohne"]

It seems your last two strings should be one.
