Kettler Junior chair question

Does this chair come with a seatbelt? And if so, can it be used WITHOUT the infant bar? I'm thinking of ordering this seat for Conner, but the pictures I've seen of it look like the only restraint is the crotch strap that attaches to the infant bar. But since Conner's two year old we won't be using the infant bar and I'm not sure he would stay in place unrestrained. Someone posted in another thread that it comes with a separate 3-pt harness-- can someone confirm this?
