Here's some pictures from Kurts coverage of Interbike this year.
Looks like the set screws on the pawl ramp piece tighten down on the bushing giving it some friction on the axle. The pawls look like they get restricted down into the hub with a traditional pawl clip.
As long as there's more friction there at the "ramps" than the clip puts on the pawls, then everything will function fine.
The pawl ramps look like they function identical to the way the Eastern/Ezra hub works, in that as the pawls move forward they slide up on ramps on a washer next to them pushing them up to engage the ratchet ring.
The big difference between this and the Eastern, though is that the Blind has a totally different ratchet ring that has it's teeth spaced out a lot more to allow more slack at times. Makes me wonder though, if the slack stays consistent all the time?
