With recent posts on the Snowbird's incident, harnesses & FOD the following link to the UK AAIB's report into a fatal YAK-52 accident last year highlights how extraneous factors may all too easily combine to make the improbable possible.

While not explicitly stating which harnesses were subsequently tested ... it would appear logical that the larger the fittings the greater the potential to jam in the controls of either cockpit.
My own arbitrary ground check of a stock Russian harness suggested it was more likely to jam in the rear cockpit rather than the front.
However best to check your aircraft & form your own opinions ... regardless it will drive home the real risk of an unsecured harness as FOD, or indeed any other object falling into the control well under the seats.
The report makes salutary reading, which is why I've deliberately not gone into detail to encourage everyone to read it ... suffice to say a screwdriver was found (yet again), but not positively shown to be a factor ... it will be interesting to see if the CAA mandates further (cockpit) FOD barriers as a result.
Fly safe.
