Narrative:
The gear lever couldn't be raised and we quickly discovered by use of the abnormal checklist that the lever- latch circuit breaker was out. I believe that my shoulder harness clip became entangled with the breaker on taxi out or hit it after I released the harness during taxi in. In the past, other important breakers have been 'pulled' by the shoulder harnesses. Our company says use caution with the shoulder harnesses, but I believe they should be redesigned. Some aircraft have longer straps so that the clips can't FLIP into the circuit breaker panel. Again a case, albeit a minor one, of the pilot compensating for design flaws.
