Narrative:
I was seated in the crew rest seat for about 10 minutes when we experienced a sudden onset of moderate turbulence lasting approximately 15-20 seconds. The seat belt sign was on and an announcement was made for the flight attendants to remain seated. They remained seated for approximately 15 minutes and then one of them was brought to a crew rest seat with an injury to her left knee that required that she be seated. It was later determined that 2 other flight attendants were injured; but continued their service for the remainder of the flight. Our weather planning information had indicated a probability of turbulence during the first portion of flight near cruise altitude and it was decided to have the flight attendants remain seated until we could determine the flight conditions airborne. They had just been released and had not yet begun their service when the clear air turbulence was encountered.
