Narrative:

According to the captain and first officer there had been no reports of turbulent air at our altitude. As we passed through a patch of clouds; without warning; we experienced moderate turbulence lasting about 8-10 mins. The 3-TIERED cart; myself and the flight attendant I was working with; lifted off the floor approximately 1-2 inches. I landed on the floor by seat 5G and held on the metal bar at the floor of the seat until it was smooth enough to get up and take an empty passenger seat (2D). The other flight attendant I was working with was able to take an empty seat (3H) until it smoothed out. The business class galley was in disarray (ie; broken glasses; dishes; liquids on the floor; etc) and there were flight attendant and passenger injuries. We treated a few passenger for cuts with items from our first aid kit and we treated flight attendant injuries with ice and heat packs. No medical attention was required upon landing. I wish that there was more technology to detect the presence of clear air turbulence; but unfortunately; I know that there is not.
