Narrative:

All or most passenger were seated. Flight attendants were gathered at the back of the aircraft preparing service carts for movement into the aisles. Slight bumps occurred, which was enough warning of upcoming turbulence, however, not time enough for captain to be able to use intercom, or enough time for all cabin crew to be seated. During the worst of the turbulence, one flight attendant was caught with her back up against a wall trying to brace herself. As she was standing there, her head was slammed up against the wall. All other flight attendants were either seated or braced against other objects. It is a common occurrence on this particular flight, that turbulence happens without sufficient warning time, and too quickly for appropriate movement about the cabin. There are areas of timely and almost expected turbulence, where we have learned that at a particular point in the service we will have to break for turbulence. However, there are additionally, always chances of occurring bumps, no way to tell throughout the flight, but knowing from past experience that they will happen. This entire incident occurred in less than a min.

Title: B767 CABIN RPT OF TURB.

Narrative: ALL OR MOST PAX WERE SEATED. FLT ATTENDANTS WERE GATHERED AT THE BACK OF THE ACFT PREPARING SVC CARTS FOR MOVEMENT INTO THE AISLES. SLIGHT BUMPS OCCURRED, WHICH WAS ENOUGH WARNING OF UPCOMING TURB, HOWEVER, NOT TIME ENOUGH FOR CAPT TO BE ABLE TO USE INTERCOM, OR ENOUGH TIME FOR ALL CABIN CREW TO BE SEATED. DURING THE WORST OF THE TURB, ONE FLT ATTENDANT WAS CAUGHT WITH HER BACK UP AGAINST A WALL TRYING TO BRACE HERSELF. AS SHE WAS STANDING THERE, HER HEAD WAS SLAMMED UP AGAINST THE WALL. ALL OTHER FLT ATTENDANTS WERE EITHER SEATED OR BRACED AGAINST OTHER OBJECTS. IT IS A COMMON OCCURRENCE ON THIS PARTICULAR FLT, THAT TURB HAPPENS WITHOUT SUFFICIENT WARNING TIME, AND TOO QUICKLY FOR APPROPRIATE MOVEMENT ABOUT THE CABIN. THERE ARE AREAS OF TIMELY AND ALMOST EXPECTED TURB, WHERE WE HAVE LEARNED THAT AT A PARTICULAR POINT IN THE SVC WE WILL HAVE TO BREAK FOR TURB. HOWEVER, THERE ARE ADDITIONALLY, ALWAYS CHANCES OF OCCURRING BUMPS, NO WAY TO TELL THROUGHOUT THE FLT, BUT KNOWING FROM PAST EXPERIENCE THAT THEY WILL HAPPEN. THIS ENTIRE INCIDENT OCCURRED IN LESS THAN A MIN.
