Narrative:
Had a bumpy flight (light to moderate chop) entire way from boston. Tried various altitudes, all to no avail. Finally found FL240 over chs to be completely smooth. It had been completely smooth for approximately 15 mins when I decided to turn off the fasten seatbelt light. About 3-5 mins after turning the light off, we instantly went from totally smooth air to moderate turbulence. Immediately turned seatbelt light on and coordinated with ATC for a lower altitude. FL220 was again smooth. Called flight attendants and they said they were shaken, but ok. About 10 mins later, they called us and said 2 flight attendants had been hurt and we needed paramedics to meet the flight. I believe this is a good example for never turning off the fasten seatbelt light and letting passenger get up totally at their own risk.

Title: A B737 PIC RPT ON RUNNING INTO UNEXPECTED TURB THAT RESULTED IN 2 FLT ATTENDANTS BEING INJURED IN CRUISE AT FL240 30 MI SW OF CHS, SC.
Narrative: HAD A BUMPY FLT (LIGHT TO MODERATE CHOP) ENTIRE WAY FROM BOSTON. TRIED VARIOUS ALTS, ALL TO NO AVAIL. FINALLY FOUND FL240 OVER CHS TO BE COMPLETELY SMOOTH. IT HAD BEEN COMPLETELY SMOOTH FOR APPROX 15 MINS WHEN I DECIDED TO TURN OFF THE FASTEN SEATBELT LIGHT. ABOUT 3-5 MINS AFTER TURNING THE LIGHT OFF, WE INSTANTLY WENT FROM TOTALLY SMOOTH AIR TO MODERATE TURB. IMMEDIATELY TURNED SEATBELT LIGHT ON AND COORDINATED WITH ATC FOR A LOWER ALT. FL220 WAS AGAIN SMOOTH. CALLED FLT ATTENDANTS AND THEY SAID THEY WERE SHAKEN, BUT OK. ABOUT 10 MINS LATER, THEY CALLED US AND SAID 2 FLT ATTENDANTS HAD BEEN HURT AND WE NEEDED PARAMEDICS TO MEET THE FLT. I BELIEVE THIS IS A GOOD EXAMPLE FOR NEVER TURNING OFF THE FASTEN SEATBELT LIGHT AND LETTING PAX GET UP TOTALLY AT THEIR OWN RISK.
