Sears has joined the Sky Blues to the end of the season.
"The aim is to try and play as many matches as I can," Sears told whufc.com. "With the new boys coming in, Benni [McCarthy], Mido and Ilan, it will be a bit difficult for young players like myself to maybe get a chance. Frank is the same, he has just gone to West Brom on loan, but it is all to get experience and matches under our belts."
Sears played 19 times for Coventry's league rivals Crystal Palace earlier in the season before a couple of matches last month back at West Ham.
"My time at Crystal Palace was worthwhile," he said.
"I felt I came back to West Ham stronger and that is what I want to do again. Palace was local, this is slightly further away but still not that far from home, as well as the football.
"You get to experience this, so it is all good for me at this stage of my career. Getting some goals in the bag would be good, I am looking forward to trying to do that."
