Didn't pull it downwards.
As for the force, the resultant is going to be directed through an imaginary point that bisects the angle between the length of belt going to the reel, and the other going over the shoulder of occupant, and down to the catch. So if you were to assume the seat belt as it goes towards the occupant's shoulder were parallel with the ground (which it isn't on my car, it actually points downwards slightly), then the resultant would be at 45 deg to the horizontal, hence the bending force.
I did exactly as decribed above - manually chucked my weight forward with a jolt just out of idle curiosity to see the inertia reel work.
