Yes Chimbu, if I was about to touch down in trees or run through a fence or highway, I would definitely be pulling my harness another notch tighter.
Added: One company I worked for ditched a Cessna into the sea. Being the dodgy Cessna seatbelt design, the shoulder strap slipped off the piddly buckle before or during the impact, leaving only the lap strap restraining pilot. Head slammed into the panel. He later died in the arms of the other crewmember whilst in the water. Sometimes that harness just can't be tight enough when forced landing.
