In all Cessnas larger than the 150/152 pay attention to positive seat locking. The aircraft should have a secondary seat restraint, but some do not. Understand what the plane you are flying has, and how to use it.
If no secondary restraint system, be very certain that you've locked the seat, and it is locked on the track.
If there is a little silver lever in a black housing inboard of the inboard pilot's seat track, that's good, but now know that you have to release that to get the seat back to exit [in a hurry].
It could also have an inertial reel seat belt up under the seat = normal operation.
Or, if a very new 172, new tracks which are much more safe.
Just understand what you have and how best to use it.
