Seat Belt Tensioner CG Lock - all cars.

Typical automotive-type seat belts do not tighten. They are designed to stay loose. The CG-Lock lets your automotive seat belt work like an aircraft seat belt: when you pull the lap belt tight, it stays as tight as you want. With a CG-Lock installed, you can easily tighten the lap belt portion of your seat belt by pulling up on the shoulder harness. The CG-Lock lets you remove as much slack from the lap belt as you want. A little tightness adds comfort on long trips or during turbulent off road driving. A lot of tightness provides a driver with better control during spirited or aggressive driving on 'track days' or off road. The shoulder harness stays loose (just like normal) so you can still easily reach controls on the dashboard.
