Seat Belt Retractor: Description and Operation
Seat Belt
The outboard safety belt for the front and rear seats is a continuous-loop three-point system. The combination lap and shoulder belt (continuous-loop)
uses a common slip tongue.
The shoulder harness retractor is designed to let the webbing move freely in or out at all times, except during vehicle hard braking, hard cornering or an
impact of 8 km/h (5 mph) or more, when it is automatically locked by a mechanically actuated inertia sensor.
