Front seat belts

Front seat belts


The front seat belts are of the lap-and-diagonal type and can be operated by one hand. Each of the seat belts consists of a reel with mechanical tensioner (belt tensioner), mechanical sensor, strap, strap lead-through, strap guide, buckle tongue and anchor plate. The inertia reel is fitted with a locking system which on locking prevents further extension of the belt. The locking system is controlled by two independent activating systems, one of which is sensitive to vehicle retardation and the other to a certain degree of belt acceleration.

The upper anchorage point (strap guide) on the B pillar has five different positions for adjusting the height over a range of 94 mm. The advantage of this is that persons of short stature can adjust the belt to prevent it pressing against their neck. The anchorage points for the lap strap and buckle lock are on the seat frame. Consequently, the buckle is always in the same position relative to the seat, regardless of its fore-and-aft adjustment. The buckle lock has a double locking function so that when in the locked position the catch is blocked by a spindle. The spindle is opened by the regular release button. Different versions of the locks may be fitted, with or without an electrical system for the warning function on the dashboard.
