Abstract: In a motor vehicle having a front-hinged door 26 and an adjacent seat 10, a safety belt system, the safety belt comprises a lap strap 14, a shoulder strap 16 and a common strap 20 interconnected to form a three point safety belt. The free ends of the lap and shoulder straps 14 and 16 are connected to the rear edge of the door 26. The common strap 20 is connected to an inertia reel 28 mounted inboard of and adjacent to the bottom of the back of the seat 26. A puller strap 30 interconnects a point 18 on the safety belt with a point 32 on the vehicle so that, when the door 26 is opened the puller strap 30 applies a force to the shoulder strap 16, thereby displacing the junction 18 between the lap, shoulder and common straps 14, 16 and 20 out of the plane containing their anchorages 22 and 24 and the inertia reel 28.
