FIELD: transport.SUBSTANCE: this invention relates to safety belt lock frame. Safety belt lock frame has opening for belt band passage. Opening 14 for passage of belt 15 features curved shape at opening edge 16 for retaining the belt 15 that has bending radius of frame part 10 acting on belt 15 equal to, at least, the thickness of frame central part 11. Frame part is curved at belt opening edge through, at least, 120 degrees, preferably, through 150 degrees while frame part acting at belt has no edges. Frame part acting at belt has bending radius equal to, at least, 2.5 mm, preferably, 4 mm. Curved shape may be made, in particular, by bending, butting, and grooving.EFFECT: higher safety and reliability, lower production costs.8 cl, 4 dwg |
