    Only belts role case, the seat belt shoulder strap and cummerbund damage on the occupant has a significant effect as the increase in the stiffness of the strap, the HIC value of the occupant becomes small neck moments. The impact of the other occupant injury parameters obvious With cummerbund increase in, the HIC value of an occupant becomes large, while the the neck moments other parameters did not change significantly. The high stiffness of the shoulder strap and the low stiffness cummerbund can effectively reduce the head HIC value.

Adopt self-tapping screws used for non-metallic or softer metal, do not hit the low hole and tapping; self-tapping screws are poin ted, so as to "tapping"; ordinary screws are flat head, the same thickness.
Self-tapping screws: drill hole without tapping holes, screws and generally different, head for the sharp teeth from large, a bit like the No crumbs wire tapping without tapping screwed directly into the , metal and plastic usually use this method.point of load power supply
Is consolidation of the material, it can rely on its own thread, will be concretion body "attack - drill, squeeze, pressure" thread, to work closely with each other.
The self-tapping screws high hardness wide spacing thread, the thread depth, the surface is not smooth, wood screws contrast, another difference is more obvious, wood screws after the segment is not threaded. Wood screws fine thread, blunt tip and soft. Tapping screw thread coarse, sharp and hard.peak load power plant
