IMPACT BEAM FOR PASSENGER DOOR OF VEHICLE

摘要

PURPOSE: An impact beam for a passenger door of a vehicle is provided to effectively absorb impact energy and accordingly to secure safety for passengers of the vehicle by improving the hybrid impact beam. CONSTITUTION: An impact beam(110) mounted to a passenger door of a vehicle to absorb shock inserts and combines two side beams(111) to one central beam(112) and connects the both side beams and the central beam by a bolt or a rivet to improve impact energy absorbing performance. Polymer as teflon, nylon or polyethylene having low friction coefficient or lubricating oil as grease is coated over the contact surfaces of the beams comprising the impact beam to induce slide between the beams. A reinforcing member is inserted in the central beam to improve bending strength and prevent a local depression by buckling.
