<p>The present invention relates to a mobile bracket combining structure for a vehicle backrest. An impact is primarily absorbed due to a combining wall unit of a backrest frame having an over-molded bracket insert-injected in both lower parts thereof and due to a combining structure between bent protruding plates of a mobile bracket. Accordingly, an actual impact applied to a coupling unit for coupling the over-molded bracket and the mobile bracket is reduced, so rigidity and impact resistance are greatly improved. The mobile bracket combining structure for a vehicle backrest according to the present invention includes a backrest frame which is injection-molded using a synthetic resin and has the combining wall unit in both lower parts; the over-molded bracket which is made of a metal material and reinforces the combining wall unit by being inserted in both lower parts of the backrest frame when the backrest frame is injection-molded; the mobile bracket which is made of a metal material, is combined with both lower parts of the backrest frame, and has one and more combining members interlocked with the combining wall unit; and a coupling unit which couples the over-molded bracket and the mobile bracket.</p> |
