Prevent mechanism that car seat locking became invalid and upper and lower slide rail is peeled off

The utility model relates to a prevent mechanism that car seat locking became invalid and upper and lower slide rail is peeled off, this mechanism comprises slide rail reinforcing plate, anticreep pinion rack, fixed bolster, retention spring, the fixed split pin of spring, safety belt fixing bolt, curb plate assembly and rivet equipment. The mountable of this mechanism is below present slide rail, and at normal working condition, this mechanism can keep opening the state, does not influence the normal sliding function of slide rail, and to the upon impact before the emergence, this mechanism can link firmly upper and lower slide rail as an organic wholely, prevents that the slide rail from producing locking inefficacy slip and the slide rail end is peeled off. 本实用新型涉及种防止汽车座椅锁止失效和上下滑轨剥离的机构，该机构由滑轨加强板、防脱齿板、固定支架、保持弹簧、弹簧固定开口销、安全带固定螺栓、侧板总成和铆钉组装构成。本机构可安装于现有滑轨下方，在正常使用状态，该机构可保持开启状态，不影响滑轨正常滑动功能，在发生前向碰撞时，该机构可将上下滑轨固连为体，防止滑轨产生锁止失效滑动和滑轨末端剥离。
