Child safety lock override mechanism - For Woman Safety Woman safety is a major concern in present world and the related laws ensure that government also cares for it. Mostly in public taxies, there is possibility for the driver to harass women occupant by activating the child safety lock without her knowledge. Purpose of child safety lock is to prevent child in the rear seat from opening the door and fall from vehicle. This will cause severe injury to the child. When child lock is ON, Inside Door handle becomes inoperative and the child cannot open the door. Only way to open door is through outside handle. But there is possibility for Taxi driver to kidnap the woman customer by enabling child safety lock, so that inside handle becomes inoperative and make her get trapped in car. To prevent such cases in future, Ministry of Road Transport ordered the manufacturers to delete child safety lock for all commercial vehicles. But even then, Child in rear seat of a taxi (Without child lock) and women in non-commercial vehicles (With Child Lock) are still in danger. Child safety lock override mechanism eradicate above problem. Purpose of this invention is to override child safety lock during emergency. Vehicle’s door latch mechanism is designed such that when child lock is ON, child in rear seat cannot open the door, meanwhile helps the woman in emergency to open the door. The differentiating factor between child and a panic woman is “Operating effort”. In Child Lock ON condition door cannot be opened using less effort in Inside Handle (Effort applied by child is comparatively Low).There is a fake stop in Handle because of which child stop its operating stroke within it. But when High operating effort is applied, inside handle travel beyond its specified stroke, as a result child safety lock mechanism in door latch is override and makes the door open. This Override mechanism will not come into play during Child Lock OFF Condition. Hence irrespective of vehicles, this mechanism can be adopted considering both Woman and Child Safety.
