ABSTRACT:
Motorized operating mechanisms for vehicle portal closure members, such as windows, sunroofs, sliding doors, hatches, or convertible tops are common in modern automobiles. Inadvertent operation of such closure members, however, has been known to cause injury and entrapment when such a member is directed to close at an inappropriate moment. A vehicle entrapment prevention system is provided which prevents undesired and possibly injurious operation of such a vehicle portal closure member. Undesired operation often occurs when younger occupants, such as small children, accidentally trigger the operating mechanism, which can cause the closure member to entrap an unsuspecting victim. Such an entrapment prevention system ensures safe operation by determining the presence of a responsible operator through the use of various sensors, and permits operation of a portal closure member only in the presence of such a responsible operator.
