Abstract
A powered lift gate for an automotive vehicle includes a lift gate door hinged to a vehicle body. A motor system which opens and closes the door is operated by a controller coupled to a primary obstacle detection system which senses operation of the motor itself, and by a secondary detection system which directly senses an object interposed between a margin of the door and the door opening panel. A pinch protection member interposed between a marginal zone of the door and the door opening panel includes a resilient element having sufficient strength to support an object positioned between the door and the door opening panel such that the primary obstacle detection system will be triggered when the door and motor develop a predetermined compressive force upon the object. The predetermined compressive force is selected to allow normal operation of the lift gate, without subjecting an obstructing object to excessive crushing force.
