This extensible/contractible driving device includes a rotatable driving member configured to be rotated by drive force of a driving unit; a drive force-transmitting member connected to a leading end of the internal cylinder, configured to be driven by the rotatable driving member so as to move along a rotary shaft direction of the rotatable driving member; and an elastic member disposed in the periphery of the drive force-transmitting member, connected to the leading end of the internal cylinder, and configured to apply biasing force in the rotary shaft direction to the drive force-transmitting member. The rotatable driving member, the drive force-transmitting member, and the elastic member include an intervening member (24) stored in an inner space between external and internal cylinders, disposed in the periphery of the internal cylinder, and intervening between the internal cylinder and the external cylinder. The intervening member (24) includes a plurality of component parts (31a, 31b) having a length in a longitudinal direction of the external cylinder. One of the component parts (31a) is displaced relatively with respect to the other component part (31b) so that the intervening member (24) is opened widely outward. Accordingly, it is possible to suppress a problem of slidability caused by distortion in shape of the intervening member (24) and a problem of interference among the composing members.

A liftgate having an overmolded hinge point comprising a metal reinforcement overmolded with a polymer and having a compression limiter portion molded in. The compression limiter portion including a tubular portion for receiving a fastener encapsulated during overmolding and having overmolded gusset ribs extending therefrom during the overmolding process.

A non-contact obstacle detection (NCOD) system for a motor vehicle and a method of operating the non-contact obstacle detection system are disclosed. The NCOD system includes a main electronic control unit adapted to connect to a power source. At least one non-contact obstacle sensor is coupled to the main electronic control unit for detecting obstacles near a closure member of the vehicle. The control unit is configured to detect an obstacle and cease movement of the closure member in response to the obstacle being detected. Additionally, the control unit is configured to release a latch and apply power to a motor in response to the obstacle not being detected. The control unit is also configured to determine whether the closure member is in a full open position, and continue to apply power to a motor coupled to the closure member if the closure member is not in the full open position.
