  • the biasing member is protected from over compression by the compression limit cavity which only permits the biasing member to be compressed only a limited amount of distance.
  • the forced entry prevention device can be adapted to operate during closure operation, and with or without anti-pinch. For example, if the closure assembly is in operation toward the full up condition, without any abnormal force on the panel, the panel will move unimpeded until the full up condition is reached and power is terminated to the motor 35.
  • the panel moves toward the full closed condition a distance determined by the force, and the spring constant as described above. If the panel is being moved toward the full closed condition and an obstruction is encountered and the biasing force of the biasing member is overcome, the panel moves toward the full down condition a distance determined by the force and the spring constant as described above and terminate power to motor 35. As this occurs, the movement of the panel toward the full down condition causes the jam gear to engage the teeth of one or both the drive gear and the slave gear so that the panel is not able to move downward after the sector gear engages the drive or slave gear.
