Abstract
A movable-window safety device for arresting upward movement of a power-driven window glass in a motor vehicle body in the event of obstruction in the window opening comprises a resilient channel for receiving the window glass and which is mounted in a rigid window frame. The base of the resilient channel comprises an electrical detecting member housed in a hollow chamber. The side walls of the resilient channel extend proud of the sides of the rigid window frame and carry curved-over outer lips and inner lips. An obstruction in the window opening is carried upwardly by the window glass and applies a force to one or other of the side walls of the resilient channel, according to whether the obstruction extends inwardly or outwardly of the window opening. The resultant force is applied to the detecting member. The detecting member may be part of a capacitor in the tuned circuit of an oscillator whose frequency correspondingly varies in response to the resultant movement of the detecting member and is detected to arrest the window glass. Instead, it could be a member whose electrical resistance is changed by the applied force and is detected by an appropriate detecting circuit to arrest the window glass. An additional hollow chamber is provided in the base of the channel to increase its resilience.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
