Abstract:
A movable-window safety device for detecting a presence of an obstruction in a window opening closable by a power-driven window glass, comprising resilient material forming a resilient channel for mounting in a rigid window frame and for receiving an edge of the window glass when so mounted, the resilient channel having a base, a mouth and two side walls and being dimensioned so that the two side walls have extensions beyond the rigid window frame whereby an obstruction entering the window opening from either side thereof is moved into contact with a respective one of the extensions by the window glass when the window glass is power-drivingly moving and applies a force through said one extension to the respective side wall and directed towards the base of the resilient channel, electrical detecting means mounted within and extending along the rigid window frame so as to be acted on by the force and to produce a corresponding electrical signal, the width of the electrical detecting means extending substantially across the width of the resilient channel so as to respond to the force applied through either of the extensions, control means responsive to the electrical signal to arrest power-driven movement of the window glass, the electrical detecting means being mounted within a resilient enclosure in the base of the resilient channel, and wherein the resilient material forming the base of the channel is provided with at least one hollow chamber to increase its resilience, this hollow chamber being additional to the resilient enclosure in which is mounted the electrical detecting means.
