Deformable sensor for powered vehicle window

摘要

There is disclosed a deformation detection sensor comprising: an elongate element (2) including a deformable wall member which defines a radiation transmission path; a radiation transmission source (4) positioned to transmit radiation along the radiation transmission path; and a radiation detector (6) positioned to detect the radiation transmitted from the source (4) along the radiation transmission path; the arrangement being such that a deformation of the wall member of the elongate element (2) at least partially interrupts the radiation transmission path, whereby radiation being transmitted along said path to the detector (6) is attenuated. Also disclosed is a motor vehicle having a body opening in which a closure member is movable towards a peripheral edge of the opening to close the opening, an electrically operated drive mechanism being provided to effect movement of the closure member. The peripheral edge of the body opening is provided with the above deformation detection sensor which may control said drive.
