ABSTRACT:
A wheel chair lift device includes a lift car selectively elevated above a base, along with protective skirting covering the region below the lift car. Exposed portions of the protective skirting subject to lateral inward deformation are provided with skirt deformation sensors for detecting abnormal inward deformation of such skirt portions. The skirt deformation sensors include a spring or other elongated deformable member that extends generally parallel and proximate to the portion of the skirt being sensed. A sensor detects that the elongated member has been laterally displaced from its usual longitudinal axis and generates an electrical signal. In response to such electrical signal, the lift device stops further movement of the lift car.
