Abstract
A sliding safety gear designed to brake by gripping an elevator or counterweight guide rail includes a flexible frame surrounding the guide rail in the directions of the guiding surfaces of the guide rail. The frame is provided with a braking surface that meets a first guide surface of the guide rail when the sliding safety gear is braking. Attached to the frame is a force element that meets a second guide surface when the sliding safety gear is braking. The cross-section of the frame of the safety gear is substantially in the shape of the letter C. At least one of the ends of the jams of the C-shape is inside the C-shape.
