摘要

The on-board fitting has a horizontal side that provides a protecting edge and a vertical side provided with a clamping groove attachable to the lateral edge of a window sill. One of two springs arranged in the clamping groove is a compression spring (9) comprised of a wire that is lesser in thickness than the height of the clamping groove and a vertical bending height greater than the clamping groove height.
