A child restraint system that is adapted to be mounted within a vehicle is provided. The distal peripheries of the nested end pieces are then welded to each other and the sandwiched and bonded portions are radially pinned. As a result, the previously known disadvantage in image forming apparatus such as contact residue images which are unduly caused by continual contact of the photoreceptors to image forming units and intermediate transfer belt can be obviated, as an example. A flexible conduit couples the motion sensor housing to the base plate, and the flexible conduit permits selective orientation of the motion sensor in various positions relative to the light fixture.
