Abstract: A seat slide comprises a guide channel and a slide part which is attached to the seat and slides within the channel. To afford free sliding movement considerable play is provided between the slide part and the guide channel but to avoid rattle particularly when the seat is not occupied, resiliently deformable plastics pads are located in the clearance gaps between the channel and the slide part to take up the play. These plastics pads not only take up the play but also facilitate sliding movement in that they can be made of a material having a low coefficient of friction.
