<p>Two mutually displaceable rails have U-shaped areas, and are alternately hooked into each other so that three elongated channels are formed, in a lengthways guideway, esp. for adjusting devices for seats in vehicles. Guiding media, with rollers or slides, are sited between the rails. These guiding media are located in the channels (25-27) between the shanks (22,23) of the rails U-shaped pieces. In one channel, at least, they may comprise concave lengthways guide grooves (30) formed in both shanks. There may be such grooves in all the shanks. This is light and compact, but resistant, and affords a wide range of possibilities of attachment.</p> |
