<p>The slides enable the fore-and-aft position of a seat in a vehicle to be adjusted. A lower slide (11) is of generally channel section with sides which bend inwardly at (31) over ears (28) formed at the ends of the bar of the inverted 'T' section of the other slide (14). The ears and the turned-over portions are normally just out of contact with each other. Tracks for balls (29) are defined between the ears and the turned-over portions of the channel sides. There is no relative sliding but only rolling during normal fore-and-aft adjustment, but if excessive load is experienced in a collision deformation of the slides can occur, until the ears come into contact with the turned over portions (31) to provide resistance against further destruction of the slides along the whole overlapping length of the slides.</p> |
