ABSTRACT:
Play-free longitudinal guiding means having rails than run inside each other, namely a lower rail and an upper rail that can be displaced in a sliding manner with respect to the lower rail, for securing seats in vehicles such as private cars. The play-free longitudinal guiding means is such that the lower rail features along its length wall parts that have the shape of alignment grooves, and the upper rail features wall parts which run parallel to the wall parts of the lower rail and are shaped into an alignment groove, and the alignment grooves of the upper and lower rails face each other and form a sliding alignment channel. In the sliding channel there are sliding elements which in the free-standing condition exhibit a larger cross-section than in the installed condition, and the sliding elements guide the lower and upper rails without any play.
