Abstract:
1. A seat slide mechanism for vehicles, comprising: a lower rail which is securely fixed to a vehicle body and has a plurality of locking holes longitudinally formed in an inner side wall thereof in such a fashion as to be spaced apart from one another at equal intervals; an upper rail which is rested on the lower rail and is movable forwards and backwards together with a seat cushion frame, the upper rail having a plurality of through-holes formed in the inner and outer side walls thereof to correspond to associated ones of the plurality of locking holes of the lower rail; a locking assembly which serves to selectively perform a locking and an unlocking between the lower rail and the upper rail; and an operating lever which enables a locking and an unlocking of the locking assembly and has an operating bracket integrally coupled with each of both opposite ends thereof in such a fashion as to lengthily extend rearwards of the operating lever; a plurality of pin-shaped lockers arranged spaced-apart from and in parallel with one another at equal intervals such that the lockers can move forwards and backwards through the plurality of through-holes of the upper rail, and can fit at front end portions thereof into associated ones of the plurality of locking holes of the lower rail via the through-holes of the upper rail in a state where each of the lockers moves forwards through an elastic restoring force of a return spring wrapped around the rear portion thereof for elastic operation to a locked condition between the lower rail and the upper rail; a support means fixedly fastened to an inner wall of the upper rail and adapted to guidably support the plurality of pin-shaped lockers such that the lockers move forwards and backwards through the plurality of through-holes of the upper rail; and a pulling means hingeably coupled to the support means and having a plurality of fitting grooves formed at a front end thereof for allowing the plurality of lockers to be fit thereto and retained therein and a pressing end extending rearwards thereof, whereby the pulling means is pivotally rotate when the pressing end of the pulling means is downwardly pressed by the operating bracket so that the plurality of lockers are pulled rearwards to escape from the locking holes of the lower rail to an unlocked condition between the lower rail and the upper rail.
