Claim:
A seat sliding apparatus for vehicles, comprising: a lever operable to facilitate a seat moving in forward and backward directions on a track wherein the track defines a plurality of first through-holes; a connecting bar pivotally supporting the lever on a fixture to permit operation of the lever; a guide bracket pivoting upward or downward in response to operation of the lever; a plurality of locking pins inserted into or extracted from said plurality of first through-holes by the pivoting of the guide bracket, wherein said guide bracket and pins are operatively engaged for movement in unison in inward and outward directions such that if one of the plurality of locking pins is unable to enter a first through-hole, said operative engagement prevents the remaining locking pins from entering the plurality of first through-holes; and a supporting member mounted to a transfer rail attached on lower portion of the fixture and pivotally supporting the guide bracket using a hinge pin, said supporting member defining a plurality of second through-holes for the operation of the locking pins, wherein the guide bracket is provided with a plurality of legs spaced apart from each other and engaging the locking pins, wherein the plurality of legs comprise first legs of a linear shape and second legs whose middle portions are bent in a semi-circular shape and lower portions are spaced out of plane from the first legs, alternating with each other, and wherein each of the plurality of locking pins comprises a first projection and a second projection, wherein the first projection and second projection define therebetween a space capable of receiving the second legs, and thereby providing said operative engagement.
