ABSTRACT:
A slide rail device for a vehicle seat adapted for adjustment of fore-and-aft positions of the seat, comprising an upper rail fixed to the seat and a lower rail slidably fitted to the upper rail, with one end of a seat belt being secured to the upper rail, in which the lower rail encloses the upper rail, with such an arrangement that an upper inverted-U-shaped portion of the lower rail is disposed above a substantially U-shaped shoulder portion of the upper rail, a lateral wall portion of the lower rail is inclined in conformity with a direction of an upward pulling force exerted via the seat belt upon the upper rail, and the shoulder portion of the upper rail is so formed as to accommodate the end of the upper inverted-U-shaped portion of the lower rail, to thereby prevent the separation of the upper rail, from the lower rail.
