ABSTRACT:
A slide rail device for a seat, of the type mounted laterally of a seat cushion frame, which comprises an upper rail member fixed to the lateral side of the seat cushion frame, a lower rail member fixed to a floor, a seat belt anchor provided between the upper and lower rail members, and an engagement element. When a great degree of inwardly slant upward pulling force is applied via the seat belt anchor to the upper rail member, the engagement element effects an engagement action in response to at least one of upward and inward component forces composed by such inwardly slant upward pulling force, so that an intensive stress produced between the upper and lower rail members may be dispersed to the engagement element. Further, the upper and lower rail members are formed from a lightweight material with a reinforcing element to have a lightweight yet robust structure.
