LONGITUDINAL GUIDE FOR A MOTOR VEHICLE SEAT

摘要

A longitudinal guide for vehicle seats, comprising a lower rail, an upper rail supported thereon to be displaceable in a longitudinal direction, wherein each upper rail and lower rail has an L-shaped region, if viewed in profile, formed by a base leg and an L-leg projecting from the base leg substantially perpendicularly, and two end regions respectively connected to the L-shaped region. Each elongate rail includes a first bearing area and a second bearing area for guiding means, which are biased to each other and formed by opposite end portions of the respective upper rail and portions of the associated lower rail. Embossments are formed at both ends of the base leg of the upper rail by cold work forming, with a smaller radius of curvature to effect higher stiffness of the longitudinal rail, particularly in event of a crash. Further embossments may be provided for an even higher stiffness.

1. A longitudinal guide for vehicle seats, comprising two elongate rails, each comprising a lower rail and an upper rail supported thereon so as to be movable in a longitudinal direction, wherein
each upper rail and each lower rail comprises an L-shaped region, if viewed in profile, which L-shaped region is formed by a base leg and an L-leg projecting from the base leg substantially perpendicularly, and two end portions which are respectively connected to the L-shaped region, the end portions of the respective upper rail and of the respective lower rail form diagonally opposite embracing areas under mutual interlocking, each elongate rail comprises a first bearing area and a second bearing area for guiding means, which are biased to each other and formed by opposite end portions of the respective upper rail and portions of the associated lower rail, wherein embossments are formed at both ends of the base leg of the upper rail by cold work forming, said embossments being formed with a smaller radius of curvature to effect a higher stiffness.
