1. A device for adjusting the position of a strap-return element of a safety belt between two end positions, said device adapted to be mounted in particular on a post of an automobile vehicle, and said device comprising:

  • a guide rail adapted to be fixed to said post and having a front side and a rear side, which is adapted to face said post, said guide rail being provided with a rack-shaped locking means;

    the strap return element comprising a first substantially planar portion and a second portion which is angularly offset relative to said first portion in a direction away from said front side of said guide rail;

    said first portion having two lateral wings extending toward said guide rail and located on each side of the latter, said first portion also comprising a blocking plate located between said wings and extending oppositely to said guide rail rear side and downwardly inclined toward the latter to cooperate with said rack-shaped locking means for locking said strap-return element in position; and

    elastic means, located between said blocking plate and said rail rear side and facing said first planar portion, for biasing said strap-return element so that, normally, said first planar portion bears against said rail front side and said blocking plate rests in contact, and in engagement, with said rack-shaped locking means, whereby, when said second portion is pushed in the direction of said rail front side against said elastic means bias, the strap-return element tilts about a junction of said first and second portion so that said first planar portion rotates away from said rail front side and so that said blocking plate is pivotally released from said rack-shaped locking means, thereby allowing shifting of said strap-return element along said guide rail.
