Locking system for a movable element of a seat of an automotive vehicle

摘要

The system for locking a movable element of a seat to a stationary element comprises a wall of a first one of said elements which is provided with a window into which a hook connected to the other element penetrates following an insertion direction substantially perpendicular to the wall and a resiliently retractable interlocking member constituted by a ring made of a wire of a material resistant to shearing. A shiftable part of the ring extends in contact with the wall across the window. The ring comprises two ends spaced apart from the shiftable part and oriented in a same axial direction perpendicular to the wall and around which the ring can be pivoted, the ends being offset one with respect to the other and the axes of the ends being maintained in a common plane which is stationary with respect to the support. The shiftable part is able to shift by an elastic deformation of the wire in a direction parallel to the wall and cooperates with the hook to provide reliable interlocking.
