Folding head restraint for motor vehicle has locking arms having locking device with locking recess that interacts with another locking device having locking plate that can be moved axially and is guided not to move in rotation direction

摘要

A support structure (2) has two supports (3,4) mounted to pivot around pivot axis and attached to framework of head restraint cushion (1). The supports have arc-shaped curves (10,11) attached to pivot axis by locking arms (17,18) having locking device (24) with locking recess that interacts with another locking device having a locking plate (30) that can be moved axially and is guided not to move in rotation direction. The locking devices and the locking plate are comprised in a locking mechanism (23) that locks the foldable head restraint in in-use position. The head restraint cushion is supported on the support structure, and a fixing bracket attaches the head restraint to the backrest of a vehicle seat. The supports extend through an opening (13) in the upper portion of the backrest. The pivot axis is used as the center of curvature of the arc-shaped curves of the supports so that the supports can be rotated around the pivot axis in unchanged path of movement without lateral movement.
