A system may include an adjustable headrest assembly. The adjustable headrest assembly may include a headrest center bracket, a left vertical side plate track, a left headrest side plate assembly including a left headrest side plate, a right vertical side plate track, and a right headrest side plate assembly including a right headrest side plate. The left headrest side plate may be configured to move up and down relative to the left vertical side plate track based on the engagement of the left headrest side plate assembly with the left vertical side plate track. The right headrest side plate may be configured to move up and down relative to the right vertical side plate track based on the engagement of the right headrest side plate assembly with the right vertical side plate track.

Clutch-based adjustment mechanism for motorized multi-way seat adjustment An adjustment mechanism comprises multiple screw shafts (111, 112, 113) and a motor (150) for driving the screw shafts. Further, the adjustment mechanism comprises a clutch mechanism (160) for selectively engaging the motor (150) with one or more of the screw shafts (111, 112, 113). A rotation of one or more of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a first degree of freedom. A rotation of one or more others of the screw shafts (111, 12, 113) caused by the motor (150) translates into adjustment of the seat according to a second degree of freedom.

A headrest module for a motor vehicle seat includes a base component and a headrest mounted in the base component. The headrest is configured to be guided in a vehicle longitudinal direction so as to be extendable and retractable relative to the base component. The headrest further includes a fixing mechanism having a first fixing element with teeth and a second fixing element configured to be moved towards the first fixing element for engagement between adjacent teeth. Contact faces of the two fixing elements are configured such that an extension of the headrest is possible under the action of a force on the headrest in an extension direction. A movement of the headrest in a retraction direction is possible under action of a release mechanism of the headrest module configured to move the second fixing element out of the region between the teeth of the first fixing element.

A method for manufacturing a vehicle seat backrest comprises the steps of: providing first and second uprights of a backrest frame and a support member of an upper backrest adjustment device; positioning the first upright partly facing a first side face of the support member and the second upright partly facing a second side face of the support member; moving the first upright relative to the second upright along a transverse direction of the support member, in order to sandwich the support member such that the support member of the upper backrest adjustment device is mounted on the first and second uprights of the backrest frame so as to pivot about a transverse axis.

Adjustable headrest including a guide configured to be coupled to a seat; a head support coupled to the guide and configured to be movable along an adjustment path relative to the seat; and a slider having a surface defining a recess receiving the guide. A retainer is positioned to urge a surface of the slider against a surface of the guide, thereby maintaining friction between the surface of the slider and the surface of the guide. Additionally, the adjustable headrest includes a bracket that is fixable relative to the head support or fixed relative to the seat. The bracket has a mounting section positioned for fixation relative to the head support or for fixation to the seat and a guide receiving portion receiving the guide. The slider and the bracket are separate components and are formed from the same material or different materials.
