Clutch-based adjustment mechanism for motorized multi-way seat adjustment An adjustment mechanism comprises multiplescrew 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 power actuated tilting head restraint assembly includes a head restraint mountable to a vehicle seat. The assembly also includes a power actuation assembly including an electric motor to adjust a rotational position of the head restraint, the electric motor programmed to adjust the rotational position at a first speed during manual adjustment of the head restraint and at a second speed upon detection of an imminent impact by an impact detection system, the second speed greater than the first speed.

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.

A headrest device includes: a front-rear movement mechanism that moves a moving member in a seat front-rear direction with respect to a base member supported at an upper end portion of a seatback; a head support section that is coupled to the moving member so as to be capable of rotating about an axis running in a seat left-right direction, and that includes a front face configuring a support face to support a head of a seated occupant; and an angle changing mechanism that includes a link member spanning between the head support section and the base member, the link member being rotated with respect to the base member about an axis running in the seat left-right direction by the movement of the moving member so as to rotate the head support section with respect to the moving member about an axis running in the seat left-right direction.
