A method for adjusting a vehicle seat includes moving each of a set of first valves respectively associated with ones of a group of first bladders into an open position allowing the receipt of air into and fluidic communication among the group of first bladders, inflating the first group of bladders to a predetermined pressure, and closing each of the set of first valves to maintain an inflation level of each of the first bladders.

A headrest assembly according to an exemplary aspect of the present disclosure includes, among other things, a head restraint including a push-button and a cam rotatable by a pull cable. The head restraint is moveable from an upright position to a folded position by movement of the push-button or the cam.

A vehicle seating arrangement includes first and second seating assemblies that are each equipped with a seat and a seatback. A surface of the seat of the first seating assembly is vertically above a surface of the seat of the second seating assembly. A forward extreme of the first seating assembly is displaced rearward of a forward extreme of the second seating assembly.

A device for fastening a headrest to a backrest of a vehicle seat comprises first and second guide units for receiving first and second headrest columns. First and second receiving units fixed on the backrest receive sleeve-like portions of the first and second guide units. The second guide unit comprises a locking mechanism for locking various vertical positions of the second headrest column relative to the second guide unit. At least one rib is arranged on an outer lateral surface of each sleeve-like portion. At least one recess, in which the rib of the respective guide unit engages in a positive locking manner, is arranged on each receiving unit. A width of the rib of the first guide unit is greater than a width of the recess of the second receiving unit.

The technology described in this document can be embodied in a system that includes a seat headrest enclosing at least one first acoustic transducer that generates audio output in a first frequency range. The system also includes an adjustable headrest wing disposed in front of the seat headrest, the headrest wing being pivotally coupled to the seat headrest and adjustable to one of multiple positions. The headrest wing includes at least one second acoustic transducer that generates audio output in a second frequency range that includes frequencies higher than the upper end of the first frequency range. The system further includes a controller configured to adjust, for a given position of the headrest wing, one or more parameters of at least one of: (i) the first acoustic transducer and (ii) the second acoustic transducer in accordance with a target acoustic distribution.

A shape memory alloy (SMA) controlled hinge assembly is provided, including assemblies and combinations for adjusting a shape or position of an occupant support component, such as a vehicle seat support component or other seating component. The assembly includes an occupant support component and a hinge assembly configured to adjust a shape or position of at least a portion of the occupant support component. The hinge assembly includes a stationary plate and a movable plate rotatable relative to the base plate about a fixed axis of rotation. The hinge assembly includes a shape memory alloy wire coupling the stationary plate with the movable plate. An actuator is provided and configured to transform the phase of the shape memory alloy wire. In various aspects, the occupant support component is selected from one of a seat bottom; a seatback; a seat bolster; a seat head rest, and the like.
