A vehicle seat device includes a seat cushion having a cushion front side and cushion rear side both running in the transverse direction of the seat device. The device also includes a seat back having two backrest edge sides opposite each other and each running in the transverse direction of the seat device. The seat back is arrangeable on the cushion front and rear sides of the seat cushion in order to change a seat direction. The seat back is mounted so as to be rotatable by at least 180° around a transverse axis in order to change the seat direction. At least one headrest unit is arranged on the seat back in a displaceable manner in such a way that it can be displaced beyond the backrest edge side facing away from the seat cushion in each case and can be displaced back under this backrest edge side.

A head restraint may include a support structure with an opening, adjustable flexible elongated members, and an adjustment mechanism. The elongated members may be attached to the support structure, may span the opening in the support structure, and may be configured to support a user's head. The adjustment mechanism may be configured to at least one of automatically and/or manually adjust tension of at least portions of the elongated members spanning the opening.

The technology can be embodied in a headrest that includes an enclosure that includes one or more acoustic transducers. The headrest includes a bar for mounting on a backrest of the seat, such that the mounted headrest is movable with respect to the backrest to different positions over an adjustable range. The bar includes one or more wires each of which is coupled to an electrical contact at one end, and an acoustic transducer at an opposite end, the one or more wires disposed within a hollow interior portion of the bar. The bar also includes an opening for permitting an electrical connection to be established between an electrical connector coupled to an external source, and the electrical contact coupled to the one or more wires. The connection is maintained over the adjustable range of the headrest by a mechanical bias on either the electrical connector or the electrical contact.

In accordance with at least one embodiment, an adjustable head and neck system comprises a locking upright brace and a forehead support. The forehead support is coupled to the locking upright brace. The forehead support is configurable to support a user's forehead.

A pad is adapted to set on a seat pan included in a vehicle seat. The pad includes a cushion on the seat pan and a cushion cover on the cushion.

A headrest element may have a central supporting region and two lateral supporting regions. The lateral supporting regions may be pivotable with respect to the central supporting region about a side pivot axis, which may run at least substantially parallel to a supporting surface of the central supporting region, in such a manner that an angle of the supporting surfaces of the lateral supporting regions can in each case be adjusted variably with respect to the supporting surface of the central supporting region. The central supporting region and the lateral supporting regions may be jointly pivotable about a transverse pivot axis, which runs at least substantially perpendicular to the side pivot axes, in such a manner that an adjustment of the supporting regions in the longitudinal direction of the vehicle is possible. A headrest using the headrest element is also described.

A headrest for a vehicle seat includes a padded part, carrying bars for securing the padded part to a backrest of the vehicle seat, and a mechanism for turning down the padded part about two swivel axes and from an in-use position into an out-of-use position. The mechanism comprises a cross member connecting the carrying bars to one another and forming the swivel axis of the padded part. Furthermore, the carrying bars and also the cross member run outside the padded part and the padded part is suspended on the cross member from the outside in a swiveling movable manner via the retaining strut and the double clip.

A headrest (1) includes a stay (6), a framework (2) supported by the stay (6) in a turnable manner toward a head of a sitting person, and supporting the head thereof, a shaft member (4) to be actuated in conjunction with the turning of the framework (2), and turning at a larger angle than a turning angle of the framework (2), and a coil spring (5) including a coil (50) wound around a pivot portion (47) of the shaft member (4) in a direction tightening the shaft member (4) when the framework (2) turns to the opposite side to the head side of the sitting person, and supports the head of the sitting person.

The invention relates to methods and a system for operating electrical drive units of seat components in a motor vehicle, preferably in the case of a detected pre-crash situation, wherein an optimum target position of a passenger for an imminent crash case is moved to (S1, S2) depending on a current position of the passenger, wherein, for this purpose, a rule strategy for coordinating the adjustment of the seat components is determined (S3) in order to actuate at least two of the drive units at the same time or directly in succession such that the required power of the drive units is minimized (S4).
