An improved head restraint is provided for a reversible seat that is movable between two use positions, namely a forward-facing position and a rearward-facing position. The improved head restraint automatically pivots to a fold flat position upon unlocking of the seat, wherein the head restraint is positioned in this fold flat position during reversing seat movement, so as to reduce the seat height and clear the vehicle headliner. The head restraint is cable driven and operably connected to the seat linkages that control movement of the seat cushion and seat back during reversing movement. As such, the seat movement articulates the head restraint so that the head restraint angles forwardly toward the occupant in the forward-facing position and rearwardly toward the occupant in the rearward-facing position, while permitting the head restraint to automatically articulate to the fold flat position during travel of the seat between these two use positions.

A seat (1) for transport vehicles with an articulated frame (2) capable of moving and changing shape between a neutral position N and a comfort position C, which comprises a headrest portion (21) mechanically linked by means of a connector (22) to a connection area of a backrest portion (23) that changes the height position thereof as the frame (2) moves from the neutral position N to the comfort position C thereof, the connector (22) being suitable for this change in height position to be transmitted, by means of mechanical drag, to the headrest portion (21), the headrest portion (21) being mechanically linked by means of an upper guide unit (31) of a guide system to the chassis (4) which is configured such that the inclination of both the headrest portion (21) and the backrest portion (23) increase the inclination thereof with respect to the vertical as the frame (2) moves from the neutral position N to the comfort position C thereof.

The invention relates to a motor vehicle seat for motor vehicles comprising an adjustment device for a backrest head adjustment, the motor vehicle seat having a backrest, which has a backrest frame as the first component of the backrest head adjustment and a backrest head as the second component of the backrest head adjustment, and an actuator. The backrest head is pivotably connected to the backrest frame and the actuator has a driving element and a movable element, the actuator being connected to the backrest frame and the backrest head and it being possible to carry out a linear movement by means of the actuator. The driving element of the actuator is rigidly connected to the backrest frame or backrest head and the movable element of the actuator has a guide element which engages in a guide arranged on the backrest frame or backrest head.

A vehicle headrest assembly includes a latch mechanism moveable between an engaged position and a release position. The vehicle headrest assembly also includes a shape memory alloy (SMA) release assembly operatively coupled to the latch mechanism to selectively move the latch mechanism from the engaged position to the release position. The SMA release assembly includes an actuator base including a pair of tracks defining a slot, the actuator base including a plurality of retaining tabs. The SMA release assembly also includes a printed circuit board (PCB) retained directly to the actuator base and disposed adjacent the plurality of retaining tabs. The SMA release assembly further includes a slide disposed within the slot and retained to the actuator base with the pair of tracks. The slide is moveable to contact and bias the latch mechanism to the release position upon energization and contraction of a SMA wire.

Reclining seat mounted on a foundation through first and second slides. The seat cushion is mounted on the first slide, and the seat back is mounted on the second slide. The slides, the seat cushion and the seat back are arranged to move together as one unit to have the seat recline. A head restraint is mounted at a top side of the seat back to follow and move with the back during movement of the back. The second slide has a non-linear curved shape to rotate the head restraint when the seat back moves. The curved shape rotates the headrest in a backward and downward direction when the seat back moves downward and the seat cushion moves forward, and vice versa. From the different seat positions, the head restraint follows the motion of the occupant as they move to the different seat positions.

A headrest has a base carrying the headrest on a seat, a head piece forming an abutment for a head, and a four-bar linkage including a first link and at least one second link therebehind in a direction of displacement. Each link is secured at one pivot with the base and at another pivot with the head piece such that the head piece is movable by the four-bar linkage relative to the base between a first end position and a second end position. An adjuster can alter and/or arrest the relative position between one of the links and the head piece, or between one of the links and the base. This adjuster has a first slotted link fixed on one of the first and second links, a second slotted link fixed on the head piece or the base, and a slide block engaged in slots of the first and second slotted links.
