The disclosure relates to an armrest assembly and a vehicle having the armrest assembly. The armrest assembly is configured to be capable of holding a cup. The armrest assembly includes: an armrest body, wherein a cavity and an opening communicating with the cavity are arranged in the armrest body; a headrest, wherein the headrest is rotatably fixed to an end portion of the armrest body close to the opening, and a cup receptacle capable of receiving the cup is arranged on the back of the headrest; and a cup holder mechanism, wherein the cup holder mechanism has a cup holder arranged in the cavity, and the cup holder is ejectable from the opening to hold the cup. With the armrest assembly in the vehicle of the disclosure, the depth at which the cup is held can be increased, the holding effect can be improved, and the comfort and safety of the headrest can be ensured.

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.

A method of controlling tilting movement of a headrest of a seating arrangement of a vehicle, the method comprising: receiving a request for tilting movement of the headrest; determining if the headrest is attached to the seat by checking for the presence of at least one electrical component that is located within the headrest; and operating a tilt motor to commence tilting movement of the headrest in response to the request only if the or each component is found to be present.

A seat assembly includes a seatback with a frame assembly. A track member is operably coupled to the frame assembly. A carriage member is pivotally and slideably coupled to the track member between raised and lowered positions. At least one support rod having upper and lower portions is operably coupled to the carriage member for movement therewith. A headrest assembly is supported on the upper portion of the at least one support rod and is operable between extended and retracted positions. The headrest assembly includes a headrest bun with a downwardly extending lower portion. The seatback includes a receiving area extending inwardly from a front side of the seatback and extending downwardly from an upper side of the seatback. A portion of the downwardly extending lower portion of the headrest assembly is received in the receiving area of the seatback when the headrest assembly is in the retracted position.

A method of controlling movement of a first component of a vehicle, the first component being a squab or a bulkhead of a rear seat of a vehicle seating arrangement. The method involves receiving a signal indicative of a state of a second component of the vehicle and receiving a request to move the bulkhead so that the seat is in a folded condition. The squab of the rear seat is moved into engagement with the bulkhead of the rear seat prior to moving the bulkhead; and movement of the bulkhead is commenced in accordance with the request and in dependence on the signal indicative of the state of the second component.

A turnover mechanism is disclosed. The turnover mechanism includes a bracket assembly, a rotatable cam, a cam resetting component, a locking pawl piece, a rotating shaft, and a rotating shaft resetting torsion spring. The cam is axially disposed on the bracket assembly. The cam resetting component is connected to the cam and the bracket assembly. The locking pawl piece is axially disposed on the bracket assembly. The cam drives the locking pawl piece to move between a locked state and an unlocked state through forward and reverse movements. The rotating shaft is axially disposed on the bracket assembly and is provided with a locking tooth plate. When the locking pawl piece is in the locked state, a locking pawl in the locking pawl piece and a locking groove on the locking tooth plate are locked and engaged, and the rotating shaft and the bracket assembly are restricted from relative rotation by the locking tooth plate. When the locking pawl piece is at an unlocked position, the locking pawl in the locking pawl piece and the locking groove on the locking tooth plate are unlocked and disengaged, and the rotating shaft and the bracket assembly are rotatable relatively. The rotating shaft resetting torsion spring is connected to the locking tooth plate and the bracket assembly. The rotating shaft resetting torsion spring drives the locking tooth plate and the rotating shaft to rotate relative to the bracket assembly.

A frame assembly for a vehicle seat includes a headrest frame including at least one support pole extending downwardly from the headrest frame and a seatback frame having a central body and a pair of outer brackets extending outwardly from the central body in spaced relationship to one another. A crossbar extends between and is rotatable relative to the pair of outer brackets. The at least one support pole is secured to the crossbar for facilitating concurrent rotation of the headrest frame with the crossbar. A locking mechanism is operably interconnected with the crossbar. An actuator is movable from a first actuator position to a second actuator position to engage the locking mechanism and move the locking mechanism from a locked condition to an unlocked condition. A slide shaft extends between the pair of outer brackets and supports the actuator during movement between the first and second actuator positions.
