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 rear-center head restraint system for an automobile vehicle includes a rear seatback of an automobile vehicle. A head restraint assembly is mounted on the rear seatback and is moved between a stowed position and a deployed position. The head restraint assembly includes a forward head restraint portion displaced from the stowed position in an upward direction and in a forward direction with respect to the rear seatback. A rear head restraint portion is positioned rearward of the forward head restraint portion and is displaced in the upward direction as the forward head restraint portion displaces away from the stowed position. At least one headrest post is fixedly positioned within the rear seat back. A release mechanism connected to the at least one headrest post is operated to release the head restraint assembly from the stowed position.

A seat frame of a vehicle including: a main frame, one end of which is connected to the vehicle to be movable forwards and rearwards and an opposite end of which is connected to a loop of the vehicle such that a height of the main frame is adjusted upwards and downwards; an auxiliary frame provided in an interior of the main frame and connected to the main frame to be rotatable with respect to the main frame by a predetermined angle so as to be unfolded and folded such that the auxiliary frame acts as a seat when being unfolded and acts as a partition that partitions an interior space of the vehicle when being folded; and a rail, in which the main frame is fitted and which acts as a path, along which the main frame moves to the front and rear sides of the vehicle.

A rear-center head restraint system of an automobile vehicle includes a rear seatback of the automobile vehicle. A head restraint assembly is rotatably mounted to the rear seatback and is moved between a stowed position and an in-use position. The head restraint assembly includes a rear head restraint body defining an L-shape and includes a forward-facing surface moved toward a head of an occupant at the in-use position. At least a first link and a second link are rotatably connected to the seatback. The first link and the second link are also rotatably connected to the rear head restraint body. A release system rotates the head restraint assembly selectively between the stowed position and the in-use position.

A latch assembly of a seat is provided in a vehicle. The latch assembly includes a base including a first pin and a second pin. A first latch includes a first housing and a first latch mechanism at least partially enclosed within the first housing. The first latch is pivotally coupled to the base. A second latch includes a second housing and a second latch mechanism at least partially enclosed within the second housing. The second latch is pivotally coupled to the base. The first latch is disposed in its latched position when the first latch engages the first pin, and the second latch is disposed in its latched position when the second latch engages the second pin. The first latch and the second latch are not disposed in their respective latched positions at the same time.
