A seat unit includes a light receiving circuit configured to output a pulsed light detection signal in two levels depending on a light reception, a switch input circuit configured to output a pulsed on-off signal in two levels depending on whether a switch mounted on the seat is turned on or turned off, a logic circuit configured to output a turn-on signal upon receipt of the light detection signal in a level indicating the light reception and the on-off signal in a turn-on level, a light emitting circuit configured to emit light upon receipt of the turn-on signal, and a delay circuit configured to delay the light detection signal. The switch input circuit cuts off, upon receipt of the delayed light detection signal in a level indicating no light reception, the power supply from a battery to the switch and to output the on-off signal in the turn-on level.

A tray bracket for car seat back is provided, including: a fixing unit, a hanging board, a tray, and a placement unit. The fixing unit is for fixing to at least one pillar on a car seat supporting a headrest; the hanging board has a back area and a front area with opposite positions. The back area is disposed with an array of positioning components with different heights. The fixing unit is engaged with one of the positioning components. The front area is distributed with several clips; the tray is pivotally connected to the bottom of the hanging board, the tray is tightly attached to the hanging board in the folded state, and can be horizontal and perpendicular to the hanging board when opened. The other side of the tray is provided with the placement unit, for placing a carton between the placement unit and the tray.

A rail assembly includes a track assembly, an elongate shaft mounted to the track assembly, and a carriage assembly received within the track assembly. The carriage assembly includes a body portion, an exterior surface of the body portion, a slider bracket fastened to the exterior surface of the body portion, and a gear box positioned within the slider bracket. The elongate shaft extends through the gear box.

A vehicle track assembly includes a conductive rail coupled to the track assembly. The conductive rail includes an electrically insulative substrate and one or more conductive strips attached to the substrate. The vehicle track assembly further includes a track-mounted component electrically coupled to the conductive rail. The track-mounted component includes a cantilevered biasing member and one or more electrical contacts. The cantilevered biasing member biases the one or more electrical contacts toward the one or more conductive strips to maintain an electrical connection between the one or more electrical contacts and the one or more conductive strips as the track-mounted component is moved along the conductive rail.

A track assembly for a vehicle seating assembly includes a track that defines a lateral channel and a central channel. The lateral channel is in communication with the central channel. A plurality of contact strips are coupled with the track and are positioned within the lateral channel. A rail cartridge is positioned within the central channel and is slidable along the track. The lateral channel is at least partially enclosed by the track and the rail cartridge. A support is operably coupled with the rail cartridge and extends from the central channel into the lateral channel. A plurality of contacts are operably coupled with the support and are configured to engage the plurality of contact strips.
