Abstract: An adjustable headrest bracket includes a base and a coupling member located on the base. The coupling member has two coupling ends to couple with two separated headrest brackets. Each of the headrest brackets has an insertion end insertable into a vehicle seat and a hinge end coupled on the coupling end. Each of the headrest brackets forms a swivel path about the hinge end and a horizontal moving path relative to the coupling member. Thereby the interval of the headrest brackets can be adjusted to be inserted into different types of vehicle seats.

Abstract: A signal receiving apparatus for a mobile video device in vehicles has an antenna embedded in a removable non-metal element (such as a bumper or a water tank grille) of a vehicle. The antenna has an exposed second connector corresponding to and coupling with a first connector of the mobile video device. The antenna is hidden in the vehicle without affecting the appearance of the vehicle and provides a desired signal receiving effect. By embedding the antenna in the non-metal element, electromagnetic interference does not occur. The coupled first connector and second connector can transmit signals and facilitate installation and removing.

Abstract: The present invention discloses a car headrest cover with protective and beatifying features, which is primarily used for a car headrest having a video device. By means of an accommodating space on the car headrest, a video device having a viewing window is installed on the car headrest at a position corresponding to the headrest cover. A protective unit is disposed on the headrest cover corresponding to the position of the viewing window, and a beatifying unit is disposed at the external surface of the protective unit. The foregoing components constitute a car headrest cover for protecting a video device, which has the dustproof, sun block, and anti theft features, and the beatifying unit with animal or doll styles can further adds an artistic effect to its appearance.

Abstract: Adjustment structure for television pillow, including a television frame, a board seat and a subsidiary board. The television frame is for accommodating therein a television and is mounted on one side of the board seat. The bottom of the board seat is formed with a guide slot for a support rod assembly of a seat to insert therethrough. A clip member clips and pivotally connects the support rod assembly with the board seat. The board seat can be forward or rearward tilted about the support rod assembly so as to adjust the watching angle of the television. The subsidiary board and the board seat are pivotally connected by means of a pivot rod and a clip body. The subsidiary board can be pivoted upward relative to the board seat to change the supporting angle for a neck. Accordingly, the watching angle of the television and the supporting angle of front seat pillow can be independently adjusted without conflicting with each other.

Abstract: Coupling structure for mobile video device provided with a signal terminal having multiple signal contact points as outputs of the mobile video device and provided with a terminal jack disposed in a seat and having multiple signal contact points corresponding to the signal contact points of the signal terminal. The signal terminal can be more easily and quickly inserted into the seat to couple with the terminal jack or extracted therefrom for service. The terminal jack is mounted on a multistage adjustment device so that the height of the mobile video device can be multistage adjusted.
