Passenger control unit with security control

摘要

A multi-passenger vehicle having individual video devices (20,23) for each passenger includes a hand-held control unit (18) for the video that is removably mounted in the passenger seat structure (10,16) to enable a passenger in one seat to remotely control the video mounted in the seat directly ahead of the passenger to perform a number of different functions including selecting video or audio channels and playing video games. The video display device (20,22) includes an infrared receiver (60) that receives and responds to infrared signals transmitted from an infrared transmitter (50) contained in the hand-held control unit. The hand-held passenger control unit is removably mounted in a recess (40) in the passenger seat arm (16), and an electrical sensor (54,56) is provided for security purposes to remotely signal when the passenger control unit is installed in the seat arm. The video display device includes a seat electronics box (24) that is cable (30) connected to a remote signal source where the hand-held control unit includes a telephone handset. A telephone unit (70) is mounted in the display device to both receive and transmit infrared signals to carry voice communication to and from the passenger control, and the latter then also includes an infrared receiver (74).
