Abstract

A passenger entertainment system having direct coupled individual seat receivers. Direct coupling of receivers to the passenger entertainment power and intelligence information signals is provided through a seat track transmission line consisting of one or more conductors associated with the seat track and running parallel to the seat track.

Claims

1. An audio passenger entertainment system for transmission of receiver power and intelligence information to a plurality of receiver means associated with a respective plurality of seat units distributed along a seat track comprising in combination:

an electrically conductive transmission line extending along the length of said seat track and parallel therewith, said electrically conductive transmission line including an electrical insulator strip disposed between an electrically conductive strip and said seat track; and

,

electrical connector means disposed between each of said plurality of receiver means associated with each of a corresponding plurality of seat units distributed along said seat track and said seat track for making direct coupling by conductive contact therebetween.

2. The invention according to claim 1 wherein said electrical connector means comprises a conductive transfer probe actuated by a seat latch.

3. The invention according to claim 1 wherein said electrical connector means comprises a pincer like spring-loaded mechanism.
