Abstract: An automotive passenger seat belt contains a selectively energizable and de-energizable DC electrical outlet into which the passenger may plug various electrical entertainment devices, such as radios, stereos, electronic games and the like to receive operating power. Energization of the electrical outlet is controlled by a switch which is placed in its energizing position only in response to coupling of the two seat belt portions together, indicating that the seat belt is being used. The electrical outlet is automatically de-energized in response to decoupling of the seat belt portions. The electrical outlet has an adjustment to provide different DC voltages for different types of electrical devices which may be connected thereto. An optional remote indicator can also be connected to the switch to indicate whether or not the seat belt portions are coupled.
