SEAT WITH RECESSING SECTION

摘要

A seat back assembly includes a back frame and an adjustable support mounted to the back frame. The adjustable support moves between a first position and a second position with respect to the back frame. A stationary back cushion is mounted to the back frame and defines an opening sized to receive the adjustable support. When the adjustable support is in the opening, both the adjustable support and the stationary back cushion provide support surfaces for the back of an occupant of the seat. When the adjustable support is moved toward the second position to at least partially remove the adjustable support from the opening, the opening accommodates equipment of an occupant of the seat.
