Abstract
The present invention relates to crewseats for aircraft such as helicopters, and to thigh support and lumbar support mechanisms for such crewseats. The thigh support mechanism is a tilt plate hingeably attached to a base plate, and a locking tang extending downward from the tilt plate to engage a lock lug attached to the base plate. The lumbar support mechanism is a flex plate between the seat back cushion and the rigid back of the crewseat. The degree of bow in the flex plate can be adjusted by moving an adjustment lever up or down, thus rotating a cam shaft, and a lift cam attached to the cam shaft. The lift cam increases or decreases the amount of bow in the flex plate, according to the position of the adjustment lever.
