摘要： An adjustable friction brake assembly may adjust a variable amount of frictional force required to translate or rotate a shaft, rather than merely locking or unlocking the shaft. The brake assembly includes a housing for internally receiving the shaft, the external portion of the housing including external threading leading into circumferentially spaced fingers extending axially and oriented radially inward to engage the shaft. The brake assembly includes a rotatable adjuster having an internally threaded throughbore for engaging the housing and directing the fingers radially inward to engage the shaft, thereby increasing the required frictional force. For example, by rotating the adjuster clockwise, the required force can be increased; similarly, by rotating the adjuster counterclockwise, the required force can be decreased.

摘要： A passenger seat may be configured to adjust between an upright seating position and a lie-flat sleeping position (which may include one or more intermediate reclined seating positions) via independent rollers attached to the seat pan, or seat bottom, and to the backrest. As the passenger seat transitions between the upright seating position and the lie-flat sleeping position, guide channels set into the left and right frame rails direct the movement of the independent rollers through the guide channels and thereby control the angles of the seat pan and the backrest throughout the transition.
