Abstract: A tilting support or work bucket, or apparatus for an aerial lift including a support frame for supporting an operator. The support frame can have a seat for supporting the operator when in an upright position and a chest support having a portion above and forward of the seat for supporting a chest of the operator when in a forwardly downward tilted position while allowing arms of the operator to extend forwardly out of the support frame. A support member can be pivotably mounted to the support frame at a pivot joint that is located at an upper portion of the support frame when the support frame is in the upright position, for pivotably supporting the support frame. An actuator can be included for positionably rotating the support frame relative to the support member about the pivot joint between the upright position and the forwardly downward tilted position. Since the pivot joint is located in the upper portion of the support frame, pivoting of the support frame from the upright position to the forwardly downward tilted position moves a center of gravity of the support frame rearwardly in the direction of the support member.

Abstract: The present invention provides a sealing apparatus for a window shade that is vertically raised and lowered. The sealing apparatus can include a first side seal assembly having a first side air seal member that is vertically oriented. The first side seal member can be movably connected to a first side frame member by a first movable arrangement for moving the first side seal member laterally into and out of sealing position relative to a first side of the window shade.
