Abstract: An aircraft passenger seating unit and aircraft seating arrangements including seating units, each seating unit configured as a window-facing seating unit or as an aisle-facing seating unit. Each individual seating unit including first and second laterally adjacent seats mounted on a common platform and oriented at an angle to a longitudinal aircraft axis. A forwardmost point of each of the first and second seats, when in an upright sitting position, resides along a plane common to both the first and second passenger seats perpendicular to the longitudinal aircraft axis to allow longitudinal alignment of rows and increased seating density.

Abstract: An aircraft passenger seat assembly and backrest unit attachable to a seat assembly, the backrest being pivotally attached or fixed, and the backrest unit including at least one frame member having adjacent weakened and intact sections provided along a peripheral edge, the weakened section having a first failure load and the intact section having a second failure load greater than the first failure load such that, when a load on a backside of the backrest unit exceeds the first failure load, the weakened section fails and the intact section deforms allowing a portion of the backrest unit to tilt forward beyond an upright sitting position to absorb impact energy.

Abstract: A layout of passenger seats in an aircraft cabin including a first passenger seat positioned in a forward-facing direction and parallel to an aircraft longitudinal axis, and a second passenger seat positioned to one side of the first passenger seat, in a forward-facing direction, and at an angle with respect to the aircraft longitudinal axis, wherein the second passenger seat is angled toward the first passenger seat.

Abstract: A vehicle including a frame, left and right wheels, and a leaning suspension system. The frame defines a longitudinal vehicle axis. The leaning suspension system includes a transverse beam, left and right damping members, left and right control arms, and at least one lean actuator. The transverse beam is coupled to the frame and pivotable about the vehicle axis. The left and right damping members are pivotally coupled to the left and right sides of the transverse beam. The left control arm is pivotally coupled to the left wheel and to the frame, and the right control arm is pivotally coupled to the right wheel and to the frame. The lean actuator is pivotally connected between the frame and the transverse beam. The lean actuator is configured to extend and retract to tilt the left and right wheels and to lean the vehicle while cornering.

Abstract: One method of the invention is for welding and includes obtaining first and second members each including an extrusion having a through hole and includes obtaining first and second electrodes each having an electrode portion. The second member is positioned to have the second extrusion nest in the first through hole against the first extrusion. The first electrode is positioned to have the first-electrode portion nest in the second through hole against the inside of the second extrusion. The second electrode is positioned to have the second-electrode portion contact the outside of the first extrusion. Another method of the invention is for welding and includes obtaining a tube having an end form and a member having first and second portions. The tube and the member are positioned with the end form contacting the first portion while leaving a recess between the end form and the second portion.
