Abstract: A fixing structure for fixing a seat of a vehicle includes a fixing member which includes a locking section, a buffering section and a restricting section. The locking and restricting sections are provided with a thread for meshing with the thread of the locking passage, and the buffering section has no thread. The fixing seat includes a locking passage and a restricting space connected to the locking passage. The locking member is inserted through the cover and screwed into the fixing seat. When vibrations occur, the locking member will be unscrewed from the locking passage. However, in order to prevent the locking member from fully disengaging from the fixing seat, the buffering section is retained in the restricting space to prevent the thread of the restricting section from meshing with the thread of the locking passage, which prevents disengagement of the locking member in a vibrating condition.

Abstract: A desk assembly includes a desk top pivotably connected to a seat or the armrest of the seat, and includes an angle adjustment unit and a positioning portion. The desk top is flat and suitable for books or magazines put thereon. A rack is pivotably connected to the desk top and has a positioning unit. The rack is pivoted and positioned relative to the desk top so that the board-like electronic device such as cellular phone or board-like computer can be supported on the rack.

Abstract: A seat unit includes a seat and a dining board is slidably and pivotably connected to the back of the backrest of the seat. A display device such as a flat-board computer, a table PC, or an In-Flight Entertainment device, is connected to the bottom face of the dining board. The dining board is connected with two links which are pivotably connected to the legs of the backrest so that the dining board is pivoted and positioned horizontally. The dining board has operation members on two sides thereof so as to be slidably engaged with grooves in the reception member on the backrest. The dining board can be slid and stored in the reception member and the passenger behind the backrest can operate and enjoy the In-Flight Entertainment device.

Abstract: A high-strength aluminum-magnesium silicon alloy and its manufacturing process which includes a composition adjusting step to add vanadium (V) and zirconium (Zr) in an aluminum-magnesium silicon alloy to refine grains of the alloy; a material casting step, a material preheating step, a hot forging step and a heat treatment step to melt magnesium and silicon atoms into an aluminum base to cause a lattice distortion and achieve a strengthening effect and precipitate Mg2Si from the grains of the alloy, and the precipitated particles act as obstacles to dislocation movement. Therefore, the alloy product has a yield strength improved by 31%, the ultimate strength by 39%, the hardness by 34%, and the fatigue strength by 55%. Therefore, the alloy product can be used in components with a high strength requirement such as the aluminum alloy wheels and the control arms of a car suspension system.
