Abstract:
The present invention relates to a vehicle seat. The vehicle seat includes: a seat cushion in which a lower body of a user is located; a seat back connected to be foldable on the upper part of the seat cushion; and an airbag mounted on the seat back to be deployed if an impulse which is greater than a predetermined value is detected, wherein the seat back can be switched to be erected and switched to be folded onto the seat cushion.
Abstract:
A bending device for the pipe bending process is provided to increase the bending efficiency in the molding of various shapes of double pipes and to increase the formability. A bending device for the pipe bending process comprises: a clamp fixing a pipe and in which an axis of rotation is bent to the center; and a bending region supporting member(100) inserted into the bending region of the pipe bent by the clamp. If tensile force is provided to the longitudinal direction, a bending region supporting part(110) of the bending region supporting member is extended toward the external diameter corresponding to the inside diameter of the pipe. If the tensile force is canceled, the bending region supporting part is elastically restored.
Abstract:
A multiple resistance welding apparatus and method of metal sandwich panels are provided to prevent compaction of the internal structure and to regulate the thickness of the manufactured sandwich panel partly by adjusting the distance between two roller electrodes. A multiple resistance welding method of metal sandwich panels comprises a step of preparing a metal sandwich panel(500) composed of two outer panels(500a,500b) and an inner panel(500c) interposed between the outer panels, a step of making the metal sandwich panel pass through between a pair of first and second roller electrodes(100a,100b) which rotate in the opposite directions, a step of controlling the interval between the first and second roller electrodes to the fixed distance, and a step of generating the resistant heat at the compression point of the metal sandwich panel by compressing the metal sandwich panel passing through the first and second roller electrodes and applying current to the compression point.
