ARM REST DEVICE FOR SEAT

摘要

The present invention relates to an arm rest device for a seat, capable of: easily rotating, at once, arm rests installed on the side surfaces of a seat from a vertical position to a horizontal downward position; rotating the arm rests horizontally downward rotated to a horizontal position in various angles by each step; rotating, at once, the arm rests rotated to the horizontal position to the vertical position; and upward adjusting angles of the arm rests in various angles from the horizontal downward position to the horizontal position to variously adjust angles of arms according to a body type of a user. The arm rest device for a seat comprises: a bracket which is coupled to one side frame in a seat; a cover plate which is coupled to the bracket to be spaced apart at a certain interval at the front of the bracket; a rest bar which is spaced apart at a certain interval at the front of the cover plate coupled to the bracket, has an axis coupling hole formed at one side thereof to be penetrated, and is vertically rotated based on the axis coupling hole; an angle adjusting unit which is mounted between the bracket and the cover plate to adjust a rotation angle of the rest bar; a first fixed shaft which is mounted at the back of the bracket; a second fixed shaft which is inserted into an axis insertion hole at the front of the rest bar to allow the rear end thereof to be inserted into the first fixed shaft; and a fixing bolt which penetrates the inside of the second fixed shaft at the front of the rest bar to be screw-coupled to the first fixed shaft and to fix the bracket, the rest bar, and the angle adjusting unit.
