Claim:
An armrest device comprising: an armrest mount formed with a first pivot connecting portion; an armrest member formed with a second pivot connecting portion that is connected pivotally to said first pivot connecting portion such that said armrest member is pivotable relative to said armrest mount between first and second positions; and a locking unit mounted operably in said second pivot connecting portion, and including a press member that is accessible externally of said second pivot connecting portion, and a locking tab unit that projects from said press member; wherein said press member is operable to move from a locking position, where said locking tab unit engages said first pivot connecting portion to arrest pivoting movement of said armrest member, to an unlocking position, where said locking tab unit is disengaged from said first pivot connecting portion so as to permit pivoting movement of said armrest member between the first and second positions; said first pivot connecting portion including a pair of spaced apart confining walls; said second pivot connecting portion being disposed between and being pivoted to said confining walls of said first pivot connecting portion; said second pivot connecting portion being formed with a compartment for movably receiving said press member, and including a pair of spaced apart compartment walls that have said compartment disposed therebetween, each of said compartment walls being formed with a wall opening that is in spatial communication with said compartment; each of said confining walls being formed with an arcuate slide slot that is in spatial communication with said wall opening in an adjacent one of said compartment walls; said locking tab unit including a pair of locking tabs that project respectively from opposite sides of said press member, that project respectively through said wall openings in said compartment walls, and that extend respectively into said slide slots in said confining walls.
