ABSTRACT:
A lockable tilting apparatus for the seats of chairs and which can be used selectively either for chairs which tilt backward or for chairs which tilt forward, comprising a base plate securable to chair seat and a stationary body member adapted to be supported by the pedestal of the chair, spring means supported by said stationary body member, means supported by said stationary body member mounting said base plate for tilting pivotal movement relative to said stationary body member, link means engaging and movable with said base plate against the restoring force of said spring means whereby said base plate is tiltably movable relative to said body member against the restoring force of said spring means; and wherein a locking apparatus which is actuatable by displacement of an operating lever between two terminal positions is provided for selectively locking the base plate against tilting movement or for releasing the base plate for tilting movement, characterized by a slide member mounted in said body member for sliding movement relative to said base plate, said slide member being selectively movable between said two terminal positions, said slide member having receptacle means for engagement by an operating lever whereby to effect movement of said slide member selectively between said two terminal positions, said receptacle means being accessible for engagement by said operating lever from either of two laterally opposite sides of said body member. This construction permits the tilting apparatus to be mounted on either chairs which tilt backward or on chairs which tilt forward.
