Abstract
A chair control mechanism is adapted to decrease a likelihood of the mechanism becoming unintentionally disengaged from a locked position. In particular, a control arm has locked position wherein a seat plate is restricted in movement relative to a main bracket and an unlocked position where the movement relative to said main bracket is allowed. A latch bar is biased against the control arm and the control arm is notched such that axial sliding of the control arm into said unlocked position is possible only after providing a force necessary to disengage said latch bar from said notch.
Claims9
A chair control mechanism with a latch comprising:
- an arm mounted in a main bracket for axial sliding between a first position and a second position;
- and
- a latch bar biased against said arm to increase the force necessary to axially slide said arm.
A method of retrofitting a chair control mechanism with a latching apparatus, where said chair control mechanism includes an arm mounted in a main bracket for axial sliding between a first position and a second position, said method comprising biasing a latch bar against said arm to increase the force necessary to axially slide said arm.
