Patent ID: 7997652

Claim:
A control mechanism for a chair comprising first and second chair components which are movably interconnected so as to be movable relative to each other, said control mechanism including a stop mechanism mounted on said first chair component and a stop part on said second chair component which is engagable with said stop mechanism to selectively confine movement of said second chair component relative to said first chair component and thereby limit movement of said first and second chair components, said stop mechanism including a slide member which is slidable along first chair component and includes a respective engagement section engaged with said stop part such that relative movement of said first and second chair components effects sliding movement of said slide member in a slide direction, said stop mechanism further including a lock mechanism which is releasably engagable with said slide member to releasably prevent movement of said slide member and releasably confine movement of said second chair component relative to said first chair component, said lock member including a lock member which is engagable with said slide member in a locking direction transverse to said slide direction wherein said slide member and said lock member are movable one relative to the other between a locked position which prevents said sliding movement of said slide member and an unlocked position wherein said sliding movement of said slide member is permitted, said lock member including a manual actuator effecting said movement between said locked and unlocked positions.
