A height adjustment mechanism for a chair that enables a height of a chair seat relative to a chair base to be adjusted electrically in a cost effective and reliable manner is described. The height adjustment mechanism includes an electric motor, an upper enclosure member, a lower enclosure member, and a limit switch. The lower enclosure member is coupled to the upper enclosure member, and the electric motor is coupled to at least one of the upper and lower enclosure members to telescopically move at least one of the upper and lower enclosure members relative to the remaining enclosure member. The limit switch is electrically coupled to the electric motor to limit an amount of telescopic movement of at least one of the upper and lower enclosure members.
A height adjustment mechanism for a chair, said mechanism comprising:
An adjustable chair comprising:
A method for assembling a chair including a height adjustment mechanism, the height adjustment mechanism including a drive mechanism, an upper enclosure member, and a lower enclosure member, said method comprising the steps of:
An apparatus configured to be coupled to a base for a chair, said apparatus comprising a drive mechanism, an upper enclosure member, and a lower enclosure member, said upper enclosure member coupled to said lower enclosure member, said drive mechanism configured to move at least one of said upper enclosure member and said lower enclosure member relative to the base, said drive mechanism comprising a drive shaft, an electric motor, a resistance-sensing switch, and a gear box, at least one of said electric motor and said gear box coupled to at least one of said upper enclosure member and said lower enclosure member, said gear box coupled to said electric motor and said drive shaft, at least one of said upper enclosure member and said lower enclosure member comprising a limit switch configured to control movement of at least one of said upper enclosure member and said lower enclosure member said electric motor coupled to said resistance-sensing switch, said resistance-sensing switch configured to control operation of said electric motor.
