Patent ID: 8246117

Claim:
A chair comprising: a base; a seat attached to the base; a back attached to at least one of the seat and the base; and at least one armrest apparatus attached to at least one of the back, the seat and the base, each of the at least one armrest apparatus comprising: an armrest member attached to at least one of the back, the seat and the base, the armrest member having a first aperture and a second aperture, at least a portion of the first aperture being substantially parallel to at least a portion of the second aperture a first plate positioned above the armrest member, the first plate having a longitudinal slot that is transverse to the first and second apertures, an armrest cover attached to the first plate, a resilient device positioned between the first plate and the armrest cover or between the first plate and the armrest member; a first member extending through the first aperture and the longitudinal slot of the first plate; and a second member extending at least partially through the second aperture and the longitudinal slot of the first plate; the resilient device being comprised of a resilient body positioned above a tapped plate, the resilient body having a first hole and a second hole and the tapped plate having a first hole aligned with the first hole of the resilient body and a second hole aligned with the second hole of the resilient body, the first member extending through the first hole of the resilient body and extending through the first hole of the tapped plate and the second member extending through the second hole of the resilient body and extending through the second hole of the tapped plate; and the first member being adjustably positioned within the first hole of the tapped plate and the first hole of the resilient body such that the first member is adjustable to loosen or tighten positioning of the resilient body relative to the tapped plate and wherein the second member being adjustably positioned within the second hole of the tapped plate and the second hole of the resilient body such that the second member is adjustable to loosen or tighten positioning of the resilient body relative to the tapped plate; and wherein adjustment of the positioning of at least one of the first member and the second member to adjustably loosen or tighten positioning of the resilient body relative to the tapped plate adjusts an amount of force needed to move or slide the first plate relative to the armrest member.
