Abstract:
A tiltable stool includes a seat support, a seat, and a tilt mechanism. The seat is mounted to an upper end of the seat support. The tilt mechanism allows the seat to tilt in a desired direction. The tilt mechanism includes a coiled wave spring, an upper spring retainer and a lower spring retainer, a fastener bolt, and a tilt limiter. The upper spring retainer and the lower spring retainer are disposed opposite each other to sandwich the coiled wave spring therebetween. The fastener bolt pivotably holds the upper spring retainer in position. The tilt limiter is disposed inside the coiled wave spring and is secured to either one of the spring retainers. The tilt limiter includes a conical surface thereon which contacts a contact surface when the seat tilts to a predetermined tilt angle. The upper spring retainer is secured to a lower end of the seat support.

Claim (Index 6):
The tiltable stool according to  claim 1 , further comprising:\n a rotatable flange ring disposed outside and concentrically with the coiled wave spring, the rotatable flange ring including four radially disposed sets of multi-level flange surfaces; multiple radially disposed stoppers secured to a bottom surface of the upper spring retainer; and a tilt angle adjustment lever operably connected to the rotatable flange ring to rotate the rotatable flange ring therewith, wherein a maximum tilt angle of the seat is adjustable by rotating the rotatable flange ring to position the flange surface of a particular height to meet one of the multiple stoppers.
