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 7):
The tiltable stool according to  claim 6 , further comprising:\n a positioning mechanism to guide and retain the rotatable flange ring in position, the positioning mechanism including:\n a guide groove formed in an outer circumference of the rotatable flange ring to guide the rotatable flange ring while changing the maximum tilt angle; \n multiple positioning holes defined adjacent to the guide groove in the outer circumference of the rotatable flange ring; and \n a spring-loaded ball lock disposed around the outer circumference of the rotatable flange ring, \n wherein the spring-loaded ball lock engages one of the multiple positioning holes to hold the rotatable flange ring in position when the maximum tilt angle of the seat is established.
