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.
