AIR REGISTERS INCLUDING A ROTATABLE SHUTTER

An air register including a blade member including a plurality of vertical blades and a side wall defining a rear opening, and a shutter rotatably coupled to the blade member, wherein rotation of the blade member in a rotation direction from a center state causes the shutter to rotate in the rotation direction and at least partially overlap the rear opening of the blade member, a rate of rotation of the shutter as the shutter rotates in the rotation direction is greater than a rate of rotation of the blade member as the blade member rotates in the rotation direction.
