ABSTRACT:
A pivoting gear damper for use with a rotary damper includes a toothed gear rack movable between a first position and a second position corresponding to movements in first and second directions. A pivotal bracket is provided for rotation between first and second positions corresponding to movements of the gear rack in the first and second directions. The rotary damper has a toothed driven gear disposed on the pivotal bracket. One-way dampening means is disposed on the pivotal bracket for causing the toothed gear rack to be in meshed engagement with the toothed driven gear to produce a dampening force when the gear rack is moved in the first direction and for causing the toothed gear rack to be disengaged from the toothed driven gear to allow unrestricted motion when the gear rack is moved in the second direction. The one-way dampening means is comprised of a guide pin and a cam member.
