A one-way damping system is provided for dampening the movement of a closure member when the closure member is moved in a first direction toward its opened position such that the closure member is opened at a controlled rate of speed, and for permitting the closure member to be moved in a second direction toward its closed position such that the closure member is able to be closed at an undampened or unrestricted rate of speed. The closure member includes a gear rack integrally molded therewith, and a rotary damper gear is movable into engagement with and out of engagement from the gear rack in order to provide the dampened and undampened movement modes. An idler gear or a pair of control arms are operatively associated with the rotary damper gear so as to ensure proper engagement and disengagement of the rotary damper gear with respect to the gear rack.

[ We claim:] [1.] A one-way damping system, comprising:a closure housing;a closure member movably mounted upon said closure housing for movement in a first direction toward an opened position with respect to said closure housing, and for movement in a second direction toward a closed direction with respect to said closure housing;gear means, comprising a gear rack portion having a plurality of gear teeth defined thereon, fixedly mounted upon said closure member for movement with said closure member as said closure member is moved between said opened and closed positions with respect to said closure housing;rotary damper means movably mounted upon said closure housing for movement between a first position at which said rotary damper means is operatively engaged with said gear means of said closure member for damping the movement of said closure member when said closure member is moved in said first direction toward said opened position with respect to said closure housing, and a second position at which said rotary damper means is operatively disengaged from said gear means of said closure member for permitting undampened movement of said closure member when said closure member is moved in said second direction toward said closed position with respect to said closure housing; andmeans operatively connected to said rotary damper means for engaging said gear rack portion and said gear teeth of said gear means so as to cause said rotary damper means to be moved to said first position at which said rotary damper means is operatively engaged with said gear means of said closure member and thereby dampen said movement of said closure member in response to said closure member being moved in said first direction toward said opened position with respect to said closure housing, and for engaging said gear rack portion and said gear teeth of said gear means so as to cause said rotary damper means to be moved to said second position at which said rotary damper means is operatively disengaged from said gear means of said closure member, so as to permit undampened movement of said closure member, in response to said closure member being moved in said second direction toward said closed position with respect to said closure housing.
