Abstract
A rotary damper includes a damper motor and a damper housing in surrounding relationship to the damper motor. The damper housing has a connection piece for mounting the damper housing to a first mass. An articulated lever is swingably mounted in relation to the damper housing and connected to a second mass. The articulated lever has a lobe which is movable during a swinging motion of the articulated lever in relation to the damper housing along a movement path between two stops which are connected to the damper housing. A gear mechanism transmits and/or converts a relative rotational movement between the first and second masses to the damper motor for vibration damping.
Claims5
A rotary damper, comprising:
- a damper motor;
- a damper housing in surrounding relationship to the damper motor, said damper housing having a connection piece for mounting the damper housing to a first mass;
- an articulated lever swingably mounted in relation to the damper housing and connected to a second mass, said articulated lever having a lobe movable during a swinging motion of the articulated lever in relation to the damper housing along a movement path between two stops which are connected to the damper housing;
- a gear mechanism configured to transmit and/or convert a relative rotational movement between the first and second masses to the damper motor for vibration damping;
- and
- damping parts arranged on the stops in the movement path of the lobe, wherein the damping parts are helical springs.

- a gear mechanism configured to transmit and/or convert a relative rotational movement between the first and second masses to the damper motor for vibration damping;
- and
- damping parts arranged on the stops in the movement path of the lobe, wherein the lobe is trapezoidal in cross section to define two parallel trapeze sides and two slanted sides, with a shorter one of the two parallel trapeze sides positioned adjacent to the articulated lever, and with the slanted trapeze sides forming support surfaces for the damper parts.
