Abstract

A drive device for a movable furniture part including a support to be fastened to a furniture carcass, an actuation arm device mounted movably on the support and to be connected to the movable furniture part, an energy store for applying force to the actuation arm device, a damping device for damping a closing and opening movement of the actuation arm device, and an adjusting device for adjusting a force of the damping device, a damping start position in relation to an angle position of the actuation arm device, and/or in terms of a damping travel. The adjusting device includes an adjusting element coupled to the damping device such that an adjustment of the damping force, damping start position, and/or damping travel takes effect when the actuation arm device is damped during the closing movement, and when the actuation arm device is damped during the opening movement.

Dependent claims

A drive device for a movable furniture part, comprising:

a support to be fastened to a furniture carcass,
an actuating arm device mounted movably on the support and to be connected to the movable furniture part,
an energy storage mechanism configured to apply a force to the actuating arm device,
a damping device having a damper housing and being configured to dampen a closing movement and an opening movement of the actuating arm device, and
an adjustment device configured to adjust a relative position between the damper housing and the support such that the damping device is adjustable in terms of a damping start position in relation to an angle position of the actuating arm device relative to the support,
wherein the adjustment device comprises an adjustment element coupled to the damping device such that an adjustment of the damping force, of the damping start position, and/or of the damping stroke carried out by the adjustment device can be performed on the damping device both when damping the actuating arm device during the closing movement and when damping the actuating arm device during the opening movement.
