Abstract
An actuating-arm drive is provided for cupboard doors. The drive includes an actuating arm that is hinged to a door and is subjected to the action of a spring. The actuating arm can be tilted over a pivoting area that is delimited by two end positions. The actuating-arm drive is equipped with at least one damper that damps the tilting motion of the actuating arm before the arm reaches either of the two end positions.

A support arm drive to be attached to a lid, comprising:
- a housing;
- a support arm having a first end to be hinged to the lid, and having a second end hinged to said housing such that said support arm is operable to pivot through a pivotal range limited by a first stop and a second stop;
- at least one damper for cushioning the pivotal movement of said support arm in a first cushion region at said first stop, and for cushioning the pivotal movement of said support arm in a second cushion region at said second stop, said support arm and said at least one damper being arranged such that said support arm is operable to move through a neutral region between the first cushion region and the second cushion region, wherein movement of said support arm through the neutral region is not influenced by said at least one damper;
- a control element connected in an articulated manner to said support arm, said control element having a curved control surface;
- a pressure component directly contacting said control surface, said pressure component being operable to move linearly through said housing;
- and
- at least one spring for applying pressure against said control surface of said control element via said pressure component, said at least one damper being located between said pressure component and a stationary stop of said housing.
