Abstract: This invention relates to a device and a method for recognizing collision of automatically moveable parts of furniture with obstacles by detecting a change in bend or a change in acceleration. This is carried out by a device for recognizing collisions of automatically moveable parts of furniture with obstacles, comprising a piece of furniture with at least one moveable part (1, 2, 31), wherein this part is a adapted to be moved relatively to the rest of the furniture in a non-manual manner, an automatic driving mechanism adapted to move the moveable part, a controller adapted to control the automatic driving mechanism, and a sensor (4) adapted to detect a collision with an obstacle during the movement of the moveable part and to transmit the collision to the controller, wherein the sensor is adapted to detect a change in bend or a change in acceleration of the moveable part.
