| 摘要 |
The invention relates to an item of furniture (1) with a safety mechanism to reduce the chance of injury to the user as a result of one part of the furniture being moved relative to another part of the furniture. The mechanism comprises spaced apart sources of electromagnetic radiation (8), detectors of electromagnetic radiation (9) and a control unit (5), wherein each source is associated with a detector (9), at least one of the sources (8) is associated with a plurality of the detectors (9), at least one of the detectors (9) is associated with a plurality of the sources (8). The control unit (5) is arranged to receive signals from the detectors (9), whereby the detectors (9) are configured to detect when an object is blocking the path between associated sources (8) and detectors (9), and the control unit (5) arranged to stop the movement of said one part of furniture with respect to said other part of furniture should an object be detected. <IMAGE> |
