| 主权项 | 1. An interactive whiteboard system including a display surface and a projector, wherein a support structure includes a support arm which extends away from the plane display surface, wherein there is further provided a safety member for connecting the support arm to the support structure, the safety member being arranged such that in an overload condition of the support arm, the support arm pivots relative to the support structure in a controlled manner until a predetermined stop point is reached, wherein the safety member is provided with a point of weakness at the position where it joins the support structure, the point of weakness becoming broken by breaking in the overload condition, wherein the safety member comprises a tubular structure, wherein in the overload condition the point of weakness breaks as a result of a break in a material of the tubular structure. | ||
