摘要：With this safety beading or ledge the drive of, for example, a driverlesstransport vehicle can be switched-off on collision with an obstacle, and can be switched-on again after removal of the obstacle. The safety beading or ledge mounted along ashock-absorbing or impact edge of the transport vehicle is provided for this purpose witha plurality of similar contact elements which are disposed in series and touch one anotherat contact points in an elastically deformable, pre-stressed tube. During collision with anobstacle and deformation of the safety beading or ledge the contact elements performa rocking movement against one another, whereby contact is interrupted and the drive isswitched-off. After removal of the obstacle the elasticity of the tube effects a return intothe initial position, whereupon the contact points again touch and the drive is switched-onagain.
