Abstract: The present disclosure relates to a securing element for securing objects, such as vehicle seats, or for clamping loads, such as luggage, to a bodywork component and a securing system having a securing element. In order to confer increased strength on the securing element and furthermore to be able to secure it to the bodywork component in an inexpensive manner with a connection of high strength being produced, it is proposed that it has a composition comprising a sheet metal component and an elongate reinforcement element, the reinforcement element being surrounded with respect to the longitudinal direction thereof at least in a region at least in a partially peripheral manner by the sheet metal component so as to be able to transmit force.

Abstract: A method for producing a vehicle body with a roof part, lateral roof frame parts, a roof channel provided between said components on each side of the roof, and also front and rear roof-structure transverse parts, obtains a simpler and more cost-effective connection of the roof part to the adjacent components, while avoiding disadvantages associated with thermal connections. The roof part and the lateral roof frame parts are fixedly connected to one another at least along the respective roof channel by beading/seaming. The same also applies to the connection of the roof part to the front and rear roof-structure transverse parts. The beading/seaming can additionally be combined with an adhesive or an adhesive tape.

Abstract: A method for determining damage to a rotor blade of a wind turbine, includes at least the following time-domain-analysis steps: measuring the vibrations of a rotor blade by means of an acceleration sensor; obtaining event-time intervals, in which the amplitudes of the measurements steadily exceed a threshold; obtaining the number of these event-time intervals in at least a predetermined analysis time interval; and sending an error signal, when the obtained number of the event-time intervals is above a predetermined threshold for a predetermined analysis time interval.
