Abstract

Una disposizione circuitale per sorvegliare un elemento di riparo azionato da un motore elettrico quando si chiudono aperture, per esempio finestrini o tetti scorrevoli in autoveicoli, allo scopo di garantire sicurezza contro l'inceppamento presenta sensori per rivelare i parametri elettrici attuali del elettrico, per esempio il numero di giri del motore o la corrente del motore, e un'unità di valutazione (22) per riconoscere un inceppamento, la quale confronta i valori effettivi dei parametri con valori prescritti e, riscontrando differenze fra valore prescritto e valore effettivo caratteristiche per riconoscere un imprigionamento di oggetti, genera un segnale di comando per disinserire il motore elettrico o invertirne il senso di rotazione. Per garantire sicurezza contro l'inceppamento anche quando si chiudono piccole aperture residue, sono previsti un trasduttore di posizione (23), che rileva la posizione momentanea dell'elemento da azionare (11), e una logica di controllo (24), che confronta la posizione momentanea dell'elemento da azionare (11) con un valore memorizzato (s), caratteristico di un'apertura residua, e all'occorrenza provoca, per uno spostamento limitato, un processo di apertura che precede il processo di chiusura (figura 1).A circuit arrangement for monitoring a guard element operated by an electric motor when opening openings, for example windows or sliding roofs in motor vehicles, for the purpose of ensuring safety against jamming has sensors for detecting the current electrical parameters of the electric, for example the number of engine revolutions or the motor current, and an evaluation unit (22) for recognizing a jam, which compares the actual values of the parameters with the prescribed values and, finding differences between the prescribed value and the actual value characteristic to recognize an imprisonment of objects generates a command signal to disconnect the electric motor or reverse its direction of rotation. To ensure safety against jamming even when closing small residual openings, a position transducer (23) is provided, which detects the momentary position of the element to be operated (11), and a control logic (24), which compares the momentary position of the element to be operated (11) with a stored value (s), characteristic of a residual opening, and if necessary causes, for a limited movement, an opening process that precedes the closing process (figure 1 ).
