Pneumatic door release for pneumatically actuable doors, especially pivoting or folding doors in vehicles serving for passenger transport, are provided with a reversing switch device triggerable by mechanical means and converting the door-closing movement into an opening movement when persons or objects are jammed in a closing door. Since the door, when it reaches the end position, comes to a stop by striking, the same effects as when a door strikes against a person can occur, with the result that there is the possibility that a reversal of the door movement out of the end position can take place in exactly the same way as a reversal when the door comes up against a person or an object. In order to prevent such a reversing movement of the door out of a closing or opening end position, mechanical means have been provided according to the invention. |
