A closure device, especially for vehicle doors, possesses a rotary latch interacting with a closure pin, a releasable ratchet for arresting the door, and a motor-driven shutting aid, which moves the door into the closed position. A problem from safety aspects is activating the shutting aid if fingers or articles are still located between the door and the bodywork. In order to reduce the risk of injury or damage, when the release mechanism is actuated, the force flow between the drive of the shutting aid and the door to be closed is simultaneously mechanically interrupted. As a result of this measure, the rotary latch is immediately released and the door springs open.

1. A closure device for doors, including doors of motor vehicles, having a rotary latch (26) which interacts with a pin (12) for the locking of a door, a ratchet (24) which arrests the rotary latch (26) at least in the closed position of the door and which can be released with the aid of a release mechanism (52, 58), and a motor-driven shutting aid (18), whereby the door can be pulled over the last part of its closing travel into the closed position, wherein the force flow between a drive (16) of the shutting aid (18) and the door to be closed is interrupted when the release mechanism is actuated, with a first eccentric member (34) of the shutting aid (18) by which an intermediate piece (38) is actuated, said intermediate piece (38) acting on said rotary latch (26), the first eccentric member (34) is arranged on a multi-membered toggle lever (32) which is retained in a basic position by a preloaded spring (80), in which basic position the necessary shutting forces can be transmitted to the rotary latch (26), and which can be moved by mechanical engagement of the release mechanism (52, 58) into a bent-in position in which the first eccentric member (34) is out of its entraining position wherein the release mechanism (52, 58) has a manually or motor actuated actuating lever (52,66) which, in its open position, moves the ratchet (24) out of its engagement with the rotary latch (26) and bends in the toggle lever (32).
