Abstract
The invention relates to a lock, especially for automotive doors or flaps, comprising a rotary latch () with which a closing element () engages when the door is closed and which pivots the rotary latch () from an open position via a pre-latch position to a main latch position. The lock further comprises a catch () which, in a pre-latch position, engages with a pre-stop notch provided on the rotary latch (), and in a main latch position engages with a main stop notch provided on the rotary latch (). An actuating element () acts upon the catch () in the manner of a power-driven opening assistance. An actuating surface () which radially enlarges in the direction of rotation () effects the lifting of the latch () in a simple manner. A loaded lever on the lock prevents the catch () from re-engaging with the rotary latch () once the catch () is disengaged, in case the rotary latch () does not pivot to the open position due to a load. The inventive lock is inexpensive to produce and very reliable due to its simple design.
