Definitions

  • the invention relates to a lock assembly, with a catch consisting of a rotary latch and locking means for locking a striker of the lock assembly.
  • the locking means has a toggle lever arrangement, the toggle lever arrangement being biased at its dead center with a spring element.
  • the striker In a closed position of the lock assembly, the striker is at least partially enclosed by a recess in the rotary latch. In an open position, the striker lies against the rotary latch without being enclosed by the recess in the rotary latch.

The second lever arm is connected to the rotary latch via a third swivel joint.
  • Lock assemblies are used in the automotive sector to lock things like side doors, tailgates, hoods or folding seat backs. But lock assemblies are also used in other areas to lock folding elements to a counter element.
  • a lock assembly usually consists of at least one striker, a rotary latch and a locking element.
  • the striker When the lock assembly is in the open position, the striker can be moved relative to the rotary latch and the flap element connected to the striker can be opened.
  • the flap element When the flap element is closed, the striker is moved into a recess in the rotary latch, whereupon the rotary latch, which is rotatably mounted on a lock housing, is rotated and the recess encloses the striker at least in sections.
  • the locking means is then in engagement with the rotary latch, preventing the rotary latch from turning back. In this position, the movement of the striker for opening the flap element is inhibited.
  • an upstream pre-locking position can also be provided in the locked state.

  • the striker In a closed position of the lock assembly, the striker is at least partially enclosed by a recess in the rotary latch and thus its movement is inhibited.
  • the striker In an open position, the striker is released by the rotary latch.
