Abstract
Such systems typically have an extendable rollover bar, which in its extended position is locked against being pushed back in by a locking pawl that is in operative locking engagement with a toothed segment. To make it possible by simple means to use both hands to return the rollover bar to its retracted position when required, the invention provides a reversing lever, which can be manually brought to a self-holding position above dead center while unlocking the locking pawl before the rollover bar is pushed in. This self-holding position can be automatically canceled again just before the rollover bar reaches its standby position.
