Door-stopping device for motor vehicles
A door-stopping device for motor vehicles, includes a door holder bar, a support housing including a passage for the door holder bar to pass through, and a locking unit disposed in the support housing, which includes two pivotally mounted locking levers. Each locking lever is pre-tensioned by a spring element towards each other and towards the door holder bar. Each locking lever comprises a locking element. The locking elements bear on mutually opposite sides against the door holder bar and are adapted to engage with the locking grooves on the door holder bar. For the door-stopping device to present diverse possibilities of design, to be manufactured in a cost-effective manner and to occupy only little space, the spring elements are arranged substantially parallel to the door holder bar.
