What is the function of a door opening limiter?

[CaliRose]

The function of a door opening limiter is twofold: firstly, it restricts the maximum opening angle of the door to prevent it from opening too wide, and secondly, it allows the door to remain open when necessary, such as when the car is parked on a slope or in windy conditions, preventing the door from closing automatically. Common types of door opening limiters include standalone strap-style limiters, while others are integrated with the door hinge, typically providing limiting functions when the door is fully or partially open. The working principle of a door opening limiter is as follows: the limiter bracket is secured to the car body via a mounting bolt, and the limiter box is fastened to the door with two mounting screws. When the door is opened, the limiter box moves along the limiter arm.
