Mechanism for retarding the speed of closure of the door of an automotive vehicle to prevent slamming and also to effect complete closure of the door after the same has been slowed. A hydraulic piston and cylinder cushioning device is utilized to slow the closure speed of the door to a predetermined low rate and a solenoid-actuated door closing device is utilized to effect a complete closing of the door after slowing by the cushioning device. The cushioning device may be mounted in the door of the vehicle and includes a plunger engageable with the door frame or body of the vehicle to decelerate the door during the last portion of movement thereof toward a closed position. The door closing device may also be mounted in the door of the vehicle and has a latch which coacts with a striker on the body of the vehicle to effect complete closure of the door. The solenoid of the closing device is connected to the battery of the vehicle through an electrical circuit and is effective when energized to effect movement of a lever, which engages and moves the latch to close the door. Electrical switches are provided in the circuit and arranged so that the solenoid is energized when the door reaches a partially closed position and deenergized when the door is completely closed. The door may be opened at any time by manipulation of the usual inside door handle or outside push button.
