Automatic sliding door energy redistributing mechanism

A sliding door closure system comprising:

• a safety cushion device comprising a conical shape with a predetermined maximum width revolved along a longitudinal axis of the safety cushion device;
• a suspension configured to suspend the safety cushion device in a pendulous orientation;
• an anchor situated in a center of a vertical closure track of a sliding door, and configured to be coupled to and support the suspension suspending the safety cushion device;
• and,
• a sliding door;
• wherein the safety cushion device, the suspension, and the anchor are configured such that:
• when the sliding door is closed, the safety cushion device is selectably operated into a closure mode in which the safety cushion device is displaced out of the vertical closure track of the sliding door so the sliding door may abut a vertical track frame, and,
• when the sliding door is closing, gravity urges the safety cushion device into a safety mode in which the safety cushion device is disposed in a position separating the sliding door from a frame so that the safety cushion device absorbs and disperses energy of the sliding door.
