A doorway, comprising:
- a door frame including a passage, a header, a first jamb and a second jamb, the passage extending laterally between the first jamb and the second jamb, and the passage extending vertically along the first jamb and the second jamb to the header;
- a door configured to move between a closed position and an open position, the door closing the passage in the closed position, and the door opening the passage in the open position;
- and
- a bumper configured to move between a deployed position and a stowed position, the bumper disposed in the passage and covering a portion of the door frame in the deployed position, and the bumper directly pivotally mounted to the header;
- wherein movement of the bumper from the stowed position to the deployed position is driven by gravity.
A doorway bumper for attaching to a header of a doorway, the doorway bumper comprising:
- a frame including a web, a first flange and a second flange, the web extending between and connected to the first flange and the second flange, the first flange projecting out from the web in a first direction to a distal end of the first flange, and the second flange projecting out from the web in a second direction to a distal end of the second flange, wherein the second direction is opposite the first direction, the frame configured as a length of Z-bar;
- a cushion attached to the web, the first flange and the second flange, and the cushion covering at least a first side of the frame, the cushion comprising a foam polymer material, and the cushion completely covering at least a bottom side of the frame;

- wherein movement of the bumper is driven by gravity as the door moves from the closed position to the open position and as the bumper is automatically deployed;
- and
- wherein the bumper comprises:
- a bumper frame including a web, a first flange and a second flange, the web extending between and connected to the first flange and the second flange, the first flange projecting out from the web in a first direction to a distal end of the first flange, and the second flange projecting out from the web in a second direction to a distal end of the second flange, wherein the second direction is opposite the first direction, the bumper frame configured as a Z-bar;
- a cushion attached to the web, the first flange and the second flange, and the cushion covering at least a first side of the bumper frame, the cushion comprising a foam polymer material, and the cushion completely covering at least a bottom side of the bumper frame;
