The bearing seat 10 and the axial bearing 11 provide guidance for the rotating shaft 17 at the bottom of the air respirator bracket. The respirator bracket can freely rotate in a circle through the two guide assemblies at the top and the bearings at the bottom.

[0075] The present invention realizes the switching of two use states of the seat through a rotatable air respirator bracket. Fig.11 . Under normal circumstances, the return spring is in a contracted state, and the movable plate 22 keeps the air respirator bracket in the front position of the clamping device, which is convenient for taking and placing the air respirator. When riding in the seat, the occupant can use the control handle 28 to drive the pull rope to rotate the air respirator bracket 90°. At this time, the headrest and backrest are in the front position, which can provide support for the occupant's head, back, and waist, greatly improving the riding comfort. When approaching the rescue site, the occupant can release the pull rope through the control handle 28, and at the same time lean forward slightly. The air respirator bracket automatically resets under the action of the return spring. At this time, the air respirator turns to the front of the seat. The occupant can complete the wearing before the battle and quickly go into battle.
