Description

Technical Field

[0001] The present application relates to the field of fire fighting technology, and in particular to an air breathing apparatus bracket and a fire truck seat. Background Art

[0002] Air respirator - also known as stored gas gas mask, generally consists of compressed gas cylinders, straps, masks, etc., mainly used as personal respiratory protection device for emergency rescue and fire fighting in the fields of fire fighting, chemical industry, etc.

[0003] An air respirator generally places its compressed gas cylinder, strap, mask and other devices in a storage box, and then places the storage box on a storage rack in a fire truck. When performing firefighting work, the firefighter takes out the storage box from the storage rack, and then takes out the air respirator from the storage box and puts it on.

[0004] With regard to the above-mentioned related technologies, since the storage boxes are uniformly placed on the storage frame, the internal space of the fire truck is limited, so the firefighters in the car cannot get the storage boxes at the same time. When wearing the air breathing apparatus, they need to take the breathing apparatus out of the storage box for wearing. Since the time for disaster relief and firefighting is precious, the efficiency of taking out the air breathing apparatus in this way is low, which is not conducive to firefighting work.
