Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for mounting an air respirator in a fire engine.

[Prior art]

Conventionally, when an air respirator is installed (attached) in a rear part of a fire engine, for example, as shown in FIG.
The seat back 1a of the rear seat 1 can be moved up and down, and the body rear wall 2 at the rear of the rear seat 1 is extended rearward to form a housing portion 3, and the air respirators 4 to 4 can be attached to and detached from the housing portion 3 by one-touch operation. The mounting belts 5 to 5 are used for mounting.

[Problems to be solved by the device]

For this reason, the air respirator 4 cannot be attached or detached unless the seat back 1a of the rear seat 1 is lowered and the respective attachment belts 5 are removed, and in particular, the removal of the air respirator 4 at the fire site (removal from the vehicle body) Also, it may not be possible to quickly carry out activities in an emergency because it takes time to put on (wearing firefighters).

The present invention has been made in view of the above problems,
An object of the present invention is to provide an air respirator mounting structure in which the air respirator can be easily attached and detached, and the air respirator can be prepared for mounting before reaching a fire scene.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, a backpack-type air respirator is removably installed on the stepped portion of the body formed behind the seat cushion of the seat of the fire engine, with the backrest portion as the front portion. This air respirator also functions as a seat back for the seat.

[Effect of the device]

In the mounting structure of the air respirator according to the present invention, the air respirator also functions as the seat back of the seat, so that the seat back is not required, the cost can be reduced, and the air respirator can be easily attached and detached. In addition, it is possible to eliminate the mounting space conventionally required for the seat back and effectively use the space.

Also, since the air ventilator can lean directly against the back of the air ventilator, crew members (firefighters) can wear the air ventilator in advance before arriving at the fire site. Be prepared for activities.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 schematically show a rear seat portion of a fire engine, in which a body rear wall 12 behind a seat cushion 11a of a rear seat 11 is slightly above the seat cushion 11a from a passenger (fireman). ) A portion 12a of the P extending to the head Pa is projected rearward, and a space R for accommodating the air respirators 13 to 13 is formed in the back of the occupant P.

Each of the air respirators 13 is of a well-known backpack type, and includes a cylinder 13a and a backrest portion 13b, and a shoulder / waist belt, a regulator, a hose, a mask, etc., which are not shown. In addition, each air respirator 13
Has the backrest portion 13b in the front and tilts backward as a whole at a predetermined angle to bring the central rear surface of the cylinder 13a into contact with the bracket 14 fixed to a part 12a of the rear wall.
Mounting belt 15 that can be attached and detached with one-touch operation on the upper part of the
Part of the rear wall is fixed to a part 12a of the rear wall via (not shown in detail), and a mounting metal fitting 16 (details not shown) that allows the lower end of the backrest 13b to be detached by one-touch operation. It is fixed to a lower step portion 12b formed by 12a, is detachably installed on the step portion 12b, and is configured to also function as a seat back of the rear seat 11.

Further, in this embodiment, each headrest 17 is attached to the upper step portion 12c formed by the part 12a of the rear wall 12.
Are fixed to the stays 17a, and the headrest Pa of the occupant P is protected by each headrest 17.

In the present embodiment configured as described above, since each air respirator 13 also functions as the seat back of the rear seat 11, the conventional seat back shown in FIG. 3 becomes unnecessary, and the cost is reduced. In addition, the air respirator 13 can be easily attached and detached, and the mounting space conventionally required for seat backs can be eliminated to effectively utilize the space for other uses such as a living space. it can.

Further, since the backrest portion 13b of each air respirator 13 can be leaned directly, each occupant P can wear each air respirator 13 in advance before arriving at the fire scene. Then, each mounting belt 15 and the mounting bracket 16 can be removed by one-touch operation to prepare for an emergency activity.

In addition, in the present embodiment, the headrest 1 is effectively utilized by utilizing the step portion 12c formed above each air respirator 13.
Since 7 is provided, the safety of the occupant P can be improved without impairing the detachability of the air respirator 13.

FIG. 4 schematically shows a front seat portion of a fire engine, in which an air breather 23 is provided on a body step portion 22 on the driver side rear side of a seat cushion 21a in a passenger seat 21 for two persons. Are provided (see FIG. 5).

The air respirator 23 is a well-known backpack type, and includes a cylinder 23a and a backrest portion 23b, and a shoulder / waist belt, a regulator, a hose, a mask, etc., which are not shown. Further, the air respirator 23 is brought into contact with the curved portion 24a formed by the partition beam 24 (which separates the front seat and the rear seat) at the upper rear surface of the cylinder 23a with the backrest portion 23b as the front through the pad 29. Attachment belt 25 that can be detached with one-touch operation (see Fig. 6)
Is fixed to the partition beam 24 via the backrest 23
Mounting bracket 26 that allows you to attach and detach the lower end of b with one-touch operation
It is removably installed on the body step portion 22 through (see FIGS. 5 and 7), and is configured so as to also function as one seat back of the passenger seat 21.

In the present embodiment configured as described above, since the air respirator 23 also functions as one of the seat backs in the passenger seat 21, the seat back is not required in the same portion, and the cost can be reduced. At the same time, the air respirator 23 can be easily attached and detached, and the mounting space conventionally required for the seat back can be eliminated and the space can be effectively used as the mounting space for the air respirator 23.

Also, since the backrest portion 23b of the air respirator 23 can be leaned directly, the passenger in the passenger seat can wear the air respirator 23 before arriving at the fire site, and at the fire site. It is possible to remove the attachment belt 25 by one-touch operation and remove it forward from the attachment metal fitting 26 to prepare for an emergency activity.
