## Title
Buoyancy compensator bladder suitable for both back mount and side mount diving

## Abstract

A buoyancy compensator bladder includes an air cell, a connector, a low-pressure inflator (LPI), and at least one over pressure valve. The LPI which inflates and deflates the air cell is positioned on an outer surface of the air cell. As a result, when the fully assembled buoyancy compensator is equipped by a diver, the LPI runs from behind the diver's torso and under their armpit. This results in the inflator head which is part of the LPI to be disposed on the front of the diver's chest during back mount or side mount diving. This structure allows the bladder to be easily used for either back mount or side mount diving. The bladder may further be equipped with auxiliary/non-essential devices such as wight pockets/pouches.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a buoyancy compensator bladder and, more particularly, to a buoyancy compensator bladder that includes a low-pressure inflator suitably positioned for both back mount and side mount diving.
2. Description of the Related Art
Several designs for a buoyancy compensator bladder have been designed in the past. None of them, however, include a buoyancy compensator bladder with a low-pressure inflator (LPI) suitably positioned for both back mount and side mount diving configurations. The LPI which inflates and deflates the air cell is positioned on an outer surface of the air cell. As a result, when the fully assembled buoyancy compensator is equipped by a diver, the LPI runs from behind the diver's torso and under their armpit. This results in the inflator head which is part of the LPI to be disposed on the front of the diver's chest during back mount or side mount diving. This structure allows the bladder to be easily used for either back mount or side mount diving. It is known that divers often use back mount or side mount configurations when diving. Additionally, most buoyancy compensator bladders are currently designed to work exclusively for either back mount or side mount diving. Therefore, there is a need for a buoyancy compensator bladder that allows for the LPI to run under the diver's armpit for use of both back mount and side mount diving. This allows the present invention to adapt to a user's preferred method of diving.
Applicant believes that a related reference corresponds to U.S. Pat. No. 3,877,098 issued for a buoyancy pillow for a free diver that is attached to the ventral side of diver's trunk by shoulder, waist, and crotch straps. Applicant believes that another related reference corresponds to U.S. Pat. No. 5,662,433 issued for a combination spider and buoyancy compensator having a chest portion which include stretchable material to support the breasts of a diver. However, the cited references differ from the present invention because they fail to disclose a buoyancy compensator bladder with an LPI suitably positioned to run under the diver's armpit to allow for both back mount and side mount diving. The location of the LPI mounted provides a flexible configuration that adapts to a user's need based on preference when performing a diving task.
Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
SUMMARY OF THE INVENTION
It is one of the objects of the present invention to provide a buoyancy compensator bladder with an LPI that runs under diver's armpit when the bladder is used for back mount diving.
It is another object of the present invention to provide a buoyancy compensator bladder with an LPI that runs under the diver's armpit when the bladder is used for side mount diving.
It is another object of this invention to provide a buoyancy compensator bladder that does not need to be repositioned. Additionally, neither the bladder nor the buoyancy compensator has to be reconfigured when switching from back mount to side mount diving.
It is still another object of the present invention to provide a buoyancy compensator bladder that is versatile and easy to use.
It is yet another object of this invention to provide such a device that is inexpensive to implement and maintain while retaining its effectiveness.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

As a result, all the assemblies are engaged when the present system is assembled. It should be understood that different embodiments of the present invention may not include the cylinder adapter member 62.
FIGS. 6-8 depict the present system engaged in the rear mount configuration. It can be observed that cam bands 68 are used to secure the cylinder to the rear of the air cell 22 by means of the cylinder adapter assembly 60. However, it should be understood that the present invention could be configured with one cam band 68. The LPI 26 comfortably runs under the armpit of the user and the inflator head 26A comfortably sits at the front end of the user. FIGS. 9-11 depict the present system engaged in a side mount configuration. It can be observed that the cylinder is connected to two D-rings 45 located on the harness 44 with one D-ring 45 on the shoulder strap, and another D-ring 45 on the waist strap by means of two swivel rings with a single end bolt snap. The figures depict one cylinder mounted onto the system. However, it should be understood that two cylinders may be utilized for the side mount configuration. The LPI 26 then comfortably runs under the armpit of the user and the inflator head 26A sits at the front end of the user similar to the configuration of the rear mount diving. The present invention advantageously allows for a diver to use their preferred diving configuration without the need to change equipment to suit rear mount or side mount diving.
The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
