Abstract
Abstract The following specification sets forth a conformable buoyancy compensator that conforms to a user's body in a uniform manner during use. The buoyancy compensator incorporates an interior bladder having a plurality of heat sealed pleats or insets around the shoulder area in order to provide conformity of the buoyancy compensator to a user's body. The bladder further comprises interior reinforced gussets that retain the conformation of the bladder in a plurality of air channels or pockets that conform to the frontal areas of a user's body. The arm openings are free and open for a user to extend one's arms. Between the front and back portions of the air channels are a plurality of side panels that can be made of spandex, elastic, or can be configured of suitable strapping. The buoyancy compensator has vents. Vented pockets are provided for the receipt of a second stage regulator therein, as well as providing for other specific storage of items used by a diver. The combination of notches, pleats, and insets that have been heat set into the shoulder portion in combination with the heat set reinforced gussets within the bladder in the frontal and rear portion of the buoyancy compensator allow for a conformable configuration that conforms to the body. The foregoing configuration eliminates bulges and undue expansion of the buoyancy compensator into an extended relationship as is known in the prior art.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A buoyancy compensator for providing buoyancy trim to an underwater diver comprising: a first outer cover conforming to a user's chest area and back area and having means for attaching a diver's backpack thereto; a bladder internally of said outer cover conforming generally to the front and rear portion of said buoyancy compensator having a chamber therein that has been divided by connecting the front and back walls of said chamber into a plurality of cummunicating pockets divided by a rib adhered to said front and back walls extending within at least a portion of the front of said buoyancy compensator and the rear of said buoyancy compensator; pleats within the shoulder region of said buoyancy compensator formed within said bladder to allow folding of said bladder in conformation to a user's shoulder; said bladder is formed of a plastic material; and, said rib is heat set into said plastic material with reinforcing enlargements at the end of said heat set to prevent tearing of said rib along said heat set.
Claim 2
Dependent Claim
171 words
A buoyancy compensator for providing buoyancy trim to an underwater diver comprising: a first outer cover conforming to a user's chest area and back area and having means for attaching a diver's backpack thereto; a bladder internally of said outer cover conforming generally to the front and rear portion of said buoyancy compensator having a chamber therein that has been divided by connecting the front and back walls of said chamber into a plurality of cummunicating pockets divided by a rib adhered to said front and back walls extending within at least a portion of the front of said buoyancy compensator and the rear of said buoyancy compensator; pleats within the shoulder region of said buoyancy compensator formed within said bladder to allow folding of said bladder in conformation to a user's shoulder; said bladder is formed of a plastic material; and, said rib is heat set into said plastic material with reinforcing enlargements at the end of said heat set to prevent tearing of said rib along said heat set.
Claim 3
Dependent Claim
40 words
The buoyancy compensator as claimed in claim 1 further comprising: said pleats of said buoyancy compensator being heatset into said bladder in the form of a linear seal terminating in an enlarged portion to prevent tearing along said linear seal.
Claim 4
Dependent Claim
28 words
The buoyancy compensator as claimed in claim 2 further comprising: inflation means having a mouthpiece attached thereto and connected to said buoyancy compensator bladder through said outer material.
Claim 5
Dependent Claim
23 words
The buoyancy compensator as claimed in claim 2 further comprising: at least one pocket on said buoyancy compensator in the frontal area thereof.
Claim 6
Dependent Claim
31 words
The buoyancy compensator as claimed in claim 4 further comprising: drains within the base of said buoyancy compensator in the outer material in the form of an open elastic mesh cloth.
Claim 7
Dependent Claim
74 words
The buoyancy compensator as claimed in claim 4 wherein: said pocket has a flap with means for attaching said flap to the frontal portion thereof; and, at least one side wall having a lesser height dimension than the frontal portion so that a second stage regulator can be implaced within said pocket and the hose therefrom allowed to extend from said pocket when said flap is covering said hose and said second stage regulator.
Claim 8
Dependent Claim
216 words
A buoyancy compensator having the capability of increasing or decreasing relative buoyancy of an underwater diver dependent upon the air therein adaptively formed with a neck portion forming a yoke around a user's neck and a vest portion on either side of one's chest with a rear portion adapted for placement at least in part on each side of a backpack for a diver wherein the improvement comprises: a frontal bladder portion having at least two communicating chambers divided at least in part by an internal spanning member formed as a portion of the bladder connecting the front and back walls of said bladder to form said plurality of chambers, means to receive a backpack for diving tanks on the rear portion of said backpack; covering means overlying said bladder to control the expansion thereof; a plurality of chambers formed in the rear of said buoyancy compensator bladder freely communicable with said front chambers, wherein said bladder is formed from a plastic material which has been heat set to provide at least in part said spanning member; heat set pleats around the shoulder portion thereof; and said pleats being formed as linear heat set pleats terminating in an expanded heat set area in order to crimp and retain the buoyancy compensator shoulder configuration around said shoulder.
Claim 9
Dependent Claim
216 words
A buoyancy compensator having the capability of increasing or decreasing relative buoyancy of an underwater diver dependent upon the air therein adaptively formed with a neck portion forming a yoke around a user's neck and a vest portion on either side of one's chest with a rear portion adapted for placement at least in part on each side of a backpack for a diver wherein the improvement comprises: a frontal bladder portion having at least two communicating chambers divided at least in part by an internal spanning member formed as a portion of the bladder connecting the front and back walls of said bladder to form said plurality of chambers, means to receive a backpack for diving tanks on the rear portion of said backpack; covering means overlying said bladder to control the expansion thereof; a plurality of chambers formed in the rear of said buoyancy compensator bladder freely communicable with said front chambers, wherein said bladder is formed from a plastic material which has been heat set to provide at least in part said spanning member; heat set pleats around the shoulder portion thereof; and said pleats being formed as linear heat set pleats terminating in an expanded heat set area in order to crimp and retain the buoyancy compensator shoulder configuration around said shoulder.
