Personal flotation device having selectively inflatable bladders

摘要

An improved structure for a personal flotation device that is relatively comfortable to wear when not in use includes a primary bladder that is shaped to extend about a waist of a user. The personal flotation device also includes a secondary bladder that is in fluid communication with the primary bladder and is shaped to extend upwardly from the waist across a stomach of the user. Lastly, the personal flotation device includes a tertiary bladder that is in fluid communication with the secondary bladder and is shaped to is adapted to across the front of a chest of the user.

1. A personal flotation device comprising:
a pouch; a primary bladder that, in a deflated condition, is disposed within the pouch and, in an inflated condition, is generally annular in shape such that it can be supported on a waist of a user; a secondary bladder that, in a deflated condition, is disposed within the pouch and, in an inflated condition, is generally shaped as a flat panel that extends from the primary bladder such that it can extend across a stomach of the user, the secondary bladder being in fluid communication with the primary bladder; and a tertiary bladder that, in a deflated condition, is disposed within the pouch and, in an inflated condition, is generally shaped as a flat panel that extends from the secondary bladder such that it can extend across a chest of the user, the tertiary bladder being in fluid communication with the secondary bladder.
