Abstract

An inflatable system includes a first bladder configured to contain gas and a second bladder configured to contain gas. The first bladder includes a top wall, a bottom wall opposite of the top wall, a sidewall extending between and connected to perimeter edges of the top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of the top and bottom walls. The second bladder includes a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls. The bottom wall of the first bladder is secured to the top wall of the second bladder.

First claim

What is claimed is:

1. An inflatable system comprising:
a first bladder configured to contain gas, the first bladder including a top wall, a bottom wall opposite of the top wall, a sidewall extending between and connected to perimeter edges of the top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of the top and bottom walls; and
a second bladder configured to contain gas, the second bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls, wherein the bottom wall of the first bladder is secured to the top wall of the second bladder;
a membrane disposed between the first and second bladders, wherein the bottom wall of the first bladder is one of attached to and formed by a top surface of the membrane and the top wall of the second bladder is one of attached to and formed by a bottom surface of the membrane such that the bottom wall of the first bladder is secured to the top wall of the second bladder through the membrane;
a third bladder configured to contain gas, the third bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls;
a fourth bladder configured to contain gas, the fourth bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls, wherein:
the bottom wall of the third bladder is one of attached to and formed by the top surface of the membrane;
the top wall of the fourth bladder is one of attached to and formed by the bottom surface of the membrane;
when the first and third bladders are inflated, the sidewall of the third bladder abuts the sidewall of the first bladder at a first location along a length of the membrane; and
when the second and fourth bladders are inflated, the sidewall of the fourth bladder abuts the sidewall of the second bladder at a second location along the length of the membrane; and

wherein each of the first, second, third and fourth bladders are inflatable and deflatable independent of one another and the inflatable system is configurable in a first orientation with the third bladder deflated and the fourth bladder inflated and the top wall of the third bladder being at an angle of less than 180 degrees to the top wall of the first bladder and is configurable in a second orientation different that the first orientation with the third bladder inflated and the fourth bladder deflated and the bottom wall of the fourth bladder being at an angle of less than 180 degrees to the bottom wall of the second bladder.

2. The inflatable system of claim 1 wherein the inflatable system is reconfigurable by at least one of inflating the third bladder, deflating the third bladder, and adjusting the tension of the tethers in at least one of the first, second, and third bladders.

3. The inflatable system of claim 1 wherein:
the second location is the same as the first location; and
an interface between the abutting sidewalls of the first and third bladders is disposed above an interface between the abutting sidewalls of the second and fourth bladders.

4. The inflatable system of claim 1 wherein:
the second location is different than the first location; and
the third bladder is disposed above an interface between the abutting sidewalls of the second and fourth bladders.

5. The inflatable system of claim 4 wherein the first, second, third, and fourth bladders are configured to form at least a portion of a vehicle seat cushion, the inflatable system further comprising a panel control module configured to deflate the third bladder such that the second and fourth bladders fold toward one another and around an occupant on the vehicle seat cushion under a weight of the occupant.

6. An inflatable system comprising:
a first bladder configured to contain gas, the first bladder including a top wall, a bottom wall opposite of the top wall, a sidewall extending between and connected to perimeter edges of the top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of the top and bottom walls;
a second bladder configured to contain gas, the second bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls, wherein the second bladder is releasably attached to the first bladder by a first zipper;
wherein when the first and second bladders are inflated, the sidewall of the second bladder abuts the sidewall of the first bladder;
the first zipper releasably attaches the one sidewall of the second bladder to the one sidewall of the first bladder;
a third bladder configured to contain gas, the third bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls,
a fourth bladder configured to contain gas, the fourth bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls, wherein:
the bottom wall of the first bladder is secured to the top wall of the third bladder;
the bottom wall of the second bladder is secured to the top wall of the fourth bladder;
when the third and fourth bladders are inflated, the sidewall of the fourth bladder abuts the sidewall of the third bladder; and
a second zipper that releasably attaches the one sidewall of the fourth bladder to the one sidewall of the third bladder.

7. The inflatable system of claim 6 further comprising:
a first membrane disposed between the first and third bladders, wherein the bottom wall of the first bladder is one of attached to and formed by a top surface of the first membrane and the top wall of the third bladder is one of attached to and formed by a bottom surface of the first membrane; and
a second membrane disposed between the second and fourth bladders, wherein:
the bottom wall of the second bladder is one of attached to and formed by a top surface of the second membrane and the top wall of the fourth bladder is one of attached to and formed by a bottom surface of the second membrane; and
a third zipper that releasably attaches the second membrane to the first membrane.

8. A vehicle seating and cargo system comprising:
a vehicle passenger cabin;
a seat secured within the vehicle passenger cabin and including:
a first bladder configured to contain gas, the first bladder including a top wall, a bottom wall opposite of the top wall, a sidewall extending between and connected to perimeter edges of the top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of the top and bottom walls; and
a second bladder configured to contain gas, the second bladder including a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bott
