Abstract
An assembly includes at least one control fluid line, at least one bladder fluid line connectable to at least one bladder; and at least one pinch valve associated with the at least one bladder fluid line. The at least one pinch valve is selectively moveable to a bladder inflation position based on a pressure in the at least one control fluid line.
Claims20
An assembly comprising:
- at least one control fluid line;
- at least one bladder fluid line connectable to at least one bladder;
- and
- at least one pinch valve associated with the at least one bladder fluid line, the at least one pinch valve selectively moveable to a bladder inflation position based on a pressure in the at least one control fluid line.
1 more element
An assembly comprising:
- at least one seat component;
- a plurality of bladder fluid lines connectable to a plurality of bladders associated with the at least one seat component, wherein each bladder is movable between an inflation position and a deflation position;
- a plurality of branches associated with each bladder fluid line, wherein each branch fluidly connects one bladder of the plurality of bladders to a bladder fluid line of the plurality of bladder fluid lines;
- a plurality of control fluid lines associated with the plurality of bladder fluid lines;
- and
- a plurality of pinch valves, wherein each pinch valve controls a flow of fluid in one of the branches based on a pressure in an associated control fluid line of the plurality of control fluid lines.
3 more elements
A method comprising:
- connecting at least one bladder fluid line to at least one bladder via a branch;
- associating a pinch valve with each branch;
- and
- adjusting pressure within a control fluid line to open the at least one pinch valve and inflate the at least one bladder.
