Abstract
An apparatus (10) includes an inflatable vehicle occupant protection device (14), a source (16) of inflation fluid, and a valve (20) in an inflation fluid flow path extending from the source (16) to the protection device (14) through the valve (20). The valve (20) is actuatable to regulate a flow of inflation fluid through the valve (20) so as to vary rates at which inflation fluid pressure increases in the protection device (14). A controller (22) has a memory location (29) storing predetermined modes of actuation for the valve (20). The predetermined modes of actuation include modes that correspond to predetermined curves (A-E) of inflation fluid pressure versus time. The controller (22) responds to one or more crash conditions by selecting one of the predetermined modes of actuation and by actuating the valve (20) in the selected mode.
