<p>A safety system for vehicle driver restraint of the type using a collapsed inflatable confinement mounted on the steering column. The confinement is inflated by a collision sensor-actuated explosive charge which activates a fluid pressure source in one embodiment and fluid is discharged to the confinement through a diffuser disposed centrally and annularly about the reservoir. The annular fluid source is nonrotatably attached to the steering column mast jacket and a rotary fluid pressure seal is provided between the diffuser and the steering column mast jacket. In one embodiment of the invention, the fluid pressure supply is a solid propellant gas generator nonrotatably mounted to the steering column mast jacket. In another embodiment, the fluid pressure source is a toroidally shaped reservoir containing fluid stored under pressure.</p> |
