battery 13 is disabled in the collision. In such event,
opening of the fuse 61 prevents the shorted, fired
electro-explosive device from draining a redundant power
supply 20 sufficiently to prevent
same from thereafter firing additional electro-explosive
devices. Should the deceleration level continue to increase
at least to the threshold of the deceleration sensing device
59, the latter closes, applying current from the power output
line 28 through line 41 to a further electro-explosive device
34 causing same to detonate and flow gas through line 52 to
confinement C for further protecting the corresponding vehicle
occupant against the increased deceleration.
After the scope and content of the prior art are
determined, the differences between the prior art and the
claims at issue are to be ascertained. Graham v. John Deere
Co., 383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966).
Based on our analysis and review of Kanazawa and claim 1,

detecting member for detecting a collision of the vehicle; and
