Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
163 words
In a vehicle equipped with at least one inflatable air bag for protecting at least one passenger of the vehicle in case of an accident, wherein an inflation assembly for said bag comprises: a pressurized gas tank having a front portion and at least one branch portion in a continuous configuration extending from said front portion of said pressurized gas tank, said branch portion connecting said front portion to said at least one inflatable air bag, said front portion mounted in the front region of the vehicle and extending transversely of the vehicle longitudinal axis from one side to the opposite side of the vehicle; and at least one automatic valve, said one automatic valve connected between the pressurized gas tank and each associated inflatable air bag, said pressurized gas tank inflating said air bag upon impact during an accident, without the use of separate sensors, due to a sudden increase in pressure within the gas tank which causes said valve to open.
Claim 2
Dependent Claim
163 words
In a vehicle equipped with at least one inflatable air bag for protecting at least one passenger of the vehicle in case of an accident, wherein an inflation assembly for said bag comprises: a pressurized gas tank having a front portion and at least one branch portion in a continuous configuration extending from said front portion of said pressurized gas tank, said branch portion connecting said front portion to said at least one inflatable air bag, said front portion mounted in the front region of the vehicle and extending transversely of the vehicle longitudinal axis from one side to the opposite side of the vehicle; and at least one automatic valve, said one automatic valve connected between the pressurized gas tank and each associated inflatable air bag, said pressurized gas tank inflating said air bag upon impact during an accident, without the use of separate sensors, due to a sudden increase in pressure within the gas tank which causes said valve to open.
