Control unit with an air pressure detector for a vehicle passenger protection system
First Claim
1. In combination with a vehicle having a body with a side, a control assembly for a passenger protection system of the vehicle which is to be tripped upon the occurrence of a traffic accident with a side impact, the control assembly comprising:
- at least one detector adapted to detect a pressure rise in a hollow body, said at least one detector being mounted in a largely enclosed side portion of the side of the vehicle body defining the hollow body; and
a control unit connected to and receiving signals from said at least one detector, said control unit evaluating a sudden and largely adiabatic air pressure rise detected by said detector upon a side impact collision.

Abstract
A control assembly for a passenger protection system of a vehicle which is tripped upon the occurrence of a side impact traffic accident. The control assembly has at least one detector adapted to detect a pressure rise in a hollow body. The at least one detector is mounted in a largely enclosed side portion on the side of the vehicle body defining a hollow body such as a door. A control unit is connected to and receives signals from the at least one detector. The control unit evaluates a sudden and largely adiabatic air pressure rise detected by the detector upon a side impact collision and determines whether to actuate a passenger protection system such as an air bag.

16. A control system for tripping a vehicle passenger protection system upon a side collision, comprising:
-
at least one air pressure detector as a sensor in a largely enclosed side portion of the vehicle defining a hollow body; and a control unit evaluating a sudden pressure rise in ambient air about said sensor occurring in a side collision.
