Abstract

Abstract In an electronic device, in particular a piece of safety equipment for vehicle occupants, a switching element (13) which characterizes the operational position of an insertable seat belt is connected in parallel with a firing element (10, 11). The switching element (13) has a break contact which is broken when the seat belt is activated correctly.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 108 words
An electronic device comprising a piece of safety equipment for vehicular occupants, having an output stage (32a, 32b, 32c) which comprises a firing element (10, 11), having an insertable seat belt with a fastening device comprising a belt lock that is fastened by inserting a portion of said seat belt in said belt lock, said seat belt having an operational position which is indicative of whether or not said seat belt is correctly inserted into said belt lock, and having a switching element (13) which characterizes the operational position of said seat belt, wherein said switching element (13) is connected in parallel with said firing element (10, 11).
Claim 2
Dependent Claim 108 words
An electronic device comprising a piece of safety equipment for vehicular occupants, having an output stage (32a, 32b, 32c) which comprises a firing element (10, 11), having an insertable seat belt with a fastening device comprising a belt lock that is fastened by inserting a portion of said seat belt in said belt lock, said seat belt having an operational position which is indicative of whether or not said seat belt is correctly inserted into said belt lock, and having a switching element (13) which characterizes the operational position of said seat belt, wherein said switching element (13) is connected in parallel with said firing element (10, 11).
