Abstract
Abstract An automobile seat belt system ensures that the belts of occupied seats are properly worn. The system compares the amount of belt withdrawn from an inertia reel with the position of the seat and the angle of the seat back, and if the amount of belt is outside the normal range or the angle of the belt is abnormal in respect to the driver''s or any occupied passenger seat, a warning device is actuated when the vehicle speed exceeds a predetermined low speed. The system may also lock any fastened seat belts when the transmission is placed in gear and when the vehicle speed exceeds the predetermined low speed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
In an automobile having forwardly and rearwardly adjustable front seats and reel wound seat belts, a seat belt safety system coupled to the ignition system of the automobile, comprising the combination of, a. means for each seat connected to and actuated by rotation of each reel for sensing the amount of belt withdrawn from the reel, b. means for each seat connected to and actuated by movement of said seat for sensing the fore and aft position of the seat, c. an electrical supply line including two switches in series, one switch being operated by the belt withdrawal and position sensing means of one of said seats, the other switch being operated by the belt withdrawal and position sensing means of the other of said seats, d. a first relay in said supply line which, when said two switches are both closed, causes the iGnition system to be energized.
Claim 2
Dependent Claim
149 words

Claim 3
Dependent Claim
48 words
The combination of claim 1 including, a. an automobile speed sensing means, b. a second relay, said speed sensing means coupled to and operating said second relay, c. said second relay bypassing said first relay to thereby energize the ignition system at automobile speeds below a predetermined amount.
Claim 4
Dependent Claim
49 words
The combination of claim 2 including, a. a third relay actuated by said second relay when the speed is above said predetermined speed, said third relay actuating a warning signal should a seat belt become unfastened, said third relay locking in once it becomes energized by said second relay.
Claim 5
Dependent Claim
56 words
The combination of claim 2 including, a. a third relay, said third relay actuated by said second relay when the speed is above said predetermined speed, said third relay coupled to said first relay and locking said first relay in, to thereby prevent loss of ignition should a fault occur after said predetermined speed is attained.
