Abstract
Abstract A motor vehicle safety belt system includes a switch actuated by the engagement of the driver''s safety belt and a network for starting the vehicle engine upon the acutation of the switch. The passenger seats are provided with switches actuated by the occupation of the respective seats and switches actuated by the engagement of the respective safety belts, a signal being given if any seat is occupied and the respective seat belt disengaged. Each of the belts is provided with a spring wound take up reel which is pawl and sprocket braked against belt withdrawal, the brake being released upon occupation of a corresponding seat and engaged upon the actuation of a vehicle mounted inertia switch. The belts are of the waist and shoulder types, the shoulder belt having overlapping sections which are joined along longitudinally spaced transverse lines of stitching which are rupturable under progressively larger loads to extend the shoulder belts by successive increments under such loads.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
172 words
A motor vehicle including a drive engine comprising means for starting said drive engine, a first seat in said vehicle, a safety belt associated with said seat and movable between an engaged and a disengaged condition, a spring retracted take-up reel upon which said safety belt is wound and urged toward a retracted position, a first switch transferable between an actuated and a deactuated position in response to the engaged and disengaged conditions respectively of said belt, a second switch transferable between an actuated and deactuated position in response to said belt being withdrawn from said reel more and less respectively than a predetermined amount, a third switch transferable between an actuated and a reactivated position in response to the rotation of said engine being below and exceeding a predetermined value respectively and means responsive to all of said switches being simultaneously in their actuated positions for enabling said engine starting means and responsive to at least one of said switches being in its deactuated position for disabling said engine starting means.
Claim 2
Dependent Claim
172 words
A motor vehicle including a drive engine comprising means for starting said drive engine, a first seat in said vehicle, a safety belt associated with said seat and movable between an engaged and a disengaged condition, a spring retracted take-up reel upon which said safety belt is wound and urged toward a retracted position, a first switch transferable between an actuated and a deactuated position in response to the engaged and disengaged conditions respectively of said belt, a second switch transferable between an actuated and deactuated position in response to said belt being withdrawn from said reel more and less respectively than a predetermined amount, a third switch transferable between an actuated and a reactivated position in response to the rotation of said engine being below and exceeding a predetermined value respectively and means responsive to all of said switches being simultaneously in their actuated positions for enabling said engine starting means and responsive to at least one of said switches being in its deactuated position for disabling said engine starting means.
Claim 3
Dependent Claim
43 words
The motor vehicle of claim 1 wherein said engine starting means comprises an engine starter relay and circuit means for connecting said relay to a source of current and being in an open condition when at least one of said switches is deactuated.
Claim 4
Dependent Claim
67 words
The motor vehicle of claim 1 wherein each of said first and second switches is closed and opened when in its actuated and deactuated positions respectively and said third switch is opened and closed when in its actuated and deactuated positions respectively and said engine starting means comprises an engine starter relay and means for connecting said relay and switches in series to a source of current.
Claim 5
Dependent Claim
33 words
The motor vehicle of claim 1 wherein said safety belt includes a pair of separably engageable buckle elements, said first switch being transfered to an actuated position upon engagement of said buckle elements.
Claim 6
Dependent Claim
51 words
The motor vehicle of claim 1 wherein said safety belt terminates in a tongue member and including a buckle member engageable with said tongue member in a releasably locked position, said first switch being mounted on said buckle and actuated in response to the buckle engaged conditIon of said tongue member.
Claim 7
Dependent Claim
51 words
The motor vehicle of claim 1 including a second seat, a second safety belt associated with said second seat and movable between engaged and disengaged positions, and means for providing a signal in response to the concurrent occupation of said second seat and the disengaged position of said second safety belt.
Claim 8
Dependent Claim
29 words
The motor vehicle of claim 1 comprising means for providing a signal in response to the concurrent occupation of said seat and the disengaged position of said safety belt.
Claim 9
Dependent Claim
77 words
The motor vehicle of claim 7 wherein said signal means comprises a first switch transferable to first and second states in response to the downward force on said seat being respectively more or less than a predetermined value, a second switch transferable to first and second states in response to the disengage and engage positions respectively of said safety belt, said signal means being actuated when said first and second switches are both in their first state.
Claim 10
Dependent Claim
63 words
The motor vehicle of claim 7 comprising a spring retracted take-up reel upon which said belt is wound, and a switch positioned proximate to said reel and actuated in response to the rotation of said reel to a position corresponding to the withdrawal of said safety belt to its normally engage position, said signal means being responsive to the actuation of said switch.
Claim 11
Dependent Claim
43 words
The motor vehicle of claim 7 comprising a spring retracted take-up reel upon which said belt is wound, reel braking means normally restricting the withdrawal of said safety belt, and means responsive to the occupation of said seat for releasing said braking means.
Claim 12
Dependent Claim
31 words
The motor vehicle of claim 10 comprising a inertia switch, and means responsive to the actuation of said inertia switch for engaging said brake independently of the occupation of said seat.
Claim 13
Dependent Claim
15 words
The motor vehicle of claim 1 wherein said second switch is mounted on said reel.
