Abstract
Abstract A vehicle safety belt system includes a pair of belt sections, one carrying a buckle and the other carrying a belt retracting reel device provided with a tongue releasably engageable by the buckle. The reel device includes a spring biased belt retracting reel having a ratchet wheel rotatable with the reel and a pawl movable into locking engagement with the ratchet wheel to prevent withdrawal of the belt from the reel. The pawl carries an actuating member which is acted on by the buckle or an element carried by the buckle to advance the pawl to a reel locking position when the buckle and tongue are coupled.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
A vehicle safety belt mechanism comprising a pair of separable first and second coupling members movable between relatively coupled and uncoupled positions, a retractable belt reel device connected to said first coupling member and including a spring biased belt retracting reel and a belt connected to said reel and withdrawable from and normally retracted by said reel and locking means mounted on said first coupling member and separate from said second coupling member and alternatively movable between a first position locking said belt against withdrawal from said reel and a second position releasing said belt and normally urged to said second position and means responsive to the coupled position of said coupling members and actuated by said second coupling member for transferring said locking means to said first position.
Claim 2
Dependent Claim
129 words
A vehicle safety belt mechanism comprising a pair of separable first and second coupling members movable between relatively coupled and uncoupled positions, a retractable belt reel device connected to said first coupling member and including a spring biased belt retracting reel and a belt connected to said reel and withdrawable from and normally retracted by said reel and locking means mounted on said first coupling member and separate from said second coupling member and alternatively movable between a first position locking said belt against withdrawal from said reel and a second position releasing said belt and normally urged to said second position and means responsive to the coupled position of said coupling members and actuated by said second coupling member for transferring said locking means to said first position.
Claim 3
Dependent Claim
27 words
The mechanism of claim 1 wherein said reel device comprises a bracket member rotatably supporting said reel and said first coupling member is connected to said bracket.
Claim 4
Dependent Claim
70 words
The mechanism of claim 2 wherein said locking means comprises a ratchet wheel rotatable with said reel and a pawl member movable between a first locking position engaging said ratchet wheel and a second release position out of engagement with said ratchet wheel and spring biased to said second position, said pawl member being urged to said first locking position by said second coupling member advancing to its coupled position.
Claim 5
Dependent Claim
53 words
The mechanism of claim 3 wherein said coupling responsive transfer means includes an actuating member connected to and moveable with said pawl member and being engageable and maintained by said second coupling member when engaged by said first coupling member in a position in which said pawl member and ratchet are in engagement.
Claim 6
Dependent Claim
69 words
The mechanism of claim 3 including a cross piece rockably supported by said bracket and carrying said pawl member for rocking therewith into and out of engagement with said ratchet wheel and said transfer means comprising an actuating member supported by and rockable with said cross piece and motivated by the engagement of said coupling members to move and maintain said pawl member in engagement with said ratchet wheel.
Claim 7
Dependent Claim
41 words
The mechanism of claim 5 wherein said second coupling member comprises a buckle and said first coupling member comprises a tongue releasably engaging said buckle, a part of said buckle engaging said actuating member when said buckle and tongue are intercoupled.
Claim 8
Dependent Claim
101 words
Belt take-up adjusting device in safety belt buckle including a buckle body and a tongue, comprising a take-up spring, a shaft, a ratchet, a pawl and the like these of which are provided around the rear end place of said tongue, characterized in that motivating of buckle coupling makes a projection of buckle body and the like push the claw of said pawl provided on the tongue so as to have said claw engage with said ratchet to prevent extending of the belt, so that the belt length fitted on the occupant body can be determined on belt fastening situation naturally.
Claim 9
Dependent Claim
101 words
Belt take-up adjusting device in safety belt buckle including a buckle body and a tongue, comprising a take-up spring, a shaft, a ratchet, a pawl and the like these of which are provided around the rear end place of said tongue, characterized in that motivating of buckle coupling makes a projection of buckle body and the like push the claw of said pawl provided on the tongue so as to have said claw engage with said ratchet to prevent extending of the belt, so that the belt length fitted on the occupant body can be determined on belt fastening situation naturally.
