Abstract
Abstract A spring rewound safety belt retraction reel is releasably locked in a belt retracted condition, to relieve the spring rewinding tension on the extended belt, by a swingable latching member which is spring urged into engagement with a reel mounted abutment when the belt is partially or fully withdrawn. In one form the locking abutment is covered by the wound belt and is exposed for locking engagement when the belt is fully withdrawn and in another form the abutment is located on the reel flange and the latching member is held by the wound belt out of locking engagement with the abutment until the belt is at least partially withdrawn. A selectively manipulated member is connected to the locking member to facilitate its release.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A safety belt retractor comprising a reel including a shaft, a belt connected to and windable on said reel shaft, said reel being rotated in a first direction with the withdrawal of said belt and rotatable in a second opposite direction to retract said belt, a windup spring urging said reel to rotate in said second direction, a movable locking member resiliently urged toward engagement with said shaft and restricted against said engagement by the belt wound on said reel, means responsive to said locking member engaging said shaft for releasably locking said reel against rotation in said second direction, and selectively actuated means for releasing said locking means.
Claim 2
Dependent Claim
109 words
A safety belt retractor comprising a reel including a shaft, a belt connected to and windable on said reel shaft, said reel being rotated in a first direction with the withdrawal of said belt and rotatable in a second opposite direction to retract said belt, a windup spring urging said reel to rotate in said second direction, a movable locking member resiliently urged toward engagement with said shaft and restricted against said engagement by the belt wound on said reel, means responsive to said locking member engaging said shaft for releasably locking said reel against rotation in said second direction, and selectively actuated means for releasing said locking means.
Claim 3
Dependent Claim
20 words
The safety belt retractor of claim 1 wherein said locking means releasably locks said reel against rotation in any direction.
Claim 4
Dependent Claim
37 words
The safety belt retractor of claim 1 wherein said locking means comprises means defining a shoulder rotatable with said reel and facing said second direction, said movable locking member being resiliently urged toward engagement with said shoulder.
Claim 5
Dependent Claim
60 words
The safety belt retractor of claim 3 wherein said reel includes a peripheral flange rotatable therewith and having a recess formed in the periphery thereof, an edge of said recess defining said shoulder, and a belt sensing member mounted on said locking member and movable with the movement of said locking member into engagement with said belt on said reel.
Claim 6
Dependent Claim
20 words
The safety belt retractor of claim 3 wherein said release means comprises a finger piece connected to said locking member.
Claim 7
Dependent Claim
119 words
A safety belt retractor comprising a reel including an axial shaft, a belt connected to and windable on said shaft, said reel being rotated in a first direction with the withdrawal of said belt and rotatable in a second opposite direction to retract said belt, a windup spring urging said reel to rotate in said second direction, means defining a shoulder located on and rotatable with said shaft and facing said second direction and being covered by the belt wound on said shaft, releasable locking means including a movable locking member resiliently urged toward engagement with said shoulder and restricted against said engagement by the belt wound on said shaft, and selectively actuated means for releasing said locking means.
Claim 8
Dependent Claim
119 words
A safety belt retractor comprising a reel including an axial shaft, a belt connected to and windable on said shaft, said reel being rotated in a first direction with the withdrawal of said belt and rotatable in a second opposite direction to retract said belt, a windup spring urging said reel to rotate in said second direction, means defining a shoulder located on and rotatable with said shaft and facing said second direction and being covered by the belt wound on said shaft, releasable locking means including a movable locking member resiliently urged toward engagement with said shoulder and restricted against said engagement by the belt wound on said shaft, and selectively actuated means for releasing said locking means.
Claim 9
Dependent Claim
166 words
A safety belt retractor comprising a bracket having a pair of spaced arms, a reel extending between and rotatably supported by said arms, a belt connected to said reel, said reel being rotated in a first direction with the withdrawal of said belt and rotatable in a second opposite direction to retract said belt, a windup spring urging said reel to rotate in said second direction, means defining a shoulder rotatable with said reel and facing said second direction, a windup spring urging said reel to rotate in said second direction, a locking lever having an element proximate a first end thereof movable into and out of engagement with said shoulder and restricted against said engagement by the belt wound on said reel, said lever being mounted on said bracket for rocking about an axis between the ends of said lever, and release means including a push member connected to said lever proximate and end remote from said first end and extending longitudinally from said bracket.
Claim 10
Dependent Claim
166 words
A safety belt retractor comprising a bracket having a pair of spaced arms, a reel extending between and rotatably supported by said arms, a belt connected to said reel, said reel being rotated in a first direction with the withdrawal of said belt and rotatable in a second opposite direction to retract said belt, a windup spring urging said reel to rotate in said second direction, means defining a shoulder rotatable with said reel and facing said second direction, a windup spring urging said reel to rotate in said second direction, a locking lever having an element proximate a first end thereof movable into and out of engagement with said shoulder and restricted against said engagement by the belt wound on said reel, said lever being mounted on said bracket for rocking about an axis between the ends of said lever, and release means including a push member connected to said lever proximate and end remote from said first end and extending longitudinally from said bracket.
