Abstract
Abstract A mechanism for automatically applying a safety belt to a seat occupant includes a forwardly open arcuate case extending rearwardly of the seat and slideably housing a pair of radially offset quadrant arcuate transfer arms. A gear reduction motor driven, longitudinally grooved drive roller is housed below the seat and opposite sides of the roll are engaged by helical wound flexible cables, the ends of each of which is attached to the proximal ends of respective transfer arms and are guided to the arm proximal end from its front and rear, so that forward rotation of the drive roll advances the arm distal ends forwardly and toward each other, and reverse rotation of the drive roll retracts the arms into the case. A collar is mounted on the distal end of one arm, and slideably engages a waist belt extending from a retractor reel. In one form, a similar collar is mounted on the other arm and engages an opposite belt extending from a retractor, the belts carrying mating buckle members. In another form, the other transfer arm carries a transfer member which, in the transfer member advanced conditions engages a coupling member mounted on the end of the belt and draws it into engagement with a mating coupling member on the other side of the seat, with the retraction of the transfer arms.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
259 words
A mechanism for automatically applying restraint to the occupant of a seat, including a seat portion and a back portion comprising a first belt, first connecting means, including a spring biased belt retractor connecting said belt proximate a first side of said seat, a first coupling member located on said first belt proximate the free end thereof, a second coupling member releasably engageable with said first coupling member, second connecting means connecting said second coupling member proximate a second side of said seat opposite to said first side, a first arcuate transfer arm, first guide means supporting said first transfer arm for movement along the arcuate length of said first transfer arm between a retracted position with the distal end of said transfer arm proximate the rear of said seat portion first side and a position toward said seat second side, a first transfer member mounted on said first transfer arm distal end portion and engaging said first belt to advance the free end thereof with the advance of said first transfer arm and means for advancing said first transfer arm, including a drive wheel, a motor drive coupled to said drive wheel, a first elongated flexible member connected at a first end to the proximate end portion of said transfer arm and engaged and driven by said drive wheel, and guide means leading said elongated member from said drive wheel to said first transfer arm proximal end along a path through a point forward of said proximal end when said transfer arm is rearward of its advanced position.
Claim 2
Dependent Claim
259 words
A mechanism for automatically applying restraint to the occupant of a seat, including a seat portion and a back portion comprising a first belt, first connecting means, including a spring biased belt retractor connecting said belt proximate a first side of said seat, a first coupling member located on said first belt proximate the free end thereof, a second coupling member releasably engageable with said first coupling member, second connecting means connecting said second coupling member proximate a second side of said seat opposite to said first side, a first arcuate transfer arm, first guide means supporting said first transfer arm for movement along the arcuate length of said first transfer arm between a retracted position with the distal end of said transfer arm proximate the rear of said seat portion first side and a position toward said seat second side, a first transfer member mounted on said first transfer arm distal end portion and engaging said first belt to advance the free end thereof with the advance of said first transfer arm and means for advancing said first transfer arm, including a drive wheel, a motor drive coupled to said drive wheel, a first elongated flexible member connected at a first end to the proximate end portion of said transfer arm and engaged and driven by said drive wheel, and guide means leading said elongated member from said drive wheel to said first transfer arm proximal end along a path through a point forward of said proximal end when said transfer arm is rearward of its advanced position.
Claim 3
Dependent Claim
63 words
The mechanism of claim 1 wherein said flexible member includes a second end opposite its first end connected to said first transfer arm proximal portion and guide means leading said flexible member between said second end and said drive wheel along a path through a point rearward of said transfer arm proximal portion when said transfer arm is forward of its retracted position.
Claim 4
Dependent Claim
163 words
The mechanism of claim 2 including a second arcuate transfer arm, second guide means supporting said second arcuate arm for movement between a retracted position with the distal end of said second transfer arm proximate the rear of said seat portion second side and an advanced position proximate to the distal end of the advanced first transfer arm, a second transfer member mounted on the distal end of said second transfer arm, a second felxible elongated member engaging said drive wheel and having opposite first and second ends connected to the distal portion of said second transfer arm, guide means leading the first and second ends of said second flexible member along paths traversing points between said drive wheel and the distal end of said second transfer arm when respectively, forwardly of said distal end, when said second transfer arm is rearwardly of its advanced position and rearwardly of said distal end when said second transfer arm is forwardly of its retracted position.
Claim 5
Dependent Claim
43 words
The mechanism of claim 3 wherein said flexible members comprise transversely ridged flexible cables, and said drive wheel comprises a roll provided with longitudinal recesses engageable with said cable ridges, said first and second flexible cables engaging opposite faces of said drive roll.
Claim 6
Dependent Claim
35 words
The mechanism of claim 3 wherein said second transfer member includes means releasably retaining said first coupling member in response to the engagement thereof consequent to the advance of said first and second transfer arms.
Claim 7
Dependent Claim
47 words
The mechanism of claim 5 wherein said second transfer member is movable with the retraction of said second transfer arm to the proximity of said second coupling member, and said second coupling member releasably engages said first coupling member with the retraction of said second transfer arm.
Claim 8
Dependent Claim
78 words
The mechanism of claim 3 wherein said second connecting means comprises a second spring biased belt retractor and a second belt extending from said second retractor and having said second coupling member positioned at the free end of said belt, said second transfer member engaging said second belt to advance said second belt and second coupling member with the advance of said second transfer arm, the advance of said transfer arms bringing said coupling members into mutual engagement.
Claim 9
Dependent Claim
43 words
The mechanism of claim 3 including a semi-circular tubular case slideably housing said transfer arms and located rearwardly of said seat portion and having forwardly directed openings, and said motor and drive wheel are disposed below the top face of said seat portion.
Claim 10
Dependent Claim
97 words
The mechanism of claim 1 wherein said seat is located in a vehicle having a door and comprising a motor control network including a first switch actuated in response to the closing of said door, a second switch actuated in response to the occupation of said seat and means responsive to the actuation of said first and second switches to energize said motor to rotate in a forward direction to advance said transfer arm, and upon said transfer arm reaching its advanced position energizing said motor to rotate in a reverse direction to retract said transfer arm.
