Abstract
Abstract A coupling arrangement for connecting the outboard end of a passive seat or shoulder belt to a fixed or movable anchor on the vehicle door or the body near the door comprises a plate connected to the anchor, a plate connected to the belt, a pin on one of the plates, a key-type hole on the other plate and a resilient retainer which retains the pin in a smaller part of the slot and prevents manual release of the coupling.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
In a passive vehicle occupant restraint belt system which includes a belt leading from a retractor located inboard of the seat to an anchor outboard of the seat, a coupling arrangement for connecting the belt to the anchor comprising a first plate member connected to the anchor, a second plate member connected to the belt, releasable coupling means for coupling the first and second plates and including a pin projecting from one of the plates and having a head portion and a shank portion that is smaller in at least one dimension than the head portion and a key-type hole in the other plate that includes a larger portion through which the head portion can pass and a smaller portion which accepts the shank portion but through which the head portion cannot pass, and retainer means for blocking the pin in the smaller portion of the hole and preventing manual release of the coupling means including a substantially flat spring member affixed substantially flatwise to one of the first and second plate members having a portion engageable with a portion of the other of the first and second plate members when the pin is accepted in the smaller portion of the hole.
Claim 2
Dependent Claim
202 words
In a passive vehicle occupant restraint belt system which includes a belt leading from a retractor located inboard of the seat to an anchor outboard of the seat, a coupling arrangement for connecting the belt to the anchor comprising a first plate member connected to the anchor, a second plate member connected to the belt, releasable coupling means for coupling the first and second plates and including a pin projecting from one of the plates and having a head portion and a shank portion that is smaller in at least one dimension than the head portion and a key-type hole in the other plate that includes a larger portion through which the head portion can pass and a smaller portion which accepts the shank portion but through which the head portion cannot pass, and retainer means for blocking the pin in the smaller portion of the hole and preventing manual release of the coupling means including a substantially flat spring member affixed substantially flatwise to one of the first and second plate members having a portion engageable with a portion of the other of the first and second plate members when the pin is accepted in the smaller portion of the hole.
Claim 3
Dependent Claim
61 words
A coupling according to claim 1 wherein the retainer means is a leaf spring affixed to one of the plates which normally resides in a position in which a portion thereof blocks movement of one plate relative to the other away from a position in which the shank portion of the pin is located in the smaller portion of the hole.
Claim 4
Dependent Claim
49 words
A coupling according to claim 2 wherein the leaf spring is on the plate which has the pin and includes a pair of resiliently deflectable tangs which engage an edge of the other plate to prevent such movement but which deflect to enable the plates to be coupled initially.
Claim 5
Dependent Claim
59 words
A coupling according to claim 2 wherein the leaf spring is on the plate which has the hole and includes a portion which normally overlies at least part of the larger portion of the hole to prevent such plate movement but which resiliently deflects for acceptance of the pin through such larger portion upon initial coupling of the plates.
Claim 6
Dependent Claim
31 words
A coupling according to claim 4 wherein the plate fastened to the belt is pivotable about the axis of the pin for self-positioning of the belt to fit the user properly.
Claim 7
Dependent Claim
44 words
A coupling according to claim 5 and further comprising means for limiting the amount of pivotal movement of the plate on the belt including a projection on one of the plates and an arcuate guide slot on the other plate which receives the projection.
Claim 8
Dependent Claim
58 words
A coupling according to claim 6 wherein the leaf spring includes a portion that is received and held in place between segments of a loop on the end portion of the belt by which the belt is joined to the plate, whereby any tendency for the belt to twist where it is joined to the plate is prevented.
