Abstract
Abstract In a passive restraint seatbelt assembly, a first belt, attached to the interior of the vehicle through an inertia sensitive locking retractor reel, and a fixed length slideable belt are joined by a snubbing slip ring which allows free sliding of the slideable belt therethrough in normal conditions but frictionally restrains the slideable belt in emergency situations. The snubbing slip ring is formed with a snubbing bar slideable within a housing by a reverse bend portion of a looped end of the first belt. During tension of the belts, the reverse bend tends to straighten out forcing the snubbing bar against the slideable belt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A passive restraint seatbelt assembly having an adjustable length belt linked at one end to a vehicle and having a folded loop at its free end, a fixed length slideable belt linked at each end to a vehicle, and a snubbing slip ring through which said folded loop is threaded and through which said slideable belt is threaded for sliding therethrough; said snubbing slip ring comprising: a housing having upper and lower slot means; a snubbing bar disposed in said housing for movement between a release portion whereat said slideable belt slides freely through said upper and lower slot means, and a snubbing position whereat said snubbing bar abuts and frictionally restrains said slideable belt, said folded loop folding along said upper and lower slot means and along a portion of said snubbing bar which is disposed behind said upper and lower slot means in said release position so that tension on said adjustable length belt straightens that folded loop between said upper and lower slot means and pushes said snubbing bar forward into said snubbing position.
Claim 2
Dependent Claim
177 words
A passive restraint seatbelt assembly having an adjustable length belt linked at one end to a vehicle and having a folded loop at its free end, a fixed length slideable belt linked at each end to a vehicle, and a snubbing slip ring through which said folded loop is threaded and through which said slideable belt is threaded for sliding therethrough; said snubbing slip ring comprising: a housing having upper and lower slot means; a snubbing bar disposed in said housing for movement between a release portion whereat said slideable belt slides freely through said upper and lower slot means, and a snubbing position whereat said snubbing bar abuts and frictionally restrains said slideable belt, said folded loop folding along said upper and lower slot means and along a portion of said snubbing bar which is disposed behind said upper and lower slot means in said release position so that tension on said adjustable length belt straightens that folded loop between said upper and lower slot means and pushes said snubbing bar forward into said snubbing position.
Claim 3
Dependent Claim
41 words
An assembly according to claim 1 wherein an inertia sensitive locking retractor reel is connected to said adjustable length belt portion to lock the same preventing extension of said adjustable length belt from said reel during rapid decelleration of said vehicle.
Claim 4
Dependent Claim
25 words
An assembly according to claim 2 wherein a biasing means retains said snubbing bar in said release position when said belts are not in tension.
Claim 5
Dependent Claim
14 words
An assembly according to claim 3 wherein said biasing means is a leaf spring.
Claim 6
Dependent Claim
18 words
An assembly according to claim 1 wherein an aperture of said snubbing bar receives said folded loop therethrough.
