Abstract
Abstract A position-variable belt articulation apparatus for safety belts, especially for the upper, body-mounted pivot of three-point safety belts, having a clamping element adjustable along a guide, with at least one belt holder being associated with the clamping element which is tensioned against the guide by the belt as a function of the stress on the belt. The clamping element is guided in a longitudinally adjustable manner and is swivelable about an axis transverse to the direction of longitudinal adjustment. The clamping element, in one embodiment, can have clamping jaws which cooperate with the guide and which are associated with the belt holders. In another embodiment, the two clamping jaws are articulated to one another and have curved clamping surfaces for gripping the guide firmly therebetween to keep the clamping element at the appropriate height.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
126 words
A position-variable belt articulation apparatus for a vehicle safety belt, especially for an upper articulation point at a side of a vehicle in a three-point safety belt system, characterized in that the articulation apparatus comprises a guide means, a clamping element displaceable in a longitudinal direction along the guide means, at least one belt mounting connected with said clamping element, said at least one belt mounting is stressed by the belt in dependence upon a load imposed upon the belt, and in that said clamping element is pivotable about an axis extending at right angles to the displacement direction upon a stressing of the at least one belt mounting, whereby the clamping element is clamped against the guide means by the load imposed on the belt.
Claim 2
Dependent Claim
126 words
A position-variable belt articulation apparatus for a vehicle safety belt, especially for an upper articulation point at a side of a vehicle in a three-point safety belt system, characterized in that the articulation apparatus comprises a guide means, a clamping element displaceable in a longitudinal direction along the guide means, at least one belt mounting connected with said clamping element, said at least one belt mounting is stressed by the belt in dependence upon a load imposed upon the belt, and in that said clamping element is pivotable about an axis extending at right angles to the displacement direction upon a stressing of the at least one belt mounting, whereby the clamping element is clamped against the guide means by the load imposed on the belt.
Claim 3
Dependent Claim
49 words
A belt articulation apparatus according to claim 1, characterized in that the clamping element is fashioned as a two-armed lever, a clamping jaw cooperating with the guide means is provided on one arm of the lever, and the belt mount is provided on the other arm of the lever.
Claim 4
Dependent Claim
25 words
A belt articulation apparatus according to claim 1, characterized in that the at least one belt mounting is in a guide loop of the belt.
Claim 5
Dependent Claim
23 words
A belt articulation apparatus according to claim 1, characterized in that the at least one belt mounting is formed by a guide eye.
Claim 6
Dependent Claim
135 words
A belt articulation apparatus according to claim 1, wherein the guide means is affixed to the vehicle and a belt strap serves as a guide element, characterized in that a first clamping jaw is provided, the clamping element includes a second clamping jaw hingedly joined to the first clamping jaw, the belt strap is disposed between the first and second clamping jaws so as to be clamped therebetween, and in that said second clamping jaw is displaceably guided in the guide means affixed to the vehicle so as to be vertically displaceable, the at least one belt mounting is connected with the first clamping jaw whereby a stress on the belt mounting due to a load on the safety belt effects a fixed clamping of the belt strap between the first and second clamping jaws.
Claim 7
Dependent Claim
42 words
A belt articulation apparatus according to claim 5, characterized in that each clamping jaw has a curved clamping surface, and wherein the clamping surface of said second clamping jaw is convex and the clamping surface of the first clamping jaw is concave.
Claim 8
Dependent Claim
125 words
A position-variable belt articulation apparatus for a vehicle safety belt, especially for an upper articulation point at a side of the vehicle in a three point safety belt system, characterized in that the articulation apparatus comprises a clamping element adjustable along a guide means, belt mounts are connected with the clamping element, said belt mounts are stressed against the guide means by the belt in dependence upon a load imposed upon the belt, and in that the clamping element includes clamping jaws associated with the belt mounts, the guide means are disposed between the clamping jaws, said clamping jaws are acted upon and stressable by the belt in dependence upon a load exerted thereon so as to be clamped against the guide means disposed therebetween.
Claim 9
Dependent Claim
125 words
A position-variable belt articulation apparatus for a vehicle safety belt, especially for an upper articulation point at a side of the vehicle in a three point safety belt system, characterized in that the articulation apparatus comprises a clamping element adjustable along a guide means, belt mounts are connected with the clamping element, said belt mounts are stressed against the guide means by the belt in dependence upon a load imposed upon the belt, and in that the clamping element includes clamping jaws associated with the belt mounts, the guide means are disposed between the clamping jaws, said clamping jaws are acted upon and stressable by the belt in dependence upon a load exerted thereon so as to be clamped against the guide means disposed therebetween.
Claim 10
Dependent Claim
61 words
A belt articulation apparatus according to claim 7, characterized in that the clamping element includes intersecting levers, means are provided for pivoting the levers relative to each other about a pivot axle, the clamping jaws are provided on the levers on one side of the pivot axle and the belt mountings are provided on the other side of the pivot axle.
Claim 11
Dependent Claim
36 words
A belt articulation apparatus according to claim 8, characterized in that one of the levers of the clamping element is straight and the other of the levers is angled in a zone of the pivot axle.
Claim 12
Dependent Claim
23 words
A belt articulation apparatus according to claim 8, characterized in that means are provided for pretensioning the clamping jaws against the guide means.
Claim 13
Dependent Claim
26 words
A belt articulation apparatus according to claim 10, characterized in that the pretensioning means includes a tension spring arranged between the levers of the clamping element.
Claim 14
Dependent Claim
24 words
A belt articulation apparatus according to one of claims 8, 9, 11 or 7, characterized in that the guide means is a belt strap.
Claim 15
Dependent Claim
25 words
A belt articulation apparatus according to one of claims 8 or 7, characterized in that the belt mounts are each formed by a guide eye.
Claim 16
Dependent Claim
22 words
A belt articulation apparatus according to claim 7, characterized in that the belt mountings are in a guide loop of the t.
