Abstract
Abstract Clamping means for a strap comprises a support member having a concave surface and a guide member having a convex surface. The guide member is pivotally mounted on the support member for angular movement between a first position in which the concave and convex surfaces are spaced apart by a distance greater than the uncompressed thickness of the strap and a second position in which the concave and convex surfaces are spaced apart by a distance less than the uncompressed thickness of the strap. The guide member further comprises a lobe so positioned in relation to the convex surface that the length of the path of the strap extending from a first predetermined location, round the lobe and between the concave and convex surfaces (24, 48), to a second predetermined location decreases as the guide member pivots from its first position to its second position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
181 words
Clamping means for a strap comprising a support member having a concave surface, a guide member having a convex surface and blocking means for controlling movement of the guide member relative to the support member, the guide member being pivotally mounted on the support member for angular movement between a first position in which the concave and convex surfaces are spaced apart by a distance greater than the uncompressed thickness of the strap and a second position in which the concave and convex surfaces are spaced apart by a distance less than the uncompressed thickness of the strap, the guide member further comprising a lobe so positioned in relation to the convex surface that the length of the path of the strap extending from a first predetermined location, round the lobe and between the concave and convex surfaces, to a second predetermined location decreases as the guide member pivots from its first position to its second position and the blocking means being arranged to retain the guide member in its first position until tension in the strap exceeds a predetermined value.
Claim 2
Dependent Claim
181 words
Clamping means for a strap comprising a support member having a concave surface, a guide member having a convex surface and blocking means for controlling movement of the guide member relative to the support member, the guide member being pivotally mounted on the support member for angular movement between a first position in which the concave and convex surfaces are spaced apart by a distance greater than the uncompressed thickness of the strap and a second position in which the concave and convex surfaces are spaced apart by a distance less than the uncompressed thickness of the strap, the guide member further comprising a lobe so positioned in relation to the convex surface that the length of the path of the strap extending from a first predetermined location, round the lobe and between the concave and convex surfaces, to a second predetermined location decreases as the guide member pivots from its first position to its second position and the blocking means being arranged to retain the guide member in its first position until tension in the strap exceeds a predetermined value.
Claim 3
Dependent Claim
22 words
Clamping means according to claim 1, wherein the blocking means comprises means for resiliently biasing the guide member into its first position.
Claim 4
Dependent Claim
23 words
Clamping means according to claim 1, wherein the blocking means comprises frangible means adapted to secure the guide member in its first position.
Claim 5
Dependent Claim
47 words
Clamping means according to claim 1, wherein the distance between the convex and concave surfaces when the guide member is in its second position decreases along the path of the strap from the end nearer the second predetermined location to the end nearer the first predetermined location.
Claim 6
Dependent Claim
29 words
Clamping means according to claim 4, wherein the decrease in width of the gap is arranged to take place uniformly, as the guide member moves towards its second position.
Claim 7
Dependent Claim
25 words
Clamping means according to claim 1, wherein the guide member is provided with means for preventing lateral displacement of the strap relative to the lobe.
Claim 8
Dependent Claim
31 words
Clamping means according to claim 6, wherein said means for preventing lateral displacement comprises projections extending from the lobe at each end of the guide member away from the pivotal mounting.
Claim 9
Dependent Claim
37 words
Clamping means according to claim 7, wherein the ends of said projections are interconnected by a bridge formation so that one surface of the bridge formation and the confronting surface of the lobe together form a slot.
Claim 10
Dependent Claim
25 words
Clamping means according to claim 8, wherein the said slot is curved with the central region thereof closest to the axis of the pivotal mounting.
Claim 11
Dependent Claim
24 words
Clamping means according to claim 1, wherein the support member and guide member together comprise the shoulder anchorage of a vehicle safety belt system.
