Abstract
Abstract A buckling assembly for a safety harness has two parts which can be connected and disconnected from one another. One of the parts has a member which must be actuated to allow connection and disconnection, and once the assembly is connected and closed, actuation of this member is prevented. Additionally, the two parts can only be separated in one relative orientation which will not be reached while the harness is being worn.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
A buckling assembly for a safety belt or safety harness, comprising: first and second interconnectable parts; a transverse bar on said first part; a hook on said second part for engaging around said bar; locating means for locating said second part relative to said first part; a larger diameter portion and a smaller diameter portion on the transverse bar; said hook having an opening of a width larger than the smaller diameter portion of the bar but smaller than the larger diameter portion of the bar, and a centre having a width larger than said large diameter portion; the larger and smaller diameter portions being movable longitudinally of the bar and relative to the locating means between a first position where the smaller diameter portion registers with the hook so that the hook can be received around the bar, and a second position where the larger diameter portion registers with the hook so that the hook cannot be disengaged from the bar; and immobilising means for preventing movement of the larger and smaller diameter portions into said first position.
Claim 2
Dependent Claim
179 words
A buckling assembly for a safety belt or safety harness, comprising: first and second interconnectable parts; a transverse bar on said first part; a hook on said second part for engaging around said bar; locating means for locating said second part relative to said first part; a larger diameter portion and a smaller diameter portion on the transverse bar; said hook having an opening of a width larger than the smaller diameter portion of the bar but smaller than the larger diameter portion of the bar, and a centre having a width larger than said large diameter portion; the larger and smaller diameter portions being movable longitudinally of the bar and relative to the locating means between a first position where the smaller diameter portion registers with the hook so that the hook can be received around the bar, and a second position where the larger diameter portion registers with the hook so that the hook cannot be disengaged from the bar; and immobilising means for preventing movement of the larger and smaller diameter portions into said first position.
Claim 3
Dependent Claim
19 words
An assembly as claimed in claim 1, including spring-biassing means for biassing the bar portions into said second position.
Claim 4
Dependent Claim
80 words
An assembly as claimed in claim 2, wherein the locating means are formed by two side walls on said first part, and wherein there are two sets of larger and smaller diameter portions which are biassed apart from one another against the side walls so that the smaller diameter portions extend through the side walls in the second position, the second part having two hooks which are spaced apart by a distance such that they fit between the side walls.
Claim 5
Dependent Claim
54 words
An assembly as claimed in claim 3, wherein a further reduced diameter portion is provided on the bar between the two sets of larger and smaller diameter portions, and the immobilising means locates on said further portion to prevent the two sets of larger and smaller diameter portions from being pushed towards one another.
Claim 6
Dependent Claim
24 words
An assembly as claimed in claim 3 wherein the two sets of larger and smaller diameter portions are biassed apart by an enclosed spring.
Claim 7
Dependent Claim
23 words
An assembly as claimed in claim 1 and including a lid on said first part, the immobilising means being provided on said lid.
Claim 8
Dependent Claim
29 words
An assembly as claimed in claim 1, wherein one of the interconnectable parts includes an adjusting device for adjusting the length of a strap forming part of the harness.
Claim 9
Dependent Claim
35 words
An assembly as claimed in claim 1, wherein the two parts can only be separated in a limited range of relative orientations which will not be reached while the assembly is connected and in use.
