Abstract
Abstract The locking element or latch (5) is embodied from a metal plate and comprises a first pair of articulation tabs (13), a second pair of tabs (19) to receive strains, these tabs being received in corresponding openings (14, 20) formed in the flanges (15) of base (1). The retaining member (7) of the latch is guided in displacement in an L-shaped cutout (26) and is associated with a floating contact with a rocker (8) articulated on ejector (4). Push button (10) comprises engagement surfaces (34) and (35) cooperating selectively with locking member (7) and ejector (4) and ramps (18) to assist the lifting of the latch. A single spring (9) serves to actuate, and place under tension, all of the moving parts of the buckle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
209 words
Closure buckle for a safety belt system comprising: a base defining a path of introduction for a tongue having at least one latch aperture, a latch locking element, arranged to tilt vertically in the base around its rear part and having at its front part at least one projecting catch capable of cooperating with the latch aperture of the tongue, in a locked configuration, an ejector slidably displaceable in the base in the path of the tongue, a retaining member for the locking element in the locked configuration, displaceable between a first position of retention of the locking element and a second position of release, an elastic means acting to urge the retaining member toward its first position, and a push button having first means of engagement capable of cooperating, when the push button is depressed, with the retaining number to displace it from its first position toward its second position, characterized in that the push button (10) comprises a second means of engagement having ramps (18) capable of cooperating, when the push button is depressed, with the front part (17) of locking element (5) and assisting to lift the latter after the first means of engagement (34) has begun to displace retaining member (7) from its first position.
Claim 2
Dependent Claim
209 words
Closure buckle for a safety belt system comprising: a base defining a path of introduction for a tongue having at least one latch aperture, a latch locking element, arranged to tilt vertically in the base around its rear part and having at its front part at least one projecting catch capable of cooperating with the latch aperture of the tongue, in a locked configuration, an ejector slidably displaceable in the base in the path of the tongue, a retaining member for the locking element in the locked configuration, displaceable between a first position of retention of the locking element and a second position of release, an elastic means acting to urge the retaining member toward its first position, and a push button having first means of engagement capable of cooperating, when the push button is depressed, with the retaining number to displace it from its first position toward its second position, characterized in that the push button (10) comprises a second means of engagement having ramps (18) capable of cooperating, when the push button is depressed, with the front part (17) of locking element (5) and assisting to lift the latter after the first means of engagement (34) has begun to displace retaining member (7) from its first position.
Claim 3
Dependent Claim
95 words
Buckle according to claim 1, characterized in that the locking element (5) is a metal plate, base (1) being a U shaped metal plate having flanges (15), the locking element (5) being supported pivotally in the base (1) by a first pair of tabs 113) formed at its rear end and received in first profiled ports (14) formed in the flanges (15), and the locking element (5) having, in front of the first pair of tabs (13), a second pair of tabs (19) received loosely in second profiled ports (20) formed in the flanges (15).
Claim 4
Dependent Claim
66 words
Buckle according to claim 2, characterized in that the second ports (20) are formed so that, in the absence of a load applied on the locking element (5), the front edges of the tabs in the second pair (19) do not bear against the adjacent edges of the second ports (20), and that the base (1) includes an opening (38) adapted to receive projecting catch (6).
Claim 5
Dependent Claim
50 words
Buckle according to one of the preceding claims, characterized in that the retaining member is constituted by a bar (7), displaceable between two positions, offset longitudinally and vertically from one another, and is guided by its lateral ends in shaped cutouts (26) formed in the flanges (15) of base (1).
Claim 6
Dependent Claim
51 words
Buckle according to claim 4, characterized in that it comprises a tilting member (8) actuating the retaining member (7) and linked pivotally by its base (27) to the ejector (4), the tilting member (8) comprising an upper tab (24) with a pressure surface (25) in floating contact with retaining member (7).
Claim 7
Dependent Claim
40 words
Buckle according to claim 5, characterized in that the elastic means is constituted by a compression spring (9) whose rear end presses on the rear part of locking element (5), and whose front end presses against the tilting member (8).
Claim 8
Dependent Claim
41 words
Buckle according to claim 6, characterized in that the front end of spring (9) cooperates under floating pressure with tilting member (8), which has, on its rear face, a profiled protuberance (30) selectively engageable in the front end of spring (9).
Claim 9
Dependent Claim
33 words
Buckle according to one of the preceding claims, characterized in that the ejector (4) comprises two lateral guidance wings (22) received in elongate ports (23) formed in the flanges (15) of base (1).
Claim 10
Dependent Claim
30 words
Buckle according to claim 8, characterized in that the push button (10) comprises a second means of engagement (35) capable of cooperating with the lateral wings (22) of ejector (4).
Claim 11
Dependent Claim
28 words
Buckle according to one of the preceding claims, characterized in that the bottom (37) of base (1) comprises, in its rear part, means (41) for mounting the buckle.
