Abstract
Abstract A receiving part for the coupling tongue of a vehicle safety belt with two spaced guides plates, a locking body for locking the tongue within the guide plate and being movable in a direction transverse to the guide plate, a lever-shaped lifting element located in the receiving part and cooperating with the locking body and being passed thereagainst by a spring. The lifting element has a projection with an oblique surface located in the path of insertion of the coupling tongue in front of the locking body so that upon insertion of the tongue into the receiving part the tongue lifts the oblique surface and projection and thereby the locking body against the spring out of the path of insertion of the coupling tongue.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
175 words
A receiving part for the coupling tongue of a safety belt for vehicles, comprising: spaced guide means for receiving said tongue therebetween, locking means for locking said tongue within said guide means when said tongue is received therebetween, said locking means being movable in said receiving part in a direction transverse to said guide means and to the direction of insertion of said tongue into said receiving part, a lever-shaped lifting element located in said receiving part and cooperating with, but being separate from, said locking means, spring means pressing said locking means against said lifting element, said lifting element having a projection with an oblique surface located in the path of insertion of said coupling tongue in front of said locking means when looking in the direction of insertion of said tongue into said receiving part, so that upon insertion of said tongue into said receiving part, said tongue lifts said oblique surface and projection and thereby said locking means out of the path of insertion of said coupling tongue against said spring means.
Claim 2
Dependent Claim
175 words
A receiving part for the coupling tongue of a safety belt for vehicles, comprising: spaced guide means for receiving said tongue therebetween, locking means for locking said tongue within said guide means when said tongue is received therebetween, said locking means being movable in said receiving part in a direction transverse to said guide means and to the direction of insertion of said tongue into said receiving part, a lever-shaped lifting element located in said receiving part and cooperating with, but being separate from, said locking means, spring means pressing said locking means against said lifting element, said lifting element having a projection with an oblique surface located in the path of insertion of said coupling tongue in front of said locking means when looking in the direction of insertion of said tongue into said receiving part, so that upon insertion of said tongue into said receiving part, said tongue lifts said oblique surface and projection and thereby said locking means out of the path of insertion of said coupling tongue against said spring means.
Claim 3
Dependent Claim
61 words
A receiving part according to claim 1, wherein said spring means is a plate spring, one end portion of which is attached to one of said guide means, the other end of said plate spring bearing against said locking means, which in turn holds said lifting element in a clamped position between said locking means and one of said guide means.
Claim 4
Dependent Claim
58 words
A receiving part according to claim 2, wherein said locking means and said lifting element are positively guided with respect to their positions relative to each other and relative to said guide means in the plane of said guide means, but are removable at a right angle to said plane after said spring means has been moved aside.
Claim 5
Dependent Claim
80 words
A receiving part according to claim 1, wherein said locking means has at least one guiding portion extending through said guide means in a direction transverse thereto and exceeding in length at least the thickness of said coupling tongue so as to maintain the engagement of said guiding portion with said guiding means even when said locking means is entirely lifted out of said coupling tongue, said guiding portion being located laterally outside the longitudinal edge of said coupling tongue.
Claim 6
Dependent Claim
38 words
A receiving part according to claim 4, wherein said guiding means of said locking means are located in close proximity to the longitudinal edges of said coupling tongue, thereby forming a sidewise guiding means for said coupling tongue.
Claim 7
Dependent Claim
21 words
A receiving part according to claim 4, wherein said locking means including its guiding portion forms one piece of sheet metal.
Claim 8
Dependent Claim
44 words
A receiving part according to claim 6, wherein said locking means is a substantially U-shaped piece, said guide portions forming the legs of said U-shaped piece and the portion of the U-shaped piece connecting said legs forming the portion which engages said coupling tongue.
Claim 9
Dependent Claim
26 words
A receiving part according to claim 4, wherein said guiding portions of said locking means extend through slit-shaped openings in lateral edges of said guide means.
Claim 10
Dependent Claim
100 words
A receiving part according to claim 1, which comprises an ejector, spring means biasing said ejector in a direction opposite to the direction of insertion of said coupling tongue and having a portion movable in the space between said guide means, said ejector portion pushing said tongue out of said receiving part, when said locking means has been lifted from its locking position, said ejector having an extension extending unto and below said locking means when the latter is in its lifted position to thereby prevent the same from returning to the locking position, when said coupling tongue is disengaged.
Claim 11
Dependent Claim
44 words
A receiving part according to claim 9, wherein said locking means forms a stop, stop means provided on said ejector and cooperating with said stop for limiting the movement of said ejector in a direction opposite the direction of insertion of said coupling tongue.
