Abstract
Abstract An adjusting device for the point of articulation or the point of deflection of a safety belt in automotive vehicles permits continuous adjustment of the angle of articulation for the safety belt in contact with the shoulder of the vehicle occupant to a predetermined value with the aid of an electric pickup for the angle of articulation, arranged at the point of articulation or deflection, and a comparison circuit connected after this pickup, which comparison circuit contains the predetermined value.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
130 words
An adjusting device for the point of articulation or the point of deflection of a safety belt in automotive vehicles, said adjusting device comprising: slide means, constituting the point of articulation or deflection; guide means carrying said slide means where said slide means are vertically adjustable in said guide means so that the angle of articulation of the safety belt resting on the shoulder of the vehicle occupant has a first predetermined value; and circuit means comprising: electric pickup means for sensing the angle of articulation of the safety belt, a comparison circuit means responsive to said pickup, said comparison circuit means containing a reference of said first predetermined value and operable to adjust the slide means when the actual angle of articulation does not equal said first predetermined value.
Claim 2
Dependent Claim
130 words
An adjusting device for the point of articulation or the point of deflection of a safety belt in automotive vehicles, said adjusting device comprising: slide means, constituting the point of articulation or deflection; guide means carrying said slide means where said slide means are vertically adjustable in said guide means so that the angle of articulation of the safety belt resting on the shoulder of the vehicle occupant has a first predetermined value; and circuit means comprising: electric pickup means for sensing the angle of articulation of the safety belt, a comparison circuit means responsive to said pickup, said comparison circuit means containing a reference of said first predetermined value and operable to adjust the slide means when the actual angle of articulation does not equal said first predetermined value.
Claim 3
Dependent Claim
35 words
The adjusting device according to claim 1, further comprising a drive mechanism for the slide means, wherein said comparison circuit means controls an electric motor means serving a electric drive means for said drive mechanism.
Claim 4
Dependent Claim
25 words
The adjusting device according to claim 2, further comprising a spindle driven by said electric motor means for the vertical adjustment of the slide means.
Claim 5
Dependent Claim
24 words
The adjusting device according to claim 1, further comprising means for activating the comparison circuit means only when the safety belt has been locked.
Claim 6
Dependent Claim
33 words
The adjusting device according to claim 4, wherein said means for activating comprises a switch means connected in the comparison circuit means, said switch means being closed when the safety belt is locked.
Claim 7
Dependent Claim
29 words
The adjusting device according to claim 2, wherein end position switches are contained in the path of movement of said slide means, said switches deactivating the electric motor means.
Claim 8
Dependent Claim
34 words
The adjusting device according to claim 1, wherein the first predetermined value of the angle of articulation is preset to a specific value dependent upon the specific vehicle the adjusting device is used on.
Claim 9
Dependent Claim
20 words
The adjusting device according to claim 1, wherein the pickup means for the angle of articulation comprises a rotary potentiometer.
Claim 10
Dependent Claim
22 words
The adjusting device according to claim 8, wherein the rotary potentiometer is integrated within a turning knuckle adjusting the angle of articulation.
Claim 11
Dependent Claim
16 words
The adjusting device according to claim 1, further comprising means to adjust said first predetermined value.
Claim 12
Dependent Claim
35 words
The adjusting device according to claim 10, further comprising: a drive mechanism for the slide means, wherein said comparison circuit means controls an electric motor means serving an electric drive means for said drive mechanism.
Claim 13
Dependent Claim
29 words
The adjusting device according to claim 11, wherein end position switches are contained in the path of movement of said slide means, said switches deactivating the electric motor means.
Claim 14
Dependent Claim
25 words
The adjusting device according to claim 11, further comprising: a spindle driven by said electric motor means for the vertical adjustment of the slide means.
Claim 15
Dependent Claim
24 words
The adjusting device according to claim 10, further comprising: means for activating the comparison circuit means only when the safety belt has been locked.
Claim 16
Dependent Claim
33 words
The adjusting device according to claim 14, wherein said means for activating comprises: a switch means connected in the comparison circuit means, said switch means being closed when the safety belt is locked.
Claim 17
Dependent Claim
34 words
The adjusting device according to claim 10, wherein the first predetermined value of the angle of articulation is preset to a specific value dependent upon the specific vehicle the adjusting device is used on.
Claim 18
Dependent Claim
20 words
The adjusting device according to claim 10, wherein the pickup means for the angle of articulation comprises a rotary potentiometer.
Claim 19
Dependent Claim
22 words
The adjusting device according to claim 17, wherein the rotary potentiometer is integrated within a turning knuckle adjusting the angle of articulation.
