Abstract
Abstract A headlight for motor vehicles which together with its optically effective parts such as light source, reflector and possibly a diffusion lens is retained within a housing. This housing is closed off by a diffusion lens or by a cover glass and is pivotal about an axis extending essentially in the longitudinal direction of the vehicle into an extended use position and into a retracted nonuse position. This axis is positioned at an acute angle with respect to the diffusion lens, and the headlight, respectively, the housing is rotated in the vehicle transverse direction about this so-positioned axis into two end positions (use position and nonuse position) by means of a tumbling movement.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
107 words
A headlight for vehicles, comprising housing means in which the headlight together with its optically effective parts is retained, transparent cover means for closing off said housing means, and means for rotating said housing means about an axis extending essentially in the longitudinal direction of the vehicle into an extended use position and into a nonuse position, the rotating axis being inclined with respect to the transparent cover means at an acute angle, and at least one of headlight and housing means being rotatable in the vehicle transverse direction about the thus-positioned axis into the two end positions of the headlight by means of a rotary movement.
Claim 2
Dependent Claim
107 words
A headlight for vehicles, comprising housing means in which the headlight together with its optically effective parts is retained, transparent cover means for closing off said housing means, and means for rotating said housing means about an axis extending essentially in the longitudinal direction of the vehicle into an extended use position and into a nonuse position, the rotating axis being inclined with respect to the transparent cover means at an acute angle, and at least one of headlight and housing means being rotatable in the vehicle transverse direction about the thus-positioned axis into the two end positions of the headlight by means of a rotary movement.
Claim 3
Dependent Claim
17 words
A headlight according to claim 1, wherein the optically effective parts include a light source and reflector.
Claim 4
Dependent Claim
26 words
A headlight according to claim 2, wherein the optically effective parts further include a diffusion lens and wherein said transparent cover means is a cover glass.
Claim 5
Dependent Claim
15 words
A headlight according to claim 2, wherein said transparent cover means is a diffusion lens.
Claim 6
Dependent Claim
40 words
A headlight according to claim 1, wherein one of housing means and headlight is rotatable through an angle of at least 180° and assumes its respective end position at an angle of rotation of about 0° and of about 180°.
Claim 7
Dependent Claim
61 words
A headlight according to claim 1, wherein the pivot axis is inclined within a vertical longitudinal plane at an angle with respect to an ideal axis extending perpendicularly to the transparent cover means, and said angle corresponds substantially to the bisector of the angle between the transparent cover means in the use position and the said nonuse position of the headlight.
Claim 8
Dependent Claim
29 words
A headlight according to claim 1, wherein the transparent cover means as well as the opening in the body are constructed axially symmetrically with respect to the pivot axis.
Claim 9
Dependent Claim
40 words
A headlight according to claim 1, wherein the transparent cover means is visible in the one end position and extends flush with the body surface and is erected in the other end position of the headlight rotated through about 180°.
Claim 10
Dependent Claim
35 words
A headlight according to claim 8, wherein one of erected headlight and housing means is located with its lower part inside of the body and protrudes with its upper part freely beyond the body contour.
Claim 11
Dependent Claim
51 words
A headlight according to claim 8, wherein the reflector together with the light source is arranged in the upper part of the erected housing means and wherein the lowest point of the reflector is located approximately in a common horizontal plane with the lowest point of the opening in the body.
Claim 12
Dependent Claim
35 words
A headlight according to claim 1, wherein, in addition to the main headlight, an auxiliary headlight which is integrated into the housing means, is arranged producing light signals in said nonuse position of the headlight.
Claim 13
Dependent Claim
45 words
A headlight according to claim 1, wherein the housing means is provided in its rear wall with an opening covered off by a transparent cover means, behind which is retained a fixed auxiliary headlight that is arranged producing light signals in the retracted nonuse position.
Claim 14
Dependent Claim
51 words
A headlight according to claim 1, further comprising a rotating motor operatively connected with a rotary shaft, the rotary motor being arranged directly behind the housing means and being supported on the body side, and said motor including at the same time a single bearing support means for the housing means.
Claim 15
Dependent Claim
32 words

Claim 16
Dependent Claim
18 words
A headlight according to claim 14, wherein said last-mentioned means includes a gear transmission or a belt drive.
Claim 17
Dependent Claim
29 words
A headlight according to claim 6, wherein the transparent cover means as well as the opening in the body are constructed axially symmetrically with respect to the pivot axis.
Claim 18
Dependent Claim
40 words
A headlight according to claim 16, wherein the transparent cover means is visible in the one end position and extends flush with the body surface and is erected in the other end position of the headlight rotated through about 180°.
Claim 19
Dependent Claim
35 words
A headlight according to claim 17, wherein one of erected headlight and housing means is located with its lower part inside of the body and protrudes with its upper part freely beyond the body contour.
Claim 20
Dependent Claim
51 words
A headlight according to claim 18, wherein the reflector together with the light source is arranged in the upper part of the erected housing means and wherein the lowest point of the reflector is located approximately in a common horizontal plane with the lowest point of the opening in the body.

Dependent Claim
35 words
A headlight according to claim 19, wherein, in addition to the main headlight, an auxiliary headlight which is integrated into the housing means, is arranged producing light signals in said nonuse position of the headlight.
Claim 22
Dependent Claim
44 words
A headlight according to claim 19, wherein the housing means is provided in its rear wall with an opening covered off by a transparent cover means, behind which is retained a fixed auxiliary headlight that is arranged producing light signals in said nonuse position.
Claim 23
Dependent Claim
51 words
A headlight according to claim 19, further comprising a rotating motor operatively connected with a rotary shaft, the rotary motor being arranged directly behind the housing means and being supported on the body side, and said motor including at the same time a single bearing support means for the housing means.
