Abstract
Abstract A mudguard flap for attachment to a motor vehicle is provided having a flap main body and an adapter protrusion disposed upwardly from the flap main body. The adapter protrusion has a mounting area for attaching the flap to a fender-fold and for adjusting the flap to the chassis of a motor vehicle. In the present invention the adapter protrusion has a bending line thereon, which bending line follows generally the contour of the vehicle chassis in the vicinity of the place of attachment of the mudguard flap. The mounting area is bent along the bending line and is displaced from the plane of the unbent portion of the adapter protrusion to provide a bent angle of inclination, which when the mudguard flap is attached to the fender-fold results in the unbent portion of the adapter protrusion and the flap main body being at least generally parallel with the axis of the wheel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
In a mudguard flap for attachment directly to the fender-fold of a motor vehicle, behind a vehicle wheel said mudguard flap having a flap main body and an adapter protrusion disposed upwardly from the flap main body, said adapter protrusion having a mounting area for attaching the flap to the fender-fold and for aligning the flap to the chassis of a motor vehicle, the improvement comprising the adapter protrusion having a bending line thereon, said bending line following generally the contour of the vehicle chassis in the vicinity of the place of attachment of the mudguard flap, said mounting area being bent forwardly along said bending line and being displaced from the plane of the unbent portion of the adapter protrusion and the flap main body to provide a bent angle of inclination of from 5° to 25°, whereby when said forwardly bent out mounting area of the mudguard flap is attached to a fender-fold, the unbent portion of the adapter protrusion and the flap main body are at least generally parallel with the axis of the wheel adjacent the mudguard flap.
Claim 2
Dependent Claim
182 words
In a mudguard flap for attachment directly to the fender-fold of a motor vehicle, behind a vehicle wheel said mudguard flap having a flap main body and an adapter protrusion disposed upwardly from the flap main body, said adapter protrusion having a mounting area for attaching the flap to the fender-fold and for aligning the flap to the chassis of a motor vehicle, the improvement comprising the adapter protrusion having a bending line thereon, said bending line following generally the contour of the vehicle chassis in the vicinity of the place of attachment of the mudguard flap, said mounting area being bent forwardly along said bending line and being displaced from the plane of the unbent portion of the adapter protrusion and the flap main body to provide a bent angle of inclination of from 5° to 25°, whereby when said forwardly bent out mounting area of the mudguard flap is attached to a fender-fold, the unbent portion of the adapter protrusion and the flap main body are at least generally parallel with the axis of the wheel adjacent the mudguard flap.
Claim 3
Dependent Claim
63 words
A mudguard flap according to claim 1 wherein the angle of inclination of the mounting area is larger than the angle of the fender-fold in the vicinity of the place of attachment of the mudguard flap whereby the unbent portion of the adapter protrusion and the flap main body are at an inward and rearward angle to the axis of the adjacent wheel.
Claim 4
Dependent Claim
45 words
A mudguard flap according to claim 1 or claim 2 wherein the bending line is curved and the inclination of the bending line in the lower and middle sections thereof, has an average angle of at least 20° to 25° with respect to the vertical.
Claim 5
Dependent Claim
22 words
A mudguard flap according to claim 3 wherein said angle of the inclination of the bending line is from 35° to 45°.
Claim 6
Dependent Claim
24 words
A mudguard flap according to claim 1 wherein the bending line runs generally parallel to a running inner curved edge of the adapter protrusion.
Claim 7
Dependent Claim
15 words
A mudguard flap according to claim 1 wherein the bending line includes a straight line.
Claim 8
Dependent Claim
56 words
A mudguard flap according to claim 1 wherein in addition to the bend of the mounting area, an upper edge arrea of the flap main body is bent from the plane of the remaining part of the adapter protrusion and the flap main body in the same direction as the mounting area of the adapter protrusion.
Claim 9
Dependent Claim
22 words
A mudguard flap according to claim 7 wherein the upper edge area is bent about an extension of the said bending line.
Claim 10
Dependent Claim
49 words
A mudguard flap according to claim 7 or claim 8 wherein adjacent to the bent upper edge area there is provided an intermediate area which is bent in the same direction as the upper edge area but the bend is less than the bend of the upper edge area.
Claim 11
Dependent Claim
25 words
A mudguard flap according to claim 9 wherein the intermediate area is bent about an extension of the bending line of the upper edge area.
Claim 12
Dependent Claim
47 words
A mudguard flap according to claim 1 wherein the inner side edge of the flap main body, when assembled on a vehicle, is bent in the direction opposite to that of the bend of the mounting area, in respect to the plane of the flap main body.
Claim 13
Dependent Claim
71 words
A mudguard flap according to claim 1 having cut out upper and inner corner edges of the flap main body and adjoining the cut out corner edges is a membrane, said membrane being attached to the flap main body and made of a rubber-elastic material, and wherein from an exterior edge of the membrane to connection between the membrane and the flap main body are a plurality of preset breaker lines.
Claim 14
Dependent Claim
28 words
A mudguard flap according to claim 12 wherein the preset breaker lines diverge from the exterior edge of the membrane to the connection with the flap main body.
