Abstract

Abstract A rear for passenger automobiles of the type having a pivotal hatch inserted in a rear opening of a vehicle body and extending in a smooth flowing line toward the rear and including a window in a transversely extending lower frame adjoining the window, is provided, in accordance with the preferred embodiment of the invention, with an aerodynamic device on the lower frame of the hatch, the aerodynamic device having sections extended laterally from the hatch along lateral body parts of the vehicle. The laterally extended sections should preferably merge into and terminate at the lateral body parts. Additionally, in hatches where frames are provided extending in the longitudinal direction of the vehicle, ribs are provided extending away from the aerodynamic device, running along the frames, and forming an aerodynamic unit with the aerodynamic device. The ribs preferably taper in height in the direction away from the aerodynamic device so as to merge into and terminate near upper ends of the longitudinally directed frames of the hatch.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 155 words
Rear for passenger automobiles comprising a pivotable hatch inserted in an opening of a vehicle body, said body extending in a smoothly flowing line toward the rear, said hatch including a window, a transversely extending lower frame of the hatch, adjoining tthe window, being bounded by lateral body parts extending obliquely to the driving direction, characterized in that an aerodynamic device is provided on the lower frame of the hatch, said device having sections extended laterally from the hatch along the lateral body parts, wherein the aerodynamic device is comprised of an elastic member, wherein the elastic member has a recess on a side facing the lower frame of the hatch, this recess being delimited at least along certain sections by a bracket, said bracket being provided with a holding fixture serving for attaching the aerodynamic device to the lower frame, characterized in that the holding fixture has a generally hat-shaped profile in cross section.
Claim 2
Dependent Claim 155 words
Rear for passenger automobiles comprising a pivotable hatch inserted in an opening of a vehicle body, said body extending in a smoothly flowing line toward the rear, said hatch including a window, a transversely extending lower frame of the hatch, adjoining tthe window, being bounded by lateral body parts extending obliquely to the driving direction, characterized in that an aerodynamic device is provided on the lower frame of the hatch, said device having sections extended laterally from the hatch along the lateral body parts, wherein the aerodynamic device is comprised of an elastic member, wherein the elastic member has a recess on a side facing the lower frame of the hatch, this recess being delimited at least along certain sections by a bracket, said bracket being provided with a holding fixture serving for attaching the aerodynamic device to the lower frame, characterized in that the holding fixture has a generally hat-shaped profile in cross section.
Claim 3
Dependent Claim 173 words
Rear for passenger automobiles comprising a pivotable hatch inserted in an opening of a vehicle body, said body extending in a smoothly flowing line toward the rear, said hatch including a window, a transversely extending lower frame of the hatch, adjoining the window, being bounded by lateral body parts extending obliquely to the driving direction, characterized in that an aerodynamic device is provided on the lower frame of the hatch, said device having sections extended laterally from the hatch along the lateral body parts, wherein the aerodynamic device is comprised of an elastic member, wherein the elastic member has a recess on a side facing the lower frame of the hatch, this recess being delimited at least along certain sections by a bracket, said bracket being provided with a holding fixture serving for attaching the aerodynamic device to the lower frame, characterized in that the elastic member comprises crosspieces arranged at an angle with respect to each other, ends of these crosspieces resting on one of the window and the lower frame, respectively.
Claim 4
Dependent Claim 173 words
Rear for passenger automobiles comprising a pivotable hatch inserted in an opening of a vehicle body, said body extending in a smoothly flowing line toward the rear, said hatch including a window, a transversely extending lower frame of the hatch, adjoining the window, being bounded by lateral body parts extending obliquely to the driving direction, characterized in that an aerodynamic device is provided on the lower frame of the hatch, said device having sections extended laterally from the hatch along the lateral body parts, wherein the aerodynamic device is comprised of an elastic member, wherein the elastic member has a recess on a side facing the lower frame of the hatch, this recess being delimited at least along certain sections by a bracket, said bracket being provided with a holding fixture serving for attaching the aerodynamic device to the lower frame, characterized in that the elastic member comprises crosspieces arranged at an angle with respect to each other, ends of these crosspieces resting on one of the window and the lower frame, respectively.
Claim 5
Dependent Claim 16 words
Rear according to claim 2, wherein said bracket is incorporated into the material of said crosspieces.
Claim 6
Dependent Claim 30 words
Rear according to claim 2, wherein an air guide section forming part of said aerodynamic device projects rearwardly in an obliquely upward direction from a junction of said cross pieces.
