Abstract

A vehicle with a front windshield and a dashboard, which has a ventilation device with a defroster air outlet, and which has a head-up display integrated into the dashboard and has a front windshield projector, and a shielding frame, which delimits a projection passage, through which the front windshield projector projects optical information onto the front windshield and/or onto a combiner screen disposed in the region of the front windshield. The shielding frame is formed closed in the form of a frame with a front frame part, facing the front windshield, and a rear frame part facing away therefrom, which are connected to one another via side frame parts. The front frame part of the shielding frame is made double-walled with an inner wall, delimiting the projection passage, and an outer wall facing the front windshield, which form the defroster air outlet therebetween.

First claim

What is claimed is:

1. A vehicle comprising:
an interior with a portion thereof being delimited on a front by a front windshield and a dashboard, which has a ventilation device with a defroster air outlet, via which the front windshield is acted upon by a defroster air flow; and
a head-up display integrated into the dashboard and has a front windshield projector and a shielding frame that delimits a projection passage through which the front windshield projector projects optical information onto the front windshield and/or onto a combiner screen disposed in a region of the front windshield, wherein the shielding frame at least partially shields the front windshield projector from incident light,
wherein the shielding frame is formed closed in a form of a frame with a front frame part facing the front windshield in a vehicle longitudinal direction, and a rear frame part facing away therefrom, which are connected to one another via side frame parts,
wherein the front frame part of the shielding frame is made double-walled with an inner wall delimiting the projection passage, and an outer wall facing the front windshield, wherein the defroster air outlet is formed between the inner wall and the outer wall, and
wherein an upper end, in a vehicle vertical direction, of the outer wall of the front frame part of the shielding frame, and/or side shaft walls of the side frame parts and/or a rear shaft wall of the rear frame part, merge into an outwardly angled support flange which is supported on an opening edge region of a mounting opening in the dashboard.

2. The vehicle according to claim 1 , wherein the inner wall of the front frame part of the shielding frame forms a front shaft wall which, together with a rear shaft wall of the rear frame part and side shaft walls of the side frame parts, delimit the projection passage, and the front shaft wall, the rear shaft wall and the side shaft walls merge into one another in a closed manner at inside corners and/or the shaft walls are all formed with a completely closed surface and/or planar.

3. The vehicle according to claim 1 , wherein the support flange is supported on the opening edge region of the mounting opening in the dashboard by an upper rib and a lower guide, which are molded onto the support flange.

4. The vehicle according to claim 3 , wherein the support flange, closed in the form of a frame, surrounds the projection passage and the defroster air outlet.

5. The vehicle according to claim 3 , wherein the support flange, angled away from the outer wall of the front frame part of the shielding frame, is spaced from the front windshield by an airflow gap through which a windshield base airflow for blowing air at the windshield base is guided along the front windshield and wherein the windshield base airflow and the defroster airflow are merged downstream of an outlet opening of the defroster air outlet.

6. The vehicle according to claim 1 , wherein lower edges of the projection passage, facing the front windshield projector, are unattached or spaced from the front windshield projector by a free mounting gap, or wherein the front windshield projector, independent of the shielding frame, is attached to a module cross member or a windshield cross member of the vehicle body.

7. The vehicle according to claim 1 , wherein the dashboard has a visible dashboard support and a main dashboard body, which is covered and concealed from view by the dashboard support, wherein at least one defroster channel is formed in the main dashboard body, which is fluidically connected to the defroster air outlet via a channel opening, and wherein the at least one defroster channel is delimited upwardly in the vehicle vertical direction by an upper channel wall of the dashboard support and downwardly in the vehicle vertical direction by a lower channel wall of the main dashboard body.

8. The vehicle according to claim 7 , wherein the inner wall of the front frame part of the shielding frame is connected in an airtight manner to a channel opening edge of the lower channel wall, wherein a support flange angled away from the outer wall of the front frame part of the shielding frame is connected in an airtight manner to a channel opening edge of the upper channel wall via a connecting element, and wherein the outer wall of the front frame part of the shielding frame is spaced from the main dashboard body by a clearance or in contrast is unattached.

9. The vehicle according to claim 8 , wherein a side of the inner wall facing away from the projection passage has a connection contour for connecting the channel opening edge of the lower channel wall of the main dashboard body to the inner wall of the front frame part, so that the channel opening edge of the lower channel wall of the main dashboard body is connected and concealed from view on the side facing away from the projection passage.

10. A vehicle comprising:
an interior with a portion thereof being delimited on a front by a front windshield and a dashboard, which has a ventilation device with a defroster air outlet, via which the front windshield is acted upon by a defroster air flow; and
a head-up display integrated into the dashboard and has a front windshield projector and a shielding frame that delimits a projection passage through which the front windshield projector projects optical information onto the front windshield and/or onto a combiner screen disposed in a region of the front windshield, wherein the shielding frame at least partially shields the front windshield projector from incident light,
wherein the shielding frame is formed closed in a form of a frame with a front frame part facing the front windshield in a vehicle longitudinal direction, and a rear frame part facing away therefrom, which are connected to one another via side frame parts,
wherein the front frame part of the shielding frame is made double-walled with an inner wall delimiting the projection passage, and an outer wall facing the front windshield, wherein the defroster air outlet is formed between the inner wall and the outer wall,
wherein the dashboard has a visible dashboard support and a main dashboard body, which is covered and concealed from view by the dashboard support, wherein at least one defroster channel is formed in the main dashboard body, which is fluidically connected to the defroster air outlet via a channel opening, and
wherein the at least one defroster channel is delimited upwardly in the vehicle vertical direction by an upper channel wall of the dashboard support and downwardly in the vehicle vertical direction by a lower channel wall of the main dashboard body.
