Description

Technical Field

[0001] The invention relates to a projection device for a vehicle, a projection system for a vehicle, a vehicle and a method for projection in a vehicle. Background Art

[0002] Nowadays, the demand for infotainment of vehicle passengers is growing day by day. The visual display content provided to vehicle passengers inside the vehicle is no longer limited to the simple display of vehicle status and / or parameters. Vehicle passengers are more willing to enjoy infotainment content in the car, such as reading e-books, watching video images, viewing photos, browsing the web, etc. For this reason, there are mainly two display schemes in the vehicle: direct display and head-up display, where the direct display can be understood as a liquid crystal display (LC-Display, i.e., liquid crystal display), organic light-emitting semiconductor display (OLED-Display, i.e., organic light-emitting semiconductor), etc. arranged on the surface of the interior of the vehicle; while the head-up display (HUD-Display, i.e., head-up display) projects a virtual image toward the front windshield, so that the front passengers of the vehicle can view the display image superimposed on the road ahead while maintaining their head posture or viewing direction.

[0003] However, the display solutions existing in the prior art still have certain shortcomings. First of all, both direct displays and head-up displays only provide display images in fixed areas. Moreover, in order to view the displayed images, vehicle occupants need to remain in a sitting position to see the direct display on the front windshield or dashboard, and it is particularly difficult to view in a more comfortable lying position. In addition, the head-up display cannot present good image quality and viewing experience for entertainment needs due to its limited brightness and / or the light transmittance of the glass reflective medium, while the direct display is expensive to manufacture and assemble, especially when arranged over a large area on the dashboard, which will also cause an increase in weight and lead to a reduction in the vehicle's driving power and an increase in energy demand. Summary of the invention

[0004] The task of the present invention is to provide a projection device for a vehicle, a projection system for a vehicle, a vehicle and a method for projection in a vehicle, which can improve the above-mentioned deficiencies in the prior art and provide vehicle occupants with a comfortable and excellent viewing experience flexibly and at low cost.

[0005] A first aspect of the present invention relates to a projection device for a vehicle, wherein the projection device is arranged on a B-pillar of the vehicle and is pivotally supported on the B-pillar at least with respect to a lateral direction of the vehicle, so that the projection device can use multiple interior parts in the vehicle as projection screens and project an image onto one of the multiple interior parts.

[0006] According to the present invention, the B-pillar of a vehicle refers to a vertically extending pillar connecting the top side beam and the door sill of the vehicle and located between the front and rear doors. The projection device according to the present invention is arranged on the B-pillar of the vehicle, in particular on the decorative panel of the B-pillar. It goes without saying that in order to perform projection in the vehicle, the projection device should be arranged in the upper section of the B-pillar. According to the specific vehicle design, the projection device can be arranged on the left or right B-pillar, or a total of two projection devices are arranged on the left and right B-pillars respectively. In addition, the projection device can be arranged, for example, above the seat belt anchorage in the B-pillar. The projection device can also be arranged directly on the B-pillar in particular in a vehicle in which the seat belt anchorage in the B-pillar is eliminated.

[0007] According to the present invention, the projection device is pivotably supported on the B-pillar at least with respect to the transverse direction of the vehicle, so that the projection device can use multiple interior parts in the vehicle as projection screens and project images onto one of the multiple interior parts. Therefore, the projection device can be rotated at least around an axis extending in the transverse direction of the vehicle. Such mobility of the projection device can flexibly change the projection area of ​​the projection device, so that images can be projected onto a variety of interior parts as projection screens. For example, the projection device according to the present invention can use the dashboard and the sun visor of the vehicle as projection screens respectively: when the projection device projects onto the dashboard, the projection can be performed on the dashboard or a screen corresponding to the dashboard; and after the projection device is pivoted upward with respect to the transverse direction of the vehicle, the sun visor that has been folded down can be used as a projection screen for projection.

[0008] According to the projection device of the present invention, different interior parts in the vehicle can be used as projection screens. Compared with the fixed direct display and head-up display, it can flexibly adapt to the viewing angles of the vehicle occupants in different postures, meet the comfort requirements of the vehicle occupants and bring a novel in-car entertainment experience. In particular, since the B-pillar where the projection device is set is in the middle of the vehicle, the projection direction of the pivotable projection device can effectively cover a variety of interior parts in the interior space of the vehicle, such as instrument panels, sun visors, canopies, table boards, etc., greatly enriching the possibilities of in-car display. On the one hand, since the usually opaque interior parts are used as display screens, the projection device according to the present invention can provide a significantly better display effect than the head-up display, so that the vehicle occupants can view the image clearly and without interference. On the other hand, compared with the direct display, the manufacturing and assembly cost of the projection device according to the present invention is low, the weight is light, and it saves energy.

[0009] According to an embodiment of the present invention, the projection device can be configured to be movable along the longitudinal extension direction of the B-pillar, and / or the projection device can be configured to be movable away from or closer to the B-pillar, and / or the projection device can be configured to swing around the B-pillar. Here, moving along the longitudinal extension direction of the B-pillar means that the projection device can change its height in the vehicle, that is, it can project from a higher position or a lower position in the vehicle; moving away from or closer to the B-pillar means that the projection device can change its distance relative to the B-pillar, especially the decorative panel of the B-pillar, that is, it can project closer to or farther from the position of the head of the front passenger of the vehicle; swinging around the B-pillar means that the projection device can rotate horizontally around a certain point in the B-pillar, thereby further expanding the projection range and / or avoiding possible blocking components, such as seat headrests. In the present invention, one or more of the various movement modes mentioned above can be provided in addition to the pivoting in the transverse direction of the vehicle, thereby further expanding the projection range, so that the image of the projection device can appear at more positions in the vehicle. Furthermore, the posture of the projection device can be adjusted more finely, and projection can be performed without being interfered by vehicle interior components such as seat headrests.

[0010] According to a preferred embodiment of the present invention, the projection device can be connected to the B-pillar via a universal joint; and / or the projection device can include a motor and a controller, and the controller drives the motor to adjust the posture of the projection device. In order to adjust the posture of the projection device, a universal joint or a universal joint, in particular a spherical universal joint, can be used particularly advantageously so that the projection device can freely adjust its projection direction. Without being limited to this, the projection device can also use a translation mechanism such as a ball screw, a rotation mechanism such as a gear mechanism, etc. Particularly preferably, the projection device can be equipped with a motor and a controller for driving the motor to achieve automatic electromechanical adjustment of the posture of the projection device.

[0011] A second aspect of the present invention relates to a projection system for a vehicle, comprising: a projection device according to the present invention and a plurality of interior trim parts serving as projection screens for the projection device.

[0012] According to an embodiment of the present invention, the plurality of interior parts may include: sun visors, dashboards, roofs, seats, table tops, vehicle floors, etc. The scope of interior parts should be understood broadly. Not limited thereto, in the projection device and projection system according to the present invention, the front and rear windshields or the side windows may also be used as projection areas to project images.

[0013] In order to increase the area of ​​the image, it is advantageous that the sun visor can be designed to be expandable in area. The sun visor that is flipped down in the vehicle is particularly suitable for the front seat occupants of the vehicle to view when they are lying down. In order to provide a larger projection area for the front seat occupants of the vehicle lying down, the present invention proposes that the area of ​​the sun visor is designed to be expandable.

[0014] According to a preferred embodiment of the present invention, the sun visor may include a main sun visor and at least one auxiliary sun visor for expansion, and the auxiliary sun visor can be directly or indirectly connected to the main sun visor, so that each auxiliary sun visor can be coplanar with the main sun visor in the expanded state. Here, in order to expand the area of ​​the sun visor, at least one auxiliary sun visor is provided, and the at least one auxiliary sun visor can be connected and spliced ​​together with the main sun visor in the same plane, thereby extending the original length and / or width of the sun visor to obtain a larger projection area. In particular, a curtain is arranged on the side of the sun visor and the at least one auxiliary sun visor facing the front occupants of the vehicle to enhance the display effect.

[0015] According to one embodiment of the present invention, the sun visor may include a telescopic support that can be extended and retracted relative to the periphery of the sun visor frame and a curtain stretched on the telescopic support, so that the curtain can be stretched on the sun visor and its telescopic support in a variable flat size, thereby also expanding the projection area.

[0016] According to one embodiment of the present invention, the auxiliary sun visor can be hingedly connected, softly connected or slidably connected to the adjacent main sun visor or another auxiliary sun visor.

[0017] According to a preferred embodiment of the present invention, the auxiliary sun visor can be connected to an adjacent main sun visor or another auxiliary sun visor by a hinge, and the hinge can be fixed in an open state of 180 degrees. Here, the various components of the sun visor can be connected to each other by hinges or hinges. Thus, the vehicle occupant can make these components coplanar with each other by opening the hinges.

[0018] Preferably, the auxiliary sun visor can be softly connected to the adjacent main sun visor or another auxiliary sun visor through fabric, and magnets that can attract each other are correspondingly arranged on the circumferential edges of the main sun visor and the auxiliary sun visor. In this way, the sun visor provided here can be manufactured cost-effectively. Similarly, the vehicle occupant only needs to simply flip open the auxiliary sun visor so that the magnets attract each other and make it coplanar with the main sun visor.

[0019] Alternatively, a slide guide structure may be formed on the main sun visor or the auxiliary sun visor. Here, the main sun visor and the auxiliary sun visor may be configured to overlap or accommodate each other. The vehicle occupant may unfold each auxiliary sun visor and make it coplanar with each other by pulling.

[0020] According to one embodiment of the present invention, a flip screen can be stored on or in the instrument panel, and the flip screen can be erected at an angle relative to the instrument panel in the extended state. Here, the flip screen is arranged on the instrument panel, for example, and the vehicle occupant can simply flip the flip screen to make it stand at a certain angle relative to the instrument panel. The projection device according to the present invention can project an image onto the erected flip screen. In particular, the flip screen is provided with a curtain on the side facing the vehicle occupant. It is also possible to store the flip screen in the instrument panel so that the vehicle occupant can make it stand at a certain angle relative to the instrument panel by pulling it out and flipping it up.

[0021] According to an embodiment of the present invention, the tabletop can be stored in an instrument panel or a seat. Here, the tabletop can for example comprise a tabletop extracted from an instrument panel, a tabletop folded from a seat back, or a tabletop removed from a seat armrest.

[0022] A third aspect of the invention relates to a vehicle comprising a projection device according to the invention or a projection system according to the invention.

[0023] A fourth aspect of the invention relates to a method for projection in a vehicle, which method uses a projection device according to the invention or a projection system according to the invention for projection onto one of a plurality of interior trim parts serving as a projection screen.

[0024] According to a preferred embodiment of the present invention, the projection direction of the projection device is changed in response to the input of the vehicle occupant and / or the adjustment of the seat. On the one hand, the vehicle occupant can set the projection direction of the projection device by inputting in the vehicle setting interface; for example, the interior decoration to be projected and the corresponding projection direction are selected by inputting in the vehicle setting interface. Correspondingly, the projection device can adjust the projection direction of the projection device, especially by its controller by means of the drive of the motor. On the other hand, the change of the projection direction of the projection device can be carried out according to the adjustment of the seat. For example, when the seat back is upright, the projection device projects the image onto the dashboard, the flip screen on or in the dashboard, or the table drawn out from the dashboard; and as the vehicle occupant changes the seat to a lying position, the projection device can pivot upward with respect to the lateral direction of the vehicle, thereby projecting the image onto the sun visor or the roof. In this way, the projection device can be automatically set to a projection position comfortable for the vehicle occupant according to the posture of the vehicle occupant, thereby improving the driving experience of the vehicle.

[0025] According to a preferred embodiment of the present invention, the seat can be a zero-gravity seat or a comfortable seat with a large reclining angle.

[0026] According to a preferred embodiment of the invention, the state of the interior part is changed in response to inputs from a vehicle occupant and / or adjustments to a seat. Particularly advantageously, the interior part used as a projection screen is adapted in response to inputs from a vehicle occupant and / or adjustments to a seat. To this end, the screen can be automatically extended outward for the vehicle occupant, a sun visor as described above can be deployed, a roof can be closed, etc.

[0027] It should be noted that the features, functions, effects and advantages of one aspect of the present invention can also refer to the above description of other aspects of the present invention. In addition, the various aspects described in the present invention can be combined with each other in various ways.

[0045] Figure 1 The arrangement of a projection device 1 according to the invention for a vehicle in a vehicle is shown. Figure 1 A view from the vehicle interior to the side of the vehicle is schematically shown. Here, the projection device 1 is arranged on the B-pillar 2 of the vehicle, and the projection device 1 is pivotably supported on the B-pillar 2 at least with respect to the transverse direction of the vehicle, so that the projection device 1 can use multiple interior parts in the vehicle as projection screens and project an image onto one of the multiple interior parts.

[0046] like Figure 1As shown, the B-pillar 2 connects the roof rail 3 and the door sill 4 of the vehicle and is located between the front door 5 and the rear door. The projection device 1 is arranged in the upper section of the B-pillar 2, in particular on the decorative panel of the B-pillar 2. According to the specific vehicle design, the projection device 1 can be arranged on the left or right B-pillar 2, or one projection device 1 can be arranged on each side of the B-pillar 2. In addition, the projection device can be arranged, for example, above the seat belt anchorage in the B-pillar. Here, the seat belt anchorage usually arranged on the B-pillar 2 is not shown. It goes without saying that the projection device 1 should be arranged above the seat belt anchorage in the B-pillar 2. However, the projection device 1 according to the present invention is particularly preferably arranged in a vehicle in which the seat belt anchorage is transferred to a seat, in particular a zero-gravity seat or a comfort seat with a large reclining angle.

[0047] exist Figure 1 In the figure, the arrows schematically indicate that the projection device 1 can rotate around the axis T extending in the transverse direction of the vehicle in the direction indicated by the arrow or in the opposite direction. Such mobility of the projection device 1 can flexibly change the projection area of ​​the projection device 1, so that the image can be projected onto a variety of interior parts as projection screens. Compared with the fixed direct display and head-up display, the projection device 1 can flexibly adapt to the viewing angles of the vehicle occupants in different postures, meet the comfort requirements of the vehicle occupants and bring a novel in-vehicle entertainment experience. In particular, since the B-pillar 2 where the projection device 1 is arranged is located in the middle of the vehicle, the projection direction of the pivotable projection device 1 can effectively cover most of the interior parts in the interior space of the vehicle, such as the instrument panel, sun visor, canopy, table board, etc., greatly enriching the possibility of in-vehicle display. Since the usually opaque interior parts are used as display screens, the projection device 1 can not only provide significantly better display effects than the head-up display, but also enable the vehicle occupants to view the image clearly and without interference. Moreover, compared with direct display, the projection device 1 has low manufacturing and assembly costs, is lightweight and saves energy.

[0048] Figure 2 An embodiment of the projection device 1 for a vehicle according to the present invention is shown on a B-pillar 2. Figure 2 In the embodiment, the projection device 1 can not only pivot in two directions indicated by circular arrows around an axis T extending in the transverse direction of the vehicle, but also move up and down along the longitudinal extension direction of the B-pillar (as indicated by the straight arrow) to perform projection from different heights inside the vehicle. To this end, a vertically extending guide groove 7 is provided in the B-pillar 2, especially in its decorative panel, and the projection device 1 can perform translational movement in the guide groove 7.

[0049] Figure 3 Another embodiment of the projection device 1 for a vehicle according to the present invention is shown on a B-pillar 2. Figure 3In the cross-sectional view shown, in addition to the pivoting in the transverse direction of the vehicle, the projection device 1 can also move away from or close to the B-pillar as shown by the straight arrows and can swing forward and backward around a substantially vertical axis V. Here, the projection device 1 is arranged on a guide arm 8 extending from the B-pillar 2, by means of which the distance between the projection device 1 and the B-pillar 2 can be changed and the projection device 1 can be driven to swing forward and backward.

[0050] In order to adjust the posture of the projection device more finely, Figure 2 and 3 The movement modes and mechanisms shown are merely schematic; these movement modes can be combined with each other in different ways or can be realized by mechanisms different from those shown in the figures.

[0051] Particularly preferably, the projection device 1 can be connected to the B-pillar 2 via a universal joint or a universal joint, in particular a ball universal joint, so that the projection device 1 can freely adjust its projection direction. It is also particularly preferred that a motor and a controller (not shown) for driving the motor can be configured for the projection device 1 to achieve electromechanical adjustment of the posture of the projection device.

[0052] Figure 4 A projection mode of the projection system for a vehicle according to the present invention is shown. Here, the projection system for a vehicle according to the present invention comprises the projection device 1 described above and a plurality of interior parts used as a projection screen of the projection device 1. In the current projection mode, in order to allow the vehicle occupant H in a sitting position on the seat 10 to view the image, the projection device 1 projects the image onto the upper surface of the instrument panel 9 of the vehicle at an oblique downward projection angle. Here, the upper surface of the instrument panel 9 is particularly advantageously covered with a curtain material so that the brightness of the projected image is uniform and the image quality is clear.

[0053] Figure 5 Another projection mode of the projection system for a vehicle according to the present invention is shown. In this projection mode, the projection device 1 projects the image onto the sun visor 11 of the vehicle that is folded down at an oblique upward projection angle so that the vehicle occupant H who is in a lying position on the seat 10 can view the image. Here, the side of the sun visor 11 facing the vehicle occupant is also preferably covered with a curtain material.

[0054] Here, Figure 5 The seat 10 shown is preferably a zero gravity seat or a high reclining comfort seat.

[0055] Figure 6 Another projection mode of the projection system for a vehicle according to the present invention is shown. In this projection mode, in order to allow the rear passengers of the vehicle (not shown) to view the image, the projection device 1 projects the image onto the table 12 folded out from the back side of the seat 10 at an oblique rearward projection angle.

[0056] It should be noted that Figures 4 to 6 The vehicle occupant H shown may be a co-driver or a driver, in particular a driver when the vehicle is in an automated driving mode.

[0057] Not limited to Figures 4 to 6 In the case shown, the projection system or projection device 1 according to the present invention can also use other interior parts of the vehicle, such as the roof, seats and vehicle floor, as projection screens. Not limited to this, in the projection device 1 and projection system according to the present invention, the front and rear windshields or the side windows can also be used as projection areas to project images.

[0058] Figure 7 A preferred projection method of the projection system for a vehicle according to the invention is shown, wherein an expandable sun visor is used as a projection screen. Figure 5 In the case shown, the vehicle occupant H lying down on the seat 10 uses the folded sun visor 11 as a projection screen to view the image, and the projection device 1 projects the image onto the sun visor 11 at an oblique upward projection angle. Figure 5 The difference in the situation shown is that in order to allow the vehicle occupant H to see a larger projected image, Figure 7 The sun visor 11 in the Figure 5 The area of ​​the sun visor 11 is significantly increased. The original length and / or width of the sun visor can be extended here to obtain a larger projection area.

[0059] like Figure 7 As shown in the example, the sun visor 11 may include, for example, a main sun visor 11a and an auxiliary sun visor 11b for extension, wherein the auxiliary sun visor 11b can be connected to the main sun visor 11a so that the auxiliary sun visor 11b can be coplanar with the main sun visor 11a in the extended state. However, it is also conceivable to provide a telescopic bracket that can be extended and retracted relative to the periphery of the frame of the sun visor 11 on or in the sun visor, and a curtain that is particularly elastically tensioned on the telescopic bracket. As a result, the projection area that can be provided by the sun visor can be changed by operating the telescopic bracket to extend and retract. Here, the curtain for increasing the area can be stored or rolled up on the side of the sun visor facing away from the vehicle occupants, for example.

[0060] Figure 8 A sun visor used in a projection system for a vehicle according to the present invention is shown, wherein the sun visor 11 with an expandable area comprises a main sun visor 11a and an auxiliary sun visor 11b which are hingedly connected. Figure 8 The main sun visor 11a and the auxiliary sun visor 11b are shown in a state where they are folded together, and the entire sun visor 11 has the same size as a common sun visor. Figure 8The exposed surface is the side facing the vehicle occupants when the sun visor 11 is in the sunshade state. A sun visor fastener 13 is used to fix the sun visor 11 to the roof. A hook is provided at one end of the sun visor 11 opposite to the sun visor fastener 13 along the length direction of the sun visor 11, and the hook can be used to hang the sun visor 11 on a hook provided on the roof. Figure 8 In the embodiment shown, the auxiliary sun visor 11b is hingedly connected to the main sun visor 11a by a hinge 15, and the hinge 15 can be fixed in an open state of 180°, so that the auxiliary sun visor 11b is coplanar with the main sun visor 11a and together forms a Figure 7 Projection plane showing an enlarged area.

[0061] Fig. 9 A preferred sun visor 11 used in a projection system for a vehicle according to the present invention is shown, wherein the sun visor 11 with an expandable area includes a main sun visor 11a and an auxiliary sun visor 11b that are softly connected, such as by fabric or soft material. Magnets 16 that can attract each other are correspondingly arranged on the circumferential edges of the main sun visor 11a and the auxiliary sun visor 11b. For this purpose, slots 17 are correspondingly provided on the circumferential edges of the main sun visor 11a and the auxiliary sun visor 11b, and each slot can accommodate one of the magnets. In the expanded state of the auxiliary sun visor 11b, that is, when the auxiliary sun visor 11b is turned 180° from the position shown in the figure with respect to the current lower edge of the sun visor 11, the magnets 16 accommodated in the slots 17 are tightly attracted to each other, so that the auxiliary sun visor 11b is coplanar with the main sun visor 11a.

[0062] Fig.10 Show Figure 8 and 9 The schematic diagram of the sun visor 11 in the extended state is shown in FIG. Here, the auxiliary sun visor 11b is coplanar with the main sun visor 11a and thus provides a projection plane with an enlarged area. Fig.10 The side facing upward is the side facing the vehicle occupant H in the expanded state, and it is particularly advantageous to cover this side with a curtain material to make the brightness of the projected image uniform and the image quality clear. Fig.10 In order to distinguish the auxiliary sun visor 11b from the main sun visor 11a, a linear connection portion therebetween is marked, but ideally, in the expanded state, there are no detectable wrinkles or folds between the auxiliary sun visor 11b and the main sun visor 11a, thereby providing a good visual effect for the vehicle occupant H.

[0063] Fig.11a , Fig.11b and Fig.11c Shown separately Figures 8 to 10 Schematic diagram of the sun visor in the folded state, sun shading state and extended state. Fig.11aIn the folded state shown, the sun visor 11 is folded to a position that fits on the roof 18, and the main sun visor 11a and the auxiliary sun visor 11b are folded together, and the entire sun visor 11 has approximately the same size as a common sun visor. Fig.11b In the sunshade state shown, the sunshade 11 is flipped downward from the position where it fits the canopy 18, and the main sunshade 11a and the auxiliary sunshade 11b are still folded with each other, so that the sunshade area of ​​the sunshade 11 is equal to the sunshade area of ​​a common sunshade. Fig.11c In the extended state shown, the main sun visor 11a and the auxiliary sun visor 11b are coplanar with each other and together form a flat projection plane, which can be approximately twice the size of the shading area, for example about 300mm*300mm, in particular 320mm*300mm, 300mm*360mm or 320mm*360mm.

[0064] Further advantageously, Fig.11a , Fig.11b and Fig.11c The state transition shown in FIG. 1 can be automatically performed by means of an electric motor, thereby eliminating the need for manual adjustment by the vehicle occupant H.

[0065] Fig.12 The projection device according to the invention is shown in FIG. Fig.10 and Fig.11c Here, the sun visor 11 is in an extended state, and the projection device 1 arranged on the same side of the vehicle projects the image onto the extended projection plane of the sun visor 11 to achieve a larger display area. Fig.12 It can also be seen that the projection device 1 is relatively close to the sun visor 11. Based on this, the projection device 1 can achieve a good projection effect on such a sun visor 11 and the image deformation and distortion is relatively small, which further helps the vehicle occupants in such a situation. Figure 7 The ultimate visual enjoyment in the comfortable lying posture shown enhances the vehicle's driving experience.

[0066] from Fig.12 It can also be seen that the expanded projection plane does not have to extend strictly along the vertical direction, but can be directly facing the sight direction of the vehicle occupant H at a certain angle relative to the vertical direction.

[0067] In addition to the connection method described above for the sun visor 11, it is also possible to consider forming a slide guide structure on the main sun visor or the auxiliary sun visor. In particular, the main sun visor and the auxiliary sun visor can be constructed to overlap or accommodate each other. The vehicle occupant can unfold each auxiliary sun visor and make it coplanar with each other by pulling.

[0068] Not limited to Figures 8 to 12As shown, the sun visor 11 according to the present invention can also include a plurality of auxiliary sun visors for expansion, and other sun visors among the plurality of auxiliary sun visors can be further connected below the auxiliary sun visor 11b shown, or the area of ​​the sun visor 11 can be further expanded from the left side of the main sun visor 11a and the auxiliary sun visor 11b shown.

[0069] Fig.13 A schematic diagram of a flip screen 19 used in the projection system for a vehicle according to the present invention is shown in a stowed state.
