Description

  The present invention relates to an indoor structure of a vehicle in which a window is disposed on the side of an instrument panel, and more particularly to an indoor structure that improves the visibility of the window disposed on the side of the instrument panel.

  Conventionally, a front door window of an automobile has been provided with a triangular window in a portion adjacent to the front pillar or a mounting portion of a door mirror so that the front door window can be moved up and down while avoiding the hinge portion of the front door. Since these obstruct the field of view between the front window and the front door window, the triangular window of the front door is hardly adopted.

  On the other hand, for the purpose of expanding the indoor space and improving styling, the inclination of the front window is increased to expand the space on the upper surface of the instrument panel forward (see Patent Document 1). In such a vehicle, since the lower end of the front pillar protrudes greatly forward, a door mirror is attached to the front end of the front door window with a fixed glass (triangular window) behind the front pillar. The field of view is secured between the front pillar and the front pillar. However, the distance from the driver's seat occupant to the triangular window is large, and the blind spot of the field of view tends to increase under the window.

  In general, the blowout port of the window defroster on the side of the vehicle is often provided in the design surface such as the upper surface or the front surface of the instrument panel so as not to obstruct the view from the driver's seat. If the air is blown from the installation surface as it is, the window will not be blown efficiently, so a louver or the like is provided at the outlet to control the direction of the wind, but the shape of the outlet and the air flow path are complicated. It was easy to become. Furthermore, since the wind blown out from the installation surface is released into the open space immediately after the blowout, there is a possibility that the wind will diffuse without reaching the window glass even if the wind direction is controlled by the louver.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide an interior structure of a vehicle that can expand a view that can be seen from a window on the side of an instrument panel downward. is there. In addition, an object of the present invention is to provide an interior structure of a vehicle that can effectively guide the airflow of a defroster, improve the defogging performance for the window, and ensure the visibility from the window.

  In order to solve the above-described problems of the related art, the present invention provides an interior structure of a vehicle in which a window is arranged on a side of an instrument panel, between the window and a side end portion in the vehicle width direction of the instrument panel. A recessed portion that is recessed downward in the vehicle vertical direction from the upper surface of the instrument panel is provided, and the lower edge of the window is disposed along the bottom surface of the recessed portion.

  In the present invention, the window is a window located on the driver's seat side, and when an occupant of the driver's seat views the window, the upper surface side edge of the instrument panel substantially overlaps the lower edge of the window. Is preferred. Further, when the window is a window located on the passenger seat side, when an occupant of the driver's seat sees the window, the upper surface side edge of the instrument panel substantially overlaps the lower edge of the window. It is preferable that a passenger seat side upper surface side edge of the instrument panel is formed, and a passenger seat side and driver seat side upper surface side edge are formed symmetrically.

  Further, in the present invention, a defroster outlet is provided on the side end face of the instrument panel facing the recessed portion so as to face the window. It is preferable that the shape of the pillar surface located forward or backward in the vehicle front-rear direction of the recessed portion is inclined or curved in a direction of gradually narrowing the space of the recessed portion from the side end surface toward the window. It is.

  As described above, the present invention is an interior structure of a vehicle in which a window is disposed on the side of an instrument panel, and an upper surface of the instrument panel is disposed between the window and a side end portion in the vehicle width direction of the instrument panel. Since a recessed portion that is further recessed downward in the vertical direction of the vehicle is provided and the lower edge of the window is arranged along the bottom surface of the recessed portion, it is visible through the window extended downward by the recessed space. The field of view can be expanded downward.

  Further, in the aspect in which the window is located on the driver's seat side, and when the passenger in the driver's seat sees the window, the upper edge of the instrument panel substantially overlaps the lower edge of the window. The recessed portion on the side of the instrument panel is minimized, and the field of view that can be confirmed by the driver's occupant can be efficiently expanded downward. Further, the window is a window located on the passenger seat side, and when the driver sees the window, the upper surface side edge of the instrument panel substantially overlaps the lower edge of the window. In an aspect in which the passenger seat side upper surface side edge of the instrument panel is formed and the upper surface side edges of the passenger seat side and the driver seat side are formed symmetrically, the concave portion on the side of the instrument panel is The field of view on the passenger seat side, which can be minimized and can be confirmed by the passenger in the driver's seat, can be efficiently expanded downward.

  Since the blowout port of the defroster is provided on the side end face of the instrument panel facing the recessed portion so as to face the window, the airflow from the blowout port can be directly blown onto the window, and the shape of the blowout port and There is no need to complicate the structure, and it is possible to efficiently remove the fogging of the window with a simple outlet shape. In addition, since the airflow from the outlet is prevented by the space of the recessed portion and efficiently flows toward the window, it is possible to improve the defogging performance. Furthermore, the shape of the pillar surface located forward or backward in the vehicle front-rear direction of the recessed portion is inclined or curved in a direction of gradually narrowing the space of the recessed portion from the side end surface toward the window. In this case, the pillar surface functions as a guide for guiding the airflow from the outlet to the window, and the pillar surface flows toward the window more efficiently, so that the defogging performance can be further improved.

  Details of the embodiment of the present invention will be described below. FIG. 1 is a schematic view showing an instrument panel 1 in a vehicle compartment and its surroundings according to an embodiment of the present invention. In the figure, an A-pillar 2 constituting a part of the side of the vehicle body is disposed on the side of the instrument panel 1 in the vehicle width direction. The A pillar 2 covers the interior side of structural materials such as inner, reinforcement, and outer with trims (21, 22) made of a resin material or the like to form a design surface.

  As shown in FIG. 2, the A pillar 2 is widened downward from the roof side, branches into a front pillar 21 and an auxiliary pillar 22 on the way, and forms a triangular window 3 near the lower side of the A pillar 2. . The triangular window 3 is formed in a rectangular shape in which the lower side of the triangular window 3 (fixed glass 31) is expanded downward by a belt line 33 descending toward the front of the vehicle and a descending line 34 extending from the base of the front pillar 21 toward the rear of the vehicle. Along with this, the triangular window 3 has a substantially square shape. The fixed glass 31 is fixed to the A pillar 2 via a sealing material or the like so as to close the triangular window 3 from the outside of the vehicle compartment.

  As shown in FIGS. 3 and 7 (arrow A in FIG. 1), the side wall 12 stands at a certain distance from the fixed glass 31 at the vehicle width direction side end of the instrument panel 1. It is installed. The lower part of the front pillar 21 and the lower part of the auxiliary pillar 22 are both disposed between the fixed glass 31 and the side wall 12, and the lower ends of the fixed glass 31, the front pillar 21, the auxiliary pillar 22, and the side wall 12 are connected to the bottom surface 41. is doing. Thereby, a space 4 surrounded by the fixed glass 31, the front pillar 21, the auxiliary pillar 22, and the side wall 12 is formed on the side of the instrument panel 1. The space 4 has a shape in which the four sides and the bottom surface 41 are surrounded and the upper surface is opened, and is a recessed portion that is recessed below the upper surface 11 of the instrument panel 1 in the vehicle vertical direction.

  The lower end edge 32 of the triangular window 3 (the line where the fixed glass 31 and the bottom surface 41 abut) is also located below the edge 13 of the upper surface 11 of the instrument panel 1 in the vehicle vertical direction. Due to this feature, the triangular window 3 can be provided so as to extend below the upper surface 11 of the instrument panel 1 in the vehicle vertical direction, and the field of view on the lower side of the vehicle side can be enlarged.

  Furthermore, in this embodiment, when viewed from the driver's seat occupant, the lower end edge 32 of the triangular window 3 and the end edge 13 of the upper surface 11 of the instrument panel 1 appear to overlap each other as shown in FIG. is doing. Thereby, the lower end of the triangular window 3 can be lowered to the lowest position within the range in which the driver's occupant can see. The both ends of the lower end edge 32 may be slightly inclined upwards in design, or may have an arc shape. In that case, it is sufficient that the substantially straight portion at the center portion is seen to overlap the end edge 13. .

  As a method of making the above arrangement when viewed from the occupant of the driver's seat, for example, conditions such as a seat slide position and a backrest angle are set as design reference positions, and a 50th percentile adult male dummy A position in which a part of the edge 13 of the upper surface 11 of the instrument panel intersects or is close to a line connecting the center of the dummy head and the center of the lower edge 32 of the triangular window 3 while the seat is seated on the seat What is necessary is just to set to a relationship. However, the type of dummy and the position of the seat can be changed as appropriate according to the concept of each vehicle. The above setting can be applied to both sides of the vehicle. However, it is particularly preferable to apply the setting based on the passenger seat side, which is difficult to confirm far from the driver's seat, from the viewpoint of improving the visibility.

  The upper surface 11 of the instrument panel 1 has a limit in suppressing the height for the convenience of arranging an airbag and instruments. In the illustrated example, the height is suppressed by inclining the upper surface 11 of the instrument panel 1 excluding the instrument cluster portion toward the driver's seat. However, by providing concave portions (spaces 4) that are lowered downward on both side ends of the instrument panel 1 as in the present invention, the height of the upper surface 11 of the instrument panel 1 can be reduced without lowering the triangular window 3. The field of view can be expanded.

  Further, in the present invention, as shown in FIG. 3 (FIG. 7), a side wall 12 of the instrument panel 1 is erected so as to face the fixed glass 31 and a defroster for removing fogging of the window glass on the side wall 12 is provided. A blowout port 5 is provided. With this configuration, the side wall 12 only needs to be provided with a simple slit shape, and it is not necessary to provide a complicated louver shape for controlling the wind direction. For this reason, the wind from a defroster can be efficiently blown out toward the fixed glass 31, and cloudiness can be removed rapidly and a visual field can be ensured.

  Further, since the blowout port 5 is provided in the side wall 12 that forms the space 4 described above, the blown air stays in the space 4, and the blown air can be efficiently guided to the fixed glass 31. Furthermore, as shown in FIG. 4, the trim surface of the front pillar 21 or the auxiliary pillar 22 that forms the space 4 is inclined in the direction in which the space 4 narrows (or toward the fixed glass 31 from the side wall 12 of the instrument panel 1 (or The shape is curved. More specifically, after being narrowed at one end, a diffuser shape that is slightly enlarged just before the fixed glass 31 is formed, and the entire space forms a throat shape.

  With this configuration, the pillar surfaces (21, 22) have a function of a guide for guiding the wind blown into the space 4 from the blowout port 5 of the defroster toward the fixed glass 31, and the blown wind is directed to the fixed glass 31. Since it can be attracted efficiently, it is possible to remove the fogging of the fixed glass 31 more quickly and contribute to securing the sight of the occupant.

  In addition, in the said embodiment, although the case where the side window of the instrument panel 1 was the triangular window 3 by the fixed glass 31 was demonstrated, this invention is not limited to this, A pillar 2 is a front. The present invention can also be applied to a case in which only the pillar 21 is provided and the side window of the instrument panel is the door glass of the front door.

  As described above in detail, according to the present invention, the position of the lower edge of the window glass is lowered as much as possible to expand the field of view of the occupant from the driver's seat below the vehicle, and the arrangement of the outlet of the defroster. Rapid removal of fogging of the window glass can improve the occupant's visibility.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
