Description

  The present invention relates to a vehicle shielding member and a vehicle shielding structure for shielding a gap between a fixed portion and a movable portion in a vehicle.

  In a vehicle, for example, a blind member may be disposed in order to hide a gap between a steering column cover (movable part) and an instrument panel (fixed part) (see, for example, Patent Document 1). In many cases, a sheet-like material such as cloth is applied to such a blind member. When a wide range of gaps are hidden by the sheet-like blind member, the blind member is curved in part. The gap is covered with the portion (curved surface portion) formed.

However, in this conventional structure, stress concentrates on a part of the blind member during the tilt / telescopic operation, and wrinkles are likely to occur in the curved portion.

[First Embodiment]
A vehicle shielding member and a vehicle shielding structure according to a first embodiment of the present invention will be described with reference to the drawings. In the figure, the arrow UP indicates the upward direction of the vehicle, and the arrow FR indicates the forward direction of the vehicle.

  FIG. 1 shows the periphery of a steering column 14 disposed in front of the driver's seat of the vehicle. As shown in FIG. 1, an opening 12 (shown by a two-dot chain line) through which the steering column 14 is inserted is formed in the instrument panel 10 as a fixed portion in the vehicle in front of the driver's seat. . As shown in FIG. 2, the steering column 14 protrudes obliquely rearward on the vehicle from the inside of the instrument panel 10 to the outside. A circular steering shaft 16 is accommodated in the steering column 14, and the steering column 14 rotatably supports the steering shaft 16. A front end portion (a vehicle front side end portion) of the steering shaft 16 is disposed in an engine room (not shown) and is connected to a steering gear box (not shown). Further, the rear end portion of the steering shaft 16 protrudes from the rear end surface of the steering column 14 toward the vehicle rear side. A steering wheel 20 for changing the steering angle is fixed to the rear end portion of the steering shaft 16. Accordingly, when the occupant (driver) rotates the steering wheel 20, the steering shaft 16 is rotated by the same rotation amount in the same rotation direction.

  The entire circumference of the steering column 14 is covered with a column cover 18 having a substantially rectangular tube shape as a movable portion. The column cover 18 is made of resin, is fixed to the steering column 14, is not rotated by the rotation of the steering shaft 16, and is movable relative to the instrument panel 10 (arrow A). Direction and arrow B direction). The column cover 18 is configured by combining an upper column cover 18A on the upper side and a lower column cover 18B on the lower side. The lower side of the upper column cover 18A and the upper side of the lower column cover 18B are open, and the left and right sides of the upper column cover 18A and the left and right sides of the lower column cover 18B are connected vertically. The upper column cover 18A is shorter than the lower column cover 18B, and the front end portion of the upper column cover 18A is disposed at a position on the vehicle rear side compared to the front end portion of the lower column cover 18B. The front end portion of the upper column cover 18A is usually disposed at a position slightly away from the instrument panel 10. The front end of the lower column cover 18B is inserted inside the opening 12 of the instrument panel 10, and covers a long range below the steering column 14.

  As shown in FIG. 1, the upper column cover 18 </ b> A is an R-shaped curved portion 19 that is largely curved on both sides in the vehicle width direction from the viewpoint of design and the like. Almost corresponding to the curved portion 19 of the upper column cover 18A, both sides of the upper edge of the opening 12 in the instrument panel 10 are also R-shaped curved portions 13 that are largely curved from a design standpoint.

  The steering column 14 shown in FIG. 2 includes a tilt mechanism (not shown) and a telescopic mechanism (not shown). By the tilt mechanism, the steering column 14 can be swung in the vertical direction (arrow B direction) with the front end side as a fulcrum, and the steering angle of the steering wheel 20 is adjusted. It is possible. Further, the steering column 14 can be slid in the axial direction (arrow A direction) of the steering shaft 16 by the telescopic mechanism, and the front-rear direction position of the steering wheel 20 can be adjusted. As a result, the movable range of the steering column 14 and the column cover 18 is relatively large.

  Thus, since the movable range of the column cover 18 is relatively large, the gap 32 between the instrument panel 10 and the upper column cover 18A in the column cover 18 is also relatively large. In the gap 32 between the instrument panel 10 and the upper column cover 18A, a shielding cover 22 as a vehicle shielding member is disposed. The shielding cover 22 is an interior member for a vehicle and has flexibility. In the present embodiment, the shielding cover 22 has a structure in which PVC (vinyl chloride resin) and a woven fabric are laminated, and the front side (a surface visually recognized by an occupant) The material (texture) like leather is given out by PVC (vinyl chloride resin) constituting the side, and softness is given by the woven fabric constituting the back side and toughness is ensured.

  As shown in FIG. 1, the shielding cover 22 is a main body portion 24 that shields an internal unit in the instrument panel 10 by shielding a gap 32 between the instrument panel 10 and the upper column cover 18 </ b> A (column cover 18). And a free portion 26 as an extended portion extended to both sides of the main body 24 and a connecting portion 28 as a tension applying means for connecting the free portions 26 on both the left and right sides (both sides). Has been.

  The main body 24 has a substantially band shape, and a part of the upper side (one side) is an instrument panel side mounting portion 24A attached to the inside of the opening 12 of the instrument panel 10 by an adhesive, and the lower side ( A part of the other side) is a cover side attachment portion 24B attached to the front end portion side of the upper column cover 18A by an adhesive. The instrument panel side mounting portion 24A is the entire area of the shielding cover 22 that overlaps the instrument panel 10 on the vehicle lower side of a cut 30 described later, and the cover side mounting portion 24B is the upper column cover 18A of the shielding cover 22. And the whole area of the overlap. Thereby, the end of the upper edge side of the opening 12 in the instrument panel 10 and the end of the upper column cover 18 </ b> A are connected by the main body 24 in the shielding cover 22.

  As shown in FIG. 2, the main body 24 has a substantially U-shape that is expanded in a slack state when viewed from the side, and is curved so as to be recessed toward the front lower side of the vehicle. As shown in FIG. 1, when viewed from the front, the middle portion in the longitudinal direction is formed into a large-diameter (smooth) arc shape extending substantially in the vehicle width direction, and both side portions are the middle portions in the longitudinal direction. Compared to the above, it has an arc shape with a small diameter, and is greatly curved downward on the outside in the shielding cover width direction (arrow 22W direction). That is, the main body 24 forms a relatively horizontal surface portion near the cover side mounting portion 24B in the middle portion in the longitudinal direction, but in the both sides in the longitudinal direction, the shielding cover width direction (arrow 22W). The curved surface portion 24 </ b> C that is greatly convexly curved outward and obliquely upward is formed. Such a curved surface portion 24 </ b> C inevitably occurs when the main body portion 24 connects the bending portion 13 of the instrument panel 10 and the bending portion 19 of the upper column cover 18 </ b> A.

  The free part 26 is extended from both the instrument panel side mounting part 24 </ b> A and the cover side mounting part 24 </ b> B in the main body part 24 to both sides. In other words, the end portion on the instrument panel 10 side of the shielding cover 22 is not entirely bonded along the vehicle width direction, and the both ends in the vehicle width direction on the instrument panel 10 side are not bonded. It is in a state.

  In the upper part of the instrument panel side mounting part 24A in the main body part 24, the main body part 24 and the connecting part 28 are partitioned, and a cut line 30 that is substantially continuous in the vehicle width direction (a direction substantially along the upper edge part of the opening 12). Is formed, and the connecting portion 28 has a free string shape that is not bonded to the instrument panel 10. Here, in the present embodiment, the free portion 26 is set to be pulled slightly by the connecting portion 28 (this tension is indicated by F1 in the drawing). On the other hand, a tension F2 from the main body portion 24 side to the free portion 26 side is applied.

(Action / Effect)
Next, the operation and effect of the above embodiment will be described.

  Since the free part 26 is extended to both sides from between the instrument panel side mounting part 24A and the cover side mounting part 24B of the main body part 24 that shields the gap 32, so-called tilt operation or telescopic by a tilt mechanism (not shown). When the steering column 14 and the column cover 18 are moved due to a so-called telescopic operation by a mechanism (not shown), the stress generated in the main body portion 24 is absorbed by the free portion 26. In other words, the free portion 26 forms a relief path for stress generated in the main body portion 24.

  Here, in this embodiment, the free portion 26 is pulled by the connecting portion 28 (in the direction indicated by the tension F <b> 1), and the connecting portion 28 moves from the main body portion 24 side to the free portion 26 side with respect to the free portion 26. Therefore, when the column cover 18 moves (especially when the column cover 18 moves greatly), stress concentrated on the main body 24 (especially the curved surface 24C) is applied to the connecting portion 28 via the free portion 26. Escape and stress concentration can be avoided. In other words, a stress escape path provided in the direction of the tension F2 is formed by the connecting portion 28. As a result, generation of wrinkles in the main body portion 24 when the column cover 18 is moved can be effectively suppressed. Thus, the appearance of the main body 24 can be kept good.

  Further, since the free portions 26 are connected to each other by the connecting portion 28, the free portion 26 is unlikely to flutter when the column cover 18 is moved, and the free portion 26 can be prevented from protruding from the opening 12 of the instrument panel 10. .
