  Next, the cover member according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments. In the embodiment, the direction of the cover member is designated by the mounting posture to the vehicle, the partition wall side is the front side, and the instrument panel side is the rear side.

  As shown in FIG. 4, the cover member 20 includes a lower end portion of the instrument panel 10 installed facing the passenger compartment 14 and a dash panel (partition wall) 12 installed on the front side of the instrument panel 10. It is attached so as to close the gap. As shown in FIG. 1, the cover member 20 of the embodiment includes a plate-shaped main body 22, an abutting portion 24 provided at an end of the main body 22 on the dash panel 12 side, and the abutting portion 24. The slit 26 is basically composed of the slit 26.

  The cover member 20 is made of a non-woven fabric, a synthetic resin plate, or a combination thereof, and the body portion 22 and the contact portion 24 are integrally formed. As a manufacturing method of the cover member 20, for example, injection molding or the like is adopted for a synthetic resin plate material, and hot press molding or the like is adopted for a non-woven fabric. The main body 22 is a plate-like portion constituting most of the cover member 20, and an opening 22a in which an air outlet for a foot of an occupant of the air conditioner is disposed is provided as necessary (see FIG. 1). ). Further, in the main body portion 22 of the embodiment, a plurality of attachment holes 22b for attachment to the instrument panel 10 are opened at the end on the instrument panel 10 side so as to be separated in the vehicle width direction.

  The abutting portion 24 is formed at an end portion of the main body portion 22 opposite to the dash panel 12 so as to abut on the floor carpet 12a constituting the passenger compartment 14 side of the dash panel 12 when the cover member 20 is attached. (See FIG. 4). The contact portion 24 is configured to be elastically deformable in the abutting direction against the floor carpet 12a. The contact portion 24 is bent at least at a connection portion with the main body portion 22 so that the contact surface with the floor carpet 12 a extends in a direction intersecting with the extending surface of the main body portion 22. Further, the contact portion 24 is formed by bending so as to define a space 24a that allows bending of the contact surface between the connection portion with the main body portion 22 and the contact surface with the floor carpet 12a. The contact part 24 of the example is formed in a U-shaped cross section in which the inner space 16 side between the instrument panel 10 and the dash panel 12 is convex and the passenger compartment 14 side is concave (see FIG. 2 or 3). The cover member 20 is dimensioned so that the abutting portion 24 interferes with the floor carpet 12a when the end on the instrument panel 10 side is attached to the instrument panel 10, and the abutting portion 24 bends the interference. It is configured so as to absorb. The contact portion 24 has a flat surface that contacts the floor carpet 12a.

  The contact portion 24 is provided with a plurality of slits 26. The slit 26 is formed so as to penetrate in the thickness direction of the contact portion 24. The slit 26 may be formed by a cutting means such as a laser or a cutter (for example, Thomson blade) after the contact portion 24 is formed, or may be formed at the same time as the contact portion 24 is formed. The plurality of slits 26 are provided in parallel and spaced apart from each other in a direction along the contact side of the contact portion 24 to the floor carpet 12a (see FIG. 1). That is, each slit 26 is formed so as to extend in a direction intersecting with a contact side of the contact portion 24 to the floor carpet 12a (abutting direction of the contact portion 24 to the floor carpet 12a). The slits 26 of the embodiment are formed from the tip of the contact part 24 to the connection part between the contact part 24 and the main body part 22, and the interval between the adjacent slits 26 is set to about 2 mm. The contact portion 24 is divided into a plurality of contact pieces 25 arranged in the direction along the contact side by the slit 26, and the contact pieces 25 formed between the adjacent slits 26 are flexibly deformed independently of each other. It is possible.

  The cover member 20 is attached by aligning the end of the main body 22 on the instrument panel 10 side with the lower end of the instrument panel 10 and fitting attachment means such as a push rivet into the attachment hole 22b. Moreover, the cover member 20 has closed | closed between the dash panel 12 and the lower end part of the instrument panel 10 because the contact part 24 contact | abuts elastically with the floor carpet 12a (refer FIG. 4).

  The cover member 20 is configured such that the contact portion 24 is elastically contacted with the floor carpet 12a. The cover member 20 is set so that the contact portion 24 slightly interferes with the floor carpet 12 a when attached to the instrument panel 10, and the contact surface of the contact portion 24 is connected to the main body portion 22. It is elastically deformed into a bent state. In this way, the cover member 20 is configured so that the contact portion 24 can be protected against unevenness of the floor carpet 12a, attachment between related members such as the dash panel 12 and the instrument panel 10 or a dimensional error due to deformation of the contact portion 24. By deforming and following, the gap between the floor carpet 12a and the instrument panel 10 can be closed. Further, the cover member 20 can absorb a displacement caused by vibration or the like when the vehicle travels as the contact portion 24 is deformed, and maintains a state in which the gap between the floor carpet 12a and the instrument panel 10 is closed. be able to.

  The contact portion 24 can be deformed independently of each other by the contact pieces 25 divided by the slits 26, and is deformed according to the unevenness of the floor carpet 12a in units of the contact pieces 25 when attached to the vehicle. The floor carpet 12a is excellent in following the unevenness. Here, since the slit 26 is provided from the tip of the contact portion 24 to the connection portion with the main body portion 22, each contact piece 25 is easily deformed independently. Further, since the cover member 20 has a different degree of deformation of the contact piece 25 according to the unevenness of the floor carpet 12a, and the contact piece 25 is caught by the unevenness of the floor carpet 12a, the contact portion is also affected by vibrations or the like during traveling of the vehicle. 24 is difficult to be displaced. Further, when the cover member 20 comes into contact with the floor carpet 12a made of fiber or the floor carpet 12a raised on the surface, the contact portion 24 is not easily displaced even when the fiber or hair is caught in the slit 26. Become. Thus, the shielding performance of the cover member 20 can be improved by providing the slit 26 in the contact portion 24.

  The cover member 20 is configured such that the individual contact pieces 25 divided by the slits 26 can be elastically deformed, so that it is possible to avoid applying a force to a specific portion of the contact portion 24 in an uneven manner. A force is applied to the contact piece 25 evenly. Therefore, the cover member 20 is difficult to sag the contact portion 24 and can suppress a change in the contact state of the contact portion 24 due to secular change. As described above, the cover member 20 can close the space between the dash panel 12 and the instrument panel 10 without any gap, so that the temperature-controlled air from the passenger compartment 14 can hardly escape to the internal space 16 side. The air conditioning efficiency of the passenger compartment 14 can be improved. Moreover, since the cover member 20 can block | close between the dash panel 12 and the instrument panel 10 without a clearance gap, it can improve a soundproofing effect.

  Since the contact portion 24 is formed in a U-shaped cross section in which a space 24a is defined between a connection portion with the main body portion 22 and the contact surface, the contact portion 24 is deformed under contact with the floor carpet 12a. It is easy to do. Moreover, since the contact portion 24 is open on the contact surface opposite to the floor carpet 12a, deformation of the contact surface is allowed by the space 24a. That is, according to the contact part 24 of an Example, the followable | trackability with respect to the floor carpet 12a can be improved more, and the shielding effect of the cover member 20 increases. In addition, the abutting portion 24 having an inverted U-shaped cross section abuts against the floor carpet 12a so that the convex portion is on the inner space 16 side. It is possible to prevent deviation.

The frame portion 42 is provided at the connection portion of the main body portion 22 with the contact portion 24 so as to extend along the contact side of the corresponding contact portion 24, thereby connecting the contact portion 24 and the main body portion 22. Bending can be suppressed. The cover member 40 can preferentially express the deformation of the contact portion 24 itself by suppressing the deformation at the connecting portion between the contact portion 24 and the main body portion 22, and elastic deformation of the contact portion 24. Thus, it is possible to enjoy an appropriate contact state with respect to the floor carpet 12a described above. Note that a frame portion may be provided on the contact portion 24.
(3) As shown in FIG. 7, the cover member 40 of the modified example is formed so that the frame portion 42 is thinner than the general portion and the inner space 16 side is recessed, but the passenger compartment side is recessed. Also good. In addition to the configuration in which the frame portion is recessed on one side, a configuration in which the frame portion recessed on the inner space side and the frame portion recessed on the passenger compartment side may be mixed.
(4) In the modified example, the frame portion is formed in a grid pattern in the main body portion, but the present invention is not limited to this, and a configuration in which the frame portion is formed only in the front-rear direction, a shape in which circles or polygons are continuous, and the like Good.
(5) In the modified example, the sound absorbing layer L1 is disposed on the inner space 16 side between the dash panel 12 and the instrument panel 10, and the compression layer L2 is disposed on the passenger compartment 14 side (see FIG. 7). A compression layer may be disposed on the inner space side.
(6) In the embodiment and the modified example, the contact formed by bending so as to define a space allowing the bending of the contact surface between the connection portion with the main body and the contact surface with the floor carpet. The part is configured so that the convex part is on the internal space side (the open end of the space is on the passenger compartment side), but the convex part is configured on the passenger room side (the open end of the space is on the internal space side). Also good. Further, the cover member may be provided with a mixture of a contact portion with a convex portion facing the inner space and a contact portion with a convex portion facing the passenger compartment.
