  By the way, an instrument panel in front of a passenger seat may be provided with an opening for inspection of a vehicle-mounted device inside (front) of the instrument panel, and a cover for closing the opening may be attached. In this case, if the four corners of the cover are fastened to the instrument panel side and firmly fixed like the undercover described in Patent Document 1 above, the vehicle-mounted device is moved backward at the time of a collision of the vehicle and In the event of a collision, stress may concentrate on a predetermined position of the cover and the cover may be broken (broken), and the sharp edge of the broken cover may face the passenger seat. On the other hand, when the cover is locked to the instrument panel side with a clip or the like so as to be able to be detached from the instrument panel side in order to avoid concentration of stress on the cover when a load from the front is input to the cover, vehicle collision At the same time, when the vehicle-mounted device moves backward and collides with the cover, the cover may come off the instrument panel side and fly backward, and may collide with an occupant seated in the passenger seat.

  Then, this invention aims at provision of the cover fixing structure which can suppress the damage of the passenger | crew who seats at a front passenger seat at the time of the collision of a vehicle.

  In order to solve the above-mentioned subject, the 1st mode of the present invention covers the opening which was provided in the instrument panel in front of the passenger seat of the vehicle to the cover which has the edge in the upper and lower sides and the left and right A cover fixing structure for fixing, comprising fixing means and locking means. The fixing means fixes any one of the upper, lower, left, and right edges of the cover to the vehicle body side of the peripheral edge of the opening, and when the cover receives a load from the front to the rear, the one edge The fixed state of the part is maintained to restrict the detachment of the one edge from the vehicle body side. The locking means locks at least one of the edges of the cover other than the one edge to the vehicle body side of the peripheral edge of the opening, and the cover receives a load from the front to the rear At the same time, the rear end of the vehicle body side is removed to allow the other edge to move rearward.

  In the above configuration, the fixing means (for example, the fixing means for fastening and fixing with bolts) fixes any one of the upper, lower, left, and right edges of the cover to the vehicle side of the peripheral edge of the opening, and the cover is front When receiving a load from the rear to the rear, the fixed state of the one edge is maintained, and the detachment of the one edge from the vehicle body side is restricted. In addition, the locking means (for example, the locking means for locking by the clip) engages at least one edge of the other edges of the cover other than the one edge with the vehicle side of the peripheral edge of the opening. When the cover receives a load from the front to the rear, the cover is removed from the vehicle body to the rear to allow the other edge to move rearward. Therefore, when an on-vehicle apparatus (for example, an air conditioner unit) disposed in front of the cover moves backward upon collision of the vehicle and collides with the cover, and the cover receives a load from the front to the rear from the on-vehicle apparatus When the cover is fixed to the vehicle body side without the one edge (hereinafter referred to as a fixed edge) side fixed by the fixing means being detached from the vehicle body side, the locking means is released rearward from the vehicle body side. The other edge side than the fixed edge tilts rearward with the fixed edge side as an axis.

  As described above, even if the cover receives a load rearward from the in-vehicle apparatus or the like at the time of a collision of the vehicle, the fixing means maintains the fixing state of the fixing edge relative to the vehicle body and the cover does not completely detach from the vehicle body side. Can be prevented from flying backward, and damage to the passenger on the passenger seat due to a collision with the cover completely removed from the vehicle body side can be suppressed.

  In addition, when the cover receives a load rearward from the in-vehicle apparatus or the like at the time of a collision of the vehicle, the locking means comes off from the vehicle body side to the rear and allows the other edge to move rearward. The concentration of stress from the device or the like to the cover can be avoided, and breakage (breaking) of the cover can be prevented. As a result, it is possible to prevent the pointed edge of the broken cover from being directed to the front passenger seat side, so it is possible to suppress the damage to the passenger seated on the front passenger seat.

  A second aspect of the present invention is the cover fixing structure according to the first aspect, wherein an in-vehicle device is disposed in front of the opening of the instrument panel. The cover has a proximity area in which the distance in the front-rear direction to the in-vehicle apparatus is the shortest. One edge fixed by the fixing means is an edge located at a position most distant from the proximity region among the upper, lower, left and right edges of the cover.

  In the above configuration, the in-vehicle device is disposed in front of the opening of the instrument panel, and the cover has the proximity region in which the distance in the front-rear direction to the in-vehicle device is the shortest. For this reason, when the on-vehicle device moves rearward and collides with the cover at the time of a collision of the vehicle, the in-vehicle device collides with the close region of the cover. And since the edge arranged at the position most distant from the proximity region among the upper, lower, left and right edges of the cover is fixed by the fixing means, the tilt angle of the cover tilting around the fixed edge can be suppressed. The amount of backward movement of the edge opposite to the fixed edge can be reduced. As a result, the amount of movement of the cover to the passenger side of the passenger seat can be reduced, and therefore, the living space ahead of the passenger of the passenger seat can be secured when the vehicle collides.

  A third aspect of the present invention is the cover fixing structure according to the first or second aspect, wherein the cover is formed longer in the vehicle width direction than in the vertical direction, and is fixed by the fixing means. One of the edges is one of the left and right edges of the cover.

  In the above configuration, one of the left and right edges of the cover elongated in the vehicle width direction (fixed edge) is fixed to the vehicle body by the fixing means. For example, in the case of a cover elongated in the vehicle width direction fixed to the instrument panel on the vehicle body side in front of the passenger seat, one of the upper and lower edges is fixed to the vehicle body side If one of the left and right edges is fixed to the vehicle body side, it is easier to secure a long distance between the collision position of the cover with the on-vehicle apparatus and the fixed end edge. For this reason, the tilt angle of the cover can be suppressed by securing a long distance between the collision point of the cover with the in-vehicle device and the fixed end edge, and the movement of the edge opposite to the fixed edge to the rear By reducing the amount, it is possible to secure a living space ahead of the passenger on the passenger seat at the time of a vehicle collision.

  A fourth aspect of the present invention is the cover fixing structure according to the third aspect, wherein the cover is a first cover disposed on the outer side in the vehicle width direction, and a first cover on the inner side in the vehicle width direction of the first cover. And a bracket disposed across the boundary between the first cover and the second cover and fixed to both the first cover and the second cover. . The bracket supports the first cover and the second cover, and prevents the cover from bending at the boundary when the cover receives a load from the front to the rear.

  In the above configuration, the cover includes a first cover on the outer side in the vehicle width direction and a second cover on the inner side in the vehicle width direction. As described above, since the cover is divided into the two covers (the first cover and the second cover), the workability of fixing the cover to the vehicle body, removing the cover for performing maintenance of the in-vehicle apparatus, etc. improves.

  In addition, the cover includes a bracket disposed across the boundary between the first cover and the second cover (hereinafter simply referred to as the boundary) and fixed to both the first cover and the second cover. . The bracket supports the first cover and the second cover, and prevents the cover from bending at the boundary when the cover receives a load from the front to the rear. Therefore, for example, when the on-vehicle device collides with the second cover in a state where the edge (fixed edge) of the first cover in the vehicle width direction outside is fixed to the vehicle side by the fixing means, the boundary portion is taken as an axis Tilting of only the second cover can be prevented, and the entire cover can be tilted about the fixed edge on the outer side in the vehicle width direction of the first cover. Thus, not only one cover but also the entire cover can be tilted, so that the tilt angle of the cover can be suppressed, and the amount of rearward movement of the edge opposite to the fixed edge can be suppressed. , The survival space ahead of the passenger on the passenger seat can be secured.

  In addition, since the bracket can prevent the cover from bending at the boundary portion, the entire cover is tilted about the fixed edge of the cover, and then the cover is further inclined rearwardly about the boundary portion. Can be prevented. For this reason, the amount of movement of the cover to the rear can be suppressed, and a living space ahead of the passenger on the passenger seat can be secured.

  According to the present disclosure, it is possible to suppress damage to a passenger seated in the front passenger seat at the time of a collision of a vehicle.

Therefore, since the cover 10 is not completely detached from the vehicle body 8 side, it is possible to prevent the cover 10 from flying backward, and the passenger of the passenger seat by the collision with the cover 10 completely detached from the vehicle body 8 side. Damage to the

  Also, when the cover 10 receives a load rearward from the air conditioner unit 3 at the time of a collision of the vehicle 1, the clips 20, 22 come back from the clip engagement holes 14, 33 on the vehicle body 8 side. Since the edge portions 11a and 12a, the lower end edge portions 11b and 12b, and the left end edge portion 12c are allowed to move rearward, concentration of stress from the instrument panel 2 to the cover 10 can be avoided. Damage (breakage) can be prevented. As a result, it is possible to prevent the pointed edge of the broken cover 10 from being directed to the front passenger seat side, so it is possible to suppress the damage to the passenger seated in the front passenger seat.

  Further, the right end of the cover 10 disposed at the position farthest from the proximity region 40 close to the protrusion 6 of the heater unit 3b among the upper end edge, the lower end edge, the left end edge and the right end edge of the cover 10 The edge (right end edge 11 d of the side cover 11) is fixed to the vehicle body 8 side of the peripheral portion 7 of the panel opening 4 of the instrument panel 2 by bolts 28 and 36. Therefore, as compared with the case where the end edge portion of the cover 10 at a position close to the projecting portion 6 of the heater unit 3b is fixed to the vehicle body 8 side, the cover 10 tilts with the right end edge 11d side as the axis. The angle can be suppressed, and the amount of rearward movement of the left end edge of the cover 10 can be suppressed. As a result, the amount of movement of the cover 10 to the passenger side of the passenger seat can be reduced, so that the living space ahead of the passenger of the passenger seat can be secured when the vehicle 1 collides.

Therefore, when the cover 10 receives a load rearward from the air conditioner unit 3 at the time of a collision of the vehicle 1, tilting of only the lower cover 12 with the boundary portion of the cover 10 as an axis can be prevented. It can be tilted. As described above, not only one cover (in the present embodiment, the lower cover 12) but the entire cover 10 can be tilted, so that the tilt angle of the cover 10 can be suppressed. By reducing the amount of movement to the front, it is possible to secure a living space in front of the passenger on the front passenger seat.

  In addition, since bending of the cover 10 at the boundary portion can be prevented by the bracket 13, the entire cover 10 tilts around the right end edge of the cover 10, and then the lower cover 12 is moved backward about the boundary portion. Further tilting can be prevented. Therefore, the amount of movement of the cover 10 to the rear can be suppressed, and a living space ahead of the passenger on the passenger seat can be secured.

  Therefore, according to the present embodiment, it is possible to suppress the damage to the occupant seated in the front passenger seat at the time of the collision of the vehicle 1.
