Which is as to control section 60. It is preferable that the moving speed setting of the sun visor body 32 in such an emergency is set to a higher speed than the (moving in / out) moving speed setting of the sun visor body 32 in a normal time (non-emergency).

  In the above configuration, the vehicle collision estimation device 80, the slide sun visor control ECU 70, and the drive mechanism 60 constitute a sun visor main body evacuation device 90 as a vehicle component evacuation device.

(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  While the vehicle is running with the sun visor main body 32 shown in FIG. 4 arranged at the extraction position 32Y (using the sun visor), the camera 78 shown in FIG. Is acquired, the image processing ECU 76 performs image processing on the acquired captured image to extract a preceding vehicle and an obstacle and output a signal to the collision determination unit 72A. At the same time, the millimeter wave radar 74 scans the front of the vehicle with radio waves, detects the preceding vehicle and obstacles, and outputs a signal to the collision determination unit 72A. Based on the input signals from the image processing ECU 76 and the millimeter wave radar 74, the collision determination unit 72A detects a collision (with a preceding vehicle or an obstacle) of the host vehicle and predicts a collision (determination that the possibility of a collision is high). Do at least one of the following.

  When the collision determination unit 72A (the vehicle collision estimation device 80) outputs at least one of the collision detection signal and the collision prediction signal to the webbing winding device 84A and the airbag control device 86A, the webbing winding device The webbing 84B is wound up by 84A, and the airbag 86B is inflated by the airbag control device 86A and deployed toward the front seat occupant P (see FIG. 5).

  Here, the slide sun visor control ECU 70 is at least partially based on an input signal of at least one of a collision detection input signal and a collision prediction input signal from the collision determination unit 72A (vehicle collision estimation device 80). The sun visor main body 32 disposed in the chamber 100 (for example, at the drawer position 32Y (see FIG. 4)) is inflated in the direction of the storage position 32X and at the time of or just before the collision of the vehicle 10, and the front seat occupant P (see FIG. 5), the drive mechanism 60 is controlled so as to move to a non-interfering position that does not interfere with the airbag 86B that is deployed to the side. Therefore, at the time of or just before the collision of the vehicle 10, at least as shown in FIG. The sun visor main body 32, which is partly disposed in the passenger compartment 100 at a position that interferes with the deployment locus of the airbag 86B (for example, at the pull-out position 32Y), The airbag 86B is retracted from a position where it can interfere with the airbag 86B (a position where the deployment operation of the airbag 86B can be hindered) toward the retracted position 32X on the back side of the molded ceiling 20, and the airbag 86B expands without interfering with the sun visor body 32. It can be normally deployed to the front seat occupant P (see FIG. 5) side.

(Supplementary explanation of the embodiment)
In the above-described embodiment, the case where the sun visor body retracting device 90 as the vehicle component retracting device retracts the sun visor body 32 as the vehicle component has been described. Used at a position that interferes with the deployment locus of the rear seat airbag that expands and deploys toward the rear seat occupant side at the time of or immediately before the collision, and at a position that does not interfere with the deployment locus of the airbag Other vehicle parts such as an accessory storage board (attached to the back of the seat back) that can move between the retracted position and the retracted position.

  In the above embodiment, as shown in FIG. 2, the vehicle collision estimation device 80 as emergency state recognition means is at least one of vehicle collision detection and collision prediction based on information from the millimeter wave radar 74 and the camera 78. The emergency state recognition means performs at least one of vehicle collision detection and collision prediction based on other information such as information by an acceleration sensor that detects vehicle deceleration, for example. May be.

  The emergency state recognition means receives at least one of vehicle collision information and collision prediction information by, for example, an ITS (Intelligent Transport System) which is an intelligent transportation system using information communication technology. Thus, other emergency state recognition means such as an emergency state recognition device capable of at least one of vehicle collision detection and collision prediction may be used.

  In the above embodiment, as an example, as shown in FIG. 4, the sun visor main body 32 in the fully pulled-out position 32 </ b> Y is placed at the storage position 32 </ b> X (see FIG. 3) at or just before the collision of the vehicle 10. The case where the vehicle is retracted in the direction has been described as an example. For example, the sun visor main body 32 located at an intermediate position (half-drawing position) between the extraction position 32Y and the storage position 32X is also stored at the time of the vehicle collision or immediately before the collision. It is retracted in the direction of the position 32X.

  Further, for example, the emergency state recognition means predicts the magnitude of the possibility of collision of the host vehicle at a plurality of determination levels based on a predetermined determination criterion, and the storage position of the sun visor body (vehicle component) according to the determination level ( The amount of movement in the direction of the retreat position may be set. As an example, the emergency state recognition means predicts the possibility of collision of the host vehicle at three classification levels of large, medium and small, and when the determination level is small, the movement amount is small, and when the determination level is medium It may be set such that the movement amount is medium and the movement amount is large when the determination level is large.

  Furthermore, in the said embodiment, as FIG. 3 shows, although the storage position 32X of the sun visor main body 32 is made into the storage chamber 22 of the vehicle ceiling part 12, the storage position of a sun visor main body is a vehicle ceiling part, for example. It is good also as another position like the predetermined position in this accommodation recessed part in the case of forming the storage recessed part opened toward the vehicle downward side in the shaping | molding ceiling (20).

  Furthermore, in the above embodiment, as shown in FIG. 1, the slide sun visor control ECU 70 is arranged in the vehicle ceiling 12 separately from the vehicle control ECU 72, but the drive control means is connected to the vehicle control ECU (72). It may be built in. In this case, the number of control ECUs can be reduced, and an empty space in the vehicle ceiling portion 12 is increased, so that the camera 78 can be easily mounted on the vehicle ceiling portion 12 side.

  In the above-described embodiment, the drive mechanism unit 60 does not interfere with the airbag 86B that is inflated and deployed toward the occupant P (see FIG. 5) at the time of or just before the collision of the vehicle 10 by the control of the slide sun visor control ECU 70. The sun visor main body 32 is moved to the non-interference position, and such a configuration is preferable. However, as the control by the drive control means, for example, the drive means moves the sun visor main body arranged in the passenger compartment toward the storage position. Even if the airbag is inflated and deployed to the occupant side during or immediately before the collision of the vehicle, the airbag will not interfere with the sun visor body. If the setting is such that a certain degree of interference is obtained, it can be established that substantially the same effect as in the above embodiment can be obtained.
