  In FIG. 1, reference numeral 1 denotes an instrument panel, which is used for a left handle in the embodiment. In FIG. 1, reference numeral 2 denotes a center console that extends in the front-rear direction and is connected to the instrument panel 1. The center console 2 is equipped with a shift lever 3 and the like.

  In the rear portion of the instrument panel 1, an emergency call device (control unit) 10 to be described later is disposed in the vicinity of the substantially central portion in the vehicle width direction. In the instrument panel 1, a telephone antenna 11, a satellite reception antenna 12, and a speaker 13 are disposed as accessory devices connected to the emergency call device 10. As an accessory device of the emergency call device 10, in addition to the above, a microphone (not shown) is provided near the rearview mirror in the vehicle interior ceiling. When a vehicle collision accident occurs, the emergency notification device 10 receives a collision detection signal, automatically notifies the service center outside the vehicle, notifies the service center of the position of the vehicle, and And a service center (communication) can be performed.

  The instrument panel 1 is equipped with audio speakers 21 to 25 and a GPS antenna 26 for a navigation device, in addition to the accessories of the emergency call device 10.

  In the instrument panel 1, a relatively large opening 5 is formed at a substantially central portion in the vehicle width direction. The opening 5 is used for mounting a vehicle-mounted device (not shown). For example, a navigation device (display thereof) is mounted. The opening area of the opening 5 is a size that allows the operator's arm to be inserted with a margin, and also serves as a service hole that can easily access the emergency call device 10 covered by the instrument panel 1. ing.

  Next, the arrangement | positioning position etc. of the emergency call apparatus 10 are demonstrated, referring FIGS. First, reference numeral 30 in the figure denotes an instrument panel support member (also referred to as a steering support member) extending in the vehicle width direction, which is a pipe-shaped strength member. The instrument panel support member 30 connects a pair of left and right front hinge pillars (not shown) constituting a vehicle body strength member (not shown). The instrument panel 1, a steering holding member (not shown), and the like are attached (supported) to the instrument panel support member 30. The instrument panel support member 30 has a substantially central portion in the vehicle width direction coupled to a tunnel portion 32 formed on the floor panel via a center stay 31 extending in the vertical direction.

  In the figure, reference numeral 40 denotes a brake pedal. The brake pedal 40 is held by a pin 43 so as to be swingable in the front-rear direction with respect to a bracket 42 fixed to a dash panel 41 (see FIG. 2) that partitions the engine room and the vehicle compartment. The upper end portion 40a of the brake pedal 40 extends upward from the bracket 42 and serves as an abutting portion with respect to a retreat prevention bracket described later. The brake pedal 40 is detached from the bracket 42 when a large external force is applied to the upper end portion 40a of the brake pedal 40. For example, a portion of the bracket 42 located at the lower end of the pin 43 is a weakened portion (for example, a notch), and the brake pedal 40 can be removed during a frontal collision (such a dropout). A variety of mechanisms have been known for a long time).

  In order to drop off the brake pedal 40 at the time of a frontal collision, the instrument panel support member 30 is integrated with an anti-retraction bracket 50 serving as a strength member. The retreat prevention bracket 50 extends forward from the instrument panel support member 30, and a tip portion thereof is positioned immediately behind the upper end portion 40 a of the brake pedal 40. As a result, when the brake pedal 40 is retracted at the time of a front collision, the upper end portion 40a abuts against the retraction preventing bracket 50, and the brake pedal 40 is dropped.

  The emergency notification device 10 is attached to the retreat prevention bracket 50 via the attachment bracket 60. The front end of the mounting bracket 60 is detachably fixed to the upper surface of the front end of the retraction preventing bracket 50 by a fixture 61 (in the embodiment, a bolt 61a and a nut 61b, see FIGS. 6 and 7).

  The mounting bracket 60 extends from the rear portion of the front end portion upward and then extends rearward, and is attached to the receding prevention bracket 50 in a cantilever manner. The emergency call device 10 is detachably fixed to the upper surface of the rear end portion of the mounting bracket 60 by a fixture. The emergency call device 10 has a battery 11 detachably held on its upper surface. The battery 11 is a periodic (for example, every 3 to 4 years) replacement object.

  As shown in FIG. 4, the emergency call device 10 attached to the retreat prevention bracket 50 via the attachment bracket 60 is covered by the instrument panel 1 from the front, upper side and rear side. The emergency notification device 10 covered by the instrument panel 1 can be accessed from the outside through the opening 5, and the emergency notification device 10 for replacing the battery 11 can be attached and detached through the opening 5. It is possible to do.

  Here, the details of the fixing portion between the retreat prevention bracket 50 and the mounting bracket 60 will be described with reference to FIGS. 3 and 5 to 7. First, the mounting plate 51 is fixed to the upper surface of the front end portion of the retreat prevention bracket 50 by welding or the like. The mounting plate 51 forms a pair of left and right slide holes 52 in cooperation with the retreat prevention bracket 50. The slide hole 52 is opened forward.

  On the other hand, as shown in FIG. 7 in particular, the front end portion of the mounting bracket 60 includes a flat plate-like central plate portion 60a, a pair of left and right vertical wall portions 60b that extend short from the left and right end portions of the central portion 60a, and each vertical portion. It has a pair of left and right flat plate portions 60c extending from the lower end of the wall portion 60b toward the outer side in the vehicle width direction. The vertical length of the vertical wall portion 60 b is set to be slightly larger than the thickness of the mounting plate 51.

  When attaching the attachment bracket 60 to the attachment plate 51, first, the vertical wall portion 60 b is inserted into the slide hole 52 of the attachment plate 51 while being slid. A cross-sectional view in this inserted state is shown in FIG. The vertical wall portion 60 b is fixed by the fixing tool 61 in a state where the vertical wall portion 60 b is inserted deeply into the slide hole 52. That is, the central plate portion 60a is positioned above the mounting plate 51, and the left and right plate portions 60c are positioned below the mounting plate 51 (see particularly FIG. 7). 6 and 7, a bolt constituting the fixture 61 is indicated by reference numeral 61a, and a nut screwed to the bolt is indicated by reference numeral 61b. In addition, although many holes are formed in the mounting plate 51, in the embodiment, the mounting holes into which the bolts 61a are inserted are two left and right positions indicated by reference numeral 53.

  Here, in a state where the vertical wall portion 60b is inserted deeply into the slide hole 52, even if the mounting bracket 60 is directed downward (upside down in FIG. 6), the mounting is performed. The bracket 60 is held by the retreat prevention bracket 50. In the embodiment, the attachment bracket 60 is attached to the attachment plate 51 in a state where the emergency call device 10 is fixed in advance. The mounting of the mounting bracket 60 to the mounting plate 51 (fixing by the fixing tool 61) is performed in an upside down state (upside down in FIG. 7) with the mounting bracket 60 facing downward from the viewpoint of ease of mounting work. It is done.

  When the battery 11 of the emergency call device 10 is replaced, the opening 5 is in an open state (removal of the in-vehicle device that is covered). Thereafter, the fixture 61 is accessed from below the instrument panel 1 and the fixing of the mounting bracket 60 to the retreat prevention bracket 50 is released. Thereafter, the emergency call device 10 is accessed through the opening 5 and is slightly displaced forward while gripping the emergency call device 10 to disengage the mounting bracket 60 from the mounting plate 51 (vertical wall). Escape from slide hole 52 of part 60b). Thereafter, the emergency call device 10 is taken out together with the mounting bracket 60 through the opening 5, and the battery 11 is replaced. After the battery 11 is replaced, the emergency call device 10 (mounting bracket 60) is fixed to the retreat prevention bracket 50 again by a procedure reverse to the above procedure.

  When the dash panel 41, that is, the brake pedal 40 is retracted at the time of a frontal collision, the brake pedal 40 comes into contact with the retraction preventing bracket 50 and is dropped to protect the occupant's knee or the vicinity thereof. Since the emergency call device 10 is located behind the front end of the retreat prevention bracket 50, it is possible to prevent a large external force acting from the front to the back during a front collision and to make an emergency call reliably. . If the emergency call device 10 is retracted, the emergency call device 10 is positioned above the retraction prevention bracket 50 and the instrument panel support member 30, so that the emergency call device 10 may come into contact with the occupant's knee or the vicinity thereof. Is prevented.

  Since the emergency call device 10 is attached to the retreat prevention bracket 50 via the mounting bracket 60, the impact at the time of a forward collision is mitigated by the mounting bracket 60, and the emergency call device 10 is more effectively protected. Become. In particular, since the mounting bracket 60 is attached to the retreat prevention bracket 50 in a cantilever manner, the impact mitigating action of the mounting bracket 60 is large. Moreover, since the mounting bracket 60 is fixed to the retreat prevention bracket 50 at a position ahead of the emergency call device 10, that is, when the fixed portion that is a strength portion is positioned in front of the emergency call device 10, Further protection of the emergency call device 10 is ensured.

  Although the embodiments have been described above, the present invention is not limited to the embodiments, and appropriate modifications can be made within the scope of the claims. If the emergency call device 10 is in the vicinity of the retreat prevention bracket 50, the emergency call device 10 may be positioned below or on the left and right sides. However, in order to prevent the emergency call device 10 from retreating near the occupant's (driver's) knee at the time of a frontal collision, the rear-rear bracket 50 (or the instrument panel support member 30) or the rear seat blower 50 and 50 are preferably arranged on the side farther in the vehicle width direction from the vicinity of the occupant's knee. In addition to the front end portion, the fixing portion of the mounting bracket 60 to the retreat prevention bracket 50 may be performed at a plurality of locations that are greatly separated from each other, such as the side end portion and the rear end portion. The emergency call device 10 may be directly fixed to the retreat prevention bracket 50 without using the mounting bracket 60. The emergency call device 10 may be fixed to the instrument panel support member 30 instead of the retreat prevention bracket 50 (for example, mounting via a bracket corresponding to the mounting bracket 60 is preferable). Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.

  The present invention is preferable for reliably operating the emergency call device in the event of a vehicle collision.
