2. Description of the Related Art A conventional technique relating to an on-vehicle monitor supporting structure for supporting an on-vehicle monitor which is mainly viewed while seated in a rear seat is disclosed in Japanese Utility Model Laid-Open No. 58502/1993. The vehicle-mounted monitor support structure disclosed in this publication supports a vehicle-mounted monitor on the rear part of a console box arranged between seats which are arranged apart from each other on the left and right.

[0003]

By the way, when the in-vehicle monitor is arranged between the seats which are spaced apart from each other on the left and right in this way, in the unlikely event of a vehicle collision during running, at that time, Further, if the passenger in the center of the rear seat does not wear the seat belt, the passenger may move forward at the time of a collision and may collide with the monitor between the seats or the supporting portion thereof.

There is also a ceiling mount type in which a monitor is mounted on the roof of a vehicle. In this case, although the above-mentioned collision with the monitor or its support is eliminated,
Since the monitor is provided on the upper part, as a matter of course, it is necessary to look at the monitor while facing diagonally upward, and there is a problem that the viewer becomes tired. In addition, there is a problem that the cost increases to secure the strength of the supporting side.

Further, there is a device in which a monitor is embedded in the headrest of the front seat, but in this case as well, although the passenger in the center of the rear seat does not collide with the monitor or its supporting portion, a plurality of people in the rear seat can see it. However, there is a problem in that the monitors must be embedded in both the left and right headrests, which increases the cost.

Therefore, the present invention enables comfortable viewing and suppression of cost increase, and can absorb the collision energy even if a passenger collides with the monitor or its support. It is intended to provide an on-vehicle monitor support structure.

[0007]

In order to achieve the above object, an in-vehicle monitor support structure according to claim 1 of the present invention is a base portion attached to a vehicle body side (for example, a seat side attachment base portion 19 in the embodiment). ) Is rotatably connected to the base portion via a support shaft (for example, the swing support shaft 20 in the embodiment) and supports a monitor (for example, the monitor 60 in the embodiment) (for example, the embodiment). Swing support 15 and rotation support 1 in the form
6) and a guide groove (for example, the guide groove 28 in the embodiment) is formed in one of the base portion and the support portion, and the other portion of the base portion and the support portion is provided with the guide groove. A guide portion (for example, the guide pin 21 in the embodiment) that moves in the guide groove when the support portion rotates with respect to the base portion is provided, and further, a regulating plate that closes the guide groove in the guide groove (for example, in the embodiment). A regulation plate 30) is provided, and the movement of the guide portion in the guide groove is regulated by the regulation plate to regulate the rotation of the support portion with respect to the base portion, while between the base portion and the support portion. When a load equal to or more than a predetermined value is applied to the guide plate, the restricting plate is deformed or damaged by the guide part so that the support part rotates with respect to the base part. It is a symptom.

Accordingly, the movement of the guide portion within the guide groove is normally regulated by the regulation plate to regulate the rotation of the support portion with respect to the base portion, and in the unlikely event that a passenger collides with the monitor or the support portion. However, even if there is a load greater than a predetermined value between the base and support,
When the restriction plate is deformed or damaged by the guide portion, the support portion rotates with respect to the base portion and absorbs collision energy. Therefore, for example, by providing a monitor between both seats, it is possible to absorb the collision energy in the unlikely event of a collision with the monitor or the supporting portion while improving the viewing in the rear seat and suppressing the cost increase.

An in-vehicle monitor support structure according to a second aspect of the present invention relates to the on-vehicle monitor support structure according to the first aspect, wherein the base portion is a seat (for example, a driver's seat 11 and a seat in the embodiment, which is arranged left and right apart from each other. One of the passenger seats 12) (for example, the driver seat 11 in the embodiment) is attached to the other seat (for example, the passenger seat 12 in the embodiment), and the support shaft is provided. The axis is arranged in the direction from the one seat to the other seat.

As a result, an axis is arranged in the direction from one seat to the other seat on the base portion attached to the other seat side of either one of the seats which are separated from each other on the left and right. A support shaft is provided on the support shaft, and the monitor is supported on the support shaft via the support portion, so that the monitor can be provided between these seats. In addition, even if a passenger collides with the monitor or the supporting portion, a load greater than a predetermined value is applied between the base portion and the supporting portion, so that the regulation plate is deformed or damaged by the guide portion. The support part rotates about the support axis with respect to the base part and absorbs collision energy. Therefore, a monitor is provided between both seats to improve the viewing in the rear seat and suppress the cost increase, and it is possible to absorb the collision energy in the event of a collision with the monitor or the support.

The on-vehicle monitor support structure according to claim 3 of the present invention relates to the on-vehicle monitor support structure according to claim 1 or 2, wherein the monitor is a plate-shaped mounting base in the supporting portion (for example, the mounting base 38 in the embodiment). Supported by the monitor mounting portion (for example, the monitor mounting portion 41 in the embodiment), and a side portion of the monitor mounting portion of the mounting base is
A notch (for example, the notch 42 in the embodiment) is formed.

Since the notch is formed on the side of the monitor mounting portion of the mounting base, the monitor mounting portion can be easily deformed with respect to the mounting base in the event of a collision with the monitor or its support. As a result, the collision energy can be further absorbed.
