It is the same schematic longitudinal cross-sectional view. It is a cross-sectional view of a crime prevention device main body in the business vehicle of the present invention. It is a top view which shows the state which the airbag inflated in the crime prevention apparatus in this invention business vehicle. It is a schematic plan view which shows the state which attached the crime prevention apparatus in the business vehicle which concerns on Example 2 of this invention to the bus | bath.

The example which attached the crime prevention apparatus in the commercial vehicle of this invention to the taxi is demonstrated in detail as Example 1 based on drawing. The security device of the present invention includes a storage portion 2 having an openable / closable lid plate 1, a shielding airbag 3 that is folded inside the storage portion 2 and can be inflated and deployed, and a gas bag-like airbag 3. A security device main body 5 formed by an inflator 4 which is blown out into the airbag 3 and inflates the airbag 3 is used.

The main body 5 of the security device is located in the upper part of the column 9 constituting the security wall 6 on the side of the open space 8 on the passenger seat side, preferably in the inside of the taxi T in which the security wall 6 is installed on the back of the driver D, preferably driving. An activation switch 10 is installed at the height of the shoulder of the hand D with the cover plate 1 facing the open space 8 side, and activates the security device body 5 to inflate the airbag 3 by the inflator 4. However, it is installed in the vicinity of the driver's seat 7 that cannot be seen from the rear seat 11, and the activation switch 10 is connected to the security device body 5 through a lead wire (not shown).

The airbag 3 is made of “blade-resistant protective fabric” that is not easily cut even by a blade so that the airbag 3 is not cut by the blade of a burglar when it is inflated to reach the purpose of crime prevention. The “blade-resistant protective fabric” is not particularly limited, but preferably, for example, an ultra-high-strength polyethylene fiber having blade resistance and impact resistance is manufactured using the weaving technology of Nishijin Textile in Kyoto. It is recommended to use “Kyoto Nishijin yoroi”. Thereby, the airbag 3 can be prevented from being broken by a blade or other metal fittings.

In the security device for the commercial vehicle according to the first embodiment of the present invention, the driver D who feels the suspicious movement of the taxi passenger presses the start switch 10, the airbag 3 is inflated, and the driver seat 7 By eliminating the gap with the passenger seat, which is the open space 8, the driver D is blocked from the burglar in the rear seat 11 by the crime prevention wall 6 and the inflated airbag 3, and the violence from the burglar is prevented. It is configured to protect.

As shown in FIG. 3, the airbag 3 is normally folded and housed in the housing portion 2 so as to be inflatable by gas ejection, and the lid plate is turned on by the driver D being turned on. Simultaneously with the opening of the airbag 1, the airbag 3 instantly jumps out from the storage portion 2 to the passenger seat side, which is the open space 8, while expanding and expanding, and the driver is driven by the security wall 6 and the expanded airbag 3.
