There is. As an example, in Japanese Utility Model Laid-Open No. 4-49507, air outlets are opened in the center of the instrument panel near both ends, and an air conditioning duct extending in the vehicle width direction is provided in the instrument panel above the glove box. Are listed.

[0003]

[Problems to be solved by the device]

 However, recently, it is required to install an airbag device in order to improve the safety of passengers in the front seats, and in the above-mentioned conventional vehicle instrument panel structure, it is necessary to secure a space for installing the airbag device. It is difficult, and it is desirable to open the air conditioning air outlet as close to the occupant as possible, but it is difficult to secure the installation space for the air conditioning duct and the air outlet when an air bag device is installed. There was a problem. In addition, the airbag device is designed to secure the occupant by deploying the airbag due to the impact such as a collision, but in the event of an impact or sudden braking to the extent that the airbag does not deploy. In addition, when the occupant moves forward due to inertial force and presses the instrument panel, the airbag box of the airbag device is deformed to absorb the impact. However, since the air outlet is inserted into the outlet end of the duct and is supported by engagement with fixed claws, etc., when the impact is received, the air outlet is pushed into the duct by the impact force, and the impact absorption capacity There was a risk of running out.

An object of the present invention is to provide an instrument panel structure for a vehicle, which is provided with an air bag device and an outlet for conditioned air, and which can improve the impact absorbing ability.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the vehicle instrument panel structure of the present invention has a structure in which an air conditioning duct is arranged in the instrument panel and an air outlet is arranged at a position of the instrument panel facing the seat. A rib extending in the front-rear direction of the vehicle body is formed on the instrument panel portion of the. It is advisable to arrange the air outlet at the instrument panel position below the passenger side airbag device. Further, the instrument panel structure has an air conditioning duct inside the instrument panel, and an air outlet and an airbag device at the position of the instrument panel that opposes the passenger seat. The air outlet is formed in part.

[0006]

[Action]

 By forming ribs extending in the longitudinal direction of the vehicle body on the instrument panel portion around the air outlet, the support strength of the air outlet is increased and the impact absorbing effect is increased. Further, by forming an air outlet in a part of the airbag box of the airbag device, the impact absorbing effect can be further enhanced since the airbag box originally formed in the impact absorbing structure is used. it can.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The first embodiment will be described. In FIG. 1, the air bag device 4 is provided at a position corresponding to the passenger seat 3 of the instrument panel 2 of the vehicle 1, and the conditioned air is blown at a position below the air bag device 4. An exit 5 and a glove box 12 are provided.

2 and 3, the airbag device 4 includes an airbag module 6 including an inflator that generates gas when an impact of a predetermined value or more and an airbag that expands and deploys by the generated gas are built in. The instrument panel includes an air bag grid 61 that is pressed to open the inside of the vehicle when the airbag is deployed, and an air bag box 7 that accommodates the air bag module 6 with the air bag grid 61 attached to the opening inside the vehicle. It is buried inside the vehicle and only the air bag grid 61 is exposed inside the vehicle.

The air-conditioning air outlet 5, which is opened below the air bag grid 61, has a louver 51 that can freely swing inside, and its rear opening is connected to a heater duct 8 that extends laterally of the airbag box 7. It is provided with a fixing flange 52 at the periphery of the opening on the vehicle interior side and a fixing claw 53 protruding from the rear outer periphery of the fixing flange 52. Further, at the mounting position of the air outlet 5 of the instrument panel 2, a tubular projection 21 is formed on the instrument panel core 20 toward the vehicle interior side, and an inward flange 22 is formed in the vehicle interior opening of the projection 21. A plurality of ribs 9 extending in the vehicle front-rear direction are provided on the inner wall of the protruding portion on the rear side of the inward flange 22. Reference numeral 13 is a knee protector, 14 is an instrument panel support member, and 15 is an air conditioning duct communicating with an air outlet (not shown) provided at the center of the instrument panel 2.

A trim 10 is provided on the inner side surface of the inward flange 22 of the protruding portion 21 in the vehicle interior, a pad 11 is filled between the inward flange 22 and the trim 10, and the fixing flange 52 of the blow-out port 5 is a trim 10. The fixing claw 53 engages with the rear surface of the inward flange 22, and the rib 9 comes into contact with the outer surface of the air outlet 5 to sandwich it. With this configuration, the rib 9 can increase the support strength of the air outlet 5, and the impact absorption effect can be increased.

A second embodiment will be described with reference to FIGS. 4 and 5. A connecting duct 171 is integrally formed on a lower wall of the airbag box 17 in which the airbag module 6 having the airbag bag 16 is housed, and an opening end 172 of the connecting duct 171 on the vehicle interior side is connected to the instrument panel core 200. It is fitted and fixed in the receiving groove 201 formed on the rear surface of the instrument panel, and the opening end 202 of the instrument panel core 200 on the vehicle interior side is engaged and fixed by the outward flange 501 provided on the outer periphery of the air outlet 50 on the vehicle interior side end. Has been done. The rear end opening of the connection duct 171 is connected to the heater duct 8 which projects laterally and extends laterally of the airbag box 17.

According to this configuration, since the connection duct 171 is integrally formed with the airbag box 17 which is originally high in strength, the support strength of the air outlet 50 and the strength of the instrument panel 20 are increased, and the shock absorbing ability is improved. Can be improved.

[0013]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. By forming ribs extending in the longitudinal direction of the vehicle body on the instrument panel portion around the air outlet, the support strength of the air outlet is increased and the impact absorbing effect is increased. Further, by forming an air outlet in a part of the airbag box of the airbag device, the impact absorbing effect can be further enhanced since the airbag box originally formed in the impact absorbing structure is used. it can.
