Abstract

A safety apparatus for a vehicle includes a coupling device to couple an airbag device with a cowl cross bar. The coupling device includes a plurality of mounting brackets coupled with the cowl cross bar while being spaced apart from each other by a predetermined distance, mounting b locks coupled with the mounting brackets, and fitting members protruding from an outer bottom surface of the housing and fitted on the mounting blocks.

First claim

The invention claimed is:

1. A safety apparatus for a vehicle comprising:
an airbag device including a housing having an open side to receive a folded airbag, an inflator provided in the housing to supply inflation gas to the airbag, and a cover to close the open side of the housing; and
a coupling device coupling the airbag device to a cowl cross bar installed in a width direction of a vehicle,
the coupling device including
a plurality of mounting brackets coupled with the cowl cross bar at predetermined distances, mounting blocks coupled with the mounting brackets, the coupling device further including support members provided on an upper outer surface of the housing and supported on the mounting blocks,
wherein the support members include fitting members fitted on the mounting blocks, at least one upper side of each mounting block inclined in a forward to rearward direction of the vehicle, and
wherein, an upper side of each fitted member corresponding to the at least one upper side of the mounting block is inclined in the forward to rearward direction of the vehicle.

2. The safety apparatus of claim 1 , wherein the mounting blocks are coupled with inner portions of the mounting brackets while facing each other, and
wherein each of the fitting members includes a front side protruding upward from an upper outer surface of the housing, the upper side of the fitting member extending from an upper end of the front side, and a lateral side connected to inner ends of the front and upper sides directed to an upper-lower central axis, and extending from the upper outer surface of the housing.

3. The safety apparatus of claim 2 , wherein the airbag device is provided in an opening of a low instrument panel positioned under a steering column provided at a side of a driver seat of the vehicle, and the cover is directed to a floor of the vehicle.

4. The safety apparatus of claim 2 , wherein each mounting block is provided on a mounting block surface with a protrusion, and each fitting member is provided in a front surface thereof with a through hole fitted around the protrusion.

5. The safety apparatus of claim 4 , wherein the protrusion of the mounting block includes a bolt, the through hole is fitted around the protrusion, and then a nut is coupled with the bolt.

6. The safety apparatus of claim 4 , wherein the airbag device is provided in an opening of a low instrument panel positioned under a steering column provided at a side of a driver seat of the vehicle, and the cover is directed to a floor of the vehicle.

7. The safety apparatus of claim 1 , wherein each fitting member and each mounting block are configured such that a predetermined interval is maintained between an inner surface of the fitting member and an outer surface of the mounting block.

8. The safety apparatus of claim 7 , wherein the airbag device is provided in an opening of a low instrument panel positioned under a steering column provided at a side of a driver seat of the vehicle, and the cover is directed to a floor of the vehicle.

9. The safety apparatus of claim 1 , wherein each fitting member is injection-molded such that the fitting member is integrally formed with the housing.

10. The safety apparatus of claim 9 , wherein the airbag device is provided in an opening of a low instrument panel positioned under a steering column provided at a side of a driver seat of the vehicle, and the cover is directed to a floor of the vehicle.

11. The safety apparatus of claim 1 , wherein the airbag device is provided in an opening of a low instrument panel positioned under a steering column provided at a side of a driver seat of the vehicle, and the cover is directed to a floor of the vehicle.

12. The safety apparatus of claim 1 , wherein the airbag device is provided in an opening of an upper instrument panel provided at a side of a passenger seat of the vehicle.

13. A safety apparatus for a vehicle comprising:
an airbag device including a housing having an open side to receive a folded airbag, an inflator provided in the housing to supply inflation gas to the airbag, and a cover to close the open side of the housing; and
a coupling device for coupling the airbag device to a cowl cross bar installed in a width direction of a vehicle, the coupling device including:
first and second mounting brackets for coupling with the cowl cross bar at spaced apart locations;
first and second mounting blocks coupled with the first and second mounting brackets, respectively, at least one upper side of each mounting block inclined in a forward to rearward direction of the vehicle; and
first and second support members provided on respective upper outer surfaces of the housing and supported on the first and second mounting blocks, respectively, the first and second support members each including fitting members fitted on a respective one of the first and second mounting blocks, an upper side of each fitting member corresponding to the at least one upper side of the respective one of the first and second mounting blocks and inclined I the forward to rearward direction of the vehicle.

14. The safety apparatus of claim 13 , wherein the first and second mounting blocks are coupled with distal ends of the first and second mounting brackets, respectively.

15. The safety apparatus of claim 13 , wherein the first and second fitting members are integrally formed with the housing.

16. The safety apparatus of claim 13 , wherein each mounting block is provided on a mounting block surface with a protrusion, and each fitting member is provided in a front surface thereof with a through hole fitted around the protrusion.

17. The safety apparatus of claim 16 , wherein the protrusion of the mounting block includes a bolt, the through hole is fitted around the protrusion, and then a nut is coupled with the bolt.

18. The safety apparatus of claim 13 , in combination with the vehicle.

19. The safety apparatus of claim 13 , wherein the first and second fitting members are formed with the housing and the first and second mounting blocks are independently formed from the housing and the first and second mounting brackets.

20. The safety apparatus of claim 13 , wherein the first and second mounting brackets are laterally outboard from the first and second fitting members of the housing and the first and second mounting blocks are laterally between the housing and the first and second mounting brackets, respectively.
