Abstract

An integrated airbag and heating, ventilation, and air conditioning (HVAC) assembly includes an airbag module and an HVAC unit. The airbag module includes an airbag housing and an inflatable bladder at least partially disposed in the airbag housing. The inflatable bladder is movable relative to the airbag housing between a stowed position and a deployed position. The HVAC unit includes an HVAC housing. The HVAC housing supports the airbag housing.

First claim

The invention claimed is:

1. An integrated airbag and heating, ventilation, and air conditioning (HVAC) assembly, the assembly comprising:
a first airbag module including a first airbag housing and a first inflatable bladder at least partially disposed in the first airbag housing, the first inflatable bladder being movable relative to the first airbag housing between a stowed position and a deployed position;
a second airbag module including a second airbag housing and a second inflatable bladder at least partially disposed inside the second airbag housing, the second inflatable bladder being movable relative to the second airbag housing; and
a HVAC unit including an HVAC housing, wherein the HVAC housing directly interconnects the first airbag housing and the second airbag housing such that the first airbag housing and the second airbag housing are directly coupled to the HVAC housing.

2. The assembly of claim 1 , wherein the HVAC housing includes a first housing segment, a second housing segment and a third housing segment directly interconnecting the first and second housing segments, the air inlet valve is disposed closer to the the first housing segment is closer to the first airbag housing than to the second airbag housing, and the second airbag housing is closer to the second housing segment than to the first housing segment.

3. The assembly of claim 2 , further comprising at least one fastener directly coupling the first housing segment to the first airbag housing, wherein the at least one fastener extends only through the first housing segment and the first airbag housing.

4. The assembly of claim 3 , wherein the first housing segment is integrally coupled to the first airbag housing so as to form a first one-piece structure, and the second housing segment is integrally coupled to the second airbag housing to form a second one-piece structure.

5. The assembly of claim 4 , wherein the HVAC unit includes a blower motor assembly, wherein the blower motor assembly is disposed closer to the second housing segment than to the first housing segment.

6. The assembly of claim 5 , wherein the second housing segment is directly coupled to the blower motor assembly and the blower motor assembly is closer to the second airbag module than to the first airbag module.

7. The assembly of claim 6 , wherein the HVAC unit includes an air filter cover disposed between the first housing segment and the second housing segment.

8. The assembly of claim 7 , wherein the third housing segment is entirely disposed between the first housing segment and the second housing segment, and the third housing segment is directly coupled to the second housing segment.

9. A vehicle, comprising:
a vehicle body defining a passenger compartment;
an instrument panel disposed within the vehicle body;
a first airbag module at least partially covered by the instrument panel, the first airbag module including a first airbag housing and a first inflatable bladder at least partially disposed in the first airbag module, the first inflatable bladder being movable relative to the first airbag housing between a stowed position and a deployed position;
a second airbag module including a second airbag housing and a second inflatable bladder at least partially disposed in the second airbag module, the second inflatable bladder being movable relative to the second airbag housing; and
a heating, ventilation, and air conditioning (HVAC) unit at least partially covered by the instrument panel, the HVAC unit including an HVAC housing, wherein the HVAC housing supports the first and second airbag housings, and the HVAC housing directly interconnects the first airbag housing and the second airbag housing such that the first airbag housing and the second airbag housing are directly coupled to the HVAC housing.

10. The vehicle of claim 9 , wherein the HVAC housing includes a first housing segment, a second housing segment and a third housing segment directly interconnecting the first and second housing segments, the HVAC unit includes an air inlet valve disposed within the first housing segment, the first housing segment is closer to the first airbag housing than to the second airbag housing, and the second airbag housing is closer to the second housing segment than to the first housing segment.

11. The vehicle of claim 10 , further comprising at least one fastener directly coupling the first housing segment to the first airbag housing, wherein the at least one fastener extends only through the first housing segment and the first airbag housing.

12. The vehicle of claim 11 , the HVAC unit includes a blower motor assembly that is closer to the second airbag module than to the first airbag module.

13. The vehicle of claim 12 , wherein the HVAC unit includes an air filter cover disposed between the first housing segment and the second housing segment, the third housing segment is entirely disposed between the first housing segment and the second housing segment.

14. The vehicle of claim 10 , wherein the HVAC housing directly interconnects the first airbag housing and the second airbag housing.

15. The vehicle of claim 14 , wherein the HVAC unit includes a blower motor assembly, wherein the blower motor assembly is disposed closer to the second housing segment than to the first housing segment.
