Integral air vent and lamp assembly
View Patent ↗An integral air vent and lamp assembly for a vehicle passenger cabin includes a rotary vent housing and a hub defining an opening centered on a center axis of the vent housing having vent doors which open and close to admit or block airflow into the cabin. A lamp subassembly is disposed within the opening. The lamp subassembly may include a push-button micro-switch and light-emitting diodes (LEDs). A light diffusing lens and LED board may be positioned within a recess of an elongated T-shaped housing, which may include an axial member received by and rotating in conjunction with a gear element. The diffusing lens and LED board may be circumscribed by a bezel. A vehicle includes a power source, a body defining a passenger cabin, an air circulation device configured to move air to the passenger cabin, and the integral air vent and lamp assembly positioned in the passenger cabin.

6. The assembly of claim 1 , wherein the hub includes an annular wall and a plurality of air-diffusing blade members that extend radially outward from the hub toward the annular wall.
7. A vehicle comprising:
a body defining a passenger cabin;
a power source;
an air circulation device configured to move air to the passenger cabin; and
an integral air vent and lamp assembly having:
a rotary vent housing positioned in the passenger cabin in fluid communication with the air circulation device, and having a hub that defines an opening centered on a center axis of the rotary vent housing, wherein the rotary vent housing includes a pair of vent doors that open and close to respectively admit or block a flow of air from the air circulation device into the passenger cabin;
a gear set that is operatively connected to the pair of vent doors and that has a gear element; and
a lamp subassembly that is electrically connected to the power source, wherein the lamp subassembly is disposed within the opening of the hub, wherein the lamp subassembly includes an elongated axial member that is received by and rotates in conjunction with the gear element to open and close the pair of vent doors.
8. The vehicle of claim 7 , wherein the vehicle includes a headliner and a rear row of seats, and wherein the rotary vent housing is positioned with respect to the headliner.
9. The vehicle of claim 7 , wherein the lamp assembly includes a push-button micro-switch, wherein a depression of the push-button micro-switch changes an on/off state of the lamp assembly.
10. The vehicle of claim 7 , wherein the lamp subassembly includes a plurality of light-emitting diodes (LEDs).
11. The vehicle of claim 10 , wherein the lamp subassembly includes an elongated T-shaped housing having the axial member and defining a recess, a light diffusing lens, and an LED board on which is mounted the plurality of LEDs, and wherein the light diffusing lens and the LED board are positioned within the recess of the elongated T-shaped housing.
12. The vehicle of claim 7 , wherein the integral air vent and lamp assembly includes a bezel that is coaxially arranged with respect to the center axis, wherein the lamp assembly includes a light diffusing lens covering a light-emitting diode (LED) board, and wherein the light diffusing lens and the LED board are circumscribed by the bezel.
13. The vehicle of claim 7 , wherein the hub includes an annular wall and a plurality of air-diffusing blade members that extend radially outward from the hub toward the annular wall.
14. An integral air vent and lamp assembly for a vehicle having a body defining a passenger cabin, and also having an air circulation device and a power source, the assembly comprising:
a rotary vent housing in fluid communication with the air circulation device, and having a pair of vent doors and a hub, wherein the hub defines an opening centered on a center axis of the rotary vent housing and wherein the pair of vent doors are operable to open and close to respectively admit and block a flow of air from the air circulation device into the passenger cabin;
a lamp subassembly that is disposed within the opening of the hub, and that includes:
an elongated T-shaped member having an elongated axial member and defining a recess and an axial center channel within the elongated axial member;
a light-emitting diode (LED) board having a plurality of LEDs and a push-button micro-switch;
