DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail one embodiment of the invention. This discussion should not be construed, however, as limiting the invention to those particular embodiments since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention, the reader is directed to the appended claims.
Turning to FIG. 1, shown therein is an illustrative view of the present invention 10 in use. The present invention 10 is a vent addition for a vehicle 12 that is attached to the existing ventilation or air duct 14 located mid-way under the front seats 16 of some sports utility vehicles. The location of the existing ventilation duct 14 restricts air or heat from getting to the rear seat 18 occupant area. The present invention 10 discloses a vehicle air ventilation extension kit comprises an accordion-like hose 20 attached at one distal end to a provided adjustable vent 22 and at the other distal end, by means of a sleeve 24, to the existing vehicle air duct 14 located under the front seat 16. The air vent 22 of the present invention 10 is secured in place by means of hook and loop fasteners attached to the top portion of the provided vent 22 and its mating part attached to the bottom rear portion of the front seat 16. The flex hose 20 allows the front seat 16 to move backward and forward without the disconnection of attached parts.
Turning to FIG. 2, shown therein is a side view of the present invention 10 in use. The present invention 10 is a vehicle air vent extension kit comprising an accordion-like hose 20 and adjustable louvered vent 22. The accordion-like hose 20 is attached to the provided vent 22 at one distal end having a sleeve 24 that mates over the existing duct 14 located in the space between the floor board and the underside of the front seat 16 of a vehicle. The louvered vent 22 of the present invention 10 is secured by means of hook and loop material 26 attached to the top portion of the provided vent and to a mating piece of hook and loop material fastened to the bottom, rear portion of the vehicle front seat 16. The accordion-like hose 20 allows the seat 16 to move forward and back without disconnecting the vent extension. Air circulation arrows 28 are also shown.
Turning to FIG. 3, shown therein is a rear view of the present invention 10 in use. The present invention 10 discloses a vehicle air vent extension kit which comprises a flexible hose attached to the provided vent 22 and attached by its sleeve 24 to the existing duct 14 located under the front seat 16 of a vehicle. The air vent 22 of the present invention 10 is secured in place by means of hook and loop fasteners 26 attached to the top portion of the vent 22 and its mating counter part attached to the bottom rear portion of the seat 16. The flex hose allows the seat 16 to move back and forward without the disconnection of attached parts. The center console 30 of the vehicle is also shown.
Turning to FIG. 4, shown therein is an exploded view of the present invention 10. Shown is the present invention 10 comprising an extender for a vent 14. The extension has a shape conforming substantially to the existing vent 14 whereby one distal end of the vent extension has a low profile or low height sleeve 24 which is inserted over the vent and fictionally held thereto. The other distal end of the vent has a frame 22 with a flange 32 with hook and loop material 26 that is mated with hook and loop material selectively placed on the rear of the seat. The frame 22 houses a plurality of louvers 36 whereby the amount of air can be varied by adjusting at 34 the louvers. Positioned between the distal ends of the vent is an accordion-like conduit 20 whereby adjustment of the front seat is possible without affecting the vent extender.
Turning to FIG. 5, shown therein is a perspective view of the present invention 10. Shown is the vent of the present invention 10 mated to the existing motor vehicle vent 14 thereby extending the vent port to a position more ergonomically positioned to the rear seat passengers. The vent extension is comprised of an accordion-like 20 conduit having a fitting or sleeve 24 on one distal end for mating to the existing vent. The other end has a frame 22 that can be mounted to the rear of the front seat by means of hook and loop material 26. The frame houses a plurality of louvers 36 whereby the amount of air can be varied by adjusting the louvers. Adjustment at 34 of the front seat is possible without affecting the vent extension.
Turning to FIG. 6, shown therein is a cross sectional view of the mating vent apertures. Shown is a cross sectional view of the mating vent apertures, taken from FIG. 5 as indicated. The vent extension has a fitting or sleeve 24 that is attachable over the vent 14 aperture of the existing vehicle underseat vent 14. The fitting 24 is of substantially the same shape as the existing vent 14, so that once inserted it is frictionally held thereon. Turning to FIG. 7, shown therein is an enlarged view of the provided louvered vent 22. The present invention 10 is a vehicle air vent extension kit that is comprised of an accordion-like flexible hose having a sleeve on one distal end conforming substantially in shape to a vehicle's vent located underneath the front seat whereby the sleeve can be inserted over the existing vent and frictionally held thereto. The other end of the flexible hose is connected to a housing having a frame or vent 22 with a plurality of louvers 36 positioned therein. Located on the frame housing is a control mechanism at 34 for varying the inclination of the louvers 36 whereby they can be selectively positioned to direct the hot or cold airflow. The housing 22 has mating hook and loop material 26 fastened on the top that is mated to hook and loop material that is selectively fastened to the bottom backside of the front scat 16. The flexible hose provides for movement of the front seat 16 without dislocation of the provided vent 22 or sleeve attachment.
Turning to FIG. 8, shown therein is a flow chart of the present invention. Shown is the present invention which discloses a vehicle air vent extension kit comprising a flexible hose 20 attached to the provided vent 22 and attached by a sleeve to the existing duct 14 located under the front seat of a vehicle. The air vent 22 of the present invention is secured in place by means of hook and loop fasteners attached to the top portion of the vent and its counter part attached to the bottom, rear portion of the seat. The flex hose 20 allows the seat to move back and forward without disconnection of the attached parts. The present invention directs air circulation to the rear seat area of the vehicle. The existing air duct 14 is connected by a vent line 38 to the blower 40 of the vehicle.
