Abstract

In one aspect of the present disclosure, a barrier is disclosed that is configured for connection to a vehicle dash assembly including an HVAC opening defined by a flange. The barrier includes a body that is configured to obstruct a flow of suds into the HVAC opening, and at least one clip that is supported on the body. The body includes open upper and rear portions to allow for continued airflow through the HVAC opening, and the at least one clip includes first and second clip members defining a receiving space therebetween that is configured to receive the flange such that the first and second clip members are positioned on opposite sides of the flange.

First claim

What is claimed is:

1. A barrier connectable to a vehicle dash assembly including an HVAC opening defined by a flange, the barrier comprising:
a body configured to obstruct a flow of suds into the HVAC opening, the body including open upper and rear portions to allow for continued airflow through the HVAC opening, wherein the body defines a horizontal length extending along a first axis generally parallel in relation to the vehicle dash assembly, a vertical height extending along a second axis generally orthogonal in relation to the first axis, and a lateral width extending along a third axis generally orthogonal in relation to the first and second axes, the body comprising:
a lower body portion including a lower end wall and a lower sidewall, the lower sidewall extending from the lower end wall along the third axis; and
an upper body portion including an upper end wall and an upper sidewall, the upper sidewall extending from the upper end wall towards the lower end wall along the third axis; and

at least one clip supported on the body configured for releasable connection to the flange, the at least one clip including first and second clip members defining a receiving space therebetween configured to receive the flange such that the first and second clip members are positioned on opposite sides of the flange, wherein the lower sidewall is discontinuous in configuration, the lower sidewall including first and second segments positioned on opposite sides of the at least one clip.

2. The barrier of claim 1 , wherein the upper end wall is spaced from the lower end wall along the third axis such that the upper end wall is positioned a first distance from the vehicle dash assembly and the lower end wall is positioned a second distance from the vehicle dash assembly, the second distance being less than the first distance.

3. The barrier of claim 1 , wherein the lower sidewall includes a variable thickness that tapers inwardly towards the vehicle dash assembly.

4. The barrier of claim 1 , wherein the first and second clip members are configured to engage the flange to restrict movement of the barrier along one or more of the first, second, and third axes.

5. The barrier of claim 4 , wherein the second clip member is configured for resilient deflection from an initial configuration to a subsequent configuration such that the at least one clip applies a force to the flange to secure the at least one clip to the flange.

6. The barrier of claim 5 , wherein the second clip member includes a first leg extending in a first direction and a second leg depending from the first leg, the second leg extending in a second direction transverse in relation to the first direction such that the second leg is deflectable in relation to the first leg.

7. The barrier of claim 6 , wherein the first clip member includes an upper engagement member and a lower engagement member, the upper and lower engagement members defining beveled surfaces.

8. The barrier of claim 7 , wherein the beveled surfaces extend along intersecting axes in correspondence with a contour defined by the flange to facilitate receipt of the flange within the receiving space.

9. A barrier connectable to a vehicle dash assembly including an HVAC opening defined by a flange, the barrier comprising:
a body configured to obstruct a flow of suds into the HVAC opening, the body including open upper and rear portions to allow for continued airflow through the HVAC opening, wherein the body defines a horizontal length extending along a first axis generally parallel in relation to the vehicle dash assembly, a vertical height extending along a second axis generally orthogonal in relation to the first axis, and a lateral width extending along a third axis generally orthogonal in relation to the first and second axes, the body comprising:
a lower body portion including a lower end wall and a lower sidewall, the lower sidewall extending from the lower end wall along the third axis;
an upper body portion including an upper end wall and an upper sidewall, the upper sidewall extending from the upper end wall towards the lower end wall along the third axis; and
an internal stiffener extending inwardly from the upper end wall towards the HVAC opening in the vehicle dash assembly, wherein the internal stiffener and the lower sidewall define a channel configured to receive the flange to restrict movement of the flange along one or more of the first, second, and third axes; and

at least one clip supported on the body configured for releasable connection to the flange, the at least one clip including first and second clip members defining a receiving space therebetween configured to receive the flange such that the first and second clip members are positioned on opposite sides of the flange.

10. The barrier of claim 9 , wherein the channel is generally U-shaped in configuration.

11. The barrier of claim 10 , wherein the channel defines opposite ends that taper outwardly towards the lower sidewall such that the ends of the channel receive the flange in an interference fit.

12. A method of inhibiting suds ingestion by a vehicle's HVAC system through an HVAC opening formed in a dash assembly of the vehicle, the method comprising:
releasably securing a barrier to a flange defining the HVAC opening to obstruct a flow of suds into the HVAC opening, the barrier including a body having an open upper portion and an open rear portion to maintain airflow through the HVAC opening, wherein securing the barrier to the flange includes connecting at least one clip to the flange, the at least one clip being supported on the body of the barrier, wherein connecting the at least one clip to the flange includes positioning first and second clip members on opposite sides of the flange such that the flange is positioned within a receiving space defined between the first and second clip members, wherein securing the barrier to the flange includes positioning the flange within an interior channel defined by the body, the channel extending along a perimeter of the barrier.

13. The method of claim 12 , wherein positioning the flange within the interior channel includes creating an interference fit between the flange and tapered end portions of the channel.
