1. Field of the Invention
The present invention relates to a vehicle interior assembly. More specifically, the present invention relates to a trim panel that attaches to two separate components of a vehicle interior assembly and includes an attachment section attached to one of the components that compensates for alignment variations between the two separate components.
2. Background Information
Conventional vehicle interior assemblies, such as dashboard assemblies, include many components that ideally attach to one another with specific positional orientations with respect to one another. For example, a conventional vehicle interior assembly is preferably mounted to a structural element within a vehicle passenger compartment. The structural element typically includes a support bracket that is rigidly fixed to the frame of the vehicle. An instrument panel assembly is installed to the support bracket. Typically, components such as an air conditioning evaporator housing, a heater core housing and/or ventilation ducts, are also fixed to the large bracket and/or to one another and are concealed by the instrument panel assembly. Such components are hereinafter referred to as concealed components.
A lower end portion of the vehicle interior assembly is at least partially covered with one or more trim panels to protect and further conceal the concealed components. In order to provide an attractive appearance, each of the trim panels is dimensioned to align and/or mate with various exposed portions of the vehicle interior assembly. In many designs, the trim panel typically must attach to the instrument panel assembly and/or a center console, and one of the concealed components.
In the manufacturing process of the concealed components and the exposed components of the instrument panel assembly, there are manufacturing tolerances and in the assembly process there are assembling tolerances. Specifically, during the manufacturing process, there are slight variations in the various components due to a number of factors, depending upon the manufacturing process. For example, components made of molded plastic, molded resin based materials or molded polymer based materials, factors such as the curing process, drying process, atmospheric conditions and condition of the molds used, all have an effect on the molded component. One such effect is that the overall dimensions of the component may differ slightly from component to component. This effect is usually referred to as a manufacturing tolerance. However, as long as the dimensions of the component are with a predetermined range of tolerances, the component can be used. When several components are assembled together, their respective tolerances are compounded.
During assembly of a plurality of components, further variations in the relative positioning of one component to another can also vary. For example, where a first component and a second components are fastened together, if the fastening apertures are larger that the fasteners, then the relative position and orientation of the second component relative to the first component can vary slightly yielding assembly tolerances.
The combination of manufacturing tolerances and assembly tolerances creates a problem when one attachment section of the trim panel is attached to a first component of a vehicle interior assembly and another attachment section of the trim panel is attached to a second component of the vehicle interior assembly. Specifically, if the first attachment section is rigidly fixed to the first component, the second attachment section might not align with the second component. In other words, the relative positions and orientations of the first and second components can vary from vehicle to vehicle. The trim panel may not fit properly in one vehicle, but may fit perfectly in another vehicle due to variations resulting from both manufacturing tolerances and assembly tolerances.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved trim panel attachment arrangement that takes both manufacturing tolerances and assembly tolerances into consideration. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
One object of the present invention is to provide a trim panel with positioning flexibility with respect to attachment to a fixed component.
Another object of the present invention is provide a trim panel with two separate attachment sections where a first attachment section attaches to a first component in a fixed positional orientation and a second attachment section that attaches to a second component but provides positional compensation that allows for manufacturing and assembly tolerances.
In accordance with one aspect of the present invention, a vehicle interior assembly includes a support member, a first component, a second component and a trim panel. The support member is located within a vehicle interior and has a first attachment section and a second attachment section spaced apart from the first attachment section. The first component is fixedly coupled to the first attachment section of the support member in a predetermined orientation relative to the support member within a first set of prescribed tolerances. The first component also has a third attachment section spaced apart from the first attachment section. The second component is fixedly coupled to the second attachment section of the support member in a predetermined orientation relative to the support member within a second set of prescribed tolerances. The second component also has a fourth attachment section spaced apart from the second attachment section and the third attachment section. The trim panel has a fifth attachment section and a sixth attachment section spaced apart from one another. The fifth attachment section is configured to fixedly attached to the third attachment section of the first component in a fixed positional orientation relative to the first component. The sixth attachment section is configured to attach to the fourth attachment part of the second component in a predetermined range of orientations in order to compensate for minor alignment variations resulting from the first and second set of tolerances.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment of the present invention.

The extension brackets 36 are separate bracket members that extend downward from a lower end of the main bracket 32 and are fixed by fasteners to a lower end of the main bracket 32. The extension brackets 36 are indicated in
The main bracket 32, the upper bracket 34 and the rear lower bracket 38 are all rigidly fixed to the steering member 30 and are also conventional vehicle elements. The main bracket 32, the upper bracket 34, the front lower bracket 36 and the rear lower bracket 38 are dimensioned to support the various components of the vehicle interior assembly 10, as described in greater detail below. It should be understood from the drawings and description herein that the steering member 30 includes a plurality of brackets, including two of the main brackets 32, several of the upper brackets 34, two of the extension brackets 36 and several of the rear lower brackets 38. However for the sake of brevity, only one of each of the brackets is depicted in
The rear lower bracket(s) 38 of the support assembly 20 basically define a first attachment section of the support assembly 20. The upper bracket(s) 34 of the support assembly 20 basically define a second attachment section of the support assembly 20.

The center console assembly 24 is a first component of the vehicle interior assembly 10 that fixedly coupled to the first attachment section of the support assembly 20 (a support member) in a predetermined orientation relative to the support assembly 20 within a first set of prescribed tolerances. The first set of prescribed tolerances includes manufacturing tolerances and assembly tolerances of the support assembly 20 and the center console assembly 24.
The heater core housing 26 (
As best shown in
Each of the L-shaped brackets 70 includes a downwardly extending section 70A. Each downwardly extending section 70A includes a pair of recesses 70B shown in
For the purposes of understanding the invention, the AC evaporator housing 28 and the heater core housing 26 can be considered as a single component of the vehicle interior assembly 10, as indicated in
Hence, one or both of the AC evaporator housing 28 and the heater core housing 26 can be considered as a second component that is fixedly coupled to the second attachment section of the support assembly 20 (a support member) in a predetermined orientation relative to the support assembly 20 within a second set of prescribed tolerances. The second set of prescribed tolerances includes manufacturing tolerances and assembly tolerances of the support assembly 20, the AC evaporator housing 28 and the heater core housing 26.
A description is now provided for the trim panels 12L and 12R is now provided with specific reference to
The trim panels 12R and 12L are preferably made of a molded polymer or plastic material, but can alternatively be made of an alternative backing material with a trim or facia material covering the backing material. The trim panels 12R and 12L are preferably made of a material that has some flexibility and resiliency.
Both of the panels 12L and 12R include a main body portion 72, hook members 74, snap-fit tabs 76, a mating edge 78 and a floor edge 80, whose features are described in detail below. Hence, description of the main body portion 72, the hook members 74, the snap-fit tabs 76, the mating edge 78 and the floor edge 80 applies equally to the panels 12L and 12R. However, the panel 12R includes a projecting panel portion 82, whereas, the panel 12L does not include a projecting panel portion. It should be appreciated from the drawings that the overall dimensions of the panel 12L differs from the overall dimensions of the panel 12R. However, it should be understood from the drawings and the description herein that basic purposes and functions of the main body portion 72, the hook members 74, the snap-fit tabs 76, the mating edge 78 and the floor edge 80 are not affected by dimensional variations.

Further, the hook members 74 of the trim panels 12L and 12R restrict the trim panels 12L and 12R against movement in directions perpendicular to the plane P.
A description of the snap-fit tabs 76 is now provided with specific reference to
The snap-fit tabs 76 basically define one attachment section on the trim panels 12L and 12R and the hook members 74 define another attachment section on the trim panels 12L and 12R. When the snap-fit tabs 76 are inserted into the apertures 62 of the center console 24, the trim panels 12L and 12R are in a fixed positional orientation relative to the center console 24 (a first component). However, the hook members 74 allow the trim panels 12L and 12R to attach to the L-shaped brackets 70, the AC evaporator housing 28 and the heater core housing 26 in a predetermined range of orientations in order to compensate for minor alignment variations resulting from the first and second set of tolerances.
The mating edges 78 of the trim panels 12L and 12R is shaped and dimensioned to align with the mating portions 58 of the center console 24. Further, the floor edge 80 is a lower edge of the trim panels 12L and 12R that are dimensioned to mate with an adjacent portion of the floor F.
A description of one method of assembling the vehicle interior assembly 10 is now provided with specific reference to
Next, the instrument panel assembly 52 is installed to the support assembly 20. The instrument panel assembly 52 can be installed as a single unit, or in separate sections thereafter, the center console 24 is installed to the support assembly 20. Finally, the trim panels 12L and 12R are installed to respective ones of the L-shaped brackets 70, and the snap-fit connections of the trim panels 12L and 12R are attached to the center console 24.
The snap-fit connection between the center console 24 and the trim panels 12L and 12R is a firm, not move-able connection in that once installed, the trim panels 12L and 12R retain their respective positional orientation with respect to the center console 24. However, the connection between the hook members 74 and the L-shaped brackets allows for positional adjustments. In particular, manufacturing tolerances and assembly tolerances cause the L-shaped brackets 70 to be located at slightly different positions and orientations relative to the center console 24 from vehicle to vehicle. The attachment sections defined by the L-shaped brackets 70 and the hook members 74 allow for position and orientation flexibility, and still maintain a reliable connection therebetween.
