The presently disclosed embodiments are directed to the field of vehicle front end assemblies, and particularly to front bumper fascias and support members therefor.
Front vehicle assemblies are designed to meet a variety of requirements. The assemblies must absorb shocks and impacts from collisions. The assemblies must also have provisions for accommodating and supporting numerous components such as certain engine components, driving lights, vehicle accessory lights, hood engagement mechanisms, and depending upon the vehicle, may include various structures for improving vehicle aerodynamics. In addition, front vehicle assemblies are designed to exhibit favorable aerodynamic characteristics themselves, even if they are to receive additional aerodynamic components such as air dams or the like. Furthermore, vehicle front assemblies should be attractive and exhibit desirable aesthetic qualities.
Front bumper fascias are typically large panels that are designed to extend across the front of a vehicle, cover the shock absorbing components, improve vehicle aerodynamics, and provide an attractive appearance. Front bumper fascias are preferably one-piece, integrally formed components. A trend in the current vehicle market, is to use these large, one-piece front bumper fascias since they can be readily formed by injection molding techniques and designed to exhibit attractive styling and good aerodynamic properties.
One-piece bumper fascias are becoming increasingly complex. That is, many current vehicle fascias exhibit an array of compound curvatures and changing shapes at different regions of the fascia. This trend, coupled with such fascias being a single, integral piece, requires unique supporting structures for such fascias. Various designs have been proposed for supporting such fascias to a vehicle support frame or other member, such as described in U.S. Pat. Nos. 5,061,108; 5,580,109; 6,997,490; and 7,273,246. Although satisfactory, a need remains for yet further improvements in supporting a geometrically complex vehicle fascia.
More recently, increasing demands for lighter weight vehicles has prompted the use of fascias with thinner walls. It is typical for vehicle fascia walls to be less than 5 mm, less than 4 mm, and in certain applications, less than 3 mm. A consequence of using such relatively thin fascia walls, is that the resulting fascia is less rigid and thus prone to excessive deformation. Although a low rigidity and relatively flexible fascia can be made rigid by using an abundance of support members, the greater the number of support members used, the more complex is the resulting assembly. Such complex assemblies are time consuming and expensive to install.
Accordingly, a need exists for a single support member that can support a relatively large region of a front vehicle fascia, such as a front bumper fascia, to thereby eliminate the requirement for multiple support members and the attendant complexity, assembly time demands, and costs associated therewith.
A particular difficulty in supporting a geometrically complex fascia is the large number of peripheral regions resulting from an irregular fascia perimeter or outer edge. These peripheral regions typically extend within three dimensions. For example, a fascia having non-linear perimeter edges for accommodating an adjacent hood or light assembly presents regions of material in multiple dimensional planes that if not sufficiently supported, can fracture or deform if excessively loaded, can create unacceptable dimensional tolerances with respect to adjacent panels, excessively vibrate, and detract from the overall aesthetics of the vehicle.
Therefore, a need exists for a single support member that can support a peripheral region of a geometrically complex fascia, to thereby impart structural rigidity to that region and the rest of the fascia, maintain as-installed dimensional tolerances between the fascia and adjacent panels, and render that region relatively immune to excessive vibration.
The difficulties and drawbacks associated with previous-type systems are overcome in the present method and apparatus for a support member particularly adapted for supporting a vehicle panel.
In one aspect, the present invention provides a support member adapted for supporting a vehicle fascia. The support member comprises a longitudinal member having a first end, a second end opposite from the first end, and a body extending between the first and second ends. The body defines a front face, an oppositely directed rear face, and a top face extending between the front and rear faces. The support member also comprises a bracket projecting from the longitudinal member and disposed proximate the first end of the longitudinal member. The bracket is adapted for mounting to a vehicle structural component. The support member additionally comprises a first fastener affixed to the body of the longitudinal member. The first fastener is adapted to engage a vehicle fascia and provide support for the fascia against displacement out of a first plane. And, the member also comprises a second fastener affixed to the longitudinal member proximate the second end of the longitudinal member. The second fastener is adapted to engage the vehicle fascia and provide support for the fascia against displacement out of a second plane different than the first plane. The support member further comprises a third fastener affixed to the longitudinal member proximate the second end of the longitudinal member. The third fastener is adapted to engage the vehicle fascia and provide support for the fascia against displacement out of a third plane different than the first plane and the second plane.
In another aspect, the present invention provides a support member adapted to support a vehicle panel having a plurality of engagement members disposed along an inner face of the panel. The support member comprises a longitudinal member including (i) a first end for mounting to a vehicle support, (ii) a second end opposite the first end, and (iii) a body extending between the first end and the second end, in which the body defines a top face. The support member also comprises at least one fastener disposed on the top face of the body and adapted to engage an engagement member disposed on an inner face of the vehicle panel. The at least one fastener on the top face of the body provides support for the panel from being displaced out of a first plane generally parallel with a longitudinal axis of the body. And, the support member comprises at least one fastener disposed on the second end of the longitudinal member and adapted to engage an engagement member disposed on the inner face of the vehicle panel. The at least one fastener on the second end of the longitudinal member provides support for the panel from being displaced out of a second plane generally transverse to the longitudinal axis of the body. The support member further comprises at least one fastener disposed on the second end of the longitudinal member and adapted to engage an engagement member disposed on the inner face of the vehicle panel. The at least one fastener on the second end of the longitudinal member provides support for the panel from being displaced out of a third plane generally parallel with the longitudinal axis of the body.
As will be realized, the invention is capable of other and different embodiments and its several details are capable of modifications in various respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative and not restrictive.
The present invention provides a support member adapted for supporting a vehicle panel, and particularly a region of a geometrically complex vehicle fascia. The support member can be attached to a vehicle frame or other structure at only one end. The cantilevered mounting of the present invention member enables the member to provide support for a specific desired region or portion of a vehicle fascia. Moreover, the unique configuration of fasteners at a distal end of the member and/or along the length of the member provide a wide range of applications for the support members of the present invention.
Preferably, the present invention support member, such as support member 100, includes appropriately positioned and appropriately oriented fasteners so that when engaged to a fascia, the support member provides support to resist displacement out of at least one of planes X, Y, and Z; preferably to resist displacement out of at least two of planes X, Y, and Z; and most preferably to resist displacement out of all three planes X, Y, and Z.
The present invention support member can be used as a sole support member to stabilize, retain, and engage a relatively large region of a vehicle fascia, and particularly, an outwardly projecting peripheral region of a fascia.
Many other benefits will no doubt become apparent from future application and development of this technology.
The present invention support member can be formed from a wide range of materials, such as but not limited to metals, polymeric materials such as plastics, composite materials, or combinations thereof. Preferably the support members are formed from a plastic material having suitable physical characteristics. The present invention support member is preferably formed by one or more molding operations.
The fasteners used for fasteners 300, 400, and 500 can be nearly any type of fastener as typically used in the art. It is preferred that the fasteners be integrally formed with the support member. The fasteners can be resilient blind plastic clips with self-locking provisions as known in the art.
