Description

BACKGROUND

The invention relates generally to motor vehicles, and more particularly, to a support device for a door assembly of a motor vehicle.

A door assembly of a motor vehicle generally includes various structures that are designed to promote structural integrity of the door assembly. In addition, safety features are integrated into the design of the door assembly. For example, portions of the door assembly may be designed to crush upon impact during a collision, yet maintain a desired shape during normal operation of the vehicle. Unfortunately, certain devices that provide structural integrity are too rigid and inflexible to provide the desired energy management during an impact.

DETAILED DESCRIPTION

FIG. 1 is a perspective view of an exemplary vehicle 10 that may include a support device in a door assembly of the vehicle. The vehicle 10, in this case a car, includes an interior 12 and an exterior 14. Furthermore, the vehicle 10 includes one or more door assemblies 16. As may be appreciated, a portion of each door assembly 16 is exposed to the interior 12 of the vehicle 10, and a portion of each door assembly 16 is exposed to the exterior 14 of the vehicle 10. Certain door assemblies 16 may include a support device that provides structural integrity during normal operation, and enables the door assembly 16 to crush during an impact. Such a support device may include a flexible support strap, such as a strap made from a webbed nylon material (e.g., seat belt material). The support device may extend between a first structure and a second structure, and may be configured to block movement of the first structure away from the second structure, and to enable movement of the first structure toward the second structure. As such, the support device may provide structural integrity to the door assembly 16, and enable the door assembly 16 to exceed applicable safety standards associated with impact energy management.

FIG. 2 is a cross-sectional side view of an embodiment of the vehicle door assembly 16, which includes a support device. The vehicle door assembly 16 includes a first structure 18 and a second structure 20. As illustrated, the first and second structures 18 and 20 may extend substantially parallel to one another. A support device 22 is coupled to the first structure 18, and to the second structure 20. The support device 22 may be any suitable flexible device, such as a flexible support strap manufactured from a webbed nylon material similar to the material used to manufacture seat belts, a molded strap, a die cut strap, a knit strap, and so forth. The support device 22 extends between the first structure 18 and the second structure 20, and limits the maximum distance between the first structure 18 and the second structure 20. Further, the support device 22 is configured to block movement of the second structure 20 away from the first structure 18, as illustrated by arrow 24. In addition, the support device 22 is configured to enable movement of the second structure 20 toward the first structure 18, as illustrated by arrow 26. As illustrated, the support device 22 is substantially flat (e.g., formed from a sheet of material), and is positioned horizontally. In other embodiments, the substantially flat support device 22 may be positioned vertically.

A first end 28 of the support device 22 is coupled to the first structure 18. The first end 28 of the support device 22 may be coupled to the first structure 18 in any suitable manner. For example, the first end 28 of the support device 22 may be coupled to the first structure 18 via one or more fasteners 30. In other embodiments, the first end 28 of the support device 22 may be coupled to the first structure 18 via heat staking. Likewise, a second end 32 of the support device 22 is coupled to the second structure 20. The second end 32 of the support device 22 may be coupled to the second structure 20 in any suitable manner. For example, the second end 32 of the support device 22 may be coupled to the second structure 20 via one or more fasteners 34. In other embodiments, the second end 32 of the support device 22 may be coupled to the second structure 20 via heat staking.

In the present embodiment, an armrest 36 may be mounted above the support device 22. For example, the armrest 36 may be positioned to cover the support device 22. In other embodiments, there may be a covering over the support device 22 in place of the armrest 36, or there may be no covering over the support device 22 such that the support device 22 is visibly exposed. By having the support device, the first structure 18 and the second structure 20 are supported against laterally outward movement without affecting the ability of the first and second structures 18 and 20 to crush during an impact.

FIG. 3 is a perspective view of an embodiment of an open storage compartment 38, which includes the support device 22. As may be appreciated, the open storage compartment 38 may be part of the vehicle door assembly 16. The open storage compartment 38 includes a first side wall 40, a second side wall 42, and a bottom portion 44 that form a cavity for storing items. As illustrated, the open storage compartment 38 includes the support device 22 extending between the first side wall 40 and the second side wall 42. The support device 22 is configured to provide structural support to the first side wall 40, and to the second side wall 42. The support device 22 may be configured to block movement of the first side wall 40 away from the second side wall 42, and to enable movement of the first side wall 40 toward the second side wall 42. Accordingly, the support device 22 may facilitate inward crushing of the first side wall 40 and/or the second side wall 42 during an impact.

In the illustrated embodiment, the support device 22 may be formed from a sheet of material, or any other suitable material, and is positioned vertically. In other embodiments, the support device 22 may be positioned horizontally or at any other suitable orientation. As may be appreciated, the support device 22 may be coupled to an inner surface of the open storage compartment 38 as illustrated, or the support device 22 may be coupled to an outer surface of the open storage compartment 38. Furthermore, the support device 22 may function as a divider within the open storage compartment 38. Thus, the support device 22 may not only structurally support the open storage compartment 38, but may provide additional functionality. The support device 22 may also include a decorative covering disposed around the support device 22 to enhance its visual appearance.

FIG. 4 is a perspective view of an embodiment of the support device 22. As illustrated, the support device 22 includes a flat side 46 having openings 48 for mounting the support device 22 to the first and second structures 18 and 20, or to the first and second walls 40 and 42. As may be appreciated, the support device 22 may include a grommet around each of the openings 48 to reinforce the support device 22. As discussed above, the support device 22 may extend between the first structure 18 and the second structure 20, and may be configured to block movement of the first structure 18 away from the second structure 20, and to enable movement of the first structure 18 toward the second structure 20. As such, the support device 22 may provide structural integrity to the vehicle door assembly 16, and may enable the vehicle door assembly 16 to exceed applicable safety standards associated with impact energy management.
