Padding and/or Expandable Armrest Integrated Into Upper Door of Vehicle

Abstract

A vehicle door padding feature and optional expansion feature that creates an armrest integrated as part of a vehicle door sill at the upper part of the door near the junction of the door covering and the window, and/or an expandable armrest in the door sill/upper door area via extension toward the inside of the vehicle.

Claims

1. A vehicle door sill (defined as the upper portion of a vehicle door where the vertical upholstery transitions to a partially or fully horizontal surface) that incorporates padding beyond that which is customarily found in the unpadded upholstered surfaces of the door, and sufficient to function as an armrest as defined by having some or all of the surface portion within 40 degrees of horizontal with at least the degree of padding found in other door or vehicle areas designated as having armrest functionality. Padding is defined as any material or substance which provides a cushioning affect beyond that which is found in the surface upholstery and underlying material customarily covering other portions of the vehicle door not intended as an armrest.

2. A vehicle door sill or portion of the upper door area (defined as the upper 30% of the door surface or any subset thereof) configured so that some or all of a padded feature extends inward on the side away from the window to form a larger and/or repositioned area to provide armrest functionality while in the expanded position, and optionally in the retracted position using some or all of the capability described in claim 1.

3. The invention described in claim 1 with two layers of padding so that the larger surface area created by the feature described in claim 2 is padded over some or all of its surface.

4. The invention as described in claims 1 and 2 with any form of embedded heat or variable padding (e.g. air chambers).

Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

[0014] FIG. 1 shows the invention configured as padding in the upward facing portion of the vehicle door sill to create a padded surface suitable as an arm and/or elbow rest.

[0015] FIG. 2 shows the invention configured as an extendable surface which can optionally be padded in both the stored (FIG. 1) or extended position to create a larger and/or inwardly positioned armrest feature.

DETAILED DESCRIPTION OF THE INVENTION

[0021] FIG. 1 shows an armrest integrated into the door as a layer of padding and with the optional extension feature shown in the extended position in FIG. 2 in the stored/retracted position in FIG. 1. The key feature of this embodiment of the invention is the layer of padding shown above the point marked as line number (1). The thickness of this layer need not be precise but must provide a degree of padding greater than that customarily found in other surfaces within the interior vehicle features where a simple layer of upholstery or plastic is found without meaningful padding or cushioning affect. The embodiment shown in FIGS. 1 and 2 extends the entire length of the door sill (2) however the invention could cover any subset of the door sill surface area. In this embodiment the invention is a padded layer along any subset of the door sill area indicated by number 2. This area is a typical and natural resting place for a passenger's arm and/or elbow or the driver's arm and/or elbow when in the driving position, however in the absence of the present invention it is found as an unpadded hard surface equivalent to other areas of the door surface, or a surface with no greater padding than that found on other door areas not intended as an armrest and is thus poorly suited for arm/elbow support. Prior art that provides armrest capability at or near the level of the door sill (2) are universally detachable, aftermarket additions and are not integrated with the construction of the door itself, either through original manufacture or permanent/semi-permanent add-on attachment as provided in the present invention.

[0022] The layer of padding shown in FIG. 1 may be integrated into the door at original manufacture, permanently affixed to the existing sill via adhesive, or semi-permanently attached via means such as loop and hook fasteners. It may exist in combination with the expandability feature shown in FIG. 2, however it is not required for the expandability feature (i.e. armrest capability may be provided only in the expanded position, only as a fixed, padded sill, or as both.)

[0023] The vertical area between lines 1 and 5 depicts a second optional layer of padding necessary to create a larger area of padded surface if the optional extension feature is implemented by hinging and rotating a portion of the padding inward toward the vehicle driver or passenger through an arc (3) around a hinge as further depicted in FIG. 2.

[0024] Note that the figures and this descriptive text could apply to either left or right-hand drive and could apply to either the driver or a passenger in part of the vehicle with a related window and sill structure.

[0025] The padded layers described above can be composed of any substance sufficient in function and depth to provide a degree of impact absorption and load distribution beyond that found on the minimally padded surfaces customarily found on vehicle interior coverings or other areas of the door in areas not suitable for supporting body parts (e.g. the dashboard surface or vertical door surfaces). Examples of substances that could provide this padding include but are not limited to various foam and gel materials, animal products such as down/feathers, and air capsules or chambers.

[0026] The current embodiment depicts a combination of a flat and horizontal surface with a sloping rounded feature, however various angles and shapes could be used provided that any portion of the surface provides arm and/or elbow support.

[0027] FIG. 2 shows the door sill surface extended to create a larger surface (4) for the armrest which can be expanded or retracted and, due to the nature of the padding, can (optionally) serve as an armrest in either the expanded position depicted in FIG. 2 (inwardly extended) or in the retracted position depicted in FIG. 1. The line in the center of the surface indicated by number 4 represents any form of hinge or pivot (e.g. rotation around fixed end points) or other apparatus (e.g. slide) which allows the armrest to shift between the stored/retracted position and the extended position. As in FIG. 1, while the current figures show the invention configured to create an armrest running the entire length of the door, the invention could be implemented as any subset of the length of the door. The extended portion of the armrest would be comprised of a firm but pliable padding such that it would not create a risk of injury in the event of a crash or other driving scenario.

[0028] The vertical area between lines 1 and 5 depicts an optional second layer of padding under the area covered in the retracted position such that a surface area greater than the extended portion can serve as a padded surface for arm and/or elbow support.

[0029] While the current embodiment shows the extensible, inward rotating surface as flush with the window in the stored (un-extended position), a flush fit to the window is not a mandatory feature of the invention and an extended surface could be created starting from an area in the door surface below the point of contact with the window.

[0030] Note that all of the features necessary to create the extended surface shown in FIG. 2, specifically the hinged/pivot surface (4), extension ability (3) and second layer of padding (5), are strictly optional and the invention can be implemented with the padded layer on a portion of the top of the door sill as the only feature. Alternately, the inwardly extending armrest can be implemented without the padded portion of the door sill in the retracted position shown in FIG. 1. This configuration would only create a padded feature in the extended position.

[0031] Either configuration shown in FIG. 1 or 2 could also optionally incorporate a form of embedded heat as an optional feature.

[0032] The invention does not preclude any other form of armrest on lower portions of the door such as those currently found below the upper third of the door where the present invention is focused.
