Abstract

There is disclosed a vehicle door structure for an automotive vehicle comprising a door including an outer panel and an inner panel attached together to define a door cavity therebetween. An armrest secured to the door inner panel includes an inner cavity and is collapsible against the door inner panel upon the imposition of a predetermined level of force against the armrest. The armrest also includes an inflatable airpad in the inner cavity for receiving and venting a volume of air therein. The airpad includes an outlet aperture in fluid communication with the door cavity and an inlet aperture in fluid communication with a source of compressed air disposed remotely from the door. The armrest is collapsibly and retractably secured to the door such that the armrest projects into the vehicle when the door is closed and is retracted against the door when the door is open.

Claims

1. A vehicle door structure, comprising:

a door including an outer panel and an inner panel attached together and defining a door cavity therebetween;

an armrest secured to said door inner panel, said armrest defining an inner cavity and being collapsible against said door inner panel upon the imposition of a predetermined level of force against the armrest;

an inflatable airpad for receiving and venting a volume of air therein, said airpad being disposed in said inner cavity of said armrest and having an outlet aperture in fluid communication with said door cavity and an inlet aperture in fluid communication with a source of compressed air disposed remotely from said door; and

guide means for retractably extending the armrest such that said armrest projects into said vehicle when said door is in a first position and said armrest is retracted against said door when said door is in a second position.

2. A vehicle door structure according to claim 1, wherein said guide means for retractably extending comprises a slide mechanism having a fixed member secured to a backing plate in said inner cavity of said armrest and a movable member secured to said fixed member for reciprocating movement therealong.

3. A vehicle door structure according to claim 2, wherein said guide means further includes a spring member disposed between said movable member and an inner surface of said armrest, said spring member being operative to urge said moveable member toward said door inner panel upon deflation of said airpad.

4. A vehicle door structure according to claim 3, wherein said guide means is disposed in said inner cavity of said armrest.

5. A vehicle door structure according to claim 1, further including an outlet valve member disposed in said door inner panel in communication with said outlet aperture of said airpad, said outlet valve member being operative to open and deflate said airpad under the imposition of a predetermined level of lateral force against said armrest.

6. A vehicle door structure according to claim 5, wherein said outlet valve is further operative to open and deflate said airpad when said vehicle door is moved from a closed position to an open position.

7. A vehicle door structure according to claim 1, wherein said source of compressed air is an air compressor.

8. A vehicle door structure according to claim 7, wherein said inlet aperture of said airpad is fluidly connected to said compressor such that when said vehicle door is closed, said compressor is operative to inflate said airpad.

9. A vehicle door structure according to claim 1, wherein said armrest is manufactured from a flexible material.

10. A vehicle door structure according to claim 1, wherein said airpad is a bellows shaped member having a plurality of elongated chambers configured to fold upon one another in an accordion-like fashion upon deflation of said airpad.

11. A vehicle door structure, comprising:

a door including an outer panel and an inner panel attached together and defining a door cavity therebetween;

an armrest secured to said door inner panel, said armrest defining an inner cavity and being collapsible against said door inner panel upon the imposition of a predetermined level of force against the armrest;

an inflatable airpad for receiving and venting a volume of air therein, said airpad being disposed in said inner cavity of said armrest and having an outlet aperture in fluid communication with said door cavity and an inlet aperture in fluid communication with a source of compressed air disposed remotely from said door;

an outlet valve member disposed in said door inner panel in communication with said outlet aperture of said airpad, said outlet valve member being operative to open and deflate said airpad under the imposition of a predetermined level of force upon said armrest and deflate said airpad when said vehicle door is moved from a closed position to an open position; and

a pair of armrest guides operative to retractably extend the armrest into said vehicle when said door is in a first position and retract said armrest against said door when said door is in a second position, each one of said pair of armrest guides comprising a slide mechanism having a fixed member secured to said door inner panel, a movable member secured to said fixed member for reciprocating movement therealong, and a spring member disposed between said movable member and an inner surface of said armrest, said spring member being operative to urge said moveable member toward said door inner panel upon deflation of said airpad.

12. A vehicle door structure according to claim 11, wherein said source of compressed air is an air compressor.

13. A vehicle door structure according to claim 12, wherein said inlet aperture of said a airpad is fluidly connected to said compressor such that when said vehicle door is closed, said compressor is operative to inflate said airpad.

14. A vehicle door structure according to claim 11, wherein said armrest is manufactured from a flexible material.

15. A collapsible and retractable armrest for a door structure of an automotive vehicle, the vehicle having an air compressor disposed therein which supplies compressed air when said vehicle is running, the door structure having a door inner panel secured to a door outer panel and defining a door cavity therebetween, said armrest comprising:

an inflatable airpad for receiving and venting a volume of air therein, said airpad being disposed in an inner cavity of said armrest and having an outlet aperture in fluid communication with said door cavity and an inlet aperture in fluid communication with said air compressor disposed remotely from said door;

an outlet valve member disposed in said door inner panel in communication with said outlet aperture of said airpad, said outlet valve member being operative to open and deflate said airpad under the imposition of a predetermined level of force upon said armrest or when said vehicle door is moved from a closed position to an open position; and

a pair of guide members disposed in said armrest inner cavity for retractably extending the armrest into said vehicle when said door is in a closed position and retracting said armrest against said door when said door is in an open position, each one of said pair of armrest guides comprising a slide mechanism having a fixed member secured to said door inner panel, a movable member secured to said fixed member for reciprocating movement therealong, and a spring member disposed between said movable member and an inner surface of said armrest, said spring member being operative to urge said moveable member toward said door inner panel upon deflation of said airpad.
