Abstract

An inflatable interior panel for a passenger vehicle includes a non-inflatable section, and an inflatable section having a peripheral portion adjacent the non-inflatable section. The inflatable section is isolated from the non-inflatable section wherein the inflatable section is not in fluid communication with the non-inflatable section. The inflatable section includes a base wall including a slack material section enabling inflation of the inflatable section, and an inboard wall connected to the base wall to define an interior of the inflatable section. When the interior is pressurized the inboard wall is moved away from the base wall to an extended position with respect to the relatively stationary non-inflatable section.

Claims

1. An inflatable interior panel for a passenger vehicle, comprising:

a non-inflatable section; and

an inflatable section partially surrounding the non-inflatable section and fluidically isolated therefrom wherein the non-inflatable section and the inflatable section are part of a single blow-molded component including a shutoff section between the non-inflatable section and the inflatable section to prevent pressurization of the non-inflatable section, the inflatable section having a U-shaped central peripheral portion adjacent the non-Inflatable section, including;

a base wall including a slack material section enabling inflation of the inflatable section; and

an inboard wall connected to the base wall to define an Interior of the inflatable section, such that when the interior is pressurized the inboard wall is moved away from the base wall to an extended position with respect to the non-inflatable section, and the non-inflatable section is not significantly displaced into the passenger compartment of the vehicle so as to impact an occupant.

2. The inflatable interior panel of claim 1, wherein the shutoff section includes portions of the base wall and the inboard wall being pinched together substantially along the peripheral portion of the inflatable section.

3. The inflatable interior panel of claim 1, further comprising an inflator in fluid communication with the Interior of the inflatable section.

4. The Inflatable interior panel of claim 3, wherein the Inflatable section includes at least one of a shoulder portion, a hip portion, or a tunnel portion therebetween, and the inflator Is carried by one of the shoulder, hip, or tunnel portions.

5. The inflatable interior panel of claim 1, wherein the non-Inflatable section and the inflatable section are Individual components separate from one another.

6. The inflatable interior panel of claim 5, wherein the non-inflatable section is part of an injection molded body and the inflatable section includes a blow molded body.

7. The inflatable interior panel of claim 5, wherein the inflatable section is part of a blow molded panel.

8. The inflatable interior panel of claim 7, further comprising an inflator in fluid communication with the interior of the inflatable section and carried by the non-inflatable section.

9. An inflatable interior door panel of a passenger vehicle, comprising:

a non-inflatable armrest; and

an inflatable section partially surrounding the non-inflatable armrest and fluidically isolated therefrom wherein the non-inflatable and the inflatable section are Dart of a single blow-molded component including a shutoff section between the non-inflatable armrest and the inflatable section to prevent pressurization of the non-Inflatable armrest, the inflatable section being arranged for contact with an occupant of the vehicle and having a U-shaped central peripheral portion adjacent the non-inflatable armrest, including;

a base wall including a slack material section enabling inflation of the inflatable section; and

an inboard wall connected to the base wall to define an interior of the inflatable section, such that when the interior is pressurized the inboard wall is moved away from the base wall to an extended position with respect to the non-inflatable armrest, and the non-inflatable armrest is not significantly displaced Into the passenger compartment of the vehicle so as to impact an occupant.

10. The inflatable interior panel of claim 9, wherein the shutoff section Includes portions of the base wall and the inboard wall being pinched together substantially along the peripheral portion of the inflatable section.

11. The inflatable interior door panel of claim 9, wherein the non-inflatable armrest and the inflatable section are individual components separate from one another.

12. The inflatable interior door panel of claim 11, wherein the non-inflatable armrest is part of an injection molded body and the inflatable section includes a blow molded body.

13. The inflatable interior door panel of claim 11, wherein the inflatable section is part of a blow molded panel.

14. The inflatable interior door panel of claim 13, further comprising an inflator in fluid communication with the interior of the inflatable section and carried by the non-inflatable armrest.

15. A unitary, blow-molded, inflatable interior door panel for a passenger vehicle, comprising:

a non-Inflatable armrest;

an inflatable hip and shoulder section fluidically isolated from the non-inflatable armrest, the inflatable hip and shoulder section at least partially surrounding the non-inflatable armrest and having a U-shaped central peripheral portion adjacent at least a portion of the armrest, including;

a base wall including a slack material section enabling inflation of the inflatable section; and

an inboard wall connected to the base wall to define an interior of the inflatable section, such that when the interior is pressurized the inboard wall is moved away from the base wall to an extended position with respect to the non-inflatable armrest, and the non-inflatable armrest is not significantly displaced into the passenger compartment of the vehicle so as to impact an occupant;

a shutoff section between the non-inflatable armrest and the Inflatable section to prevent pressurization of the non-inflatable armrest wherein the shutoff section includes portions of the base wall and the inboard wall being pinched together substantially along the peripheral portion of the inflatable hip and shoulder section; and

an inflator in fluid communication with the interior of the inflatable hip and shoulder section to pressurize the interior and thereby inflate the inflatable hip and shoulder section.
