Patent Images
1. A deployable member for covering an opening in a vehicle, comprising:
- an inflatable structure being stowed in an unexpanded and uninflated state adjacent to a first side of said opening;
a deployment mechanism being stowed adjacent to a second side of said opening;
a connector element disposed connectively between said inflatable structure and said deployment mechanism;
a plurality of guides for guiding said connector element between said deployment mechanism and said inflatable structure, said guides being disposed about said opening; and
a pulley assembly rotatably disposed at said second side of said opening, said first side and said second side being located opposite one another and. said connector element being configured to be wound from an undeployed state to a deployed state by said pulley assembly, said deployment mechanism rotates said pulley assembly causing said inflatable structure to be deployed across said opening from said first side to said second side, said inflatable structure being deployed by said pulley assembly prior to the inflation of said inflatable structure.

12. A deployable member for covering an opening in a vehicle comprising:
-
an inflatable structure being stowed in an unexpanded and uninflated state adjacent to a first side of said opening;
a deployment mechanism being stowed adjacent to a second side of said opening, said second side being in a facing spaced relationship with respect to said first side, said deployment mechanism includes an actuator, said actuator being connected to said inflatable structure by at least one connector element;
an inflator being in fluid communication with said inflatable structure;
a detecting means for detecting a predetermined condition, said detecting means causing said deployment mechanism to deploy said inflatable structure across said opening when said predetermined condition is detected, said detecting means causing said inflator to inflate said inflatable structure after said deployment mechanism has deployed said inflatable structure across said opening; and
a pulley system having a first pulley and a second pulley, wherein said connector element comprises a first portion and a second portion, said first portion connectively disposed between said inflatable structure and said first pulley, said second portion being connectively disposed between said second pulley and said actuator, wherein said first and second pulleys are disk shaped, said first and second pulleys being concentrically fixed to one another, and wherein said first pulley has a first diameter and said second pulley has a second diameter, said first diameter being larger than said second diameter.

14. A deployable member for covering an opening in a vehicle, comprising:
-
an inflatable structure being constructed out of a resilient material and being capable of being stored in a compacted condition at a housing, said housing being located at a first side of said opening;
an actuator being located at a second side of said opening, connector elements disposed connectively between said inflatable structure and said actuator;
a plurality of guides for guiding said connector elements between said actuator and said inflatable structure, said guides being disposed about said opening;
a pulley assembly rotatably disposed at said second side of said opening, said first side and said second side being located opposite one another and said connector elements being configured to be wound from an undeployed state to a deployed state by said pulley assembly, said actuator rotates said pulley assembly causing said inflatable structure to be deployed across said opening from said first side to said second side, said inflatable structure being deployed by said pulley assembly prior to the inflation of said inflatable structure. - View Dependent Claims (15, 16)
