Abstract
An inflatable restraint device for a vehicle is provided that includes an inflatable restraint cushion stored along a roof rail of a vehicle window in an undeployed state. A flexible loop is provided that is integral with the cushion, and an elongate cord member with a first end and a second end, the cord passing through the loop. The flexible loop slidably engages the cord during deployment of the inflatable restraint cushion, and supplies a tensioning force to the cushion.
Claims15
An inflatable restraint device for a vehicle having a side window, said restraint device stored in an undeployed state adjacent said window, comprising:
- an inflatable restraint cushion;
- a flexible loop integral with said cushion;
- an elongate cord member, said member having a first end attached to said vehicle proximate a first corner of said window, and a second end attached to said vehicle proximate a second corner of said window, said elongate cord member extending through said loop guide;
- said flexible loop slidably engages said elongate cord member during deployment of said cushion, an interface of said loop guide with said member providing a tensioning force to said cushion.
A restraint device deployable along a side window of a vehicle, said window having a first side and a second side, the restraint device comprising:
- an inflatable restraint cushion, said cushion stored at the roof of the vehicle in an undeployed state;
- a notched elongate cord member, said member having a first end and a second end, wherein said first end is attached to the vehicle proximate an upper corner of the second side of said window, and said second end is attached to the vehicle proximate a lower corner of the second side of said window;
- a loop integral with said cushion, said loop slidably engaging said elongate cord member upon cushion deployment, and said loop engaging a notch in said cord member to prevent travel of said loop along said cord member.
An inflatable restraint device comprising:
- a housing having an upper portion and a lower portion;
- an inflatable cushion stored in said housing in an undeployed state;
- a flexible loop integral with said cushion;
- an elongate member having a first end attached at said upper portion of said housing, and a second end attached at said lower portion of said housing, said elongate member extending through said loop;
- wherein
- upon deployment of said cushion, said loop slidably engages said elongate member, tensioning said cushion.
