Abstract
A vehicle air bag device can include an air bag retainer that has at least one clip located adjacent an opening at an outer periphery of the air bag retainer. An air bag chute can be located adjacent the air bag retainer and configured to guide the air bag along a deployment axis during deployment from the air bag retainer. The air bag chute can include a wall including a clip aperture opening located therein. The at least one clip can have an upper surface facing an upper surface of the clip aperture opening, and the upper surface of the at least one clip can be at an acute angle with respect to the deployment axis. The acute angle upper surface can extend from an interior of the air bag chute through the clip aperture and to an exterior of the air bag chute.

A vehicle air bag structural device, comprising:
- an air bag retainer configured to hold a vehicle air bag before deployment, the air bag retainer defining an opening through which the air bag passes during deployment, and at least one clip located adjacent the opening at an outer periphery of the air bag retainer;
- an air bag chute located adjacent the air bag retainer and configured to guide the air bag along a deployment axis and at least partially out of an upper opening in the air bag chute during deployment from the air bag retainer, the air bag chute having a wall including a clip aperture opening located therein, the clip aperture opening having an upper surface and a lower surface, the upper surface located closer to the upper opening in the air bag chute than the lower surface of the clip aperture opening, the air bag chute configured to move relative to the air bag retainer such that the upper surface of the clip aperture approaches the at least one clip during relative movement of the air bag chute towards the air bag retainer, the at least one clip having an upper surface facing the upper surface of the clip aperture opening, the upper surface of the at least one clip being at an acute angle with respect to the deployment axis and the acute angle upper surface extending from an interior of the air bag chute through the clip aperture and to an exterior of the air bag chute, such that if the air bag chute is moved downward towards the air bag retainer along the deployment axis a pre-set distance, the upper surface of the clip aperture contacts the upper surface of the at least one clip to cause the wall of the air bag chute to continue moving outward and downward along the acute angle upper surface of the at least one clip, the at least one clip having a lower surface opposed to the upper surface and configured such that during deployment of the air bag, the lower surface of the clip contacts the airbag chute to prevent the airbag chute from moving along the deployment axis, and the upper surface of the at least one clip extends away from the air bag chute and through the clip aperture at an angle different from an angle at which the lower surface of the at least one clip extends away from the air bag chute and through the clip aperture, wherein the wall of the air bag chute that is located immediately around the clip aperture opening defines a plane, and the plane intersects the acute angle upper surface of the at least one clip, and the lower surface of the at least one clip extends substantially perpendicular with respect to the plane such that the acute angle upper surface of the at least one clip promotes continued downward movement of the air bag chute with respect to the air bag retainer upon an object imparting force on an upper surface of the air bag chute while the substantially perpendicular lower surface of the at least one clip prevents upward movement of the air bag chute with respect to the air bag retainer during deployment of the air bag.
A structure for retaining and deploying a vehicle air bag, comprising:
- an air bag chute configured as a tubular structure having an upper exit aperture configured for the air bag to exit along a deployment axis during deployment, and a lower aperture, the chute including a side wall extending from the upper exit aperture to the lower aperture, the side wall of the chute including at least one opening extending therethrough with the side wall defining a peripheral surface of the opening;
- an air bag retainer located adjacent the lower aperture of the air bag chute and configured to store the air bag when in an undeployed state;
- a hook attached to the air bag retainer and including an upward extending portion, and an outward and downward sloped portion extending from an apex of the upward extending portion, wherein the apex of the upward extending portion is located within the air bag chute such that the outward and downward sloped portion extends from a location within the side wall of the air bag chute, through the opening in the side wall, and to a location outside the side wall of the air bag chute, wherein the outward and downward sloped portion of the hook forms an acute angle greater than zero with respect to a plane parallel with the side wall of the airbag chute and that contains the opening in the side wall, such that if the air bag chute moves towards the air bag retainer the peripheral surface of the opening contacts the downward sloped portion of the hook, and the hook including a lower surface opposite the downward sloped portion extending from a location within the side wall of the air bag chute, through the opening in the side wall, and to a location outside the side wall of the air bag chute, wherein the lower surface of the hook forms a substantially perpendicular angle with respect to the plane parallel with the side wall of the airbag chute such that the downward sloped portion of the hook promotes continued downward movement of the air bag chute with respect to the air bag retainer upon an object imparting force on an upper surface of the air bag chute while the substantially perpendicular lower surface of the hook prevents upward movement of the air bag chute with respect to the air bag retainer during deployment of the air bag.
A structure for retaining and deploying a vehicle air bag, comprising:
- an air bag retainer configured as a tubular structure with an upper opening at an upper portion of the tubular structure and a closed bottom at a lower portion of the tubular structure;
- an air bag chute configured as a tubular structure having an upper exit opening configured for the air bag to exit along a deployment axis during deployment, and a lower opening aligned with the upper opening of the air bag retainer tubular structure, the air bag chute including a side wall extending from the upper exit opening to the lower opening, the side wall of the air bag chute including at least one opening extending therethrough, the tubular structure of the air bag retainer being telescopically located within the tubular structure of the air bag chute such that the air bag chute is movable with respect to the air bag retainer along a telescoping axis direction if a predetermined force is applied to the air bag chute in the telescoping axis direction;
- and
- a hook extending from the tubular structure of the air bag retainer through the at least one opening in the side wall of the tubular structure of the air bag chute, the hook including an upper surface that is at an acute angle greater than zero with respect to the telescoping axis direction, and the upper surface of the hook faces upwards towards the upper exit opening of the air bag chute,
- the hook having a lower surface that extends one of:
- substantially perpendicular with respect to the telescoping axis direction, and
- at an acute angle with respect to the telescoping axis direction and downward away from the upper opening in the air bag chute, and
- the lower surface of the hook faces the at least one opening in the side wall of the air bag chute and is configured such that during inflation of the air bag the lower surface of the hook contacts the side wall of the air bag chute at the opening to prevent the air bag chute from displacement in the telescoping axis direction, the upper surface of the hook is made of a first material and the lower surface of the hook is made of a second material where the first material is different from the second material.
