Deflector for air bag deployment

Claim 2

In combination, a vehicle instrument panel having an opening therein, an air bag housing mounted on the vehicle and underlying the opening and having first and second walls spaced apart to define therebetween a storage cavity registering with the opening, a flange projecting from the walls outwardly away from the cavity and attached to the vehicle so that the housing is mounted with the storage cavity registering with the opening in the instrument panel, an air bag mounted on the housing and folded to store within the storage cavity between the first and second walls, a gas generator actuable to inflate the air bag and deploy the air bag through the opening, a door for closing the opening in the instrument panel to conceal the stored air bag and having a rigid substrate panel extending across the opening, said door having first and second ends respectively overlying the first and second walls of the housing, a hinge having one end attached to the first end of the door above the storage cavity and another end attached to the instrument panel so that the door is hingedly mounted for movement to an open position with respect to the opening when the actuation of the gas generator inflates the air bag, and a deflector plate having a flange portion attached to the housing flange along the first wall of the housing and a deflector portion raised above the flange portion by a step wall so that the deflector portion is parallel to the instrument panel and underlying the hinge and projecting toward the second wall to partially obstruct the deployment opening of the housing so that the path of the deploying air bag is deflected by the engagement of the air bag with the deflector plate to direct the air bag away from engagement with the hinge toward the second end of the door.

Claim 3

In combination, a vehicle instrument panel having an opening therein, an air bag housing having first and second walls spaced apart by end walls to defined therebetween a storage cavity registering with the opening, a flange projecting from the walls outwardly away from the cavity and attached to the vehicle so that the housing is mounted with the storage cavity registering with the opening in the instrument panel, an air bag mounted on the housing and folded to store within the storage cavity between the first and second walls, a gas generator actuable to inflate the air bag and deploy the air bag out of the storage cavity and through the opening, a door for closing the opening in the instrument panel to conceal the stored air bag and having a rigid substrate panel, said door having first and second ends respectively overlying the first and second walls of the housing, a hinge having one end attached to the first end of the door above the storage cavity and another end attached to the instrument panel so that the door is hingedly mounted for movement to an open position with respect to the opening when the actuation of the gas generator inflates the air bag, and a deflector plate fixedly attached to the flange of the housing at the first wall and extending uninterruptedly along the first wall and projecting inwardly from the first wall generally horizontally and in parallel spaced relation above the flange and below the hinge and sufficiently overtop the storage cavity and the folded air bag stored therein to partially obstruct the deployment opening of the housing so that the path of the deploying air bag is deflected by the engagement of the air bag with the deflector plate to direct the air bag away from engagement with the hinge mounting the first end of the door on the instrument panel.

Claim 4

In combination, a vehicle instrument panel having an opening therein, an air bag housing having first and second walls spaced apart by end walls to defined therebetween a storage cavity registering with the opening, a flange projecting from the walls outwardly away from the cavity and attached to the vehicle so that the housing is mounted with the storage cavity registering with the opening in the instrument panel, an air bag mounted on the housing and folded to store within the storage cavity between the first and second walls, a gas generator actuable to inflate the air bag and deploy the air bag out of the storage cavity and through the opening, a door for closing the opening in the instrument panel to conceal the stored air bag and having a rigid substrate panel, said door having first and second ends respectively overlying the first and second walls of the housing, a hinge having one end attached to the first end of the door above the storage cavity and another end attached to the instrument panel so that the door is hingedly mounted for movement to an open position with respect to the opening when the actuation of the gas generator inflates the air bag, and a deflector plate fixedly attached to the flange of the housing at the first wall and extending uninterruptedly along the first wall and projecting inwardly from the first wall generally horizontally and in parallel spaced relation above the flange and below the hinge and sufficiently overtop the storage cavity and the folded air bag stored therein to partially obstruct the deployment opening of the housing so that the path of the deploying air bag is deflected by the engagement of the air bag with the deflector plate to direct the air bag away from engagement with the hinge mounting the first end of the door on the instrument panel.
