Abstract

Apparatus for protecting vehicle occupants during side collision are disclosed, including at least one air bag mounted in a vehicle seat and a sensor for pyrotechnically initiating inflation of the air bag. The sensor is mounted on a frame connected to the vehicle body and on which the vehicle seat is mounted, and the vehicle body'"'"'s sides and/or doors include compression load transfer plates for the direct transmission of energy to the sensor for bag inflation upon deformation of the corresponding side and/or door of the vehicle body.

Claims

1. Apparatus for protecting occupants of a vehicle during side collisions, said vehicle having a vehicle body including sides and at least one adjustable vehicle seat including a frame mounted on said vehicle body, said apparatus comprising at least one air bag mounted in said vehicle seat, sensor means for initiating inflation of said at least one air bag, said sensor means mounted on said vehicle seat frame, and compression load transfer means mounted between at least one side of said vehicle body and said sensor means whereby deformation of said vehicle side causes activation of said sensor means by a direct transfer of energy through said compression load transfer means, said adjustable vehicle seat being adjustable within a predetermined range of adjustment, and said compression load transfer means having an extent of coverage corresponding at least to said predetermined range of adjustment of said adjustable vehicle seat.

2. The apparatus of claim 1 wherein said compression load transfer means includes a first compression load transfer member located in a door associated with said at least one side of said vehicle, and a second compression load transfer member comprising an actuator member for actuating said sensor means associated with said adjustable vehicle seat, said first and second compression load transfer members being closely juxtaposed with each other.

3. The apparatus of claim 1 including a gas generator connected to said at least one air bag, said sensor means comprising pyrotechnic sensor means, and including at least one pyrotechnic line connecting said sensor means to said gas generator.

4. The apparatus of claim 1 including actuator means for actuation of said sensor means, said actuator means including an actuator member extending substantially parallel to said sensor means, and a pivotable support plate supporting said actuator member, said pivotable support plate extending in a plane substantially perpendicular to said actuator member.

5. The apparatus of claim 1 wherein said vehicle body side includes a door having an outer surface, a reinforcing beam within said door and an inner side including a door panel spaced from said reinforcing beam, said compression load transfer means including plate means including longitudinal and lateral plate members in said door interior bridging said space between said reinforcing beam and said door panel.
