Abstract: [Problem] To provide a side airbag apparatus capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag, along with a passenger protection apparatus including this side airbag apparatus.
[Resolution means] A side airbag apparatus employed in a passenger protection apparatus according to the present invention includes: an airbag for restraining a passenger when expanded and deployed; and an inflator for supplying expansion gas to the airbag. The airbag includes: a first chamber which houses the inflator and is deployed outside in the vehicle width direction of the frame side wall part; a second chamber which is deployed inside in the vehicle width direction of the frame side wall part with respect to this first chamber; and an internal expanding part which is arranged in the second chamber and expands at least on the rear side of the vehicle in the second chamber via the gas flowing out from the first chamber. In addition, the first chamber is deployed such that at least a portion thereof, as seen from the vehicle side, overlaps the frame side wall part, while the second chamber is configured to be expandable via the gas flowing out from the internal expanding part.

Abstract: An airbag which is a constituent of a side airbag device installed in the vehicle seat according to the present invention is provided with a main chamber which deploys toward the front of a side support portion of the seat, and a sub-chamber which accommodates an inflator and which deploys at a position inward of the main chamber in the width direction of the vehicle. The main chamber is divided, by means of a baffle panel, into a main front chamber at the front, and a main rear chamber at the rear. The sub-chamber is linked to the main rear chamber at a side in the width direction of the vehicle. When the airbag is deployed, the baffle panel extends along a front edge of the sub-chamber, as viewed from the width direction of the vehicle.

Abstract: An inclination controlling mechanism of a seatbelt device is provided with: a pulley that converts an advancing/retracting movement of a cable of the cable advancing/retracting mechanism; a drive gear mounted around a pivot shaft of the pulley and synchronized with rotation of the pulley; and a driven gear mounted around a pivot shaft of a sensor housing so as to move in conjunction with a rotation of the sensor housing. The drive gear and driven gear engage with each other in a condition where a rotational track surface of the drive gear and rotational track surface of the driven gear intersect at a predetermined angle. As a result, an inertial body supporting surface serving as a sensor reference plane can be accurately maintained horizontally even at an arbitrary seatback recline angle, and thus the accuracy of the acceleration sensor can be improved.

Abstract: A belt tongue (1) having a tongue body (3) extending in an insertion direction (2), forming a belt slot (4) for guiding a belt crosswise to an insertion direction (2), and a blocking element (5), movably arranged in the tongue body (3) The belt is movable through the belt slot (4) in an unloaded pass-through position of the blocking element (5) and its mobility is at least inhibited by the blocking element (5) in a loaded position, created by a tensile force introduced into the belt. The belt is deflected by the belt tongue (1) in the fastened state in a loop shape. A cover (6) is provided at least on one side of the tongue body (2) and is arranged having at least one partial section (7) under the belt slot (4), and the partial section (7) directly adjoins the belt slot (4) and covers at least one part of the blocking element (5) in the pass-through position.
