    Abstract: An emergency locking scat hinge device includes an inner and outer members defining a plurality of chambers therebetween, each having a relatively wide central part and end parts which get progressively narrower circumferentially away from the central part, a rolling member received in each of the chambers, a resiliently supported retaining member which retains each of the rolling members in the side central part of the corresponding chamber, and an acceleration sensitive locking device which actuates the retaining member so as to cause the rolling members to wedge between the inner and outer members. Because this seat hinge device permits free rotation under normal condition but prevents the relative rotation in a high acceleration situation, it can effectively increase the mechanical strength and rigidity of a seat back against tilting particularly when it is used on one side of a vehicle seat while a normal recliner hinge device is used on the other side of the vehicle seat.

    Abstract: In a vehicle occupant restraint system for restraining a lower part of a vehicle occupant, an arrangement for moving a restraining member (5) from a retracted position to a deployed position upon detection and/or prediction of a vehicle crash by a crash sensor (11,12) is adapted in such a manner that the restraining member cannot be made to move from the deployed position to the retracted position by an external force applied to the restraining member but can be made to move from the retracted position to the deployed position and from the deployed position back to the retracted position by a force transmitted from a power actuator (9, 15) to the restraining member via a power transmitting member (6, 7, 10). Thus, while the restraining member is capable of withstanding the load of restraining the vehicle occupant, even when the restraining member is deployed, it can be brought back to the retracted position so that the restraining system can be used repeatedly. This is particularly significant when the crash sensor includes a crash prediction sensor (12) because the prediction could be wrong and the restraining member may have to be deployed a number of times even when a vehicle crash has never occurred.
